From b474afdd2118baa6e132f8c756d74cb3be6df071 Mon Sep 17 00:00:00 2001 From: Timothy Pearson Date: Thu, 21 Apr 2016 01:08:01 -0500 Subject: nb/amd/mct_ddr3: Run fence training on each node after memory clock change The BKDG requires phy fences to be re-trained after a memory clock change. Memory training on the ASUS KGPE-D16 and KCMA-D8 somehow "mostly" worked -- without actually following this requirement -- ! Fix the single typo that caused several weeks of delay in putting servers with Kingston RAM (and others) into production...
