CPU with m.2 nvme

Recommended Posts

Posted · Original PosterOP

Hello I have a quick question because I am new to pc and was just curious if this works.

 

my question is does an i5 9600k cpu have a limitation to how many m.2 it has like say in the far future I want more m.2’s and I get asus hyper m.2 x16 card.
Will my cpu have any issues with more than 2 m.2’s?

 

im not even sure if it even has anything to do with the cpu or not but that’s my question thanks.

If you add too many m.2 drives your pc can run out of PCIe lanes

your CPU has 16

That depends on motherboard model as you need PCIe bifurcation for this.

 

Note that you do have a max speed limit for all M.2 and SATA storage combined if you use a graphics card unless the board supports SLI, which realistically is somewhere between 3500MB/s to 3800MB/s. That's because all these storage is connected to the chipset in this case, which only connects to CPU with PCie 3.0 x4 equivalent of bandwidth

All depends on motherboard and available slots.

Take in consideration that M.2 can also be connected via chipset (at least that's the case with AMD, but I guess with Intel too). Although the bandwith may not be as high as a directr connect to CPU, in most cases you will "feel" the difference only with VERY intensive storage utilitzation. You should study the Motherboards manual carefully. It will tell you in which combination you can use M.2 and PCIe slots. Because sometimes they share bandwith and it's not optimal to use all connections available, in some cases even with SATA or USB ports.

On Intel mainstream platforms the m.2s are always connected to the chipset, can't have them on the CPU without losing the x16 port / downgrading it to x8 on a mobo that supports bifurcation.
