Yes, riser-rig miners, ASRock has heard your complaints about the shortage of H81 (keep in mind that when Intel stops making a chipset, board makers CAN'T make more of the boards using that chipset once they run out of stock of that chipset) and has a MONSTER of a replacement/upgrade that is apparently fairly close to release.

 They DO need to figure out and fix whatever caused their demo to crash and burn first, though - perhaps add 1 or 2 more MOLEX to the MB for PCI-E slot power I'd guess....

 There is already a longish thread specifically about the H110 BTC Pro though....

Please write here feedback about 1-4 switches, it's very interest.
P.S. Where you are frome?

@dimka890 Thanks! I will try with a bunch of 1070's I have on the way.

@NotFuzzyWarm sry... wrong board. Maybe a mod can move the thread? Thanks!
Some chinese sellers say that switches does not work with Nvidia GPUs, but if you can test it will be good. Unfortunatly i don't have any nvidia cards.
P.S. I saw at aliexpress switches 1-> 4 PCI-E, there is no mention of nvidia cards, maybe 1-> 4 switch will be work fine

I'm waiting 1->4 and try.
And m2->pcie for 9 nvidia gpu on asus prime z270a

For 13 and more gpu remeber if you have problem with 1gpu -  you have problem with all gpu on rig

Sorry for english.

In this discussion: https://bitcointalksearch.org/topic/m.19319534

There is an example and a tiny bit of talk about a rig that controls 12 GPUs

The idea is that the builder uses PCIe Switches for 9 of the cards and the other three are on board:

Using common MSI Z270-A Pro + Celeron G3900 + 4GB RAM +3 x PCI-E Switches (9 GPU's connected to switch and 3 GPU direct to motherboard). Power Subsystem - two HP common slot PSU 1200W + 160W Pico PSU (for motherboard and switches)
Sorry for bad photo and my English)

Does anyone have experience making the CPU / bios / whatever to detect 12... or maybe 18 GPU's?

TIA!
12 gpu under linux works fine! Somewhere read that with 12+ gpu in single motherboard you'll have troubles, but i make rackmount frame for rig and there 12 gpu optimal. At next week want to test 4 PCI-E switches in old motherboard (HP Pro 3130)

Someone might know how-to but NOT here.  Roll Eyes This is Bitcoin-only and that means ASIC rigs only.
Now if you post in the ALTCOIN area https://bitcointalk.org/index.php?board=160.0 you might get answers.
