    Default GA-EP43-DS3 Overclocking advice

    Hello all,

    I'm pretty new to overclocking and am after some advice on setting up me new kit. I've listed my settings below, I know a lot of them are left on Auto but I just did an optimised reset off the BIOS.

    Thanks :o)

    Motherboard: Gigabyte Model: GA-EP43-DS3 Rev#: 1.0 Bios Version: F8
    CPU: Intel Core2 Duo E6700
    RAM: Kingston HyperX 4GB (2X2GB) DDR2-1066MHz, KHX8500D2K2/4G, http://www.valueram.com/datasheets/KHX8500D2K2_4G.pdf

    Argh, sorry! That would be the one thing I left out of the last post :-S.
    I'd like to hit 3.5GHz.
    Have also just flashed to F9 BIOS

    Not sure if the 9500 will handle this but here is 3.6, if not back off to 3.4 (425 FSB)

    Hi LSD, long time no see :)

    Just to jump in... I notice you wrote multiplier 9x, and should be 8 , right ?

    Also, that board (ep43ds3 wont go 450FSB so easely...even on 425...thats my experience. Maybe its better to stay with original multiplier 10, and then going up with FSB to see how much cpu can take ?

    Just my 2 cents...

    cya

    Thanks!! Long time no see? It is your first post here??? Do you have another name here or do you know me from somewhere else?

    Yes should be 8 CPU Multi. above, sorry!

    You may be right, P43 is kinda limited for FSB and I think I overlooked that. Let me know if you can get 450 FSB Going, if not I will give you some settings to try maybe 9x400 for 3.6 or 9x375 for 3.4 for now using 2.40B Ram multi

    Apologies for what may seem be stupid questions, just testing my understanding...

    The EP43-DS3 says on the box its rated to 1600MHz on the FSB (is that after its been quad pumped? does this apply on a dual core processor?) I know that how far I'll be able to push it is dependant on a whole lot more but I take it that I ought to really just ignore the box?

    I'll be trying those settings tonight when I get in from work :o)

    You guys are a great help, its all very good reading manuals, magazines and 'how-to' guides but there is nothing like being guided this way and being able to ask questions. Thanks!
