I understand. But a pencil mod for such marginal performance is probably not worth it unless you want to squeeze the best performance out for benchmarks.
Who knows perhaps it will run at 1200mhz with 1.2v anyway. Have you tried it?

I will not be pencil modding mate just said it be nice, pencil mod seems extreme to me and something i dont want to risk. i tried it and was still getting artifacts but i up my voltage of core to 1.4 will test cod 5 in bit.
You hear people getting the mem to 1200 all time over the net without pencil modding.
I put memory on default whic is 1000mhz for my powercolour plus card, so i am guessing the core is not stable, is it too risky taking the voltage past 1.4?
Go ahead. Keep an eye on the temperature of the VRMs. GPU-Z will have them under VDDC temps. I have a feeling the small sinks Powercolor have used for them may be inadequate without a fan pointing at it.
Also you certain that its using volterra chips? Doesn't look like a reference board. Looks shorter.

I will not exceeed to 1.6 maybe all way to 1.5 and thats it. i have my fan set to auto is that a bad thing for trying to adjust voltage? still artifacts at 1.5. also my card uses the stock 4890 cooler.

I've never taken mine to 1.5v+. So not sure i can give any recommendations on that. Gurusan or someone may be able to tell you if air cooling is enough for that.
Well i put my fan speed to 100% and ran furmark no artifacts shame the 4890 stock cooler is way to loud lol. i proberly need a card with a third party cooler. i dropped voltage to 1.4 at 100% fan speed no artifacting. not sure what i am suppose to be looking for on the vddc temps, not sure what too high would be.

Which card do you have? Was the one I posted above wrong?
Yes, the stock cooler is annoyingly loud. Gaming without headphones will be difficult. I've installed an Arctic Accelero S1 on mine with some fans, which keeps it very quiet. However cooling the VRMs after installing it is difficult. Hence, I haven't overclocked it to the levels I could on the stock cooler.
Some solutions are mentioned in this thread

which should allow higher overclocking with 3rd party air coolers.
My card is this one it comes pre overclocked alittle.
