The recent release of the Nvidia GeForce GTX 750 Ti, to be had for around $150 with a very low power draw is an interesting option for Litecoin mining. I purchased two the Superclocked EVGA Nvidia GeForce GTX 750 Ti for $149/ from Newegg (02G-P4-3753-KR)) the Superclock is just a slight boost from the factory but I OC them a little more.
ASUS M5A97 R2.0 AM3+
AMD Sempron 145 Processor
EVGA GeForce GTX 750 Ti (x2)
Corsair Builder Series CX 600 Watt (600W is ample for this setup)
Current Performance = 610 khash/s
This is setup with the latest Cudaminer, read all about it here – https://bitcointalk.org/index.php?topic=167229.0
I’m currently getting ~306khps stable per card, my setup is below. I am running a +100Mhz offset on the GPU (in addition to the stock Superclock) and +550Mhz Mem offset, i’m still playing with these but this has been running solid for ~6 hours, we’ll see, of notice, this card runs cool, @ 59c and I don’t even hear either one of them.
I have not tweak the individual cards yet so the settings are sync’d, both are running stable at 1250+mhz, I have not upped the voltage.
And GPU 2
Alright, now for the results…. Cudaminer was launched with
cudaminer.exe -s 10 -o stratum+tcp://coinotron.com:3334 -u username -p x -l T5x24 -i 0 -C 1
As you can see, these cards are steadily pulling a combined 610+ khash/s, generating almost no noise in the process (as opposed to my 5770′s in another box) and using oh so little power, but i’m not going to dive into the pawer draw of this, these guys have already done that here (http://cryptomining-blog.com/tag/gtx-750-ti-cudaminer/).
So far, this card does not disappoint, and even with interactive turned off I have no problems using the computer, in fact i’m blogging from it right now.
