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.

Christian did you buy a 750ti to play with?

I ordered one. A friend ordered six.

one. for review and development purposes.

A friend of mine will be getting 10. His first mining farm.

Because of some product expectations I have I will hold off buying single GPU cards. I've bought Asus MARS recently and I want this kind of device for mining, but definitely Maxwell based. We need more hash power density - up to the power limit that a single PCI express card can provide (would that be 250 Watts?)

Crazy, the power efficiency of these things. Don't they run without PCIE cables plugged in or is that the 750 non ti?
 
#4 ·
Yeh cards like MSI GTX 750 Ti Gaming , Palit GTx 750 TI StormX Dual do run without 6 pin PCI-e power cables. They both have a open spot on the PCB for adding one though.

Zotac has reference one also a dual fan one with a 6 pin.

Gainward Golden Sample lacks one but has the spot for it.

GTX 750 Ti is rated for 60W , GTX 750 is rated for 55W.

The ASUS/Gigabyte/EVGA FTW all have 6 pin pci-e connectors, although that's only for stability.

Colorful (China), Galaxy (leaks look like it has a 6 pin), Innovision 3D (from their site it looks like reference PCB), PNY there's not much info on or I can't find it

Looks pretty good though. I'm not sure if the hashing power makes it worth it over the 270 since it would take so many slots but looking forward to the bigger cards.

I'd say it is worth it if you're in the USA paying > 0.15/kwh or Europe:

R9 270: ~450 kh/s , ~150W --->3 kh/s/W --> 3 kh/J
$220 / 450 kh/s --> $0.50 / kh/s (not counting overpriced $260-300 R9 270s on Newegg)

GTX 750 Ti : ~ 250-300 kh/s , ~60W ---> 4.17 - 5 kh/J

$150 / 300 kh/s --> $0.50 / kh/s (even the GTX 750 Ti FTW is about $160-170)
$170 / 250 kh/s --> $0.68 / kh/s

VTC Adaptive N factor Scrypt mining performance with:

Code:

Code:
cudaminer.exe -algo=scrypt:2048 -o stratum+tcp://stratum.vertco.in:8080 -u yourworker.1 -p password -i 0 -l T5x24 -C 1 -H 2
For VTC mining that uses Adaptive N factor Scrypt algorithm with the T5x24 configuration and manual settings got us about 950-980 KHS hashrate with the GTX 750 Ti running at stock frequencies. After overclocking the Maxwell GPU the performance increase has boosted our hashrate to about 1000-1050 KHS.

Interesting. The prices are great, hopefully they hold up. Love the no 6 pin ones. Someone posted they were only getting 550 cpm with PTS. GUess they aren't good for that.

In that tom's picture can someone explain to me how they only managed 302 khash/s on an r9 270x???

What do you mean set up?

Just download it and run the command line from the posts above

The only work you need to do is the tuning... and making the Pool account

Current pricing

ASUS GTX 750 Ti is $154.99 http://www.amazon.com/dp/B00IB9P1KG/
MSI GTX 750 Ti (TF) is $163.98 ($10 MIR) http://www.superbiiz.com/detail.php?name=MSI-750TI2

Gigabyte GTX 750 Ti is $165.38 http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502
* Gigabyte packs only reference number of phases but uses ferrite chokes instead of iron ones (plus Low RDS(on) mosfet) for the secondary phase. ZOTAC single fan might be the same way.

ZOTAC GTX 750 Ti $149.99 https://www.superbiiz.com/detail.php?name=ZT-750TI2G
* this is the single fan one, the dual fan one has pcb shot over on purepc.pl (http://www.purepc.pl/karty_graficzne/test_geforce_gtx_750_i_750_ti_premiera_architektury_maxwell?page=0%2C4)

PNY GTX 750 Ti $160.30 http://www.shopblt.com/cgi-bin/shop/shop.cgi?action=thispage&thispage=0110040015010_BUU5165P.shtml&order_id=!ORDERID!
^ No PCB shots thus far as far as I know

Palit GTX 750 Ti StormX Dual
^ PCB shot on http://www.techpowerup.com/reviews/Palit/GTX_750_Ti_StormX_Dual/4.html suggest reference with ferrite chokes & low RDs(on) mosfet , no 6-pin

I don't think EVGA is going to be any good for mining since it looks like secondary phase uses an Iron choke and d-pak mosfet like reference design. It will likely explode after a week.

I've gotten these cards to hash at 310-320kh/s for the last 12 hours stable, drawing about 90 watts from the wall per card while hashing.

Edit: I've got these cards stacked on top of each other in a desktop tower and they stay very cool. 48-60C with just the case door open and no external air movement.

With the new version of cudaMiner on the reference version of the GTX 750 Ti, we were able to achieve a hashrate of 263 KH/s, impressive when you compare it to the performance of the previous generation, Kepler-based GTX 650 Ti, which tops out at about 150KH/s or so.

Despite this, the MSI GeForce GTX 750 Gaming, with a bit of overclocking, was able to do about 159 khash/s
Quote:
To help us consistently hit 159 khash/s, we also overclocked the GPU to the same 1363MHz core / 1553MHz memory (6.2GHz effective) as we did in our overclocking testing earlier.

Other thoughts:
Due to lack of Displayport, ASUS/MSI/Gigabyte/ZOTAC/PNY cards are not adequately hedged via GPU. G-sync requires displayport 1.2.

EVGA seems like it would be a good bet until you see the PCB without the cooler, with the d-pak and iron choke for secondary phases. I'd buy it in a heatbeat except for that fact (it's a big problem when you're using memory intensive algorithms with a single phase memory that is powered by d-paks).

The GTX 750 Ti SC is the ideal card if it weren't for that (base to SC difference is the copper core insert on the heatsink). The GTX 750 Ti FTW befuddles me as the market value is $170+ and it is close to 10 inches like the MSI but only packing 3 phases for the core and d-pak + iron choke for the memory phase.

My evga SC 750ti is on its way to me. Is it going to blow up?

#13 ·
It's not going to blow up per say. I just don't have confidence in d-pak mosfets. They have the tendency to blow up on Asrock motherboards.

Even Low RDS(on) mosfets blow up on Radeons mining, albeit that tends to happen on the core phase.

Have a little confidence in the EVGA warranty!

See http://www.overclockers.com/evga-gtx-750ti-ftw-graphics-card-review


It's definitely an iron choke like Nvidia GTX 750 Ti reference board

You do need to tune settings with cudaminer to get optimal results...for instance, those graphs show 780s pulling 450kh/s, well mine does 716kh/s at 1267mhz core. It's all in the settings

ivanlabrie , if you see any PCB shots I'm missing please post them

These are typical PC reviewers, they are likely not running skyn3t bios on GK110 for instance. They're catering for out of the box performance. Tom's is notably wrong, no way R9 270 gets lower than 380 kh/s.

As far as I know, no.

"Gaming" has replaced "Power Edition"

Lightning is only reserved for top one or two SKUs (think GTX 770/GTX 680 / GTX 780 / 7970 / R9 290X / HD6970 / GTX 580)

HAWK is for mid range GPUs , this is low-mid range. Plus we have the GTX 760 HAWK already so it would have to wait til GTX 860 or GTX 850 Ti

The GTX 750 Ti Gaming is plenty powerful, if you want to void warranty then you can solder on a power connector.

Else, grab a Gigabyte motherboard with OC PEG / SATA power plug for PCi-e lanes or Asrock motherboard meant for "BTC" mining.

ahh that's disappointing. It's not specifically power capacity I'm looking for, rather I simply wouldn't be interested in mining on entry-level componentry haha. To me personally, it sounds like a RMA waiting to happen

It's only a 100 watts. So not much will happen. Should be fine.
