    The big MSI MOA 2012 Thread

    in HWBOT Competitions

    Posted

    Here we go....

     

    I first tested MSI mods that msi provided on my own card, with BIOSes that will be on competition, card needed little cold to boot, 1.4v was reading on gpu and in win I needed to start gpuz render test immediately not to get red screen, before starting NVPMM and get in state PO, after that everything works normal, and I can go with voltage over 1.61v ( tested 1,72v just reading ), we did quick run at 1830/1770 on 1.61v and everything went well. Now I switch to competition card and do the same mods, I get 1.4v on reading GPU voltage and card would not boot, tested on air, then on ln2. We started from -10 to -90 and moving to colder temps we get further with booting, at -80 we get win loading but snapped immediately after it, at -90 also, red screen and voltage went to 0.

    We decided to check 100 ohm mod, first we prepared my own card to pretest it ( removed vgpu mods, and get it in previous state before modding on pin4 with resistor), first reading was at 1.09v at -10 and it was low so we moved to 1.25 and booted normally in win, we tested changing voltage and everything works fine.

    After that testing we also get competition card in previous state ( remove gpu mods ) and moded on pin4 ( we solder to the capacitor following the line, not on pin. Same like we did on mine card ). First start reading was like with mine 1.09v and at -10C, voltage was to low so we switch to 1.25v cards started to boot and restart, after that gpu was dead. Mod was working cause we can change voltage and get reading like with my own card, tried to get it back with normal bios after that but no go....

    Competition card was tested on air and it works normal before all this.

     

    Not sure what to think now....

     

    Sorry to hear that but for sure it is not mode related i have test that mod several times to MOA vga and everything was ok. Are you sure that is Gpu and not memory?
