    Default GIGABYTE GA-EP43-DS3L freezing in BIOS / Memtest

    I am building a new system with the following components:

    GIGABYTE GA-EP43-DS3L
    Intel Core 2 Duo E8400 Wolfdale 3.0GHz
    mushkin 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model 996603
    Thermaltake Purepower W0100RU 500W ATX 12V 2.0 Power Supply
    Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM SATA 3.0Gb/s Hard Drive
    SAMSUNG 22X DVD Burner Black SATA Model SH-S223F

    The motherboard came with BIOS F4, I've flashed it to F8.

    I just don't seem to be able to get it stable, it has been freezing in BIOS screen, freezes within 12-90 seconds into a Memtest, freezes partway into a Vista install.

    I'm currently trying with just one of the memory sticks in and still having issues. I've also tried with two other sets of Corsair memory (setting the correct voltage / timings for the memory each time) and still have the same issues.

    My current BIOS values are:

    MCH Core…………….....1.100V...........: 1.14 for stability

    My BIOS only has the following options for this:

    Auto
    Normal
    1.000V
    1.100V
    1.200V
    1.300V
    1.400V

    Should I just stick with 1.1 for the moment?

    Ahh, well then just add .1 so 1.2 would be fine. but ya you can leave it if you like

    Ok so have the following settings at the moment. have tried these with each stick of ram in individually and both sticks give the same result of only getting through 10-90 seconds of the tests in memtest before the machine locks (as in the wall time stops incrementing and the test doesn't go any further. Interestingly enough the + symbol in the memtest name carries on flashing on and off though).

    The only other piece of the system I didn't mention was the graphics card:

    Starting to think the motherboard might be bad..

    Can you test these sticks on another board? And also, please look in CPU-z to be sure the SPD data matches, and is the correct model you bought. Sometimes they mix things up!

    Does 444-12, and the rest of the timings on auto work ok at all? Have you tried slots 2+4 instead?

    Can you please also test Less then stock MCH voltages, a have seen a few users who had 2x2 which should have needed 1.2 or so say less then stock helped them more then adding. So I think stock may be off from what it says in some boards

    Another thing to check is your cpu temp. Boot into the bios and monitor the cpu temperature for a few minutes. If its overheating then the cpu might be throttling and shutting down to protect itself. The fix would be to reseat the cpu heatsink/fan.

    CPU temp started at 25 C, rose to 33 after 15 minutes, system didn't crash while in the PC Health page on the BIOS

    As soon as I rebooted and ran memtest it locked up instantly on the memtest screen.

    Next I tried lowering the MCH Core from 1.1 v to 1.0.. and that appears to be the fix.. it's been running memtest for over 30 minutes now with no errors.

    So now we have it running stable thanks to your suggestions I assume the next course of action would be to try and tighten up the settings right?

    Ok I spoke to soon.. when I got it working fine above, that was with one stick in. When I put the second stick in and tried memtest it froze about 2 and a half minutes in.

    Going to single stick test the second stick now to see if that is the culprite.

    Single stick test with the second stick seems to be working fine too (though so far it's only been running memtest for 5 minutes, it's always frozen in 2 and half minutes or less in previous tests though).

    EDIT: The second stick passed a full set of memtests, so both sticks are good individually.

    So.. it seems like it doesn't like having both sticks in.

    Once the single stick passes a full set of tests I'm going to try seating both sticks in the 2 & 4 DIMM slots instead of 1 & 3.

    EDIT: Using 2 & 4 DIMM slots instead of 1 & 3 froze after 1 and half minutes in memtest, the same as when using 1 & 3.

    Though I'm also wondering if MCH voltage of 1.0 is fine for one stick, if it needs 1.1 for the two..
