PCIe running at x?

[Arwanell]

what is this?

it says PCIexpress x16 slot  running at x16

or running at x4

Are you looking at motherboards or software?

On motherboards it means it's an x4 slot, but they stuck an x16-size socket onto it to make it look like an x16 slot.

In software readings it means the PCIe slot is operating at a lower mode to save power when the full bandwidth isn't required.

oops.

PCIe sockets

yes, mobo's

so, is that bad for performance? I'm going to crossfire, that's why I'm asking

[samcool55]

No, doesn't matter. crossfire is happy with that.

especially with new gpu's and motherboard that both support PCI-E 3.0. Won't have any impact at all.

 

It means the bandwidth that's available.

[Glenwing]

yes, mobo's

If it's PCI Express 3.0, no it shouldn't be a problem.

I know you're talking about MOBO' s, but where does it say that?

so, if it's 2.0 it has impact, but on 3.0 not?

at "slots"

[samcool55]

2.0 4X, yes it will have an impact, like 10%... Not much and not enough to worry.

 

No reason to be scared, just go 4 it and you will be fine!

I had a 2nd gpu running at 4x with pci-e 2.0 and never saw issues related to it having only 4x.

In your MOBO's manual? Or what?

[Arwanell]

okay, that's nice to hear

thanks

[Glenwing]

so, if it's 2.0 it has impact, but on 3.0 not?

Yes on 2.0 it's about a 10% performance loss on average, depending on the game being run.

okay, thanks

the first one that actually had 2x 3.0 slots was double the price of the one I'm looking at  :wacko:
