I have two OCZ Platinum Revision II 512 MB modules on an ABIT IC7 G motherboard. The memory is running at 2.8v (recommended by OCZ) and is not overclocked. The system has rebooted on its own a few times, so I suspected the memory might be the problem. Heat is not a problem since I have a humongous CPU cooler and a Thermaltake HR6 on the northbridge and Speedfan shows everything to be as cool as a cucumber.
Sure enough in an overnight Memtest there were four failures recorded. That is out of almost 60 passes --but a failure is a failure. Now for the odd thing I am asking for help in understanding. The four failures all occured in Test 5 with the same error pattern in all four cases: 00001000 was read as 0000000. The strange thing is that although the errors all occurred in the same test (#7) and with the same error bit pattern, they each occurred at a completely different address. If there was a bit hanging -- either way -- at the same address I could understand it, but to have the same bit pattern occur at different addresses I can't figure out.
The test shows that an error, in Memtest, occurs only very rarely, but that is about what was happening in the random reboots. The machine only rebooted every few days, and then only once when it did.
Any insight would be much appreciated.
