ATI Radeon HD 4000 Series discussion

[cstkl1]

was expecting some test results from GAR this morning... concerning how CF performs on P45 (2 x 8 lanes) compared to X48 (2 x 16)...

E8500@4ghz 5x8
Biostar Tpower I45
Team Xtreem PC2-6400 CL3 4x1gb 1200mhz CL5
Sapphire HD4870 Crossfire
BFG Ageia Physx
Vista Ultimate 64bit SP1
Silverstone Op1000

Ati 8.6 Hotfix
PS i had/still have a ton of issue with p45 and crossfire
example random bsod's
NB voltage for single card is +0.1v
for both cards i need to pump up to +0.2v
rams from 2.14v for single card needed to pump to 2.25v
still not stable.. as dreamscene cannot be run in dual monitor always hangs... on stock
but on the overclock setting.. it lasted atleast 10 minutes before hang
