CCminer(SP-MOD) Modded GPU kernels.

[sp_]

I'm not sure if you caught my earlier message about releases.  When you made the r26 commit (86dd73f) and updated the version numbers in cpuminer-config.h it only reflects this change for windows builds.  The first line of configure.ac needs to also be changed for linux builds.

I will fix it later.

I am working on a private spreadcoin miner. Anyone interested in paying for a boost? 30-40% faster

100MHASH spreadcoin earnings with the current difficulty:

Calculation result:
Calculating for period:   Day
Coin mining:   358.83607091 SPR
Pool fee:   0 % / 0 SPR
Coins to get:   358.83607091 SPR
First exchange to BTC:
Exchange rate to BTC:   0.00028005 BTC per SPR
Exchange fee:   0 % / 0 BTC
% for transfering to wallet   0 % / 0 BTC
I'll get BTC:   0.10049204 BTC
Exchange to USD:
Exchange rate to USD:   285.512 USD for BTC

I'll get USD:   28.69168332 $

Spreadcoin pays 5-10 times bether than x11 mining per MHASH.

I tested version 23 on the 980 and it made 15.5 MHASH on stock clocks. but build 26 should be faster.
13MHASH@970 is very good.

Sgminer does 5.6MHASH on the AMD 290x

They're Gigabyte G1 cards so they should be a bit higher than most, but I haven't had a chance to verify that's the rate the pools are getting.  If so, good job.  If I can manage to keep my 12 750s and 2 970s running on the positive side of profit that would be great and I'll donate what I can, but it may come too late since I might need to sell everything for cash soon Too much lost btc in scams, exchanges, and bad timing recently.

how much?

I second this question...

[tbearhere]

Submitted the optimized blake kernals to gihub.(25% faster)

I had to split the kernals and implement 2 seperate implementations. one for the x series. x11,x13,x14,x15,x17 and one for the others, quark, nist5, jackpotcoin etc. In the x'series implementation I moved some precalculation  from const mem into the instructioncache. I also improved the uint2 implementation.


Building release 26

results on 750ti: (up from release 25)

x11 +30-50 KHASH
quark +50-100 KHASH


970 and 980 untested. Please test if you have time

100kh more quark 750ti. good job.

[tbearhere]

I third that.

Yes your right.

HI,

How much with one 750ti?

Thx

I am now rewriting luffa to work on 64 bits(uint2) simd style. 2 hashes instead of one per iteration.

Expect another boost in x11.

[kaltar]

Any Idea why this happens to me all the time

Press any key to continue . . .

and than when i restart it, speed drops to 5kh/s


Thanks

Looks like a driver crash. Download the latest driver. But could be that one of the risers are missing power, the card is to overclocked. The PSU is not strong enough. Try to disconnect 1 card and see if it still crash.

[kaltar]

Single card, no risers, it is overclocled, tonight i will see how much power it draws, it`s a gtx 980, and a 650w psu, should be more than enought for a single card.
i might be pushing it to much, i will also reduced the OC a bit. also the drivers are 344.75

[sp_]

Looks like you pushed it too hard yes.
Use a tool like GPUZ to messure the temperature. Open the case if the card is too hot.

wich card model, and wich algorithm are you mining?

Didn't work. :/ slower with 2 pipes and uint. uses more registers and codesize is too big.

Upgrade to 347.09 drivers.  They've been a lot more stable for me with these recent ccminer builds.

its a Asus Strix OC 4gb GTX 980 and mining quark

You should really PM questions like that.

i dont agree with that wolf ... i believe if there IS a price that is willing to be worked AND there are people out there willing to contirbute - then why not make it public? ...

i for one am more than happy to point my miners as a donation ... but am more than happy to 'fund' the 'private' release before it goes public ...

people like you and sp and djm - just to name a few of teh devs here - deserve to be paid for the amazing work you guys do ...

i have just taken receipt of 30 x gigabyte 750ti oc non-powered cards yesterday ... this being the first shipment of the new farm i am building as of today - and will be willing to put the entire farm 'where my mouth is' ...

make all the costs public i say ... and if someone is willing to 'contract' you - THEN its a private pm discussion ...

this is just my small btc worth ... but it is an opinion that i am willing to back ...

i admire the work you guys do ... YOU all help US ... so damned if any of this is going to go private with me - unless you are working for me ... hehehe ...

phew - now i got that out ... ccminer! ...

after the new implementation today of these cards - ill setup the latest git pull - compile and start testing ...

seems ive missed a few tests that everyone has done since ive been interstate the last few days ...

catch up time - the the farm build ...

My 2-bits worth --


First, I've tried quark mining for the first time.  My fast rig runs at ~6mh/s per card, a tiny bit less on average.  My slow rig runs at 5.7-5.8mh/s per card.  My slow rig seems stable with v26; I am trying each version as it becomes available.  This rate is greater by at least 100kh/s per card than my stable fallback, tpruvot's 1.5.2-git.

Second, I think these new algorithm developments are great.  I think older developments, like cryptonite and M7, should be folded into the mix, also.  And, for the donations, there should perhaps be a minimum contribution publicly stated for receipt of software benefits. 

Thanks for the hard work.  If I understood the coding better, I would be trying myself.       --scryptr
