780i with 4 dimms no post?

03-29-08, 11:52 PM

I got some Corsair Dominators (TWIN2X2048-8500C5D 4x1GB) in a trade today and I attempted to install them in my EVGA 780i board however I can't get the board to post. Well I should say it post when it wants to, once it posted I couldn't get the system to boot into windows with the ram running at 800mhz. Is this a BIOS issue, or simply populated all banks with ram issue?
Anyone else have similar experiences?

Also I heard that the 780i cannot has issues running 4 dimms @ 1066mhz or faster, is there any truth to this?

Not sure about the reference boards, but tons of people experienced issues with 1066 RAM on the Asus 780i boards. It could be BIOS related. Try increase your SPP/northbridge voltage to 1.4V, and vdimm to 2.2V or 2.3V and see if it helps. Also make sure you disable SLI Ready Memory in BIOS and set the timings manually.
