    I currently have the m15x with a i7 740qm and will be upgrading to the 920 or 940xm but worried about all this throttling issue.

    My system is equiped with:-

    4GB ram
    Radeon 5850
    Bios A09
    9 cell battery (but i always use the mains)

    I'm happy with my 740qm for now but i may need more power in the future. Will the 920xm or 940xm work properly on it's own with no software to help it from throttling?

    No problem at all. Check here if you want to see it. The Rev just made a nice run to prove it for someone else.

    With BIOS A09, 920/940XM will work without throttling.

    Thanks for that.

    Can anyone else confirm who has one with similar specs to mine.

    Quick question - I have a 940mx on the way to replace my 720QM. Am running the 64 bit Win 7 that came on the laptop - no problems. With the change in processor, what is the likelihood that Windows will decide it is on a different machine and invalidate the install. I have had occasional issues with a processor/mobo install on my desktop - wound up having to call Msoft and explain that it was the same machine.

    Thanks,

    Joe

    Slim to nil Jdpurvis. I highly doubt that you'll have any trouble installing new hardware, it should just be plug-in-play. If you have any issues at all, I'd be extremely surprised.

    It's plug and play, no problem at all. With a good preparation it's really an easy job. Make sure you have some thermal paste around and something to clean the old paste from the heatsink. ESD-protection is recommended.

    Btw, 600x900, nice screen :D

    Oops! - fixed the typo. I've got a fresh packet of MX3, and stuff to clean the old paste off - I've been playing with throttlestop to learn about it, though not needed for the 720Q. Am expecting a big bump in performance.
