Asus P6X58-E + 12GB Corsair GT Kit

That is correct, after the post beep I power off and right back on. It will show all 12gb as long as I am using the system and during subsequent restarts through out the day. It also shows that I'm using triple channel memory!

Exactly the same for me.

When I shutdown for the night and then restart the next day, I'm back to 8gb. I don't know how long it has to sit before it stops seeing 12gb on boot up. If I let it run with only 8gb registering, it shows that I'm running DUAL channel memory!?!

Normal behaviour, as system only sees 4 x 2GB (4blocks), it assumes you're using DUAL-Channel. Mine does the same.

I do know that I can't push the start button, then hit the reset and expect to see 12gb.
I also tried your cold boot power up, power down and back up, but no luck seeing 12.

Again, exactly the same for me.

Yesterday I had my first crash! I was playing Battlefield, when my screen turned black with some odd flickering in the top. PC rebooted and showed only 10GB RAM in BIOS. Of course I was running with 12GB RAM when PC crashed.

This occured after 2-3 hours of non-stop of gaming, just FYI.

I suppose that a memtest86 session of some hours will lead to no errors.
One idea is that the heavy system stress (CPU + GPU) placed into stress also the PSU. I will be away some days, on return I will try to execute some stress tests that include the GPU (until now only some CPU stress).
One curiosity, what voltage settings do you report on the motherboard? These are my values with program sensors on ubuntu:
Vcore Voltage: 1.21v
+3.3 Voltage: 3.23v
+5 Voltage: 5.17v
+12 Voltage: 12.25v

Sometimes you see 8GB?

I used to see 8GB with the old motherboard, but this new one has never shown me 8GB. Only 10GB and of course 12GB.

Mine, as reported by ASUS's PC Probe II on Win7 64bit:
Vcore Voltage: 0.95v
+3.3 Voltage: 3.30v
+5 Voltage: 5.12v
+12 Voltage: 12.14v

Hi,

Having the same problems as everyone else on this thread. Interestingly I also have an Enermax Power Supply (Revolution 85+ 1250W). This has developed a terrible ticking noise so I have ordered a Corasir PSU to replace it. Installing it on Tuesday so maybe this will help.

My spec is as follows;

ASUS P6X58D-E
Intel Core i7 930
Thermaltake FRIO
12GB Corsair (6x2G CMD12GX3M6A1600C8)
Enermax Revolution 85+ (1250W)
2GB Sapphire Radeon HD5970 OC
256Gb Crucial SSD
X-Fi Titanium Fatal1ty Pro
Silverstone Fortress FT02R-W

I have not yet tried tweaking any of the memory values, but on reading this and other threads it doesn't seem to rectify the issue in a lot of cases. Also I am not an OCer and most of the stuff about voltages goes way over my head! I don't want to cook my newly built machine!!

Will let you know if a PSU swap helps.

Regards

Today I switch on the PC and then immediately I switched it off (less than half a second using the Power button on the PSU). Then when switching on again: 12 GB. So it's definitively not related with heat/warm components.
It's something in the initial power cycle....

Well, I replaced my Enermax PSU (Revolution 85+ 1250W) with a Corsair (AX1200) today. The PC was off for a good five hours while I performed the replacement and on first boot - voilla! 12Gb! Previously after that length of time the PC would only report 8Gb on first boot.

I will see what I get when I boot for the first time tomorrow to see if this has fixed the problem.

Regards.
