Hi everyone,

Do one knows any tool under linux to determine which slot is buggy, without having to test each slot separately ?

Christophe.

Depends on whether your memory is interleaved or not. If it is, you'll probably have to crack the case and remove one. Test both independently. It could also be a timing issue on the interleave. I have a system where both DIMMs check OK, but won't work together at full speed.

If you aren't using interleaving, then it should be a matter of calculating whether the memory addresses that fail are in the top or bottom half of the test range.
