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. tongue.gif

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? 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.

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! tongue.gif

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

Comparison boards

MSI TF (4+1 , empty 6-pin) **** May be 3+1 actually since I looked at the specsheet for uPI uP1608 on the MSI Gaming, it seems it only supports 4 phases total.

Palit Storm X Dual (2+1 , empty 6 pin)

http://www.techpowerup.com/reviews/Palit/GTX_750_Ti_StormX_Dual/4.html

Gainward GS (2+1 , empty 6 pin)

http://www.techspot.com/review/783-geforce-gtx-750-ti-vs-radeon-r7-265/

* PNY looks to be the same as Palit. I believe Gainward has been acquired by Palit as well. (source:http://www.eteknix.com/asus-knocked-off-top-graphics-card-vendor-pedestal-by-palit-and-pc-partner/ : " Palit Microsystems. They own and operate the Palit, Galaxy, Yuan, Gainward, Vvikoo, XpertVision and Daytona brands which predominantly sell only Nvidia products.")

Missing Colorful (Asia only as far as I know).

Inno3D = reference (2+1 ...iron choke with d-pak, empty 6 pin):

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 thumb.gif

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


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.

No. I Dont expect MSI to make a "Hawk" 750 Ti

Since this is slightly offtopic (Click to show)
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. tongue.gif

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.
