If it's a real 8x8 and no 16x16 why they insert this extra lanes and show a wrong 16x16 at windows? The consumer will always be wrong about the real thing he bought frown.gif

I thought I had a 16x16 real

That's wrong.

Full 16x bandwidth at the cost of additional latency. It's a switch that routes packets through a buffer.

I found this, don't say much but....

The main difference is that the Z87X-OC Force is equipped with a PLX PEX8747 chip that can double the 16 PCI-Express 3.0 lanes from the CPU. Because of that, the four orange PCI-Express slots can be configured 16/0/16/0, 16/0/8/8 and 8/8/8/8 which supports 4-way SLI and 4-way Crossfire. The black PCI-Express x16 slot is directly connected to the CPU, so if you have one video card you want to overclock you have 0 extra latency. It's a clever solution we've seen before with MSI and ASRock.

Implementation of a PLX chip on your motherboard seems more like a tweak from the manufacturers
to enable 4 Way SLI support on chipsets which cannot normally support it than anything else.

I'll never have 4way sli 😂

I just want that the SLI works at 16x16, don't know much about this plex chips

Only extreme cpus can generate more than 16 pci lanes. Plx chips just help with management.

they cant give more bandwith than what the cpu is set at im sure


No one would buy a 5820k or 6800k if the x16 was true

Well i googled a bit


The plx chip act as a switch


It allow to go from gpu 1 to 2 and allow them to run at x16 individualy


But both at full speed the pcie will be at x8


So in gaming it wortless.
