    Unhappy RAM problems with GA-EP45-DS3 & E5200 & A-DATA DDR2-800+

    Hi all. I've mounted my new system a few days ago and I keep having memory problems (I think) with it running at stock speeds.

    I bought these MB, CPU and RAM to update my system:
    Gigabyte GA-EP45-DS3
    Intel Dual Core E5200
    A-DATA Vitesta Extreme Edition DDR2-800+ (2x1GB, 4-4-4-12, 2.0-2.1V)

    At first the system didn't even POST (continuous reboots after a few seconds), but I left only one stick of RAM in slot 1, and it started to work, and I was able to install Windows.
    Then I installed the second stick and I started to have hangs, BSODs and reboots, so I decided to check the RAM with Memtest86+. I got errors during test 5 at the end of the memory range (1950MB+), so I checked with one stick at a time at stock timings and voltages, no errors.
    I then tried raising RAM voltage, MCH voltage, with no luck, and only when I started to change timings I got an improvement. In fact, when I set the main timings at 4-4-6-12 (again, stock speeds and voltages), I don't get any errors in Memtest86+ or Prime95, although my tests haven't been very long yet.

    With these changes I thought I had at least an stable system, but it wasn't the case, I keep getting BSODs in Windows very often (the words MEMORY_MANAGEMENT appear as part of the information). Worse than that, I decided to make some tests with only one stick of RAM, and the BSODs haven't dissapeared.

    These are my current settings, with only one stick of RAM:

    I have tried increasing the voltages, timings, but no luck. I don't know what else to try, and I'm considering buying different RAM (Geil or Crucial) or a new and more powerful PSU, as I don't have any of these available to test.

    Any help will be really appreciated.
    Thanks.

    See if this helps, if not you may have some funky or incompatible ram? Can you test it in another system to be sure? >>>

    This is just 2x1GB right?

    Yes, it is 2x1GB, though right now only 1GB, since I was just testing with one stick to see if I can get it to be stable.
    Anyway, thanks for the settings, I'll try them and post the results.

    Ya, I think maybe Auto for Static Tread or Memory Multi, or Driving strength was what was giving you issues

    Good luck, I will see ya tonight I am about 4-5 pages behind

    I've tried those changes.
    Sorry about ICH Core setting, I had copied the settings to post mines, but didn't delete that. It doesn't appear in my BIOS.
    I've changed the rest, though, but it made the system even more unstable. Windows rebooted before I could open Chrome.

    I tried changing tRFC from 42 to 52, as that is the value MemSet gives from my memory SPD, but no change. Then I tried to restore my old settings, but the problem persisted.
    So what I have done now is clearing the CMOS and loading optimized defaults, setting manually only the RAM voltage to 2.1. Are the settings you posted the safest I can use for 2x1GB? I only want to have a rock solid system, and afterwards I can try to improve the performance little by little.

    Currently it's working fine, at least I can write my results
    I haven't done any stability tests yet, and I'm with only 1GB, but at least Windows hasn't rebooted yet.

    I will keep you informed with my findings.
    Thanks for your help and your patience.

    Still having problems
    I'm going to try to reinstall Windows and/or use a Linux Live CD to see if it's better, just in case there's something wrong with my current Windows installation.
    Besides, there's a lot of snow and I can't go to buy new memory or a PSU

    I finally could go to buy a new PSU and RAM.
    I bought a Corsair VX450 and GeIL memory, model GX22GB6400UDC, that's 2x1GB DDR2-800, 4-4-4-12, 2.0V.

    With optimized defaults, and only changing RAM voltage (2.0) in BIOS, I didn't have any errors in Memtest86+ 2.11 (3 hours testing, more or less). Given the problems I had with the A-DATA memory, I thought that was it, but once I started Windows the problems reappeared.

    I have tried the settings you suggested with this RAM too, Lsdmeasap, but it doesn't change anything.
    I have also tried to reinstall Windows, just in case, but the installer just reboots when it's "installing devices".

    I have used one or two sticks of memory, no change.

    Currently I'm using a Linux Live USB, and so far I have been using it without any apparent problems a lot longer than I was able to in Windows. I don't know if this makes any sense to anyone, as I don't know what to blame, motherboard, hard disk, software...

    I guess I'll try to get another hard disk to test, and if that also goes wrong i'll have to return the motherboard, though I don't know if I will be able to convince them it's broken.

    I'll be testing different things at least until monday. Meanwhile, if anyone has anything to suggest, I'll be happy to try it.

    I'll keep you informed, whatever the result.

    Well, I've just had a couple of crashes in different web browsers in Linux, without doing anything special, so I guess it means it's not a hard disk or Windows problem.
    It seems Linux just handles the problems better and it doesn't crash the whole system. I could even leave Windows completely and go on with Linux, if I didn't need my games
    I think this leaves me with only the motherboard (or it's settings, but I don't know what else to try) as the source of the problems.

    I'm sorry if you are bored with my continuous posts, but I feel frustrated...

    Please give me the full settings you are using now. You are just using 2x1 GeIL mentioned above correct, just checking
