new one : 630/1100(2200)

evga 8800 320 stock OCed with rivatuner software.

I got mine stable at 640/1000, (though i suspect I could go a little higher on the memory clock) and scored about 12300 on 3dmark.

I actually had it up at 666/1075 and got a bench on 3dmark at 12800, but on stress testing it crashed spectacularly (I actually thought my PSU was dead when the power button on the front stopped working ... manually powercycling the PSU fixed it though, thank god) so I backed it down again.

I ran a GPU stress test and got it to peak at around 81 degrees, but that is up from I think 70 at stock. That is more or less acceptable, isn't it?

I have sucessfully run 700/1000 in the past but decided to try a test. I found a program called "Performance Test" that claims to test all aspects of video performance. I started at my stock settings of 515/798 and started to move the speeds upward. I noticed a "sweet spot" at 612/900 where increasing either speed, or both, would cause some of the benchmarks to go lower. The card was always operating properly, was cool, had no artifacts and everything seems stable at all speeds I tried. Since it is impossible to perceive any significant performance increase from the 612/900 I decided to leave it there permanently. Anybody else run into a performance drop off beyond a specific speed?

This one?

googling "Performance Test" is neigh useless

Yes, that is the one...

Here is mine

EVGA 8800GTS 640MB (Superclocked) 576/850
OC'd to 650/1000 temps idle at 61C max out at 77C

3DMark Score of 11663 and im still going ill update as i continue to push

Nice score + Nice OC

Hey gang!

I have the EVGA 8800 GTS - I have been tweaking with some OC'in and I notice my temperatures are way higher then a lot of yours...

For example: Idle.. I'm looking at Riva Tuner Hardware monitor and it says my card is at 68C
When I OC to 625 / 925 - I can go as high as 91C


Whats the deal here? Any suggestions? Is this accurate or are there other apps better for temp readings?

thanks alot

max temp for 88xx series is 100, i have seen many with 88xx card and their load temp is 90+

It's true that this card can achieve high temp. There are some "mod" you can do to reduce the temp.

1. Good airflow inside the case.
2. Adding Antec super cyclone blower just under the VGA card ( http://www.antec.com/us/productDet [...] dID=77194# ). It help a lot throwing hot air from your GPU.
3. Re-applying the GPU thermal grease with high quality one (AS5 or MX-2)
4. Use a third party watercooler such Zalman watercooler ( http://www.zalman.co.kr/eng/produc [...] 3&code=021 )

Evening ladies, beat this for a stock air cooled OC...

Leadtek 8800GTS 320mb

Stock speeds:
Core: 500mhz
Shader: 1042mhz
Memory: 713mhz

OCd:
Core: 670mhz
Shader: 1762mhz
Memory: 1024mhz (without pushing it, I may try some more)

So:

Core: An extra 35%
Shader: A massive 72%
Memory: An extra 44%

No Vmod!

I think I must have got lucky, I play Crysis for hours maxed out at about 42fps.

Did you use NiBitor to Vmod? If so how much can I go on stock cooling, and how much extra Mhz can I expect? Any advice would be appreciated.

WHY?

Hey Guys, I have an Albatron 8800GTS 640,

is 79 degrees in 3D games safe?

I have the GPU fan at 99% speed

OC'd
Core 513-621
Mem 800-950

P.S, I don't play 3D games too often so would it be ok?, (in terms of life span)

Thnx guys

So why have you overclocked it? Yes i *think* it reduces the lifespan from like 12 years to like 7 (well thats the case in CPUs anyway)

Anyway, 79 degrees sounds higher, but I think is ok for 8 series.

What does everyone else think?

8800GT SC (eVGA)

Core: 650 -> 700
Shader: 1625 -> 1752
Memory 950 -> 950

In most cases nearly doubled my frame rates.

PS:jonisginger, 78C for 8 series, for example is fine. With stock fan speed and clock, mine would top out at 91C. eVGA and their coolers on their 88 GT's can withstand 100C. So, by increasing the fan speed to 75% with this slight OC, the new high is 71C.

Ah ok, I may try a 0.01/0.04 vMod and see what my temps do.
