Memtest result interpretation

[Ludovick]

Hello, first of — thanks for the incredible and free test utility, this is what I had to do to figure out the issue with my new hardware.

However, I'm not clearly sure, on the 4 errors I got by 4 passes of memtest86, they all look like this (only address different):
Test: 3 Adr: A870CB4C Expected: FFFFFFFF Actual: FFFDFFFF CPU: 0



Is it RAM or CPU producing error?

Thanks in advance, have to go to service center tomorrow.

RAM fails more often than the CPU. CPU faults also tend to have a larger impact on many more addresses.

So assume it is the RAM at fault initially. Swap the RAM (or remove half of it) and retest.

Hello David, thanks for answering, would transfer the new bought box to service today.
Been actually receiving tons of errors (memory_management, kernel_security_check_failure, 0x000000D1 etc.), I got a list of at home. The box was restarting spontaneously on some files copy from outer hdd, none of the big software was finished (checksum dll error interruption).
Since I'm not a hardware enthusiast it's just a one big pain.
Hopefully they would just swap the RAM for me and it would help.

Random errors like this are a typical symptoms of RAM faults.
