Okay I've been griefing for a couple days since I installed Windows 7 Professional 64 bit and I read that I'm only getting 4gb opposed to the 6gb installed on my mobo. I only built this a week ago and noticed it after 7 pro 64bit was installed.
I'm using the Gigabyte X58A-UD3R rev 2.0 with 3x2 Gb of G.skill 1066 (1333mhz) CL9 tri channel memory.
only have installed the original drivers and the factory Bios so its still all new. I've been reading about a few others with the same problems. It consistently says 4gb not 6gb. idk if its instability or what but it driving me insane because i just cant fix it ?
if anyone knows any fixes 4 for I'd be eternally grateful because this is my first built computer and this is the last thing I have to do till its perfect (as i can get it). also the RAMs running at 1070mhz.. I saw it as 1333 maybe I need to OC to get it to that..
Have you gone into your bios and selected profile 1 for memory (Believe its labeled XMP). The should read the memory and set Cl's and voltage to manuf spec. Worked great on my P55 gigabyte board. Note this may change (increase) your bclk and (decrease) cpu multiplier. However the bclk times the multiplier should equate very closely to stock CPU speed.
