CCminer(SP-MOD) Modded GPU kernels.

Great improvements on all my 750 Ti's, thanks for the awesome work!

But you should check the results on the pool.

Looks like I have to rollback the last commit.

Nicehash seems to have problems, because all my rigs are showing a lower rate. With the new miner and the old miner. Perhaps another difficulty issue.

With commit 929 on nicehash my 4 rigs (960, 2x750ti, 2x750ti, 2x980gtx+960) working good.
PS. With last commit any changes to --diif make only 50% nooo.

I'm monitoring my hashrate on hashpower.co, it currently averages at about 70% the expected value.
Will keep it going for some more time to see if it's just bad luck.

POOL RESULTS--

NiceHash pool results miniing Quark are ~20% less, although locally my 750ti cards report higher hash rates.

yes, it looks like the last quark commit is breaking the hashrate. I will take a look tonight after work.

[zTheWolfz]

Note takes 25 accepts and above to see top hash with R61, -X 15 out of memory on my 960 14.9 works 5835 h,

w/ no -i/-X set 5811

-i 19.4 is the sweet spots for my card and R61 gets best top hash 5860.
anything -i 19.7 or above get lower hash rate 19.9 out of memory.

All test where done with 100 or more accepts. Edit: Stock clocks on the GTX960 SSC. W7 64bit.
Algo: lyra2rev2

can you test release 60 on the gtx 960(lyra2v2)? Wich is the fastest?

[zTheWolfz]

61 is a little faster for me, 60 5831, 61 5860

r60 command line:  -d 0 -l 16x24 --api-bind 0 --cpu-priority 2 --diff 2
r61:  -d 0 -l 16x24 --api-bind 0 --cpu-priority 2 -i 19.4

Off topic but what is 10k of PXC worth these days?

Edit: I test 61 now without  -l 16x24 to see what is better.
Edit2: Looks like I lose .005 to .008 without that line.
now .020 must put back lol


Edit: again, any help to run my GTX760 on lyra2rev2?
also have 660Ti these older miner software just doesn't cut it anymore.

PHOENIXCOIN (PXC)--

A Neoscrypt coin, 10,000 PXC was worth 0.0088 BTC when I checked 5 minutes ago on Cryptsy.       --scryptr

well I have 330,000 should be worth a couple beers huh?  

Thanks!

Hanging on maybe worth something some day. Lots of solo mining for those.

The -l 16x24 is only for the scrypt algorithm. Should not make any difference on lyra2v2

What's the problem with your 760 TheWolf? I think I missed that part

[zTheWolfz]

No good software to mine with that I can find, well that does them justice.
Most of these new coins the old miners will not work those and no one is keeping them updated that I can see.

[antho281]

The compute capability of the 760 is only 3.0 according to https://developer.nvidia.com/cuda-gpus
I don't think any mining software still support that low :S

And there really is not reason not to, there not really that old and can still do some good days work.
Even the 660Ti could still work well if we had some support.

[antho281]

Does it work if you try that change in makefile.am

From :

nvcc_ARCH = -gencode=arch=compute_52,code=\"sm_52,compute_52\"
#nvcc_ARCH += -gencode=arch=compute_50,code=\"sm_50,compute_50\"
#nvcc_ARCH += -gencode=arch=compute_35,code=\"sm_35,compute_35\"
#nvcc_ARCH += -gencode=arch=compute_30,code=\"sm_30,compute_30\"

to :

#nvcc_ARCH += -gencode=arch=compute_52,code=\"sm_52,compute_52\"
#nvcc_ARCH += -gencode=arch=compute_50,code=\"sm_50,compute_50\"
#nvcc_ARCH += -gencode=arch=compute_35,code=\"sm_35,compute_35\"
nvcc_ARCH = -gencode=arch=compute_30,code=\"sm_30,compute_30\"

EDIT: that's the mod I found a few page ago to make my 750ti (Compute 5.0) to work again with the new releases

I don't think it'll work.
There is specific code for compute 5.0 and up in this fork (assembly, launch configs, etc.).
You can try it, some algo may even work, but most won't.

EDIT: ccminer-lyra, the djm34 fork, should work with older cards but, afaik, only compute 3.5 and up.

[antho281]

That's what I thought, but couldn't figure out where I read it haha! Thanks for the info pallas!!

CUDAMINING--

First, there is a repository of CudaMiner and of the original CCminer builds and variants at "www.cudamining.co.uk".  Also, check Epsylon3's github.  He attempts to maintain compatiblity with older nVidia chipset architecture.

I think Bombadil's CCminer v1.02 supports Cuda 2.0 and up.  You will find it at the CudaMining website, linked above.  The author of the CudaMining website is going to let the domain expire, so you better check it out soon.

The old builds won't have all the latest algos, but as SP_ and tpruvot (Epsylon3) have done, you or another coder could fork and improve upon the old code base.       --scryptr

Ya works with quark but no luck getting to run lyra2rev2 on the 760.
I'm working quark on the 660 as well with it.
Heck one 660 or 760 out does 2x R270's time and half with the latest sgminer for those.
I have 4xR270. and a few 5850 and 6870 setting doing nothing. Pair of GTX480 collecting dust on the shelf.

@ --scryptr I've already looked around and already have the most updated ones I could find. downloaded, thanks.

it wouldn't be too difficult to get it to work with compute 3.0 and lower, just need to get rid of shuffle instruction and ldg ones...
