Performance difference between various FSB:RAM ratio? Tags: Memory Performance RAM Computer Last response: August 17, 2008 1:52 PM in Memory Share hohyss August 17, 2008 12:45:01 AM So computer runs at optimal speed when the FSB : RAM ratio is set to 1:1. But what about other ratio such as Example, 5:4 3:4 5:6 1:2 ( ratio when its not 1:1 ) What will be the difference if the ratio is higher or lower? More about : performance difference fsb ram ratio auscanzukus August 17, 2008 1:52:26 PM The ram speed will vary depending on the cpu/ram ratio: i.e. 5:4 = 1.25. FSB 400 * 1.25 = 500 * 2 = 1000Mhz DDR2 Can't find your answer ? Ask ! Publish Related resources Is 1:1 the best ratio between FSB and RAM?
