So I've googled around and tried a lot of stuff to fix this and none of it has worked. Half my RAM is hardware reserved, and I do some image processing of large collections of images, so I need that RAM.
Right now I'm running Windows 7 Home Premium on the following system:
- Motherboard: MSI Z97S SLI Krait Edition
- CPU: Intel Core i7-4790K @ 4.00 GHz
- GPU: Nvidia GeForce GTX 980
- RAM: G.SKILL Ripjaws X Series 32 GB (4 x 8 GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9Q-32GXM
I checked my motherboard's user manual before buying the RAM and it should be compatible.
I've tried going in to advanced boot options under msconfig and looking at maximum memory, and checked on unchecked I have the problem.
I have the latest BIOS updates through MSI.
The BIOS is seeing all 32 GB, as is Resource Monitor and Nvidia's Geforce Experience.
I really don't know what is up. Other posts have had people ask to see screenshots of the resource monitor and the Device Manager's resource by connections window with Memory expanded, so both of those are here:
