- Solve the quantity of port of PCI-E , 1 port can be extended to 4.
- Used plug-in design, without through the extension line could directly access the motherboard interface, and can be fixed to the Computer case.
- The main control board is powered directly by PCI-E interface, does not need an external power line, the main control board power no interference.
- Reduce the number of adapter card and adapter line, one line directly to the port, effectively reduce the loss of interface interference and wire.

I used these ones and all three worked, although at the moment I only have 3 gpu's on each one.

You also have two PCI Express slots, so pick up a PCI E splitter for one or both! You may run into issues if the motherboard doesn't have options like Above 4G Decoding or setting lane speed, but 3 should work fine.

You can try using PCI to PCIe riser or use one of these PCIe Extenders
If you're looking to expand further, you might want to look into a pcie expander
If it is looking like a problem with the board, I do have an older socket 1155 board, but it inly has 2 pcie slots. Does anyone here have experience with the pcie extender cards? If i could throw one or even two of these on that socket 1155 board, id be back in business.

Is that a Ubit 1 to 4 PCI-E Riser Extender?

I have 6 in total on various rigs running. I also run ubit risers, 170 of them to be exact and have had great luck.
Also I am no way affiliated with ubit just have had a good experience with their stuff.
yeah i got this one https://smile.amazon.com/gp/product/B073W9KCFC/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1 it's one of those Ubit ones from amazon. works w/ Windows (make sure to install one GPU at a time) and no-fuss set-up on HiveOS
Yeah, I had an older 4 slot gaming board which I turned into 7 with a PCIe splitter. It also worked on my Z270-A which expanded it to 12 slots. But splitters can be hit or miss, especially with older mobos.
Whatever you do, do NOT order from Cryptomined. Scammed out of $39 for a splitter that I paid for with crypto. Got the run around for months upon months. Should've just ordered through Amazon to begin with, which I just ended up doing.
The wiki links here for a list of appropriate motherboards if you're going to spend money on a new one.

Also, here's an interesting post I saved awhile back about a guy who used to buy a bunch of those cheap enterprise desktops and converted them into 3-4 gpu rigs. I guess this made more sense back when Z270s and mining experts were selling for $300.
I plan to buy some of these to expand these old motherboards I been using.

These old motherboards only allow 1 GPU, but with the adapter below, it can upgrade to 8 GPUs per motherboard.
 
PCI-E Riser Extender

There are cards like this, using a switch chip to allow connected multiple cards to a single slot:

Then you use the normal risers with it. I have not personally used this card tho.

my goal right now is to achieve highest machine/$ utilizing virtual machines , to do server>thin client feed efficiently you need hardware acceleration which means a gpu and that makes things complicated ...
im planning to do some experiments i can especially with these miinig stuff there are things like this which if they work would be a really nice solution....
im not an expert on pci lane allocation or pci passthrough but linus was able to get 8 individual cards off of a single pcie slot on his 6 editors 1 cpu system which doesnt line up with stuff ive been reading online on how iommu groups are the limiiting factor on gpu passthrough (maybe because he used acs override idk)...
Some sort of update: I believe at this point that the original reason for the death of the initial mainboard (ASUS M4A87TD EVO) was because of over-draw from the PCI-E x1 slot in which I plugged the linked PCI-E extender card.
And I'm thinking this is also the result of instability with the replacement board. So I'm switching to an ASRock BTC board with native x1 slots. There's a reason they require 4-pin molex to power the PCI-E slots, I guess.
Anyone else have experience with this problem? Or these PCI-E extender cards?
That card is a usb 3.0 controller card, it wont work with any pcie risers.
What you may need is more likely this:

Theoretically you could shove 20 cards on there as mining doesnt use a lot of bandwidth
