I have OCed my AMD 555 BE to 4Ghz which boots into windows but still have to test it out. Just wondering what do you think? I will be trying more options but id love to get the clock higher Name: NotoriousAI Processor: AMD 555 BE Clock: 4000Mhz Mobo: Asus M4N78-SE Voltage: 1.504v (can only add 50, 100, 150 voltage so yeh). Cooler: Arctic Cooler Freezer Pro 7 Screenshot LINK: http://img834.imageshack.us/img834/9300/oc1w.jpg Valid CPU-Z link: http://valid.canardpc.com/show_oc.php?id=1973607 This is first overclock that is stable @ 4Ghz, normally I am at 3.6 to 3.8 Ghz but il try to push it today to higher. The vcore is quite high as well.... Too hot? I think the Voltage is tad bit too high.
