Nvidia 750 ti? looks promising

MrWyrm

Anyone actually know anyone who is mining with these?

Been looking at theese as they price/performance/watt are pretty damn good.

My biggest problem is that mobos only have 6 pci-e connections.

Meaning you need to build an entire rig PSU/CPU/MOBO/RAM/HDD for messely 1500khash (thinking an average of 250Khash pr card stable 24/7)

Which means your close to 1000GBP for an rig system with 6x 750TI, that makes roi time allmost 6months.

Ive returned my latest 290X and 280X investment (4x280X and 3x290X). Just cause this is interessting.

I do however not feel that 750TI is the right card. Would like to have double hashrate/double power/double price, at least then you get 3Mhash pr system. Which will really help on ROI timing.

For smalltime miners that just wanna have an rig its pretty damn great though, 1500khash, silent operation, low heat, and just plain fun.

For someone looking to scale over 20Mhash however. To much hassle imo.

I have money ready if they release an better spec GTX8xx series maxwell card however!

That might describe me.

Now if someone could only make an usb to pci-express adapter and we would be golden :D

MrWyrm

Pretty things all in a row.

Doubt you’ll be able to draw enough power from USBs.

MrWyrm

What’s to stop me buying two of these, perhaps the EVGA ones with the PCI-e power, and sticking them in my existing PC, just to get me on the ‘mining ladder’? I won’t be able to run them in SLI, since they are not SLI enabled, but could I use one of them for gaming, on the odd few times the feeling takes me?

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 :-)

HopeStillFlies

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 :-)
