AMD has done a great job at getting the word out that Phenom II is a new and improved processor, but how do these new Phenom II processors overclock with extreme cooling? AMD showed us that the temperature bug is long gone by running a AMD Phenom II X4 processor at 1.95V and at below -190C, but what can we pull off on our own test bench? This weekend we purchased ten pounds of dry ice along with some Acetone to see what we could get a pair of Phenom II socket AM3 processors could do on the ASUS M4A79T Deluxe motherboard.
"The AMD Phenom II X3 720 Black Edition processor overclocked much better with Dry Ice cooling since the multiplier could be increased and the CPU voltage was able to go up to 1.90V in the BIOS since ASUS allows for higher voltages on the Black Edition processors. After playing around with the HT reference clock frequency and multiplier we managed to reach 4590MHz from the 2800MHz processor. This is 200MHz shy of a 2GHz overclock and is what we expect from Dry Ice cooling..."
