  • I have 6GB DDR3 installed on mobo, but BIOS and Windows only detect 4GB

    Hi,

    I recently bought the Asus P6X58D-E mobo and Patriot Viper Extreme Performance 6GB DDR3 (quickcode 34290) from Aria, along with several other components for my new build. Since I received the order and assembled all the components together, I have been having this problem with the RAM. Basically I have 6GB (3 modules of 2GB) installed but the BIOS, POST and Windows are all displaying that I only have 4GB installed. CPU-Z shows me as having 6GB installed, but it displays the modules as being installed in different slots to the ones they are actually in. I originally installed the modules in slots A1, B1 and C1 as instructed in the manual for the P6X58D-E. I've since tried swapping around and installing them in different slots, but that hasn't helped. I looked into updating the BIOS, which was mentioned as a possible solution on some Google searches, but the board already has the latest BIOS version installed out of the box. The modules don't appear to be damaged and neither do the slots on the motherboard, and there is no reason why they should be. Is there anything else I can try at this point before I have to RMA it? I'm not sure what else to do, just baffled as to why only 4GB is being detected. Would appreciate any advice

    first thing is if your udsing a 32bit version of windows 4 GB is the max you will get

    if you are using a 64 bit version look for something in the bios called memory remap
    or the likes of and enable it

          It might just be an incompatability between the board and the RAM or a faulty memory controller.

          Socket 1156 and 1366 suffer from this on ASUS boards.

          Thats why after 3 RMA's for clients i mainly buy gigabyte.

            memory remapping for w7? :/

            its VERY rare that there is any 'true' compatibility issues with ANY modern ram and board, mainly because all ram has to perform to a standard. and all current boards and chips support that standard.

            you either have 32bit os, need to enable memory remapping. or have a faulty stick of ram.. or most unlikely. have a faulty dimm

            if there was a faulty stick you would get BSOD every so often, and from your description i think RMA would be pointless.

            the board clearly recognised you have 3 sticks installed.

            personally i think its cos youre on a 32bit OS....

                  just to help out. you can legally download the 64bit version of whatever os you are using and install it using your current licence key.

                      Thanks for trying to help guys. I'm running 64bit Windows 7 Ultimate already. I haven't changed the memory or timings from the defaults. I'll report back on what they are actually set at.
                      Also, I can't find any memory remapping option in the BIOS or even anything with map or remap in it. I'll have another look :/

                        It could be under 64-Bit mode or something.

                        Just look at all your RAM options and post them here, we'll take a look.

                          Have you got any other RAM sticks you can test the motherboard with?

                            I've taken some screenshots of my BIOS and also a couple of the inside of my case. They can be viewed by clicking the links below.
