Greetings,
My objective is to use 4x2g F2-6400CL5D-4GBPQ in an Asus Crosshair board.
Specifics:
Board
Asus Crosshair 1.xx (link)
BIOS version 1207
CPU
AMD Phenom X4 9950 Black Edition
Memory
G.SKILL DDR2-800 PC2-6400 (F2-6400CL5D-4GBPQ) (link)
OS
Windows 7 Professional (64 bit)
Traditionally I was using 4x1g F2-6400CL5D-2GBNQ and all was well. After upgrading to Win7 64 bit, I was interested in maxing out the board's potential by using four 2 gig sticks for its 8g capacity.
I received 2 kits of F2-6400CL5D-4GBPQ. Using one stick in slot 1 and 3, it would not boot. Per a suggestion on newegg reviews for this memory, I increased DRAM voltage to 1.9, and all was well.
Attempting to populate all slots results in a black screen/restart at Windows 7 logo/splash.
I tried the other kit, in slots 1 and 3. At 1.9 voltage, those are also okay, and I have no problems.
I have tried increasing the DRAM voltage up to 2.0, but still encountered the same problem.
Wanted to ask the experts before trying anything else. Any help and suggestions would be greatly appreciated.
Here are relevant BIOS pics.
Thanks.
