I have always been an intel slot 1 guy....however I have now taken the plunge and built (2) AMD systems, one power and one budget. The power system is great! My question is, on the budget system, I used a AMD athlon 1700+ XP chip with a ECS K7S5A mobo and 512mb of PC100 ram (just cause I had it laying around). When I first booted up the system it only saw the processor as a AMD 1152 or something like that, no problem, went into the bois and changed the mhz to 133 and viola a AMD1700 BUT it also took the ram up to 133. The system has been running for a few days now and seems to be ok, but if the ram is in fact pc100 and the bus speed is set to 133 will I have problems? In the bios you could set many different bus speed combinations but 133mhz processor and 100mhz ram was not one of them? Any feedback? Thanks.
