For The MOA Class B Participants: MSI Geforce GTX 750 (Ti) GAMING Hard Mod Guide

In the MSI MOA Class B Qualifier, overclockers have to use the GTX 750 graphics card to compete for 3 tickets to the MOA Grand Final later this year. For the participants MSI made a nice hard mod guide. The guide can help overclockers overcome voltage limitation and disable OCP.

Enjoy!

Awesome MSI!

bios :D? or no need

Australia bob(nz) says:

Nice - thanks MSI!!!

Indonesia Lucky_n00b says:

It was nice of them to provide the mod, since the datasheet for the uP1608 isn't available(under NDA I guess), and there's no software control that can increase voltages (the uP1608 have no I2C interface IIRC). The power offset should be good start for those who want to learn hard-modding and aren't willing to epower their card yet ;)

South Africa DrWeez says:

interesting, the mod I tested was almost the same but not really :D but it works.

Switzerland splmann says:

Is this only for the Gaming Card ? Or also for the reference Card ?

CL3P20 says:

should be only for gaming 750 - which is based on PCB from Ti series and uses uP1608 for GPUv

*AB - works for voltage control on this model as well

@ Vivi - got my BIOS issue fixed**

**also - GPU needs 2x epower.. if you planning on using one..your gonna have a bad time.

Good point CL3P20.

@ Vivi - the card locks system when trying to copy/read BIOS .. :( ..so far, I have no work around

**also - GPU needs 2x epower.. if you planning on using one..your gonna have a bad time.


I don't have the skills to know how to use an epower, but... are you telling me that this tiny card is too much for a single one:D:D

CL3P20 says:

yes.. too bunny. :)

*either 1x epower for vmem or must run 2x, as removing GPUv = 0.01v vmem (havent tried direct feed yet to see if I can 'trick' pgood)

vmods work just fine though.. GPU sips through PCI-E anyhow ;)

edit: ** mod guide doesnt cover PLLv ;)

so for moa i can use 750ti????? bahhh......

no

South Africa DrWeez says:

zzolio said: for a valid score, no. for invalid score, yes

fixed it for you :D

Ok...I will have to look for a e-power board and forget the option of re-sell the GPU after August 31th

BINGO ;)

End is 15th :p

2D goes until 15th, 3D goes until 23th and 31th :D :D :D

Guys i got a gamer 750ti card and followed the mod.
i just did it with pencil since its the same thing and wanted to ease into voltage.
Got the ocp to 2.5k and the nvvdd spot to 4.8k I also have the power limit up in bios(1.23v) but all it did was to get my mem voltage up 80mv? (1.57v -1.64v) also have a 6 pin installed
What i do wrong lol. i should do the ram ocp unlock to maybe since i did not
I know you guys have this BIG contest to do this for,me i am doing it just for fun any help like a bios would be really cool

CL3P20 says:

have to edit your BIOS.. so many rev's of this card.. lots of different mem and PCB *use kepler bios editor to DL/mod for increase in power limit of GPU

United States cowgut says:

ok i think i did that but will go higher
I have four full phase and skhynix on the card.
Have a bios i made yesterday that gives me 1.29v 2d and 3d and what i thought 135w but will try for more.
I have to the mem ocp mod its the only thing i did not do
thanks

CL3P20 says:

may not need mem ocp.. mine wasnt liking too much additional voltage.. and IC's ran out of speed before OCP could be hit. *hope you have better mems ! **You got lucky with full 4x phase !!
