I’m looking into a cheap mobo and came across the ECS K7S5A Pro http://www.ecs.com.tw/products/pd_spec.asp?product_id=269 This mobo has 4 DIMM slots, 2 for SDRAM, 2 for DDR SDRAM. I currently have in my older PC SDRAM, but 3 sticks. I was wondering if it was possible to use SDRAM and DDR SDRAM at the same time with this mobo? Personally, I don’t think so. But I’ve only really been reading about this stuff for a week or so. Hehe. Thanks!!
