Memory problems, think it might be the Athlon 64 memory controller.

Hello all,

I'm having problems with the memory subsystem on an Athlon 64 rig I built this summer. The computer is my dad's, and he has been complaining for a while that the computer does random weird things and crashes. I just got home for break, so I'm testing it out.

Most of the time it works fine in Windows, but it has random occassional crashes. One of the first things I did was run Memtest. Memtest started getting errors, all of them in the area of memory more than 1000Mb. It also crashed after about 2 hours of wall time. I figured it was the memory, so I switched it out for some other memory I have. I ran memtest again, but I'm still getting errors, this time in memory 900Mb and up. It has gotten 30 errors in 4 hours of wall time, but hasn't crashed yet.

I'm wondering what else could be causing the problem. Could it be the memory controller in the Athlon 64? I don't think the motherboard or northbridge has much to do with memory in an Athlon 64 system. I don't have another S939 proc or motherboard, so I can't test it. What else shoud I try?


Cliff Notes:
Computer doing funky stuff.
Run Memtest, get errors and crashing.
Change Ram, Run Memtest, get errors but no crashing.
Wonder if problem could be in Athlon 64.



Thanks for you suggestions,
Swan
 
If the ram fails memtest try uping the voltage slighty to the dimms or the processor and then run it again if this isn't an option try relaxing the memory timings then run memtest until it passes, if you still can't get it to work you most likely have bad memory.
 
remember overclocking doesnt kill but voltage does! The first thing i would do is to lower the ram to 333mhz. Try that... Also remember that higher end 939 mobos dont run value ram well at all. It will give errors and wont run 1:1 at 200.
 
This RAM did work fine up until a little bit ago, so I don't think it's that the board and RAM are incompatible. The original RAM is mushkin basic, which is nothing special. The other RAM, however is Corsair XMS Platinum, so it is good stuff. Both have problems.
