I recently replaced my motherboard with a dual channel motherboard with a RAM limit of 32 GBs

The motherboard is a Gigabyte GA-970A-DS3P Ultra Durable

CPU: AMD FX(TM)-8350 Eight-Core Processor (4018.6 MHz)

Installed Memory: 24GB (16GB usable)

OS Version: Microsoft Windows 10 64-bit (Build 17134)
Graphics Card Vendor: NVIDIA Corporation
Graphics Card: GeForce GTX 1060 6GB/PCIe/SSE2
Windows Graphics Driver Version: 23.21.0013.8813



Any ideas on how to fix this?

is your copy of windows the "Home" edition? I don't know about win 10, but in windows 7, the home edition was limited to recognizing 16 gb - never understood that limitation but i had to buy a new copy of win 7 Pro to be able to use my full 32 gb

There are 4 sticks total 8 + 8 and 4 + 4 they are paired by the color-coded slots. IE the 2 8s are in blue slots while the 2 4s are in the black slots.

According to the book the Blue slots are for channel A and the black slots are for channel B.

I have tried MSconfig as well as deleting all of my pagefiles from the performance settings.

"Exactly" meant make/model as well.

Often, mixing RAM sticks does not work well. This is why they are sold in specific sets.
8+8 and 4+4 was not sold as a set.

And that is why. Mixing brand and speed.
Each set works fine on its own, but not all 4 together, correct?

Sadly, that is often the case.

At some point, Windows kicked it down to 12GB which made me think it was like only accessing 2 sticks at a time.

Okay so I bought 2 more Gskill sticks DDR3-1866 8GB each and I have a similar issue 24 usable of 32 GB I tested each stick on it's own and the computer booted fine.
