My motherboard, Intel G41, uses PC3 8500 DDR3 1066 MHz memory. I have 2 GB installed. Since I'll be getting a newer/better graphics card, I want to increase my memory to at least 4 GB (which is what the graphics card packaging recommends). I've only been able to find DDR3 PC3-10666 Memory that says compatible with 1333 MHz on the box. My question is will this memory work in a PC3 8500 1066MHz slot? I mean it says compatible with 1333 MHz but it doesn't say only works with 1333 MHz. It's a question of semantics I guess. Staples was selling this 2 GB DDR3 memory for $4.95 each, so I bought two. I'm affraid to put it in fearing I might damage the motherboard if it's not compatible.
