Systems shipped with 533MHz FSB processors require DDR333 (KTD4550/xxx) parts. MODULES MUST BE ORDERED AND INSTALLED IN PAIRS for Dual Channel mode. This system is configurable and may ship with a different amount of standard memory. ======================================================== So you may have the wrong speed ram causing the errors in dual-channel mode, or you may just have a bad module. I don't know any ram that is NOT guaranteed for life, so if you have a bad module contact the manufacturer and get it replaced. -Derek At 12:16 PM 1/27/2006, Philip Juels wrote: >I switched the DIMMs from dual-channel to single-channel and so far (up to >test 4) I get no errors.
