hello everyone i have an advent 9117 laptop which has 2 x512mb of pc 3200 running vista premium.here is specs web sitehttp://www.uktsupport.co.uk/advent/laptop/9117.htm Vista uses most of the 1 gb so i need to uprage memory. I wanted to know if i can use faster memory eg 800 mhz and if so will bios detect it and run at that speed or will it harm laptop . will the memory just run at the fastest speed it is capable of running or set at in bios. i know its got to be 200 pin sodimm ddr2 and a max of 2 x 1gb its the speed of the memory which im wondering about . so if anyone can explain about putting faster speed memory in i would be grateful many thanks paul
