[SOLVED] RX 570 PCIe x16 vs x4

[NateBeast]

So I have the 970M Pro3 motherboard from ASRock. Per the manual, there are 2 PCIe slots for GPUs.
https://download.asrock.com/Manual/970M Pro3.pdf (pg16)

PCIE2 (PCIe 2.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE3 (PCIe 2.0 x16 slot) is used for PCI Express x4 lane width cards.

However, as you can see on page 6, the SB Chipset blocks the GPU from going into the PCIE2 slot. So I had to put it into the PCIE3 slot. Will there be any noticable performance decrease, especially considering since it's PCIe 2.0 and not 3.0? Thanks so much

Or is there any possible way I can get it into the top slot? Maybe PCIE riser cable?

The chipset wont block anything the card will be above it. use the GPU card in Slot2

I have the card in the lower slot right now but you can see how if I put it into the top slot, it would be blocked slightly by the chipset.

well if you tried it and it did not fit , then your better option is to change the chipset cooler with a little lower one .. much cheaper than using riser cables ...

Edit : you can get copper low profile cooler and change it.

this is an example (I did not check if it fits yet or the TDP )

Thx I'll take a look

I'd also like to know from anybody how big of a difference in performance there will be from 2.0 x4 to x16

Tons of difference , The card is designed to work with 16 lanes PCIe Gen3 , and Gen 3 is double the bandwidth of Gen 2 ...

so you are like using it with 2 lanes only Gen 3 , down from 16 to 2 .

Move it to the top slot. Their no need to change the heat sink.

LOL exact motherboard in the build I listed. Nothing I said or listed was wrong!
Look at the 2nd link of the parts used above!
