Were you able to make the system stable with CMK256GX4M8A2400C16 kit? I am having BSODs from time to time. Did you adjust any BIOS settings? ]]> Thu, 14 May 2020 10:10:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=75455&title=256gb-ram-on-x399-professional-gaming-motherboard#75455 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=74563&title=256gb-ram-on-x399-professional-gaming-motherboard#74563 Author: Knasterhuis

Just wondering whether you got it working with 256 GB ram. Which processor are you using?

may be also tell their staff/HQ to update their memory QVL, https://www.asrock.com/mb/AMD/Fatal1ty%20X399%20Professional%20Gaming/index.asp#Memory

at this time to writing, no 32GB in the list.]]> Fri, 20 Sep 2019 17:31:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=68073&title=256gb-ram-on-x399-professional-gaming-motherboard#68073 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=68015&title=256gb-ram-on-x399-professional-gaming-motherboard#68015 Author: crion

Yes, saw a 3.70 BIOS update for the Fatality X399 about 32GB support.

However the Memory QVL's are pretty empty on 32GB DIMM support. Buy branded good memory for AMD processors, preferably Samsung b-die if they exist in 32GB DIMM size. Atleast they have in 16GB DIMM size.]]> Wed, 18 Sep 2019 20:40:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=68015&title=256gb-ram-on-x399-professional-gaming-motherboard#68015 https://forum.asrock.com/forum_posts.asp?TID=12298&PID=67209&title=256gb-ram-on-x399-professional-gaming-motherboard#67209 Author: dhtp

Hi,

I am interested in purchasing the x399 professional gaming motherboard:
https://www.asrock.com/mb/AMD/Fatal1ty%20X399%20Professional%20Gaming/index.asp

However, I want to check if it supports 256GB ram kits that utilize 32GB modules:
https://www.corsair.com/us/en/Categories/Products/Memory/vengeance-lpx-black/p/CMK256GX4M8A2400C16

Corsair claims that their modules are supported by the x399 platform, but I am not sure about this particular board. I understand that ASRock lists the RAM limit at 128GB, but that may have been due to the lack of 32GB modules when x399 and the motherboard came out.

Has anyone tried those new kits on this motherboard?

Thanks!
