Mar 5th update
Tested cards by people on forums & CUDAMINER thread
Note that the memory may change sometimes since the board partners have approved vendor lists for memory
ASUS Dual fan- OCN (gfgrimm) , OCN (trip96)
* Samsung K4G41325FC-HC03 rated for 6Ghz , however quite a few reports of poor memory overclocks
Gigabyte - CUDAMINER dev (cbuchner1) , Crytomining-blog (six cards) , reddit
* Samsung K4G41325FC-HC03 rated for 6Ghz , may also be Hynix H5GC4H24MFR T2C (5Ghz) if you are unlucky (see Eteknix/Vortez)
MSI - OCN (dEBASERpIX) , OCN (Aurosonic) , Litecointalk (4 cards) , rickymartin06 (OCN)
* Samsung K4G41325FC-HC03 rated for 6Ghz
MSI GTX 750 TI Classic - OCN (cam51037)
Zotac Dual fan / OC (ZT-70602-10M) - https://www.ddengle.com/board_free/458015
* Hynix H5GC4H24MFR-T2C ... 5Ghz
Zotac - OCN (dotaduck) , OCN (gfgrimm)
* Samsung K4G41325FC-HC03 (http://www.overclock.net/t/1469814/nvidia-gtx-750ti-750-maxwell-owners-club/40#post_21897840)
PNY (VCGGTX750T2XPB-OC)- Betaateb (reddit , 6 cards) , custompcreview
* Samsung K4G41325FC-HC03 memory according to custompcreview
EVGA FTW (loud due to 42% min fan) - quite a few people (see http://www.overclock.net/t/1468166/gtx-750-ti-mining/50#post_21838303) , Pcper
* Samsung K4G41325FC-HC03 rated for 6Ghz
EVGA SC - martinium @ bitcointalk
* Samsung???
Galaxy GC xartic1 (OCN)
* Hynix H5GC2H24BFR-T2C , may also be Samsung (see http://detail.zol.com.cn/picture_index_1291/index12902128_465_p371284.shtml#/&pn=22 and http://www.pcper.com/reviews/Graphics-Cards/NVIDIA-GeForce-GTX-750-Ti-Roundup-EVGA-Galaxy-and-PNY-Overclocked/Galaxy-GTX-)
Tips:
- Samsung K4G41325FC-HC03 VRAM seems to have better results
- Overclock memory to +500 or more if possible (highest stable) , most people are getting their 300 kh/s hashrates with high memory clocks
- Use Google Chrome with a flash application open to force 3D mode on Nvidia card
- Try using cudaminer x86 to see if you get higher hashrate than the 64 bit one
- A TDP BIOS mod via Kepler BIOS Tweaker may or may not help , I believe it helps more on cards with the 6-pin power connector
- Kepler BIOS tweaker should help with changing minimum fan limit on noisy EVGA boards
Feb 28th update:
34W for 300kh/s claimed by http://cryptomining-blog.com/tag/geforce-gtx-750-ti-power-usage/
Feb 23rd Thread summary:
* A listing of all reviewed cards' PCBs in my post http://www.overclock.net/t/1468166/gtx-750-ti-mining/10#post_21823154
* cam's mini review http://www.overclock.net/t/1398219/official-bitcoin-litecoin-digitalcoin-and-all-crypto-currencies-club-and-general-information-thread/13760#post_21829578
* GTX 750 Ti capable of 260ish stock , can reach 333kh/s+
* ~ 130 kh/s for scrypt adaptive N factor (vertcoin)
* memory clocks are important , 1600Mhz -1700Mhz mem is common to reach
* Kepler Bios tweaker works, can change TDP limit to 65W for boards lacking 6 pin (i.e. MSI), or up to ~90-100W for cards with 6 pin and upgraded power delivery (i.e. ASUS / Galaxy GC , EVGA FTW has +35% Power limit already)
* People are getting 1.1-1.2 Mhash/s on ~300-330W with minimal optimizations for 4 card setups
* Using card value as hedge: G-sync available on cards with Displayport (Galaxy GC / EVGA FTW / EVGA SC / Zotac Dual Fan)
--> MSI/ASUS/Gainward/PNY/Leadtek/Palit didn't get the memo that it's 2014 and that only Low profile cards have an excuse for having VGA ports : they could have pulled an EVGA style move and included a DVI to VGA adapter instead.
