Same here, I tried Decred for a while and all the pools I mined at was that way except one "yiimp" it was pretty much on par with my miners.
I gave up on it and went back to x11.

What's wrong with yiimp? Is 5% fee too much for you?

Putting aside fees, I don't get anywhere close to what calculators are showing on yiimp. I get about 70-75% of what I should on yiimp. Mined there for about a day and a half.

No, I just don't have a wallet or wish to do exchange, so unless that has changed since I last had a look.

Then you mine on zpool.ca with 2% fee and BTC payouts.

no, I mined directly to there wallet for there work when I mine there. DsabMdMku2tjrDcPtkwd7tvGfyskgHMG8ex
But yes I also tried zpool & xpool for a short while a few days at each of the three sites.

then you can try zpool.ca here is the bat.

ccminer -a decred -o stratum+tcp://mine.zpool.ca: -u 1CTiNJyoUmbdMRACtteRWXhGqtSETYd6Vd -p x

In the last 24 hours Zpool has payed out 0.0116BTC / GHASH (0,0348 BTC ($14.44) for a single 980ti with the modded miner (#4) in 24 hours)

remove the d=0.01 parameter. This kernal doesn't work for difficulty below 1. remove the -l 16x24 its only for scrypt min mining.

Zpool has a diff of 0.75 wich is too low. so you might want to set the diff to something higher like -p d=4
Yiimp is starting on diff=1

[djm34]

Vanilla coin sp-mod #1 is now available for a 0.2BTC donation It includes the decred sp-mod #4. The decred donators will get a discount of 0.1BTC. There wil be no more updates on the Decred algo. You need to upgrade to the Decred+Vanilla miner to recieve decred #5.
Vanillacoin 8.5% faster: 11% faster

Nobody wants my optimized Vanillacoin kernal? You make around 40 VNL / Day on a single 980ti. (4,5GHASH)

0.012BTC = 5$

When everybody mine decred, the difficulty is going up and the profit is declining.  Then you need options. A faster vanilla kernal is a must for the proffesional miners.

Betatestesters needed. My kernal is 11% faster than the opensouce kernal. Become a donator and support the sp-mod project

that's not the definition of beta-tester, if you have to pay for it...

I've beta-tested many different things over the past 35 years "games, mining software" and have never had to pay to do work for others. lol
If anything they should pay us to test there buggy stuff as it can become very time consuming with testing  & reports.
Give me 0.1 BTC & I'll test and give feedback

I have my many test .bats with many different  parameters I use for quick jumps from one to another server or different coins when testing.
See my new title.   offer is still open....   get in before the price goes up....

Some pool owners are searching for weaknesses in the mining software to cheat you. My modded decred works best for high difficulty, but I can make a version that is excellent on low difficulty as well. Then you will get great stats at suprnova, and bad stats at yiimp.

The pool support Vardiff. and will reduce the diff for the 750ti to 1-2, wich will give bether results over time. the problem is difficulties under 1.

I had tried many different -diff in my earlier testing, maybe it has changed some to the better now as time has gone by.
That or I just didn't leave it on the higher -diff long enough in my earlier testing.. thanks for the tip.
still at any rate better than what I was seeing..

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..

[sp_]

Why should we when we know it doesn't give a block? BECAUSE POOLS WORK THAT WAY, DUDE. Not submitting those is literally burning cash. The problem isn't the pools, it's you.

But this is only a problem for single card rigs with a low starting diff. Yimp has solved it. It starts on diff=1.
But I will fix it in release #5
I will use 2 kernals. if the first 32 bits of the target is 0, run the fastest kernal. If they are not, run the kernal that case on the first bits. (and probobly disable the cpu verification)
