I have updated the bios to the most recent via the Intel website. I have tried utilizing both XMP profiles and neither will boot. I have tried inputting the timings manually and it still wont boot at 1866. The only way I got it to boot in 1866 was with manual timings and 1.55v The problem with this is it was unstable and had 700+ errors in memtest86 and hung at test 6. It can't even get through all the tests.
Anyone had experience with similar issues on these RAM. Am I SOL and have to live with it at 1333?
