inexpensive motherboards for mining

[QuintLeo]

2 12 card rigs will tend to be a LITTLE less expensive than 4 6-card rigs - but if one rig goes down that's a LOT more lost income, and it's more of a pain to troubleshoot.

 They're also a bigger pain to set up in the first place, though if you can find a B250 Mining Expert MB at a reasonable price it reduces the pain somewhat due to the on-board multi-PS management.


 In my case, most of my rigs are 5-card because I already have the MB/CPU/RAM/HD from "left-over" FAH rigs and because I can configure them EASILY to run on about 6 amps of power per rig (which lets me put 2 rigs on a standard 15 amp US 117VAC circuit SAFELY).
 They're not the most OPTIMAL rigs possible, but I make up some of the difference by having the CPU mining Monero (or working Gridcoin for some I've not "converted" to full up riser-based mining rigs yet).

Is the Asus B250 the recommended motherboard of the 3 or so that do 12 gpu?  The problem I see with that is I want to use  a huge server supply like this https://www.ebay.com/itm/2200W-24Pin-Mining-Power-Supply-For-Antminer-ETH-ZEC-S7-S9-L3-D3-Miner-110-240V/332419018764?hash=item4d65b7b00c:g:V20AAOSwDEtaQciU

and it has 1 24 pin plug.  I suppose I can just get adapters for the 24 pin to make it two although 3 would be tough.

I"m still unsure if windows can actually see all 12 nvidia gpu's and whether the miners out there can work with 12 at a time.  Otherwise I might as well target 8 gpu boards.

GA-H110-D3A or better MSI Z270-A PRO for stability and not to have problem with recognize max gpu?

Yea I was going to go with the GA-H110 but figure if I can get more on a board, thats less components, less electric etc.

Any possible answer?

Cheap= Gigabyte H110-D3A (don't use mole on the board)

To set up first rig.

Must be easy. Later you build another rig of 12 or 19.
Keep it simple!

On MSI Z270-A PRO any special bios settings needed?

So I been thinking its more cost effective to run 2 boards with 12 gpus rather than 4 boards with 6gpus.

Can windows now handle 12 gpus from nvidia?  Is one specific 12gpu board better than the others?  I believe there is asus, asrock and biostar.

I was also thinking of using a server power supply or multiples with the pico power supply adapter to power everything.  Will these boards work with the pico adapter?  On parallel miner it seems most boards won't work off the pico supply adapter.

It's nothing really to think about, it's simple math.

Cost effective till you get a persistent issue, then you're doubling your downtime costs.

Then go for Asus mining expert and 12 Vega 64 and 7 1080ti.

Define cheap first. ..
