Hello all,

I just installed the following RAM:
G.SKILL Ripjaws X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C10Q-32GXL
On my MOBO: ASUS M5A97 R2.0.
with CPU: AMD Phenom II X6 1090T

The issue is that Task Manager only recognizes 16G instead of 32G.

CPUZ shows 32, as well as speccy, and Asus System Info...

BUT TASK MANAGER...(shows 16 only)

Can anyone help me with this? I really need those 32 Gigs.

Also, how do I tweak BIOS' settings so that I maximize the RAM's performance (without OC)?


Any help would be greatly appreciated.

PS:
MOBO's specs in regards to RAM:

4 x DIMM, Max. 32GB, DDR3 2133(O.C.)/1866*/1600/1333/1066 MHz ECC, Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture
** Refer to www.asus.com for the Memory QVL (Qualified Vendors Lists).
* Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Install a 64-bit Windows® OS when you want to install 4GB or more memory on the motherboard.
* Due to CPU spec., AMD 100 series CPUs support up to DDR3 1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.
