    Default GA-EP45-UD3R memory issues

    hi guys here is my issue. I have a GA-EP45-UD3R motherboard which if i use 4x1gb of 800mhz ram running at 1.8v. I can run it all day long no issues. Now i have 4x1gb of KHX8500D2K2 1066mhz ram which i can only run 1 stick.

    I have tried changing the voltage from auto to 2.2 and once again i can only run 1 stick. Any ideas???

    Can you run each stick individually, or only one of the sticks works? You can't run just 2 sticks?

    You should probably try 2.1v, and setting the timings to Auto if they are not already. Then maybe bump up the MCH voltage a couple of notches. If that won't work, try running Memtest 86+ on each stick individually.

    I would put performance enhance to satndard, use a strap with a C at the end and bump your MCH voltage to 1.2v.

    i tried those settings and i still can only run with 1 stick. im at a loss, im thinking this board cannot handle 2.2v very well. I can load 4 sticks of 1.8v 800mhz and run it all day long. any one else with any ideas?

    This needs to be set to "standard", not "turbo."

    This are what the latest settings work with 1 stick. If i add a second it just turns on and then off and i have to go back to one stick to get back into the BIOS.

    Welcome to my 1 month nightmare fcktheworld.

    powergiga, can you post your complete bios please. we have almost identical set-ups and I can't get 2 sticks to run. i got the black pi 6400s myself as well, so i want to give them a try with your settings.
    edit: you are running a dual core and not quad.




    I swear this board has some kind of memory controller issue with more than 2 sticks of ram and a quad core.
