RAM Disappearing

Hello!

Recently my RAM has been disappearing. I have 12GB of RAM, but when I log in, my control panel shows that I have only 4GB or sometimes 8GB of RAM installed. I recently had to change my ASUS Matrix GTX 580 to MSI N580GTX Twin Frozr III. I have a 750W Corsair PSU, could this be the problem? Any help would be appreciated.

  1. try re installing the ram modules
    sometimes thats the prob and run some memory tests
  2. Download and install CPU-Z. Launch the app and click on the Memory tab. What do you see?

    Also, how is your RAM capacity distributed (2x6GB, 2x4GB + 1x4GB, etc.)?

    Hello!

    Everything is blank in CPU-Z Memory section, expect size, it says 8181 bytes. My ram is 6x2GB

    Now it shows the normal 12288 MBytes in CPU-Z and 4GB in Windows System Manager.
  5. I suspect that there are two problems:

    1. Your DRAM settings in your BIOS are on Auto and;
    2. Because of 1, your DIMM voltage is fluctuating, causing instability

    Go into you BIOS and manually configure your RAM to their specified values shown on the sticker affixed to the side of the RAM module. If you don't know how to do this, post a link to your mobo and RAM, or provide the make and model numbers, then I can help you further.

    I have Corsair Corsair HX3X12G1600C9 and Asus Rampage III formula. How do i change these RAM settings in BIOS?
  7. When you turn on your system, you should see an ASUS logo. On this screen you'll see something like 'Press F2 to enter setup'. If you don't, the typical keys to press are F2 or Del.

    Once you get into your BIOS, go to the Extreme Tweaker menu. In this menu, you'll find Ai Overclock Tuner [Auto]. Change this to manual. You'll also see DRAM Frequency [Auto]. Change this to manual.

    If you scroll down, you see where you'll configure your RAM to the following specs:

    DRAM Frequency: 1600 MHz
    DRAM Timing Control: 9-9-9-24 2T (CAS-tRCD-tRP-tRAS) 2T is the Command Rate
    DRAM Bus Voltage: 1.601 is default, you should consider increasing this to 1.65

    On a side note, your RAM is not on the ASUS Qualified Vendor List (QVL), but that's not to say that your RAM is not supported, just that the model you have wasn't tested to work or was tested and was unstable.

    Hello,
    I'm sorry for reviving this age old thread, but I've been extremely busy and not honestly motivated with my computer. I tried to change these settings and it still keeps saying 4GB in Windows, but 12gb in CPU-Z. I think that maybe I should just get an new motherboard?
  9. What does it say in BIOS?

    Where can I see the RAM amount in BIOS? I'm sorry for such beginner question, but I haven't been eager to learn about these for some time.
  11. I'd try running each stick individually under Memtest (maybe about 4 passes), if any test bad that may be the problem, if not sounds like something is starting to fail - but suggest memtest first to eith nail down a stick as bad or eliminate the DRAM as the problem
  12. If you tap F2 when computer starts, you enter BIOS and it should be under advanced mode on main page.

    I checked and nothing came up there, odd.
  14. Go into your Resource Monitor and click Memory tab , what does the memory graph say?

  16. There are several places to find memory in BIOS. Look under tools as well. Have to try to install one stick at a time?

    That's one thing I haven't done yet, but I guess I have to do it. My CPU fan blocks some of them and is literally an pain in the ass to install.
  18. I tried to install one by one and it's no use. CPU-Z recognizes them, in their slots, but Windows and other programs still keep saying 4GB.
  19. I'm thinking of upgrading anyways. Would MSI X79A-GD65 (8D) + Kingston 16 GB, 2133 MHz DDR3 sound bad.

    Specs:
    GTX 580
    750w PSU
    i7 950
  20. For an X79 mobo would need a new CPU, that's socket 2011, while the 950 is socket 1366/X58 chipset

    Oh damn it. I thought that 2011 is just a never version, but fits also 1366 socket CPU's. 1366 is discontinued so I have to also get an new CPU :??:
  22. Ain't it a wonderful world? (sarcasm) It can get very confusing, trust me ;) wanted to jump in before someone told you to go for it, many 'experts' I've seen here would have.

    Thank you for the help! Guess I have to use even more money now on the project... :fou:
