oops, I lied....hit 36C underload about 2 minutes ago....springtime is coming....ha
This overclock is good for this CPU Quet. I forgot to mention, that unfortunately I don't have a C1 P4 either, so it's good. From my experience, it seems that the better overclocked cpu's land just after a new core. You're catching the core at a time when it's meant to scale for some time, so there's always head room. As you approach the cores limit, or when it approaches time for a core revision, the overclock isn't as easy. There are exceptions to every rule of course, but for the most part this is what I've seen.
Good luck with your hunt man!
