New Mobo, P45 Or X48? in Processors, Motherboards and Memory Posted August 4, 2008 · Report reply looking for a new mobo and will overclock intel e8400, i was thinking about asus rampage, but which chipset is better for overclocking P45 or x48, i have to choose from Asus Rampage, P5Q DELUXE, Gigabyte EP45-DS5, GA-EP45-DQ6 P45, MSI P45 Platinum and X48C PLATINUM. clear cmos button on the back panel would be a big plus. so which of these will get me higher overclock? the rampage extreme allows for ddr3 and crossfire x and the rampage formula is straight ddr2 up to 9600 in oc modes. i'm so glad i spent the extra money on the rampage formula but i have my sights on the extreme version...by early next year this rig will be full blown extreme...experience has taught me not to settle for second best...go all the way on first time out and you'll thank yourself later on...!!
