Dual Channel Memory problem
so i had an 512 and a 1 gb of ram, and they both were pc2 5300, so i went out today and got another 512 and 1 gb of ram.
when i try dual channeling all of them, my computer wont start, not even a post beep. when i try the 2 512 together, it was still single channel and it only showed 512, when i try dual channeling both the 1 gb, all i get is just doing long beeps.
all rams work with single channel.
i have an DFI infinity NF ultra II M2 motherboard with an amd 64 X2 4400+.
