Testing memory

[J22]

How certain can I be that my OCZ PC3500 Performance Series (2x512) memory is bad if it fails memtest86? It ran OK at 166 mhz, but generated 1000's of errors at 185 and 200. I tried each stick by itself, but both generate errors and eventually lock up memtest86. Even though I think the memory should run at its rated speed and timings at rated voltage, I tried increasing vdimm and loosening the timings. No luck. Any chance that the MB (NF7-S v2) or the CPU (XP 2600+Mobile) is causing/contributing to my problems?

Anyone???

Well, obviously *something* is wrong, but without known good memory (or a motherboard/CPU known to run stably at those speeds), you can't be sure what. I'd tend to blame the memory here (that's a pretty solid MB, and the newer XP CPUs are very reliable), but there's really no way to tell without swapping it out.

Didn't you post this on the cpu/oc forum? Use 1 dimm at a time, systematically try different slots. Start with slot 3 first, then two, then one. If a dimm can't run at 200fsb in any slot, rma-replace the dimm. if you find one slot is faulty, rma-replace the mobo.

It could be possible you have a bad slot but not likely. If the memory failed memtest86 I would get it replaced. If both modules failed I would become suspicious the slot might be bad. Try putting the modules in the second slot and run the test again.

Failed memory test=bad memory.
