Hellraizer Posted September 29, 2010 Share Posted September 29, 2010 I have problems with my Gigabyte GA-X58A-UD5 (rev 2.0, latest FB BIOS) and my two pairs of CMT4GX3M2A2133C9 (8Gb total). System doesn't start with XMP mode on. Manually entered 2133MHz (16.0) and timings 9-10-9-24, and ofc voltage 1,66 (there's only 1,64 and 1,66 in BIOS, but 1,65 neeeded) - parameters that printed on modules. It starts, but sometimes 'looses' 2Gb of RAM on start or reboot. Sometimes even more. No dependences, works unstable. Tested with 3 modules of 2Gb - same thing. Installed Win7 x64. It works, but sometimes goes 'memory' BSOD. After reset - 'memory loosing'. Tested with default BIOS - works 'better': default tests of Memtest 4.10 are OK, but when I try 'resize mem' test - lots of errors and freeze. Don't know about my power supply. I have ******** PurePower RX 600W, I think i'ts enough, but maybe I'm wrong. Tried with HDD and CD off - same problems. Maybe BIOS manual tune was not enough and I forgot few parameters? Any advices? P.S. Sorry for my bad English. Link to comment Share on other sites More sharing options...
