I've got an old white box with an EliteGroup (ECS) K7S5A (Rev 3.X) motherboard, which has 4 memory banks: 2 for SDR SDRAM modules (168-pin) and 2 for DDR SDRAM modules (184-pin).
It supports non-ECC, unbuffered modules only, up to a total of 1GB. Currently has one 256MB SDRAM PC133 module in it and I want to add a new 512MB module.
The issue is that Crucial's System Scanner recommends me to upgrade through a choice of DDR modules, while Kingston's website states that "This board supports both DDR and SDRAM memory technologies. However, they cannot be mixed at the same time."
So I'm pretty confused! Any advice?
MANY thanks in advance to everyone who can help!
