Overclocking this CPU is not news at all, but I have some interesting things about the CPU voltage settings of the mainboard to share. My mb is a 2thMax EP-MVP4G socket 7, that is not a common one in US, but the brand is a popular one here. I have overclocked to 420 by 4x105 and 427 by 4.5x95 without rising voltage (2.4V). But no luck for 450, so I need to increase voltage. Interesting things is the menu only list 1.8, 2.0, 2.1, 2.2, 2.3, 2.4, 2.8, 2.9, and 3.2V. So what can I do, jump to 2.8V?
I search for the menus of similar mb, most of them give similar data. Only one of them having 4 voltage jumpers gives the listing from 2.0 to 3.5, but mine has 5 switches. Then another one with 5 jumpers said 5th jumper is reserved and 1st jumper means 0.1V, 2nd means 0.2V, 3rd means 0.4V and 4th means 0.8V (of course when they are combine with other jumpers). I guess they have the same pattern, 1+3 = 2.5V, 2+3 = 2.6V, 1+2+3=2.7V. Now I am running on 2.5V with 450 by 4.5x100. Probably will try higher clock speed later. ^_^
One small problem is sudden dropping of CPU voltage from 2.5 to 2.4V in last trial and I have to reboot. May have to run on 2.6V. :p
