Tips:<br>
- Samsung K4G41325FC-HC03 VRAM seems to have better results<br>
- Overclock memory to +500 or more if possible (highest stable) , most people are getting their 300 kh/s hashrates with high memory clocks<br>
- Use Google Chrome with a flash application open to force 3D mode on Nvidia card<br>
- Try using cudaminer x86 to see if you get higher hashrate than the 64 bit one<br>
- 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<br>
- Kepler BIOS tweaker should help with changing minimum fan limit on noisy EVGA boards<br><br><span style="text-decoration:underline;">Feb 28th update:</span><br>

* ~ 130 kh/s for scrypt adaptive N factor (vertcoin)<br>
* memory clocks are important , 1600Mhz -1700Mhz mem is common to reach<br>
* 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)<br>

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?)<br><br>

Crazy, the power efficiency of these things. Don't they run without PCIE cables plugged in or is that the 750 non ti?

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.<br><br>
Zotac has reference one also a dual fan one with a 6 pin.<br><br><a class="bbcode_url" href="http://www.techspot.com/review/783-geforce-gtx-750-ti-vs-radeon-r7-265/" target="_blank">Gainward Golden Sample</a> lacks one but has the spot for it.<br><br>
GTX 750 Ti is rated for 60W , GTX 750 is rated for 55W.<br><br>
The ASUS/Gigabyte/EVGA FTW all have 6 pin pci-e connectors, although that's only for stability.<br><br><br>
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 <img alt="frown.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/frown.gif">

Oh thats weak. Weird the 650ti allowed it.<br><br><br>
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:<br><br>
R9 270: ~450 kh/s , ~150W --->3 kh/s/W --> 3 kh/J<br>
$220 / 450 kh/s --> $0.50 / kh/s (not counting overpriced $260-300 R9 270s on Newegg)<br><br>
GTX 750 Ti : ~ 250-300 kh/s , ~60W ---> 4.17 - 5 kh/J<br><br>
$150 / 300 kh/s --> $0.50 / kh/s (even the GTX 750 Ti FTW is about $160-170)<br>
$170 / 250 kh/s --> $0.68 / kh/s<br><br>

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.</div>

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.

What do you mean set up?<br><br>
Just download it and run the command line from the posts above<br><br>
The only work you need to do is the tuning... and making the Pool account<br><br>
----<br>
Current pricing<br><br>
ASUS GTX 750 Ti is $154.99 <a href="http://www.amazon.com/gp/redirect.html?ie=UTF8&linkCode=ur2&camp=1789&creative=9325&tag=overclockdotnet-20&location=http%3A%2F%2Fwww.amazon.com%2Fdp%2FB00IB9P1KG%2F" rel="norewrite" target="_blank">http://www.amazon.com/dp/B00IB9P1KG/</a><br>
MSI GTX 750 Ti (TF) is $163.98 ($10 MIR) <a href="http://www.superbiiz.com/detail.php?name=MSI-750TI2" target="_blank">http://www.superbiiz.com/detail.php?name=MSI-750TI2</a><br><br>
Gigabyte GTX 750 Ti is $165.38 <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502" target="_blank">http://www.newegg.com/Product/Product.aspx?Item=N82E16814125502</a><br>
* 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.<br><br>
ZOTAC GTX 750 Ti $149.99 <a href="https://www.superbiiz.com/detail.php?name=ZT-750TI2G" target="_blank">https://www.superbiiz.com/detail.php?name=ZT-750TI2G</a><br>
* this is the single fan one, the dual fan one has pcb shot over on purepc.pl (<a href="http://www.purepc.pl/karty_graficzne/test_geforce_gtx_750_i_750_ti_premiera_architektury_maxwell?page=0%2C4" target="_blank">http://www.purepc.pl/karty_graficzne/test_geforce_gtx_750_i_750_ti_premiera_architektury_maxwell?page=0%2C4</a>)<br><br>
PNY GTX 750 Ti $160.30 <a href="http://www.shopblt.com/cgi-bin/shop/shop.cgi?action=thispage&thispage=0110040015010_BUU5165P.shtml&order_id=!ORDERID" target="_blank">http://www.shopblt.com/cgi-bin/shop/shop.cgi?action=thispage&thispage=0110040015010_BUU5165P.shtml&order_id=!ORDERID</a>!<br>
^ No PCB shots thus far as far as I know<br><br>
Palit GTX 750 Ti StormX Dual<br>
^ PCB shot on <a href="http://www.techpowerup.com/reviews/Palit/GTX_750_Ti_StormX_Dual/4.html" target="_blank">http://www.techpowerup.com/reviews/Palit/GTX_750_Ti_StormX_Dual/4.html</a> suggest reference with ferrite chokes & low RDs(on) mosfet , no 6-pin<br><br>
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. <img alt="tongue.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/tongue.gif"><br><br>

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.<br><br>

<div class="quote-block">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.</div>

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

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. <img alt="tongue.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/tongue.gif"><br><br>

My evga SC 750ti is on its way to me. Is it going to blow up? <img alt="frown.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/frown.gif">( darn

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.<br><br>
Even Low RDS(on) mosfets blow up on Radeons mining, albeit that tends to happen on the core phase.<br><br>
Have a little confidence in the EVGA warranty! <img alt="tongue.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/tongue.gif"><br><br>

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 <img alt="thumb.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/thumb.gif">

ivanlabrie , if you see any PCB shots I'm missing please post them <img alt="smile.gif" class="bbcode_smiley" src="http://files.overclock.net/images/smilies/smile.gif"><br><br><br>
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.

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.
