    I'm not ready to overclock just yet. Maybe later. Getting dual channel working is my top priority at the moment. I can run 2x2gb in single channel fine; dual channel -- no matter if its slots 1&3 or 2&4 -- always gives me the reboot loop. I tested each module in slot one and they both boot up and run great. I've tried getting help from Mushkin but it doesn't seem to resolve anything. I've tried adjusting the MCH voltage (1.050v, 1.10v to 1.24v) and the DRAM voltage (2.0v to 2.1v) variously but that didn't provide any success.

    Please fill out a template from my signature with your BIOS settings you are now trying that fail and I will advise back

    If you have a good cooler and don't mind overclocking sometimes this is actually easier to stabilize than stock. Just something to think about

    Maybe it's a good idea to clear CMOS after all.
    What are the board rev. and BIOS ver.?

    @lsdmeasap: I'll probably fill out the template tomorrow. Would you honestly consider my zalman 9300at adequate if the core temps are in the high 30's at idle and under load mainly in the mid to high 40's under load?

    @chike: Aside from the battery method, what is the exact jumper I use to clear the CMOS?

    My board's revision is 1.6 and the BIOS is up to date with FB (factory installed).

    FDa is the latest BIOS >>
    http://forums.tweaktown.com/f69/giga...st-bios-28441/

    That could help!

    I think those temps sound fine to me, although I have used 9500 and 9700, is the 9300 smaller than those. If so you could always get better as I thought the 9700 could barely keep up with my 8400

    Jumper you need to use you will find on a old CD or DVD drive on the back of the drive, how to short using this method is outlined here in post #2 >>

    Oh, I wasn't aware of that being the latest til' I did a quick look-up and found that to be the beta. It's safe to run the beta, correct?

    It sounds fine, but I'm a little uneasy about clearing the CMOS without a floppy drive installed (I've considered it obsolete for a while now lol) just in case I get a corrupt bootblock. Is it not likely at all to happen provided that I wait the 20 minutes?

    Yeap it is safe, I only run Beta's myself

    You will be fine, that rarely happens anyway I just had to make note of it for those it may happen to. 20 minutes is often not needed either, again just precautionary statement to make a note of it for those who may need it.

    3-5 minutes will often get it done just fine, quicker if your PSU is switched off and you drain the remaining power from the PSU by pressing and holding the case power button with the PSU Switched off

    But you really do not have to clear the CMOS anyway if you plan to flash, just go into Qlfash and select the BIOS file and disable "Keep DMI Data" then flash away

    Okay, so I ran an iso of memtest and I got 2 passes and no errors and let it run for a little over an hour; the ram was 4gb in single channel in slots 1 & 2.

    2 passes is good, but I do recommend 5-10 or overnight to be sure

    Are you saying the above settings failed? If so I can advise back, if they did and you don't really care and want to overclock let me know what FSB and I will give you a set of suggested settings?

    Default Re: EP45-UD3P reboot loop

    Yeah, the above settings failed. I suppose I could overclock the CPU; I'm a little hesitant though because I don't want to significantly reduce the life my hardware so I can get extra performance out of it. I usually use a PC for about five years and I wouldn't want to squeeze extra performance out of it, and know its going to run a year or two less. I'm not really informed about overclocking for the most part so some enlightenment on the subject would be fantastic lol. Thanks man.

    EDIT: If I must overclock the CPU, something like 3.0Ghz would be fine...something minor. The PC is fast enough as it is coming from a 1.75GB PC 2700 Pentium 4 2.8 lol.
