The algorithms that you want to incorporate in your miner are just fine for the smaller cards.

I think the selection of pool is important here. For spminer Miningpoolhub.com and Hashalot.net give the best returns. Up to 10% bether than the other pools.

EDIT: it's --skip-stale-work

This option is only for pools that give a penalty for stale/invalid shares. F.ex the Supernova pool. Every time you see a skipped solution, you loose hashrate poolside. Supporting p2p pools is difficult because of the rapid difficulty changes and low difficulty. It requires tuning and codechanges to perform well. For low difficulty you usually need low intensity. A high intensity meens that you give the gpu alot of solutions to search for in each bulk and this can take a few seconds to complete. This approach is good for solomining and high difficulty, but not good for rapid difficulty changes and pools with low diff.

But surprise surprise. miningpoolhub just see the opposite and paid accordingly!  Giving spminer card a 10% $$ advantage compared to the other two.
It was 24 hour, so it can't be luck. And its enough clear for me.

Poolside +10% faster than the Team Red and the SRB miner...

First tests with the ethereum miner show promising results. A few percent faster than the competition.. More profit in the pockets of the miners.

only weird thing? your 1 % seem to be 1 % but it comes in a weird way in one big shot

The fee normally mined in the first few minutes of mining, then you get around 12 hours of mining without fee, and the fee repeats. Good results with Long term mining and rigs that doesn't crash. The competion is mining a few shares every hour here and there.

Okay I see.

We ran into some issue with SPminer on the p2pool after a while as well. For some reason after a long time the ping goes crazy high.

I did a lot of trouble shooting, and the only thing that fixed it was using a different miner.

The issue is strange though, it only seems to happen with spminer if I am running a p2pool on the same network? I tried connecting to hashalot as well and ended up with the same high ping after a while.

If I use SPminer without p2pool running on the same network there is no issue, I am so confused?

Setup is p2pool and one miner on one machine, then another miner on a different machine, pointing to the local p2pool.

The same setup running with VHM instead works with no issues.

Maybe I will try moving the pool to a different network, or try with miningcore instead.

The ping is not high, it's the program that display incorrect results.. Will try to fix it in the next release

i have the same issue too i suspect the default intensity of the miner is either too high or the miner itself is unstable making the entire system unstable & causing high ping'd submitted shares,

for example i can run the web browser for a quick search while mining with any miner except SPminer which behaves as if it is very taxing on the hardware even by itself

because of this & with less hashrate i make more with VerthashMiner

Amd or Nvidia? Whats the specs on the rig. Wich pool. Are you dual mining with zil? Wich version of the spminer?. Whats your launch config? Whats the corclock, memory clock and tdp of your cards? Driver version?

-AMD,7 old Gen 1 & 2 GCN cards
-i hopped on all vertcoin pools same result
-i'm not dual mining
-i tried all spminer releases same result
-my rig (an 1150 platform) can mine Primecoin & Turtlecoin just fine,two of the hottest most stressful algos out there
-as i said VerthashMiner works fine too
-the Driver is 18.6.1
-Ram 8 GB
 

just using the basic ....SPMiner -o stratum+tcp://xxxxx -u xxxxxx -p x --verthash-data verthash.dat --all-cl-devices

-AMD,7 old Gen 1 & 2 GCN cards

The good old 7970 and rx 280. The 7970 is from 2013. It might be that the default intensies are too high for this card, so in the next version I have fixed the -i parameter. I don't use these cards anymore so cannot test it. But I will run some pool test on my rx 570/580 cards.

The faster eth miner in this case is not that much important ( unless its really faster and its a different story).
Its more important to minimize the switch time between VTC and ZIL.
So, for the 4GB card, it means to create the Zil dag in memory without loosing to much in speed during VTC time but being ready when zil time comes.

Fee problems(the fee is mined in the first hour of mining):

mine 1 hour and quit: fee 12%
mine 2 hours and quit: fee 6%
mine 3 hours and quit: fee 3%
mine 4 hours and quit: fee 1.5%
mine 12 hours and quit: fee 1%
...

So if your rig is unstable and crash, restart every hour, 12% fee...


Gpu search high intensity problems

1. Searching 500 000 solutions in a low difficulty. 17 solutions found. spminer will only report 2 of them.
2. Searching 500 000 solutions and the pool change difficulty and reject your work.(stale share) you loose 500khash
3. Searching 500 000 solutions and the pool change block and reject your work. you loose 500khash
4. Searching 500 000 solutions and the pool restart your work. you loose 500khash (nicehash, zergpool and other multipools does this all the time)
5. Searching 500 000 solutions and the pool have a new job. you loose 500khash
6. Searching 500 000 solutions instead of 10 000 require more gpu memory and more power. Make sure that your cards don't trottle and and feed them enough power.

Spminer is faster in finding blocks.
 www.miningpoolhub.com and www.hashalot.net rewards the blockfinders and doesn't trow away the work in 2-5 that get rejected on other pools. As a miner you want to get payed for all your work.

Mining on a fixed low difficulty will hurt pool performance because solutions are skipped.

Couple issues with SP4.

Doesn't work with R9 280(x)'s anymore. Crashes the driver as soon as they start up. They work fine with SP3.

Insane lag a few minutes into mining on any of my systems.

I have been using SP3 for about a month now because of these issues.

i have the same problem with GCN 1 & 2 i told SP about it,a few minutes into mining it starts submitting shares with a high ping due to lag, in my case even SP3 lags, what driver version are you using ?

I use the newest drivers. I have a Radeon Pro Duo in 4 different systems because none of the miners work right if I put 2 of them in 1 system. So I can install either the Pro drivers or the Adrenaline drivers. It doesn't make any difference however with Sp4.

WHAT? WHY ALL MINING FEE IN THE FIRST HOUR AND WHY I CAN'T FIND THAT INFO ON GITHUB OR IN THE START POST? At this point, all miner must go out! Ridiculous!!!!
What is when i mine 13 hours? Start again with 12%? So only 1% when we mining 12 hours? Mining longer more fee, mining less more fee? Makes absolutely no sense.

By the way spminer give me the same perfomance as the original verthash miner and make more problems as verthash miner.

Try srbminer 0.7.5, i think it will work with your old cards or the original verthash miner.

Spminer #5

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

- Fixed the pool latency bug (high ping)
- Fixed the intensity option for amd cards (removed the cuda dependency)
- improved the fee code to mine a few seconds every hour. ~1%
- improved the Zilliqa switch so switch faster when zil mining is ended.

Note that this miner is tuned for miningpoolhub.com and hashalot.net. You get around +10% more coins if you mine on these pools. Dual mine zilliqa with zilminer and proper launchconfig for another +15% profit

yes it could be, when you drop the next release with the fix i'll tinker around with the -i command & see,
thank you

#5 has been released with a fixed -i parameter

Doesn't work with R9 280(x)'s anymore. Crashes the driver as soon as they start up. They work fine with SP3.

try #5 with the -i parameter

Insane lag a few minutes into mining on any of my systems.

this bug has been fixed in #5

WHAT? WHY ALL MINING FEE IN THE FIRST HOUR

It doesn't really matter when the fee is calculated as long as you mine for a long time. But in#5 the miner is mining the fee a few seconds every hour. ~1%

EDIT: zil switch works very well, start time is perfect, but maybe the delay is a little too long at the end of pow window? Not much, but a bit.

#5 has a shorter delay than #4 for a smoother switching and longer verthash mining period.

So, for the 4GB card, it means to create the Zil dag in memory without loosing to much in speed during VTC time but being ready when zil time comes.

Ethereum algo integration is still in progress. spminer #5 loads the dag in 1 second per card in the rig for smooth zilswitching.(you need 8gb memory in the rig) zilminer already have the buffer cached.

That's good and so is the new way the fee is mined. However, I still have to use Sp3 because sp4/sp5 crash my Radeon R9 280(x)s and R9 290. Plus it's a about 6kH/s faster for each of my 14gpus than either Sp4 or Sp5.

Sorry I was mining another coin. I just tried SPminer #5 cuda 10 version and hashrate is reduced from 375KH to 245KH on each card.

Please restore the hashrate, I don't want to use SPminer #4 with the old dev fee system.
