MSI-8340 cd writer speed problem

I have just got an MSI cd writer 8340 - yet i am having a problem with the speed - as it is not burning 40X cd with 40X but only with 32X also i have a cd rewritable 10X speed and it is only allowing me to burn at 8X
I used different cd writing software and still had the same thing - i used nero and clone cd
I have firmware 100d - should i update
Does anyone has the same problem?
Please help me
Also on the msi product archive there is no MSI-8340 writer there is an ms-8340A is that the same thing

Paul:
Please tell us your Specs
May be you have not too much Ram to run XP, let's say 256 MB or less? Does the recordable cds support that speed?
What's the recording software you are using?
Regards

DR8-A (150D) Write speed problems under linux

Hi all,
I would appreciate a response from MSI , perhaps a modification to the next fimware release.
Linux applications have difficulty changing the DVD +-R write speed due to an alleged incorrect response from the DR8-A firmware. See example, from growisofs author; http://lists.debian.org/cdwrite/2004/05/msg00192.html

So-far I have been unable to select a speed for the unit other than the maximum speed of the media. Apparently, when the burning program asks for the current writer speed setting, the media speed is returned.
While I am impressed with the advertised versatility of the unit, i am disappointed in the number of "hangups" when unsuitable media is inserted. The only way to return the unit to service is to completely turn off the power, a re-start is insufficient. (Linux or Windows)
Thanks
Noel

Post your computer's specification.
And what kind of Linux are u using, i.e. what OS? Also try other burning software in Linux.
Note: I know how to use Linux myself.

Msi 990fx gd65 cpu speed problem p2x4 965

Hi im new here this is my first topic.
I buy a Msi 990fx gd65 board my problem is everytime when boot up the pc the cpu freq. is 800mhz (4x200) i disable every power saving option and cool n quit thing, i must every time in click bios to adjust the frequency to 17x200 and restart to be enabled, i have a latest bios 19.9 a cpu is p2x4 965 be rev c3, 2x4gbddr 1600 Msi gtx 580 twin frozer and a chieftec psu 600w.
The control center is installed and a click bios to.
Thanks for a help and sorry for a bad english writing when exist.

Gtx 980 MSi Gaming App Clock speed problem

Hello guys, I've a problem with my GPU's clock speed.
I've MSI Z97-Gaming 5 motherboard, and MSI gtx 980 4g twinfrozr so both of this hardware uses the MSI gaming APP.
But the thing is when i pick Gaming Mode or OC Mode it works well for my CPU BUT! not for my GPU, it always at 962Mhz it barely goes to 1190 and comes right back.
When i check the site it says:
1216MHz Core (Boost Clock:1317MHz) (OC Mode)
1190MHz Core (Boost Clock:1291MHz) (Gaming Mode)
1127MHz Core (Boost Clock:1216MHz) (Silent Mode)
you can see the actual core speeds but 962 mhz is not even there ?
if anybody has an idea I'd really appreciate that.

OK the problem was solved by loading an older version of the MSI gaming App from the Dvd . Now it is selected as " let the 3d app decide " at the nvidia control panel, and when im in game it goes up to 1368 Mhz and when im on desktop it goes down to 135 Mhz .

K9N2 Sli Platinum + SSD OCZ Vertex 3 = Slow Speed Problem [PARTIALLY SOLVED]

Hey folks,
I have a problem with my new SSD. I only get sequential reads of 140MB/s and writes of 114MB/s.
I think it is a driver related issue. I once got faster SATA2-like speeds but cannot reproduce the system settings again... Everything back to SATA1-like speeds after reboot.
First my pc specs:
MSI K9N2 Sli Platinum, BIOS v3.9
- 6 SATAII ports by nForce 750a SLI
- 2 ESATA (External-SATA) ports (back panel) by JMB363
- Supports storage and data transfers at up to 3 Gb/s
AMD Phenom II 965 Black
Patriot PV224G8500ELKB Viper II Series DDR2 4GB (2 x 2GB, CL5 PC-8500/1066MHz)
SSD SATAIII OCZ Vertex 3, 120GB, FW v2.11
LG Internal BlueRay BH10LS30
Windows 7 Ultimate x64
I only get very slow speeds with the SSD. I tried so many things that I am getting very frustrated now, I am even thinking about getting a new board and ram just to get the SSD up to speed...
1)
I installed Win7 first with all the default settings in Windows Setup from DVD. Default "IDE ATA/ATAPI controllers" driver was "Standard AHCI1.0 Serial ATA Controller".
SSD was connected to SATA1-port, On-Chip Sata Controller AHCI enabled in BIOS, Extra RAID/IDE Controller disabled.
All fine, but whichever benchmark I used (AS SSD, HD Tune Pro, Atto Disk Benchmark, CrystalDiskMark; other tools used: DriveControllerInfo, AIDA64/Everest, CrystalDiskInfo ) I got e.g. 140MB/s Read and 114MB/s Write sequentially (CrystalDiskmark, similar with random data AND only zeros ).
Trim working (it seems) with AHCI driver. I also changed to nvstor64 driver (nforce driver setup 15.56), with is marginally faster but not what you would expect from a SATAIII drive on SATAII controller.
2)
I installed Win7 using "diskpart" (Shift-F10) during disk setup, setting a cluster size of 64k instead of default. No real change.
3)
After reinstall of Win7 x64 (again...), I changed from SATA1 port to SATA6 port, also enabled Extra Raid/IDE controller set to AHCI as well.
Nothing changed. With all settings to default in Windows (ahci default driver), I then manually updated the ahci to nvstore64 driver in Device Management, rebooted.
Then a minute later after reboot I got the following Sequential speeds with CrystalDiskMark:
273MB/s read and 137MB/s write (random data) + 274MB/s read and 220MB/s write (with zeros) !!!
While I ran this benchmark Windows came up with a message: "You must restart your computer to apply these changes - Restart Now/Restart Later".
After the previos reboot, when I changed manually from AHCI to NVSTORE, I had changed nothing in the current session, apart from running CrystalDiskMark.
I did reboot and I was back to the slow SSD speeds again = 140/114 MB/s...
4)
I have tried every possible combination of mainboard SATA ports, drivers changing with nvidia setup/manually, deleting and disabling controllers (incl BSOD and startup repair :D ), chaning bios settings around, but I just cannot get back the faster speeds
There is never any change in speed, whether I use ahci or nvstore64, whichever benchmark I use, whether random or zeros...
5)
Could the SSD be broken, something internally preventing it from faster speeds (with this one random exception)?
Could it be that my K9N2 SataPorts only allows for / reduced to SATA1 speeds?
Am I missing something with the driver setup?
Do I need additional drivers for the extra JMicron Controller when using SataPorts 5/6 ?
I have no other mainboard to test this with...
Please guys, I am going to jump out of the window if I can't fix it... :(
Thanks, Mike

Hey guys - problem 'solved':
I tested the OCZ SSD Vertex 3 120GB with following sata3 controller card http://www.lycom.com.tw/PE-115H.htm.
The card itself works immediately (needs at least PCIe x4 slot, will work slower otherwise but still faster than the OCZ SSD @sata1 with nvidia chipset).
There is some raid setup, doesn't apply to me, the boot even with the card is really only a few seconds longer and not annoying at all. Windows (7 x64) needed a driver, supplied on CD (which is cheap and making noise like h**l). The card works w/o the driver but doesn't harm to install it...
Also, just to clarify, this sata controller card did not need any specific setup at all. Just put it in, plug in sata cable (I use akasa sata3-rated), maybe change boot device in BIOS (I didn't even have to), done - booting Windows as usual.

Speed is much better than before with nvidia chipset 750a SLI controller: sata1 (sata2 whenever it randomly worked):

http://img13.imageshack.us/img13/6258/cdmahci0x0sata6contnv64.png
Final thoughts:
Well, I am happy with the SSD speed now (PCIe limited to 5Gbps). However, I had to spent quite some time to get it working on my sata2-cabable mainboard. Finally, I had to buy a extra controller card to get it working reliably at speeds faster than sata1. There is hardly any useful information on why this problem occurs with (older) nvidia chipsets and OCZ (sata3) SSDs. I still think that OCZ must know about this problem, but regards this issue as low priority, while at the same time not planning on giving up on sales to people with nvidia chipsets. Maybe OCZ should just make a big sticker on the box the drives come in with something like "Does/Might not work with nvidia chipsets, please use third-party sata controller card or different SSD manufacturer". But then none of these potential customers would buy OCZ SSDs...
I will keep the sata3 controller, anyway handy to have, but return the OCZ Vertex 3 120GB and replace it with a SSD from a different manufacturer (Corsair Force GT, Patriot and OWC are not that great to get around here). The benchmarks for most people will not achieve the maximum advertised OCZ speeds anyway, so why not go with a brand that allows for some plug'n'play with some customer support.
Hope this post helps others like me with their nvidia chipset + sata1 speed problem
Cheers, Mike

Something has to give. This is rediculous...SATA write speed.

I've been asking and asking but haven't found anyone with the knowledge to help yet. My system is based on a P6N SLI-FI mobo and here are the stats:
P6N SLI-FI BIOS v2.0
P4 650
2 - 1Gb modules of DDR2-667
2 - 169Gb 3Gb/s 7200RPM SATA drives in RAID 0 striped
1 - 48x DVD optical drive
WinXP Home w/sp2
Here's the trouble:
The write speed to the drives is incredibly slow. Not to mention it take over 2 minutes to go into hibernation but, I tested the transfer speed by installing a 628Mb game. It took about 15 minutes to copy the files of that game disc to the HDDs.
Wanting to dig deeper I installed the 628Mb game onto another, much slower system. Here's the stats for the slower system:
Asus A7N8X-X mobo
2 - 512Mb DDR-400
1- 80Gb 7200 RPM PATA drive
1- 48x DVD optical drive
WinXP Home w/sp2
It took about 3 minutes to copy the 628Mb game disc to the HDD on this slower system.
I've looked in the BIOS of the MSI board and can't find anything unusual but I'm not an expert, just a novice.
The MSI system goes into hibernation very, very slowly and write files very very slowly. Something is amiss.
I'd appreciate any help I can get.
Thank you

Are you sure it isn't the DVD drive reading slow?
As for hibernation, the more physical memory you have, the longer it takes to write it to the drive. Also check and make sure there is not a program interfering with hibernation, end all the processes you are able to in task manager and see if that helps. Is there a particular reason you want it to hibernate vs. standby?
The Moan Guide is a way to say we need more info:
P6N SLI-FI BIOS v2.0
P4 650
2 - 1Gb modules of DDR2-667 What brand/model?
2 - 169Gb 3Gb/s 7200RPM SATA drives in RAID 0 striped What make/model?
1 - 48x DVD optical drive Brand, Model, IDE/SATA?
WinXP Home w/sp2
Power Supply? What are the rail Amps?
Video Card?
PSU is a Corsair HX620W. +12v Rail amp are 18, 18 and 18. Videocard is an EVGA GeForce 7800GT CO Non-SLI mode.
Reinstalled WinXP, put back the 1Gb of Ballistix (DDR2-533 x 4) had 2Gb G.Skill (DDR2-667 x 2).
Hibernation still takes almost 3 min. System hasn't crashed yet but I haven't yet fully installed all of the programs I use, which never cause problems on any other PC I've ever used them on.
I'm in the process of downloading and installing all of the Windows updates. After that I'll install the latest drivers for this mobo. Then I'll install PowerDVD 4. I bet it'll crash then. The previous state of this MSI system seemed to hate PDVD 4.

*TERRIBLE* "Write" speeds w/2x Samsung 850 Pro Internal SSD (RAID-0).. HELP! ( pics)

[url]http://imgur.com/a/5p05u[/url]
Hello.. I was really hoping somebody could help me out with this, as I'm pretty much starting to lose hope..
I've attached as many relative screenshots as possible, to make it easier to quickly see what's going on.
I've got [b]2x brand-new, Samsung 850 Pro 512GB SSD's[/b] installed inside my MacBook Pro.. [b]One inside the hard-drive bay, and one inside the Optical Bay[/b] (SuperDrive Bay), using an OWC Data-Doubler..
I've got these drives configured using Disk Utility, into a RAID-0 striped configuration..
[u]The drives are rated @:[/u]
[b]Sequential Read:[/b] 550MB/s
[b]Sequential Write:[/b] 520MB/s
[img]http://i.imgur.com/sY83PX0.png[/img]
So "theoretically", I should be achieving approximately close to double these speeds (since that's the basis behind RAID-0 configurations)
[u]Both SSD's are connected internally via SATA-III (6Gigabit Link + 6Gigabit Negotiated Link Speed)[/u].. Both in the hard-drive bay, as well as in the Optical Bay (confirmed in pictures)..
I'm getting [b]*EXCELLENT* "Read" Speeds[/b], yet [b]*HORRIBLE* "Write Speeds[/b].. to the point that the RAID-0 software configuration is not even achieving *near* the "Write" Speed of even one of these drives.. let alone 2 of these drives in RAID-0..
[img]http://i.imgur.com/0jw9Z7l.png[/img]
I've tried contacting Samsung directly regarding this issue, but since they don't exactly get along with Apple, and even more-so, dislike anything that has to do with "RAID" configurations, I was left with practically no help on that end..
I've tried contacting Apple, who said that I'm pretty much on my own, in terms of support, since [i]they[/i] don't exactly get along with Samsung either.. and don't provide much of any support whatsoever, when it comes to third-party, hardware components that are not upgraded directly through Apple themselves.. (aka no support for user-end personal upgrades)
Both of these drives are [b]*Brand New*[/b] directly out-of-the-box, shipped from Amazon, as "new, un-opened" items..

I apologize in advance if there's a lot of pictures to go through, however, I know how much of a pain in the *** it can be to troubleshoot these sort of problems, let alone, try to help somebody else troubleshoot these problems while not physically being there in person.. I tried to provide the [b]most comprehensive[/b] troubleshooting steps I've taken thus far, as to hopefully make this thread as fruitful as possible, and eliminate any unnecessary steps that have already been taken..
I've tried re-formatting and re-installing OSX Mavericks 10.9.5 several times now, hoping that maybe one of them would allow the RAID formation to work as it should, yet none so far have proven successful..
If you have any time to look through and read this thread, I can't tell you how appreciative I'd be for your help and any advice possible that you can give me.. I do large amounts of audio processing, producing, along with many other taxing system processes, so I'd really like to get this RAID-0 configuration working as it should be..
Please do not waste your time by bashing RAID-0 or writing an unhelpful, opinionated comment that does not move this process forward.. I understand the risks of RAID-0, I run [b]daily backups[/b], as well as having an Apple Time Capsule running in full-force, all day long.. My data is well backed-up, and I understand the risks.
If anybody has dealt with this sort of issue before, please, give me any advice that you can.. I tried to put in the most effort possible with uploading and embedding all of these photos, as to not waste your time and to hopefully make this troubleshooting process as smooth as possible
Thank you all so much in advance! :apple:

DVD dual layer write speed?

Anybody know what the maximum write speed of the Superdrive is, for dual-layer DVDs?
I have a late 2011 MacBook Pro 15" and I want to buy some blank DL DVDs. I'm looking at Verabtim DVD+R DL blank media. They offer both 2.4X and 8X speeds. I've read that the 8X disks - which are more expensive, roughly 15 for the price of 20 of the slower disks - can be a problem for older drives that don't support that speed.
I already know that my Superdrive will write at 8X or more for a single-layer disk.

"Be sure to take full advantage of:
About this Mac > ( More Info ) > Disk Burning ..."
Yup, this showed me that my 8X (single layer) disk could in fact be burned at 8X, but without any DL disks for testing, ATM doesn't tell you anything about burning speeds.
Thanks for the confirmation that I do NOT want to buy the 8X disks. I've gone ahead and ordered the 2.4X Verbatim disks. I also saw some labeled as 2.4-6X, and I suppose those would work with my 4X drive.

Athalon XP clock speed problem

I hav just installed a K7N2 Delta Mobo in my system, but I'm having CPU clock speed problems.
The Bios and the Infoview program both state that the CPU clock is running at 1105 Mhz. I am sure this should be 1533 Mhz for an 1800xp.
I updated the bios using MSI live update, and the first time I booted the system, the bios displayed the speed as 1533 Mhz, but on every subsequent boot up it is back down to 1105 Mhz again.
How can I get my processor to run at the correct speed?
Thanks

Sorry, just realised I have posted in the wrong forum.
Please forgive me

All of a sudden only 4x and 8 x write speeds are available when building DVD

I have been using Encore successfully for several months to burn my indie film onto DVD for grant proposals . I found if I used a 1x write speed my DVDs played on most DVD players and computers.
As of yesterday all of a sudden and for no reason (I made no chances to my computer that day) the only write speeds available to choose from when building a DVD were 4x and 8X and when I burn a DVD at these speeds it does not play well enough to watch.
I rebooted my computer and even tried restored my computer to the states it was in a few days ago but nothing worked...in terms of getting back the broader choice of write speeds.
I called adobe Technical support and they said that I would need to pay for support to fix the problem...does any one know how I can fix this without having to pay adobe lots of money for tech support
Kathleen

a) The drive's lifecycle counter has kicked in. If so, it would prevent non-optimal software-controlled modes and only allow burning at its native speeds to extend life expectancy.
b) Some other tool that accessed the disc drive and reset its config data.
c) Windows itself has for some reason initiated a new hardware detection and reset driver config.
In any case, it would seem that you will have to re-initialize manually. Remove the drive from your device manager and have Windows scan for new hardware. Do so with admin privileges. Windows should automatically re-install the required drivers, but with default settings. Also check this: http://support.microsoft.com/kb/314060. even though Encore doesn't give any error, the case listed under 1) may apply - if the driver is not installed correctly, it would report incorrect burn speeds.

Java Audio Metronome | Timing and Speed Problems

Hi all,
I’m starting to work on a music/metronome application in Java and I’m running into some problems with the timing and speed.
For testing purposes I’m trying to play two sine wave tones at the same time at regular intervals, but instead they play in sync for a few beats and then slightly out of sync for a few beats and then back in sync again for a few beats.
From researching good metronome programming, I found that Thread.sleep() is horrible for timing, so I completely avoided that and went with checking System.nanoTime() to determine when the sounds should play.
I’m using AudioSystem’s SourceDataLine for my audio player and I’m using a thread for each tone that constantly polls System.nanoTime() in order to determine when the sound should play. I create a new SourceDataLine and delete the previous one each time a sound plays, because the volume fluctuates if I leave the line open and keep playing sounds on the same line. I create the player before polling nanoTime() so that the player is already created and all it has to do is play the sound when it is time.
In theory this seemed like a good method for getting each sound to play on time, but it’s not working correctly.
At the moment this is just a simple test in Java, but my goal is to create my app on mobile devices (Android, iOS, Windows Phone, etc)...however my current method isn’t even keeping perfect time on a PC, so I’m worried that certain mobile devices with limited resources will have even more timing problems. I will also be adding more sounds to it to create more complex rhythms, so it needs to be able to handle multiple sounds going simultaneously without sounds lagging.
Another problem I’m having is that the max tempo is controlled by the length of the tone since the tones don’t overlap each other. I tried adding additional threads so that every tone that played would get its own thread...but that really screwed up the timing, so I took it out. I would like to have a way to overlap the previous sound to allow for much higher tempos.
I posted this question on StackOverflow where I got one reply and my response back explains why I went this direction instead of preloading a larger buffer (which is what they recommended). In short, I did try the buffer method first, but I want to also update a “beat counter” visual display and there was no way to know when the hardware was actually playing the sounds from the buffer. I mentioned that on StackOverflow and I also asked a couple more questions regarding the buffer method, but I haven’t received any more responses.
http://stackoverflow.com/questions/24110247/java-audio-metronome-timing-and-speed-problems
Any help getting these timing and speed issues straightened out would be greatly appreciated! Thanks.

Thanks but you have never posted reply s0lutions before ?? And F 4 is definitely not 10 times faster as stated before I upgraded !!

What is the Read/Write speed for a 250gb Serial ATA hard drive?

Hello. I've been having some problems via my Mac (Kernel panic at start up) and is thinking wether or not it is the hard drive.
Does anyone know what the Write speed is for the specified hard drive. I'm currently getting about 5 mbps and that feels a bit slow
I'm on a Macbook Pro mid 2009 model.
Thanks in advance
Ashley.

I haven't got the logs. I had to reinstall everything in order to get it to start up (Couldn't find ACPI?)
And I'm only asking because it seems like my laptop HD is running slow. Is it normally about 5mbps for a 5400rpm HDD?

[Solved]Variable read/write speed with WD Passport 1 TB external drive

I have this drive connected to my Arch Linux box. Whenever I transfer large files (I use it to backup) the write speed drops from 30M/s to sometimes a few KB/s and then speeds up again ! This drive is connected via an USB 2.0 port with a specific cable which is 2.0 at one end (to connect to my motherboard) and 3.0 at the other end (to connect to the drive). Could this be related to the kernel SES driver which is used (buffer problem maybe)?
This speed problem is that serious that backups take very long and become almost not feasable.
Thanks in advance

Jason,
this drive has 3 use cases (my PC is dual boot Arch / Windows Vista) :
1) Backup my PC linux box using a rsync front end (luckybackup) here source and target are ext4 in target always and source is either ext4 or lvm on raid.
2) Backup of my PC Windows Vista using an own written script which uses ntfsclone where source and target are ntfs.
3) Backup of my Windows 7 laptop
The problem is that I have performance issues in scenario's 1 & 2 (but not always) and never in case 3. I think this might finally be hardware related ...
Just before writing this post I connected the drive and it didn't even appear in my file manager (nemo under cinnamon 2.0). So I ran a journalctl and here is the outcome :

Something also worth knowing : the drive is know for being a heavy power drain on the usb 2.0 port (it does not have an external power connection and gets its power only via usb) . So I bought a specific cable with 3.0 at one end and 2 usb 2.0 at the other end : one for transferring data and one for power.

Toshiba SSD vs Samsung SSD and inconsistent read/write speeds

I've heard that some of the 2011 Airs are shipping with Toshiba SSDs where others have the Samsung SSDs. Apparently the Toshiba ones are considerably slower and are more likely to be in the 13" models where the Samsung SSDs are more likely to be in the 11" models. I was curious if anyone out there has an 11" model with the 256GB option, and if so, which SSD did you get in yours? See here: http://9to5mac.com/2011/07/25/2011-macbook-air-ssd-speeds-are-not-consistent/#mo re-85182
Thanks

I'm really disappointed, considering I spent $1200 on a portable laptop, I expect it to be pretty much perfect, and it's a let down knowing I didn't get what a lot of other people paying the same price might be getting. Anything on this Apple?
Are you looking to get a response from Apple here? If so you're going to be left wanting. This is a user-to-user discussion forum, if you wish to communicate with Apple you'll need to get on the phone with AppleCare or bring it into the store.
You can also return the machine and buy a new one, it's a 50/50 chance.
I have the Toshiba drive in my 13" MBA with the 128GB SSD. A co-worker has the same model machine with a Samsung drive.
As Apple doesn't promise a minimum SSD read/write speed I don't really see any justification for them to offer an exchange on a unit unless it's defective (which this would not be considered defective in their eyes). Thus my recommendation for the return. The other problem is there's no discernible markings on the outside of the box that indicate which drive is in the machine, plus Apple doesn't let you "try before you buy."
Even given the slower Toshiba speeds, I'd be really curious to see someone max out the capabilities of either drive.

Hp pen drive v220w read/write speed in about 50 kbps

My 16 gb hp pen drive v220w which was giving a read speed of about 30 mbps and write speed of about 8 mbps became slow all of a sudden ......
Now it is giving read and write speed of about 50-100 kbps . It also takes a long time to format or to delete data.
It is showing 14.9gb of usable space and no errors were found when i tested it....but still its speed is quite slow....
Please somebody help me!
