X470 PCI-E 4.0 support

What does Asus mean when they give "limited PCI-E 4.0" support on some of their x470 motherboards. Is it like on some boards or to some extent??????

PCIe 4.0 is x570 only. (AFAIK B550 and A520 will not support PCIe 4.0)

Some boards. Depending on the traces and the quality of the PCB they have been able to transmit PCIe 4 signals to the top x16 slot. However i believe that AMD is removing this as a possibility in one of the next micro coded updates.

It used to have PCIe 4.0 enabled but that has since been disabled. X470 now no longer offers 4.0 compatibility


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

EVGA G3 thread, Seasonic Focus thread, S12II/M12II thread, Userbenchmark (Et al.) is trash explainedˢsͥˡ ͮuͤ ͬˢgͭ ͦᶰoͤ
