How to identified which DRAM IC defective

[DenT]

Hi,
We recently purchased MemTest86 Pro v11.7 to perform memory testing. Could you please advise on how to identify which DRAM device or DIMM is defective when memory errors are detected during the test?

Theres only one DIMM in your screenshot?

The Chip decode level is only available in site license.

Generally home users & small business users don't care which specific chip is bad on a module, as they can't be repaired or replaced, except at specialist facilities.
