Nono; if you set the CPU speed via BIOS AND disable C'n'Q feature, it is recognized properly as 3GHz part (according to cpufreq-info). But since the C'n'Q is disabled, the CPU works always at 3GHz no matter if the additional horsepower is needed or not. Since I mostly write and edit stuff, and only sometimes play games, I need that power only sometimes. That's why it bothers me ;-) If you set the CPU speed via BIOS, but DON'T disable C'n'Q, then it's recognized as 2.6GHz, no matter what you were trying to force. Maybe it's also BIOS issue (I got ASUS M2N-SLI Deluxe).
: Aye, RMClock allows to set any voltage (VID) - provided motherboard can deliver it - and multiplier (FID). Also, it allows to define any number of intermediate "states" (so depending on the CPU load it can be automatically clocked at let's say 1GHz and supplied with 1.125V, 2GHz and 1.325V, 3GHz and 1.4V, and so on). It's not needed to set the maximum multiplier in BIOS for it to work; only the C'n'Q must be enabled (and CPU drivers installed in OS, of course; they need to support throttling). I'm using it almost 5 months now and it's working perfectly, just needed to configure it a bit at the beginning. So, it's theoretically similar to cpufreq-set (and the rest of utils) - from functional point of view the only difference is that cpufreq doesn't allow me to override default max CPU speed, while RMClock does. And that's what I'm trying to change
