I have seen this problem before:

1) Just because you can install 24GB of RAM in the motherboard does not mean it can use it.

2) Even if the manufacture of the MB says it will use 24GB of RAM that many only be true if you have the latest BIOS and the correct revision of the MB. You may have revision B and you have to have revision D before you have access to 24GB of RAM. Your owner’s manual and the web site many NOT tell you this and the only way to find out is to call the manufacture’s tech support.

3) Miss match RAM. I have had a MB report that it has 24GB of RAM and everything looks good in BIOS only to have less in the OS. Swapping RAM for all matched fixed the problem.

Just a few notes from the field.

Have you tried running a Ram Test Utility to see if it also only sees 16 GB ???????
So you have six 4 GB sticks ????? and only four can be seen by the OS ???

GO to Start and type in resmon and it will show how your ram is being used. Windows 7 uses ram different. Just let Windows 7 handle it. Some is in reserve,standby, ect. No tweaking is recommended by me.

How much RAM is being reported by the BIOS when you boot up? This is usually reported in MB, so it should say 24576MB if all your RAM is recognised.

Less than 4.0 GB RAM usable?
It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...

RAM 6.0 GB (1.95 GB Usable) WTF?!
What's this all about? Last time I checked system properties it said 5.5 GB usable. Now, today I noticed that my sidebar said that my memory is 40% in use and there's only 1.5 GB available. What's going on here? I was thinking it could be my video card taking the memory, but I didn't change any...
