Bad RAM, or bad motherboard?? Help...

post #1 of 6
Thread Starter 
Over the past few days I have been coming into my room to find various BSOD's. "MEMORY_CONTROLLER", "PFN_LIST_CORRUPT", "BUGCODE_USB_DRIVER", "IRQL_NOT_LESS_OR_EQUAL" and one other I can't remember. Never the same thing two times in a row...

I run memtest86 immediately after a BSOD and it usually shows errors. I run both sticks, it shows errors. I run one stick, and can usually find at least one of them "bad". I have four sticks to play with and have only been running two of them for the past several weeks. I have tried running them at 1.9v, 2.0v, 2.1v, and 2.2v. (Ballistix PC8500...specs call for 2.2v). I have a 120mm case fan sitting an inch away from them blowing directly on the memory for heat control. For weeks I've had no problems. For the past 4 or 5 days, 3 of my 4 sticks test "bad" when I run them individually with memtest86.

A few minutes ago this is what I saw:



I have never seen this before. It usually goes straight to the windows screen after the "verifying DMI Pool Data/Boot from CD" message. The machine locked up after the "DHCP" appeared and I had to power down and reboot. Is that message still something that has to do with bad memory, or do I need to start looking at the MB? It's just weird that 3 mem sticks would die over 4 days when I'm running the suggested voltage....or less. I've already RMA'd one stick several weeks ago when the machine acted like this a bit....and the new stick is one of them that now tests bad.

Any suggestions? Is the ballistix ram just crap, or is my MB doing something it shouldn't be doing?

BTW, this is the type of thing thing that shows up when I run memtest after a BSOD:

I am going to vote on RAM. When mobos fail they usually don't post.

After a BSOD, I sometimes have to power down several times in a row to get things running again. MB beeps at me and says something about a bios error and not detecting a floppy drive. 4 or 5 power downs later it will get to the point where I can go to the bios and make changes (usually resets most of my timings and voltages).... Does this make any difference in what might be wrong?

Yea the ram could be causing your board to reset to stock thinking your settings are unstable. Like when overclocking too much.
Could be causing the board to do odd things I suppose.

Just an idea

DHCP is Dynamic Host Configuration Protocol. It assigns your IP address and other aspects to your internet connection.

The USB and DHCP errors could be related to a new router or just the need to reinstall your motherboard drivers from scratch. Have you changed your internet provider or added a new piece of hardware recently? This could be conflicting.

If you havent added any new hardware or internet related software... Try reinstalling your motherboard drivers. Worse case scenario reinstall Windows and start again.

Ram errors are probably related to your OC. But id see whats causing the conflict probs first.

I'd pin it to the RAM, motherboards rarely fail in this way (usually they just go kaput when they die). Bad RAM causes lots of problems everywhere (just think... what would happen if you had no short term or long term memory?)

Usually IRQL_NOT_LESS_OR_EQUAL comes up with a bad video driver, but I suggest you isolate the issue first and try booting with the single good stick you have, and then troubleshoot from there
