I've got a very annoying problem with my PC's RAM.
First my system:
OS: Windows 8.1 64bit
CPU:
i7 975 XE
Motherboard:
Asus P6T WS Pro
RAM:
Corsair 6 GB Triple Kit (TR3X6G1333C9) [got two kits, making it 12 GB]
The issue:
I recently decided to upgrade my memory from 6 GB to 12 GB. Been using 6 GB (3x 2GB models) of the aforementioned memory nearly 2 years without a single incident. Never had a blue sceen once and PC never behaved strange before.
TR3X6G1333C9 can be even found in the Qualified Vendor List for my mainboard. It says the mainboard supports six modules of that RAM inserted into both slots as two set of Triple-channel memory configuration. Both the mainboard and the CPU can support a total of up to 24 GB RAM.
So I bought another Triple Kit of the exact same RAM I've been using all along and installed it in the remaining slots of my mainboard.
The problem is: it only recognizes 12 GB after a warm boot. After a cold boot it only shows 10 GB installed.
Again, to be clear: When you boot up the system from a powered-down state the PC will only show that 10GB are installed. It will only show all of the installed 12 GB RAM when you restart the PC via the operating system.
But that's not everything. After further investigation I noticed something mindboggingly crazy: my available disc space also changes depending on cold and warm boot!
I have a SSD with 238 GB total space.
When my PC cold boots (showing 10 GB RAM installed) my SSD shows
36.5 GB out of 238 GB available hard drive space.
When my PC warm boots (showing 12 GB RAM installed) my SSD only shows
34.7 GB out of 238 GB available hard drive space.
Could this be related? Is part of my RAM being used as hard drive space?!
I'm at my wits end, people.
EDIT: Okay, I just installed the new RAM only and the problem persisted. So I removed the modules one by one to see how much RAM showed up and I found out that one module must be faulty. It only gets recognized by the system after multiple restarts. Guess I have to send this back. Fuck me.
