CCminer(SP-MOD) Modded GPU kernels.

[sp_]

quark: ~5550kh (on release 31 is ~5600kh) up to 61% of modded TDP 65w (cool)

But the 50KHASH drop needs to be investigated. Not so many changes in quark. More in the other algos. Thanks for testing.

What rates are you getting in x11?

~2830 khash/s same on release 31 and 34 (as miner shows). Have no long run to test pool shown rate
d = 0.02

try d=0.01 or d=0.005. Or empty diff parameter.
I get a higher hashrate. but my rig has more than one card.

[mig]

yeah. It might work on compute 3.5 though..

Use this version (1.5.2-git)

https://bitcointalk.org/index.php?topic=770064.0

it works.

yes, it works. Good in "fresh".
Strange but for "quark" on compute 3.0 original ccminer 1.2 is the best, just for fun

ccminer-rel1.5.2-cuda7-x86 is somewhat slower than ccminer-rel1.5.1-vc2013-x86 on both gtx660 and K4000, except for lyra2 and fresh, where it is the same.

I still don't understand how and why K4000 gets less hashrates than gtx660. 

For the original ccminer 1.2, Nod32 reports it is a "Win32/CoinMiner.TD trojan", so I haven't tried that.

Currently testing on fresh.suprnova.cc - looks good at first.

that is your pool is it not ocminer? ...

chrysophylax hi   I'll answer for him...that is his pool and he has many setup for older coins too.

yeah, looks like a little bit more in miner ~2930. and a 5% "reject reason: Invalid job id"
upd: rate is floating - now again closer to ~2850

Interesting to see bitcoin (sha256) support added.  No chance of profit but fun to have most of the algos supported in one miner.  Of note, this doesn't seem to be a very optimal implementation.  With cgminer (opencl) I was getting about 405,000 kh/s on my 2 x 750 Ti setup.  With release 34 ccminer I'm down to about 345,000 kh/s.  Still, it sits at the very bottom of the profitability list with either hash rate so I'm not too concerned.  It burns many more times in power than it earns.

The code was added by klaus-t. Probobly a pure C port without any cuda.
The code could be optimized, but it doesn't matter.  Even if I manage to push the speed to 1GHASH---> not profitable.

But perhaps I will try anyway...

I will add some more speedup in x13,x14,x15 today.  Similar to the fresh/x11 optimalizations. Divide the stream into two streams and run in paralell.

Nobody mining x11 anymore? what rates are you getting? (ppol vs miner) (970 and 980 is untested so please test)

Use a low difficulty

on nicehash.com you can add the difficulty in the password like this: -p=d=0.02

Build v34 --

I get 5300kh/s on x11 with my GTX 960, and on quark, 9600kh/s.  Very stable on Win 7 x64.  What are your default Intensities in v34?      

My AMD 280x cards get 6.6mh/s each on x11.       --scryptr

Last night I was running tests (v34) with nicehash and a difficulty of .01.  I was seeing ~5,850 KH/s (2 750Ti's, no overclock), which was the same for the v30 release.

Klaus_t implementation was pretty good, but the launchconfiguration of the kernal was way off. I submitted a 17.5% speed increase to github. (750ti)

What does your algo command look like...  -a bitcoin  .......? Its nice to know that we can mine BTC.

[sp_]

Yeah. 200mhash  on the 750ti. You can solomine and wait for the jackpot. One block is 50 btc. Good luck:)

[Handofmidas]

Just tried release34 for my GTX 970 @1500/7000. No change to previous releases at pools with vardiff.

However, mining at pool with low dificulty leads to hashspikes when shares are found quickly. So the hashrate is still at 8.5 MH, but occasionally spiking up to 10.9 MH, which leads to an average of about 8.8 MH. I guess this release is best for heavily overclocked GTX 980 cards mining at a pool with the lowest possible difficulty. Good luck with testing everyone.

Edit: Values for X11 algo

Hah! 17.5% increase puts it right at the 405 mh/s I had with the OpenCL miner.   

If all the ASIC miners out there suddenly brick themselves we'll have a nice GPU Bitcoin miner here.

Thats correct, thanks tbearhere, the freshcoin pool is running for a long time already, yes.

lyra2re algo appears to be broken in latest release

[bathrobehero]

Yeah. 200mhash  on the 750ti. You can solomine and wait for the jackpot. One block is 50 btc. Good luck:)

Haha, now we only need 1,677,721,600 pieces of 750 Ti to be close to a 51% attack.

I noticed this as well, though I only tried it on Westhash (Nicehash).

Edit - I meant to say I only tried yaamp...

I think the code could use some more work.

https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison

apparently the AMD radeon 7970 can do 815 MHASH with 214watt.

But I will not spend any time on it. Bether to focus on algos that still give a profit..

F.eks the Spreadminer

lyra2re algo appears to be broken in latest release

I noticed this as well, though I only tried it on Westhash (Nicehash).

lyra:
release 34 - not working, only few khashes rate
release 31 - working near ~860kh but consumes a lot of cpu
release 32 - the best, ~860kh, near zero cpu consumption
