2xAshrock H81 btc pro VS 1xAshrosk H110 btc pro ?

[Cop999]

Who can advise that it is better to take two Ashrock H81 btc pro or one Ashrosk H110 btc pro?

I think that the money will be somewhere close, although for the H81 it is necessary to take dual hardware (2 motherboards, 2 processors, 2 memory),
But for H110 one power supply unit is also worth a lot.

In general, what option is  better.

I await your comments and advice.

If you know how to run linux, get the second one. Windows only lets you do something like 6amd+6nvidia and have to split the mining softwares.

You can just get two big psus or three smaller psus. It saves you a lot

That can be a tough choice.

Even if you go for one H110 option, you may still need two power supplies. (If you're using enough cards to exceed the capacity of one H81 board, one PSU might not be enough, depending on the exact number and type of cards.)

Also consider the possibility of failures. With one rig, if the motherboard/CPU/RAM/etc. fails, all of your GPUs are down until you have a suitable replacement. On the other hand, running 2 rigs may create more points of failure (yielding greater chances of A component malfunctioning), although the two systems will be independent.

With recent cards & drivers, Windows 10 can support 8 AMD and 8 Nvidia cards. Most users have to do quite a bit of troubleshooting to make that happen, however.

Personally, I would use 2 H81 motherboards for two separate rigs.

Yes, good.  You right about possibility of failure. Low chance have two rig down for part same time, but with one motherboard all mining will stop.

But if look in future, Ashrock H81 btc pro use DDR3 memory card, Ashrock H110 btc pro DDR4 memory card. May be better to buy moterboard with DDR4, I means with new technology? Or for mining no problem witch type of memory use?

I looked at the H110 board as well, but decided against it. The reasons were similar to those posted above, with the main one being if I lose that rig I lose 13 GPUs worth of mining for a period of time instead of 6 or 7. Also the need for two or three PSUs' depending on the cards you use.

The price of the H110 right now seems to be about what 2 H81's would cost, maybe a bit more. So sure you have the expense of an extra CPU and memory stick, maybe $60-$70, but other than that everything will be much the same, just with extra headaches.

For me, 6-7 GPU rigs seem to be the sweet-spot and I will continue to build these for now. If the price of the H110 would come down some to make it a bit more competitive with the 7 slot mobos, I might consider running it with a 2000 Watt server PSU and only run maybe 10 cards.

If you want to be able to use the mining board for a general desktop in the future, then DDR4 may be desirable, but I don't think it should be a deal-breaker. Although the DDR4 standard did bring some performance increases over DDR3, the real world gains for desktop performance aren't a huge deal. The big differences have mostly been about improving power efficiency and making it easier to produce dense RAM sticks.

I would go for the AsRock H110 BTC PRO together with 2 1000-1200 watt PSU-s. It will run fine and Windows lately is offering updates to support more than 8 GPU-s which was the limit Windows had only a few weeks before. I have seen this board running 10 cards without problems in Windows, so this board is not Linux only territory anymore. I am sure in other upcoming updates Windows will add support for more cards making this board running the maximum of 12 or 13 cards.
