<br />
<br />
I'm just curious, what else can i do to OC my GPU. And how these speeds are relative to other OC'ed 7800 GT's.<br />
<br />
<br />
So any more info on how to OC some more would be greatly appreciated!<img src="/images/smilies/biggrin.gif" border="0" alt="" title="Big Grin" class="inlineimg" /> <br />

Do a BIOS vmod to get an extra .1v to the core. BEWARE though, make sure you have good temps before you make this mod as it will most likely bump the temps up a degree or two.<br><br>
Here's a guide for the BIOS vmod using Nibitor and NVFlash: <a href="http://www.planetamd64.com/lofiversion/index.php/t15247.html" target="_blank">http://www.planetamd64.com/lofiversi...hp/t15247.html</a><br><br>
Instead of using Nibitor 2.8, go to softpedia and get 3.0a, it's better and easier. And also, read the WHOLE guide (7-8 pgs) before you do the mod as there is crucial information on the last page that will make your mod a hell of a lot easier.

Yes, it's the equivaliency of adding more voltage to your CPU, it helps you boost up your core clock.<br><br>
You should get over 500mhz core on the 7800GT stable with the vmod.

<div style="font-style:italic;">so what exacly does this accomplish, does it allow me to OC further?</div>

Yes it will let you oc further. Before the mod I could detect frequencies at around 490-500ish and after 515-522ish.

Don't always rely on the "detect optimal" button, as it will frequently not work for your games. When I "Detect Optimal Frequencies" on my 7800GT, I get 496/1140 and 2 minutes into a CSS match it dies. In fact, with CSS, I have to run at 480/1080 to keep it totally stable, yet in BF2142, I ran it all the way up to 480/1180 without a hitch.<br><br>
I don't get it...<br><br>
Always test the clock with your games before you settle on that clock. and waht XG drivers did you use?

Hmmm. I can run my 7800GT totally stable at 520/1200. Benchmarks and gaming. The only reason I don't cause it gets a little warm for my likings. I just have the stock cooler. <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin">
