8800 Overclocks: Post yours

[javimars]

676/1051.. just ran 3dmark06 and got 11554
i think its running stable...i dunno!!! i want the 8900 to comeout already .. 1 teraflop!!!!!!!!!

I have a factory overclocked 8800....I have been able to reach 631 core, and 1060 memory.

 

[Mugz]

XFX GeForce 8800GTS 320MB (factory OCed version)

Stock speeds
Core: 580MHz
Mem: 900MHz

OCed
Core: 675MHz (can go higher, but then the PC randomly resets itself)
Mem: 1050MHz (haven't tried pushing it higher yet)

My targets are 700 core and 1200 mem, if not more.

 

[Spikke]

EVGA 8800GTX
I just oc'ed it to the superclocked specs.

Core: 620
Memory: 1000

 

[Mugz]

How the hell do I bump up the voltages for an 8800 in Nibitor? I haven't OCed a Geforce since the 5700 came out...

inno3d 8800gts 320mb

core: 675
memory: 1000

I pushed my 8800GTS 640 Mb (stock 513/792) to 700/1050, without crashing or artifacts in 3DMark, and the max core clock is 713 Mhz, than ATItool shut off XD But, now I'm running @ 600/800 ... Fast enough for me 😛

 

[Mugz]

770/1200, hardware vmods, Zalman 8800GTS watercooler.

Anything further and it dies.

 

[nick_000000]

That is a serious overclock Mugs, what app are you using? Nvidia are holding back the voltage on us me thinks.

 

[Mugz]

Coolbits to test the settings, Nibitor to keep them in the VGA BIOS (I've now flashed that card about four times, would've been two but I had a cockup).

Yes, they are holding back on the volts. In Nibitor it offers me the option of ?.?V, 1.3V (selected), 1.2V and 1.1V. I'm not risking that ?.?V, I feel safer with a 10KΩ variable resistor on the relevant points.

I'll post more details later - boss just walked in 😉...

I have a superclcoked 8800gts and i installed rivatuner because i wanted to overclock it a little bit. Rivatuner is showing that it is running at 58C! Is that normal? My Q6600 w/120 extreme never goes above 49C @3.0ghz(Orthos x2). Wont the temperatures rise even more when im in game? 3dmark06 completes fine though. 11k with the graphics at stock. Vista 64bit

 

[vonwombat]

It's normal, set the fan speed to 100% if you want it to stay at lower temps. Mine is idling at 52-60 with 100% fan speed and 55-65 with default fan speed.
I overclocked mine to 650/1000, no artifacts, got 11015 points in 3d mark paired with a E6420@3Ghz.

 

[nick_000000]

Just Flashed my 8800GTX to 626/1000 not quite 770/1200 but at least its a boost from 575, aint up to doing hardware mods yet 🙁. May go up higher 650/1100 but see how the temps work out first.

 

[Mugz]

The moment you touch voltage, upgrade cooling. [/rule of thumb]

 

[nick_000000]

Don’t worry there is plenty of cooling, I like to have the fans turned right down though for quietness I have a Watercooled setup on my E6700 and 8800GTX 😗 but I felt the tubes last night and they felt quite warm. I don't want too go to 650/1100 and find I have to turn the fans all the way up. Spose I am being a bit fussy if there .

 

[Mugz]

Larger radiator, maybe?

 

[nick_000000]

I have a 2x120mm rad (top) and a 1x120mm rad (front) so no more room in my stacker for any more. I have already modded the top to accomidate the 2x120mm rad, maybe outside the case but I don't really want that 🙁 too messy. I bumped up the 8800 last night and flashed it to 650/1000 & 1500 for shaders. I think I will keep it like that for the default 1.3 voltage otherwise the 8800gtx might start to get a bit . I think I will be happy with 650 though compared to the default 575 .

 

[Mugz]

Mine's on 1.34V, after vmods. That's the lowest I could get it while remaining stable, any lower and I have to drop to 730 on the core.

Mem's probably good to go further. We'll see later on.

 

[Hatman]

If I get the 640mb version, I jsut hope to overclock it to 650/1000.

Theoreticly by overclocking to 770/1080, you should have better on paper stats then a GTX. Would be interesting to see if that was reflected in-game.

 

[jflongo]

I overclocked my 8800GTS 320MB using NVidia's tool.

I have the profile set at

640 Core / 990 Memory

The Nvidia Monitor is showing it actually at

648 Core / 999 Memory.

Just ran 3DMark06 again, got 10070.

Oh and I forgot to add, the card hit the low 70's temperature while 3DMark06 was running. And is sitting in the mid 60's right now without games. So about 6 or 7 degrees hotter than the stock overclocked speeds this card came with.

 

[papasmurf211]

EVGA 8800 GTS 640mb 670/1020 peak 67c.

 

[itotallybelieveyou]

got my 8800 gtx from core 600 to 720 and mem from 900 to 1110 with water cooling and ran stability test on it for 24 hours. though i will never try it EVER again.

 

[Maziar]

nice ^^^

mine : 630 / 950(1900) ,

 

[zdenton]

EVGA 8800gts 320mb

Core @ 650mhz
Shader @ 1.5Ghz
Mem @ 1000 (2Ghz)

Max temp 60C in a 900 case. 3Dmark score - 11480! and thats on vista!

 

[Maziar]

new one : 630/1100(2200)
