ETH mining motherboard

[whoisthis]

i've got 6 RTX 3070s and looking for a motherboard and cpu.
could i get some recommendation on which cheap new motherboard and cpu to get right now in the market?
i bought used motherboard and cpu on ebay for couple of bucks and i don't get any power. They are supposedly refurbished.
I might just buy new ones if any available in the market.

Pretty much any ATX motherboard will have 4-5 useable PCIX slots but to support 6 you are going to have to look around a bit more and or consider one of the "mining" variants.
While not in any way new I have had great luck with my ASROCK H110 Pro BTC+ which supports like 11 or 12 cards at once. Pretty much the only requirement you are looking for is the number of PCI slots on the motherboard. Both x1 and full size slots will work for risers which you will need if you want to fit as many cards as you can on the given board. Other than the number of PCIX slots you dont' need a lot of CPU power for mining so something cheap that runs a plain jane Pentium chip will work fine and 8GB of ram is also plenty for most mining setups. If you are looking to keep costs down then check out the used market. Even something 6+ years old can be a good mining board as the speed of the CPU is not really important so just look around for boards that have more PCIX slots.

You can generally use an m.2 slot for PCIE as well with adapters such as these if you need an additional slot or two: https://www.ebay.com/itm/203314460170?hash=item2f567c760a:g:T2QAAOSwd2xgWVzi

I like getting old x470 boards for $50 / each or so. I generally go for ryzen CPUs but you could throw in something like an AMD Athlon 200GE for and additional $80 and have a pretty cheap combo.

There's some cheap server motherboards as well and a lot of the older 45W intel CPUs are about $4-8 / pair. The old ram is cheap as well. I bought some of these but ran into trouble with OS compatibility though so keep that in mind (they should run windows server & some linux distros/kernels, but not the version of linux that hiveos uses).

Had great luck with this AsRock board as well.

The ryzen systems look temptimg do they run 6 gpus happily?

Just a note on the x8dte, they are really only good for 5 gpus and as mentioned os compatibility may be a issue with mining os.

Just the motherboard is $50 on eBay.

For the most post I don't have issues. It's nice having a bunch more options as well in case you need to tweak things. I have had some motherboards though where they work fine with 6+ GPUs on one rig and the exact same model work with only up to 5 GPUs in another rig. Probably has to do with the pcie lane speeds but the less tweaking you have to do the better, or if you have to fix a bunch of settings, it's at least nice if you're buying the same board everytime and can make a simple checklist for what to do on setup.
