In short, the issue with my PC is that inside of Resource Monitor the hardware reserved for the RAM is half when 16GB is installed. After testing RAM and finding the PC wouldn't boot if RAM sticks were in either or both of the 2 slots furthest from the CPU (without anything in the other two) I thought it was a MOBO issue and brought a new one. However, the issue persisted.
However, no matter what Windows says, the bios always recognises all RAM installed at correct frequency and voltage. If there is RAM in slots 2 and/or 4, the bios will recognise any ram in slots 1 and 3.
For reference, the ram slots are labelled on the motherboard as:
[CPU Socket] 4 2 3 1
We've tried
- Unchecked maximum memory
- All RAM sticks have been tested and do work
- Cleared CMOS and updating BIOS
- Bought new MOBO and RAM
- Ran windows memory test and it found no issues
- Checked all RAM is running at the correct speed
- Checked CPU for bent pin and socket for any debris and found nothing
- Reinstalled Windows
Other issues found
- XMP works sometimes, seems to be no correlation with RAM sticks
- One set of original RAM wouldn't rank in dual channel in CPU-Z
- All RAM is the same model but has different version numbers
After scouring the internet for a possible solution, I have run out of ideas so any help would be greatly appreciated.
