memtest

I've been given four 1GB Corsair DDR2 memory modules, and am trying to fit them into my computer but am getting BSOD on Windows XP and errors in Memtest86+.

I've tried to identify if one particular module is faulty by trying them in pairs. They work fine in pairs, but when all four are inserted, Memtest86+ reports errors.

The motherboard is an Asus P5N-E with dual channel support and the modules are all the same model (same speed, capacity and timings) but one pair is a different hardware revision. One is v2.1 and the other is v2.2... the voltages are the same too. Would this minor difference be a possible cause of the problem?

I've got the BIOS memory timing settings all at AUTO - should I manually set the timings?

memtest incorrectly recognizes my RAM

I recently built a computer and randomly got a couple blue screens. I've run memtest and one of the memory sticks consistently throws memtest errors, while the other does not. The odd part is, memtest lists the following settings for my RAM: RAM: 535 MHz DDR 107 / CAS 2.5-1-3-1 DDR1 128 bits But… >>> More

Bad Intel DQ965GF motherboard? Fails memtest, but memory is good.

as seen on Super User - Search for 'Super User'
I've got a machine with a DQ965GF motherboard. Two days ago it started locking up hard. Ran memtest 3.3, 1.7, and TestMem 4. TestMem just freezes, memtest failed on moving 8 bit inversions. Letting memtest run eventually causes the system to restart. I pulled memory sticks one by one, and then… >>> More
