    Hi again

    My psu is an enermax 425 modu 82+ which supports crossfire, so i don't think that's the problem. But even if my psu was the problem the system should work fine with my old Ati X1600 XT (no power supply needed) - even my old Athlon 64 system, which I used before the "upgrade" worked fine with HD3850. Anyway, after 10 days of testing (endless bios settings combinations and no fun) I decided to disassemble the system and sent the mombo back to the store I bought it from for replacement. I will come back letter for further details.

    Thanx for your time and help.

    Just because it says that means nothing, that is just a sales pitch often times Like SLI Capable Memory.

    How many Amps does it say on the side of it for 12V Rail? And what does your card say for system Requirements about the 12V rail?

    Ahh, so you have a new one on the way then?

    My graphics adapter is also a Gigabyte GV-RX385512H (HD3850), but it says nothing about 12v rail requirements.
    Anyway my psu provides 3 12v rails within range between 0-22A.
    Isn't that enough? But my old system I described you before worked fine with the same PSU and GPU.
    And two friends of mine use the same Graphics adapter with 375 psu (heroichi) with no problems at all...

    Ahh ya your PSU Should be ok Maybe, but split rails is often bad especially when you have to consider the rest of your system as well.

    Ahh here is the requirements which you are not reaching >>>

    450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for dual ATI CrossFireX™)
    ATI Radeon™ HD 3800 Series - System Requirements

    I could not find the RAIL requirements anywhere for it, but your already short in Wattage minus the rest of your system

    I got my mombo back (checked) and guess what??? ... my system was unstable once again ... so I sent the psu for service this time (it's only 2 months old) .... I begin to believe that my PSU is damaged ... there is no other explanation ...

    thanx for your time mate

    Well, good luck with things! I am sorry I could not be of more help.

    I think you may be right, it may be PSU Damaged, or like I said PSU is not good enough for your complete system

    You helped a lot ... It was nice cooperating with you ...

    Just for the story ... I changed my PSU with an PCPower Cooling 610Watt and guess what (again) ... I had the same problems ...
    So I decided to run memtest86+ as many times as possible ... (changed slots ect) The first dimm always completed the test and the other one sometimes it did and some times not ... until it could never complete the test .... (finaly it's off).
    Conclussion - my problem was a memory problem (hardware) ... technicians in Greece
    When I get my new dimm back I may need your advice for adjustments if that will be necesary (for the 4GB settings).

    Thanx for your time ... you are doing a grate job ...

    Ahh, well at least you found the issue now! For future reference you should run 5 full passes or so on each stick to be sure it is good not just one.

    Ya, I will be happy to help ya with settings once you get some working ram. Just drop by and let me know

    Thanks for the kind words! I do try as much as I can, Been piling up me me lately though for sure as you can likely see
