OK I have a motherboard which supports DDR3 memory. Currently I have 2 * PC3-10666 2GB in it (4GB total). I plan to remove them and replace them with 4 * PC3-12800 2GB (8GB total).
My motherboard supports:
4 x DIMM, Max. 8 GB, DDR3 1600*/1333/800 Non-ECC,Un-buffered Memory
Dual channel memory architecture
Can I safely assume that my new PC3-12800 DIMMs will work with my motherboard (which uses PC3-10666 currently)?
