good evening fellow black pearl fetishists,

i recently swapped my deluxe for a premium and promptly cleaned out the gunk from under the heatpipes & lapped a fresh SLACR.

i previously had a p5w with e6600

my problem is that once I exceed 9 x 380mhz my 3D mark score drops from 13000 to just 4000.


ram is 1:1 with FSB
vcore : auto 1.40
dram voltage: 2.10

i've played around with it all day and reinstalled the drivers, it does the same under XP or vista x64.

any idea what i'm doing wrong here? i can't see anyone else complaining about a 3D wall > 380mhz.


system is as follows:

antec 900 case
silverstone st85zf powrer supply
p5k premium
q6600 g0
2 x 1gb gskill F2-6400-PHU1-GBHZ
sparkle 8800gtx
x-fi music
1 x 36gb raptor
2 x 400gb seagate
pioneer 212
thermalright t1-128 heatsink with 120mm fan

cheers, limb0
