Overclocking 8600m gt shaders...

Im Asus C90s user with a 8600m gt ddr3. Everytime I overclock my video card and get to a certain core my screen gets funky. So I ve been messing around and found out that I can push the shaders higher then the core. This gave me a extra 300 to 400 points in 3dmark 06. For people with the ddr2 card that have 550 core / 500 mem, could anyone just try to push the shaders higher and see if it makes a diffrence for you too? Leave the core and memory at the same place.

 

let me start by saying do not overclock the vga!
if it fries good luck getting a replacement if it is out of warranty. best advice anyone can give you is DO NOT overclock unless you want to be stuck with a paperweight

 

not true.. maybe for integrated cards.

the 8600m is easily overclockable and will stay well within reasonable temps

 

people have been overclocking on the forums for months... if you know what you are doing you should be fine

no one is resposbile for what happens except the user... I think people know what happens to their warranty if it fries. People do it at their own risk. I was just pointing out a possible preformance boost.

 

Correcto!

It's somewhat safe to OC as long as you stay within safe margins...

What are my safe margins you say?

Well experiment in 5mz increments until you start seeing video artifacts. One recommendation though, once you reach what you think is your top speed, lower it say 10-20Mhz since GPUs tend to perform better when a bit below top rates.

Also, don't take other people's successful settings as your final settings since no single GPU is the same, some withstand higher rates than others, even when they are the same brand, maker, model...

Yeah my 8600 OCs for crap...

I'm praying for a new card to replace it soon, especially since the 8600 has rapidly become just a standard card and is no longer hailed as an awesome gaming card. It's good, no doubts there, but not great. Anyways, abck to my card.

For some reason pushing it higher than 525/450 causes lots of problems but perhaps overclocking the shaders instead of just the core will help. I actualy do use dx10 mode for hellgate london (on the rare instances i play it...) and im surprised at the frame rates I get when overclocking - theyre great. With all settings at a high level at max native resolution I get 25fps on average. Not great for fps games but just fine and dandy for an rpg. The game looks amazing as well. But on battlefield 2142, I get fairly depressing frame rates even at medium settings and even with OC. It's like my card prefers dx10 mode to dx9...weird...

 

On my G1S I can overclock all the way up to 575/780 and get almost 4680 3Dmark06 points... But I prefer to OC at 500/740 since I can play for hours without generating more noticeable heat.

I haven't tried HellGate London yet, but on HalfLife2 Episode 2 I can play at full resolution which is 1680x1050 with all effects enabled on highest settings at a very comfortable ~30 FPS
