    I'd like some guidance on a RAM upgrade!

    geebh

      Hi. My PC system is:

      AMD phenom II x6 1055T 2800MHz cpu, overclocked to 3300MHz

      mobo Asus M4A87TD/USB3

      2 2Gb Corsair CMX4GX3M2A1600C9 sticks

      XFX Radeon HD 7950 DD Black

      Seagate 1Tb HDD

      Windows 7 64bit SP 1

       

      I want to add to or change the RAM to at least 8Gb (I think that's the maximum allowable for this mobo). Can anyone recommend the best additions/substitutions for the DIMMS, please?

          You would get a better response by asking Asus, here is some info from there site.

           

          M4A87TD/USB3 | Motherboards | ASUS Global

          4 x DIMM, Max. 16GB, DDR3 2000(O.C.)/1600/1333/1066 Hz ECC, Non-ECC, Un-buffered Memory

          Dual Channel Memory Architecture

          * Refer to www.asus.com or user manual for the Memory QVL (Qualified Vendors Lists).

          * Due to OS limitation, when installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Install a 64-bit Windows® OS when you want to install 4GB or more memory on the motherboard.

          * Due to CPU spec., AMD 100 and 200 series CPUs support up to DDR3 1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz.

          * DDR3 Memory Ultra Low Voltage support

            Either two more  CORSAIR CMX4GX3M2A1600C9(XMP) 4GB(2 x 2GB sticks.

            Or four  new CMX8GX3M4A1600C9(XMP) 8GB(4 x 2GB) new sticks would yield

            better overall performance. These specs were taken from Asus M4A87TD/USB3, M4A87TD Memory Qualified Vendors List (QVL).

                Thanks to arcticwind and chast58 for replying, but I'd seen the QVL list in the manual. I don't understand well enough what is listed in the QVL tables, you see. In fact, I don't know much at all about RAM, dual channel, CAS settings, etc. e.g. the QVL list states (as chast58 refers to):

                CORSAIR CMX4GX3M2A1600C9(XMP) 4GB(2 x 2GB)

                and

                CORSAIR CMX8GX3M4A1600C9(XMP) 8GB(4 x 2GB).

                Does the first above mean that's the maximum configuration (there isn't an entry in the list for CORSAIR CMX4GX3M2A1600C9(XMP) 8GB(4 x 2GB)), or, like you say, chast58, can I simply add 2 CORSAIR CMX4GX3M2A1600C9(XMP) sticks, or get 4 of the second type? Or, should I just ask ASUS, as you mention?

                Games are now widely wanting 8GB of memory or more, so if you get 2x4GB sticks for 12GB you will be ok for modern titles

                  The Qualified Vendors list  refers to is listed on the Asus website, because information is updated on the website, and contains current statics on RAM random access memory modules sometimes referenced as DIMM's Dual Inline memory modules in technical spec's. Random Access memory is how the computer reads and writes memory from the motherboard sockets. MHZ or megahertz refers to the speed at which the Random Access memory modules perform and how they will be recognized be the motherboard. If the speed is too high the motherboard will not recognize the memory, so the computer will not Post, power on self test to the desktop graphical user interface (gui), 1. Due to CPU spec., AMD 100 and 200 series CPUs support up to DDR3 1066MHz. With ASUS design, this motherboard can support up to DDR3 1333MHz. 2. When overclocking, some AMD CPU models may not support DDR3 1600 or higher frequency DIMMs. To clarify 1 if the CPU central processing unit or motherboard brain is an AMD 100 or 200 series the maximum memory type supported by this motherboard is Dynamic Data Ram 3 (DDR3) at 1066MHz speed. It looks like you currently have 2 2Gb Corsair CMX4GX3M2A1600C9 sticks installed in the motherboard which yields 4Gigabytes of memory at 1600MHz speed. Are these DIMMs DDR3? If you want to upgrade to 8Gb memory you may have to go with 1333Mhz or 1066MHz this motherboard might support 8GB at 1600MHz.
