    Default Memory Issue with my GA-EP45-UD3P mobo.

    I have G.Skill 1066Mhz PC2-8500 Ram and the GA-EP45-UD3P Gigabyte Motherboard..

    Well the motherboard only read the Ram as 400Mhz, PC2-6400..

    I went into bios but the MHz frequency under the DRAM section only went up to 400Mhz... So i was wondering how I could change this to be 1066MHz?

    Here are the links to both items.. The motherboard says it supports 1066 RAM and the RAM says its 1066MHz Ram..

    Newegg.com - GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard - Intel Motherboards (Mobo)

    Newegg.com - G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Desktop Memory (RAM)

    Any help would greatly be appreciated.

    Also heres a pic:

    Your memory is working at 1066mhz;
    Check out your memset picture
    1.In the top right hand corner of the first panel it shows
    fsb/dram=5:8
    On the next line it shows Memory :ddr2 533.5mhz

    533.5 mhz IS the actual mbrd reading memory speed.
    Since its ddr2 memory 533.5 x 2=1067 mhz

    working backwards 533.5 divided by 8= 66.6 approx
    66.6x5= 333 so your cpu fsb ref speed is 333mhz .
    This means either you have entered /your mothererboard has applied a 3.20 multiplier to your cpu/fsb reference speed to give you a memory speed of 1067 mhz.

    the second memset panel spd doesnt show the speed your memory is running at.
    It shows standard speeds the memory can run at and enhanced performance profile memory speeds.
    In your case the highest jedec standard profile is 400x2=800mhz.




    nb:If you hadnt posted the pic people would just have to guess what you meant.
    Its hard to tell what specific settings are in your bios if you dont use one of the bios sheets from other posts.
    Current Systems:

    Asrock p67 Extreme6.............. Gigabyte EP-45 UD3 ...................... Gigabyte 73 PVM S2
    Intel i5 2500k 4.8ghz................ Intel Q8400 3.8ghz......................... Intel D820 2.8ghz
    Zalman 10x cooler.................... Coolermaster V8............................ HP cooler
    8GB Gskill ripjaw ddr3.............. 4GB Gskill PI ddr2.......................... 4GB samsung ddr2
    60GB ssd/500GB HDD .............. WD 1TB hdd.................................... Seagate 160GB hdd
    GTX 460 1GB x2 SLI ................. Msi 9600GT 512MB(died) ........... Onboard gx
    Win7 64 ,750w psu(ocz)............ Win7 64 ,520w psu,seasonic...... Win XP pro ,400w psu

    ok so basically my memory is working just fine? the PC2-6400 (400MHz) part is what confused me i guess.. I thought that was what the ram was running at..
