All RAM not being recognized

Windows is saying

"Installed memory (RAM) : 16GB (14GB usable)"

computer specs

MOBO = MSI X-58 pro-e

RAM = 24GB (6 x 4gb sticks) Gskill RipJaws

CPU = I7 @ 950

Windows 7 Professional 64 bit

HELP PLEASE! Also if you need more specs or info just let me know!

I appreciate the help

 

This is what Crucial/Micron states that your motherboard uses:

Memory:
DDR3 PC3-10600, DDR3 PC3-12800
Memory Type: DDR3 PC3-10600, DDR3 PC3-12800, DDR3 (non-ECC)
Maximum Memory: 24GB
Slots: 6

I know what my MOBO allows, but shouldnt it say 24GB instead of 16?

 

Which Windows version do you have? Some only licence you for 16GB maximum.
Starter: 8GB
Home Basic: 8GB
Home Premium: 16GB
Professional: 192GB
Enterprise: 192GB
Ultimate: 192GB

Check that the installed RAM is on the 'board makers QVL list. There are times when 'compatible' RAM works, until you hit the maximum ...

Check for a BIOS update.

 

They are using Win7 64bit. My guess is either bad RAM module, or incompatible modules installed. Time for the user to download and run Speccy in this case, and post the results.

 

My bad, should have waited until my eyes were fully open this morning

Don't overlook the BIOS check/upgrade, it's a common fix.

 

I've updated the BIOS, I've already been assisted by a friend who knows his shit. He had me do everything, update everything. I'm thinking bad slots

 

Looks like last bios update, along with other driver updates was back in 2011. Very old motherboard.
http://us.msi.com/product/mb/X58-Pro-E.html#/?div=BIOS I am thinking that the mboard is having other issues, which is common after a while, especialy if you do not keep the system cool, or overclock, clean the dust bunnies out on a regular basis.

If the OP would post a picture of the outside of the case the mboard is in, and the inside with the cover is off, maybe we can find a better updated motherboard, that would allow them to be more up to date, if they are willing to go that route.
