Hi guys,
Sorry for the long post but here it is ... If the computer is shut down (power supply still on) for more than 4 hours (cold boot), 2 of the 3 memory modules from my F3-12800CL9T-6GBNQ kit don't POST when tested individually. When ALL 3 are installed, only 2GB from the "good" module will POST and be accessible to Windows7-64/Memtest on "cold boots".
I've been troubleshooting this on and off for the past few weeks. I've gone through most of the procedures posted on the net including the one found on the sticky in this forum (http://i4memory.com/ramdetect). I've also exchanged my mobo from an ECS X58-A2 to a much nicer Gigabyte X58A-UD5. I also replaced the Cooler Master Hyper 212+ with a much lighter weight Corsair H50 LCS.
The reason I did this was because I wanted to ensure that there wasn't too much weight or pressure placed on the CPU or socket. IMHO although the Hyper 212+ had good performance to price ratio it also had a poor mounting system.
This is what I get in during POST:
This is what shows in Windows7-64 and CPU-Z:
Memtest86+ shows 3 modules installed but was only able to test 2GB:
Here's what I've done:
1)Updated the BIOS to the latest F5 version
2)Disabled XMP and set the memory to a safe speed of 1066mhz
3)Set memory timings to factory spec of 9-9-9-24 and followed the i4memory.com guide and set the command rate to 2T
4)I boosted the QPI/VTT to 1.315v
5)I removed the heatsink and CPU to check for bent pins in the socket and didn't find any. I made sure that the heatsink was installed with only light pressure on the CPU.
Still as I test one module at a time only one module will POST. The other two modules in the kit don't POST at all. I hit the power button and all I get is a black screen.
Is there anything else you guys can think of before I initiate an RMA? I really need my computer so I'd rather not have to wait for an RMA to process.
Thanks,
