Topic: Phi2 miner for AMD (Read 4830 times)

Thanks to @crytotamer01 for introducing this opportunity.

thanks for the update

Beta5d release, much faster than beta5c, especially for 580.
https://github.com/fancyIX/sgminer-phi2-branch/releases/tag/5.6.1.3.b5d

Thanks for the info.
Their algorithm uses 4x4 lyra2, which has already been fully optimized by many miners and is much easier to optimize than 8x8 lyra2.
My miner is good at optimizing 8x8 lyra2, which is much harder, but may not be the best for 4x4 lyra2.

Nice work, getting closer!

Beta5b release:
https://github.com/fancyIX/sgminer-phi2-branch/releases/tag/5.6.1.3.b5b
Speed compare of release (beta5b) than previous release (beta5): 580 +25%, Vega56 +35% for phi2, and 580 -15%, Vega56 +35% for lyra2Z .

Beta5 release, about 30% faster:
https://github.com/fancyIX/sgminer-phi2-branch/releases/tag/5.6.1.3.b5

Lyra2z somewhat better than the old sgminer by djm34, but still has a way to go compared to mkxminer (https://bitcointalksearch.org/topic/mkxminer-fast-lyra2zlyra2rev2-miner-for-amd-gpu-zcoin-gincoin-vert-mona-2360168)
Hope you can do much better

Lyra2Z hashrate is 1620khs on my vega 56, on Ubuntu 18.04 with AMDGPU Pro PAL driver (https://support.amd.com/en-us/kb-articles/Pages/Radeon-Software-for-Linux-Release-Notes.aspx).
The hashrate on windows should be the same. I tried using newest driver.

Bro, please share the driver version and hash rate for your vega on Lyra2z.

all my cards have biosmod for eth, and mclock 2150 and cclock 1130

I mean the rate on your card is less than my card. I don't know why. My card has eth bios mod, but I am not sure if that's the reason. Does your card use default frequency? Did you bios mod?

hello @fancyIX you recommend me to change the biosmod eth of my cards to their original bios, or there is some specific configuration of watches that you recommend for your miner

My vega 56 has over 3300khs. My 580 has over 1800khs.

They are lower than I expected. My Sapphire nitro+ 580 has over 1800khs. It's bios mod for eth though.

And what AMD RX hashrates info you have  ) ? Can you share .

I don’t have 570 card. But I guess it’s around 1700 -1900 khs

What hashrate for phi2 expected for RX570 4GB ?

Beta4 release: https://github.com/fancyIX/sgminer-phi2-branch/releases/tag/5.6.1.3.b4. About 40% faster on my rx 580 and vega 56 cards. The speed is improved using pre-built binary kernels. They are only used if you use "-w 256". Please don't delete them otherwise new kernel will be compiled from source code and will be slower than those pre-built kernel. Please help test if interested.
