Memory Problems

I just finished putting together my new computer, an A64 3200+ with MSI K8T-Neo2 mobo.

I installed a 512MB stick of Kingston HyperX memoery, and the BIOS only picks it up as 256MB. CPU-ID picks it up as 512MB.

Replaced that with a stick of Kingston ValueRAM, same problem. Could it be a motherboard problem? Or is it because the RAM isn't listed in the "Approved Vendor List" for the Motherbaord?

Any help or ideas would be great.

For the MSI K8T Neo2, if you are installing a single module, you must install it in: DIMM2 CHA (green)
*Always install in the green slots first.

If you are installing a pair of modules you must install them as follows:
first module: DIMM2 CHA (green)
second module: DIMM4 CHB (purple)
*MSI advises you use identical modules for this setup.

I got that...the problem seems to be with the BIOS recognizing the actual amount of RAM installed...It only shows 256MB, not 512.

Also, Under Control Panel->System, it only shows 256MB insalled.

Whats up with that???

May be a screwy BIOS, check the website for know issues.

I would think it is the motherboard, since it's happening on two different modules.

Sometimes the memory controller cant read the memory module banks correctly. Your 512MB stick has two memory banks on it, each bank consisting of 256MB. If the memory controller has a problem reading one of the memory banks, it will read it as a 256MB module, which seems to be the case here. The MCH (memory controller hub) is on the motherboard.

Seems like your board is very picky about how the modules are arranged. I would double check.. try every slot.

Make sure you have the most up to date BIOS for your motherboard.

If not, perhaps request an RMA, or see if your vendor can provide you with a better suggestion.

That worked....updated from 3.0 to 3.3 BIOS, and the memory works OK now...Although memory wasn't listed as a fix in that release :wink:
