We ordered some to pair with our GTX 1080 Ti models (and a few Vegas). The plan is to have 6 Acorn 215+ paired with 6 GTX 1080 Ti on a ASUS Prime 370-A motherboard, using the ASUS Hyper x6 addon card for 4 Acorns (since that motherboard does support Bifurcation) and 2 Acorns on the M.2 slots on the motherboard itself. If need be we can spread them out over more motherboards since we currently have more motherboards then GPUs on hand.
How would that work with only 3 x16 slots 8/8/4 and 4 x1 slots (which to my understanding are useless for the acorn)?
Also, what is everyone else intending to use for a mobo? I can't seem to find any affordable options with more than 3 x16 slots and 2 M2 slots, one of which is usually in the way of a x16 slot.
I'm not jumping in due lack of afforable mobo options too. Waiting for an epyc mobo with 7x pcie 16x slots and 3x m2 slots for $300 - $400.
Imo Antminer z9 mini for $650 with coupons is a better place to invest than 2 acorns right now.
I was going to type something up, but this quote from discord already says everything I was going to.
"but anyways if it's a 2.0 riser max 4gpu to 1 acorn density, if it's 3.0 link speed then it's up to 2 gpu to 1 acorn density. But the proper balance for a particular algo means doing the math with the numbers on the chart
if you are on a full x4 connection then you can go up to 1:1 density
or more if the gpu on x8 or w/e
1:2"
Also, the Z370 chipset has up to 40 PCIe lanes, not 16.
The drop from PCIE 2.0 x4 to PCIE 3.0 x 1 is reported as not being too bad, but in any case we will be testing it to see. If the numbers are too much worse we have other motherboards to spread out our 1080 Ti GPUs with 1 to 1 Acorns ratio. I got a Threadripper 1950X recently for some personal workstation use, so we may play around with that too (some really nice possibilities there with 64 PCIE lanes for Acorns and GPUs).
