From 9f87ad2c2f977670d06d55ce5af45560e3a32677 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20=C5=BBygowski?= Date: Sat, 15 Oct 2022 12:38:35 +0200 Subject: mb/msi/ms7d25: Add support for DDR5 variant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The DDR5 board is almost identical to the DDR4 one. The only major difference is the board's DDR5 memory design. TEST=Boot MSI PRO Z690-A board successfully to Ubuntu 22.04. Memory: Crucial CT8G48C40U5.M4A1 in all 4 slots.
