However the P67 used a digital PWM and your Z77 uses analog PWM even though asrock is telling you it is digital, it isn't Intersil doesn't make digital PWMs. It is a perfect senario if you can tell us which requires more vcore for the CPU OC id be interested, beucase i want to know:
How does Digital with terrible MOSFETs(P67) compare to Analog with better MOSFETs(Z77)?
Hi Sin, do any z77 boards use (real) digital PWM? How can we find that info?
Also, regarding the p67/z68 vs z77 differences debate: the z77 has the potential for higher memory speeds. In this case the Asrock boards are rated at 2133 for the p67/z68 vs 2800 for the z77 boards. There are other subtle differences like the LAN ports, and depending on Sin's info, 12+6 PWM vs 16+8 PWM...etc.
@BMWM1, could you post your rig specs in your signature section? It will make it easier for readers to get a better picture of your system and help others who are building their own.
