    Default Ga-ep45c-ds3

    Hi,

    I'm thinking of buying a GA-EP45C-DS3 for my new system. Are there any issues with this board I should know about? For example how well does it work with 2x 2GB Dimms set to run on 1066Mhz speed ? I'm thinking of using Corsair TWIN2X4096-8500C5D memory, is it a wise choice ? Any help would be appreciated...

    So you think the same incompatibilities could be with a P45 chipset board ?

    Also, the memory brands you suggested are not available in my region :(

    Yeah, I would imagine so.

    Hmm, what brands are available to you? Those will work, but you may or may not have a hard time getting them setup easily

    I can get Kingston, Corsair, Apacer, A-DATA, PQI, Patriot, GOODRAM, KINGMAX, NCP and Supertalent. But I imagine most of them don't make 1066Mhz DDR2 Dimms...

    Well, I would choose Out of those Kingston, A-Data, Pqi, and Patriot. Over here, Patriot is the only one I see that makes 1066 2X2gb sets.

    Or you could get some others on ebay likely shipped to you without issues, ebay has changed some policies that make it safer/easier for ALL sellers to sell to any country

    Hi, I have a GA-EP45C-DS3, and I am having some overclocking issues.
    I've got a e4800 and 2gb corsoir dominator 1066mhz memory (which is definately compatible with the P45), and the only way I can get my processor up to anything respectable is by increasing the core voltage to 1.3, and then slowly increasing the fsb until I get to 4.14 ghz, at which point i change the voltage to 1.41. If I add more voltage earlier the bios will automatically reset. My problem being that when I then boot the computer up after having the computer running prime95 for several hours (or even just a reboot) and the BIOS will reset the settings.
    Does anyone have any idea how I could go about disabling the 'dual bios' feature to allow me to overclock.
    Regards, Matt.

    Also I have a coolermaster 650W PSU so no voltage issues there.

    Sounds like you still have some incorrect settings. Please post your full settings and I will see if anything looks off. No, you cannot disable that, and if you could/did your board would not start since your loading defaults at startup your settings are not fully correct

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours
