Thanks to AsRock we already have a sample of their new H110 Pro BTC+ crypto mining motherboard with 13 PCI-E slots for testing, so you can expect a review soon. The motherboard should start appearing on the market sometime later this month, so it is not yet available in the retail channel. It is a really interesting design and definitely something that AsRock had to do in order to “show muscle” after the competition in the crypto mining motherboard space started to heat up with shortages of the hugely popular AsRock H81 Pro BTC and other brands like Biostar announcing multiple new mining motherboards.

The AsRock H110 Pro BTC+ motherboard is pretty interesting with the 13 PCI Express slots available for use with video cards with the help of PCI-E extenders, but this also comes with some challenges. Initially we got information that the motherboard should work out of the box with 13 GPUs under Windows and Linux, and although that might be true indeed there seem to be some limitations. It seems that the 8x GPU limit is still a problem, however you should be able to run 8x AMD with 5x NVIDIA GPUs under Windows, but not all 13 from the same type out of the box (it could still be possible to overcome this limitation). For Linux users 13x GPUs do not seem to be a problem or at least thirteen ADM GPUs with the ethOS mining distribution.

Building a 13x GPU crypto mining rig could also bring some other challenges including problems with the power supply or to be more precise power supplies now that there are shortages and it is hard to source higher power models. Of course it depends on the type of video cards that you are using for your mining rig, but in general the new H110 Pro BTC+ crypto mining motherboard from AsRock seems to be more useful for builds that have mid-range GPUs and not high-end ones. Builds such as 13x AMD Radeon RX 470/480 or RX 570/580 that use single PCI-E power connector or Nvidia GTX 1060/1070 again with a single PCI-E power connector (sub-200W power usage) seem more reasonable.

Imagine what a challenge it will be if you want to build a mining rig with 13x Nvidia GTX 1080 Ti GPUs. At 250W for 100% TDP per card you are looking at 3250W of power required just for the video cards, there are simply not much options for dual PSU setups that can handle that, so it is more at least a three power supplies setup. In this configuration it is not just the power requirements, but also the number of PCI-E power connectors that you would need for the video cards. You would need 13x 8-pin PCI-E power connectors and 13x 6-pin PCI-E power connectors, then also 13x 4-pin Molex connectors for the PCI-E extenders. You also need to be careful not to overload any of the power lines of the power supplies by connecting too much components on to a single cable.

Not a lot of details about the upcoming AMD-based Crypto Mining GPUs from Sapphire Yet, though they have been already listed for pre-order over at Overclockers UK. There are four Sapphire Mining Edition video cards listed that are based on AMD’s Radeon RX 470 GPU with different video memory configurations, all of which are without external video connectors. There is also a single AMD Radeon RX 560 GPU also labeled as Mining Edition, though it is a bit different with a single DVI connector on the back, so it can be used for other things than just crypto mining. It is interesting to note that the Sapphire Mining Edition cards do come with 1 year warranty instead of the regular two or even 3 years warranty that Sapphire cards targeted at gamers usually have (depending on the market).

Sapphire Mining Editions cards:
– Sapphire Radeon RX 470 MINING Edition 8192MB GDDR5 Samsung 7 Gbps (11256-38-10G) – 25-28MH/s ETH
– Sapphire Radeon RX 470 MINING Edition 8192MB GDDR5 7 Gbps (11256-37-10G) – 24-27MH/s ETH
– Sapphire Radeon RX 470 MINING Edition 4096MB GDDR5 Samsung 7 Gbps (11256-36-10G) – 24-27 MH/s ETH
– Sapphire Radeon RX 470 MINING Edition 4096MB GDDR5 7 Gbps (11256-35-10G) – 23-26 MH/s ETH
– Sapphire Radeon RX 560 Pulse MINING Edition 4096MB (11267-11-10G) – 12-15 MH/s ETH

It is interesting to note that the store lists the type of memory on different models and what mining performance they will be able to offer for mining Ethereum (ETH). There are two values that apparently represent the stock and the modified BIOS result, though it is not yet clear if the dual BIOS comes with modified settings, or Sapphire has just left that part to the miners. Unfortunately the prices listed for pre-order are not making these very attractive alternative compared to the regular models, though with the current shortage miners may not care that much as long as there is stock of these new Mining Edition cards from Sapphire available.

Something that is important regarding the warranty of regular Sapphire GPUs that are not originally intended for mining, the website of the company has some additional terms listed about mining usage, here is a quote below.

Warranty may vary from Country/Region, the customer must verify directly with the SAPPHIRE Authorized Dealer/Reseller from where the product was purchased as to the specifics of Warranty provided.

Warranty also varies for products used in Industrial , Block chain and crypto currency mining applications and the customer must verify with the SAPPHIRE Authorized Dealer/Reseller from where the product was purchased for more information.

So make sure you check the warranty information of the seller whether you are buying regular gaming GPUs or any of the Mining Edition cards to make sure about the warranty period you get with each. We have already received reports form users that some retailers are selling GPUs without any mention about warranty getting void on their websites if they are being used for crypto mining and you get that told to you after you purchase the cards and have them shipped to you.

There is a new development version of the ethminer 0.11.0 (source) available that brings CUDA performance improvements especially optimized for GTX 1060 GPUs. People are reporting a couple of megahashes increase in the performance of GTX 1060 GPUs over what they are getting with the same settings from Claymore’s ETH miner, some slight, but less performance improvement is observed in GTX 1070. Unfortunately it seems that the performance optimizations submitted by David Li don’t do much good for GDDR5X GPUs like the GTX 1080 and GTX 1080 Ti.

Feel free to test it on your Nvidia mining GPUS and report what and if there is some improvement in the hashrate over your previous settings. If you do make sure you try different value for the --cuda-parallel-hash command line flag (default value is 4), but you can experiment with 1, 2 and 8 and see what works best for you. Again the highest benefits are apparently observed on GTX 1060 GPUs as the performance optimization is apparently targeted at them, though some other GPUs might still benefit a slight boost as well. You can download and try the Windows binary compiled from the latest source below.
