Memtest86+ errors

b42 · 2026-05-05 18:50:35

hello,

I am receiving those errors when doing memtest.

I have tried 3 different sets of RAM sticks and every time I get those same errors.

What does that mean in general? Should I be concerned?

if different modules produce the same error the error likely aren't the modules - which, just by logical inclusion, means, that the error is either the ram controller in the cpu or a trace on the motherboard
same as with replacing ram modules to figure out if they are the issue to test whether its the cpu or the board is to replace either of those

okay, will test it on another motherboard (with cpu embedded) and let you know the outcome! Thanks!

this should at least give an insight if the error moves with the modules (which i doubt)
as for cpu vs motherboard: as it's likely hard to get replacements you could try to reseat the cpu - could be a weak connection of one of the pads

I am afraid I will just brick the machine.

Can I do that with hot-air gun? to just heat it and take it off and then reseat it?

If it persists on the current MB, try clocking the RAM down. XMP/DOCP can clock it a bit higher than the modules or controller can handle.

oh - i missed the M on the shot - so, this is a laptop then? important information!

Can I do that with hot-air gun?

Please NO, That IS actually fastest and real way to brick the board
Proper removal requires (as far as I know)
-BGA rework station
-controlled temp profiles
"Experience"
so realistically: don’t attempt that at home unless you already do board-level repair

b42 · 2026-05-06 15:51:59

Yes, it is a laptop.

But as I mentioned, I tried 1600Mhz modules - the same. 1333Mhz modules - exactly the same errors appear.

hmm, have you tested w/ different slots like try just one stick of RAM in Slot A, then move that same stick to Slot B. If the errors only happen in one slot, the motherboard is the culprit, if it happens in both, it’s likely the CPU's integrated memory controller...

and at that point replacement is the solution, also we got to know CPU is soldered; at any way replacing a whole motherboard might not be worthed

Edit:
also, is this actually affecting your workflow in practice?

with an intel 3000 about how many decades old - yes, replacement of the machine should be considered

Have you tried using only the first slot?

b42 · 2026-05-07 05:39:36

Just tried with even different single module than had been used on previous tests, tested both slot 0 and then slot 1 and still got the same errors.

Different board, different RAM stick, same kind of error:

Interestingly enough, previous board, no errors:

What is going on here?

seth · 2026-05-19 14:15:34

So some new DIMM works w/ the system in the OP (?) but not some other (slightly faster CPU)?

Make sure to not overclock anything, no XMP, chose the most conservative RAM timings and clocks and don't overclock the CPU.

That is the thing - I get the errors with both XMP and no XMP.

Using Libreboot.

XMP is out of the question anyway.
