I have an original 845 motherboard, asus p4b. (Running sdram) Currently I have a 1.6 piv with the 256 cache. Does anyone know if the new piv will run in this motherboard. I know it supports the northwood core and it would seem I could just run the board at 133. I have pc133 memory so I could set the memory adjustment at 1:1. At 133 the agp is at 66 and pci is at 33. The board and processor were given to me last month, when prices drop a little I would like to be able to throw in the new processor. I do a small amount of gaming but not much and do not want to buy a new board and memory.
