Problem is partially solved. Lowering to PCI-e Gen2 worked.]]> Sat, 23 Jan 2021 14:14:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83345&title=b550-pro4-support#83345 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83336&title=b550-pro4-support#83336 Author: Talisman_Chick

Oh, no.
First PCI-e x16 slot is connected to CPU PCI-e Gen4 line.
Second PCI-e phisically x16 slot has only x4 Gen3 line from B550 chipset.

If you reverse motherboard, you can see it.]]> Sat, 23 Jan 2021 00:16:21 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83335&title=b550-pro4-support#83335 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83332&title=b550-pro4-support#83332 Author: muziqaz

If you put your card into pcie slot number 3 on your motherboard, it should in theory work at either x16 or x8 at least.
PCIe slot 3 works at x4 speeds only when PCIe slot 1 has GPU as well working at full x16 speed.
Doesn't hurt to try to see if card works in that slot ;)

If all else fails, last reset would be to reset the BIOS and then add the card to primary slot.
Also, do you have other display port or HDMI cable to try out. I know I'm grasping for straws here, but you never know ;)]]> Fri, 22 Jan 2021 23:47:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83332&title=b550-pro4-support#83332 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83331&title=b550-pro4-support#83331 Author: Talisman_Chick

No, you will not feel any speed difference on your 5700xt even on pcie3 x8 speed ;)
I have my Radeon 7, which is faster than 5700xt in pcie3 x8 slot, and 5700xt itself is in secondary pci-e slot, and have no issues with performance :)]]> Fri, 22 Jan 2021 23:17:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83329&title=b550-pro4-support#83329 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83328&title=b550-pro4-support#83328 Author: Talisman_Chick

Card works in any PCIe gen slots. It does not need to be Gen4 :)]]> Fri, 22 Jan 2021 21:29:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83325&title=b550-pro4-support#83325 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83324&title=b550-pro4-support#83324 Author: Talisman_Chick

First, drop memory speed to minimum default, then try. If not, try different PCi-e slot, if not, try different display port slot on card, or HDMI]]> Fri, 22 Jan 2021 20:01:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=17686&PID=83320&title=b550-pro4-support#83320
