Greetings,
New (upgraded) 780i with 4gb Corsair 8500C5D... One pair was purchased over a year ago version 1.1 Micron D9's... they have always run at 1066 2.2v 5-5-5-15 2t... STOCK no isuues!
I get a second pair version 4.1 and when run by themselves they run with no issues as the first set STOCK...
When I put the 2 pairs together... They won't run over 800... and SLI mode is "not detected"...
I've run mem test on both pairs... no issues
I've installed the Vista hotfix for the 4gb thing... no blue screens or freezes... If I try to boot with all 4 sticks at 1066... it boots to safe mode only! @ 800 it boots fine...
I've double checked voltage (2.2v)
I've reset the CMOS
This is also whether the CPU is OC'd or not...
Bad board? or bad RAM?
any ideas?
Thanks
