Asus P8P67 Pro Rev 3.1 F3-12800CL7D-4GBECO

[expardo]

Hello,

I'm having problems getting 8GB's of F3-12800CL7D-4GBECO (2x4GB's sets) to post at rated XMP-1600 Specs 7-8-7-24.

I have an Asus P8P67 Pro Rev 3.1 with the latet BIOS Revision 2103 (11/30/2011).

Each 4GB set will post individually at XMP-1600 Spec's but will not post when all 4 sticks of 2GB's are in at XMP-1600 or even JDEC 4 .

They keep defaulting to 1333Mhz 9-9-9-24.

Any ideas?

Thanks!

XMP won't work with multiple sets of DRAM, initially try manually setting the DRAM timings, voltage and CR (2T) with XMP disabled, then may have to raise DRAM voltage by up to + .05 and will Prob need to raise VCCIO voltage to about 1.15
