Do i have enough Lanes for M.2 ?

[MAROON5]

do i have enough lanes to put an m.2 on my pc, i have 2x R9 290x lightning crossfire & i5 4690k

i'm considering "Samsung 950 PRO".

Yes because AMD cards can run a 4x so one will be at 8x one will be at 4x and rest can be for storage.

Unless you're going 4-way crossfire with that 290X, then you're completely fine.

 

People lately have been worrying about pcie lanes. Honestly, it doesn't effect that much. Either way, there will be a connection to the system, whether its through a direct pcie interface to the cpu, or one of the ones handled by the north bridge.

To give you an idea of what kind of bandwidth a modern pcie 3.0 has, you can put a 290X on a pcie 3.0 x4 slot, and not have its performance degraded in any meaningful way in real-world scenarios. That being said, a simple ssd can run on pcie 3.0 x4 without any issue what-so-ever.

You have enough. Your chipset should provide the 2x or 4x connection that your PCI-E m.2 SSD will need. Before you buy, make sure your motherboard has the proper PCI-E m.2 connection. 

 

Your 290x's should both run at a 8x connection speed, since your chipset will handle the SSD.

RTM (read teh manual)

 

it'll tell how if the m.2 is running off of the chipset or the pcie lanes of cpu, most likely the chipset for most boards, but chipset m.2 are slower than pcie ones

 

if you want wicked fast storage, intel 750 series pcie ssd are the fastest of the fastest

your CPU has 16 lanes, motherboard chipset has 4

you can run both your GPUs at x8 and SSD at x4

even if you add more stuff in the future your GPUs can run at x4 x4 without a significant performance decrease

if my gpus are running at x8,x4 i will get the same FPS if they are running at x8,x8 ?

does my mother board has extra 4 lanes ?! that means i have 20  lanes, is that true?

i would go for intel 750 but my huge gpus are covering all the pci slots  beside the m.2 looks so cool

Yes, it honestly wont make a bit of difference.

most do

some have a lot more than 4

usually says in your motherboard manual
