Dud memory?

[Impaler]

Hi I was hoping someone could give me some advice. I noticed that the new version of opera kept giving me memory read/write errors. I tested it with memtest86 overnight and seem to have developed some errors since when first installing the machine.

Here are the results I get:

WallTime Cached Rsudmem Memmap Cache ECC Test Pass Errors ECCErrors
~9:00:00 512M 84K e820-Std Off Off Std 41 4 0

Tst Pass Failing Address Good Bad Err-Bits Count Chan

5 41 000040f8be0 - 64.5MB 01000000 01800000 00800000 1

I typed that in so the formatting didnt quite work out. I dont have a great deal of experience with this utility but it seems to me that the memory is coughing errors say every 1/20 passes which suggests either dodgy seating/connection of the RAM or dodgy memory itself. I am going to swap channels tonight and see if there is any difference. This was also the second time I did this after the first time I returned the timings back to specification (2,3,3,6) rather than the slightly more aggressive ones I had given. I recently replaced a faulty northbridge fan with a more powerful one that I admittedly have modified to fit. Other than that nothing has changed hardware-wise for some time and it is winter here so cooling should have got better.

Anyone have any suggestions on the cause of this?

Specs are a Barton 2500, nf7-s and the memory is a matched pair of 256MB OCZ 400MHz modules.

Thanks for any suggestions and help.

For anyone interested, changed the memory banks over and after 50 passes didnt get any errors. Looks like the memory just had seating issues.

Will run memtest and prime again to make sure in the next few days.
