I have two rigs with a 750ti in them each. Im getting 2.3 mhs on one and 1.3 mhm on the other. That seems a lil low to me. Anyone with 750ti can chip in some info?
@olliec420 switch to Ubuntu. Eth mining on windows with gtx750 is broken and is not likely to be fixed anytime soon.
I had a terrible time with ubuntu, i tried it before and got all the way to sending the mining command and got all kindsa errors. it was saying the libsecp256k1 library wasn't there and no matter what i did to add that it still didn't work. i am not linux expert but not a novice either as i use OS X command line form time to time.
Im going to spin up this topic in a new thread for support on that, but can someone tell me what i should expect as a hash rate from 750ti on ubuntu 14?
FYI: Don't go with Ubuntu 15.04 if you're mining with AMD cards. 15.04 only supports newer Omega drivers (15.x) which are 10% slower with Ethereum mining compared to 14.x Catalyst drivers on Ubuntu 14.04.

thanks for saring this valuable piece of information. i was already suspecting issues. the prorietary drivers supplied by AMD are only targeted for 12.04 and 14.04 LTS versions (officially).

You sure about that?
Because my 280Xs are @ 25 MH/s and my 270s are @ 17 MH/s on 15.04 with 15.x drivers.

Try 14.04 with 14.x drivers and you'll get 27.5 MH/s on 280x.

I'm pretty sure it would be the same on 15.04. 95% of my cards are undervolted to 1.037 which of course drops the hashrate a little, but creates massive electricity savings.
In fact I'm 100% certain that if I ran them at the stock voltage of 1.200 (for these particular cards) their performance would be the same as the 14.x drivers.
If you don't care about your hashrate/(kW/hr) rate, then by all means run at factory voltage or even overclock the cards. But, if you have to pay for your electricity, then undervolting is almost always going to win in terms of balancing performance vs cost.
Be careful undervolting. It affects the propagation time through logic gates and may breach required setup and hold times. The impact can be subtle errors in the longest path, usually in the ALU. The result could be bit errors in calculations.
@kenshirothefist , is that for Linux only? Is there a Windows equivalent?
Not sure about Windows. But I did tests on my own with Ubuntu 14.04 + 14.x dirvers and Ubuntu 15.04 + 15.x drivers and I lost 10% of performance when switching to Ubuntu 15.04 with 14.x drivers. @ all others: try yourself before saying it does not affect speed ... and report here if you have a real case experience. BTW: the issue is also that 14.x drivers are not supported on latest 15.04, therefore you don't have any option to install 14.x drivers on 15.04.

Sure. It's not like you just undervolt and walk away. LOL These things take time to tweak. For now, my actual daily earnings are right inline with or slightly better than estimates. So things are working (TM).
ok, i`ve just done 30mh/s spot. 7970 - 975960/1250, win64. 31mh/s will try to simulate the conditions with other mining rig. here is the proof .....
output of dwarf for 1*7970 (960/1250) - 28.60mh/s output of dwarf for 5*7950 (950/1250) - 149.80mh/s
PS I`ll try to push out more.
Nice job @trotol could you share which miner are you using and do you use any special flags? I still use the old cuda miner for ocl with batch size etc.... Thanks

That temp. would be a dream
This is the test rig with lonely 7970 in it - 960/1250, 1.013v - according to msi ab oc-tab. I had to do several tweaks to reach this level of speed, but I need more time to complete my experiment.
Hello from the always drunken Russian) The available 4h280x, 290 and 7950 would be desirable Fábregas maximum Mhs. Prompt what to choose: Windows 7 (64), or Linux? What can affect the receipt of maximum Mhs?

Cuda-miner works well under GNU, ocl-miner is for win-mining system.

stilt is cool, I think that along should bring it to 25-27MH. I am also curious to see the catalyst and miner config to keep the temperature that low with great hashrate.
It's making my room too hot in here, low temperature and high hashrate will make my room cool and quiet.

What speed are you getting for 280x and 290 with this miner?
Thanks
Im running windows btw.

inner mean: 7718684 H/s
Phoning home to find world ranking...
?
23MH/S?
I am correct?
What brand card?
Are you running the card at factory settings? You can improve the numbers a bit by making some tweaks, if you are interested.
min/mean/max: 17.8/18.2/18.6 MH/s
inner mean: 18.3 MH/s
Linux / Ubuntu 14.04.3 LTS / Intel Core i7-3930K / ethminer version 1.0.0 (Build: Linux/g++/int/Release)
min/mean/max: 0.344/0.434/0.503 MH/s
inner mean: 0.440 MH/s
Because my 280Xs are @ 25 MH/s and my 270s are @ 17 MH/s on 15.04 with 15.x drivers.

7970 -
975960/1250, win64. 31mh/swill try to simulate the conditions with other mining rig.
here is the proof
output of dwarf for 1*7970 (960/1250) - 28.60mh/s

Are you using the latest windows daily build? Or cuda-miner fork?
Cheers
Do you mean a flashing the bios? Of course, the cards are flashed with stilt bios.
