Any risers which do PCI Express with more lanes?

Agreed getting a known working one is far better than getting one with pretty pictures

I think everything has slowed down to the point that I will have time to test the board tomorrow.  If it appears to be working I will be shipping it to Peter.

I have given in and will be

I have given in and will be buying a 1080Ti Nvidia shortly.  I hate Nvidias, their DP is shit, and they cost way more to buy.  But GPUGrid and Sheepit won't use AMD.

Apparently writing code for Nvidia is easier and has more help from others than writing code for AMD is.

The last gtx 1080 ti I bought was significantly cheaper than the last rtx 3080 ti I bought.  :)

Indeed, here a 3080Ti is 4x the price but only 3x as fast.

Shipped.  It is now up to Peter to see if he can really utilize 8 more ports either on his mining MB.  Or some other MB.  This card does not use drivers.  So the real limits are what the MB bios will "allow".  I look forward to additional conversations.

Obtw. Peter if your mining MB won't process on other projects you can always come "home" to e@h which does welcome radeon gpus.

My mining motherboard only

My mining motherboard only has 1 lane ports.  Your card wouldn't help there.  Your card is so I can put 8 GPUs on a fast CPU machine like my Ryzen 3900X.  The mining machine only has a little four core i3.  Although each core is 2/3rds of the speed of a Ryzen core, there aren't many of them.  I can always up the CPU in that another day, but Intel chips are overpriced.  I just wanted lots of ports.

I've got all my Radeons (the Tahitis and the Fury, not the old slow Baffin) doing Folding@Home, since I think we need more cancer cures.  My neighbour's wife died of throat cancer, thankfully for her quite quickly, but her husband still hasn't got over it after over a year.  They were together for over 50 years.  Folding uses a fair bit of data transfer between host and GPU, so it needs either your card or the mining machine.  Once I fix all the currently busted cards, I could have up to 13 GPUs, plus I plan to get a Nvidia soon for GPUGrid and Sheepit.  So 14 GPUs is a possibility, with more as I find the cash.  So I'll be using your card and the mining board.  Not just due to where to plug them, but who wants to go where.  For some unfathomable reason, some cards hate some CPUs and some cards hate being n the same machine as another.  So I need plenty of options.

What do you mean by MB Bios will allow?  I wasn't aware of a limit on the number of devices.  You just have to turn on above 4G decoding to increase the memory mapping space.

My experience is even with 4g

My experience is even with 4g enabled there is a limit to the number of video cards that a system will boot with.

The bios of a mining motherboard seems to be less fussy about that limit. You may be able to put the 8 port in the long slot of the mining MB.

Or you maybe limited to 5-6 gpus even with the 8 port card on your Ryzen system(s).

Plus you may have to switch to Linux if your os won't recognize all the cards.

Only trying it out and having a hard failure will show you what the limits of your bios/motherboard are.

I would research and budget for the most cores/threads your mining motherboard can support. I expect you will want to upgrade sooner or later. 

While there are mining success stories of mixing Nvidia and and video cards on the same system, I have had poor luck with it.

The drivers don't play well together.

The long slot I believe to

The long slot I believe to still be 1 lane.  The CPU wouldn't have enough lanes otherwise, the lanes come directly from the CPU.  I'm sure I looked up the spec on the manufacturer's website and confirmed this.  They could have made the MB so you got more lanes if you weren't using all the other slots (much like my normal gaming board changes from 16 lanes on the main slot to 8 if I put in two GPUs), but I don't think they did.

It's amazing, I just spent 10 minutes on Google and couldn't find anyone giving a hard limit on GPUs per motherboard.  Even miners don't bother going over 6-12 per machine, pathetic.  They're wasting money.  Silly excuses like power considerations, size of case etc.  They're clearly not very intelligent.  Power can be added easily, just use more power supplies.  Then they talk about the utter nonsense of the current you can take off a single 110V outlet.  Well use two then!  I'm using two 240V outlets here!  And size is easy when you have USB extenders which go up to 3 feet.

It's bad enough mixing two types of AMD together, nevermind Nvidia aswell.  Probably I'll stick to one model per PC.

The mining board's CPU is rated at 4000 on cpubenchmark.net, A Ryzen 9 3900XT is 33000.  It will probably be fine.  I can easily see if it's limiting it by looking at CPU and GPU usage graphs in MSI Afterburner.  Even my antique 1500 rated CPUs can do 4 GPUs easily and still have half the CPU free for CPU tasks.  So this one should manage well over 12.
