I downloaded the Manual for your MB, But scanning it quickly I couldn't find anything about Memory remapping in the Bios section.

Here is a link to get this manual

Memory Remap is located in BIOS/Advanced/Chipset/Northbridge Chipset Configuration in most Asus MBs

If the BIOS only shows 8 then you likely have dead or loose memory. That is, of course, assuming your board supports over 8 GB of memory. Power off the system, and reseat each memory stick to eliminate that as an issue.

Check the fine print in your manual. Some motherboards will only support the maximum amount of RAM at a certain frequency. You might have to under clock your RAM to be able to use all of it.

I have an Asus board and encountered a similar problem. Turned out the ram modules were the same model but the P/N's were slightly different. Matched the P/N's and the problem went away.

And what does XMS mean?
XMS = eXtended Memory Specification

In short, it is a memory specification you set in the BIOS when using high-end RAM.

Exactly. That's what I was getting at with the XMS comment.

Definitely worth a look.

Are your six sticks all matched? Try using three at a time in the appropriate slots for triple-channel use and see if you have a dud.

A quick look around the ASUS site also shows that it could also be a bent pin in the CPU socket.

Thanks for the anwsers.
I dont thing that the sticks are bad because CPUZ recognises all six slots with all six sticks. And besides, this problem is new... just a couple of days ago all 12 GB ram were showing in windows and in Bios...

The only thing that might make sense is the bent CPU sockel pin, because some days ago I installed a new cpu cooler and I removed the CPU to remove all of the Thermal compund from the cooler before. So im guessing its possible that I bent a CPU sockel pin during that process. I think it is worth a look. And if thats the case, is there a way to bend it back?

I dont undestand anything about underclocking or anything related to that topic...

all the sticks are the same model but what does P/N mean, and were do I find that information?
