DPC Latency issue, need to update BIOS?

I'm into recording music and latency is of great importance. I did a DPC latency check and noticed I was getting some major peaks, constantly. I tried everything, removing sound card, disabling drivers, etc, etc and nothing works. Then I did a google search and found this: https://forum-en.msi.com/index.php?topic=125206.0
I have...
Model name: 7519 v1.0
M/B ERP Version: 06
I have NEVER flashed BIOS before and have no idea how to do it. I don't even have a floppy drive. I really need to fix this latency issue though, otherwise I will have to buy a new computer :(
Can someone help me? I sent en inquiry to the support, but did not get a reply.
Thank you.

What is the model name of your mainboard? There are many MS-7519 mainboards with different PCB and ERP numbers (your ERP number is incomplete, there must be three digits):
http://eu.msi.com/service/search/?kw=7519&type=product
The best way to approach this, is to check your current BIOS Version as displayed on the P.O.S.T. Status Screen:
Write down the full BIOS ID String as it appears in the red box in the example picture. When we know the BIOS Version, it is possible to check whether or not there is Latency Fix for your board out there or not.
Have a look here and make yourself familiar with our MSI HQ Forum USB Flashing Tool: >>Use the MSI HQ Forum USB flasher<<.

*Solved* MSI P43 Neo-F DPC Latency Issue - Latest BIOS Fix

Hi, I'd like to avail of the latest BIOS fix for the DPC latency problem on my MSI P43 Neo-F (MS-7519) 1.0.
I'm currently using BIOS 1.9, I haven't flashed to 1.A yet. Does 1.A include a fix or is there another BIOS that's as up-to-date as 1.9 or 1.A that would have the fix, with any links to download? I'm thinking along the lines of the A7519ICI.1xx series, whatever is the latest.
Thanks in advance.
EDIT: I have contacted MSI at http://ocss.msi.com.tw/
I don't suppose there is any links to the latest A7519ICI.1xx BIOS that I can avail of outside of the private MSI FTP server?

Thanks all for the advice.
OK, so here's the story. I couldn't relax with those voltages showing up as they were, so I flashed my BIOS to A7519IMS.1A0 (1.A), which is the latest public release for the P43 Neo-F. I was previously on A7519IMS.190 (1.9) before today.
When I flashed to A7519ICI.104, I noticed the version number was actually 1.10B4 (which I'm guessing can actually be expressed as 1.AB4 - a beta version for the latest public release, 1.A). The flash to A7519ICI.104 solved the DPC Latency issue, as when I used A7519IMS.190 (1.9) it was spiking.
There is a happy ending. The flash to A7519IMS.1A0 (1.A) has also shown no spikes in the DPC Latency test. It seems the fix must be present in the latest public release BIOS for the P43 Neo-F after-all!
This screen-shot was taken just a moment ago, proof that the issue has been resolved without a modified BIOS:
Hope this helps anyone else out who is using the same motherboard and experiencing the same issues. Just get the latest public BIOS. No hassle!
http://www.msi.com/index.php?func=downloaddetail&type=bios&maincat_no=1&prod_no=1484
Please make sure that your motherboard is in-fact the MSI P43 Neo-F (MS-7519) before you flash the BIOS with any of the ones contained within the link above

VLC audio problems on T400 - DPC Latency Issue?

Hi Folks,
When I try to use VLC player to play any video on my T400, I get audio stutters and other strange effects. I'm wondering if it might have to do with all the audio DPC Latency issues this model has had. Does anyone else have these issues? Windows media player seems to work just fine, by the way. DPC Latency is high when either program is playing, but remains high when VLC has paused playback (whereas windows media player doesn't induce high DPC Latency when paused).
I've tried tweaking the buffer of VLC player, and a million other things, but nothing seems to help. Hence my suspicion of DPC Latency issues.
Thanks,
Allie

Serious DPC latency issues with Xbox One Controller

Not sure if this is the right forum for it, but I'm hoping...
I recently got an Xbox One Controller (with a USB cable for Windows), and installed the x64 drivers for them. I've been using it for a while with no problem, however I recently had to reinstall Windows 7 due to an NVidia driver issue. I am now seeing some
issues with certain games, notably Elite Dangerous and Lord of the Rings Online (which doesn't even use a controller) while my Xbox One controller is plugged in. Terrible lag, sound cutting out. I used DPC latency checker and found that it was spiking bad.
Using LatencyMon I found that USBport.sys was the culprit. I unplugged the Xbox One controller and it was gone.
Here's the catch, I know it's not the USB port or an IRQ issue because if I plug in my Thrustmaster T-Flight HOTAS X to the same port, using the same IRQ, etc. I do not experience any issues. This is related ONLY to the Xbox One controller. Why would the
One controller cause this, and is there anything I can do to fix it? I have looked everywhere.
My PC specs are:
Windows 7 x64 Ultimate
Intel i7-2600k OC @ 4.2ghz
16gb DDR3 ram @ 1600mhz
Nvidia GTX 770 OC 4gb
MSI z68a-gd65(g3) motherboard
HT Omega Claro Halo soundcard
Any help would be appreciated, Thanks!
Edit: I actually had to disable HPET in my bios to even run LOTRO or it would crash my PC, that was until I found out it was the One controller that was causing it.

Hi Marcus,
Considering this issue occurred after reinstalling the machine, please ensure your system is update to date.
Since you have caught the culprit with the LatencyMon, have you tried to update the USB controller or reinstall the USB controller to have a check .
Apart from this ,is the One Controller Driver a manufacturer driver ? If it isn`t official driver ,I recommend you to download the driver from the manufacturer website.
Best regards
Hi MeipoXu,
Thanks for the reply. :) I've been scratching my head with this issue.
I've got all updates done and I used the official x64 Xbox One controller driver from Microsoft. Also have tried update, reinstall the USB controllers under device manager, even tried replacing usbport.sys with a friends copy but they were identical.
What's interesting to note is that this doesn't happen in all games, only certain ones. Since I haven't played either of those games I mentioned after I got the One controller and before the reinstall, I have no clue if it had anything to do with the reinstall
or if it's just an issue with the controller. I posted on those games forums and did not get any replies.
I did notice a lower DPC latency when I plugged the controller into my third-party USB 3.0 controller ports, but it was still spiking up into the reds consistently. I also went as far as to unplug ALL other USB devices, including my mouse and keyboard to
see if that made a difference, and it didn't. Nothing else does this, only the One controller. I'm at a loss. =/

DPC Latency issues using wired or wireless adapters

I am experiencing terrible audio popping and skips on my HP Desktop when playing iTunes music or watching a video streamed from the internet. I used the DPC Latency Checker and discovered that both the wired LAN adapter and wireless adapter were causing the problem. When I go into Device Manager and disable the drivers for both adapters the problem goes away. When I enable either driver the problem comes back. It's definitely being caused by the network adapter drivers. I've enabled/disabled all the other drivers on my PC and its pointing to the network adapters. But the network adapters are from different manufacturers. Realtek for the wired and Ralink for the wireless. I've updated both drivers and it didn't fix the problem. My only conclusion is both adapters must be connected to the motherboard and something within the mohterboard is causing the problem. If anybody as some feedback it would be greatly apprecaited. I don't want to buy another PC. But I can't seem to solve the problem.

Hello , I have read your post on how your desktop computer is experiencing an audio popping and skipping sound when playing iTunes music or streamed videos, and I would be happy to assist you in this matter! Since you have already re-installed the audio drivers for your computer, I recommend returning your system back to a previous restore point before the issue occurred. This can be done by following the steps in this document on Using Microsoft System Restore (Windows 7).
Should the problem continue, I suggest performing a backup and recovery of your operating system. This can be done by following the steps in this resource on Backing Up Your Files (Windows 7), as well as Performing an HP system recovery (Windows 7). This should return your system back to factory defaults.

Equium A110-276: Do I need to update BIOS when Vista was installed?

I do know where to post this...
"I have clean installation of Windows Vista on my Equium A110-276. Do I need to update the BIOS or not? Does Updating BIOS Compulsory/mandatory?

Hi
It seems Toshiba has published a special version of BIOS for Windows Vista.
If you want you can check it on the Toshiba driver page.
But if your Vista runs correctly on the notebook with previous BIOS version you dont need to update the BIOS.
I would recommend updating the BIOS if any strange operational behavior will appear.

I see this has been an issue with other MSI P45 MB's. This system is purpose-built for recording, the spikes negatively affect my ability to record at low buffer settings. Otherwise, everything is perfect-very nice MB. Here's hoping they have a custom BIOS to fix this.

Is this a beta or a public BIOS?
When did you submit the request? (nothing happened with mine for the P45 Neo3 latency issue yet)
I submitted my issue to customer service (http://ocss.msi.com.tw/) on 9FEB. I received a reply 10FEB. The BIOS file has been on their ftp site since 23DEC08. It is not the public BIOS (1.6) available for download on MSI web site.
There is a BIOS I believe is for for your board with the same file name type as the one I used on the ftp site. Mine was A7513ICI.101. There is an A7514ICI.101 here: ftp://ftp.msi.com.tw/BIOS/7514/. Up to you if you want to chance it.
DL USBoot.rar from here: ftp://ftp.msi.com.tw/Tools/ follow directions to make bootable USB flash drive. I DL AFUWIN from here: http://www.ami.com/support/bios.cfm and found the newest version of AFUDOS.exe in one of the folders and put that on my bootable USB stick. The version MSI provided would not work for me. Change boot order to USB 2.0 first. Once booted on USB stick syntax I used was: afudos /i(BIOS filename) -no parenthesis when entering in DOS - at first it gave me an error but then it quickly proceeded to execute. I'd back up your current BIOS just in case.
Good luck.

Need to update Bios ? n100 Model

Can anyone tell me how to update the Bios on my computer.
I have tried to load the new Bios according to the Lenovo site but it will not take.
Computer is the 3000 N100 0768 A49
I have downloaded it to the desktop, then run the setup with the wizard then it is telling me it made a file.
After checking the Bios it has never changed and is the same old 63ET62WW V1.08 version.
Also, can you tell me how to eliminate the need for a password on Vista Business. I do not want to log on every time it boots up or goes into sleep mode.
Thank you
CBat

You need to go to the folder created by the downloaded program and run the bios update.
Read the Installation Instructions on THIS page!
Always use caution when updating bios.
As to password, go to Control Panel, Users and Groups and change your
password to a blank. (delete existing password.)
And Screensaver settings, uncheck Require a Password...

Qosmio F50 - Need to update BIOS in order of installing Win7-64bit

Dear community,
I plan to update to Windows 7 64 bit. My notebook is Toshiba Qosmio F50-10M with a preinstalled VISTA32bit.
Is there a need to update the BIOS prior installing the new OS? I read that there is a BIOS update f?¼r VISTA64bit available but none I discovered for Win7 64bit.
Can you give a clue?
I am confident and glad to own such a powerful notebook but this not completed OS named VISTA is driving me nuts increasingly reading all those nice reports concerning the benefits of Windows7!
Eager to read your welcomed responses
Yours,
Starmind

Thank you for anwering Paolo!
Do I understand the right way? I shouldn´t change BIOS if I don´t encounter any problems?
But I should change the BIOS from 32 to 64 bit if I install the 64bit version of Win7? I intend to do so as I plan to use the full memory of my machine (I use VISTA32 at the moment).
I should change the BIOS prior installing Win7 as I understood as posted earlier?
Thank your for your kind assistance!

MSI P45 Neo3 DPC Latency issues

Hi guys. I'm on a MSI P45 Neo3 and so far everything's good. The only thing wrong is the high memory latencies I'm seeing in the DPC latency program + programs sometimes taking too long to load or start up etc.
My motherboard is MSI P45 Neo3 - MS-7514 V1.0
Is there any beta BIOS I can try to fix this problem for my motherboard?

My configuration:
Antec Midi Tower Sonata III Life Style ATX 500W
Arctic Processor cooler F7-PRO
Asus PCI-e Radeon HD3450 256MB Silent DVI/HDCP videocard
Intel Core 2 Duo E8400 3.00GHz 1333 6MB Boxed (C0 I think)
LG DVD-/+/RAM GH20NS10 20x/20x/12x Bulk
Logitech MX518 Optical Mouse (connected via PS/2)
Microsoft Digital Media Pro Keyboard (connected via PS/2)
MSI P45 NEO3-FR iP45 (PCB 1.0)
NEC Floppydrive 1,44MB 3,5"
OCZ 2x2GB DDR2 SDRAM PC6400 CL5.0 Platinum (in dual channel mode)
Samsung 640GB SATA300 16MB, HD642JJ (in RAID "prepared" mode)
Sweex Card Reader CR005V2 All-in-1 Intern 3,5" USB2.0
All running their latest firmware/BIOS and drivers as far as I know.
The system uses default BIOS (v1.6) settings, no overclocking at all.
Where should I start my investigation?
Disable software, drivers, or hardware?
Any suggestions on which particular item?

CPU upgrade - do I need to update bios??

I got a KT3 Ultra 2 6380E mobo with Bios V5.60 and I want to put in a AMB 2600+ Barton (333)
Do I need to update my bios to V5.70???
I dont really want to flash it unless I have to - On the MSI bios update monitor it aint clear if V5.60 supports the 'batron' 2600 as well as the normal XP 2600 cpu
And a little second point about clearning CMOS - again is this needed when upgradeing CPUs? - Can I damage anything if I aint got the correst Bios or not cleared the CMOS ??
Thanks

Z87-GD65 - Need help updating BIOS, might've bricked

I recently tried to flash/update my motherboard and I think I might've bricked it. Could somebody confirm and tell me what I should do?
I have the MSI Z87-GD65 Motherboard with an Intel i5 4690k.
My BIOS was an older version and I needed to update to support Haswell refresh. This is what happened:
I downloaded the latest BIOS update from the MSI website, extracted the files to a USB. I plugged that in and updated the BIOS through the MFLASH feature in the MSI BIOS. I updated the MSI BIOS & ME with the USB and I think the updating got to around 30-40% before the screen went black then after a little bit I got back to the BIOS menu. I checked the version and confirmed that the BIOS was updated to the latest version.
Thereafter I restarted my computer a few times and noticed that it took a little longer for the system to get to the prompt to enter "DEL" to get to BIOS compared to the first time when I booted my computer. Everything else seemed fine so I went ahead and turned off the computer again and removed the USB and replaced it with another USB to install Windows. Then as the computer booted I see an screen that shows the BIOS and ME is updating from 30%-100% then my screen went black. Now when I turn on the computer it remains black but the system powers on/fans work.
I looked up several sources to make sure I was flashing the MOBO correctly and I followed all the directions I found through MSI.
I pretty much followed the instructions here exactly:
Also I think my motherboard comes with a back-up BIOS. Is that a viable option to switch to? Are there any difference, how does it work? Also would resetting the CMOS do anything? I've been trying to figure out how I can fix the problem without having to RMA but was hoping to get some more knowledgeable advice before doing anything.
Thanks!

1. Could you elaborate on step D? How do I make sure legacy USB is enabled?
Enter bios -> Integrated periphals and check the USB settings.
Quote from: danielsuh on 29-March-15, 07:31:59
2. In step F, do I have to flip the switch to BIOS B on my motherboard then boot the computer with the USB plugged in?
You should already be at the working bios (b) so there should be no need for switching. But of course boot from the good bios.
Quote from: danielsuh on 29-March-15, 07:31:59
3. Step G: How do I switch back to the bad BIOS without restart/powering down? Do I flip the switch on the motherboard to BIOS A while the computer is still on?
Yes, you switch to the bad bios WITHOUT restarting or turning off while the machine is running.
Quote from: danielsuh on 29-March-15, 07:31:59
4. Step H: Will the directions be on a prompter once I switch to the bad BIOS or are there some directions online I'm missing?
Once you switched nothing will change for you. You will have the options from the MSI USB tool youbooted from the stick we prepared earlier. There you select the number of the flash option
Quote from: danielsuh on 29-March-15, 07:31:59
Thank you so much!
I have a few clarification questions.. just for reference this is all for a new PC I just built and doesn't have any OS installed:
5. Step I: What exactly is the ME drivers? When I originally tried to flash the drive there were two options: Update BIOS and Update BIOS & Me. So after I flash the 1B BIOS, I install windows as normal then once I get to the desktop I install the ME drivers in the link, right?
Right. What comes with the bios is the ME firmware (hardware level) but in Windows you also need to install the driver (software level). Therefor you install the driver linked after all went fine and you are back in Windows.

T410 - high DPC latency in ACPI.sys on BIOS update (leads to audio pops and crackles)

I recently updated my Thinkpad T410's BIOS because the fan wasn't working properly. The fan is working fine now, but ever since the BIOS update I've been experiencing severe audio pops and crackles. I used the tool LatencyMon to inspect, and the chief culprit seems to be ACPI.sys, with execution times as long as 10ms.
I've tried disabling all the power management options in the BIOS and changing everything to max performance. I've also tried disabling other various devices such as the network adapters, but nothing seems to help. Any idea?

Hi agrilledfish,
Is your BIOS 3.03?
I found a post on MixVibes regarding audio drops:
Audio drops/USB problems
You can try to disable ACPI.sys in device manager or uninstall and reinstall the software.

Try a hard reset, works sometimes.Disconnect all external devices first.
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall only power cord for first startup.
4-power on
