From 84e8037a433ff01ae83aa95a68e807e4530da4fb Mon Sep 17 00:00:00 2001 From: Matt Parnell Date: Mon, 11 Sep 2023 23:16:25 -0500 Subject: mb/system76/rpl: Allow 5600 MT/s memory for RPL-HX System76 only sells units with memory speeds up to 5200 MT/s, but the i9-13900HX supports up to 5600 MT/s memory. Tested by running memtest and checking dmidecode reports 5600 MT/s when using 2x16 GB 5600 MT/s Crucial SODIMMs (CT2K16G56C46S5) on addw3, bonw15, serw13.
