hashrates fluctates. You need to do a 24hours average to get the real speed.

yea I know just saying its all over the place right now.

I had some miner/pool diference @ suprnova ( 1.7.3 miner) too, and now it behaves much better with Decred#4(64) but with lowered intensity (30 ). Also it is more stable and around 20% more hash. That is for hash displayed. Though coins mined are usually less than predicted what I understand as pool luck.

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 00 in the low byte of the first 32 bits. (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..

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.

This would explain why I often have 3-8 consecutive submits without a Yes!  I found no solutions that met this preset minimum, it wasn't that I didn't do the work.  (single 750TI setup, for now)

Tried a couple different difficulties on MNpool, doesn't seem to make a difference. It always show up at about 75% of hash, a bit more with the CPU version of decred. I don't have super anemic rigs, they're running on quad cores. Even the CPU version doesn't always use 100% of my processor either. I'm pretty sure it's not because my processor is lacking, especially if it works properly on yiimp.

1. Use intensity -i 30 on compute 5.2 devices(the default is -i 31
2. Don't minemwith difficulty less than 1

In then next version I will reduce the cpu usage.

x11 going crazy on nicehash )) forget 'bout decred ))

The 980ti is doing 13mhash @1280 core on the 980ti with my private kernal. $5.4 a day with the current prices. Still profitable with the gpu.

your post is confusing, 5.4 a day with a 980ti mean 2.7 with a 970, which is not that good comapred to 5-6 with etheruem an other algo and btw on what coin, dash?

[tbearhere]

Also, anyone use Mining Rig Rentals for Ethereum? I've tried to get it working a few times, but Stratum is only compatible with a couple miners and not eth-proxy. Getwork seems to always give me a saw tooth pattern as there seems to be connectivity issues of some kind between the MMR and pools.




I'll check out 64bit decred later today. I swear it works fine before, but now getting the weird hashrate decrease I thought was fixed.

I get patterns like that when the difficulty ajustments from the source are to high bensam1231.

I agree, but Ethereum you can't choose difficulty. Pools are set unless you do stratum and MMR doesn't work with that. I definitely see some people with rigs with perfectly fine looking graphs so I don't know what I'm doing wrong.

This is what I get a suprnova pool.... so high the difficulty his pool sends out that my rigs stall and crash.  They work for a few minutes them a difficulty of 32 is sent then crash.

What is blake2s please?   Thx

I wrote profitable. Not the most protitable. The 980ti and the 970 make the same mining etherum. $5-6 only 22Mhash

poor nvidia.
290x is doing 16mhs on stock clocks downvolted to 1.06v. Only 250w.
Easy to get kachur miner from nicehash package ))

Works well on Linux too with some slight edits to the host miner. I pulled my BMW and merged it via GCN assembly - was faster. Guess most of his work went into SIMD.

It's nice to know there is still room for improvement on those x algos.
I won't ask you the binaries for sure, but something to help make the public ones work on linux would be much appreciated ;-)

What are you getting on your private miner for x11 on a 970?

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
