Max Super Pi 32M


@4638Mhz - more efficient run (2178985)



@4652Mhz - less efficient run (2184839)

Lucky I took this screen capture first, as system rebooted before I could load the other cpuz instances

Yeah it is nuts but have been waiting to late night for best/coolest ambient temps too hehe

Been prompted to try some more powerful fans... maybe squeeze out a bit more for super pi 1m hehe

maybe i should get out my ear plugs and my monster 190cfm fans



have to be careful with proximity of my ram cooler to a 190cfm delta fan or the delta will eat my ram cooler for breakfast
