Where are you guys buying your motherboards? I can't seem to find anything in stock from the major online retailers. I'm looking for a 6 slot motherboard for rx 470's. The same goes for the GPU's. Do you just wait on a waiting list for stock to replenish or do you settle for a different model?

My first choice is clearly the ASRock H81 Pro BTC.

I'm looking at the ASRock AB350 Pro4 AM4 ATX AMD motherboard as an alternative to the sold out one, but I can't seem to find any confirmation that it supports 6 cards on linux.

Any advice?

IMHO, other alternatives are: Biostar TB250-BTC and TB350-BTC

the asrock is almost discontinued but there are good alternative check the asus prime z270-a and p version they can carry up to 8 gpu with proper tweak https://www.nicehash.com/index.jsp?p=news&id=155

These two are sold out


Ah yes, this looks like a good one. $40 more than what I had budgeted for my rigs, but may be worthwhile adding the extra cards there

I have asus prime z270-ar using 6 gpus not sure if i want to try 7th gpu.

I might ask for some help setting it up in a few days. Thanks for the reply.

I scaled down from 6 GPU to 5GPU rigs. Way more stable, cheaper parts (mobo + PSU) and also parts widely more available. Win win all over the place

I ordered a ASRock Fatal1ty Gaming Fatal1ty Z97X LGA 1150 board.

3 x16 and 3 x1 PCI-E slots. Researching I found multiple reports it works with 6 cards. $110 after rebate seems about the best deal for an in-stock board ATM.

6GPU has gigher density.

You can still buy the TB250 if you know where to look but for sure you will pay a premium from MSRP.

Im building all my rigs in MSI Z170A gamining 5 and a lot of RX470, im trying to nost waste much money. I cant find any asrock H81 on my city.

What GPU's did you use and where did you get them?  I'm having trouble finding the 570's I want.

I have asus prime z270-ar using 7 GPU's  470 4g 206.7 Mh/s

If you're from Europe i can sell you pro btc r2 boards.

Where are you from?

Waiting for parts is worse.

I use 570's and 580's. Got them from mindfactory.de

+1 and also what price for those boards and how much for shipping?

i am also kinda despair about the problems with parts. thinking about 5 x GPU setups also

Bought this one last week planning to build another rig

Be afraid.

Be very afraid.

 I just specified parts and priced out the first Intel-based rig I will have ever built since the Pentium 4 days (and THAT one-and-only rig was the first Intel rig I'd built since the Pentium MMX days, though I did end up with a pair of Pentium Pro systems at one point that quickly got upgraded to Athlon Thunderbird setups - the CASES were nice and cheap despite being "full systems").

 Up side - all PCI-E 3.x 16x ports for the GPUs, should help them when I send the rig Folding someday.
 Down side - I'm estimating half the performance out of the IGP on my Moo Wrapper/BOINC/RC5-72 work vs my usual AMD A10-7860 despite the Intel APU being almost the identical price.

 Tossup - MB + RAM + CPU ended up being almost identical cost to my usual choices, which I was a bit shocked at - Gigabyte has a sweet deal going for a NON-SALE price on the MB, quite a bit lower then the next-cheapest 3-card capable Intel motherboard I've seen for socket 1151, and DDR 4 at the low speeds has come down to where it's actually competative with DDR3 on pricing.


 Dunno if this is going to turn out to be ANOTHER one-shot setup - it all comes down to how well it does on Folding PPD vs my usual setups, though I expect it to be a tossup for mining as mining algos aren't generally PCI-E throughput-heavy like Folding is.


 I also noticed that the supplies of the RX 470/480 are pretty much all gone - and what's left is getting price gouged BADLY as AMD hasn't gotten RX 570/580 production up to full speed yet, thus THOSE cards are still going for a small premium to their intended "list" price range.
 I had ORIGINALLY intended to spec/price out a 4x card system using the Biostar Racing motherboard or a close equivilent, but no way am I going to try to space 4x 1070s (not Katanas as those have been "out of stock" longer than I've known about them) much less 1080s or 1080TIs that closely together.


 I still haven't decided between 2 x 1080 + 1 Gigabyte "ITX" 1070 or 2 x full-length 1070 plus the Gigabyte though.

Funny how back in 2013 there was a GPU shortage preventing difficulty from going higher.

Now the GPU manufacteurs learnt their lesson and over-supplied the market but the motherboard manufacteurs didn't and hashrate is capping because motherboards are sold out.

plenty of good motherboards  if you don't mind 4 card or 5 card rigs.

The over supply of GPU's sure didn't last long, they have been out of stock everywhere for about 2 weeks now.  June should bring new supply BUT everyone is so hungry to buy more they will be gone extremely fast then you gotta wait until july.

You can still swoop in on Nvidia gpu's though.

Honestly I like building 4 card rigs, I have a older mobo that I can get used and it is cheap + reliable.  It seems there are a lot of issues once you dive into 6 card rigs getting them to work and that is before you deal with functioning risers.
