MSI Releases Special E7A71IMS.120 Motherboard BIOSes for Mining
MSI has released BIOSes for multiple motherboards that help cryptocurrency miners to use, say four to six graphics cards on their motherboard. Much like graphics cards, affordable and capable motherboards are now also in high-demand and running out of stock.
It is relatively harder to acquire the economic mining motherboard due to the fact that Intel slowly discontinued the H81 and B85 chipset, and this caused the shortage of mining motherboards in the market.
Users found a new way out along with the release of the 100-series chipset, yet many of them found that when they attached 6 AMD graphics cards on the 100-series motherboard, even though the board successfully recognized 6 graphics cards, there were always exclamation marks on 3 or 4 graphics cards within device manager in the OS. And, of course, the cards with exclamation marks would not function properly during mining. MSI consistently heard such inquiries from customers.
Hence, MSI does a series of tests for its products and picked a couple motherboards including Z170-A PRO, Z170A SLI PLUS, Z170 KRAIT GAMING, Z170A KRAIT GAMING, Z170A KRAIT GAMING 3X, Z270-A PRO, H270-A PROwhich fit the purpose of mining. There are few things that need to be done before mining and it will be explained in the paragraph below using MSI Z270-A PRO as example.
Update BIOS
MSI has patched solutions especially for PCIE device recognition on the boards which are mentioned above. The “above 4G decoding” option is added to BIOS which allows the motherboard to efficiently allocate resources for all 6 graphics cards.
Download BIOS, E7A71IMS.120 which supports bitcoin/ethereum mining -> Copy it to the root folder of USB pen drive -> Connect USB pen drive to motherboard USB port -> Start the system and enter BIOS -> Choose M-Flash -> Select Yes to continue BIOS flash.

System will reboot and enter M-Flash user interface. Please find the USB pen drive on the left panel, select the USB pen drive and the BIOS file will show up on the right panel. Choose E7A71IMS.120 and click yes to start the BIOS flash.
After BIOS flash, boot up the system with CPU integrated graphics without adding any discrete graphics cards. Use Win10 professional 64 bits as your preferred OS and install all the relevant motherboard drivers after the OS installation.
Graphics Card Driver Installation
Under BIOS setup, set Settings\Advanced\Integrated Graphics Configuration\Initiate Graphic Adapter to be IGD.

ASIC resistant algorithms most of the time its done by using a lot of memory and adding memory to an ASIC makes it a lot more expensive to build one. and videocards swim in memory.
so the coins are mostly tailored to fulfill this role like ETC ETH
During the tail of the previous cryptocurrency bubble, I would read that ASIC's were better for this purpose than GPU's. What's changed?

I wonder what effect this has on cheap GPU CF? Maybe hack in 4x ~ 6x cheap ass GPU? ...Like HD 7850.

The effect should be negligible. Most GPGPU tasks don't utilize much bandwidth at all. They also have no need for CF (or SLI). I have a BOINC rig using mixed GPUs (Nvidia and AMD) and it works just fine. But, I don't know if Etherium works best in CF or SLI. I figure it'd be worse, since that would require the GPUs to synchronize their data, which is just wasting time.

Not talking mining, but gaming. Since this should better manage bandwidth.
To OpenCL CF/SLI still presents itself as set of separate devices.
