I have two 1700+ DLT3C's , one is a 0310XPMW (27 code) and the other is a 0319WPMW (28 code), that are going to go in my primary and secondary rig. Which do you think will oc further? My primary rig is watercooled so I don't want to test them both if I dont' have to. I'm guessing that they'll both max out around the same. I've read that the XPMW's can get a higher oc but require more voltage to do so. But on the other hand....the the WPMW is 9 weeks newer....
