seems there has already been a posting here quite detailed and the person seems mention using 2 cables 1xmini6pin to 1x8pin on EVGA powerlink
maybe this is safer?

Don't matter, the power that the backplane can provide by the PCIe AUX connectors to the PowerLink won't be changed using different cables.
@tsialex, would it be enough then if EVGA Powerlink used with 2xmini6pin to 1x8pin cable only to get maximum out of Powerlink on the MacPro 5,1?
such one here https://www.ebay.it/itm/253881653328
or is it better to use 2xmini6pin to 2x6-or-8-pin for use on Mac Pro?
like two of such those https://www.ebay.it/itm/184964732152?hash=item2b10c1d4f8:g:x7MAAOSwQCxg~88o

Dude, Powerlink is designed specifically to provide optimal output from whatever you throw at it. But you will not magically create "more current" when you split the 2x6 to 2x8.
If you hook up 2x6 to 2x8 you theoretically end up with exactly the same current as you'd have with 2x6 to 1x8. You will, though, create losses on connectors and overall a cable mess. Keep it simple. A single 2x6 to 1x8 is what you will use, Powerlink will do the rest and equalize the current to the actual GPU connectors as needed.
I've already told you what to do back with post #900.
The best way to power a PowerLink is connecting two standard 6-pin mini PCIe to 6-pin PCIe cables to it, but now we are nitpicking looking wire resistance and other minor factors, like the 8-pin to 2-mini PCIe 6-pin having less ground wires and etc.
By the way, from an electrical point of view, 6-pin to 8-pin mini PCIe is an abomination that shouldn't exist.
thanks, i have some several cable setup available:
1. 2 cables mini-6-pin to 6-pin
2. 1 cable dual-mini-6-pin to 6-or-8-pin
3. 1 cable mini-6-pin to 6-pin + 1 cable mini-6-pin to 8-pin
so i guess, all 3 options are valid for the powerlink to function properly.
sorry for my insistence, but this powerlink came bare of any manual, and i am not used to power graphics cards with extra cables.
another question:
now that i have Opencore installed, what is the proper way to load the graphics driver for Lexa based WX 2100 Radeon Pro?
can i just add a folder Kext, in EFI where OC is located, put the kext in and re-bless the thing?

Install with 2 mini PCIe 6-pin to 6-pin PCIe.
Please don't ask this again, I've already explained this to you.
Lexa GPUs are not supported by macOS, you can't do anything about it. Even if you spoof a supported one won't make it work correctly.
sorry for bothering: took a Geekbench OpenCL-test for RX 580 (Pulse) 8 GB on MacOS 10.14.6 and the score was rather low with 39.000+ points;
a Radeon rX 570 Nitro 4GB the same test but on MacOS 10.13.+ would yield 42.000+points.
My question: is the card RX580 lower in test because it is loaded via OpenCore or what could be the reason?
the same card in Monterey 12.6 would get even lower around 26000+ points.
The Pulse RX 580 got flashed by Professional seller, did not test the card before; the Nitro card was unflashed PC-Version. thanks.

That's peculiar, I just ran it on my RX 580 to see if I could replicate (with everything open, didn't bother closing any of my browsers, Outlook...etc) and got >44,000:

If it helps, mine isn't flashed, it's just a standard PC card. I keep my old GTX 680 around for if I need a boot screen.
the graphics card is very silent, which is great, but i was hoping that it would yield bit better for Monterey, which is a bit slow on the MacPro5,1 even with faster graphics card.
Metal is 29000 and OpenCL 27000+ for MacOS 12.6
Only real upgrade-option for DualBooting Mojave and Monterey seems to RX Vega 56/64 or Frontier, so i think it might be going for one in the next year, hopefully.

Did you get this card new or used? Used ones could have been used in mining, and often miners flash a bios with slower clocks.
yes, used, but nevermind, it is working fine, was just wondering.
even that i could have gotten an rx570 with a rx580 bios, but thats maybe farfetched, dont know if such a thing is possible.
guess, the rx vega 56 wont be such a silent card, after all.

I mean, given the other results shared here, I think something's up with your setup. I find Monterey is the best performing OS I've had on this box.
I just ran the Metal benchmark, and, streaming music to my stereo via iTunes, 56 Chrome tabs open, 23 Firefox tabs open, 8 Brave tabs open, Outlook, Whatsapp, Teams, Apple Maps, Parallels (RDP), Word, Messenger and several finder windows open I still managed to get:
alright, thanks, will check,
hat installed via OCLP installer, and used MartinLO Package0.8, but afterwards i ran severel times RefindPLUS installer, maybe it did mess up something, i don#t know, Monterey runs fine, is just bit slow, even with the RX580 8GB; i have an NVME 970 Evo Plus and it is full speed, so maybe a clean install could bring clarity, but for now, im ok.
System-RAM is only 8GB, so maybe this is slowing it down a bit, but it shouldnt.
EDIT: well,well,well, speaking of the "devil" ... just got this "image" on my desktop

Ewww, well, that's possibly a hint, lol.
I've considered bumping up to the 96GB limit that we can apparently do, but it runs very well with the 32GB, so motivation is lacking
Mine is a clean OCLP install, nothing else. Dual boot with Windows 10, both on their own SATA Kingston KC600 512GB SSD's.
and update to the above post with low benchmark in monterey;
as i got this news update in youtube today, decided, to test it out, and it actually brought back the GPU benchmarks to "normal" eg. levels like in Mojave; hope this is also useful, in real-life
decided to re-install, but it seems that it does just need to edit this setting in OCLP;
don't know if this is easily available for other who dont use OCLP Patcher,

Again this video - try anything that requires SMBIOS spoofing, like HEVC video encoding or Safari DRM, for example.and update to the above post with low benchmark in monterey;

Everything that requires SMBIOS spoofing stops working, I really don't understand why someone makes a video that claims 30% more performance if everything that is hardware accelerated stops working and the video doesn't make the adverse effects crystal clear - maybe he didn't even bothered to check anything but benchmarks.
The phrase "Optimizing to run benchmarks doesn't make your workflows complete faster, usually makes it slower" fits like a glove here.

luckily , you could help out , so the "damage" is minor,
my OC is still abit a mess (no regular mac user anymore)
have several OC on my computer, so i could boot into old configuration without changing anything,
and then the benchmark is again around 27000, but video accelleration is back, so most probably will have to re-install and tidy-up.
