Submitted a possible improvement in lyra2v2. The same clocks as before. The rig is up 1MHASH in the displayed hash and less gpu-shutdowns.  |

The problem seems to be that when the CPU is working in the backround, the cards are producing very little.
|
|
|
|
|
When I am running in quiet mode and remove cpu verification, it runs at full speed.
|
|
|
|
But there seems to be a bug somewhere. The gpu is stopping quite often:  |
|
|

This is my numbers. I got the Windforce G1 970 up to 10MHASH The asus strix 750ti is also peaking over 5 With a light overclock. windows (x86 with the head at github without the intensity parameter set)  |

I submitted a bether launchconfig in the lyra2v2 algo. (commit 1103)
The gtx 750 (overclocked 1500 core) is up from 3650 to 4400 (source rednow)
The 750ti unchanged
The 970 up from 9200 to 9400 (windforce G1 standard clocks)
950, 960,980,980ti untested.
please build and test

as "kh" in 69 versions and give gtx960 gtx950 to Quark and Lyra2REv2.
p.s. Why in the first post is not to make a sign for speed and do not update it as an update miner?
I use English as my second language but I am unable to understand what your question is. The gtx960 can do around quark: 10,5 MHASH Lyra2REv2: ?? The gtx950 can do around quark: 8,4 MHASH Lyra2REv2: ?? The lyra hashrate is not tested on the 950 and the 960 |

You can set the opt_scantime with the '-s' switch. My default is 25. In the DJM34 version it is set to 60.
Does it help on the pool?
ccminer -s 60 -a lyra2v2 --benchmark.

Guys can you please provide config example for ccminer?
want to check how to use nicehash as primary and some other pool for backup, can't find such config example for ccminer.
Thanks.
You need external software to do this. Google "Miner Control" |

Then there is monacoin.
Monacoin just hardforked from scrypt to Lyra2v2. Pretty big in Japan.. |
|
|
|
around 1-1,1MHASH per 750ti
Thx sp Do you have this implemented in r69 ? I would like to get it to work ..for a test. yes. ccminer -a lyra2 --benchmark |

Seems like exist other profitable altcoin with lyra2rev2 algo?
Or it could be the bitcoin testnet wich is testing a new POW algorithm for the new fork of the bitcoin blockchain.  |

That is because the launch config is wrong for the 750. Check the lyra2v2 file and adjust the TPB and the intensity. else if (strstr(props.name, "750"))
{
intensity = 256 * 256 * 5;
tpb = 7;
}
As far as I understand I can change intensity with - i parameter without recompile. But it doesn't help, I tried. What is tpb? Can I change it without recompile? Threads per block. You need to recompile for each time you change it, but a change of values will speedup alot. See my edited post above... When you find the optimal values for your card, please post it and I will change it as the default setting.. The 750ti, and the 970 settings should be pretty good. (5-10% faster than DJM's version on the maxwell) The other models probobly need a different launch config. I haven't done it yet because lyra2v2 hasn't been profitable. And another thing.... My modded kernal is slower on linux and on older cards. (compute 3.0/3.5 Might not work). |

Wich card models? Wich operating system? I get 5-10% more hash on my rigs...
I've got 4200kh/s with djm's ccminer lyra and your release 60. But only 3740 with your r68 and r69 ((( gtx 750 1gb 1500/1600 That is because the launch config is wrong for the 750. Check the lyra2REv2 file and adjust the TPB and the intensity. else if (strstr(props.name, "750"))
{
intensity = 256 * 256 * 5;
tpb = 7;
}
TPB should be changed to something else. start with 1 recompile test, then 2, then 3 then.... 256 * 256 * 5 is the same as -X 5 run with -X 1, -X 2, -X 3 etc.. until you find the optimal solution. lyra2v2 is a semi memory algorithm. You need to find the optimal configuration for your card just like in scrypt mining. |

BTW the SP miner is still getting 10% less hash rate compared to DJM's original release. The power fluctuates a lot on the SP version compared to the DJM version.

Nicehash lyrav2 currently paying 2.6896btc ..Dropped to 0.50
Up to 0.9296 now.. https://www.nicehash.com/index.jsp?p=miners&a=14&l=0The top miner just switched from mining quark to lyra2v2 5,4 gigash all NVIDIA. I wonder if he is using the DJM-34 version or the sp-mod. This farm is making 3.274 BTC a day on this adress.. Pretty good.. No donations to the developers. If you release your faster lyra2v2 kernal djm34, he will upgrade and the profit will go away. Massive hashrate... equal to around 1300 750ti's @ 40watt (52,000 watt) But I think this company has some older compute cards. So the power usage is probobly twice as much as the competition. And all the rigs are linux based. |

is it all about the btc? ... or is there another motive? ... i would like ot know because if there is something WE can do about it - WE will ...
I have spent a year on this in my sparetime to learn how to program the GPU. Wolf0 has been modding kernals since 2013. He started opensource, and then found out he could make a living out of it and stopped sharing.. I will continue as before, release some small improvements to the public and keep some for myself. But one day I might quit my job as a C# programmer and do this fulltime.. then you are a fool (sorry to say...) and a big one for not realizing that your releasing model is flawed and will never get you any money... fun fact: satisfying your fan base goes in total opposite direction with making money ps: may-be I should start selling my kernel to you I could buy it, but my quark kernals are more profitable at the moment.  |
