Recently decided to upgrade the RAM on my old Samsung R530 laptop. It had previously had 1x1GB and 1x2GB installed. A few months ago I replaced the 2GB with a 1GB.
Anyway. Bought a new 4GB Kingston stick, DDR3 PC3-12800. The two sticks that are already in are both 1GB DDR3 PC3-10600. Popped the new stick in, powered it up, and was presented with a black screen. The only status light is the power indicator. Nothing else. So I pulled the 4GB out, stuck the old one back in, and it booted fine.
I checked with Samsung to confirm the max memory, and it's 8GB, so this shouldn't be an issue? The only thing that concerns me is that the new ram is 12800, and the old one is 10600, but as far as I'm aware, the two are inter-compatible, it'll just scale itself back.
Does anyone have any ideas as to what the issue could be? The new RAM is used, but I bought it from a store that claims to test their products before selling them. Could it be they're somehow compatible with whatever they tested it on and not with my laptop?
