I havent done the heatpipe mod but I do have a 120mm fan on high directly facinf the pipes and NB.
Max MCH is 1.72 and ichio is 2.volts. Isnt that going to cook something? Temps should be OK but thats a LOT of v through the mch and whatever that other thing is.

Or just start messing with the volts till it stabalizes?

What settings exactly would you start with and mem timings as well maybe loosen them and drop the multiplier to 8 or just play with voltages.

Also what would cause it to just shut off!

BTW I havent played with the ichio 1.5 at all its still at stock settings of 1.5. What does it do?
