    Not anymore. Considering that I'm using 333fsb procs with 400fsb RAM that cannot be forced to run at 400fsb I think this is pretty good.

    You need to read the first post in the thread. This is sandra unbuffered not buffered like your showing. If you want buff I can post a 6975MB/s 292Mhz 1:1 shot

    He has his unbuffered results one line below his buffered results.

    Steve

    How do you get unbuffered? Mine will no doubt not be as impressive as most.

    I have a RAM timing question:

    my settings on a p4c800e deluxe are 250 5:4 2-3-3-5-4

    Is it better to have timings match up? Should it be 2-3-3-8-4 or 2-3-3-8-8?

    That's two separate questions...

    This is only my second post and I'm pretty new to overclocking...

    Thanks!

    Default Install DIMMs in matched pairs

    If you have a motherboard that supports Intel Dual Channel Memory, read on:

    Background

    For background information on the Intel Dual Channel Memory Architecture, please see these documents:

    Intel Dual Channel DDR Memory Architecture White Paper
    http://www.kingston.com/newtech/MKF_...Whitepaper.pdf

    Dual Channel DDR400 memory can balance the performance of the Intel Pentium 4 processor with 800MHz front side bus.
    http://www.intel.com/design/chipsets/dual_ddr_sb.pdf


    Personal Experience

    I bought a PC with a single factory-fitted 256MB DIMM.

    I installed a matched pair of PC3200/DDR400 DIMMs - in the correct sockets - and measured the following memory performance improvement:

    Pentium 4, 3.2GHz
    Single DIMM 2947 MBytes / sec
    Dual DIMMs 4664 MBytes / sec
    ( SiSoft SANDRA benchmark )

    The Intel and Kingston documents suggest that this results in a 10-25% improvement in overall system performance.

    Hope that this helps

    Regards

    Default Memory

    does anyone have the best (oc) timings for my (OCZ Reaper HPC Edition Dual Channel 4 GB : 2 x 2 GB Memory - DIMM 240-pin - 1066 MHz ( PC2-8500 )?
    I have not oced them in so long I forgot or lost the timings I used before.
