    Question Memory expansion on M3A770DE

    Hello,

    I have a M3A770DE mainboard in my pc, equipped with a 2 x 2 GB Kingston KVR1333D3N9K2/4G memory kit.
    I'm thinking about buying another 8 GB (kit of 2 x 4 GB). Now my problem is that the QVL for my board is outdated as the modules mentioned there aren't available anymore. I also noticed that Kingston changed their numbering system in the meantime so the modules available now could all be new models or revisions.
    So does anyone know if the following kit will run on my board? http://www.kingston.com/dataSheets/K...9D3P1K2_8G.pdf
    It doesn't have to run at the fast DDR3-1600 CL9 speed as i want to combine it with the existing kit and have it running at DDR3-1333 CL9. I chose double sided modules because i read that there could be a problem when combining single- and double sided modules.

    Thanks in advance

    Mixing two disparate kits most times results in disappointment. Not saying it won't but the odds are against it. YMMV.

    Kingston doesn't even show this board listed in their memory finder. If I were you I'm contact Kingston ask ask of compatibility beforehand.
    #1 - Please, when seeking help, enter the make and model of ALL parts that your system is comprised of in your Signature, or at least the model #'s in your System Specs, then "Save' it.
    ____If you are overclocking, underclocking, or undervolting any parts, informing us of this and their values would prove beneficial in helping you.

    #3 - Please use the eXtreme Outer Vision Power Supply Calculator found HERE to determine if it might be your PSU at issue.

    I was about to send a customer service mail to them when i clicked on the "Discontinued Model Search" link on the Kingston memory search page. It leads you to a similar looking page, but this time the M3A770DE is available.
    The before mentioned kit is not listed as compatible there. Maybe it is also too new for the list. Most of the modules are marked as discontinued there except for this kit here:
    http://www.kingston.com/dataSheets/KHX1600C9D3K2_8G.pdf
    The downside is that it's specified at 1.65 volts instead of 1.5 resulting in increased power consumption and heat production.
    I also found my mainboard with the Crucial memory finder, but I don't know if i can trust those results as there are memory kits with up to DDR3-2133 on it.

    Yea, I wonder if the board being in the "Discontinued' list that that means they no longer update it's compatibility list with new memory PN's as they come available.

    Tough call there if you don't prefer the 1.65v you have now.
