    Arrow EP45-UD3R - Memory will not Post/boot in dual channel config

    I just finished a new pc build, and I am having issues with my mobo (EP45-UD3R) /memory. Full Specs are in the sig...



    On initial install (Bios F4), ram in dual channel config (1&3, 2&4) would not post, emitting short continuous beeps (power error). Removed one of the Dimms, everything posts and boots fine. Add the second Dimm in single channel config (1&2), everything posts and boots fine. Bios/mobo detected timing, but not proper voltage, manually adjusted voltage to 2.1v in bios...same no post/beeps.

    Cleared Cmos, tried dual config, same results.

    Updated Bios to F5, now Dual channel config does not post, no display, but only beeps once and spins all the fans. I have tried Dimms in 1&3 and 2&4, both with like results.


    Any suggestions?

    I just finished running Memtest86+ and the memory passed all tests with no errors.


    Could I have a Bios setting wrong that would cause this? Could it be a problem with the memory controller?

    Test each slot on by one to be sure you dont have a faulty slot

    What Static tRead are you using? Performance enhance set to standard, MCH Voltage added and ram voltage set?

    I am not sure how to test each slot...but I assume that you use only one dimm and try to boot with it in each slot, one at a time?

    Slot #1: boot
    Slot #2: boot

    Slot #3: Blank screen, all fans spin, no beeps
    Slot #4: Blank screen, all fans spin, no beeps

    Slot #1 & #2: boot
    Slot #1 & #3: Blank screen, all fans spin, no beeps
    Slot #2 & #4: Blank screen, all fans spin, no beeps


    Is that how I am supposed to test each slot?



    I tried to keep everything as stock as possible until this Ram issue is fixed.

    Interesting turn of events...

    I pulled some crappy o.e.m. ram (2x2gb & 2x1gb) out of my buddy's pc and threw it on my board...loaded Optimized defaults in the bios and changed nothing...boots right up. Now my Dominator ram passes Memtest with flying colors, so it has to be something I have settings wise that is not correct?

    This is just frustrating!

    Ok 1st thing to try to get this working, set the memory latch(your running 266FSB so use the 266 latch) and divider so your memory Mhz is 800. Also you need to raise the MCH core to 1.24-1.28. Also manually set the PL(performance Level aka Static tRead) to 9 on both channels under advance timings

    Then go from there. Again set this with only 1 stick, then save and exit, then put the other stick in slot 3(so slot 1+3) see if it works? If not, then switch the sticks, so the one that was in slot 1 goes in slot 3 and 3 to slot 1. Try again. If not then you need further tweaking in bios.

    If it does work, then set the mem speed back to 1066 and try, if it doesnt work, swap the sticks and try

    Yes, I was about to say slot 3-4 bad, but glad to see you got somewhere. In your memset screenshot looks like Static tRead is set to 6, that may be too low for your ram

    As said above add some MCH voltage as well, maybe 1.22-1.24 would be good. And put driving strength profiles on 1066

    And use this for your ram setup speeds so you get on the 266/1066 strap for sure as well >>>

    DRAM Performance Control
    Performance Enhance...................: [STANDARD]
    Extreme Memory Profile (X.M.P.).....: Disabled
    (G)MCH Frequency Latch...............: [Auto]
    System Memory Multiplier ..............: 4.00A
    Memory Frequency (Mhz) ..............: 1066

    Thank you both...I will try those settings when I get back home.

    I put my dominator ram in a POS dell pc at work, and they booted just fine with no modifications. Probably running at 800 not 1066...but running dual channel none the less.


    I have memtest going on them now in the dell to see what that turns up.

    I will let you know if the settings you suggested fixed the problem. Could it be that this ram is just not compatible with my board?

    It could be that it is not compatible, but not likely. I have been trying to get them to send me some for testing with no luck.

    I would think the Change or tRD to 7 or 8 at 1066 may help, let us know how your testing goes with changing that
