Latency in GB version 10.0.2

All of a sudden, GB 10.0.2 is giving me latency on real instruments. It wasn't there from the begining.
I am running on a MBP core i7 with 16 GB ram, and nothing else running.
I have tried toggling inputs, rebooting my mac but nothing seems to help. The strange thing is, if I open MainStage 3, and have it running at the same time as GB, there is absolutely no latency on MainStage, but GB still has latency.
This must mean that my mac is running okay, the external equipment is okay. Not sure if GB and MainStage are using the same HW drivers though.
Does anyone have any ideas as to what could be wrong, or something I could try, please.
Thanks,
Mike

I'm sitting, here, and I have done since GB 10 was released, with the money in my bank to buy Logic X, but I'm simply refusing to do so, until I start to get more sense out of GB 10. You'd have thought Apple would sort these things out, because it must be costing them money. I would buy Log X, tomorrow, if I wasn't troubled that it might make my issues with my projects worse, and I'd be wasting my money. My iMac is not new, but it has a decent specification, all the Ram it can take, I run nothing but GB 10, when I'm trying to work, I have done my homework and I do all the things that should make GB run absolutely fine. I have a machine, in my iMac, with 16 times the Ram and a miles better/faster processor than my old Windows machine, but my old PC knocks spots off this thing. I'm keen to use GB 10 because I like very much what it should be able to do, with ease, and I'd love to use Logic, ultimately, but I'm bitterly disapointed with GB 10, because, although, once you finally finish a song, it sounds brilliant, it's a nightmare journey, just trying to get through it, using endless work arounds. GB 10 has cost me, literally months of wasted time.
Anyway, enough moaning, I suppose. Thanks for listening, good luck with your stuff guys..
Ontradio. :-)

Audigy 2 ZS crashing Sys

Hello!
I'm having massi've problems when using my Audigy 2 ZS (see below for my other hardware). What happens is, that my monitor is getting black for a second, picture comes back for a second, goes black again and so. Some seconds later the PC is no longer responding and I have to reset it. Mostly the operating system is damaged after this and my pc is not able to boot any more. Sometimes even other partitions on the dri've are damaged or gone. Before all this happens the system typically is running for hours or days without any problems. I can play games or listen to music or whatever. And suddenly it happens.
But now I found something that forces this behaviour. When i try to install FEAR (Sierra) the system is crashing for sure with the described symptoms.
When the audigy is not installed the system runs perfect for weeks without any crash. I've tried everything possible (changing PCI-slots, changing PCI-latency, different BIOS-versions, different (chipset-)drivers, RAM-Timings etc.) without any success.
Does anybody know what is going on and what to do? Is my audigy broken and should i send it in for warranty-replacement? What else can I do?
Thanks in advance,
Martin
Mainboard: Asus A8N-E

@John-CL:
I can do what I want, as long as the soundcard is installed the system crashes. Using the onboard audio instead of the audigy solves the problem. Don't see a problem with the memory sticks. Removed one (and then the other) and ran them slower than needed with no change.
As mentioned, the system runs fine without the card. It's also no problem if the card is only plugged in. But as soon as the drivers are installed it's just a matter of time.
There's only one more card installed (3Com NIC), but removed it also for testing reasons.
roblem with my hdd. Used another one for testing reasons with no difference. Even bought new ide-cable.
I know that many people are using this mainboard in combination with the audigy, so it can not be a common problem. The fact, that my system crashes reproducably when trying to install FEAR confuses me a little. Makes me think, it could be a software problem. But i have nothing special and no one else seems to have my problems. Maybe i simply send my card in for replacement and hope the best. Just don't know what else I could do...
Thanks for your answers so far

Audio MIDI latency problem (from iOS 7.0.6 till current version)

This problem started since i updated my iPhone 5 16GB and iPad Air 32GB Wi-Fi from iOS 7.0.4 to 7.0.6 (iOS 7.1 still have this problem):
i'm a DJ and using my iPhone and iPad as mobile but powerfull dj setup (with installed DJ Player ios app (http://djplayerapp.com)) and connected Vestax VCI-400 dj controller (with separate power adapter and powered hi-speed usb cable) via original Camera Connection Kit.
MIDI touch responce was perfect until upgrading to iOS 7.0.6. After that i got audio latency issues.
For example: i press to any button or moving crossfader and jog wheels for scratching on dj controller but sound starts just after a few seconds. DJ controller works fine (with usual aftertouch audio responce) with other music apps instead this one.
By the way: Connected AKAI MPK25 midi keyboard responce is OK in DJ Player and in other apps too (with separate power adapter and connected CCK via USB hub) without any problems after iOS updating on both Apple devices.
Main topic was started a month ago on the forum of DJ Player app developer: https://getsatisfaction.com/djplayer/topics/sound_delays_when_playing_from_vesta x_vci_400
Anyone have the same problems?

PROBLEM SOLVED!!! thanks for attention.

Windows Server 2012 Hyper-V network latencies

Hi All,
I have an issue with our Windows Server 2012 Hyper-V hosts that I can't seem to figure out. Situation:
2 x Dell PowerEdge R815 servers with AMD opteron 6376 16 core CPU's and 128 GB RAM running Windows Server 2012 with Hyper-V.
2 virtual machines running on the same physical host and connected to the same virtual switch show high TCP connection latencies. One virtual machines runs a SQL Server 2012 database instance and a Dynamics AX 2012 R2 instance. The other machine a
SharePoint 2013 instance and the AX client. We see latencies of 20ms and higher on most of the TCP connections that are made from the sharepoint machine to the sql server machine.
At first I thought it might have something to do with the physical NIC's. It turned out that VMQ wasn't correctly supported by the firmware of the Broadcom BCM5709c cards. By default this setting is enabled. Turning off the VMQ setting somewhat improved
the situation but the latencies are still at 8ms and higher.
What I don't understand is what influence enabling/disabling VMQ should have on network performance. As I understand it now virtual machines connected to the same virtual switch bypass the physical altogether. Another point is that VMQ should actually improve
performance, not decrease it.
Another question I have is about the various tcp offloading settings on the physical NIC's. After installing the new firmware and drivers from Dell most of these settings are set to disabled. The documents I have been able to find talk about Windows Server
2008, any thought how these settings relate to Windows Server 2012 and whether they should be enabled?
Thanks in advance for your time and thoughts
Kind regards,
Dennes Schuitema

Hi Denes,
Please try to update your BroadCom NIC driver version ,the newest version should be 7.8.51
For details please refer to following link :

I am getting messages that I can't download and read .pdf files since I have the wrong Adobe reader. I know about their security disasters of course, but I downloaded the latest version of Adobe Reader from the Adobe web site and I have other ,pdf file readers as well, and for some reason they won't work either. I have 5 computers running top end processors and RAM. By this I mean I have one, this one which I am using that has an AMD Phenom Black 3.2 Quad-core with 8 GBs of Corsair top DDR2 RAM, my other two AMD have either an Athlon II triple core with 4 GBs of DDR2 Corsair RAM, one with the Phenom X4 965 3.4 GHz Quad-core with 8 GBs of their best DDR2 RAM, and two Intels with the i7 920 Processors using the triple channel 1366 socket processors and one with 8 GBs of low latency DDR3 RAM and the other with 4 GBs of the same RAM. I am getting the message on this one, which has a fresh install of XP Pro X64 operating system, as do the other 4 as well. I have run Avast Business Pro Anti-virus on this one, which I am getting the message on with a single result which I deleted, and also both Spybot Search and Destroy, which came back clean as well as Malwarebytes Antimalware, which got a lot of tracing cookies now removed, and SuperAntiSpware which also found a few cookies also now deleted. Can you tell me what I need to do to get these files to show as .pdf files rather than as a clean blank page. One other issue is that I wish to know how to turn off my downloads so they are saved and Mozilla will give me the option of returning them instead of me losing them all together as it does now. Thanks for your assistance. If there is another Adobe reader I should download and install, could you provide me with the link to it? I appreciate your assistance here
== When I download and try to read a .pdf file and when I am asked to turn off all Firefox files and if I do, I lose them since I need to know how to save them without rebooting my computer.

Brilliant! Problem solved! Thanks so much.

I am having much trouble with the new reminders in IOS7 and how it interacts with Outlook Exchange. Many features lost in the new version.

When I downloaded IOS7, I found that the reminders/task app and how it interacts with Outlook Exchange is much more difficult to use. Some of the issues that I am having are...
1. Trying to edit my task on my phone is not possible, if the notes are lengthy. When you click on the text to edit data near the top, it will scroll to the bottom and not allow you to edit the text because you cant see it.
2. Now all of my task are in one long list. I can not move from day to day like we could in previous version IOS6
3. When I do edit a short task reminder and click done, it crashes and completly goes away. It does save the edit though
4. You can only add task at the bottom of each days reminders. This is very inconvient and much more difficult than IOS6
5. There is a major delay or latency when interacting inside of reminders in this version. Much more than IOS6. It is very unstable and quirky.
I have never seen Apple take a step back with a product until now. I am a huge Apple fan and always will be, so I am hoping they make enhancements to fix these issue. It is a big time prodcutivity killer.
Thanks for any and all help you can give.

Some power supplies or designed so that if there is a short or overload they shut them selfs off and some will not turn back on. Some have a relay that will click back on and work, some you have to cycle the power switch. Those that won't come back on will have to be replaced. I'm not saying that yours is that type as I have no way of telling. But if you have a friend who will loan you a good power supply you might try it. As someone else said just turning off the power will not darn all the power from some motherboards. To test this turn off your power supply than turn on the computer with the start botton. Mine will flash the lights and fans will start to spin than die. So every time you turn off computer to work on it. After turning off PSU hit the start botton to drian any power left in it before working on it. Also do this after unplugging it just to make sure.

My wireless router is that TP-LINK and it`s firmware is updated to the latest version. (I using the stock firmware). There are no wireless network in range, that are using the same channel as mine is. The latency is happening to my friends connected to my router too. I am using wicd for network manager, and wicd-curses for network manager front-end.
I will post more info if needed.
Please advise me what can I do.
Regards

Okay well I can see nothing that would cause this in anything you've posted. Especially if your friends are experiencing this too.
I would either try downgrading the firmware (If after upgrading this happened). However, I see that your TL-WR1043ND is VERY well supported by Open-WRT. You may want to give it a look.
Remember that the WiFi channels are overlapped. Try getting as far away as possible from other networks.
Ensure you are running WPA-PSK with the AES cipher and a key of 63 pseudorandom characters. This way others are not using your WiFi to torrent and suck bandwidth.
Try to stick to 802.11g but if at all possible go with 802.11n. Also if possible move up to the 5Ghz band to get out of the way of other things using the 2.4Ghz uncontrolled spectrum block.
If your router is running things like DHCP, DNS, FTP, SMB, SSH, NTP, VPN, Etc... Quit it. Your TL-WR1043ND is running a 400Mhz processor with 32Mb of memory.
That's basically all the advice I've got. Hope that get's the ball rolling on fixing this for you.

My Latency is at 1900-2600ms, and, I would like to know if there is any way to fix it or lower it

I have not found any solutions to this, sometimes my Latency can be at 50-80ms, and i don't know why now it is constantly at 2000 ish. It annoys the crap out of me because a simple page on google takes FOREVER to load.
This is the System Info.

Ive gotten a new router in the past, that did nothing, and i am confused because on my tablet, the ping is a normal 70ms, this is why i need help with lowering it on the computer, as you know of you've had similar problems, they are very annoying to deal with. I have no idea what seems to cause this, but something i find interesting, is that when i restart the computer, for about 15 mins after it was restarted, the ping is normal, then it just jumps back up to the 2000's.
I have the latest software OS X Maveriks 10.9.5.
Please help i have been having this problem for a very long time and have never been able to fix it

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does my 10GB iSCSI setup seem see such high latency and how can I fix it?

I have a iscsi server setup with the following configuration
Dell R510
Perc H700 Raid controller
Windows Server 2012 R2
Intel Ethernet X520 10Gb
12 near line SAS drives
I have tried both Starwind and the built in Server 2012 iscsi software but see similar results. I am currently running the latest version of starwinds free
iscsi server.
I have connected it to a HP 8212 10Gb port which is also connected via 10Gb to our vmware servers. I have a dedicated vlan just for iscsi and have enabled
jumbo frames on the vlan.
I frequently see very high latency on my iscsi storage. So much so that it can timeout or hang vmware. I am not sure why. I can run IOmeter and
get some pretty decent results.
I am trying to determine why I see such high latency 100'ms. It doesn't seem to always happen, but several times throughout the day, vmware is complaining
about the latency of the datastore. I have a 10Gb iscsi connection between the servers. I wouldn't expect the disks to be able to max that out. The highest I could see when running IO meter was around 5Gb. I also don't see much load
at all on the iscsi server when I see the high latency. It seems network related, but I am not sure what settings I could check. The 10Gb connect should be plenty as I said and it is no where near maxing that out.
Any thoughts about any configuration changes I could make to my vmware enviroment, network card settings or any ideas on where I can troubleshoot this. I
am not able to find what is causing it. I reference this document and for changes to my iscsi settings
http://en.community.dell.com/techcenter/extras/m/white_papers/20403565.aspx

I frequently see very high latency on my iscsi storage. So much so that it can timeout or hang vmware. I am not sure why. I can run IOmeter and
get some pretty decent results.
I am trying to determine why I see such high latency 100'ms. It doesn't seem to always happen, but several times throughout the day, vmware is complaining
about the latency of the datastore. I have a 10Gb iscsi connection between the servers. I wouldn't expect the disks to be able to max that out. The highest I could see when running IO meter was around 5Gb. I also don't see much load
at all on the iscsi server when I see the high latency. It seems network related, but I am not sure what settings I could check. The 10Gb connect should be plenty as I said and it is no where near maxing that out.
Any thoughts about any configuration changes I could make to my vmware enviroment, network card settings or any ideas on where I can troubleshoot this. I
am not able to find what is causing it. I reference this document and for changes to my iscsi settings

Thank you for your time.
If both StarWind and MSFT target show the same numbers I can guess it's network configuration issue. Anything higher then 30 ms is a nightmare :( Did you properly tune your network stacks? What numbers (x-put and latency) you get for raw TCP numbers (NTtcp
and Iperf are handy to show)?

T520 Sound Issues...Latency Spikes...SIMPLE SOLUTION !!

Hello All,
Many of us T520 owners have had problems with skipping/cracking/distorted audio as a result of DPC Latency Spikes. I have been reading every available thread on the topic and I found a simple solution in a T420 thread that I wanted to share with any T520 users that may have overlooked it.
The Latency Spikes experienced by many users (including myself) were caused by the Ethernet Driver (Intel 82579LM Gigabit Adapter). The current T520 is loaded with Intel driver version 11.12.38.2001. However, if you revert to version 11.12.36.0 the issue disappears. You can download the driver directly from the HP website. (It is no longer available on the Lenovo Support Page)
Thanks again to the original T420 poster and GOOD LUCK!
Moderator Note: Links fixed.

Just bought a NEW T520 with nVidia 4200 , i5 , 4GB, 500GB (7K2 rpm)....
Had before Y560p, & resplved problems with that by reversing the bios to an older one, I didn't found it on Lenovo web, but hte guy from Thailand sended it to me on e-mail (he had problems too).
So it was OK but I wanted the best U can buy... & bought T520.... Had a BIG problem on a gig 1st time a used it ...
Music just stopped for a second or two.... big spike in latency monitor (I started it before work)... then I put to OFF WiFi (on the switch - left side). OK for about 45 min, then AGAIN.... I have gone crazy .... bought a double priced laptop & have problems again ??!?! Is that possible ?!?!?
BTW the drivers on my LAN card are : 11.15.16.0
Anyone know the answer for this ? Thanks in advance, while I'm reconsidering (not glad about that cose I love the Lenovo brand) buying the Apple Mac Book Pro...

DPC latency + audio/mouse skip and stutter on t420s

Hello fellow thinkpad owners,
I have a new t420s (41717FU) core i7, 8GB RAM, and NVS 4200M discrete, win 7 64-bit pro. I use the minidock with 2 external 28" displays on DVI out.
I discovered major issues with latency with this machine; very noticeable loss of control for about half a second, plus annoying audio stutter, especially concurrent with network activity. This is quite frustrating, especially for a machine that is supposed to be high end core i7 with discrete graphics. I had a t410s previously and also had latency problems, and I know this is a real problem with several different models (just search 'annoying audio') on the forums.
I have used dpc latency checker as well as latency mon and narrowed the probable culprit to the network drivers associated with the gigabit ethernet. It took me a while to discover the relationship to the Intel 82579LM, since LatencyMon will identify the problem with NDIS.sys or NETIO.sys, giving sporadic latencies over 20000 microsecs, which made me think it was a Win 7 tcp stack issue or maybe some internal windows firewall blocking. During these spikes, the audio stutters, the mouse won't move, everything on the system just stalls for a split second. Temps on CPU seem within normal limits at about 70-80C. I've read everything I could find about this issue, including problems with NVIDIA drivers, ACPI, firewall/antivirus, etc etc, and tried most of those suggestions.
I spent a long time doing all kinds of testing, putting the machine on AC power and max performance, shut down various devices, disabled any component power-off states, disabled NVIDIA and displays, changed bios settings etc.
After all of this, I *know* my issue is related to the Intel Ethernet component, because if I disable it and use wireless connectivity (or no network at all) the problem simply goes away. Surprisingly, the wireless Centrino adapter, though slower, functions without any problem affecting DPC latency and I have no stutter with that (many have previously identified the wireless adapter being a problem especially related to power mgt).
Unfortunately, I require an ethernet connection. So just disabling that adapter is not an option. Here is what I've done to workaround the issue, though I wish it would be fixed for good with some kind of update from Lenovo, though I've called and emailed them and they seem to be ignoring this issue.
**** UPDATE 3/1/2012 ****
SOLUTION RIGHT HERE: INSTALL AN OLDER NETWORK DRIVER FROM HP (sounds crazy, but it works). See below link to driver download.
I (and many other owners of T420, 520, etc - see other posts if you doubt it) have *no* latency after installing this older driver from HP. But as soon as I install the Lenovo-provided driver 11.12.38.* or any later one from Microsoft or the Intel generic driver (intel no longer publishes the old driver), I see *immediate* problems with latency, mouse and audio stutter. But use the driver published by HP (specifically version 11.12.36.0, published 5/4/2011) -- Problem solved! I tested with streaming and browsing for several hours and no spiking or stutter.
Here's where to get the english language download from HP: >> DRIVER DOWNLOAD PAGE HERE <<
Lenovo, PLEASE: this is strong evidence of a faulty driver for those of us with a t420s (and other thinkpad users out there using the intel 82579LM chip under x64). I encourage you to review this solution and engineer an update for the Intel gigabit adapter, or at minimum, roll back to the older driver or some Lenovo approved derivative so it doesn't cause all of us notebook users such a major headache. It's very bizarre that we would need to go to another manufacturer to get a working driver...I was ready to return the machine over this issue!
Aside from that adapter problem, I've been pleased with the t420s performance and features. Thanks again lopiuh for this workaround.

***** END UPDATE *****
**** OLDER STUFF I TRIED, which somewhat helped, but the real solution is to use the old HP DRIVER above. ******
Basically, my approach was to reduce the 'auto' parameters for the adapter, to reduce the amount of logic running on the adapter itself.
1. Install the PRO set extension tools on this adapter, so you can more easily manage advanced settings. I think Lenovo offers a version in the driver downloads area which adds this management extension, but it is not the standard one offered by the system update utility, and the intel site has a later driver, so I gambled and downloaded the latest version from Intel for this adapter. It installed without issue, but I'm sure Lenovo would prefer you stick with their OEM packages. Anyway, here's the one I used: http://www.intel.com/support/ethernetcomponents/controllers/82579/sb/CS-032239.htm (link near the top for the download). You may want to make a system restore point before you install any drivers outside of OEM approved.
2. Change the default settings for the adapter in Device Manager. Right click properties for the Intel 82579LM in Network Adapters. Change the link speed (if the extension was installed properly, you'll see the intel logo on the tab for Link Speed, and a choice for Speed and Duplex. Change this from 'Auto Negotiate' to whatever speed your network is. I have gigabit full duplex, and that worked for me. This by itself was the biggest improvement with DPC latency.
3. Go to the Advanced tab. I took the approach that I wanted to disable as much 'auto' stuff as possible, and force the adapter to use a particular setting. Thus:
Interrupt Moderation: Disabled
Jumbo Packet: 9014 bytes (I have several devices that can use bigger packets on network, such as readynas)
Performance Options: click properties: Flow control - Disabled; Interrupt Moderation Rate - Off; and then double the receive and transmit buffer sizes (for me this was 512 and 1024 respectively).
I hope this may be helpful to some other owners, but I don't work for Lenovo or Intel so please don't blame me if something goes wrong during your tweaking. This worked (for me) to significantly reduce stuttering problems, though they are not completely gone; your mileage may vary. If you have this same problem, I'd appreciate if you would post about it so I can understand if it is a more widespread problem.
Good luck, mojojojo

Solved!

Hi mojojoj0
For my W520, up till now I do not have latency issues. My set of configuration for Intel NIC is slight different.
2. This may cause connection problems when you are connecting to different network. Different network (switches, routers) have different configuration. Previously I set it to Gigabit Full Duplex, I can't connect to any 10/100 network until I change it back to Auto negotiation.
I would suggest changing back to auto negotiation when you are connecting to outside network, not all places are using gigabit switches.
3. Interesting, I guess I would try it and feedback and see how much improvement for network performance.
From what I know, increasing receive and transmit buffer improve NIC and network card performance, but computer may slightly more memory.
Maybe you can try this, part of my settings:
Large Send Offload (IPv4) & (IPv6) Enabled
TCP & UDP Checksum Offload (IPv4) & (IPv6) Tx & Rx Enabled
IPv4 Checksum Offload Tx & Rx Enabled
Hope this helps!
Cheers

Version 10.1.8 SLOW and locks up Windows Explorer when attempting to select multiple files to open.

User contacted L1 Tech Support when browsing server & attempting to simply select multiple adobe pdf's. Passed to Support level 2. Level 2 deemed was not server as they could recreate the issue on any machine running 10.1.8 by copying in question pdf's or a group of random others to a local machine & get the same result.
Other common observations, have latency when opening up pdf files via IE in ERP application. Seems to be an issue with Adobe either versioning or inherent problems. ( have read through many "setting mod's & have verified "Starting in protected mode" is off ) any help or direction is much appreciated. Next steps will be to open PDF's with another product.
Consistent results on 300+ machines some XP some W764bit.
Thanks!

Hi ChesterCopperpot,
Could you please elaborate your issue and provide more information like the exact version of internet explorer and how do you try to open multiple Pdf document using internet explorer at a time.
Also tell me if you have attempted to disable some third party brower extention and plug-ins.

Windows latency issues 2-3 days after reboot. Sound/mouse/PC very Choppy - tcpip.sys ndis.sys NETIO.SYS

Alright, so I've tried what feels like everything. First off, I am troubleshooting for WINDOWS 7.
After I reboot, the computer functions relatively fine. Great latency, no choppyness, no matter what I do. About two to three days later, it gets incredibly bad. Specifically when browsing the internet using any browser. The audio becomes terribly choppy
as the mouse lags across the screen. Running LatencyMon, I see tcpip.sys is always at the top. This issue only seems to happen the most when internet activity usage is high. Also, ndis.sys is always up there too, as well as NETIO.SYS
Any help would be so greatly appreciated!! I run a small web server from this PC, so this is quite critical for me. It never used to happen until I recently began getting Pool_corruption blue screens, later to be discovered they were caused by my GIGABYTE
motherboards utility driver files, which I took care of.
I haven't really made any changes to my PC, besides several driver updates in attempt to resolve this. I have since updated my BIOS to the latest version. I even tried using Auslogics Boost Speed to improve the TCP settings based on on my 50mbps internet
speed. Nothing clears the lag, but a reboot, which is temporary. I used to run this PC for up to two weeks before I rebooted, no issues.

CONCLUSION
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing
for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS
setup. Check for BIOS updates.

Hello and thank you for the reply!
While I am waiting for the issue to start up again, I'd just like to cover some things you mentioned in your post. :)
I only updated the bios because I was originally experiencing these issues. It was a method to hopefully resolve them, which did not work. I was very careful, and the process was a success. I updated to the most recent recommended driver for my motherboard
from the manufacturers.
As for Auslogics Boost Speed, it is not running on my computer, as it is a piece of software I only have used to clean junk files (cache/temp) for a very long time now with no issue. I have also tried updating all of my drivers with success, however that
did not solve the issue either. I even rolled back my network card driver just in case with no luck.
I have not thought of disabling my audio driver yet, being how it effects far more than just my audio when it happens. My mouse is jittery/laggy as well when no sound is playing. But other tests have shown that it may be a network issue. Next time it happens
I'll temporary disable my network drivers to see if that causes the issue to clear up.
I will be sure to mark answers which help appropriately. Thanks again! I should return with the information requested from Zigzag's wiki within 2 days of on-time, when this happens again.

BUG with Memory CAS-Latency with MSI i848P Neo-LS BIOS

I have a bug with MSI i848P Neo-LS BIOS. I try many MSI i848P with same trouble : the CAS Latency is always set to 2.0 even if the memory is CAS Latency 2.5.
It doesn't depend on PSU or others things (graphics card,...).
Try with Pentium 4C 2.6 or 2.8
But I have just one brand of memory (but many different sticks). Chips reference are VT56DD32M8PC-5 (256 or 512 Mb). This memory are reference as Cas Latency 2.5
If I set memory timings on SPD or manual : same result !!!
If I set memory speed on AUTO or 400 MHz : same result !!!
If I set other timings, then they are save correctly (ie : RAS# precharge set to 3 or 4).
I check timings with latest version of Memtest86+ V1.0 : http://www.memtest.org/
and of course, I get many errors.
The same memory tested on others mobo, give good results.
I try Windows XP installation and I get.... blue screens.
With some memory sticks : I have this message "memory timing too tighly",
if I press F1 to continue: then I get a memory cas latency of 2.5 with memtest86+ and then no error.
I try BIOS revision 1.0 (default) and 1.2: same result !!!
So, as I said before, I think this is a bug with the BIOS. I agree that a BIOS cannot detect correctly all kind of memory, but if you set memory timings manualy, then it must be set as you want ! ?
Any idea...
Thanks

H0 Alex,
You are correct.I have the same problem with my 875p neo lsr on bios 1.9. TH0S 0S B0OS BUG.but everyone says your psu is not enough or your rams isnt on the MSI Memory Compatability List.
why all of rams I try give same result?
MS0 boards works only with 10 or 20 ram.you don't say customer why you use this rams?
why in asus boards many os these rams working properly.This rams isnt on the MSI Memory Compatability List.but working.I try many no name rams and results are very good in all of the tests.
In my opinion MS0 bioses doesnt work good enough.
You don't drive a car.Car Drives you.
