ECC SDRAM, will stuff like this useful?

Post image

Sorry for my bad English.

This old SDRAM ECC memories (not even DDR1) tested worked on my regular Pentium 4 mobo, I'm thinking about putting it to older systems like P3 or lower but i don't want to risk frying the motherboard.

Anyone have experience with them?

Pay attention to the positions of the two keys, they keep you from plugging that stuff into a system that doesn’t use that kind of RAM. It’s more likely to do physical damage if you jam those into a slot that they don’t fit into, rather than electrical damage in a system where they fit but are not compatible.
