Alright, I finally figured out the problem. I was using a corrupt RAM stick, with each new ram I got. Yep, a series of unfortunate luck. When I went to buy new ram, one stick was busted, when I ret... Go to the full post »

Thanks for the info.
A possible cause of your issue is having mixed speed RAM, it is also mixed in the wrong DIMM channels. See your MB manual page #15.
Slot #1 and #2 show CMZ8GX3M2A1600C9 > http://www.corsair.c...mz8gx3m2a1600c9
Slot #3 and #4 show CML8GX3M2A1866C9 > http://www.corsair.c...mz8gx3m2a1866c9
The RAM is running in single channel mode instead of Duel channel mode and only the stick in slot #1 is available for use.
You can mix RAM of different speeds, but the timing must match. Look at the RAM listed in SPECCY, the only highest spped with matching timing is,
JEDEC #3 Frequency: 666.7 MHz CAS# Latency: 9.0 RAS# To CAS#: 9 RAS# Precharge: 9 tRAS: 24
We need first to set the BIOS to defaults.
Turn off the PSU.
Remove all the RAM.
Use the Clear CMOS Jumper, page #28 MB user manual. this will reset the system configuration.
Install two sticks of RAM, the PC3-12800 (1600MHz) in slot #1 and slot #3
Check that the clear CMOS jumper is back to Keep Data.
Turn on the PSU, power up.
How much memory is now available?

Hey iammy, I took your advice, and I ended up getting two new 8g of ram (16 total)
This time they're the same stick/brand. Also compatible with my board.
UNFORTUNATELY... It's now running at 16 gig with 7.95 GB available.

That is disappointing.
Did you Clear CMOS?
Please run Speccy again and post the new URL.

Alright, I finally figured out the problem. I was using a corrupt RAM stick, with each new ram I got. Yep, a series of unfortunate luck. When I went to buy new ram, one stick was busted, when I returned it, and bought another, it came with yet another broken/non functioning stick. It took a lot of shopping and returning and the help of a pc tech to solve this. :\
Thanks for the help and suggestions guys! Wouldn't have gotten here otherwise.

Thanks for the update.
That's very unusual and bad luck to get DOA RAM like that. Good news you got it sorted, was going to get you to run Memtest86+ as the next step.
You are very welcome
