Problem with Asus P5QC & TW3X4G1333C9


Recommended Posts

Let me start by saying this is about the 10th system I've built using the exact same motherboard, memory, CPU, PSU, video card, etc.. I've never had any problems with any of the other systems. This is the first build that has me going nuts.


When the system was first built, I had a DOA motherboard right out of the box (determined by moving the CPU, memory, PSU and video card to another P5QC). I RMA'd the board back to ASUS. They sent back the same board (as determined by serial number) with no indication of what they did to fix it. I tested it on the bench with only CPU, memory, video card and PSU connected. I was able to get into the BIOS, make some changes and save just fine.


Once I put the board in the case, added the optical drives and hard drive (preloaded with Windows 7, 64 bit, from one of the other P5QC builds), I was only able to get into Windows once for a few minutes, before it locked up.


Usually this system hangs during post. I've tested the modules individually with MemTest86+ 4.00 and no errors. With both modules inserted, if I make it as far as Memtest loading, Memtest just freezes about half way through test #1. No errors are reported, but Memtest is locked up solid.


The system is not overclocked and I'm just using the timings built into the modules (Auto). If I run the system on one of the 2GB DDR3 modules, or a pair of DDR2 1GB Corsair modules, it runs just fine.


I'm at a loss whether I should play with the timings in the BIOS or request an RMA on the memory. It's as if this particular P5QC just doesn't like 2 sticks of DDR3.


Your advice/suggestions would be appreciated.

Today a pulled the TW3X4G1333C9 from one of the perfectly working P5QC systems and put it in the problem system. The system promptly hung at boot. The motherboard appeared to be the culprit. I then pulled a new P5QC out of stock and replaced the motherboard. Installed the TW3X4G1333C9 and the same thing happened (hung during post). Now I apparently have two P5QC's that don't like TW3X4G1333C9. Although TW3X4G1333C9 isn't on the ASUS QVL list, I've never had any issues with many prior P5QC systems and TW3X4G1333C9. Both of these 'problem' boards boot right up if I install DDR2 RAM (TWIN2X2048-6400-G).


I had a similar problems about two years ago with three P5KC systems. I couldn't get Corsair DDR3 at the time and went with OCZ RAM. The systems wouldn't boot or if they did, they would hang or blue screen. Once I replaced the OCZ with Corsair TWIN3X2048-1333C9 the problems went away.

That would suggest a MB or CPU problem, have you checked the BIOS version and if it will support the CPU you have installed? And what CPU are you using and what are the BIOS settings you had set for both CPU and memory?
