I am building a couple semi upgradeable computers for my kids to replace their aging and outdated PIII 550 systems. I am looking at Asus A7N8X boards, because they support 8x AGP, up to 400FSB, 3000+ AMD CPU, and have onboard LAN for easy home networking usage. I have 750 Duran processors, heatsinks and fans from some computers I upgraded for someone else that I would like to use until I can afford to buy larger processors for them. My question is, what ram can I use with this processor on this board? Will the processors work with any of the PC3200/PC2700/PC2100/PC1600 ram the board supports? (I have to buy the ram, and would prefer to go ahead and buy the speed I'll need with the bigger processors.) Please help!
