Fail memory tests

Assuming you're seeing a memory failure, record the DIMM number that's failing.  Then reseat (remove and reinstall) both modules.   Test again.  If the same module fails, move it to the other socket.  If it fails there as well, that module is bad - replace it.  If the other module fails in the same socket as the first did, it's the socket that's bad and you'll need a new system board.

I swapped the two DIMMs and reran the diagnostics.  The error remained the same.  

The first error reported is as follows:

Error Code 0123

Msg: Error code 2000-0123

Msg: Memory integrity test failed

Address: 0_5B85C2XC0h, Actual=20000000h, expected=00000000h, Location=DIMM_B

If I let it continue, most other tests fail as well.  This one is consistently the first error, and this is always the error message.

So this means a new system board?  Given that this laptop is 5 years old, I guess it's time for a new one. :-(.

I would run 4 tests.

Dimm 1 in channel 1 w/ channel 2 empty.

DIMM 1 in channel 2 w/ channel 1 empty.

Repeat above using second DIMM.

Can you pass diagnostic test w/ a single DIMM installed in either channel?

What is max size single DIMM module available for your computer?

This laptop has two 1GB DIMM's installed, which is the max.  

I did the suggested tests.

With DIMM 1 in channel 1 and 2, all tests were passed.

With DIMM 2 in channel 1 and 2, the tests failed.

So what does this show?  I can't run with only 1GB of memory.  Do I need to replace the one that fails?  Why do the memory diagnostics give the same error regardless of which slot it is in (when there are two installed)?

Thanks
