Easily. My 6 or 7 year old 3.6Ghz P4 hit 4.0 without breaking a sweat and 4.2 on air...though I never watercooled it.
Still, that's only a 12%OC from 3.6 to 4.0. My q6600 @ 9x450 (4.05Ghz) was more impressive as a 68%OC...which is just filthy. It wasn't prime95 stable though, and was only a benchmark. Unfortunately, I can't prove any of this as the screenshots are on a WD raptor which lies somewhere in my freezer...likely covered in frost by now as I'd forgotten about it. So, unless I feel the urge to get off my butt and take my gpu out of the loop, or get a bigger radiator, or both, I will have to watch this club from the outside.
Or if I swap in the OC'd P4, does that work? That wouldn't even be a challenge though...I'm sure that could hit 4.5 or so...![]()
