First off, I'll supply specs to assure I don't confuse anyone!
CPU: AMD FX-8350 Vischera (Stock, Use a Cooler Master, Not O/C'd)
Motherboard: Gigabyte Technology Co. Ltd. GA-78LMT-USB3 (Socket M2)
GPU: 4096MB ATI AMD Radeon R9 380 Series (XFX Pine Group)
HDD: 931GB Hitachi HDS721010DLE630 ATA Device (SATA)
RAM: DDR3 1333 8GB Cards (x2)
OS: Windows 10 64 Bit

Recently I had an issue to where my 8gb of ram only had FOUR usable. Now I have purchased two brand new 8GB cards (16 GB) reset my motherboard to default, and windows (64 bit) ONLY TELLS ME I HAVE 12 AND STILL USES A MASSIVE 4GB.

It has to be a setting in Windows I've overlooked. Tried all the unique fixes, no luck.

I will pay if someone can actually get this working

Is this a new build or it was built and this happened?

First thing to try: set your maximum RAM to "nothing." Go to Start -> Run -> Without the quotations, type "msconfig" -> Click the "boot" tab -> Advanced Options -> Make sure the "Maximum Memory" Check box is empty (meaning no check mark). Confirm and restart your computer.

As I asked though, is this a new build or did this just happen one day?

If you tried everything else and its new RAM, then you very likely bent a pin on your CPU. You need to remove it and bend it back VERY GENTLY.

I had a similar problem on a build I did for a friend. Pull out the CPU, are any of the PINS bent? If so, can you make them straight without <mod edit> them up? Second, pull out all of the RAM sticks, put one in at a time, does it show the correct amount? Do this for all sticks. Determine if one of the sticks is defective. After re-seating the CPU, and determining if one of the sticks is bad, it may be an issue with the CPU.

Just happened out of the blue. I've had this build for awhile and upgraded parts (CPU, PSU, GPU) and noticed as I was upgrading and looking at system windows only had half of memory available

It was weird installing my CPU. I will reseat it now and get back to you. One thing, my cooler goes over my first RAM slot, so I use the 2nd and 4th slots for my pair. Any impact this would have?

Check the manual for your motherboard, this could be an issue.

I would say bent CPU pin is definitely your problem. Its common with this CPU

Even better, a pin broke off during installation. RIP $250 investment

Any possible way this can be fixed without buying a new one?

Bummer man, sorry to hear that. You could try and RMA it and say it went bent when you received it but that will most likely not happen.

Be sure to mark the best answer!
