Nope, it's a HW limitation of this chipset. There are no workarounds. It's not just an ASRock's thing.

Sadly, you'll have to reach deep into your pocket.]]> Tue, 02 Apr 2019 01:36:08 +0000 https://forum.asrock.com/forum_posts.asp?TID=11237&PID=61923&title=b450m-pro4-server-setup-with-ecc-memory#61923 <![CDATA[B450M pro4: server setup with ECC memory : If this question won&#039;t be...]]> https://forum.asrock.com/forum_posts.asp?TID=11237&PID=61922&title=b450m-pro4-server-setup-with-ecc-memory#61922 Author: puchuu

If this question won't be resolved I will buy some asrock x470 solution without this limitation. But it is expensive. ]]> Tue, 02 Apr 2019 00:56:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=11237&PID=61922&title=b450m-pro4-server-setup-with-ecc-memory#61922 <![CDATA[B450M pro4: server setup with ECC memory : Hello.

Hello. I saw on reddit that ASRock B450 pro4 supports ECC memory for ryzen. I want to build a small server with 12 HDD and 1 m.2 nvme SSD with ryzen 2600/2600e.

I want to install:

  1. m.2 nvme SSD into first x4 slot

  2. LSI 9260-8i into first x16 slot (running in x8 mode)

  3. any low power video card into second x16 slot (running in x4 mode)

  4. additional ethernet adapter in any x1 slot



The problem is that ASRock B450 pro4 (atx version) has a text in specification:

If M2_1 is occupied, PCIE4 will be disabled.

I don't want to disable PCIe x4, there will be a video card inside it. I don't want to install nvme SSD into second x2 slot. I don't want to drill a hole in x1 slot.

Is it possible to disable other PCIe lines instead of x4 slot?

Than I opened specification for B450M pro4 and I can't see text about M2_1 and PCIe x4. So I should buy micro ATX version instead of ATX?

Thank you.]]> Tue, 02 Apr 2019 00:26:31 +0000 https://forum.asrock.com/forum_posts.asp?TID=11237&PID=61920&title=b450m-pro4-server-setup-with-ecc-memory#61920
