Thanks Lolliedieb, working great as usual. I'm still mining away on HEPTA with my vega/rx570 rig. I have a request, and not sure if it's possible, but I notice that my pool rated efficiency goes down as I start undervolting the cards (I presume from bad blocks I'm sending in?). Is there any way we can get some sort of percentage of valid results from your internal checks for each of the cards that you display sol/s on? Something I could use to tell if I've undervolted too far on one card or if any particular card is returning more bad blocks than another? Is that even possible?

Just a thought. Otherwise, I'm always happy to see any performance improvement that you could gain from future patches!

Thanks,
Cyg

edit: Also, would there be any benefit to adding a CPU option to the miner? I'm not sure how many sol/s we could expect from it but I feel like I need the cpu on this rig working towards something instead of sitting idle... Tongue

Theoretically the miner can run on CPU - currently this is disabled (it only sees GPU devices), but for any CPU where there is an OpenCL driver it could run. Maybe I enable this experimentally.
As for the checks: in release version I disable all checks and pray for the algorithm to work correctly, since else CPU load would be very high. There are rare cases where flipping memory bits can invalidate a result or make the miner stuck, but also rare cases in which the miner can produce a faulty share. I will try to reduce this cases in new code.

Thanks Lolliedieb for the great work, I would like to request for BitcoinRm. This new coin is using Equihash 144_5 algo. Looking forward for your good news. Thanks in advance.

Thanks for mentioning it, I will add it in next version.

lolminer results 0.43 with my undervoltaged amd cards ->> BTG

Vega 64 LC (XFX) = 35 sol/s (PWR= -30% / RAM = 1060MHz) (2 pieces = 510W)
RX480 (XFX black)= 18 sol/s (CLK=1160 P-Stage=4) (4 pieces = 490W)
fury (x -> **) = 25 sol/s (** 2 x pro duo = 4 x fury = 100 sol/s @ 670W >> undervoltage 950 MHz/-25%/1,05V)

not profitable, all together need 1670 Watts (2x Vega 64 LC + 4x RX480 + 2x Radeo Pro Duo =>> 270 sol/s).

For the Vega it would make sense reducing core a bit, but keep memory up. Then undervolt the core, so the card does not throttle clocks due to running into power target. Similar for the RX series. I heard someone to have about 19 sol/s @ 95W on 480 - with some uv that should be possible and would look much better.

By the way current status:
First of the 6 new GPU codes went today from development to testing - but I will not tell you which Grin

Well its one of the Nvidia codes. Later today then start of the corresponding AMD codes.
Further this week SafeCash will rebrand to Genesis (GENX) including new personalization string. I plan to update lolMiner at the end of the week with the new strings (and BitcoinRm) plus some bug fixes (this command line stuff with = sign and one sources of 0 sol/s but for 192/7 on AMD).
See you then and keep posting your wishes and suggestions
