Both boards use the i840 chipset which is natively designed to support RDRAM but will use SDRAM (from what I understand) with a "Memory Repeater Hub" -- with a performance loss of about 10%. The i820 chipset has already been crushed by "Memory Repeater Hub" problems -- so I was really very worried about using SDRAM with any i840 chipset board... I appreciate all your guys input.
