View Full Version : GeForce 6800 and random freezes
Ya occationally I get a little bit of a sound glitch or something in Far Cry even with stock speeds
Are you using patch 1.2? If so uninstall it and re-apply patch 1.1.
I set my 2d and 3d clocks the same freq, and so far I have no lockups in far cry and the rthdribl demo. This is too weird. I will do further testing and report back. :clap:
After a full day of testing, I have not experienced any lockups with the 2D and 3D clocks set the same. (450/1.2) I'm going to call tech support today so I get the card exchanged. I don't think I should have to change the 2D clock to get the card to run stable. This problem seems like a BIOS issue, any comments on what may be the cause of this would be appreciated. Thanks. :)

Most people have to set the 2d/3d clocks the same. It doesn't matter for me, I still get a 10 second pause, but it goes away after that. So, that doesn't bother me. Just wait and see if nVIDIA fixes this in the next driver release.

So you don't think this is a BIOS issue?
From my experience dropping back an overclock a bit really helps stability and you won't really notice the loss of a few FPS.
Some games tax the video card differently than others and it is not always the games you expect that cause the lockups/freezes.

If I underclock the eVGA U EE, I get the same type of error. (games crash ETC) but if I set the 2D clock to the default settings of the 3D clock (450/1.2) the card works like it's supposed to. I'm not sure but this seems like a BIOS issue to me. Any comments?

Well I'm not sure if I'm having the same problem here, but I'm getting mini-freezes of about 5 seconds every so often.
So far, it's been most prevalent in CoD but I saw it in FarCry too.
Game just total freezes for about 5 seconds, then picks right back up. All at random times, not after a new level loads or anything like that.
BFG GT OC @ 411/1110 2D & 3D, 61.76's
FW's on.

Yep thats a classic example of the problem, turn FW off and the problem should be solved.
Just had an update from XFX support and they have informed me that FW should be disabled by default in the bios. Looks like it is known and should be disabled in the first place then.
i have a PNY 6800 Ultra clocked @ 440 / 1200 whitout any problem.
Now if i clock the card at standard core e memory speed (400 - 1100) it just look up / freeze :screwy:
I have contacted PNY and this is the answer :
"Dear costumers, the problem is the bios, the card is clocked at 400 mhz for core in 2D mode and at 425 in 3D, it's internal bios setting and the famous coolbit2 can't underclock your 3D mode, it still remaining a 425 also it's downclocked at 400 and the results are : 400 mhz 2D and 425 3D.
this settings are wrong and causes freezes and lockups.
I suggest you overclock your card at almost 430 mhz core speed in both 2D mode and 3D mode, in this case your result are : 430 / 430 in both mode and this settings are fine for all your games and application."
Best regards
Pny tecnical stuff Europe.
P.S. I hace traducted the answer from italian to english, so sorry for bad language.
hope this help someone.

I have a KT800 Chipset, and i have the 5-10 second freezing problem as well. I have tried to disable fastwrites, and set identical clock speeds also -- neither worked. As soon as I go anything over 425 on my core, I get 5-10 second freezes -- usually at the beginning of the Level (painkiller/far cry) Never any artifacts though.
Frustrating.

Where did you disable fastwrites? Despite disabling in the bios for me it was still enabled. Its best to check it is actually disabled using RivaTuner.

i m also having random freezes......i disabled fast write option from nvidia driver properties........cal of duty worked fine for me but 3dmark03, 3dmakr01 and far cry are still causing the random freezes.......wat should i do plz help...i am using latest nvidia official drivers.

Have you also made sure your 2D and 3D clocks are set the same?

well no they both are differnt....
my 2d clocks are 400/1100 and 3d are 425/100........how can i set them same......wil it solve the problem.

Either RivaTuner or the Coolbits 2 tweak will allow you to do that, and I personally prefer the latter. The following thread will show you how to do it using Coolbits 2:

I've turned fastwrites off in BIOS, and in RivaTuner. I've verified that they are off with wcpuid.
Still pauses at 430 core.

Set both 2D and 3D speeds the same, best way is to use coolbits, (avoid coolbits2 its pants).

I did have a problem with random freezing mainly noticed in FarCry (very card stressful) and when attempting to bench in '03
Yes I know there have been several threads but no one has posted a concrete solution. This worked for me and ALOT of other people in the OCUK forum.
First of all I thought heat, then I thought power related. However after lots of testing and forum posts it turns out it was Fast Writes being enabled causing it. I cant take credit but it definitly fixed the problem.
Interestingly disabling it in bios did not disable it in windows and I had to disable it using RivaTuner.
Also instersetingly for people not experiancing this, disabling Fast Writes appears to allow higher overclocks for people using all types of 6800s.
This appears to be a problem specifically on the nforce3 150/250/Pro/non-pro chipset ironically (as far as we know).
The problem has been posted by people in various places but its never been categorically fixed to my knowledge anyway (I did lots of googling believe me!). So I felt it best to post as a FYI for people.
Haha..thanks. I'll try that later...430 core doesn't pause for me in 3dmark03 and I didn't know this..however any higher and it does, producing terrible scores.

Set the 2D and 3D at the same clock speeds. Still no luck at 430.
Tried the newest drivers as well.
Odd.
sure your not just paging to the HD cause of lack of mem? or excessive stuff running in the background? Try disabling all overclocking on your computer

I have the same random freeze/low fps problem. I have allways run my pc's with FW on without a single problem on Ti's and an FX.
The freeze first showed up for me a the other week on my FX 5900XT when i changed to driver 61.76 whql. Since then i have installed a 6800GT and have moved to 61.77 and dx9c hoping that this would solve the problem, but it hasn't.
I am guessing that this is a driver issue and not a bios/FW/game related problem because the problem was on my FX card also so its not only 6800's. Anyone using drivers earlier than 61.76 have this random freeze/low fps problem ?
Im gonna roll back to a pre 61.76 driver, or maybe give 62.xx a try.

Go figure.
I fixed this problem on my XFX 6800u By flashing the BIOS per these instructions:
http://forums.overclockers.co.uk/showthread.php?s=&threadid=17261579&highlight=6800u+BIOS
Fixed the problem + I'm stable at 450/1200.
I think it was the .1 on the core voltage that made all the difference.

Hi
Some questions for you ;)
-Cooling? Water or stock air cooling? Temps?
-450/1200 in 3D only or in 2D/3D?
-No Problems in any Bench, Game etc...
-Revision number bios?
Well, thanks in advance! :nanahump:
@ NOXIS:
Hey "Nox" ;)
Could you do me a favor?
Can you examine the "new" Gainward Bios they provided for the GW Users @ their forum some days ago?
Perhaps there is a different voltage setting in the bios, `cause it`s not a good overclocker. The XFX works good for a lot of People?!?
Hint: Perhaps the GW Bios is good to be tweaked, cause the Fan behaviour is little different from reference: It spins faster than reference when a 3D application is started. --> Louder but Cooler ;)
Perhaps you can check this out , too?
Thanks in advance Noxis :)
Bye
