Memory Errors!!! HELP!

I built 4 computers that were randomly resetting.

one had a bad stick of crucial pc2100 ram that got over 500,000 errors in memtest86

The nforce one reset until it got the new nforce drivers

and the other two get 1 memtest86 error.


The 8kha+ (1/16/02 bios) with an athlonxp 1800+ cpu, enermax psu, and crucial ram ALWAYS has a memory error at Address 00000410 with ALL 3 sticks of ram. It doesn't matter if it is overclocked or not, or if there is 1 2 or 3 sticks, no matter what, in test 4 or 7, I always get an error at fail address 00000410.

WHY!?!??! Is my 8kha+ board crap? Is it the CPU? The ram has to be good, or I wouldn't get the same fail address every single time with every single stick of ram.


AND why does the k7s5a get a memtest86 error? wtf? I am still testing it though, so I'll tell you more bout that board later.

"-first put the same ram on another working mobo."
I'll try that, but you see, all 3 sticks had an error at the same fail adress about 60% of the time. It didn't matter what stick was in the mobo, or how many sticks were in the mobo.

"-make sure that you stick is compatible with the mobo (maybe you purchased ecc memory and your mb does not support it)"
I made sure before I bought it, they are unbuffered, non-parity pc2100 crucial [micron] 256MB dimms

"-check your memory setting in the bios, also check the memory voltage (if u r not overclocking it should be 2.5 or 2.6)"
It didn't matter if it was overclocked or not, memsettings at normal or turbo, I would still get the same error. The most annoying part is that is that I don't get the error every single time, but about 60% of the time with any dimm. (the test runs continuosly in a loop and after 15 loops, the error occured in the same spot 9 times) It makes no sense and is ticking me off. I think it has to be a bad mobo or cpu.

The author of memtest86 solved it for me:

You are the second one to report this. Evidently the BIOS is using this
location. I think that it is status for a USB mouse. I am still looking
into this but it is not a real error.
