For Arch I have created a working PKGBUILD for gpuowl, based on the stable tag version. You can find it here: [URL="https://aur.archlinux.org/packages/gpuowl/"]https://aur.archlinux.org/packages/gpuowl/[/URL].

Nice, thank you! I hope others will find the package useful.

This time I had one from the first batch delivered, a RTX 3060 ti from Gigabyte Aorus Ti Master

Factory clock setting is 1800 MHz and 1400 Mhz memory, CPU-Z 1.94.8 reports 2010 MHz clock and 6800 MHz memory. Mfaktc reports 1800 MHz clock and 7000 MHz memory.

Under Windows using gpuowl v6.11-380:

Quick question: How much PCIe bandwidth does gpuOwl need if no monitor is connected? I found out that GPUs when used for mining cryptocurrencies, can work with PCIe x1 Gen 1. Is that the case for gpuOwl, too?

I found out that GPUs when used for mining cryptocurrencies, can work with PCIe x1 Gen 1. Is that the case for gpuOwl, too?[/QUOTE]My mining rig style systems say x1 to x16 extenders are fine, for gpuowl or mfaktc etc. There may be some performance loss during gpu-host transfers, but it's offset by better cooling and higher gpu count.
If you find a utility to easily look at PCIe traffic stats on Windows, please post a link.

Alas, Radeon Vii, on PCIe V2, x1 to x16 extender, and GPU-Z combo, does not display Bus interface load, although RTX2080Super does (note the 0% usage there, on PCIe x16 V1.1). On a GTX1080 in PCIe v2x16 direct, it's running 48% in 183M PRP. I don't think I have any PCIe v1.0 to test. Even the Core2 Duos and Quadro 4000 or 2000s are V1.1 or higher. I'm running gpuowl 6.x and 7.x on Radeons with a PCIe Gen1 setting in the motherboard BIOS, and getting within ~10% on Windows 10 of what others report getting for throughput on Linux.

After switching to Windows 10, I got gpuowl V6.11-380 to run on my ASRock Deskmini A300W, AMD A8-9600, 16GB DDR-4, SSD.

I tried multiple times to get ROCm to work in linux but it seems like I still have some learning to do before I can make that happen. After seeing the mprime performance of the AMD A8-9600, (max output 13 GHz-D/day while using 70W power) I shut down the computer and started looking for a Zen 2 series cpu to replace it. I got bored waiting for the cpu prices to come down and decided to try again with Windows 10. The iGPU works better than I thought it would. Mfakto results will be posted in the proper thread as well.

Moebius, here is your timing:

GpuOwl uses very very little PCIe bandwidth. I regularly run it over PCIe x1 Gen1 without significant slowdown.
