I just bought msi z390-a pro
only 99 Euro - you can use a pentium gold for low cost.
2 pcie and 4 sli slots - so 6 gpu
I will run this with 6x 6600xt
Will built tomorrow - then the rig will be delivered.
I think thats one of the cheapest options
sure, but there are just a view. I prefer normal boards, cuz no one later on will buy probably a mining board. The h510 BTC is in stock, but it isnt rated well.
Don’t overlook ancient boards for used, cheap, and disposable. This is one of my most stable builds and … it is nearly a decade old and worthless to most:
Speculating you’ll have to disable a lot of the onboard functions with any of the LGA1200 H470/z490/x590 series mainstream boards to have enough PCI resources for a (6) GPU rig.
The board I posted above has SATA, most USB, extra LAN, etc., disabled or it only detects (5) GPUs.
Gigabyte Z390 D also works with 6 GPUs, but socket-1151 v2 CPUs like Celeron or Pentium are hard to get and very expensive. I was lucky to buy a Core i3-8100 for 50€ at auction.
