Exiled Posted September 1, 2006 Share Posted September 1, 2006 i have a set of XMS2x512mb PC5400 installed on my M2N-E mobo and the os can't boot when i'm setting it to ddr 667 no matter how much i set the Vdimm to(the highest is 1.95V for this mobo). i have also tried loose timing such as 6-6-6-18-2T but all is in vain. i can now only run my ram under ddr533. can anyone tell me what to do to run it at ddr667, please?

Rindigo Posted September 1, 2006 Share Posted September 1, 2006 Hi, I'm just guessing here until someone that knows replys, but have you tried the two sticks in the black slots? And have you tried booting with one stick? Also, what kind of PSU do you have? I run XMS2 PC5400 - 2 x 1024, and it seems to be running ok at the moment on the same motherboard.

Wired Posted September 2, 2006 Share Posted September 2, 2006 so either stick in the same slot will work, but not 2 sticks? Tried different slots? Link to comment Share on other sites More sharing options...

That's right. ddr667 can't run at any setting when dual channel is activated. i've also tried different slots but results are the same. Link to comment Share on other sites More sharing options...
