8800GT Overclocking.

post #1 of 8
Thread Starter 
What is the highest the 8800gt can be safely overclocked to?
I know that it varies from card to card, but what are the highest overclocks you have seen?

Also I know there is a bios volt mod, how much would this increase your overclockabillity of the card?

Basicly, list the highest stable overclock you, or someone else, has seen/obtained.
Also list if you used a volt mod, and lastly list your GPU cooler, whether it be stock or aftermarket.

This card really isn't too overclockable with everything stock. The highest I've seen is 800mhz with vmod...but that was a hardware, not software mod.

Generally you can get to ~680 ish on stock cooling, really the voltage is an issue here...

I think 700 is attainable (or slightly lower) with software vmod, but don't expect too much.

Really the GTS is a better card (I doubt you want to hear it though, you have the card already ) and overclocks to 800 on stock ^_^...

GL with the ocing though

i can get 730/1805/2050

I need a cooler though soon as she touches 63c it locks in games
But I'm not spending 50 on a cooler so i can do 720/1805/2050

Oik I forgot to post my overclocks..

During normal use I am at 700 core/ 1750 shader/ 975 mem (x2)

The highest stable I have got this card is 750/1900/1030 (x2)

This is without a Vmod. I don't bother keeping my overclock that high all the time because I don't need to lol..

By the way I'm using an accelero S1 cooler, highest temps I get are in the very low 50's.

My card is a PNY card with the Qimonda memory chips (another reason why I don't keep my memory clock too high, I heard they aren't very good mem chips.)

Might I suggest running the Rivatuner graphs, or the GPU-z tool, while you are overclocking, so you can see what your card is actually running at? I don't believe the 8800GT is capable of running at *ANY* of the six clocks you mentioned above. Yes they are all in the ballpark of the actual values ... if memory serves, what you're actually running 'normal use' is 702, 1728, 972.

Try using one of those tools and you'll see what I mean ...

Here are some screenies.. I didn't go to 750/1900/1030 because I don't have the patience right now to move it up slowly . Here you go. I ordered this card from Newegg. It is the PNY stock card. (Accellero S1 heatsink added).

I would have ran atitool longer but as I said, am impatient atm. But yeah, the 702 core one is what I run at 24/7 and use for my gaming.
