Re: 256 MB memory missing

Well, now I'm baffled.

Me, too. It's so weird.

Now I tried quite many combinations again. Sorry that one thing I
wrote
in my previous email was wrong. 1GB and 256MB works fine and it
results in 1.25GB.

1GB low density non-ECC + 256MB with-ECC = Will not POST.

So, this works and it is also 1.25 GB.

Let me put what I've tested:

Bank1 + Bank2 = Total
--------
256MB + 512MB = 768MB
512MB + 256MB = 768MB
1GB + 0 = 1GB
1GB + 256MB = 1.25GB
256MB + 1GB = 1.25GB
1GB + 512MB =1.25GB
512MB + 1GB = 1.25 GB

There is also one more point. I flashed my BIOS just in case
and while looking thought the BIOS option I realized that I can
have this quite memory test in the beginning. There I can see
that the problem is not from Windows at all because at the
beginning BIOS determines the values as I wrote here.

OK, I have a theory. Chip select is broken on one of the
slots, such that only one side of one of the slots
is addressable. This may become more apparent, if you

Nope, that can't be the case considering the samples I've
written above.

Next thing I will try is buying the same 1 GB module and
trying next to the other 1 GB module. If it works, it would
be good for the performance anyway because the two
slots will have the same memory modules.

Another option would be buying a better quality 1 GB
module, such as Kingston but would it really matter?

It almost looks like the BIOS has capped the total memory.
I wonder if there is a resource conflict somewhere. There
should be plenty of room for AGP aperture, PCI bus mappings
and the like, so there is no excuse.

I found this thread - a user tried 2x1GB in the board, and
got a slowdown in games. Even though the BIOS screen says
the RAM is running at DDR400.

I found an MSI tested memory document here, and they have tried
1GB modules in the board. There is no record of them trying
combinations of modules, or two of the same modules.

I notice that a few of the modules are ECC in that document,
so they also seemed to try ones with ECC and ones without.

Would you happen to have a PCI video card ? Say, swap out
the AGP video card, and try a PCI one. Other than that,
I don't understand why the total memory is being capped
at 1.25GB.
