8800 GT and crysis problems

[mugana]

I just switched out my 8800 GTS 640mb and tried the 8800GT. It is the EVGA superclock edition which is 650/1900.

The 8800 GT ran 3dmark06, quakewars, battlefield 2142, CS:S, Lost planet demo, ATI tool artifact testing with zero problems.

However, when i tried crysis demo, i got artifacts in the form of red pixelated squares followed by a hard freeze or BSOD.

I was using 169.04 beta and winxp. Is this a bad video card or just a problem in crysis? I am leaning towards a temp problem because i noticed that many people do not have issues in crysis.

The card at stock has a low fan speed. Some people's cases have better ventilation than others (my idle is 57C but after 30mins of Crysis on high/medium my core temps only get up to 65C -- although this was nighttime when my room was like 12-13C temp). Some people have reported something like 15C increase in temps. If you don't mind you could always increase the fan speed a little bit via Rivatuner. Although if you have a quiet case like me I can hear as little as a 5% increase in fan speed, so I stock to stock (29%).

I even set fan at 60% using rivatuner and i managed to play crysis alot longer but it still ended up giving me red squares and a freeze.

Also, in ATI tool, max temp seemed to be 80c. It was 92c when fan was at default

This is what i see. This is someone else's screen but it is exactly what happens to me

Yeah, that screen is mine.... i am suffering freezes 99% times I play Crysis. And also with 3dmark06 set at 1900x1200 AA4x and AF16x... heating the core

I just use RivaTuner and see how my system freezed again during Crysis bench, but the temperatura was only over 78º, thats not too much, isn´t it?¿

After that i ran again the benchmark and i could go through it setting my GPU FAN at 100% speed... (65º max hit)

So?

 

[math20]

From what I hear there is a pretty crappy fan on the card, you'll have to bump it up to 80%+ or maybe get an aftermarket cooler. I'll be putting liquid nitrogen on mine when I get it

 

[sandman9]

So.... keep the GPU fan at 100 % always, at least while gaming. Its what I do with my 8800GTX.
As soon as I finish gaming, I switch back the Fan to Automatic Control using nTune.
Also, I always try to avoid Factory Oced Cards.... had a bad experience with a factory OCed XFX 7900 GTX.

They really should have left the dual slot cooler on them.

I set my fan speed to 70% (bit annoying, but I'll eventually get my FC-ZV9 on the card), and I just played some of the demo (had to start over, the game looks SO damn good now) and my highest temperature was 73C, with the card running 710/1782/1900.

In ATi Tool, what is your second temperature reading? Mine reads 37C idle (47C GPU idle), and it's some sort of ambient temperature, which hints at the airflow you are getting around the card.

I also use a PCI exhaust fan which is placed 2 slots under the 8800GT. Not sure how effective it is since warm air rises, but ever since I put the FC-ZV9 on my 7900GT a long time ago, I've had it to help exhaust warm air. It also help to get airflow under the card since an exhaust causes negative pressure which should cause some extra air to either come in through the send vent, or from the front intake.

And overall, Crysis runs well on XP for me.

 

[mugana]

i have my 8800 GTS back in but i get a reading of 0c for my ambients. Im sure that is a wrong reading

 

[HitMaker]

Ok, i am so confused...

Now i passed 3 consecutive benchmarks of the World in conflict demo. 1920x1200 Very High Settings (AA4x and AF4x)... and it didn´t freeze... wth?

Look at the temperature:

Now what?

 

[alcoholbob]

I don't think 80C is even that bad, Nvidia cards are rated to run fine at higher temps than that.

As for your Crysis artifacts I wouldn't put *too* much stock into them because it *is* the demo and not the final game. And it sounds like it might just be Crysis has problems with your system. A lot of games are ridiculously buggy these days (Bioshock). Hell I can't even select advanced options in Crysis because my mouse cursor and the area that it highlights are actually several cm apart. I can't select advanced options since in order to highlight it I have to move the mouse off the screen. I can only run this game at medium, and it looks unimpressive to say the least.

 

[HitMaker]

yeah... playing CoD4 demo... i played about 5minutes until the core temperature went over 78º.. tu 79º and ... it froze again... damm!

My god.. what a weekend!

 

[pcslookout]

Try putting a system fan facing the video card cooling it off or open your side of your case then put a fan on the side.

See if that helps any.

 

[HitMaker]

OK no sense here. Playing Cod4 with GPU fan at 60% and of course... it froze again! damm... the temperature was only 66º!

Did you try opening the side of your pc to see if it helps any?

 

[HitMaker]

Why? is 66º a dangerous temperature? i don´t thinks so, there is something else. Now i am benchmarking the card with Worid in conflict demo... its the 5 loop i do with its benchmark, and the temperature is over 83º and its still working without getting frozen!

.... i don´t know what to think..

Probably a lure, making SLI look like even that more viable an option. All those nForce owners out there, I smell nVidia's marketing gears burning...

 

[Cheex]

Have you tried to reinstall the Crysis Demo?

Maybe a bad installation or just an issue regarding Crysis only. Your other games seem okay in my opinion.

 

[HitMaker]

Yes i tried

Now lets see the most weird thing:

Tha card went over 85º after several loops of World in Conflict's benchmark.... it didn´t freeze

And also it wen over 89º after another several loops of STALKER's personal benchmark.. and it works without getting frozen...

A single slot card and for the Geforce 8800 GT MSRP at only $199.99 really helps make it a great SLI solution but SLI can be a pain in the butt at times as well.

That seriously looks like bad video ram. Are you overclocking and if so try stock and if still doing it I would RMA the card.

 

[Tangman85]

I would advise you just get yourself a second cooler, I have a simple fan blowing straight at my graphics card and ALL my problems went away and the card never reaches 55C - just get a fan, any fan as long as its "silent" enough for you and you'll be fine.
Artifacts are caused by bad ram or overheated ram as you mentioned, the GPU can run 120Celsius:ish on the 8800Series, at least the g80 chipsets, I heard that 8800GT runs hotter, up towards 90 Celsius compared to the 80 on 8800GTS, so as I said, get better cooling, preferably an outer fan and you're ace.

EDIT:
bad RAM is usually 5% of the problems, overheated RAM is 95% of the problems - when it heats up it gets exhausted and exhausted RAM is seen by the system as dead RAM, also your shader clock is seen as non-responsive and a reboot usually solves the problem but this doesn't happen if you keep the ram cool.
Another occurrence can be your monitor screwing it up...take a screen shot in game and open it in paint or whatever and see if the picture is fine there

 

[mugana]

I am not overclocking at all. My card does come factory overcloced at 650/1900, but it should be able to run at that setting.

Also, it is impossible to take a screen because the whole system freezes up.

 

[bryanW1995]

nvidia was very concerned about partner cooling solutions before 8800gt shipped. I would rma the card and hope for a better one this next time around. Why couldn't they just use the 8800gts fan???

Yeah, that's the one thing i love about my 8800GTS is the fan. I don't care that it takes up 2 slots. It keeps the card very cool and quiet. They definitely should have used the GTS fan for the factory overclocked cards at the very least.
