Thread: Performance by memory increase

I recently upgraded my memory from 1 GB DDR2 667 to 3 GB DDR2 667. I got a warning message that said for max performance there should be identical memory sets in both slots, so my question is whether I wasted money buying 2 GB RAM or will there will be an improvement in performance. My motherboard is an Intel D945GCCR and the processor is an Intel Core 2 Duo 2 GHz E4400. I have two hard drives in my PC, one used for regular use and other for backing up data both are internal disk. The backup disk is used twice in a month so I only disconnect the SATA data cable. After use, the power cable left connected so I learnt that it consumes power when it is idle. Since then, I've been disconnecting the power cable each and every time but it is tricky and dangerous. Can you suggest other means to do the same?

There will definitely be some performance boost with 3 GB of memory. You'll be able to run many larger programs simultaneously. If you use Windows Vista, that requires a minimum of 1 GB. The upcoming Windows 7 will comfortably run on your system with the amount of RAM you have now. Besides, DDR2 memory is at an all-time low, so you haven't really wasted your money.
