I just bought some red G-Skill 1600 RAM (3 x 2gb) that are XMP ready. For some reason in the BIOS, the XMP profile shows up but is greyed out and set to AUTO instead of the 1600 profile. Because it's greyed out I cannot access the profile. I manually adjusted the timings as well and this did not work. (9-9-9-24)
Also, in my DRAM Frequency setting, it only shows options to run at 800 (400mhz) or 1066 (533mhz), no 1600. I had the same problem with the OCZ Gold but I thought it was because it did not have XMP.
I'm using an ASRock x58 extreme motherboard with a Xeon x5570 engineering sample processor (B0 stepping). The processor does have an unlocked multiplier and the ASRock BIOS does support the CPU. Could the CPU be the problem here?
I can run older BIOS (1.90) and there is a pre-made setting to OC the ram to 2000. When I do this, the ram runs at 1200 (600mhz) and the cpu goes from 2.93ghz to 3.35ghz and will boot up. When I try to use the easy OC setting to overclock the CPU to 3.6, system does not boot. halp
Yep, unfortunately with the move of the memory controller from the motherboard to the CPU, the motherboard now has little say in the memory speed, it is all up to the processor.
As long as you manually set voltages to defaults, you can't really hurt the chip.
What you will then have to do is set the ram to the highest multiplier, raise the bclk a little, and lower the CPU multiplier and QPI multi one notch. Then go into windows and run prime95 for 10-20 minutes. Then back to the BIOS and keep increasing the bclk until an error or bluescreen. Then reduce the CPU multi...etc.
