Tags: Memory DDR2 Laptops RAM Last response: July 25, 2011 12:36 AM in Memory Share ruibullseye July 24, 2011 8:44:37 PM Hey everyone, i got 1 modules of memory ram, 1x 2gb 667 Mhz ddr2 i've acquire a used laptop who got 1x 2gb 800 Mhz ddr2. and got 2 slots available one being used right now. My question is, is it possible having one slot with 2gb 800Mhz ddr2, and the 2nd slot with 2gb 667 Mhz ddr2 making 4gb ram ddr2 ? The laptop can only have memory ram ddr2 800/667 Mhz to a maximum of 4gb. More about : ram speed slots geofelt a c 97 } Memory a b D Laptop July 24, 2011 9:31:14 PM Try it, it will probably work. But, the ram will operate at the lowest common denominator of speed and latency. By and large, more ram is better than faster ram anyway. Particularly if you are a big multitasker. ruibullseye July 24, 2011 11:08:49 PM bum for more opinions Can't find your answer ? Ask !
