From 8cab72e1d857d430b5c9c4b748f4b46a84374168 Mon Sep 17 00:00:00 2001 From: Fabian Kunkel Date: Tue, 26 Jul 2016 22:46:23 +0200 Subject: mainboard/bap/ode_e20XX: Add different DDR3 clk settings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds two SPD files with different DDR3 clk settings. The user can choose which setting to use. Lower clk settings saves power under load. SoC Model GX-411GA supports only up to DDR3-1066 clk mode. Both SPD settings were tested with memtest for several hours. Power saving is around half a watt under heavy memory load.
