Hi, this last week i have tryed to get me newly bought memory to work with little succes.
the thing is that the computer workes just fine with both memorys one at a time, but when i plugg in bos to run then att dualchannel i just get a black screen and all fans starts. i guessed at fisrt that i dident have enough power for my new gear so i bought a coolmaster 650w which should do. i have tried to raise the voltage to the 2.2v its rated for and changed the timings too. worth to say is allso that is i plugg them in wrong i do get the beeps that sayes i put then in wrong :P. it would be nice to get my 2 gigs running.

any help that might solve this problem is appreciated

Sounds like that there is something wrong with the memoies if you can either exchange it with us or exchange it with the vender the next set of memory will work on you system.
