With the recent spike of interest in GPU mining thanks mostly to Ether a lot of people are getting back to building GPU mining rigs using more up-to date hardware much like back in the days of the Litecoin and prior to that of the Bitcoin mining boom. Nowadays it is much easier and you have way more options for different motherboards that have the option to work with 4, 5 or even 6 video cards by utilizing not only full width x16 PCI-E slots, but also the multiple available PCI-Express x1 sots with the help of extenders. We have prepared a list of all possible candidates for use as motherboards for multi-GPU mining rigs 4-6 GPU mining from ASRock, the company that has made its name among miners thanks to their dedicated BTC-branded motherboards made especially for GPU mining rigs. Other motherboard manufacturers such as Asus, Gigabyte, MSI and others also have products that might do for a multi-GPU mining rigs, but these are not dedicated for such use and this may cause some problems. Nowadays ASRock has a lot of BTC-branded motherboards that are designed for use as multi-GPU mining rigs for different processor platforms from both AMD and Intel. There are also quite a few more non-BTC named motherboards that could do the job perfectly and some that might also work fine, but some of the PCI-E slots might not be available for GPU use under specific conditions, so you need to be careful. What is important for a motherboard that will be used with multiple GPUs for mining is for the motherboard to have enough PCI-E slots, to be affordable in terms of price as you don’t need extras targeted at gamers or enthusiasts and to be able to be used with cheap dual-core CPUs. The Genesis Ethereum Mining contract is the latest offering from the reputable provider of outsourced crypto mining contracts. The contracts have a lifetime of two year and the Company guarantees 100% uptime by substituting their own equipment. There are no extra fees to pay on top of the original price. Oct 23, 2013 - “This also means that the manufacturing cost of scrypt ASICs will be significantly more expensive than that of SHA-256 ASICs.” Nevertheless, some companies. He was mining SHA-256 and scrypt-based coins with a 20-GPU setup, but it was costing him £600 per month, he said. “What's important is the. ASRock’s BTC-branded motherboards do come with some extra features that may help by minimizing possible issues such as the fact that they have been designed to provide extra power to GPUs and have dedicated connectors for additional power from the PSU. They do not share PCI-E lanes with external hardware such as network controllers, audio cards, storage controllers or USB controllers that may cause problems if you want to use all of the available PCI-Express lanes for video cards and so on. These motherboards are offering just basic features, but ensure stable and problem free operation even under not so good conditions that often are available with GPU mining rigs that generate a lot of heat an may not be optimally cooled. The list below covers all possibly suitable ASRock motherboards for 4-6 GPU mining rigs, you should choose to go for the models that do have the BTC in their model nae as they will most likely be the best choice. The next are Anniversary and Pro series and then the others if you have no other choice, but with such a big list you should have a lot of options. Unfortunately the only 6 GPU capable motherboards are for Intel socket 1155 and 1150 CPUs, still no affordable options for the latest Intel 1151 platforms or AMD FM2 sockets. Sure the company has some high-end enthusiast level products that can do 6 GPUs, but these are pointless for use as multi-GPU mining rigs as they will add to much to the price of the setup and you will be better off spending the extra cash for more video cards or more powerful models. After all you need to find the right balance that includes cheap motherboard, cheap processor and powerful GPUs along with some PCI-E extenders (powered preferably) with being the best choice if available.

Here is something interesting that is not originally intended to be used as a GPU mining rig, but for a powerful compute oriented machine – an 8x GPU AsRock Rack Barebone populated with eight Nvidia GeForce GTX TITAN X video cards and two 14-core Intel Xeon processors. These powerful rackmount systems are designed for use with Nvidia Tesla cards for high-performance CUDA applications, but you can put in GeForce cards as well such as the TITAN X and have them all running at PCI-E 3.0 x16 speeds (no SLI support is available). So we took one of these interesting systems and ran a quick test with the latest ccMiner to see what kind of performance we are going to get for crypto currency mining. It was out of curiosity as the system is not intended to be used for GPU mining – the whole things is just way too expensive to probably ever see ROI let alone make some profit from mining. Interestingly enough the 8x GPU configuration requires the use of Windows Server or compatible Linux distribution, with Windows 7 or 8.x we were having trouble making all 8 GPUs work properly (Error code 43 on the 8th card). Apparently there is a solution to make all 8 cards work fine under these consumer versions of Windows as well, all you need to do is some and you should be fine. As you can see from the screenshot the system runs fine with a total hashrate of about 190 MHS mining Quark (98 MHS total on X11 and 25MHS total on Lyra2RE) on all eight GeForce GTX TITAN X GPUs. This means that a single TITAN X card gets you about 24 MHS for mining Quark-based crypto currencies and ll of the cards manage to provide optimum performance. Notice that the fans are turned all the way to 100% for best performance, because otherwise the cards are easily hitting the thermal limit with their fans running on auto at about 50-60% and as a result they throttle down and you loose performance with the GPU frequency dropping down to 1000 MHz. Again this is not a system designed for crypto currency mining, but for compute applications, we were just curious how well it will perform for crypto mining and it does a great job with some tweaking. Of course since the whole thing is designed to be in a server room the noise level is not relevant, though it is quite high as expected thanks to the 8 GPU fans and the other 8 chassis cooling fans that are 24W each when running at maximum RPM. Maybe if GPU mining picks up to a large scale level like it is happening with Bitcoin mining and is profitable enough we might be able to see solutions like these used, but for now these are limited to businesses using them for high-performance CUDA applications. Think along the lines of 3D design, visual effects rendering, medical imaging, energy exploration or scientific simulations etc. Copyright ©2014-2018 - - All About BTC, LTC, ETH mining as well as other alternative crypto currencies.
