    Thumbs up [SOLVED] 3.4 GHz CPU runs at Core Speed: 2800.0

    Hey so, here's a fun question. Just upgraded my IBM x226 from a 2.8GHz to a 3.4GHz processor. I'll be adding a second 3.4GHz as soon as I can get a VRM for the server installed.

    Anyway, just happened to open CPU-Z, is this normal? Haha! Something doesn't look right but maybe it's just me. BIOS is latest version.



    Thanks!

    Could be that some sort of powersaving is at work, throttling the processor back until it is needed. Maybe try running some sort of intense application while CPU-z is open and see what happens?

    Wow, don't even know why I didn't think of that. Just started up CPU-Z and ran some processes, the processor is almost always at 2800.1 except for when I ran some heavy PHP scripts and the processor core jumped to 3400.0. System performed great, then went back down to 2800.0.

    Looks like that's it! Thanks!!!

    Just FYI the feature in your BIOS that does this is called SpeedStep. Turning that off locks the multiplier at max otherwise its dynamic.

    Ah that makes sense. Thank you very much! Is there any benefit to having the core at full all the time by disabling SpeedStep? Or is it safe to keep down for power saving [I assume that's what it's doing]?

    Power saving is all, that would be the only need to keep it at 2.8GHz
