I just got all the parts today to build this new computer, and so far it's been nothing but a headache. After trying for several hours to figure out why it wouldn't post, I finally jiggled the RAM and now it's posting ... but it's only seeing one memory module. I have 2x512mb sticks in there, and both register individually, but putting them both in won't show as 1 gig. The motherboard is an ECS RS485M-M, and the memory is from AData, dual channel DDR2 800. I'm not sure what, if anything, I can do to fix this, or if I have to send it back and wait another week before I can get this system up and running... any advice? Is there something I might have overlooked? Thanks in advance!
