    I see that your total memory showed by the BIOS is 8 GB of RAM.
    If your motherboard does support 12 GB of RAM memory then one of your RAM sticks is bad and needs to be replaced.

    BIOS limitations, I remember i had an old HP that only allowed 46 MB of memory...

    just tried finding the bad ram, when i took one out and went back into the bios it said i only had 4gb switched around the ram to find the bad one, same result for each one. when there are two in it only sees one if there are three in it only sees two. im wondering if i should try different ram.

    It was an old Pentium 66 overclocked to 133 MHz (66 MHz Originally) And standard 16 MB ram but it was only upgradable to 46 MB...

    I can't believe nobody went on newegg and read the reviews on this board, i read the reviews,like 50 people received dead boards,20-30 people had sata III ports or pci-x slots stop working, 10-20 people had memory issues where the board would only read half there memory, and alot of boards lasted less than a year.

    I would buy a new board,but not the same one,lol, o and read the reviews first.

    The only way I can think of that you'd be able to use 12GB is to run a whole lot of programs at once, preferably programs with memory leaks.

    You could try loading up like 20 games at once and a whole bunch of other software and encode a couple of videos at the same time and you should get somewhere close to using 12GB ram.

    Honestly though I think programs with memory leaks, such as the older version of Firefox are your best bet, other than that I have no idea how you'd manage to use up 12GB of ram. I doubt I could even if I tried.

    Put one stick in at a time and try to boot. If it boots every time and recognizes all the RAM, you have a bad slot.

    If all your RAM slots do recognize the RAM,but cannot use more than 8 GB then your motherboard is not working properly and your only way to have 12 GB of RAM memory is to replace that motherboard with the one that actually works properly.

    WOW, I'm having the same issue, the same EXACT issue. I never realized it until I was looking on Nvidia GE Force Experience under >my rig, and it stated I had only 7.99 Gb useable even tho my installed Memory was 12 Gb, and yes indeed I do have the X58!

    I now regularly check My Computer>Properties and it seems after I play games with alleged memory leaks (like the Bioware games) I have this missing RAM. If I go into the BIOS and load optimized defaults and then F10 to save, I get ALL my RAM back. But I shouldnt have to do this...

    I'm wondering if like killerchef04 mentioned that the X58 is defective, but then the Bioware games have notorious Memory leaks. Wish I knew 100% what the cause was, bc I really like the mobo and was gonna get an Asus Rampage III Black x58 and a Core i7 990x CPU for my upgrade, but now I don't know.

    Five years later :p

    I'd test slot per slot with each stick.

    The last time I had usable ram less than installed was due to ram failure.

    I've had it due to incorrect timings and speeds being automatically set by my BIOS. Manually set and fixed.

    Oh!
    Bc like I wrote, when I load optimized defaultsand save with F10, I have the full 12 Gb! But after I play certain games, or maybe just from using Internet Explorer or just a regular restart it goes back to 7.99 useable. Maybe like u said I 'll have to manually set it to 12 Gb? Could u pls provide instructions on how to manually set?
    Thx guys for helping me with this old as F#%K topic! lol
