CCminer(SP-MOD) Modded GPU kernels.

Nicehash release. 5.1.0 version.

.bat please
Nicehash 5.3.0 activated, not 5.1.0

The fastest kernals are up to 1000% faster than the opensource. The nicehash miner contains compiled binaries that sometimes only work on windows

[sp_]

I have 6 private miners for the people who donate (donators will get updates).

1. 0.1BTC: Pentablake +100-120% (3 releases)
2. 0.1BTC: Cryptonight +10% (one release)
3. 0.1BTC: Spreadcoin +10-20% (with full sourcecode / linux compatible) (9 releases)
4. 0.1BTC: All nicehash algos optimized. 0-10% (5 releases) (x11,x13,x15,nist5,quark,lyra2v2,neoscrypt)
5. 0.1BTC: decred +18-25% (4 releases)
6. 0.2BTC: Vanillacoin (one release) (+11% includes the decred(+18-25%) (0.1 btc discount for the decred buyers)

[sp_]

I have located the problem with the decred miner on 5-6 card celeron rigs. I will release a fix in version 5. Same fix in the vanilla mod.

[sp_]

Since I have an new donator for cryoptonight I will release #2 with some fixes and more hash

I can teach you why the kernal is displaying low numbers for low difficulty shares. (and for single cards with a low hashrate)


Take a look at at
https://github.com/tpruvot/ccminer/blob/windows/Algo256/decred.cu

and line 259

      if (h[7] == 0 && cuda_swab32(h[6]) <= highTarget) {

We don't care about the 4 first bytes of the hash and assume they are 0. This is to spead up the search.

      
Here is a found decred block:(hash)      
      
0000000000000d1ec551b6e0b734dbfa31e95059aa84e50f7db2ab244499c87c

0000000 000000d1ec551b6e0b734dbfa31e95059aa84e50f7db2ab244499c87c


but when a pool asks for  a low difficulty share
f.eks find a number that is less than this:
00000ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff ffffffffffffffffffffffffffff
We are not submitting the shares that have anything else than 00000000 in the first 32 bits of the hash (why should we when we know that the solution doesn't give a block)

If I mod the kernal to search the top 32bits only (h[7]) <= Target the mining software will work exellent at low difficulty, but not so good on higher diff.. We are searching for blocks with 14 leading zero's So I believe the current kernal is good, and the pools are fucked..

Because likely every other miner does that and so we're earning that much less because of them.

Clever move from tvpruvot. He release a opensource decred miner that will only get the correct hashrate on his own pool(with a 5% fee) or solomining. Zpool.ca read my thread and reduced the default diff to 0.5 from 0.75.  With a diff of 0.5 you only get payed for 1/2 the hash that you make..  wolf0 writes thats how the pools work. I agree and will fix the broken hash in my private decred miner #5

[zTheWolfz]

r270 are getting 7mh per card with 5.1.0 version for me r270x a little more mining x11.

[sp_]

Nvidia users normally mine quark or lyra2v2, because the kernals are more optimized than x11. What are you getting in the quark and lyra2v2 algos on the r270?

I'm sorry but its not true, i dont have the code of suprnova and the problem is inside...

[pokeytex]

SP - I am not sure what is wrong with the Vanilla custom miner but I cannot get it to get consistent accepted shares on Suprnova.  Alexis's works just fine however I get constant rejects with your newest one sent to me.  I have tried a range of difficulty settings.  Any ideas?

Here is a sample of what I get:

Suprnova, Mnpool, and coinmine...

Starting to look like this is a visual bug more then a pool bug though. Would explain why I earn 25% less on yiimp and get 25% less hash on other pools. I don't think I've ever had the hashrate show up correctly with decred.

Although that in itself is weird because some people say they're seeing the correct hashrate just fine poolside.

AMD dropped the price of the Nano to $500 a few weeks ago.

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&IsNodeId=1&N=100007709%20600566293

Let's do a profit calculation..

The nano can do 20MHASH of x11

0.020GHASH * 0.15 (Nicehash payment for 1 GHASH) = 0,003 BTC /DAY

500$ = 1,32BTC

1.32/0.003 = 440

It will take the Nano 440 days TO ROI with FREE POWER. And in these 440 days we have pascal and the 14NM chips comming..

How can i get 20 mh on Nano?? I have only 7 mh

Nicehash release. 5.1.0 version.

5.1.0 is not working on x11, only 5.1.1 or 5.3.0

speed 7 mh only

sgminer.exe   --gpu-platform 0 -k x11 --url=stratum+tcp://x11.eu.nicehash.com:3336 --userpass=18dr7MAFwzUv8LwxGiTK3sNCz27UL3qKmp:x --api-listen --api-port=4050  --keccak-unroll 0 --hamsi-expand-big 4 --nfactor 10 --xintensity  640 --thread-concurrency 0 --worksize  64 --gpu-threads 1

Now it is OK, miner 5.1.0 working too
You did not sad that must be rename one of .bin files to darkcoin-modFijigw64l4.bin

Please tell me, how can i tweak same on lyra2rev2 and quark?

Did you try nicehash? Normally the  low dfficulty shares problem can be solved with adding a correct --diff  parameter. ie ---diff 256. --diff 65656 --diff 0.01. I will get back to my rigs tomorrow and can do some more testing.

[Vaccomondus]

Since I have an new donator for cryoptonight I will release #2 with some fixes and more hash

yeah waiting for it

I must test it. i have gtx 970 .

The current decred difficulty has risen to from around 270 000 to 339 146 And the payouts have declined.
I have located an issue with 5-6 card rigs and Celeron cpu's (2 cores with little cache) This problem is beeing worked on and will hopefully be fixed in release #5. (without 100% cpu usage)

VCASH is doing good:

https://coinmarketcap.com/currencies/vcash/?markets=all#markets

And is profitable to mine. -a vanilla algo. (private kernal with a 11% boost for sale for 0.2BTC. Decred buyers get a 0.1BTC discount)

VCash sp-mod #2 sendt to the donators.

I have located the bug now that caused low difficulty shares. Mine on a pool wich starts at a diff>=1

example bat that works:

ccminer -a vanilla -o stratum+tcp://pool.v.cash:3001 -u  VafRjT9uiVUasRPVdQi4KiKJJYW81BuDLQ -p x

[sp_]

I have added another

1.8% decred hash
0.8% vcash/vanilla hash

in the upcomming decred release #5 free for the vanilla/vcash buyers.

[sp_]

Decred #5 and Vanilla #3 is ready to be sendt to the donators. (0.2BTC)

Let's give the FPGA's some competition from the old Maxwell chips
