I added a EVGA GTX 750 Ti to my herd. My results so far

I picked up a EVGA GTX 750 Ti (non SC) from a defunct miner on ebay for cheap to add to an older C2Q system that has been sitting idle for a while. I had been eyeballing the small Maxwell cards since they came out to replace the GT 640 in my HTPC to make the couch gaming a little more respectable, but Steam In-Home Streaming just released and it works so well for me that there really isn't a need anymore. Anyway, I came across a good deal and decided to give the 750 Ti a shot even though I knew that core 17 was not working with Maxwell at the moment.

My results so far:

WU: 7627
Ave TPF: 00:06:16
PPD: 32383

WU: 7623
Ave TPF: 00:06:21
PPD: 31959

The card is running at 1311MHz with 1.136V on the core and 5800MHz on the memory. This is as high as the card will overclock without a BIOS flash.

I had a couple unstable machine errors initially with the memory at 6400MHz, but bumping that down cleared those up.

I am using the 337.5 beta driver.

The card is running at 59-61°C with the fan at 48% and is completely silent. The system pulls 73 watts from the wall at idle and 126 watts with only the card folding.

Show off just wait till I get my 2nd 4p going.

So for about ~60 watts you're getting ~32k ppd? Now i'm interested in getting some

126W - 73W = 53W
But how much does the GTX 750 Ti pull at idle to add to the 53W load value?

http://www.pcgamer.com/review/nvidia-geforce-gtx-750-ti-review/#null
Says it pulls 164W.

http://www.tomshardware.com/reviews/geforce-gtx-750-ti-review,3750-20.html

Tomshardware says GTX 750 Ti peaks out at a bit over 140W.
And on a different chart the article says power consumption gaming is 62W.

So the system is pulling 126W to get 32K PPD.
32,000/126 = 254PPD per Watt.

My computer with an i7-860 cpu and one 280X uses 350W to get about 110K - 130K PPD.
120,000/350 = 343PPD per Watt.
My other computer with 4770K cpu and two GTX 780s uses 615W to get about 300K - 400K PPD.
350,000/615 = 569PPd per Watt.

Before today I never considered PPD per Watt.

Oh, I've gotten to thinking about watts this year
Dark blue is this year with 10+ GPUs , light blue is last year with 3 GPUs.
I guess the 4P guys were right all along, thinking ppd/watt!
I sure would like an easier way to find actual watts per GPU doing folding, but keep doing the math, Farwalker!

I was doing my estimate based on only the card folding watts-(idle watts+few watts for what little the card pulls). Although these don't seem to be good for a farm, they seem nice to throw in random office/web machines.

Retired my old Xeon 3110 and added a FX-6300 and a R9 290 today.
I have to find a way to measure PPD and how many watts it is using.
The motherboard has room for three more GPUs.

With F@H client 7.4.4 I don't have any PPD numbers.

Install 7.3.6 client or older.

You can uninstall the client but DO NOT CHECK the delete data box and then install the older client and resume right where you left off. (I make no warranty towards this, it worked for me though)

I got a 760 a couple weeks ago and was seeing similar ppd. I recently switched to the 327.23 WHQL Driver and am now looking at 70-80kppd oc to 1290/6800. Cpu process is almost always maxed out so I think the cpu is limiting possibly. GPU temp also rose 4-5c while folding.

Just an update

I have been getting core 17 9201 WUs on the 750Ti recently that are making ~64,000PPD with no errors, warnings or failures. The card is still running at 1311MHz and total system power is still ~125 watts.

Just read this thread - pretty impressive for a sub-$150 card. My only hesitation in getting a couple of the number of slots/pcs I need to run them. And the power usage is nice as well. Maybe need to look for cheap boards with more video slots(?).
