No, check our review of the Skylake CPUs. We covered the Z170 chipset in this review too.The Z170 chipset gives you 26 PCI-e lanes, the CPU another 16, total of 42 lanes.
6 are reserved for USB3
2 are capable of handling 2 gigabit ports
M2x4 x 2 is another 8 lanes, IF they're both in use simultaneously
Worst case then is 26 lanes remaining. That leaves enough with some simple switches to handle a full x8/x8/x8 tri-GPU setup. YES, it does mean whomever is putting it together will actually have to plan out the build appropriately, but why would they not give the people the option? Doing it this way makes it impossible to utilize the flexibility that the new Skylake setup allows.
Have you heard of PLX chips? Those hardware PCI-E controllers that essentially gave you more PCI-E lanes? Those chips have been used on several motherboards over the years. They didn't increase the actual bandwidth coming from the CPU, but through hardware manipulated the available bandwidth and the additional connections to provide increased performance.This article is what's flawed, not Biostar's design.
Yes, on paper the Z170 chipset offers 20 PCIe 3.0 lanes. But it's idiotic to suggest using them for Crossfire (let alone SLI). Because between the CPU and the chipset is only a DMI 3.0 connection, and its bandwidth is equivalent to PCIe 3.0 x4. And that has to serve EVERYTHING connected to the chipset. Hooking a GPU up to the chipset PCIe lanes is inferior to giving it a dedicated PCIe 3.0 x4 connection straight from the CPU. So the x8/x4/x4 design Biostar picked on its Z170X board is superior to what the author is suggesting here.
Several in fact!So....what, exactly, is the point of having multiple NICs? Even if you had dual connections through your router, that would only help your LAN file transfer speeds (which are already able to reach Gigabit speeds on standard routers), & won't affect your Internet speed (all Internet is limited by whatever broadband connection you have to your house, most of which are not only nowhere near Gigabit speeds, but also ends up just splitting the connection between both NICs, so you don't get any increased speed anyway).
But sadly Intel gave up their motherboard division a while back. They were not the prettiest of boards... but they were rock stable and would run for years. The school I am working at is just now starting to have mobo issues with their intel motherboard Pentium D systems which have been running non-stop for the last 10 years in all manner of heat and humidity during the summer and bitter cold in the winter. Maybe now that a few are dying off I can convince them to upgrade to i3 and i5 systems.Avus is right. Biostar is so so close to the bottom of my motherboard choices for the systems I build, that whatever the color scheme, the format or the product they have, it's not gonna be a concern, unless ASUS, Gigabyte, MSI, EVGA, ASRock (in that specific order - I rarely see myself going past the second option) can't get a specific thing right - chances are very low for that to happen across all manufacturers mentioned, BUT...if it happens, I might turn to...that's right....INTEL and only after that to Biostar.
So Rookie MIB was right: Z170 technically does have 26x PCIe, but USB 3.0 automatically chews up 6 of 'em.Six of 26 are used up by USB 3.0 (which is where "up to 20 PCIe lanes" comes from)
