CCminer(SP-MOD) Modded GPU kernels.

Submitted a 200KHASH increase in the lyra2v2 on the gtx970. (2%)

No gain on the 750ti

BUILD 927--

I built commit 927 on my GTX 970 rig and began mining with it.  I found that mining on GMC required a "--diff 0.5" setting.  The cards are not running faster yet, but it is too early to tell.       --scryptr

Unfortunately...

sp, and all other mining developers, I suggest you to watch development of this: https://bitcointalk.org/index.php?topic=895020.msg12164065#msg12164065

There has to be a census reached about Lyra2REv2 diff multiplicator.

ok, here the new release, for this one you don't need to use "-diff 2" anymore: https://github.com/djm34/ccminer-lyra/releases/tag/v0.5
sp_ please update your release as well (as far as I know all the pool now use a difficulty of 256, in case one isn't using it --diff 0.5 will be necessary  )

edit: careful if you are using give-me-coin, they still use a difficulty of 128, you'll need to use diff of 0.5
would have been nice if yopu had search for a consensus among the pool, before posting that 

POOL CONSENSUS--

NiceHash and the other pools better agree.  They may be big, but they are not the best payout for Lyra2v2 currently.  Give-Me-Coins (GMC) is usually in the top 3 pools for VertCoin, they pay reliably and for a 1% flat fee.  Mining solo would pay out more, but less consistently.

Is there also an increased in 980 ti? Ok im going to check.

Last commit on quark is lower 700 kh on 980gtx... on 960 is good like is on old commits...

Submitted 70Khash more in lyra2v2 (0.5%) on the gtx 970. Merging blake and keccak into one kernal & Changing the launchconfig.

I reverted the commit "do memory writes with vector instructions" Could you get latest and test please. Don't have a 980 here now.

Tested. Speed is OK!

Submitted another boost in quark 100-200KHASH on the gtx 750ti.  400KHASH on the gtx 970. I removed some buffers and improved the cachehits in the nonce selection code. Note that the intenstiy can be set a little bit higher since I have removed somee memory allocation.

Please build again


My private kernal is doing 7MHASH on the 750ti. If you want opensource to survive. Please donate some beers and enjoy the free hash.

[sp_]

-Boost in quark on all cards (100-200KHASH on the 750ti)
-boost in lyra2v2 on gtx 970 and up
-Fixed Lyra2v2's default difficulty (double the hashrate on some pools like nicehash.com) If if doesn't work use --diff 0.5
-removed animecoin


1.5.61(sp-MOD) is available here: (21-08-2015)

https://github.com/sp-hash/ccminer/releases/

The sourcecode is available here:

Quark - +650-700kh on 980gtx, +300 on 960 - GREAT!
But on pool side (nicehash) speed down by 40%...

REAL IMPROVEMENT--

My GTX 750ti FTW cards are now hashing Quark at 6.7-6.9Mh/s.  The rig runs at 40.6Mh/s, rater than 39.1Mh/s (top). My GTX 970 FTW+ cards are still at 14Mh/s for Quark.  I may need to reload Linux and use the most recent driver.

In Lyra2v2 you don't need to use the --diff 2 parameter anymore on Nicehash.

I get correct pool results for Quark in release 61

[Slava_K]

Testing quark on nicehash - speed is down whith last commit...
PS. Try to recompile again and test.

I am running the exefile that I buildt(release 61). The miner shows 40MHASH in the client . The pool (nicehash.com) shows 35-45 MHASH as expected.

[Slava_K]

Miner show 50700 - on pool min 30, max 44. All time 36...

Looks like mine dropped to 28-45 now.. Will look into it.

I have to show (GTX960 100me) Lyra2v2 --1.5.60(sp-MOD) 6005 Mh/s ,--1.5.61(sp-MOD) 5950 Mh/s.

Run with -X 15. I reduced the default intensity because one of my win8 rigs got out of memory.

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.
