Morning all
I've got a new system consisting of the following:
- GA-P55A-UD3 v2.0
- intel i7-860
- Corsair 500W CX PSU
- Crucial 8GB (4x2GB) DDR3 1600MHz Ballistix Memory Kit CL8(8-8-8-24) - BL2KIT25664BN1608
- Antec 300 case
- WD Caviar Black SATA6 640Gb HDD
- Nvidia GE8400GS 512Meg Silent
I'm randomly getting BSODs. This seemed to cure itself after I changed the GPU which was late in arriving, but they started happening again yesterday.
The mesage is MEMORY_MANAGEMENT and technical information is 0x0000001A. A dump file is produced but I have no idea what to do with them.
I figured one of the RAM sticks might be faulty so ran memtest+ without removing any sticks, and it failed instantly.
I'd already noticed that the heat shield wasn't on properly on one of the sticks which was in slot 2 nearest the CPU so I decided to test that first.
I took out all the sticks except for the one in slot 2, and the computer won't even POST. The lights on the board came on and nothing else happened.
So I added a stick in to slot 4, and it still wouldn't post.
I moved those two sticks (let's call them A and B) to slots 1 and 3, and all seemed fine. It booted and I let memtest run for a few minutes.
I then swapped those two sticks out and put the other two (let's call them C and D) in slots 1 and 3, and memtest instantly failed again. Excellent, progress.
I then took stick C out of slot 3, and ran memtest on stick D in slot 1. No problems after a few minutes.
Just to check I then put stick C in slot 1, and guess what? No problems!!!!!
Hmmm. Confused now. Start again
I put sticks A & B in to slots 1 and 3, and left them to run for a couple of hours. They passed 3 times and failed twice.
I then put sticks C & D in, and left them over night. They passed 7 times, and failed 0.
I've now got all 4 sticks runing, and will post the results when I get home.
Questions:
1. Should the board post with RAM in slots 2 and 4? Or must they be in 1 and 3 first? Assuming it should post, I presume I've got a faulty board?
2. Any ideas why 1 RAM stick will sometimes fail immediately, not passing a single test, and then run fine for 7 hours?
I have noticed that the BIOS picks this RAM up as 1333Mhz, instead of 1600Mhz, and this particular RAM is not on the Giga-byte QVL, but Crucial indicate that it works.

Could it be a compatibility issue?
When I first changed the GPU, I ran prime95 for about 5 minutes to see if the PSU might be the problem, but everything ran fine, so I'm assuming the PSU is powerful enough.
Any other suggestions welcome.
Thanks
