Ram won't run in dual channel Tags: Memory RAM Dual Channel Last response: March 29, 2009 5:54 AM in Memory Share oldpuggler March 28, 2009 4:06:58 AM Hi all, Got a problem that I have been struggling with for a few days. My setup first: ASUS M2N-X mobo AMD 64 X2 6000+ Processor AMI v02.58 BIOS ASUS EN9600GT Graphics Card Seagate 250gb Sata Western Digital 120gb IDE Crappy Shaw 550W PSU So I bought the system from MSY over a year ago with 2x1gb DDR2 Generic 667 sticks of ram. The system was running dual channel fine. I upgraded to a Super Talent 2x2gb DDR 800 sticks of ram. Now my mobo will only recognise 1 stick of ram. I have even replaced the original 2x1gb sticks and cannot for the life of me get the mobo to recognise dual channel again. Can anyone help me? I have attached some pics of my BIOS settings, can anyone teel me what I have to do to get my mobo to read dual channel again???? http://img19.imageshack.us/img19/1632/p3280676.jpg http://img19.imageshack.us/img19/7758/p3280675.jpg http://img27.imageshack.us/img27/7239/cpuscreens.png Thanks all!

Try your old DIMM in the same slot as the one it won't recognise is now. Can't find your answer ? Ask ! Get the answer oldpuggler March 29, 2009 5:54:02 AM Hey all, thanks for the replies. I too thought the mobo would only support 2gb ram as per my manual, but I found this: http://www.asktheramguy.com/v3/showthread.php?t=76273 and this: http://www.asus.com/Product.aspx?P_ID=gg77EtrKL4nFw1DU&... Which says it supports up to 4gb. I have also had the 2x1gb sticks working in dual channel, but when I even revert back to those the bios is only picking up the single channel? Any other ideas/thoughts? I only have two slots for the ram to run in so I'm pretty sure they are in the right slots. What are the pipelines? Are these replaceable? Can't find your answer ? Ask !
