andreaplanet Posted September 22, 2010 Share Posted September 22, 2010 I have the same RAM and Board but on cold boot only 10GB are detected instead of 12GB. If I switch off the PC after half a second (or longer) while cold booting then the next boot will recognize all 12GB. So I don't think it's a heat issue. Memtest+ 4.0 does not report any error and the system runs fine, never had a crash (2 months old). I tried to set manually the voltage using various values, I tried to use XMP, I tried with the latest BIOS (XMP settings changed somewhat with the latest BIOS) but still I have to do boot twice to recognize all 12GB. Unfortunately I can just make one test x day because all subsequent boots will read 12GB. So, my question is, which are the optimal settings for this RAM, Board (no overclocking)? After enabling the XMP Profile what settings do you have in your BIOS? Link to comment Share on other sites More sharing options...
