Hi,

I ran memtest86+ 4.10 against 4x4GB DDR3-1333 dual channel at stock settings. One error at Test 7/Pass 7 when I looked at screen after 27 hours, failing addr is 0000009ad60 - 0.6MB, does it mean failed RAM is the first pair of 2x2GB sticks?

And how many passes should I run? The error may had occurred after 20 hours...

Thanks.

Swapped slot position of the two pairs, one error in Test3/Pass2, failing address is 0000049ad60 - 4.6MB, err-bits is same, now I'm confused, was expecting failing address > 8GB.

Test all the sticks one at a time to identify the faulty stick.

I guess can't tell the faulty stick from failing address :(

I'm testing each pair of dual channel, no issue so far, but giving one error when testing both pairs, what does this mean? motherboard issue?

Probably an incompatibility between the RAM and motherboard.

I have another two pairs (4x4GB) of identical sticks, running memtest 56 hours without any error.

Now I'm running the suspect pair with the proven good pair, see what happens :sleep:  It's very time consuming.

Using this method, was able to identify the faulty pair :bounce:  but took a while.
