Just registered to say thanks!

One build needed the screws loosened on an i7-920/ASUS P6T/12GB. The two DIMM slots furthest from the CPU were both not being detected, so I figured it was just overtightening after reading the OP by George. Sure enough! Loosened a half turn on each of the CPU screws on that side and voila! 12GBs upon boot.

Second build was an i7-980X/ASUS P6T/24GB. I had not realized that i7-980x should use 1.66x-1.8x Un-Core for optimal voltage for the VTT and vDIMM. I knew I should not need that high of vCore/VTT to be stable @ 4.3GHz. Lowered the Un-Core ratio and my OCCT test is happily hammering away

Loosened a half turn on one of the CPU screws and I detect my full 6 go .. see tomorow when i will reboot if it is finally the solution ! hope so !

today only 4 go ... grrrrrr

soon i will remove my motherboard and see if there is not something wrong behind it !

I did also get less memory than I should so I did set all timings manually:

DRAM Frequency DDR3-1600MHZ.
DRAM CAS# Latency 8 DRAM Clock
DRAM RAS# to CAS# Latency 8 DRAM Clock
DRAM RAS# ACT Time 24 DRAM Clock
DRAM Bus Voltage 1.65V

I ran a memtest and got this as a result:



Do you guys think there could be something else that also causes the problem because I'm reading this right now:

http://i4memory.com/f54/asus-x58-6-1...stalled-19200/

This is the system I got (assembled it last week and did RMA the memory this week):

Asus 1366 P6X58D Premium.
Intel 1366 Quad Core I7 930 2.8GHz BOX.
SAPPHIRE HD5970 2GB GDDR5 PCIE.
Corsair DDR3 6GB 1600MHz (3x2GB) XMS3-1600 CL8-8-8-24.
Western Digital Black 500GB.
Corsair PSU TX ATX 850W 24P 12cm Fan.
Win7 X64 Ultimate.
Cooler Master Hyper N520
Antec 900 two case.

I can't use it right now because I have no memory atm :-p. The first time I booted the system I had it detecting 4GB instead of 6GB. Then I set everything to default in the bios and seemed to work for 2 days. Then all of a sudden I got a bsod in Split Second Velocity.

De computer is opnieuw opgestart na een bugcontrole. De bugcontrole is 0x00000116 (0xfffffa8005bb4010, 0xfffff880047b7c48, 0x0000000000000000, 0x0000000000000002). Er is een dump opgeslagen in: C:\Windows\MEMORY.DMP. Rapport-id: 062910-15615-01.

I first suspected the graphics card as it crashed on the ati driver. But I also had it lock up once on windows update and then completely freeze on counter strike source the day after and saw it was detecting 4GB instead of 6GB again.

All my system temperatures are ok.

I suppose I will receive the new memory somewhere next week.

Bayron welcome, see what test #6 could be related to http://i4memory.com/f79/memtest86-v4-10-a-6/

awesome thanks for the feedback, always good to know when my findings help others

@eva2000

Thx for the info when I get my new memory back I will test it again with the latest version off memtest86+. I really hope it is the memory itself. I should check it out but I think the backplate of the cpu cooler has some protection pads on it, so I suppose that is not shorting the motherboard. I also hope the bsod I had in Split Second is related to that and not the graphics card. Because I really don't want to have to RMA the graphics card...

I have similar issue with memtest failing. I keep reading about the mem controllers on X58 motherboards and cpu heat sinks causing issues.

If I lay my computer tower down horizontal so that heat sink puts even pressure on the cpu, memtest passes. When I put my tower case vertical I will get memtest failures. I've put extra washers on the backplate and everything seems snug. I'm thinking maybe the motherboard socket is extra sensitive... don't know what to do now I've tried 2 coolers, maybe I'll put the loud stock cooler back in.

So before I get the memory back I added some extra washers (The red paper like things, I also used on every screw that holds the motherboard) to the backplate of the cpu cooler. Although when I got the motherboard, the box wasn't sealed. If it still doesn't work I don't know what I can do more.
I also added the manual to show that the cooler is fitted properly:



I hope these small wachers will be enough even though it already has some protective stuff on the backplate. I'll test the pc overnight with OCCT and memtest86+ and everest and prime95 and Furmark when I get my memory back. I just hope the BSOD I had in Split Second Velocity and the freeze I had in CSS have to do with this. Because if I also have to rma the graphics card it's like a nightmare.

pins are meant to be that way in the socket they aren't straight pins exactly. When folks mean bent pins they mean not structured the same angle/bend as the rest of the bins - i never experienced bent pins on boards though

p55 cpu socket photo here http://img2.i4memory.info/reviewimag...dk_p55_83.html but basically same as x58 as to how the pins are structured





i'd just double check if any of backside solder spikes pointing out the board are touching or shorting the backplate and/or motherboard case etc

Also for photos might want to use IMGFS instead of IMG tags to keep widths to 800-1000px max see http://i4memory.com/f5/feedback-addi...img-tags-6081/
