Nvidia 750 ti? looks promising
-
I was wrong there’s no problem with using risers. But people are suggesting getting the cards with power connectors rather than without and possibly need powered risers for the 1x pcie as it only supplies 25watts
-
Nvidia is back in the game. Yessss. I am running a 780ti and with some slight overclocking I hit 710 Kh/s on the new cuda update. Die Amd die.

Hi guys im really struggling to get my 2x brand new Gigabyte 750ti cards running on ubuntu 12.04 iv followed a few tutorials but I cant get the drivers to be picked up and used. I can at least get the screen visable by using the nvidia_current driver (304) from apt-get but with a resolution of 600X480 or whatever. terrible.
I have tried installing the drivers both through apt-get and also the NVIDIA…run file for 64x linux but no joy. wasted a couple of nights so far.
Does anyone have know a good tutorial / walkthrough or can anybody give me specific instructions on at least getting the driver installed (319 or better is prefereable)
-
What made you go for the gainwards?
-
For gaming, Gainward are the only thing I’ve used for years. Their 750ti doesn’t have the 6pin power though does it?
-
I thought the 6pin only added stability?
-
Is there any more room for overclocking or is your card pretty much at it’s limit?
-
Thanks for the advice guys but I’m still at a loss.
I can’t boot into Ubuntu using the 750ti its either purple fuzz before the kernel upgrade or a black screen after it. I tried to follow instructions using on board graphics but after kernel upgrade NVIDIA…run file failed to install due to unsupported kernel.I managed to get it at least booting up by purging nvidia* and installing nvidia-331 which got me to a terminal but no GUI.
I’m running out of ideas here. I might test the card in my windows PC to make sure its ok.
-
Ok progress I installed nvidia-319 and plugged in card again same black screen. But this time I turned off the internal graphics in the BIOS and tried again. So not the best drivers but its a start. Thanks for all the help guys. Now onto cudaminer :-)
-
Finally got it working at last thanks for your help I should read more carefully. Had upgraded to kernel 3.13 which meant driver didn’t work. So deleted that and installed kernal 3.12 and all is good in the world.
Do you have any sample cudaminer configs for 750ti?
I’m hashing around 265/267khs with no tweeking yet. I’m so happy right now lol.
-
Ah great I’ll have a try today see if it gives me a better hash rate. :-)
-
Thinking of selling my R9 280x for this… but I do hope for one with double the power consumption and hash rate as I do not have sufficient PCI-e slot.
-
I saw somewhere that there is talk of BAMT supporting PCIe spliiters in the future. Not sure if that’s pie in the sky, but that would make these very interesting.

The rest of the Maxwell series will certainly be interesting.
-
Actually thinking about moving over to these ones since the power costs are killing me over here :P (thought about switching to gridseeds for a little while but no)
-
They are running like a charm. :D
I’ve a 750 TI and realistic view shows that it gets 250-270 khash/sec in the longer average.
I found the following interesting:
- I even can use my Screen wit very little impact when the cart is mining
- setting ‘interactive’ , the -i switch, on or off didn’t have any impact
- setting GPU_MAX_ALLOC to 100% didn’t have any effect on hashrate, but the autotuning feature
came back with different settings: T14x24 without GPU_MAX_ALLOC and
T20x24 with GPU_MAX_ALLOC= 100%
This means, that the larger available memory is no benefit for the hasrate and in my opinion it also shows, that cudaminer can probably optimized to support these new cards even better.
By the way, my card is taking ~ 60W when mining at 260 khashes. The whole PC is at 140 W then :D
-
Ive just ordered another one (Gigabyte GTX 750 Ti 2GB GDDR5) which means I will still only have three but thats 3X more hashing power than I had last month give or take a few hashes.
I have it in my mind to build a new rig with 4 or 5 of these bad boys.
These seem a little cheaper but have no power cable and only one fan
anyone had any dealings with them?
-
I’m using a Gainward one.
It seems, that all 750 cards don’t have and don’t need an additinal power cable, as they are taking ~ 60 watts and therefore in the specs of PCI-E, which supports one card with 65 watts max
Gainward also has only one fan, but the fans are not that high spinning as with the Radeon.
My card is at 59° C and fan speed is ~ 1000- 1100 rpm only.
It’s hardly hearable, the CPU fan generates more noise.
-
So, a little math here.
Currently I’m running 280x cards. 1 280x draws around 250 watts and hashes stable 700, correct?
3x 750 ti will hash for 750 stable (counting low here) and draws 180 watts, correct?
So the watt / khash is 32,8% better on the 750ti…I’m so selling my 280x before people here in sweden realize this! :P
And with risers I’ll be able to run all cards on one rig even tho I’m running a corsair cx750 psu :P
[edit]
Did a little calc, with current power costs here in sweden I’ll increase the profit with 60ish percent if I run 3 750ti instead of 1 280x :P
-
Yes, that sounds reasonable.
I had one 6950 and one 6790?? running taking the system to 380 W at ~ 650 Khash
As Power is expensive here in Germany, mining was not profitable at all with diffs > 180.
I went down to 260 Khash at 140 W. and could add 3 more 750 to get back to the same power consumption,but would hash at 1 Mhash…
Just my PC doesn’t have the required slots.
