I just completed my first build I7 920 on ASRock X58 Extreme, installed 6GB of OCZ OCZ DDR3 1600 MHz Gold RAM, everything looks good after installed Windows 7 64-bit, except I only see 2GB in both POST & Win7 computer property, despite cpuz shows 6GB available. I've updated the motherboard with the latest version of BIOS from ASRock (v1.40, released on 9/8/09) but it didn't help.
At POST, 2GB was shown as installed in B1 (white), the other 2 sticks on A1 and C1 (all white) were missing, I've tried to putting different sticks in different combination on A1 & C1, the results were the same that only 2GB were shown, if I put the memory in A1 & C1 only the computer won't even boot.
So to me, I probably got a bad motherboard that memory on A1 & C1 doesn't work. Any other thoughts or things I should try?
Yes, I'm going to RMA the board. ASRock tech support also suspects problem with it.
Yes, the sticks are in correct slots, and I've tried all possible combination of 1 stick, 2 sticks and 3 sticks with different stick in different slots, only the stick on B1 is recognized.
Hi I have the same , problem, my mistake is that i did not documented myself well enough before buying the MB.
did you solve anything with this MB. i am planning to buy Vengeance™ — 6GB Triple Channel DDR3 Memory Kit (CMZ6GX3M3A2000C10) . and, also a few bios updates have been done, regarding the triple channel memories.
