REBTECH 8 GPU All-in-One Mining motherboard

[jims2321]

It would seem they blew thru their stock and rebuild (RMA) units once people start talking about this board.  My 2nd unit I got was an RMA unit as well.  I think a lot of the RMA's were people having issues getting Nvidia cards working and just sent them back.  So technically nothing wrong, just people who were frustrated. 

Now the question is are they getting more stock?   And when.

I have a problem with one of mine where the 4 bottom USB PCIe ports do not get recognized.  I have to ship it back to them for repairs.  Hopefully it is something simple they can repair since they have no more stock.  If they had more stock I would get more of these boards.  I asked them about the stock and they said probably in about 2-3 months.

Well, that sucks.  But I will wait and grab one more of them, for my 4GB/6GB rig.

Got my Rebtech 8gpu to work with windows, and nvidia, and the monitor

I'm new to the forum, so I'm still exploring all the tech stuff out there. I stumbled across this REBTECH 8GPU-MB motherboard and it looks like a great option for miners.

If you are a beginner, I would advise you to study a simpler and more inexpensive solution and you will not break this motherboard by incorrectly connecting the riser in the pci-e x1 connector

at $80 this is the perfect beginner kit for 12 GPU,and this motherboard has no problems with bios settings.

The REBTECH is simpler, it doesn't have PCIe_x1 slots, it uses USB connectors instead. There's no need for those flimsy PCIe adapter tabs.
I'd recommend a board that uses USB connectors for PCIe for a dedicated GPU mining rig, but one that can also accomodate a decent CPU for a hybrid rig.

On the other hand I wouldn't recommend a mining board for a newbie, I'd recommend a regular board with lots (up to 6) of PCIe slots. The newer boards
have fewer PCIe and more m.2 so I'd look for an m.2 to 4x PCIe adapter to support more GPUs if necessary.

If you lose interest in mining you can repurpose a regular motherboard. You can't do that with a dedicated mining board.

To expensive in my opinion. I pay mostly around 30 - 40€ for my mining boards. Mostly i buy normal consumer boards with enough pcie, but i also bought some Asus mining experts for 30€ or the asrock btc+ for 20€.
You have so many options - a good option is also to buy a normal board and expend the pcie slots with an pcie splitter - this works very well.

Chinese also produce nice and cheap products like this one:

Mainboard for 12 Cards connected over USB direct to the board, with an G3900 and 1 Riser for under 60€.

In my opinion every Octominer or how they all called is so absolutely overpriced - for what should i pay over 1300€ for a case with a cheap motherboard? If i build an "Octominer" by myself, i only pay 30% from what octominer want.
Octominer only as example and not to spread FUD.

Do the math mates and don't spend your cashback time for your parts with senseless expensive things.

Depends on how many cards and builds you are doing. I have 13 octominers I got a discount on them. been running them for 18 months no big issues.

but I have so many mobos and cases and gpus I lose track.

Selling some gpus on ebay I have 3 1080ti's left to sell.

The b75 motherboard does not have PCIe x1 slots, they use 12 USB ports. On new motherboards, there are problems with the settings for running 6 GPUs at the same time, and newcomers have a lot of problems with this. Regular PC MOBOs with lots (up to 6) of PCIe slots are expensive. So I wrote a proven and inexpensive solution.
