Deadboy90's GPU Overclocking guide

[.PoNeH]

Couldn't test it last night, but I can guarantee you that 3dMark is whitelisted. Why would the GPU throttle back even when not OC'ing it?!

Run Kombustor and check the clock/shader/memory speed on the right. let us know what they read.

Thanks deadboy, running around with The Witcher 2 on 530/1272/851 and after over an hour, no freeze at all. Get around 25-30 frame/sec on the prologue battlefield (lowest settings and 720p resolution of course). GPU temp is about 60*C
OC gives me about 5 extra frames, which turns from lag and frustrated to playable

Okay... so if overclocking the memory too high is what causes the artifacts, what issues come up from overclocking the core/shader too high? Is it just temperature increases?

It might cause further downclocking (driver crash), BSOD or application crash

yep, right on the nose. However after some testing I have found that the memory is the most importiant factor in OCing. While running Kombustor I overclocked just the memory and got 5-6 fps increase. Then i put that back to stock and OC'd the shader and core and got only 1 fps increase. Then I tried both and got 7-8 fps increase over stock. So yea, memory OC has the most effect of FPS.

all GPUs are different and some OC higher than others, yours clearly cant go that high so you need to try a lower overclock. (And try and find AJslays GPU BIOS mod, it gives the 335m more powers so you can overclock more.)

where i can find AJslays GPU BIOS mod? please guide me. i want to overclock my gpu

You can Overclock without it, just try that first. slowly move the sliders up 5-10 mhz at a time and test the overclock with Kombustor. if it's stable then move it up again 5-10 mhz more untill you find the settings that you are most stable at. If you wish to jump right in then you can try 550/1350/875 and go from there.
