Colorful Intros H81A-BTC V20 Motherboard for Cryptocurrency Mining

Quite a few motherboard manufacturers are designing boards for crypto-currency mining rigs. The idea behind these boards is to serve up as many PCI-Express add-on card slots as possible, so miners can wire those slots out through risers, and drive way more than 7 GPU/ASIC cards. This makes for a better investment than building additional machines for more than 7 cards. Crypto-currency mining isn't bandwidth-heavy, and so even PCI-Express x1 provides sufficient connectivity for mining cards. The H81A-BTC V20 from Colorful is a socket LGA1150 motherboard, which takes in old "Haswell" and "Broadwell" CPUs, a pair of DDR3 memory modules, and puts out seven PCI-Express slots, of which one is x16, and the rest x1. The board draws power from 6-pin PCIe and 4-pin Molex, besides 8-pin EPS and 24-pin ATX, to cope with add-on cards that don't have their own power sources.

H81 and for toy money. Joke of the year. And also, isn't Broadwell only compatible with 9-series chipsets?

Not the old Broadwell release. And cryptocurrency really doesn't care what CPU it uses. The only thing you want is something dirt cheap with power delivery capabilities mobo wise, and this fits the bill. Probably using old parts they can't sell otherwise.

As long as they can't get trust able distributors that do not rip off their customers outside China(?Asia) it's pretty useless like with the Asrock, Biostar etc.

Cheapest one I can find is 110$, and the other Board vendors are >125-250$ currently.
Who is that intelligent to buy a board that should be around 50-60$?

For average 80-200$ you get a used Workstation for min. 4 GPU's
including:
- 750W-1000W Power supply,
- HDD,
- CPU
- Memory.
If you choose carefully the CPU is still good enough to mine some xmr.
If you are lucky there is a Quadro card inside that still get you some bucks.
If you are really lucky you get a workstation with 4G Decoding Option in Bios and 5-6 PCI express Slots.

Really weird seeing a DDR3 and Haswell board being released in 2017. Must be new old stock parts

The market for h81 is very large right now in cryptocurrency. I have talked with several people trying to get a hold of the biostar h81 board and they are going for over $200 anywhere you can find them.

I wonder why when literally every other chipset can do the same thing given enough PCI E slots

Because it says btc on it and they are known to work and they have 6 pcie slots.

They probably just had a surplus of h81 chipsets and used that since they were abundant

That and the processors are inexpensive

Its not very colorful...

Either way I wonder how long this cycle will last. I still have a cheap board with a bunch of slots I used for mining back in the day. But I am short on cards to really make it worthwhile anymore.

I guess toy money miners will accept everything.

Why do you dislike mining so much?

Because it drives up graphics card prices for real users (gamers), wastes electricity and sucks for the environment. Normally, I don't give a rat's ass about environment etc., but when millions of people do this, it's not a good thing.

Also, buying an used graphics card is a hell of a risk, I bought two used HD5870s when the last mining crazes were almost over, and the cards were pretty "raped" by mining.
