    Windows wont use over half of my memory


    Hello all

    I just ordered and built my new custom PC a few days ago i have 8 gigs of Gskil ram in it and it shows that it can read it but it only is allowing 3.55 to be used. i checkd the MSconfig to make sure the max ram box isn't checked. i have read before that some of your parts will use ram like an on-board sound card or video but the only thing i have on board is the sound. and i dont think it would use over 4 gigs of my ram. is there any other ways to check or fix this problem.

    thanks

    Please provide screenshots from CPU-Z, from the tabs for CPU, Mainboard, Memory, and all the SPD slots.

    Also, can you please provide a screenshot from task manager: Start -> Run -> Taskmgr, then select Performance tab, and push Resource Monitor button. Then select the Memory tab, and take the screenshot of the bottom of the screen where it shows the color-coded and numeric value memory allocations... including "hardware reserved".

    You are absolutely correct... that Task Manager -> Memory picture shows "4.5GB hardware reserved!!!" That's why only 3.5GB is available for Win7.

    We need to get to the bottom of that.

    I wonder, have you tweaked your BIOS for anything other than motherboard defaults?

    I haven't looked closely at your peripheral cards and other hardware, but nothing I can think of would normally need 4.5GB of system memory.

    Well, I'm baffled. That EVGA 01G-P3-1460-KR GeForce GTX 560 video card has its own 1GB memory, so it shouldn't be taking anything from RAM I wouldn't think.
