    Question about Santa Rosa platform...

    I stumbled across an article on wiki about the Core 2 Duo and the Santa Rosa platform.

    They seem to list all of the platform's features, however i'm wondering if some of them really work. For example, wiki states that : "When a single threaded application is running the CPU can turn off one of the CPU cores and overclock the active core. In this way the CPU maintains the same Thermal Profile as it would when both cores are active."
    Does this really happen or did it not make the "final cut" of the platform?

    I've seen my T7300 rev up to 2200 Mhz for a few seconds TBH and RMClock does tell me that the CPU's maximum multiplier is 11x (200x11 = 2200), however i couldn't test if indeed it works at that frequency as the CPU seems to completely ignore what RMClock "tells it" (i managed to get it working on my AMD machie just fine, but the C2D seems more...resilient :D )

    I'm sorry if i posted in the wrong forum, but i didn't know where to put this...

    It's called IDA (Intel Dynamic Acceleration) and IMO it's not working very well. Because how often is the other core COMPLETELY idle? Almost never! It almost never kicks in... there are always some windows services occupying the core

    What about the processor revving up to 2200 Mhz sometimes?

    Well since a T7300 is rated at 2200Mhz (2.2Ghz) this has nothing to do with IDA it has to do with the Intel "power saving" feature, I don't know what they call it used to be "speed step" if you saw the IDA kicking in you would see something like 2.3Ghz in one core. So any way what is the question? Oh yea does it work? Don't know but with what OP said they have never seen it. Don't confuse battery saving features (SS) with performance (IDA).
