no bat file but copied these settings from heavypools

ccminer.exe -a heavy -o stratum+tcp://stratum01.heavycoinpool.com:5333 -u myuser -p mypass -v 512

is that right?

theres also ccminer

https://github.com/cbuchner1/ccminer/releases?

Yup, same thing...I prefer using cbuchner's binaries, I'm not sure I trust other sources.

I'd say mine HVC for a while, watch out for rotocoin, and try to mine some vert or buy to hold.
I got to 492kh/s now, 150 on the 750ti and 344 on the 780, scrypt:2048 for VTC.

Way more power than HVC though, not sure if I can mine this all day, at least not till it's winter here.

Is that about right?

Sounds about right! biggrin.gif Can you measure power draw with a killawatt? I'm sure the 750 ti's use something like 25-30w mining hvc. Maybe less!

For what? HVC? The only nvidia miner, Christian Buchner's ccminer or whatever it's called.

Today I have installed a new EVGA 750 non-Ti Superclocked card on my main rig for testing, and liking the results so far for Scrypt-Jane and Scrypt-N mining. It cost me $140 plus shipping but I believe Newegg has it cheaper.

For both coins I tried, the cards are at stock settings. I copied almost exactly the same Cudaminer options I had for my EVGA 750 Ti SC launch configs, but made changes to the kernel settings and device names. Auto-tune was used to determine the kernel setting on each one.

First I mined Vertcoin, which auto-tune determined T8x12 to be the best kernel config. Couldn't find any other better combination. This setup has the card mining an average of 129 to 130 Kh/s, with a roughly 5 Kh/s range. My other config options are --algo=scrypt:2048 -l auto -H 2 -C 1 -i 0 -b 4096.



With Ultracoin, the auto-tune picked T4x12. This gives an average of 57 Kh/s and rarely goes outside of the 56-58 range. Config options are -a scrypt-jane:UTC -l auto -b 4096 -i 1.



I was expecting having half the memory of the 750 Ti and 128 less Cuda cores to be a big detriment to mining these coins, but not at all. I believe a 10% decrease in stock performance is worth the price savings over the 750 Ti, so if you want to get started with Cuda mining at sub-$140 card prices, this might be a good choice to go with.

Curious to see what the power draw of these cards are. Also, would you mind just running a normal scrypt coin and post the results of that? I'd be interested in getting a few single slot 750's if the power draw is low enough.

How do you run autotune?

Ivanlabrie

Rig is in another room and not connected to kilowatt. I'll get it checked in morning. Was using 430w jane and 440w scrypt

Nice, thanks!

@cc: try yacoin and cry...xD

I'm actually giving Heavycoin a go with the GPU right now. Seems to average about 3500 Kh/s with the 750, and the whole system kind of chugs and lags unlike with Vertcoin or Ultracoin. I'm not sure if there's a way to limit the "intensity" with ccminer but the program is still very new.

[edit] Heavycoin makes my cards run so quiet!

Use "-l auto" in the .bat file.

My PC crashes (BSoD) after a while of mining (usually 5-6 hours), and it sometimes turns off, and sometimes restarts. These are the specs:

Asrock H81 BTC (latest bios)
6x 750 Ti
4GB ram
windows 7 Pro 64 bit (installed all updates)
32GB SSD
650w PSU

I have attached the dump, it's related to cudaminer and afterburner. but I don't understand much from it. Can anyone have a look?

yeah I can go with 50% or less fan speed...sips power, amazing stuff!

Christian Buchner said he'll publish an updated compute 3.5 enabled windows version soonish. Should give the 750's a performance boost. He reported a 100% increase in speed in fuguecoin.

My short report on ASUS GTX 750Ti cooling. So far not so good, I'm still trying to tweak the BIOS just to get the card run stable. Anything over +400 MEM is giving errors and artifacts under Win7 with drivers crashing and BSOD. Coming from AMD mining I strive to go with Linux and setting up Nvidias has also been a pain in the ...

Now back to cooling, first you need to get rid of black scotch tape and all the sticky residue it leaves:



A blurry pic of how the card looks like after that, was trying to see if i fit 1mm thick aluminum pads in between the mem and heatsink:



I have used 1 mm thermal pads on the mem chips, these fit just right:





Finally, installing the pads on the chips:



My core temperature has raised a tiny bit even on stock clocks mining, just as Partol stated earlier. Would love to test Partol's BIOS and see if it helps in any way rolleyes.gif
