Oh mannn,I think I bricked my card...Too much load,i guess 80C was too much heat. Damn!

I've been running some at 95 deg... And no fatalities yet :-)

What card is it? I havent seen my 750Ti's hit 60°C yet, but its only running a low overclock on stock bios. I know moat nvidia gpus are designed to keep clocking themselves up even to 95°C and still keep going. When it becomes an issue they start to clock themselves down

Look Christian!  It's a "CPU ONLY" coin... go get 'em!

we only have 1 out of 4 algorithms in our crypto toolbox so far.

I think we're going to skip that one.

Hi,  I m trying to mine in solo... But i'm not sure if i'm effectively mining..

Cudaminer window:

Gpu 0: Geforce 750ti 147 kh/s
DEBUG: got a new work in 1 ms

is everything correct?

thanks

What are you minig?

[Horifatto]

What are you minig?

Kimocoin... the difficulty is near 1

[liomojo1]

yes it is perfectly normal for this coin!

Anything I should tweak on my 2 x750ti system mining HVC? Getting around 22mh/s but seen a few on here around the 26mh/s mark...

ccminer35.exe -t 2 -a heavy -v 512 -o stratum+tcp://hvcpool-apac.1gh.com:5333 -u wallet -p x

the only thing to really do is overclock your cards

[cbuchner1]

the only thing to really do is overclock your cards

and maybe to run two instances in parallel, bringing your GPU utilization closer to 100%

[bigjme]

was it -d 0,0 to run 2 instances christian? i tried it a few times and was getting 17khash/s on heavy lmao

[liomojo1]

no, 2 separate instances. -d 0,0 reduces performance.

[bigjme]

no, 2 separate instances. -d 0,0 reduces performance.

thanks, i thought it did

[Horifatto]

thanks you man

Think it may be time to mess with my gpu clocks.
I am getting the following results for anyone interested in heavycoin performance from 750Ti's

Stock Clocks
All cards are clocked at 1201MHz, with -502MHz memory. And i am running 2 instances for each card;

Card 1: 12MH/s
Card 2: 11.5MH/s
Card 3: 12.1MH/s

all cards are the same make, which proves you shouldn't expect the same speed from all cards
Power wise running 2 instances per card instead of one gained me an extra 1.2MH/s and sent power usage up by only 3W

Overclocking
Pushing all 3 of my cards now to 1303MHs, still on the stock power bios, with 2 instances per card

Card 1: 12.7MH/s
Card 2: 12.8MH/s
Card 3: 12.7MH/s

Power usage went up by another 3W however this time gaining 2.6MH/s
All to give me a massive 38.2MH/s for a GPU power usage of 153W!

as a reference, i know the cards easily clock to 1400MHz so i still have head room

Effect on temps
Right so some people have been questioning about temps. My gpu's are sitting next to a power supply in a totally open mount, and here are the MAXIMUM temps they have hit with 3 days mining, overclocked to 1303MHz. These temps are listed in the following orders, from the one with nothing in front of the fan, to the one behind, to the one behind that. Each card has 20mm gap between the next

Card 1: 40'C
Card 2: 54'C
Card 3: 58'C

Have overclocked as high as they will go and still be stable but have some weird PCI issues. One only goes to 215kh/s, and the other is rock solid at 300kh/s on Scrypt. Both run happily at 300kh/s on their own in the 16x slot, but when I hook up the riser, the card in the 16x drops to 215kh/s max.

How do I run two instances? Just two separate .bat files and drop the -t 2 command from each or is something else needed?

My bat files look like this
ccminer-v0.5\x86\ccminer35.exe -a heavy -q -d 1 -o stratum+tcp://hvcpool.1gh.com:5333 -u wallet -p x -v 512

the -d tells it which card to use, and i just run the bat twice. My cards are all on usb risers, and you can see a rough idea of performance increase in my above post, obviously it is on HVC but gives some idea of increases

Here is my hashpower on HVC with two 660TI's

If you have MSI 660Ti than you can add 1Mh/s and get ~11500 khash/s from 1 card. If you have open case then can add (+150 core, +114 power) in AfterBurner.
Total profit for 2x660ti will be 2Mh/s -> ~23000 khash/s.
My result for 1xMSI 660Ti and 2xMSI 750Ti:

What's the clock setting of your 750ti?
Nice hashrate btw.

Afterburner
Core Clock: +250, Memory: -502, Fan speed: fixed 40%
Open case -> gpu temperature: 40-43C

what clock are your 750Ti's sitting at? the 1400MHz mark?
