With such a low TDP on these cards, you've got to wonder why nobody's doing a single slot card. These big dual slot dual fan coolers seem to be big time overkill for the 750Ti.
You will probably see some in the future and probably a few passive ones too but my guess right now is that it is just cheaper.
So much for NE vs AZ, least NE has some 750ti's whereas Amazon is saying 2-5 weeks.
That said the Gigabyte windforce looks good and it's shorter then the ACX.
Tom's says 7.5, Gigabyte says 8. The ACX is 9.5.
Never owned a Gigabyte card but they look to have quality with their ultra durable II.
Both have 3 year warranties and both are roughly the same price.

^^ Gigabyte card warranties are also transferable between sellers, no questions asked. They just want the original invoice.

EVGA is the same. Neither require the original invoice, only the serial number.
BTW, what configs are people finding useful on the 750 Ti? Using cudaminer, obviously, but I've tried a pile of auto-tune options, a number of variations on a theme, but keep coming back to T5x24 as the best performing.
Which is...kinda strange.

That is what I am using, I suspect as maxwell becomes more popular that more improvements will be made to cuda miner. It is still a very new architecture and prior to it there wasn't much puch for development of it because nvidia stuff was terrible.

Has anyone tried it with CGMiner yet?

NVidia cards do not work with CGMiner unfortunately as CG/SGminer are OpenCL only (at least for now).
CG/SGMiner need to include a CUDA kernel.

Highly doubt that would be worthwhile considering GPU support in cgminer was killed off months ago, and it never worked very well for NVIDIA anyway.

Referring to the creator dropping scrypt support after version 3.7.2 focusing exclusively on ASICs/FPGAs.
I was interested in this as well, but based solely on the comparative cores vs TDPs (25% more cores for 9% more TDP) it seemed like the efficiency was better on the Ti's without having any real life data to go on.
Also I want to be as effective as possible on as many algos as possible, and from what I'm hearing more vram helps quite a bit on some scrypt-jane based algos.
I have three EVGA FTWs coming tomorrow and one more beginning of next week, so between me and a few others we should have a few more data points on little Maxwell here in a week or so.

Yeah, AB shows 2 cards with memory OCs and 1 without, most likely the issue for lower hash. AB doesn't number my cards the same way cgminer does, guessing it's the same with CUDA miner.
Good call, I was figuring it was something like that.. I was going for the gusto...lol.
Dropped mem overclock to 460 and all clocks are the same now.. thanks!
Yeah that is anoth 40kH better than nothing that is for sure.

If your cards don't all overclock the same you can do them individually.

Got my EVGA 750 Ti SC in the mail yesterday, and installed it in a Lenovo at my dads' shop.
It has a 2.6GHz Core 2 Duo, 4GB of RAM, SATA HDD, Windows 7 Pro, and the 750 Ti. Overclocked, draw at the wall with a Kill A Watt is 120w! Pretty awesome. That computer just has a stock 280w PSU with 18a on the 12V rail.
So far, rock solid at 300MH/s for the last 12 hours.
So needless to say I ordered another EVGA 750 Ti this morning for the other Lenovo he has
Now I'm out of PCI-e slots available. Hopefully the bigger Maxwell cards come out soon as I can capitalize on them.

Anyone getting any cudaminer errors where the watchdog timer in windows kicks in and causes cudaminer to enter an endless loop of errors? I know it's related to having a monitor connected to one of the mining cards, so I'm hoping that disconnecting the monitor will fix the issue. I took the -i 0 command out of the .bat file, I'm not sure if that will help or hurt me.
Anyone else?

I get endless errors if the oc isn't stable.

I was going to say no, and then I remoted into the machine with a 750 Ti and was getting the errors! I backed the OC off a bit, going to see what happens. I had been running for almost 24 hours at +135 +650. Put it back down to +100, +600 and am still getting the same hash so we'll see what happens.

Yup, cgminer 3.7.2 dates back to last November. ckolivas completely dropped support for GPUs after that version.
There's sgminer, but they're really just getting started with their fork.

Would you mind sharing your cudaminer settings?

No problem. Here yah go.
cudaminer.exe -o stratum+tcp://pooladdress:3333 -O username:x -i 0 -l T5x24 -C 1
I'm currently 24 hours stable at +100 GPU/+600 VRAM. Still a little above 300KH/s.
Thanks! I'm still a little below 300Kh/s per card, one is in the 290's and one is in the 280's but it's better than the 250-260's they were at stock
How much have you overclocked them? You need like 500+ on mem speed to get close to 300.
Where do i OC? Im very new to nvidia mining.
evga precision X or MSI afterburner both work very for OC'ing the cards.
Precision X doesn't seem to support more than 3 cards though so if you have more use MSI afterburner.
The '-C' setting has no effect on the Maxwell core, so you can drop that one. (You do need it for Kepler or Fermi, though)
I think you'll like adding '-H 1', though ...especially if you have a fast CPU. That helped me a BUNCH.
My pentium G3220 didn't like -H 1 hash rate fell to like 90kH/s each and cpu was maxed out.
Yeah, it needs a fast CPU. I have an i7-2600K at 4.5ghz, and -H 1 added about 25 khash/s to the 750 Ti (didn't seem to make as big a difference on the 680, but the 750 loved it).
And yup, it hits the CPU surprisingly hard. From basically 0% CPU usage on cudaminer.exe to 10-20% usage.
