Over the weekend my dad's computer took a dive when his hard drive crashed. He has an older Compaq AMD SR1417CL model-Sempron processor and a single 512MB PC3200 on the board. I'm buying him a new hard drive however I'd like to upgrade his ram. I have a pair of 512MB PC3700 466MHz DIMM's from an older PC I've junked. Is it possible to swap those in place of the 512MB chip he has there already? It just saves us $40.
