Reducing hardware-reserved RAM

First, I'd like to tell you the components inside my computer, so there will be no confusion later on:

  • Motherboard: MSI 970A-G46 (AMD) with click-BIOS II
    Memory: Crucial Ballistix Sport 8 GB (4x2GB) DDR3, 1600 Mhz
    OS: Windows 8 64-bit
    CPU: AMD FX-6300 hexa-core, OC'd to 4.2 GHz
    Video card: Sapphire Radeon HD 7850, 1 GB RAM

When I constructed my computer, I put 8 GB of RAM inside. For the first 3 weeks, everything functioned normally, and Windows was able to recognize & use all of the 8 GB.
But after that, the available RAM (as in Task Manager) dropped to 4 GB. Task manager said that the other 4 GB is hardware-reserved.
I find it ridiculous that the hardware should need 4 GB of memory to operate. It should be less than 32 MB.
So I tried to go into MS config, and uncheck the "Maximum memory" option under the 'Boot' tab. It was already unchecked.
I also tried adjusting it to 8 GB, but that also did nothing.

So is there any way I can manually lower the hardware-reserved RAM on my system, either from Windows or the BIOS? I don't see any setting in click BIOS II which does that.
I never, ever updated the BIOS or flashed it, or anything like that.
