Z270i Strix M.2 Question

Morning all!

So I'm in the process of Specc'in up a new rig, and with the deals Asus have on Intel Mobo/cpu combos, its looking to be a damn good deal.

I was looking at the Z270i Strix and noticed it has 2 M.2 slots.

If i slotted 2 Samsung 960 evo's in the board, will they operate at or close to their rated speeds?

Thanks much!

I have far too little knowledge of PCI lanes etc to answer this, since I assume they take up those PCI lanes, hence why people take CPUs which has many "lanes"?... To be honest, I have never really understood it all. But IF I'm on the right track, then I assume it depends on your CPU a bit and the number of PCI lanes it supports.

Short answer = It shouldn't be a problem.

Long answer i cannot be 100% sure, but. PCIe 3.0 = 1GB/s pr. lane
The 6600k, 7600k, 6700k and 7700k all have 16 lanes. = 16GB/s

According to techpowerup there is no differance for a 1080 in x8 vs x16 = it uses under 8GB/s

And the 960 if 1TB version is 3200Mbps = 3,125 GB/s x2 = 6 GB/s + 8GB/s from the GFX
Thats under the 16GB/s available. (If my quick and dirty calculations are right )

Not right on this one as the M.2 PCIe lanes are separated from the GPU's PCIe lanes with Z170 and Z270.

With Skylake there are 4x PCIe 3.0 lanes for storage while Kaby'Lake has 8 lanes for PCIe.

If you use Kaby Lake with a Z270 series board you will have 8 PCIe lanes that are exclusively for M.2/U.2/PCIe storage.

This means that you can use two M.2 devices with no real issues and without interfering with your GPU's PCIe lanes.

Arr sorry for the misinformation.

Intel lists Up to 1x16, 2x8, 1x8+2x4 as possible PCIe options.
Thought that was in all.

You should be able to use two m.2. drives at full speed without any issues. If you were using AM4 instead, this isn't likely to be the case.

Kind Regards
