Hi, I saw a post about the 'asus m2n sl'i motherboard on here and thought i would ask for some advice or help. I have recently bought more RAM for my computer, hoping to add the RAM i had already, however after trying to insert the new RAM into the black DIMM slots for dual channel they wouldnt insert properly, so i started thinking "oh no ive bought the wrong one", but then i removed my old RAM from the yellow DIMM slots, put my new stuff in and they fit and work perfect... so my problem is that none of the RAM i have will fit into the black DIMM sockets... despite them both being 240pin, 800mhz, DDR2. They just wont slot in enough for me to click both clamps down, if i manage to get the bottom of the RAM inserted so it clamps in, the top end will sit up and if i get the top in, the bottom end will sit up and so on and so fourth. I have done a bit of research and all 4 sockets, yellow and black are supposed to be DDR2 sockets 240 pin. So why wont it take the RAM ive got?
