As after installing FS9 I could see some performance problem looming in the future, also I decided to order 500MG (2 x 250 as it is a dual channel 400Mhz DDR) for my PC.If any of you guys have increased the PC memory could you give me a tip or two of what must be done?I believe that I need to increase the cache memory (1.5 times the memory I think). Is there anything else to do? Will the PC realize that there is more memory available now? Or shold something be done in the BIOS (I hope not).Roger

Sorry.I meant Page file, not cache memory.Roger
