CCminer(SP-MOD) Modded GPU kernels.

[sp_]

The miner will be publicly released once 5btc has been reached.

It looks like a lot, but it isn't much if everyone participate. Now if only a bunch of people allows to reach that amount or if only a few donates, then the miner will be released privately only to those who pledge.
I think it is fair this way, it is a crowd funding project, which means everyone has to participate and give a tiny bit, it may also protect coin value...
(I'll make a new thread when I was a minute)

But with only 100KHASH on the 750ti this miner is not profitable. If you want donations, you want to make sure that the miners get's a profit.

That includes support and update... and it is already more profitable than many things around... (also tdp usage is only 80%)

good day
23-th version automaticly change -f multiplier to 0.67 even thouse it is set in 1.0 in bat file - it`s normal ?
so my hash rate in pool significantly lose
also one of two my farms on 750Ti crashe after half hour working

I think I have a fix. I will remove the code that reduce the diff in the next build. (build 24)

Difficulty is reduced in the miner, but not on the pool. This meens that the pool think you are mining on higher diff, but you only submitt low diff shares.

Looks like the best opensource miner is doing 50KHASH with overclock on the 750ti (opencl code) (Neo scrypt)

http://cryptomining-blog.com/3682-mining-feathercoin-after-the-neoscrypt-fork-with-amd-and-nvidia-gpus/

and from the user

scryptr: 3.7.8 neoscrypt on a 550ti at a rate of 25kh/s (Win64).

So your kernal is more than 100% faster than the opensource. Pretty good.

Please explain what you mean by scaling?  Should it reach the same ratio between card models as scrypt?

I was expecting something different... but actually it looks like sp_ x11 in terms of scaling

The problem with the 750ti cards is that they use so little power. When you optimize the code, the card sometimes downclock itself automaticly and the hashrate will drop.
This is why I have reduced the number of threads in many of the hashing functions. In BMW f.ex I only use 32 threads. On 970/980 on the other hand, more threads increase the performance.

     

Hmmmmm... that may explain why my slower rig slows down to a crawl and then dies.  I found it barely hashing after restarting it at good speed 5 hours ago.  Should I not use the intensity flag?       --scryptr

My 750ti rig is still going strong since yesterday  .......NO intensity setting.  
EDIT: windows 8 and #23 release.

I am still not exactly clear on what is meant by the term "scaling".  Is it refering to operations within the code execution, or with overall hash-rate performance in various GPU models/makes?

Whatever.  I have the same commandline for both my 750ti rigs.  My intensity flag is set at 20.5, the rest is address/user.  However, the faster rig (750ti/AMD FX cpu/8 gig) rocks steady with +/- 10kh/s rate of 18,425kh/s.  The slower rig (750ti/AMD Sempron 145/8 gig) starts as previously posted at 17,965kh/s and then slows to far less, maybe 1000kh/s.  It was pretty steady on 1.5.2-git, and before I started tweaking intensity.  Both have identical motherboards.

Maybe I should reload the OS?  Or maybe I should relax the intensity to less than default?         --scryptr

Looks like a memory leak somewhere, but seems to work fine on Windows. Klaus_t has removed a leak of 4 bytes per throughput in his latest checkin on github. Might help.

does it work with mono?

No idea, and I won't get my hopes up for it ^^" But it works over the network, so another windoze pc or virtualbox with windoze should work.

winblows is no option

KBOMBA-CCMONITOR-WINBLOWS-MONO-

Ok, before I even try to read the documentation, would I be able to run ccmonitor on a Win 7-64 computer and monitor a linux rig remotely?  Or would I have to run ccmonitor with Mono on the Linux rig, and view it on the Win 7 computer?

Mono appears to be a big project.  I'll be looking at ccmonitor today.     --scryptr

Lol, no, normally it should work on your windoze and monitor the linux one from there. I haven't tested it, so please tell me if something goes wrong ^^"

neoskrypt gtx 970 only 100kh ?

neoskrypt gtx 970 only 100kh ?

no idea, latest my gtx980 are doing 365kh/s

[sp_]

yaamp is currently paying 3,6 BTC/day 1 GHz neoscrypt
One single 980 mining @ 360KHASH will give you BTC 0.001296 per day

It will take a single 980 card 3858 days to earn 5 bitcoins with free power.

Don't you think your bounty is a little high?

no... because released for free it will take twice that time... (just look at vtc...)  
also I am not asking one persons to pay 5btc.
xcn miners was downloaded more than 1000times (binary version, have no idea for the source), in that scenario that would be 0.005btc/persons
don't say it is expensive...  < 1.5euros

it is a crowdfunding project. people gives what they can...

good day
23-th version automaticly change -f multiplier to 0.67 even thouse it is set in 1.0 in bat file - it`s normal ?

Difficulty is reduced in the miner, but not on the pool. This meens that the pool think you are mining on higher diff, but you only submitt low diff shares.

it`s good, but please note than -f factor in ccminer is dividing difficulty - not multipliering, against cg/sgminer,
so when ccminer set -f to 0.67, it work with more difficulty hashes (1/0.67=1.5), - not reduced

and if you comletely remove -f factor code, the miner will not working with some pools, for example with diamond coin pools

OK.  And with CGminer 3.7.8, I get 25kh/s with my GTX 550ti.  But, CCminer is completely different code from CGminer, they evolved separately.  Excuse me, not trying to be rude.  CGminer and SGminer share origins.  CCminer is designed for Cuda (nVidia) code.       --scryptr

Yes its a nice speed but honestly Its not even worth running anymore. Nothing is profitable anymore.

Today I finally solved the ccminer crash when exiting with ctrl-c. Now ccminer will exit quietly, and not with a windows error message box. I believe other crashes, also will be without the message box. This makes it easier to run i a batch script.

here is a simple example of a bat script:

:loop
C:\ccminersp-mod\ccminer.exe  <params>
timeout 30 /NOBREAK >nul
goto loop

If the miner crash, it will wait a bit and then restart
