Looking for the motherboard with the MOST PCI-E lanes possible!

[LtRoyalShrimp]

Hi guys,

 

For reasons, i'm looking for the motherboard that has the most PCI-E lanes. Does not matter size or speed, simply that it has the most physical PCI-E slots. 

 

Socket number(1150, 1151, etc) also does not matter.

This is limited by the CPU, not motherboard. I take it you mean PCI-E slots and not lanes?

Do you mind 2011-3?

Look at Asus/MSI high end X99 boards and use the comapre feature if you mean Pcie slots.

[Sam Z Man]

That's controlled by the CPU and chipset, I doubt you would need more then the Z170 chipset offers though.

Slots. Not lanes.

 

The number of PCI-E lanes you have all depends on your processor.

 

And the most PCI-E slots or lanes you will find will be on X99 hardware.

 

Also, @LtRoyalShrimp don't forget to follow your topics

X99-WS with a 5960X

[shypin]

ASUS X99-WS supports x16 on all lanes in a quad SLI

use a 5930k / 5960x with it

what are you talking about? I assume you mean slots?

[NumLock21]

Most number of PCIe lanes will be a Haswell-E cpu like the 5930K or 5960X and Haswell-EP, that's Xeon E5 xxxx v3, all of them have a total of 40 PCIe lanes. The Asus X99-E WS has a PLX chip, where it will provide additional lanes. Can't remember how many in total, I think the PLX has 48 more or the total combined with cpu is just 63. For the number of physical slots, maximum allowed on a motherboard is 7, unless you find some non-standard board that has more than 7 physical slots.

On Skylake it's the same with number of physical slots, but for PCIe lanes, the cpu has a total of 16, chipset itself has 20, that gives you 36 lanes. Dual gpus uses 16 lanes, and the rest, goes to other parts like M.2 or PCIe SSDs.

Chipset sits on mobo, chipset holds A LOT of PCIe lanes. This is true for like, every mobo and every CPU both AMD and Intel.

It's limited by the CPU... 5820K has 28 lanes, 5930K and 5960X have 40 lanes on the same boards. 

Maybe with some PLX chips you can do some magic, but that doesn't change the fact.
