Lads and Ladies.

I have a problem with my BFG 6800 Ultra of which i thought I had fixed. It still reboots, although not as much as it used to do since I flashed the bios to the latest that I could find, version 4.

I load up counter-Strike and every now and again it just reboots my PC, without warning.

My questions are as follows:

Is it possible to download a bios that disables fastwrites on the card, as riva tuner refuses to turn them off, i click off, and apply and they come right back on again, the same for SBA.

Is disabling the fast writes in the riva tuner disabling fast writes on the card, or my mobo BIOS, because I don't have a fast writes option in my BIOS, and backed up when I do a system info test in 3D mark, it says not supported under my mobo section.

All's I want to do is make sure that fast writes and sba are definately off so that I can verify that this is the problem or not.

Also, is it plausable to flash my card with another cards BIOS, and if so, which is the best BIOS to choose?

This BFG 6800u is overclocked as standard, whether this makes a difference or not.

I have increased the DDR and AGP voltage a little, but kept these voltages within the safe band, i think i tweaked it .1 of a volt up for both.

I know there are a lot of questions here, but this problem is really driving me nuts, I only play Counter-Strike, no other games.

Any help would be REALLY appreciated, thanks :)

What PSU do you have? Is it providing enough juice on the +12 rail?(18amps or better). You have both molex plugged in correct? I have a BFG 6800U and have had zero problems.

why do people always point to the PSU first?

Although random rebooting can be caused by insufficient power. It is not wise to jump into conclusions.

The thing is that there are thing you can do to help eliminate other issues that could be causing it.

the first thing you should be asking yourself is. Has this card been working normaly before, if so for how long. If it was oprating normaly for two weeks (depends on usage) or longer then you can eliminate Card, Mobo, and PSU. See how one simple question can eliminate things that could cost you hundred of dollars to replace just to find out that you still have the same problem.

Viruses can cause these intermitent reboots, Spyware can bog down computers to a crawl and steal valuble info. Remember that.

Since the dude has allready flashed the bios to the card, I doubt he will ever get the thing back to normal again.

He should ask himself this question: Was it ever working normaly before flash?
I would assume he had. This means that the bios did not have anything to do with it. This is why it still reboots.

I helped my brother fix random rebooting with his 9600 256mb. All he needed was to flash the bios of his MOBO, which updated a known issue with 9600 and 9700 cards, as well as the latest official driver for both the mobo chipset and the video card.

I have a new antec 480watt, bought specifically for the new gfx card. It has 2 specific agp power leads on it, and i'm pretty sure that the 480watt is enough to power it.

It has never worked correctly since the day that I bought it, i've used numerous drivers and reinstalled XP about 10 times in the last 4 weeks, each install I tried something different. Service Pack 1, Service Pack 2, new drivers, old drivers, the original drivers on my cd etc etc.

This problem only affects me in game, (Counter-Strike), and since I have flashed my bios my PC reboots far less frequent, although it still does it from time to time.

I am coming to the conclusion that perhaps editing the revision 4 bios with disabled fast-writes so that I don't have to do it with Riva Tuner (I sussed that by the way, it was under the bootstrap settings or something similar, and I had to reboot my PC) is the way forwad - is this feasable?

I've had fastwrites disabled since I sussed it last night, and played about 5 games so far, it hasn't rebooted as of yet, although it went all day yesterday and only at tea time did it decide to reboot, twice in sucession.

So what i'm wondering is, can I disable fast writes in a BIOS editer and save the BIOS and flash my card with that?


By the way I have the latest BIOS for my mobo, I flashed that a while ago and afaik there are know updates.
Thanks for the replies so far fellas, it's appreciated :)

I had a very similar problem with my GT.

HL2 would reboot uring play and any Unreal engined games would reboot on exit. I disabled DEP which comes with the Athlon 64's and all has been well since. Havnt had 1 reboot.

Obviously thats only applicable if your running an A64 system.

You should be able to change it in the bios options, no need to edit the bios.

Also check the timings on your RAM you can relax the timings for better stability.

BTW what motherboard do you have?

I had very similar problems with my BFG6800 Ultra OC. 2D worked flawlessly but 3D would either freeze or give reboots almost every time I tried to play a game.
I tried replacing my powersupply first off, I purchased a Ultra X-Connect 500W. That did noy help one bit. I tried turning off fast writes, thats was no help.
Finally after much reding and research I decided to flash with modded BIOS. I downloaded the BFG 6800 Ultra OC rev 4 (http://www.mvktech.net/component/option,com_frontpage/Itemid,1/) BIOS. Then I used NiBitor 1.9b to change the 3D voltage to 1.5, up from 1.4. I did not change anything else, only 3D voltage. Then I flashed the new bios. Now the card works flawlessly. The card does not run any hotter during gameplay. Max of 82c during 3d mark 05, tracked with Rivatuner.


I know its not what you were asking for but that is how I stopped my 6800 from freezing and rebooting.

Also I did this only 2 days ago, and no problems yet.
