I just put a new box together. I7 930, Asus p6t, 3x2 gb G Skill DDR3-1600. I've manually set timings to 9-9-9-24 and manually set 1600 mhz. I've tried all 3 sticks in all 3 slots, and updated the bios. I've also re-seated the CPU and checked the socket as I've read that that is sometimes the problem.

No matter what, BIOS reports 4 gb, and windows (7 x64) reports 4 gb. CPU-Z reports 3 sticks of 2 gb, all running at correct timings and speed. Anyone have any idea how I can get these to show up in bios?

Read the part on i3-i5-i7 'missing memory':

Can also try typing msconfig in the windows search/run bar, going to advanced options, and checking that 'max memory' is NOT checked.


I did pull the cpu last night and check for bent pins, didn't find any, but I can check again when I get home from work tonight.

I also checked msconfig last night. Max memory isn't checked.

I also ran Memtest 86+ last night and it only showed 4 gb. I guess I'll report back when I get home from work.

Update: I pulled the processor again and found a bent pin. I put the pin back into position, powered up, still 4 gb. I pulled the cpu again and found that one of the contacts on the cpu was tarnished looking. I buffed that up and put it back in, still no dice (original bent pin looked straight on the re-pull too). I'm going to pull the cpu again I guess, but I've thorougly checked that all pins and contacts are clean/straight, so i'm not quite sure where to go from here if I don't find anything.

Yeah, I'm really not an expert on it. (Fortunately my i5 worked fine). It is always possible that something got damaged. If after another look you still can't find it, might want to RMA at least the board.

I called asus before going to newegg for RMA. Tech guy ran me through a couple bios settings and said it was a known issue send both the board and cpu back to newegg. Sitting now waiting to ship out.

Glad tech support from Asus could help you out. I was wracking my brain trying to come up with some other things to try:-) Good luck with the RMA

Yeah, this is a pretty widespread problem. Glad to see they recognize it is and were efficient with your request. Asus support always was good to me.
