Ok, so ddr2 is not compatible with ddr... Tags: Memory DDR2 DDR Last response: January 15, 2009 7:17 AM in Memory Share shawnsheeps January 15, 2009 3:36:18 AM But this link off HPs website http://www.shopping.hp.com/can/computer/categories/memo... is suggesting ddr2 memory for my labtop. (The memory finder, and then pavilion dv1000...) What really happens if you put ddr2 memory in a ddr slot? They're both 200 pin, you can match up voltage and latency, etc. I know everyone says it doesn't work. I was just wondering... When I open my labtop, it has ddr pc2700 memory in there now...
