Xtreme Addict Posted September 24, 2012 Share Posted September 24, 2012 Drweez and I figured out the mod for our LOC. Its just a normal vmod. 1 trimpot and no other mods got us to 2000 so not sure why any other mods are needed for moa. Not sure why they going for laptops lol! We'll post it later today. Can go to 1.9 if you really want. No ovp, no ocp. Just vmod goodness Great I was going to measure resistance and find good value for a VR but I can do something wrong lol Quote Link to comment Share on other sites More sharing options...
T0lsty Posted September 24, 2012 Share Posted September 24, 2012 @ T0lsty : Is pin 4 of the chil 8318 responsible for the feedback? (it says 'vcpu" on the datasheet, not sure if i'm getting the right pin) Thanks, yes , pin 4 is FB . Quote Link to comment Share on other sites More sharing options...

Aristidis Posted September 24, 2012 Share Posted September 24, 2012 Just put an 100 ohm vr from pin4 vcpu to ground and no need for vid mod and no limit for vgpu also. Quote Link to comment Share on other sites More sharing options...
matose Posted September 24, 2012 Share Posted September 24, 2012 Unfortunatelly (from what I understand from MSI) it's mandatory to use their latest VGA BIOS and their mods... Quote Link to comment Share on other sites More sharing options...
Aristidis Posted September 24, 2012 Share Posted September 24, 2012 For VGA bios it's ok but with hard mods are you sure cause my card with vid mod boots into windows with but i get red screen immediately and with low temp. The safest Vgpu for booting is around 1.28 with more than 1.30 i get red screen. Quote Link to comment Share on other sites More sharing options...
matose Posted September 24, 2012 Share Posted September 24, 2012 I will not use VID mod... latest BIOS + 100ohm pot works best for me also Quote Link to comment Share on other sites More sharing options...
Perica_barii Posted September 24, 2012 Share Posted September 24, 2012 My own card can boot with msi mods normal at -20, but competition card cannot ( tried higher, lower temp no way..). So I will join Aristidis and Matose too. Tried pin4 100ohm on my cards and it works great, will switch to competition card and test it there....

Quake Posted September 24, 2012 Share Posted September 24, 2012 Just a quick question. The second card we get on MOA, is it gonna be preflashed or what? Quote Link to comment Share on other sites More sharing options...

LyanXXX Posted September 25, 2012 Share Posted September 25, 2012 People expert from here, please. Can you please tell me if the pin 4 is relative to PR133? And one more question. Can somebody tell me if I have to remove the resistor before solder the trimpot to the ground? I think if the answer is "yes", the steps is: 1- remove PR133 2- solder trimpot 100K (ground to right side of resistor), and card just modded, so I can change voltages by trimpot.

jjjc Posted September 25, 2012 Share Posted September 25, 2012 Hey guys, just to confirm E7737IMS.140 is the board bios we will be using at MOA? Just got my board today for some quick testing and want to make sure everything is in order before I fly out tomorrow night. Quote Link to comment Share on other sites More sharing options...
matose Posted September 25, 2012 Share Posted September 25, 2012 No, E7737IMS.MOA is the BIOS we will be using Quote Link to comment Share on other sites More sharing options...

Perica_barii Posted September 25, 2012 Share Posted September 25, 2012 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.... Quote Link to comment Share on other sites More sharing options...

Thanks to all For VGA use 100 Ohm VR Don't remove anything, PR133 is only needed for vid mod. If you removed PR133 earlier you don't have to solder it back, card also works without it. @ Dusan Sorry to hear I yesterday also tested my cards with vmod. I know that 1.85vgpu is too much And I don't know why but I killed memories on MOA sample or after reaching 1900 MHz they degraded so much that only stock works Edited September 25, 2012 by Xtreme Addict Quote Link to comment Share on other sites More sharing options...

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?
