Sp-mod decred private 1 is doing 600mhash @1405 core. (750ti)1.7.4 opensource is doing 550 on the same card and clock. Both compiled with cuda 7.5.

looking forward to testing this and the coming updates

For all who keeps asking about ETH and mining try the miner from here since ccminer does not support it: https://bitcointalk.org/index.php?topic=1368785.0

Also have a look at Genoil's thread where you can get answers for it and how to use: http://forum.ethereum.org/discussion/2227/cuda-miner

You'll probably get more answers quicker. Don't forget to donate to Genoil for his work.

how to mine blake2s?

tpruvot's CPUMiner-multi has it implemented, though it says it is untested in the read me.

Anyone mining ETH on W10 getting any good hash, not sure if SP's miner solved the problem?

CCMINER DOES NOT MINE ETH--

Genoil's miner, a CUDA coded miner, mines ETH.  If you search CryptoMining-Blog.com, you will find the latest release.  Genoil and sp_ have collaborated, but the CUDA Ethminer is Genoil's.

Win 10 is reportedly bad for Ethminer performance on nVidia cards.  One miner keeps touting a specific nVidia driver for Ethminer and Win 10, but he may be trolling.

 I have no Win 10 rigs.       --scryptr

Alright, thanks buddy.

i mean with gpu, it's pointless with cpu if you don't have a cpu farm and none has it

I get 1405 Mh/s per 970 and 495 Mh/s per 750 Ti with 1.7.4 with OC. I have no idea how others get 550.

If I was mining Decred I might buy it but I'm not. Eth is much more profitable and uses about 15-20% less electricity.

bathrobehero    Try 64x not 86x you should get 512 mh/s.

Thanks, tried that and I figured it out that I can get close to 500 Mh/s (still not over, with OC) if I only run 1 card.
With more cards I assume I run into some kind of CPU bottleneck with a dualcore pentium even though it's only at about 27%.

Funny because I get ~ 515 per card oc to 1345 and have the same type of cpu...running a 6 750ti rig.
I forgot.... add this    --cpu-priority 3   if I go to  --cpu-priority 5  I can't connect to my rig.
I'm getting  3,100 mh/s total.

Sp what do you get at 1345 oc ?  I may contribute to your release.

@Sp with your private decred miner one of the card perform half,(5-6 card rigs)How possible to fix it? With tpruvot miner  no problem occurs.

[coinut]

having issues with your private decred miner sp

supanova

more rejects and more unstable on getwork
loads of rejects with stratum.. to the point that the worker gets disabled

tpruvot works fine with getwork

pool MN

about the same rejects as supa on getwork but lower reported hash
low rejects on stratum but reported hash rate always under reading. 3445mh/s local 2800mh/s pool side

back to tpruvots miner for now.

disappointed sp..


tried for many hours on pool Mn to get the hashrate to read the same as local, running one instance per worker then two and three.. no difference. also tried multiplying and dividing diff locally with no joy. hashrate barely ever touching 3000mh/s.

My fork was based on 1.7.3 wich have issues. I need to refork 1.7.4 and make a new build

but you sold it and knew it had issues? LOLOL money hungry asshole once again.

I have only modded the cuda code. My subscribers will get updates. Fixes where submitted in the stratum/c++ code afterwards(github)

which algo work best for 750ti cards? Can you please tell us the hashes a 750ti can make with your miner for vanilla and decred?

On a normalised hashrate basis lyra2v2 performs better than most other algos compared to other maxwell cards.
That doesn't mean it's more profitable than other algos, it's just more profitable than other cards when mining lyra2v2.
I haven't compared vanilla or decred.

Yeah, similar issues with SP's private decred. I'm getting 100% accept with stratum. Getwork is still buggy, just like with Tpruvots.

Something I've been reading up, from the Suprnova thread on the Decred forums:

This is a confirmed bug in cgminer on windows. It affects all pools. This flags seem to help:

--no-submit-stale --scan-time 2 --queue 0

Unknown-work means you are sending work back to the pool that was never requested - thats why it gets rejected, on windows cgminer seems to wrong calculation of the hash sometimes which results in this behavior.

It will probably get fixed in one of the future releases, or simply try the flags above.

However, CCminer doesn't support any of the above options besides 'scan time', so you can't tweak the other two options.


Putting all of the issues with accepted shares aside. Does anyone have problems with the miner speed not matching pool speed? Tpruvot and SP's miner show 25% faster hashrate then the pool is showing, even with close to 100% accepted shares. The only place I've seen the pool speed show up correctly is yiimp. MNpool also has the same speed issue. This is averaged over about 24hours so it's not a outlier.


SP, not sure if you saw cryptominingblog today, but they were talking about improving performance by using compute 3.5, at least it works that way with Blake-14, have you tried it with Decred? I assume it may yield similar results as Decred also uses Blake.
