Hey,
Couple days ago I recieved my Q6600 along with a eVGA 680i, which I was planning on using with my 4gb of OCZ PC6400 (2x2gb). I put everything together, but upon first boot the bios hung, and the onboard display indicated that it was somthing todo with memory, so I guessed (and I had also read about similar problems) that the speed the mobo defaulted too (800mhz ddr) was too fast for the ram to handle at the stock ddr voltage of 1.8v (and aparently my OCZ is 2V), so I put in a stick of Corsair PC6400 I had and volia it booted, so I changed the settings to a lower DDR speed and put back in my OCZ.
Problem is, I cannot for the life of me get the memory to run at 800mhz (which is stock) at the described timings of CL5-5-5-18, and as they're the stock timings, I assume I should have no problem in attaining them.
However, as my CPU's FSB is 266, I set the DDR:FSB ratio linked in sync, so the QDR was set to 1066 and DDR to 533 (well below the stock memory speed), and at this it did boot with both sticks in. When I attempt to move the memory to 666Mhz (so my CPU is running at 333x9=3Ghz) with both sticks in, it just hangs at the bios, but when I remove one stick it works beautifully.
I've tried numerious timing permutations with both sticks running at 666mhz, but they just refuse to boot. Could it be faulty RAM, or is it just a simple thing that i'm failing to notice? As each stick works fine individually at that speed, i assume its just somthing as simple as with more than one stick of DDR the timings have to be loosened for it to be stable?
Any help on the matter would be greatly appreciated
