Thread: No post & continous reboot, GA-EP45-UD3P V1, Corsair PC2 6400 2x2GB Dual

    Default No post & continous reboot, GA-EP45-UD3P V1, Corsair PC2 6400 2x2GB Dual

    I originally had some OCZ PC2 8500 4x1GB but couldn't get it to work (same issue as below). I read about all the issues and decided to go safe and pick up the Corsair 2x2GB PC2 6400. It worked like a gem for 4 months, not one issue, just loaded optimized settings in the bios.

    Well I haven't used it all summer, boot it up and I got the no post reboot loop again? I'm just baffled. I've tried 1.9v 2.0v 2.1v and all the same result. Today I got it up at 1.9v w/manual timing for about 6 hours of mem test. I decided to add some thermal compound on my CPU because it was getting hot. I did that and go to boot up with the same problem again! The only way I can get this thing up right now is on a single memory chip. If anyone has the correct settings for my pair of memory I would really appreciate it. Also my ram is set at 1.9v but this shows 1.8? CPU is also not running at the speed it should. You guys are the experts. I got pics below. Thanks

    With your computer powered off, turn off the power supply at your PSU and unplug the power cable at the PSU.
    Remove each memory module and re-seat it in the memory slot.
    Reseat your graphics card and any other cards.
    Verify that all wires and cables are fully seated.
    Plug in the power cord, turn the PSU on, and restart your computer.
    Enter your bios and follow the suggestions in this post, making sure that you first load OPTIMIZED bios settings.

    Post your bios settings, add your hardware list to your forum signature and include a link to your memory's specs.

    There is a bit of a problem that many have noticed, at least with UD3 motherboards. On completely switching off at the wall, then ext power on will either be a double boot, ie it will turn on, then straight off then boot ok, or it will go into an infinite loop.

    profJim's suggestions are sound, definitely do them. Afterwards, leave AC off for 1/2 hour and try a cold boot. If it loops, switch the PSU off at the back (keep it on at the mains, switched on if your outlets have switches) and hold the power button in for ~20-30 seconds. If the issue mentioned is what's doing it, when you switch the PSU switch on and hit the power button it will either double boot or turn on right away. I'm guessing it'll turn on right away in your case as you're not overclocking.

    The only way to avoid this issue that I have found is to leave AC power connected at all times. This does use some electricity though. The power button works by being connected to the +5VSB (SB = Standby) rail. This rail needs to be constantly fed from AC to DC via the PSU in readyness for you to hit the on switch. Not exactly eco friendly, but it is part of the mechanism that allows software on/off and is better than the old click in/click out switches of old.
