    Hi all

    Following on from this thread:-

    http://forums.overclockers.co.uk/showthread.php?t=18060775

    Task Manager says I only have 3Gb. Yet Windows System Settings says 4Gb and also CPU-Z says 4Gb.

    However I noticed my \MAXMEM setting for Boot is also limited to 3Gb.

    :confused:

    I've checked in the BIOS (DFI Motherboard) for a Memory Remapping option but do not have one. The only thing I can see that is not DRAM timings is a Memory Hole 15M-16M option. Is this it?

    Thanks all!

    Maximum Memory in Msconfig hasn't been enabled has it?

    Hi

    Yeah I have MaxMem set to 3328, it won't let me go higher. i.e. I can set 4096 which I thought I'd be able to. Is this what is causing the problem?

    Everywhere I've looked shows the Memory Remap feature to be only on Asus boards. :(

    Well I disabled that, and rebooted. Seems to have sorted it! :D :D :D

    Task Manager now reports 4093Mb for Total.

    I had no idea that option was to "limit" the amount of RAM. I thought it helped when the PC was booting?!
