    So I was reading up on the PB's CPU and all the documentation I found said it is capable of up to 2ghz. So couldn't RIM just update our PB's to 1.5ghz theoretically? I'm not to tech savvy whith Tablet hardware but on my PC I can set the CPU speed to whatever I want. Is that ability completely locked down by RIM?

    That would be a nice gift to those of us that are loyal Not that it would ever happen lol

    The actual chip is not a "Cortex-A9", however. It's a Texas Instruments OMAP 4430: OMAP - Wikipedia, the free encyclopedia See also ARM Cortex-A9 MPCore - Wikipedia, the free encyclopedia

    The way the ARM chips work, the design of the chip is by a company called ARM Holdings, who don't actually make chips. They basically write the software that defines how the chip works, and license that design to companies that actually build chips with it.

    That design is capable of being pushed to 2GHz, by their calculations, but Texas Instruments hasn't done that with the 4430.

    No, Cortex A9 it just a reference design from ARM. Other company like TI, Samsung, Apple license the desgin and make their own SoC.

    The clockrate of CPU/GPU/RAM in SoC depends on how much heat and power, other components, baterry life, etc.... and fab technology (45nm, 28nm,...)

    While it is true when a company release a SoC with a X stability clockrate but the tablet manufacturer decide to underclock the SoC to save battery life, it is not the case with OMAP 4430 in the Playbook.

    This. The CPU design in the PlayBook is capable of being used in CPUs up to 2GHz. The actual CPU chip inside the PlayBook is only capable up to 1GHz.

    I would never do it on mine, but it would be cool if someone could figure out how to overclock it and see what it could do.

    Actually the TI OMAP 4430 can go up to 1.2 GHz. The 4460 has a recommend clock speed of 1.2 GHz to 1.5 GHz.

    Are you basing that on the unverified information in Wikipedia, or do you have another source for it? Texas Instruments' site says only 1GHz.

    All CPU's can be overclocked. I would not be surprised to see it go up to 1.5.

    I'm well aware (though I think 1.5GHz is out of the question) but it's not my question.

    I merely wanted to know if he'd found a reliable source or was just repeating what we could all see on the Wikipedia page I linked to...

    Actually yes, some others were able to do this, here's just one of them

    With news of the 4g lte playbook being released very soon, numbers have been leaked and it seems the new playbook will be clocked at 1.5ghz.

    Surely the overclock could be applied through an OS update.

    Id much welcome a speed boost

    In the PB Browser go to
    "Browser Settings"
    "Content"
    & swith off "Enable JavaScript"

    It makes a world of difference, speed wise.

    javascript wont work anymore
    many pages rely on it for menu or navigation stuff...

    about overclocking, as far as i know most arm device can be overclocked fairly eady and if its to much the device just crashes. its almost impossible to do some real damage to a arm cpu with a bit of overclocking.

    i wouldnt mind to have a option for this but i doubt rim will allow something like this in the future. maybe its possible with rooting the device but this isnt possible anymore too
