PCIe Lanes Help!

[Ryan-Simpson]

Hi awesome community

 

This might be a bit of a stupid question and I think I know the answer already, but before I run out and spend my hard earned pennies on some new SSD’s, I want to make sure I’m right.

 

Basically I will be upgrading to 2 new GTX 1080’s SLI, and I am currently using an Intel 4790k.

 

My question is this:  If the 4790k has 16x PCIe lanes and the GTX 1080’s require a minimum of 8x each to run, will I need to lose my m.2 950 pro that is currently using 4x PCIe lanes?    

 

Thanks for the help

shitty processor isn't it?

Depends on the motherboard, and whether the M.2 slot uses PCIe lanes from the CPU, or uses the auxiliary lanes provided by the chipset.

16x PCIe lanes seems kinda tight these days what with PCIe storage being so boss and getting so popular now.  Was thinking about moving to x99 but as I am just a gamer I cant justify the cost of a new chip, motherboard and RAM whan i dont do anything that CPU intensive.

if im correct 1 card will run at x8 the other will run at x4 and with you're m.2 that will run at x4

If you're using a x16 that's electrically x4 probs are that's wired to the chipset

EDIT: oh m.2, still the same thing

That uses a PCIe 2.0 ×2 M.2 slot wired through the chipset, so it won't interfere with your CPU/graphics card lanes. You can run ×8/×8 graphics cards and the M.2 SSD at the same time.

The black x16 slot (which is x4) is shared with m.2, so that one is disabled if you've an M.2 drives, for SLI you've to use the red ones, both will work at x8 when 2 GPUs are installed

so will it be OK to just leave the M.2 or will I have to disable it?
