AsRock H110 Pro BTC+ Mining Motherboard with 13 PCI-E Slots

31, May 2017

If you thought AsRock is getting behind in the game lately as far as GPU crypto mining motherboards go, well thing again… even though they haven’t had a new Pro BTC motherboard since the H81 Pro BTC they are not sleeping apparently and the recent shortages of that particular and popular model. At Computex 2017 the company has showcased an upcoming product that has caught the attention of the mining community, a motherboard with 13 PCI-Express slots for up to 13 video cards, connected via PCI-E extenders of course as the slots are pretty tightly fitted on the motherboard to retain a standard size.

The new motherboard is called Asrock H110 Pro BTC+ and is soon-to-be-launched (no exact launch date given yet)… it even has an M.2 slot onboard, though 14th card via M.2 to PCIe might be a bit too much to expect to work, but who knows. Other than the new chipset and the staggering 13 PCIe slots, the new motherboard seems to follow the design of the previous generation of Pro BTC boards, simplistic and cost effective. Of course the H110 chipset means that you would need to go to the newer Socket 1151 CPUs such as the Intel G3900 series of processors as well as the newer DDR4 memory.

We’ll probably have to wait a bit more for additional details such as the full specifications, pricing as well as release date and availability. You can expect the demand to be pretty high though, even considering that the demonstrated solution during Computex in Taipei, Taiwan apparently used Windows and had only 8 GPUs running (based on the available information), but all 13 should be available for use when the new motherboard hits the market hopefully soon (not yet sure if they will work under Windows though).

6x GPU Capable Mining Rig Motherboards are Disappearing

9, May 2017

With the recent craze with the price of Bitcoin as well as many altcoins rising up there is a huge wave of new GPU mining rigs as well as new crypto miners getting into the game. We already know that there are shortages of the very popular AsRock H81 Pro BTC motherboard for 6x GPUs for a couple of months now, but even more recent and more expensive motherboards with 150 and 250 series of Intel chipsets that support up to six video cards are also disappearing from the market. Next are probably the high-end gaming motherboards with 6x PCI-E slots that will work with six video cards if the trend continues. The Pro BTC motherboard from AsRock is hugely popular as it was designed for GPU mining and works out of the box, for other motherboards you need to usually do some tweaking of the settings and not all models have the right settings available in the BIOS or may have some specific issues. Another serious advantage of the Pro BTC series is the price, no extras not needed for mining means lower price point, though at the moment the demand and speculation has risen the price of these boards as well (if you manage to find one).

It is quite interesting why when there are shortages of H81 Pro BTC motherboards AsRock still hasn’t found a solution such as releasing a version of their mining motherboard with more up to date Intel chipset such as B150 or B250 for example. It seems that the competition is also trying to take advantage of the situation and grab some of the market that was up until recently dominated by AsRock. Such an example is the recent release of the Biostar TB250-BTC motherboard. The problem with Biostar however is that the brand has a much limited distribution when compared to AsRock and thus is harder to find, not to mention impossible for many markets around the world, so this is actually not a solution to the problem.

AMD’s new Ryzen motherboards are showing some potential for possible use for GPU mining rigs, however there is one serious issues with that platform using the new AM4 CPU socket and that is the lack of cheap low-end processors. That is precisely why Intel is the preferred platform for GPU mining – cheap Celeron processors that do the job well and not so expensive motherboards, though with the lack of AsRock H81 Pro BTC boards the expenses for a motherboard have risen as well. Maybe when AMD introduces lower-end Ryzen APUs things might get more interesting for the miners as well, especially if things with the availability of cheaper Intel motherboards that work for six video cards do not improve meanwhile. Even the cheapest AMD Ryzen 5 CPU at the moment, namely the 4-core/8-threads AMD Ryzen 5 1400 is too expensive for miners when compared with Intel Celeron G1820/G1840 for Socket 1150 or Intel Celeron G3920 for 1151 for example.

With the switch from Radeon RX 400 series of GPUs to the new (rebranded) RX 500 series AMD has also gotten into a bit of trouble with the increased demand from miners. The older RX 400 series of video cards are quickly disappearing and there may not be enough RX 500 series on some markets to cover the demand until the company manages to deliver steady supply everywhere. As a result we have seen some markets that end up with higher priced RX 500 series of GPUs when compared to their RX 400 counterparts when there is actually not much of a difference. Smaller markets are also experiencing serious shortage of video cards due to the increase in demand. Nvidia on the other hand has plenty of GPUs available, however miners are not that much into mining with Nvidia-based video cards due to the higher price, even though they generally are more powerful and use less power in most algorithms. The higher price of Nvidia GPUs combined with the not so great Ethereum (Ethash) mining performance however is driving the demand for AMD GPUs and the recent spike in ETH price has made things even worse in terms of Radeon GPUs availability. Guess we’ll have to wait and see how things will go, but if the price of crypto currencies continues to rise like it has been recently things may get even worse.

MSI Z170A Gaming Pro Carbon Motherboard for 7x GPUs

22, Mar 2017

We got a tip about a motherboard that should be capable of driving seven video cards for mining, namely the MSI Z170A Gaming Pro Carbon, so we got one to give it a try. It is a Z170A Intel chipset motherboard for Socket 1151 processors (there are cheap Celerons available for it) and it uses the newer DDR4 memory. The motherboard is even packed with some fancy extras that are of no use for the purpose of mining, but they do increase the price of the product. Also do note that even if a motherboard has 7x PCI-E slots that does not mean that it will be able to work with 7 video cards connected with x1 to x16 PCI-E risers, it only means that there is a chance that it might work. Unfortunately there are actually not that much such motherboards available and the only few are usually high-end boards with a higher price tag and that is making them not so attractive for miners, especially compared to the use of the popular AsRock H81 Pro BTC motherboard for 6x GPU mining rigs.

The first thing you need to do with this motherboard, prior to attaching any external video card, is to make sure it is running the latest BIOS and if not to update it to version 1.7. This motherboard BIOS is just a few months old and is apparently what allows the particular motherboard to be able to run up to 7 video cards, so make sure you have it flashed before continuing.

The next step is to set some things in the motherboard BIOS. You need to go to the Settings \ Advanced \ PCI Subsystem Settings and switch the PEG0 and PEG1 Max Link Speed to Gen1 as well as set the Above 4G Decoding option to Enabled. These are pretty much the only settings you need to set in order to be able to run 7x GPUs, just make sure you set them in the BIOS before you start connecting the video cards otherwise you may experience instability of the system or it even not properly booting and allowing you to enter the BIOS. So set them first and then everything should be working fine, or almost.

You can see that Windows 10 properly sees 6x R9 390 video cards and a single RX 480 GPU connected in the device manager with the video driver installed and working properly. We actually have a weird issue with this motherboard as after setting up what is needed for it to work with 7x GPUs we are not able to properly get inside the BIOS of the motherboard. If at boot we press F9 to enter the BIOS the system just freezes and needs a restart, if we don’t press the F9 BIOS key it boost into the operating system and works just fine with seven video cards mining or whatever. In order to get inside the BIOS of the motherboard however we’ve had to clear the CMOS memory and redo the settings each time. We thought that it might be a KVM issue, but even with direct PS2 and USB keyboard connection we had the strange F9 freezing issue most of the time, even though a few times it worked just fine actually loading the BIOS and not freezing the system.

Anyway, while we are not entirely sure what is causing the BIOS freezing issue when you try to get inside with F9 after you set the required options to make the motherboard work with 7x GPUs everything else seems to work just fine. The system boots and sees all 7 video cards, even if they are different ones like in out 6+1 configuration, and you can run a miner that will see and start using all 7 video cards. So the MSI Z170A Gaming Pro Carbon motherboard apparently works, though there are still some glitches that may need fixing. The only issue with this motherboard is the higher price and that may be enough of a reason to make you stick with the more affordable and problem free use of AsRock H81 Pro BTC for 6x GPUs instead. Still if you already have a 6x or even less GPUs on some mining rigs and you have a suitable power supply an upgrade to a 7x GPU motherboard might be an interesting choice. Then again you would need to replace not only the motherboard, but also the CPU and the RAM as well, because of the newer chipset used by the MSI motherboard.
