Ermmmmm...looks like I made a mistake on the motherboard I bought...

[Mr.Meerkat]

So basically I was confronted with 2 options (as they were cheap) when I was buying my motherboard for my upcoming ITX build, an asrock H110m-itx/ac and an asrock H170m-itx/ac and I picked the H110 motherboard as it was $20 cheaper (or 2000 yen to be precise) while the main differences to me between the 2 motherboards is one is H170 while the other one is H110 and the H170 motherboard has 2 gigabit ethernet ports (everything else doesn't bother me...).

 

The H110 only has 6 PCIe lanes where as the H170 has the full 16 PCIe lanes (my bad for not doing the research) so simply, is 6 PCIe 3.0 lanes enough for a nano or a 1060 or a RX480? I've ran a 290X before on a 4X slot with minimal bottlenecking and a 7950 on that h61 motherboard with little bottlenecking so can I expect it to be fine? If not then trip back to Akihabara then...(or sell it back in UK and make a £15 profit then get the H170 motherboard there). Or have I got this wrong and the number of lanes stated on the chipset doesn't mean anything? 

 

TL;DR Is 6 PCIe 3.0 lanes enough for a 1060 or a nano or a RX480 without any bottlenecking?

The H110 has 16 PCIe 3.0 lanes coming from the CPU going to the PCIe 3.0 x16 slot.

Ah, so the number of lanes supported by the chipset doesn't matter then?

Where did you get info that it have only 6 lanes?

That number isn't even possible.

 

It's either 16 or 8 or 4.

I have never saw 6 line PCI-E.

Here you can see that this motherboard have full x16.

In this case, no. You would be able to use the slot at its fullest, and the M.2 slot at the same time.

Supported Processor PCI Express Port Configurations

1x16

 

That's what you need to know.

That PCI lane on motherboard won't go over chipset, but directly to CPU.

So it will work on 16 lanes.

The h110 has 6 pcie lanes from the dmi compared to 8,10,16and 20 on the higherend chipsets. The lanes from the cpu are the same.

Thanks, this is very reassuring (and how I saved $20 with going to the lesser chipset ).
