Thanks. I am mainly doing this for educational purposes, so I am not very concerned about the AMD miners.
Not following you...what other .dll do I need?

--gpu-platform #number  (you need to run sg/cg with a flag which will dump the mapping of the card... don't remember which param though

put core +106 mem +366
On the bottom of the utility you should see the core clock and mem clock.

I have been using the card reviews at TechPowerUp.com for getting a good baseline on what the card can be OC'd up to.

http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_750_Ti/28.html (just find the card you have)

I am not exactly sure how they come to their settings, but they have put me right in the ballpark for both of the cards I have right now.

Their reviews are extensive, and the overclock info page has the GPU-Z screenshot of their overclock settings.

I have found that everyone using the +100/+500 terms varies so much based on the card you are using and if it comes out of the box with any OC settings is kind of useless unless you have that exact same model of card.

My MSI 750ti OC 2GB running at their recommended 1145 MHz GPU/1675 MHz Mem and for 3 of my 4 cards that works flawlessly (~295 khash/s). Card 3 seems to not be able to handle that, but I scaled it back a bit until it was stable and figure it is just not a perfect card, but haven't had time to delve any further into that.

I also have two MSI 750ti TF 2GB running at 1210 MHz GPU/1675 MHz Mem. These are hashing out faster than the OC model, and run a good 14 c cooler even at the higher speeds (~325 khash/s).

Unless you have the exact same model the other people's settings will drive you nuts not being able to match... it took me a good two weeks to understand why I couldn't match the settings others were using, but it was because my card was pre-oc'd and only needed another +31MHz on the GPU to get the same settings.

Hope that helps.

Put on all T5x24 , run the 4-12 version  , overclock them to 1250mhz core and 3100mhz ram and you will have about 300 for all. And run x86 version the most important.
I have 6x750ti overclocked and set to T5x24 and that is the optium , If you try all different cards with different setting you will end up crazy.

That's what I did as well.  I run the 2-28 version for my 650 Ti BOOST and the newer version for my 750 Ti.  Did see a slight (less than 1%) bump in khs on Scrypt with the new version using the same clock settings.  I'm still closing in on the 300khs speed, up to 297khs running stable at 65C now.

that's Gröstl.

it's also a finalist of the NIST SHA-3 hash function competition. Gröstl is an Austrian dish, but because the hash function has Danish co authors, they replaced the ö with an ø like in Smørrebrød

the hash function is important because it is part of Quark and X11 - and it appears that in particular X11 will play a major role in the future (when ASICs have ruined scrypt for GPU miners)
