    That is stable for me still in testing. Mflops at 5.1 to 5.3 that's about a 130% increase from stock.

    any idea if when the kernel will be stable enough 4 release. pm if you are ever in any need of beta testers. lol im lookin to go more in depth with this phone

    so will we have oc before 2.2? and its running at 787mhz

    And stable and cool. That would be a yes. The palm pixi shares the same processor as ally as the pre is different. I believe I'm the first in the world to OC a msm7627 stable.

    That would be my reason for overclocking my Ally. I'd like it to be a bit snappier when loaded, but to save battery life, it could step back to 400mhz or so when it's idle.

    ^^^^^ yea definitely, if your willing to release a beta of the kernel, i would be glad to test drive it and report my findings. PLEASE, I NEED TO DO SOMETHING WITH MY ALLY LOL

    you will become a hero well at least for me you will, and yes its kinda sad but ill get over it.

    So what is the Allys Stock Clock and what is this OC?
     
  12. cb3p0

    cb3p0 Member

    the stock clock is maxed at 600mhz. overclocking it would increase the speed at which normal operations function.

    i should have higher goals in life lol

    No i mean what is it overclocked to?

    if to is do it makes ur phone run faster
     
  16. Mitchell4500

    No... I mean what is the MHZ this kernel is clocked at...
     
  17. gregskeels

    gregskeels Member

    i guess around 787mhz like drellisdee shows in the pic?
     
  18. Oh, well then

    Seriously though, that's awesome. You must be omnipotent, as well.
     
  19. The default is 600, but Drellisdee clocked it to 787. Not a lot, but certainly a good amount.

    upper limit will be 800MHz, stable. True for the same chipset in the pre. While I have seen a few moto droids at speeds higher than this, the lack of a dedicated gpu in the ally is a real hindrance to any sort of significant speed increase.

    But,if overclocking can be made stable hardware-wise, then an OC'd CPU on 2.2 will be even better.
    JL
     
  22. Actually the Ally's processor is slightly different from the pre, according to Drellisdee. But if it was the same, we'd probably be able to get it to 1GHz or higher. The guys working on the Pre have gotten it to 1GHz, and are working on getting it even higher.

    Our processor & Palm Pixi MSM7627

    Our device spec sheet VS740

    Palm Pre has OMAP 3430

    Here is the freq table I'm using currently.

    5.     { 0, 120000, ACPU_PLL_0, 4, 7,  60000, 1, 3,  61440 },

    20.     { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, {0, 0, 0}, {0, 0, 0} }
    21. };
    22.  
    The 6th column is the AHB bus which has a max khz of 200000 on msm7x27 models. The 7th column is the ahb divider which is (x + 1) which the highest value allowed is (3 + 1) =4 so its Clock speed 806400/4 = 201600. So the highest clock speed without pushing the ahb over its max is 787200.

    Also a good read is Overclocking 101 Read the part about the wafers on the chips construction. That is why the max speed your processor can handle is different amongst the same models as its due to construction quality.

    So is there anyway we could try it out?

    There is actually a *stable* 1GHz Pre kernel.

    Ah, I see. Interesting...
