Hello, I'm having trouble getting the RAM to run above 1866. A year ago, I made a post here http://gskill.us/forum/showthread.php?t=12406&
In that case, I was starting with the stock BIOS. At that time there was a BIOS update, which I installed. Afterwards, I was able to run at 2400 on the i7-3820 using the default XMP2 profile with no issues and have been for the last year.
I just upgraded to the 4930k, and in the process, was required to update the BIOS to one of the 2 latest revisions in order to use the ivy bridge e CPU. Since then neither of the 2 XMP profiles are working again. I tried entering some settings manually to no avail. The best I was able to achieve so far was by setting the BIOS to the XMP2 selection, then changing it to manual and tweaking the multiplier down to 1866, the trfc to 255 and the trc to 43.
The settings Im using atm are:
Stock CPU speed
tCL 10
trcD 12
trP 12
tras 31
trfc 255
twr 16
twtr 9
trrd 6
trtp 9
tfaw 26
trc 43
cpu vcore 1.25
vc csa 1.25
dram 1.65
Would any other BIOS settings enabled or not, be affecting this? Since I was running at 2400 fine with an older CPU I figured it must just be a subtle issue with the settings. As before, any help on the matter would be greatly appreciated.
