What kind of BIOS and motherboard do you have and where is this option?

Default Re: GeForce 6800 and random freezes

Here's my story..I got the Geforce6800GT back in 04 and immediately had the stuttering problem. Fixed that by turning off fastwrites like everyone else did. All was good until this past summer when I started playing Battlefield 2 and World of Warcraft. Back then I was using some 66.x drivers.

In BF2, the game would stutter (with the sound looping, as if fastwrites were still on) and essentially freeze, but if I pressed ctrl-alt-del to get to the Windows Security screen, then cancel out of it, I would be right back in the game without a problem.

In WoW, the game would stutter with the sound repeatedly looping for about 5-10 seconds, again similar to when I used to have fastwrites turned on.

I eventually upgraded to the 85.77 drivers which fixed both problems..until recently. BF2 still seems ok, but in WoW the problem now is I get artifacting (polygons where there shouldn't be any, missing textures), and an occasional 5-10 second freeze again. But this freeze is different, the sound doesn't keep skipping in a loop like before, but keeps going like nothing's happening, and it's solely the video that comes to a halt. And, every so often I see a white flash or flicker on the screen. This only seems to be in WoW though.

This is all under Win2k SP4, with a nforce3-ultra board. I'm going to try upgrading to the newest nforce and forceware drivers, but has anyone else experienced this, particularly the problem with warcraft?

It looks like you have overheating or "plain old" freezes like I had.
These are quite Opposite ! . you should check Temps , and get a big hone fan to blow into the PC to make certain its not a bad cooling issue. I would check that the thermal goo is ok.

I have PNY BIOS , but any GT's BIOS would enable you to raise the voltages. You should try that before everything else as its quite easy to do with niBitor look at www.mvktech.net for appropriate BIOSs and guides on how to.

I still have NF2U board.

GL.

btw, if u got problematic card and try to dump it, than the reduced price is your penalty. Try and fix it. No reason it shouldn't work.
That is not a solution... I don't think it is healthy, giving 1.4v to a GT. You will destroy it sooner or later. How long have you benn doing this?

I want to know the effect of modding the GT BIOS to Ultra, so the voltage will increase, the card will think it is an ultra, but will it push ultra speeds on the core/mem ? My GT can not handle ultra mem speeds at all, max OC for the memory fo me is 1050 mhz ..., what to do then?

By increasing the voltage your clocks will be higher. That is for sure. But your card will still be a GT, it will have the same clocks (350/1000). You can edit the clocks too, however. To 400/1100, for example. 1.4v and 400/1100. Like an Ultra, isn't it? But it will still be a GT.
If you want your card recognised as Ultra, you need to flash a real Ultra bios. As far as I know the memory timings on the Ultra a different (worse), so your GT flashed to Ultra will be a bit slower than a GT at Ultra clocks. If you get what I mean.

My card idles around 61-62 C and when I play Warcraft it's around 70-75. Is this normal?

Crap... Just installed GTA: Vice City for old time's sake and have stuttering. I can throw that 8x.xx idea out the window. CoD2 still continues to perform fine, though, which is pretty odd.

...and if someone still wants to take a stab at my API querying question that'd be super.

Hmmm, undercloking my vid card seems to make the GTA:VC stuttering go away, at least to a great degree (only tested it for about 10 minutes at a time). And I just started playing FEAR. Aside from this game eating up a massive ammount of system resources, there is no stuttering, even while the card runs at normal clocking.

Hard to say, if I was answering your question, then no that is not normal. Does your case have good airflow? In a warm room? My idle temps are 49' / 32', but I have 6 case fans and a copper heatsink on my 6800 GT. Oh yeah, what kind of card are you referring too? Is dust a problem inside your case?

During my 5-10 second freezes Rivatuner reports a core freq. of 11.3mhz. Anyone out there have an answer for this? Why would the card throttle to 11mhz I'm perplexed . Someone please help
