Windows XP Pro 64 only shows 9.99GB of 12GB of RAM?

[lz22]

I recently put together a computer and put 6 sticks of 2 GB RAM onto an ASUS board running Windows XP Professional x64 Edition and it only shows 9.99GB of RAM when I right click on My Computer under properties. Should this be occurring?

I would say you have a bad stick of ram. But why would you need 12gb of ram? What do you use your computer for?

what your bios is reporting ?

I believe microsoft put a 10gb RAM limit on windows xp x64, but check what your bios says.

Nope, here is the list of OS's with maximum amount of ram.

An x58 board? It supports as much as the i7 in it does

Well, this has me stumped. Have you checked each stick of RAM individually?

Look in the bios and see if you have a Memory Remap setting, if so enable it and see all 12GB. shows up.

Start->Run->type MSCONFIG->Boot->Advanced Options-> Check that maximum memory isnt checked.

However, being that you seem to be missing the amount of all DIMM's minus one, you may just have a defective stick of memory or one isnt fully inserted into the slot, try removing and reinserting all DIMM's.
