wow nice failure description - in most such cases the failure is sitting in front of the monitor.

Hi,

I am looking for the commands to use in WildRig miner in HiveOS.
I realized from the previous post that to enable certain GPUs mining, we can use -d 0,1,2,5.

Could someone please share the rest of the commands such as memory clock, core clock offset, power limit, fan etc?

Intel CPU with iGPU usually show the same behaviour. It uses the iGPU with an attached display and when it senses a dGPU with a display it will switch to that but you will probably still see the iGPU in device manager. This is from memory as I have not used and Intel for a long time.

Maybe power management got smarter and can detect if/when the iGPU is not being used. It shouldn't be difficult for zen4 CPUs because the
iGPU is only to "light up a display" according to AMD CEO. Just speculating.

It's not an ASRock thing. All suffer from the introduction of AM5 socket and chips. Keep an eye out for BIOS updates the next couple of months as they will come as it is a brand new platform.

Changing the primary display adapter setting in the BIOS to external GPU might do it.

Info about GCC support for znver4...

https://www.phoronix.com/news/AMD-Zen-4-Znver4-GCC-Enable


The current advice for compiling is to use znver3 and add the AVX512 extensions manually. For the binary Windows builds avx512-sha-vaes will provide near optimum performance.

All is well. cpuminer-opt development is winding down, running out of ideas. I have one more release coming with some new optimizations
and propagating existing optimizations to another algo or 2 that doesn't yet have ASICs. After that I don't know.

If you want to talk, send me an email or PM.

----------

Before the next release I'd still like some data for zen4 in case the builds need to be tweaked.

It is physically !!! impossible for a smaller node process to be less efficient ...

As a miner you should know such a simple and verifiable fact.

Interesting but it seems focussed on profiability which we all know is bad news. Most of those algos are a waste of time.
I was hoping for comparisons of AVX512 vs AVX2. Is that a 7950 or 7900? Some of the results are confusing.

avx512-sha-vaes build was not used on all algos, do you know why?

Can you provide the miner's startup messages showing the CPU features?

Edit: here's some data from my i9-9940x 14/24 core CPU for comparison of AVX512.

CPU-Z will do it on Windows.

Nice setup!

Some algos of interest for performance testing:

myg-gr, groestl: heavy VAES, some AVX512
allium: heavy AVX512, some VAES
skein2, blake2b, keccak, sha256t: pure AVX512
SHA is not used much because parallel Nway is always faster.

myr-gr uses some AVX2 with the AVX512 build, Groestl is pure VAES+AVX512.
sha256d is also pure AVX512 but the AVX2 version uses Pooler ASM code so it can't be used for comparison.

Thanks for the offer. I hope to get one before the end of the year.

The big addition to 7000 is AVX512 but I haven't found any specifics about what AVX512 extensions are included. VNNI is the only one I've seen
mentioned because it's for AI and AI Is hot right now, but of no use in cpuminer-opt. I assume DQ, BW & VL are included to be compatible with the
Intel Skylake-AVX-512 I use as a baseline reference.

The first thing would be to confirm the AVX512-SHA-VAES Windows build works on Ryzen 7000, Also confirm build options for GCC
(Linux or Windows) becaue zen4 isn't supported as of GCC-12. I've added some notes to the Wiki: https://github.com/JayDDee/cpuminer-opt/wiki/Compiling-from-source

I have read that Ryzen's implementation of AVX512 is "double pumped" which I assume is the same as the AVX2 implementation from zen1.
This will limit the gains of using larger vectors as was the case with Zen1 AVX2. The reason given this time was to reduce the clock penalty of
using larger vectors. It would be interesting to compare with and without AVX512. In some cases AVX2 may be faster.

The cache is larger so cache dependant algos may support more threads before cache overflow starts reducing performance.

Also keep a close eye on temperatures, I have read that zen4 is difficult to cool.

Edit: additional request from a Linux user: cat /pro/cpuinfo to get the list of AVX512 extensions.

Yes, but authors removed it from their OS. Why? They don't like easter egg inside the miner about khuylo Maybe I will provide custom package some day, but not in near future for sure.

as replied above,

i just wanna find a way to exhaust some of the hot air out of the apartment, simply opening windows doesnt help much !...
