NMI: Parity Check/ Memory Parity Error -- System crash

Unfortunately even forcing fans on high constantly is sometimes not enough to prevent the error.

 

Like the poster above me has noted, even when "force fans to high speed" is set, there are still moments in which I myself have noticed tears and occasional game crashes within several of my more highly intensive graphics using games. However, in general, the issue has nearly gone away, for the *most* part I no longer get any actual entire computer crashes, simply game crashes on the off day. That being said, none of us should have to use a 3rd party program, nor run fans on high speed, nor any of this. The computer is defective, it cannot run effectively with this type of graphics card without your monitoring/ and or changing fan settings, and even that may not always be completely effective. For me though, it is *mostly* solved by running fans on high. Short of changing graphics card (not getting a new card, a DIFFERENT card), that is your best bet. Good luck..

 

Thought I would give an update. As I threatened earlier, I finally demanded that Dell replace the video card and heat sink in my computer (Inspiron E1705), since all my cooling efforts, while moderately successful, were not completely so - and also seemed to deteriorate in effectiveness with time.

As it turned out, Dell sent a technician to my workplace and replaced the graphics card (GeForce Go 7900 GS) as well as the heatsinks for both the CPU and GPU, and the RAM. Now, my operating temperatures are a little cooler (~5 degrees), but I have also stressed the GPU up to about 80 C without getting the blue screen or any graphical artifacts.

So hopefully this is a permanent fix. For those who want to do the same, it might help to mention to the telephone technician that you're sure this problem is heat-related, you get the blue screen as soon as your GPU reaches xx degrees, etc. Also mention that although it says memory parity error, you've done the full memory diagnostics and it's not the RAM. Good luck!

 

Hi all, this is indeed a great thread and as mentioned is at the top of the list if you google "NMI parity error", hence my arrival here.

My brand new XPS 1710 with a 7950gtx has just had this error. My laptop was in my office with nothing running, left for a cup of coffee and came back to the error. Interesting about heat being the suspected culprit 'cos the heating in our office in jammed on at present and it's pretty warm! I've downloaded I8fangui and have it setup, will see how we go!

Thanks to all who have contributed here.

Maybe for some people it's a heat problem, but for me it definitely wasn't. (Inspiron 6400 with X1400 graphics.)

I had the motherboard and memory chips replaced but that didn't help. Updated all the drivers and that didn't help either. Also did the Symantec system restore to the original Dell config, which didn't help.

Then had a Dell technician format my hard drive (got rid of the MediaDirect partition as well) and re-install Windows. No error since then, and that was about 3 months ago.

So try re-formatting - it's a hassle and you have to buy an external hard disk to back up all your stuff (or write it onto a DVD I suppose if you haven't got much), but should work.

 

I think you'll find a lot of people here would reformat and reinstall as the first thing they do when they get their laptop, I certainly did anyway. There seems to be many variables, finding the ghost in the machine is probably different for everyone.

I will say, after 2 NMI errors in 3 days on a brand new machine, I haven't had any since installing fangui. *touch wood*

 

its odd, i didnt get a single NMI for a while (maybe 4-6 months) after i swapped to the 'new' 7900 gs video drivers, but now i'm getting a ton of them again. whenever i boot up warcraft3 or teamfortress and play for a while, i will get the error.

heat might be a issue, heres my peak temperature according to i8kfan after playing TF2 for a while:

cpu - 80C
video card - 85c
memory - 65c
chipset - 63c
hard drive - 52c

next time i head to walmart, im going to get a can of compressed air and try to get rid of some dust. as soon as the new version of ubuntu comes out, i will reformat my computer and see if that helps.

 

I've just started having this problem with my E1705 with the Go 7900 GS.

It's crashed to the blue screen three times playing World of Warcraft and once when I came back to the laptop after leaving it alone all day. I always have the "dots" on the Dell and Windows XP load screens. I ran the Dell Diagnostics as well as BurnInTest, and both have showed multiple errors in the video memory. I've updated to system BIOS A09 and gone back to Dell's 84.69 drivers. I've tested each SODiMM individually with memtest86+ and it's not a RAM issue. Both of these were at the suggestion of Dell's techs. I just re-installed i8kfangui so I guess I'll see if it's heat related.

Is there any fix for corrupt video memory, short of a new card.

 

The dell diagnostics test should of been sufficient to warrant a new card. That will be the only way to correct the issue.

 

I called them up tonight. I always seem to get a better answer on the phone than from the chat. This tech agreed it was probably the video card but it might be the mobo as well so I'm sending it off to the depot.

 

Hi Guys,
I am a student at a laptop University and i work at the helpdesk. We've had several computers start to show up with this issue and no clue as to why its occurring. We have IBM/Lenovo R60 with 1.8 core duo processor and the ATI Mobility x1400. I'm not convinced that whats occurring is a driver related issue because i have had it occurring on one machine switch the hard drive to a identical machine and no issues. we swap the hard drive from one machine to another without any driver change or BIOS. Both are running the same BIOS version. from reading on several sites and this forum that its something related a device on a PCI bus. Ive seen several reports of people installing a new card on a pci bus and the error occurs then they remove the card and nothing happens. if anyones figured something out besides a driver or BIOS issue help would be much appreciated.

 

Hi all,

I've been suffering with the NMI parity errors for some time now. I'm running an XPS M1710, with the following system specs:

CPU: Core 2 Duo T7600
MOBO: MXG061
BIOS: A07
RAM: 2GB DDR2 (333MHz)
Graphics: Nvidia Geforce go 7900 gs

My system orginally shipped with XP, which initially had run fine with the stock wireless, having had issues with the wireless dropping out, i upgraded to a Gigabyte GN-WI01GT, which solved my wireless issues, at this point all was still fine. I decided to upgrade to Vista a little while afterwards, it was about a month after this when i saw my first NMI screen.

I reported it to Dell via the online chat system, who asked me to run the system diags, which i did (no errors found). At this point the headphone jack failed, so i had the motherboard replaced (found it better to call support, as they didn't seem to be able to understand it was broken when communicating online). So with my new motherboard in i ran for a day and the NMI appeared again.

At this point I formatted my drive and installed XP, on doing this i still got the NMI error, but less frequently. I contacted Dell once again, who decided to replace the Graphics card, the day after the card was replaced the error appeared again. Two days later another engineer arrived with a new motherboard and fresh RAM, after a discussion, we decided to replace only the RAM. I'd been running for a little over a week with no sign of an error, but you guessed it, it popped up again. I installed the fangui utility and set the fans to run high at a low temp, I still got the NMI with this, so that ruled out a heat issue, never mind the fact i'd managed to leave it on in my backpack for 30mins or so, it was positively cooking, but with no error.

This time I contacted Dell again, for the first time I was asked what order did i install the drivers, as usual I installed Chipset, Graphics, Network then the rest followed by windows updates. I was told by the tech, that the NSS (Notebook System Software) must be installed before anything else

With this I popped in My vista disk having downloaded fresh drivers from the dell site, making sure i installed the NSS first. One thing i noted, i'd had issues with the graphics drivers previously and it had taken some playing around to get it working, i had no such problems this time.

I'm by no means out of the woods as far as the NMI goes, but i thought it was time I posted having had this snippet of info from Dell regarding the NSS.

How many people are aware this needs installing first (or even needs installing at all)?

 

There's a lot of talk about this problem being a heat issue.

Since I replaced graphics and wireless drivers I have been able to run for days and have not seen another NMI error. It's been months since my last post.

- I did not have any hardware replaced.
- I did not do a fresh XP install.

There may be more than one cause to this problem.

 

Hi there guys , just to let you know about the experience i had with this problem..... heres the last email i sent to dell ...

Hi Michael ,

First can i say thank you for arranging the replacement of my motherboard and the graphics card so quickly, everything went fine for 2 days until...the Blue Screen of Death came up again ! I couldnt believe it lol, so i have done some extensive research on the internet about it, and it seems that im not the only one who is suffering from these problems.

The problem originates from a Blue screen with the following error :

Hardware Malfunction
Call your hardware vendor for support
NMI: Parity check / Memory parity error
*The system has halted*

After this i have to reset the machine by holding down the power button , when the machine is reset i get another Blue Screen but this time with another error, i actually get a stop code , it can be 1 of 2 stop codes

Stop 0x00000050 - Microsoft gives several reasons that can cause this.

1) Faulty Hardware- I have had 2 new graphics cards from yourselves and a new motherboard, i have also reseated the memory modules and swopped their postions around, unfortunately nothing seems to help.
2) Antivirus software - I have uninstalled the software i use and this has not worked either
3) Corrupted NTFS Volume - I have run CHSDSK /r to test and repair errors , but none where detected.
4) Incorrect Video Card Drivers - I have booted into Safe mode and uninstalled all the graphics drivers, then booted back into normal windows , im guessing im using a internal graphics card? Then installed several drivers:

http://www.nvidia.com/object/winxp_2k_mobile_84.63_2.html
The Drivers from the dell site , i cant link to it , but its called NR126106.EXE
http://www.laptopvideo2go.com/forum/index.php?showtopic=15175

None of them have worked so currently i have totally uninstalled all drivers.

The other Stop i get is Stop 0x0000007E - Microsoft ask you to :

1) Make sure u have enough disc space, i have over 10 gig free at the minute
2) Update ur Bios - This was done by the guy i spoke to for 3 hours the other night in India , using the remote connection
3) Update your video drivers - I did this already ^^ see above
4) Remove unsigned and 3rd party drivers, i have done this using a programme called Driver Cleaner Pro

After much goggling i found 3 very helpful thread on the internet

http://www.dellcommunity.com/suppor...message.id=4502&view=by_date_ascending&page=1

As you can see one of these threads has nearly 60 pages hehe , so its a well documented problem, i have done everything i can think of , installed new wireless drivers for my wireless card , reformatted my hard drive, swopped RAM around, uninstalled and reinstalled several different types of drivers, had 2 new graphics cards and a new motherboard. Im fresh out of ideas , i dont really want to have anything else replaced as looking at the threads in the forums nothing seems to have sorted out the problems for people. The only thing that does seem to work is getting a new machine. Obviously this is a last option for yourselves as i understand the cost involved , however i did pay a significant amount of money for a top notch gaming laptop and atm im only able to view webpages due to my lack of active graphics card. The last thing i want is for a guy to come and replace my hard drive or Ram only to get my hopes up for a few hours until the machine goes haywire again. And I dont really want to spend another 3 hours on the phone to a guy who is remotely trying to fix a problem that from my research doesnt seem to be able to be fixed in all circumstances . I understand that its not your fault at all and the service that you personally have provided has been fantastic , however im starting to pull my hair out now and would like a new machine so i can get back to normal

Thanks alot for reading and my apologises for the essay!

Dan


the guy from dell was VERY helpful and they have offered to replace my system, unfortunately they couldnt get it replaced for 30days so i have been offered a full refund. I understand that the prob should be cureable, but im very impressed with the service they have given me. I was running a M1710 512mb geforce 7900gtx by the way. I 100000% dont believe that the temp was to blame in my particular circumstance , the machine could lock up after a few seconds when it had been off all night.

Im gonna order a new M1730 tonight , and make sure i get 3 years warranty !

Good luck in fixing the prob you guys have , and thanks alot for the information that has been posted on here, it undoubtled helped me to get a fast refund.

 

Has anyone had any luck with getting this resolved out of warranty (or getting a cheap 7900 from Dell)? Mine just expired and this problem just popped up...E1705 with a 7900GS here...

 

just a followup to my last post where i thought i had the problem solved by pointing a small fan at the keyboard. it still works but if i play any newer more graphic intensive games such as any FPS released within the last few months the computer will still crash with the error. i guess the fan doesnt keep it cool enough with the newer games.

world of warcraft still works with the computer but prolly because its not as cpu/gpu intensive as the newer stuff.

bottom line im getting a new computer and never buying a dell. luckily this computer was a company machine.

 

I have recently received the NMI BSOD for the first time. Here are my specs:

Lenovo T60p (w/ FireGL 5200)
IBM wireless (Atheros)
2 x 1GB Kingston RAM
Windows XP SP2
Ubuntu Fiesty release

I've been using my T60p about 12 - 16 hours per day, 7 days a week, for about a year without a single BSOD. This is probably the most stable piece of hardware I've ever used. As an electrical engineer (microprocessor designer), I use my laptop with both Linux and Windows, booting on two separate HDDs. I stress my laptop's CPU, wireless, and graphics card. Given that I haven't had a single crash in over a year, I'm confident that my hardware is rock solid. Recently, I purchase a new hardrive, 7K200, and decided to do a clean install of Vista Business on it, just for kicks. I downloaded all the necessary drivers from Lenovo. Within the first two days, I received my first NMI parity BSOD. The data seems to point to the fact that this NMI issue is linked to a particular configuration of drivers, settings, and/or OS and NOT the hardware. This is substantiated by the past 50 pages of posts where people have swapped out every component and even received a new computer and have seen the same issue. For the few cases where the number of BSODs have decreased with a hardware swap, I suspect that it's the subtle change in the software or configuration that made the difference, not the hardware change.

The parity error has nothing to do with RAM, as the evidence shows. Most people are not using ECC RAM so there is no parity to speak of. The error message is most likely referring to signaling issues on the PCIe bus, where the wifi card sits.

It may be possible that this is related to heat in some cases as higher temps (GPU will contribute) will degrade PCI bus timing margins. However I've driven my laptop CPU and GPU to very high temps with high network activity without any issues. The one time I had an issue in Vista was when I was trying to watch a video on YouTube. Others have pointed out crashes when watching videos online as well as playing WoW. The common thread here is that online streaming videos and WoW (online game) stress not only the graphics card but the wireless card as well. It's most likely the activity of the wireless card (PCIe bus) coupled with a specific set of drivers and settings that causes this instability. Driver settings, configurations, and network activity play a large role in bus timing margins.

There does not seem to be any correlation to any specific brand. There does seem to be a correlation of failures with the Atheros chipset. I hope this is helpful.

 

Hardware Malfunction

NMI: Parity check / Memory parity error
*The system has halted*


Ok. So i have had this problem for about 5 months and basically quit gaming because of it lol. (only happens during games.)

So I decided i wanted to play some of my games again.

I went to the f12 boot options and ran the diagnostics. In the second battery of tests there is an option for testing Video Memory, and my card failed miserably.

So I called dell yesteray, and in about 1 hour of talk time was able to have them schedule a local tech to come and install a New 7900gs.

I will let you know what happens with the new card.

 

FYI - Dell replaced both my RAM and Video Card. The problem is gone. I didn't have to argue with anybody, btw. I did my due diligence by running the diagnostics ahead of time. After that, I used the Dell online chat (much better than calling, IMO) and told them I was having this issue. I informed them that I had run all of the recommended diagnostics and that I felt sure this was a heat-related issue since my I would start to see massive graphical artifacts in games before the crashes. The whole chat took about 10 minutes and 2 days later I had a tech come to my house to install the new parts. BTW, the tech said I had one of the cleanest systems (in regards to dust) he'd every seen (I regularly blew the fans out with compressed air), so it wasn't due to my system being clogged with dust.

 

Hi again,
I've been doing some testing over the past few weeks and have seen that it correlates to the PCI-E bus and the wireless card of my computer. I've been able to test on two different machines one that gets them and one that doesnt with just switching the hard drives and no software changes and identical machines. After no NMI errors for several weeks in the good machine we decide to switch just the wireless card from the good machine to the NMI machine and no NMI errors for a week during testing.
We switch the card back and within a day the error has occurred. Even after a complete reload with Windows Vista the error still occurred with the bad card in place. we are going to test in the next couple by switching the wireless card back and testing the bad card on the good machine.
the one frustrating thing is that there is no way to test the card really even with the factory diagnostic. Ive explained it to my technician and he believes me but has not been able to find something wrong with the test. Does anyone know of a wireless card test utility. maybe this helps someone or will help the rest of figure this out.

 

I hope im in the right spot to post. I am looking for a Service Manual for a Sony Vaio PCG-7Z2L (VGN-NR120E). Does anyone know where I can get one or any instructions about where all the screws are or disassembly instructions? Thanks Peter

 

New to the forums, I find alot of people with 7900gs's are getting this error, I myself included, might be something to look into.

 

Yes. This does seem to be a common issue. I have one as well but note that I have not had any major crashes since my replacement. At the moment I have reason to suspect however that they installed a different version of the mobile intel core 2 duo though. Noting that there are 2 different ones. One uses less power than other to startup. I traded off a random bsod for an intermittent power on issue that occurs only when I attempt to start from battery (I can always start from AC).

 

Did anyone have some success in replacing this out of warranty? I started getting this error some weeks ago and now my GS is DONE! and warranty is gone after 1.5 years...

 

Who is the manufacturer of your computer? If it is out of warranty they may still help you for a fee. If you cannot get any assistance from the manufacturer then you may be able to call their spare parts department if they have one. Dell does so you can do a search for Dell Spare Parts and come up with their number if you have a Dell laptop. Keep in mind that the video card in a laptop is not cheap.

 

I have a Dell laptop.. its an Inspiron 9400. And like all those people over here, I had the same nmi parity check problem and then my graphics card started making problems...

I'm living in Switzerland, we usually have better customer laws over here. I'll be calling them tomorrow so I can talk to a supervisor about this issue which is obviously a dell-construction related problem.

 

ive been doing a lot of reading about this issue.havent been able to use laptop for over a month and finally got somewere today. here is what i did on startup went into setup with F2 key. went to onboard devices and turned everything off, then shut comp down. then removed wireless card and turned back on. everything loaded and restarted with F2 setup again turned all on board devices back on and saved settings. finally restarted and no more problems so far been on for 12 hrs.
just thought it might help someone. it got mine working again

Hi,

I have a Thinkpad X60 and I get the blue screen with memory parity error, system has halted. It is not the memory, CPU or motherboard.

I had lenovo send me replacement memory and bought my own. It happens with all the memory. Ihave PC Doctor and have run tests both insafe mode and regular mode on the processor.

It only happens when I am online. I loose my wireless connection and when I go to repair it is when I get the error. Not always only intermitently.

I have come to the conclusion that the wireless adapter in my notebook is faulty. Many of you say you have this problem while online or trying to get online. The wireless adapter is most likely the cause.

Thanks

 

I'm having the same problem on my E1705 (running VISTA) described by ibinsanediego (May '07). Sometimes the cursor freezes or the screen freezes or the system just shuts down. Mostly the screen freezes and vertical rows of multi-colored rectangles made up of what look like bits of data appear superimposed over the desktop or over whatever work I'm doing? Please let me know if anyone else has experienced this problem. Anyone know how to fix this? Please advise...

 

Hello.

I had the same problem with my Lenovo R60, 2 GB RAM, ATI Mobility X1400. I couldn't run the performance index test under Windows Vista without getting the discussed NMI: Parity Error.

Today I installed the Service Pack 1 RC from Microsoft and the computer is running now for several hours without getting the BSOD!

Perhaps this helps other user too....

Greetings,

André

Check it out, Microsoft admits it's their problem.

 

It's not a microsoft problem. Microsoft is offering a solution to help resolve the issue.

 

Add me to the list of 9400/E1705 (GeForce Go 6900) owners with this problem. I am on my second go round with Dell getting a replaced video card this time. Already had the memory and motherboard replaced.

The motherboard replacement actually helped the problem go away for a good 5 months. Taking the video card replacement because this time around I am getting horrible pixelation after every crash.

If that doesn't help along with trying some of the things suggested in this forum, I will be seeking a replacement system.

 

Is there anyone getting this error that isn't running on a core 2 CPU?

 

It turns out it was the Wireless card in my system. after testing with different cards one would have no problem and the minute i put the original back in there it would do the parity bit error. but we finally ended up replacing the wireless card and so far I've been problem free for three weeks. Hope this helps.

 

just curious, since it seem to be a software/driver conflict for some, have anyone tried upgrading from xp to vista? i'm tempted to do it since i have a copy of vista, but i'm afraid that it takes up too much space (my hard drive is only 60 gb, and i need ubuntu on it for school/programming).

note i have never gotten an error or anything in ubuntu while playing warcraft 3 but occasionally my laptop goes through a phase where it crashes like a maniac and other times it doesnt crash for weeks.

i guess i'll give this a shot when i get back to school and get a decent internet connection. honestly i think i can completely switch to ubuntu, but sometimes theres new games that come out that i just have to play/try vista is a ****ty option for gaming, but at least it won't crash on me like crazy....

 

I have an Inspiron E1505 that pretty much has been having this NMI Parity Error since I got it 1-1/2 years ago. Although at first it might've happened 2-3 times a month, now it occurs almost once a day.

So I called Dell last week and a few days ago a Dell tech came out and replaced both the motherboard and RAM. He also cleaned the fan and fan vent.

The NMI Parity error occurred again today...

I'm going to call Dell and maybe have them replace the wireless card and/or graphics card next.

 

I would tell you in my situation that Microsoft is the problem. They downloaded a driver update for Atheros chipped wireless cards. Mine is a D-Link and on the D-Link website they did not certify any new update.

Microsoft Update decided since I had the Atheros chip in my D-Link Wireless N card that I needed this new driver. Since I have rolled back to the latest driver listed on D-Link's website I have not seen the blue screen come back again.

It is not always a new driver needed, but as in my case sometimes the "new" driver is the one causing the problem. Lenovo / IBM tech support could not identify the problem they actually had me send my computer back. I put my hard drives in another T-60 and the problem came up which led me to more aggressively look at drivers as the root cause.

 

I had my video card replaced and the tech also cleaned the fans. There was quite a bit of build up and dust in the system. I have installed fangui and am keeping a close eye on the heat factor. I expect the blue screens to start again at some point, the question is just how long before it does.

 

Hey dierk017 -- thanks so much for figuring out the problem with wireless card. I have an E1705 and have been having the memory parity error for over a year and this is the first solution I have seen for it. As it so happens, I just started noticing my wireless connection becoming less reliable.

So, I can't wait to replace my wireless card. The question is -- which wireless card did you use for a replacement? I'd hate to get another card that is also a problem.

Cheers!

 

I have a sony vaio with a core duo (not a core 2!!) having the NMI problem with an atheros wireless card. I have a feeling I'm in the same boat of needing a new wireless card. anybody else with a sony have this problem? I have integrated GMA950 graphics so there is no way it is heat related.

 

Which card? I have a Gigabyte brand version of the adapter that contains an AR5006X chipset. The 4.x drivers cause a Memory Parity Error but the 5.x drivers which are the newest ones provided by the manufacturer doesn't do that. If you want me to send you those drivers then let me know.

 

Thanks for the idea. I just found a driver on atheros.cz in the 5.x line that supports my card supposedly. I'll install that and hopefully know if the problem is fixed by end of tomorrow. The computer is getting the BSOD every 2 hours or so as-is.

I have a "Lan-Express as IEEE 802.11g" atheros card btw. Still cannot find the actual chipset number.

old driver is 4.2.2.21

 

Do you know what the driver filename is?

 

just installed it. working well so far.
old driver: ExpasAG.sys
new driver file: ar5211.sys

The real test will be tomorrow when I hook up to our school network that uses 802.1x authentication EAP/TTLS that's what makes the old driver crash.

 

Ah... ok. Yea. that would be one mine uses. Yours could be AR5006X or older as that is all the higher that driver goes.

 

well I've been pushing my wireless card at about 1mbit/s for 5 hours straight. no NMI issues at all. New drivers fixed all my problems.

thanks again!

 

Hi, I also had these problem a week ago, i tried to replace the memory but it didn't work. so i tried replacing the video card, now it's working fine.

 

Hey -

I have a Gigabyte GN-WI01GT (AR5005GS chipset).

I had the NMI thing about a year ago, which drove me nuts, but just took out the card, and used the stock Dell "WLAN 1390" card on my Inspiron E1505...

Last night I put it back in using the "comm_driver_superwireless_v.5.2.0.117.07.zip" - the latest from gigabyte, and am currently getting the NMI again.

What version of the driver are you guys using to not get the nmi?

 

Time for me to give my 2 cents. I had this error on an Alienware m5750 with an ATI x1800. It only showed itself when I tried to play World of Warcraft, about 10-15 minutes into the game. Naturally, I found this thread, and using what you guys have already been through I deduced that it was the video drivers. My problem then was similar to the OP's: drivers from ATI.com would not work on my comp, and the one (yes, they only had one) from Alienware.com didn't fix the problem. I even tried reinstalling the drivers from the CD that came with my comp, to no avail.

My fix:

Omegadrivers.net

Once I installed the driver from their site, the problems went away. They have ATI and Nvidia drivers, with their own interface for controlling your graphics card. Hope this helps.
