Hello, today I installed 2x4GBs DDR3 ram into my computer. my computer has enough power and has a radeon HD 7770. I tested each stick in memtest and in Bios shows I have 8 GB installed. However, when I open up resource monitor in the task manager it shows 1 GB is 'hardware reserved'. On top of that, the OS takes up 1 GB of ram so in reality I only have 5-6GBs available. I asked an expert on another website and they said that my computer was reserving 1 GB for the onboard memory, even though I'm not using it. My Radeon HD 7770 has more than enough ram, 2 GBs to run. Please help.
