I loaded MemtestX86+ V:4.0 first and it ran 2.5 times and found no errors.
It listed RAM as 400mhz, DDR800, 6-6-6-18 timing
I then loaded MemtestX86 v3.4 and it's currently still on the first pass at 35% (with errors)
Interestingly it listed Ram spec differently than the above program as 365mhz, DDR731, 2.5-7-5-7 timing
This first pass has completed tests 0-7 and found no errors there. It's currently running test 8:
Test8: (Modulo 20, Random pattern)
Testing: 120K - 2048M 3838M
Test 8 is still running as I said and seems to be stuck or running very slowly as it counts individual errors on memory in slot 0.
The report is showing errors per memory slot as:
slot 0: 205,000,000 and counting
slot 1: 2
I assume from this that the memory in slot 0 is bad, how about slot 1 which had 2 errors?
