Not for me, solid gains from 1200mhz to 1400 in heaven benchmark.
There is something that I have found to degrade performance though, fan profile polling interval of msi afterburner causes lag severely.

VR001 is a heatsink kit. Since the VRMs are oddly placed compared to other cards, and the base of the heatsink for the TTP doesn't touch the memory chips, you need to put heatsinks on them.

what he was trying to say is that you need one of their heatsink sets that is marked as VR001.

http://www.arctic-cooling.com/websho...ath=2_&mID=619 see near the bottom where it says VR001 then next to it it says buy now? thats what needs to be added to the cooler to make it work properly.

as you can see it says it comes with ram and voltage regulator heatsinks. though oddly enough its the only one that does not say it includes a mounting bracket.

Guys, I need your help!

With 1000/1200, my 6870 will only score 16K at vantage while it should score around 17K+. (On performance)

I noticed that during Vantage my Gpu Usage sometimes falls around 70%... I thought it should be 99%/100% during the whole benchmark.

Don't you think there's something wrong?
post #1108 of 6939
i think so.

However a PH II shouldnt Bottleck a single 6870

MacA are you using any sort of stability testing software or just overclocking and running 3dmark?
