Nvidia 750 ti? looks promising

kris_davison

Does anyone know how hard these are to setup? I’ve heard u can’t use riser cables? And possibly mess with voltage to get the 250/280khs

I’m not sure I’m up for that unless its a bit easier than that :-)

And if we can’t use risers… can we cram as many as we can on one board?

I mean, there’s only one fan on 'em:

They couldn’t get that hot, right? RIGHT?! :P

WHATNOW? this was new information for me?

Why not use riser cables? how else are you gonna supply em with 60w each? where did you hear this?

Wondering if i should buy me an 6pack of these, have an spare mobo (asrock h61 pro btc),corsair 800w psu, cpu and mem just laying here after not going through with my latest 280X build.

Think I read it in this review.

http://www.tomshardware.com/reviews/geforce-gtx-750-ti-review,3750-17.html

Not sure if it’s true but it says the cards can get up to 60watts direct from the pcie but I’m sure it mentions risers somewhere?

kris_davison

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)

MrWyrm

What made you go for the gainwards?

MrWyrm

For gaming, Gainward are the only thing I’ve used for years. Their 750ti doesn’t have the 6pin power though does it?

MrWyrm

I thought the 6pin only added stability?

MrWyrm

Is there any more room for overclocking or is your card pretty much at it’s limit?

kris_davison

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.

kris_davison

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 :-)

kris_davison

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.

kris_davison

Ah great I’ll have a try today see if it gives me a better hash rate. :-)

eaxvac

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.

MrWyrm

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.

vizay

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)

Wellenreiter

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
