GeForce 6800 and random freezes

[betterdan]

I have the same problem with 5-10 second freezes during 3dmark 01 (other things also but as said above 3dmark 01 really brings it out). The video will be dim and everything just freezes. After 10 seconds or so it goes back to normal. This only happens when I overclock my vid card. If i leave it at stock settings it's fine. I tried turning fast writes off which helped to get it overclocked a little higher but then after a bit the screen just turns yellow and green even at 380/1060 on my GT which should go a lot higher. The temps are fine (the vid card idles at 51 and it gets up to the 70s during load) This is frustrating and I hope someone finds a solution. I am happy with my system but just hate seeing performance go to waste because I can't overclock my 6800.

Welcome to the club Dan. Its a bummer, isn't it. I am sure your GT would do 400MHz plus in an nforce2 board.

Soon after I got my GT, I fitted a VGA Silencer and flashed the bios at 1.4v. It became a tremendous overclocker and would do 453MHz in my old nforce2 board. OK a few artefacts at 453, but it was stable and never locked up or crashed. At 440, it was fault-free and rock solid. Now - in my force3 board - I can only do 410. And that's at 1.4v remember. At 1.3v I reckon it would be back down to stock.

Question: have you tried to see how far you can overclock with OpenGL games? I ran Doom3 the other day at 433MHz core for about 1 hour with no problems at all. Yet 3dmark01 would crash *instantly* at 433. It seems this "bug" doesn't affect OpenGL anything like so much, if at all.

I am seriously wondering if its nVidia chipset driver or graphics driver bug.

Frustrated though I may be, I can't see the point of switching - for me at least.

The fact is, I *can* run 100% stable and problem free at 410/1120. OK, so its not as high as before, but heck - how much faster would an X800 XT-PE really be? And would I actually be able to notice? Probably not.

The only other issue is the borked video processor. But with regard to that, (a) nVidia say new drivers will fix it, (b) I don't watch any HD videos anyway & (c) ATI cards are borked too!

Just my 2 cents.

ATI plays games faster if you ever check the charts. And since people are having problems with the Geforce 6800, they aren't even getting the speed they are suppose to be getting with it. So basically your wasting money on this monstrosity which doesn't even give you the speed its suppose to. Although X800 is surely faster in games than the geforce.

So basically, you will notice a big difference between the Geforce 6 and the X800.

By the way, the x800 problems aren't as big as the geforce 6.

I can't be bothered to go into a big argument, so I will just say this and then thats it:

1. GF6800 is faster in several games, and especially in anything OpenGL.

2. "Not getting the speed they are supposed to be getting"???? My only "problem" is I can't run more than 60MHz over stock. Stock is 350, I can run 410 fine. I used to be able to run 440. So your comment is complete bollocks.

I wil not respond to any other messages from you because I think you are a troll.

Okay well long story. I bought a BFG 6800 GT 256MB agp card. I wanted to set up dual monitors on it but it only had a svid out, so i got a converter and was using that. I let the system run overnight with it in, and when i got up the screen was full with just a bunch of like blocks of black and white and different colors, It kind of looked like a NES game cartridge when it wasnt in all the way, I beleive its called artifacting or something like that. So anyways, I called BFG tech support and they told me to send the card in, but said it would take a while to get back to me, which i didnt want. So i talked to my manager at bestbuy and they let me swap out cards for a brand new 6800gt. I brought that home last night, and didnt do anything with the converter, just hooked it up normally through the monitor. After about 2 hours the card did the same thing, started to artifact. I called BFG again, and we narrowed it down to more than likly its not the card, something in my system. We swapped out each stick of ram and check that, its all good. The kicker is that the only other card i have is a geforce 2 >.<, and when i use that the system is fine. I beg if anyone knows what the possible problem could be help me out! here is my system specs.

2.4 p4
asus p4s800 mobo
1gb of rosewill PC3200
2 hds
1 pci soundblaster
422w PSU
1 cd-rw

again any help would be greatly appriciated, Sux trying to play games on a deforce 2 32mb =\

Just tried Doom3 at 390/1080 Chippy and no problems at all (raised my Doom3 timedemo score to 69.8 from 64.9) I then tried 3d mark at the same 390/1080 speed and instant freezeup and dim video for 10 seconds at the load screens. I still let it run and it played the actual timedemos fine just freezes at the load screens. I also noticed some throttling i guess you would say because with no overclock on the card the first dragothic timedemo starts out with me getting 500fps and with that overclock it was getting 450-470 wtf? Oh I also forgot to mention that I set the 2d and 3d speeds the same.
It seems you are right about it affecting only direct 3d games and i've seen others mention that before too. Now we just need Nvidia to fix it.

What happens is that after a "freeze" the GPU speed has dropped right down. Thats why it benches slow. Then the next benchmark loads up, the GPU speed clocks up high again > it freezes > then clocks down again and completes the next test, also at low GPU speed. And so on, and so on.

Each time it freezes, the GPU speed drops.

Hey my card shipped running 425/1100 what do you make of it? Not complaining!

ATI sucks ass. The geforce 6800 series is a much better architecture than the x800. There may be a few bugs with the nf3 and directx, but my GT Screams. The only thing I like about ATI is that new cooler they got on the x850. If I could get a card with a stock nvsilencer that would rule.

I know, I love Nvidia and Geforce. Remember, I own and am using a geforce 6800. But out of tests on site benchmarks. 70 fps, but most people are getting 50 fps when there computer has 10 second freezes. The reason why I said the the fps is lower than it supposed to be is because the Geforce 6800 has imcompatibilty problems with other hardware. Well duh, that was the problem in the first place. So I conclude that we all take our time to fix the geforce 6800 while all we are doing is limiting the graphic card's hardware, though what we really shouldve gotten from nvidia was a graphics card that was more playable than having 10 second freezes or permanent loop freezing in some cases.

I'm experimenting the problem that you are talking about on the 3dmarks bench, my card is an xfx 6800gt flashed with the 1,4 bios (I edited the bios with same voltage and same cloks -400/1100- on both 2D and 3D application) but I note a strange thing: afther a fresh installation of win xp, nforce drivers, and nvidia video drivers everuthing was fine, no random freezes in 3dmark and nice score (23000 in 01 and 12000 in 03).
But afther that I reboot the PC the story was the same.
I hope that nvidia will do something for this or I'll buy a k800t mobo

I took out my DFI LanParty UT3 card and put in an MSI K8N Neo2 Plat. Same problem with the 6800 Ultra: benches everything fine at default 425/1100, but instant lockup in games when I overclock.

Man, two different architectures (S754 vs S939), two different manufacturers, two different CPUs (Claw vs Winnie), and the same problem with the NF3 chipset!

Maybe Nvidia doesn't want you to overclock their cards. There is an ID the chipset picks up from an Nvidia card so it knows when a card is overclocked. Is anybody having this problem at default clock?

[rflair]

HAHA Clevor I did the same thing put my 6800GT in a DFI Lanparty and the studdering was worse then with my ASUS K8N which just paused and then resumed normally but same chipset. I swapped to the DFI board anyway, it's a great board, have my old BH5 ram running 250mhz fsb.

I'm not gonna let this bother me no more, with fastwrites off every thing is great and my GT runs 400/1100 no sweat.

Mine f**ckin stutters @ 370/1000! Not as bad as you guys ( 5-10 seconds ), its more like a jitter. Just a quick 1 second pause, then it resumes. Right now its @ 400/1100, but the stuttering is really buggin' me. And btw, the x800xt/pe are infact better than the 6800 series hands down. Beats it in Far Cry and Half Life 2, and edges it in doom 3 with the new drivers. Damn it, why did I switch from ATi *slaps himself*

Yeah, but I cant. Even at 370/1000, I still get these little pauses. Plus, ATi has much better IQ with AA/AF.

You mean that on DFI UT you need just to desable fastwrite to stop the freeze on the 6800 gt?
And need to desable just in the bios ar also with rivatuner? (I read something about that) How do you have to disable with riva-tuner? (this software is not really user-friendly for me) may you explain were are the option in rivatuner to disable fastwrite?
Thanks

All I did was equal my 3d and 2d settings in coolbits2 and I have had no issues since.

I have a BFG 6800 OC untill this morning I could not get it to run. What would happen I would install the NF3 chipset drivers, reboot, then install the Nvidia video drivers. I would reboot and after the Windows splash screen it would lock up with a few white pixels in the upper right hand corner of my screen.

I tried all different versions of the chipset drivers and video drivers, using driver cleaner inbetween each install. This went on for almost 2 weeks. I finally gave up and removed the heatsink from my card, I have the dual fan version. I cleaned everything off, scraped off the thermal "blankets" and put a nice thick coat of AS5.

And now the card WORKS!!! (snowlol)

One thing I did notice with Coolbits and equal clocks is that if you use just the mouse to set the clocks it usually doesn't get 100% equal clocks between 2D and 3D. If set 1100 ram in 2D and 3D one will be 1104.2 and the other 1104.8, a difference of .6, but during a run of 3DM01 the card throttled to the slightly lower ram speed. If however I use the arrow keys to move the sliders I can set 100% exact same clocks, it seems there are 10 arrow presses either way for each Mhz and to get exact 2D and 3D clocks you have to use the arrow keys.

Also if you flash a bios with equal clocks the clocks are not 100% equal, the same marginal difference happens, maybe the BIOS editors don't set the extra decimal place bit.

I'm going to check with a HEX editor and see if there is another setting for the decimal place.

Very odd. For me, 1 arrow click = 1 MHz.

At the end I placed an order for an abit k800t. I hope that with this mobo the 6800gt wull rock. I will sell my dfi 250 ut wen the new mobo will arrive.

Sorry Chippy its only for the RAM.

I see. But now I am really confused. The ram is always the same for 2d and 3d, right? You can't set different speeds for the ram, correct?
