    XTU works amazing...but don't forget to enable overclocking and overriding the turbo settings in your bios

    I've never heard of this XTU program before today - will it do anything for my 740qm? Or is it Sandy Bridge only?

    It could do something depending on bios support, won't hurt to test it out.

    ya, llike moral said, it really depends on your bios. I believe the bios on your lenovo is locked down, meaning it won't allow any overclocking, but i'm not 100% sure if there is an unlocked bios or something else that you can try.

    If the bios allows, XTU will work. You can overclock your FSB with XTU.

    if XTU doesn't work, you can still overclock the 740 with SETFSB

    I was wondering to ES and QS models have unlocked multiplier for the CPU?

    If so, can overclocking of the CPU be done via software instead of BIOS?

    Software ocing requires an unlocked bios with sandy bridge.

    2720QM ES is locked, I think some 2820 ES and of course the 2920 ES are unlocked.

    mine does this as well ; /
    So does this mean my 2720es is slower than a 2630qm...?


    EDIT: Yes, my friend's 2630qm gets 6800 pts in passmark.

    I'm planning to get a 2720QM ES. May I know if it will work on my HP Elitebook notebook with i5 2540M. Does HP BIOS recognize ES CPUs?

    The bios isn't an issue with ES chips. Most ES chips function similar to their OEM counterparts. Since your EliteBook support Sandy Bridge processors, it will work fine. But, the 2720QM is a 45 watt chip, and the 8460p can barely keep an i5 cool. I'd stick with dual core i5 or i7 only.

    Here's a CPU re-paste guide I made: http://forum.notebookreview.com/hp-...p-elitebook-8460p-cpu-gpu-re-paste-guide.html

    I have a choice to get 2720QM ES and 2670QM OEM version at similiar price. Is it worth to take the risk for extra 200mhz turbo clock and 2MB L2 cache? I believe my 8460P can handle quad cores because some 8460Qs come with quads and they both share the same cooling solution.

    Does you 8460P have the AMD graphics card? If it doesn't, then your laptop can handle the quad. Otherwise, no. I'd get the 2670QM, since ES processors can be buggy.

    Mine comes with with AMD GPU. How much hotter will the quad be? Mine currently idles at around 45C and peak at 70-80C. I don't think temperature will be a problem and I have notebook cooler if needed. I just feel dual core is a bit laggy because I multitask alot and getting quad for future proof.

    My 8460p with the i5 and AMD graphics, hit 100C in Prime95.

    I suggest you run Prime95 and monitor the temps with HWMonitor. If it gets over 90C, the quad will run too hot.

    I tested mine and it maxed out at around 90C. I have reapplied the thermal paste before. Idling at around 45 to 50C. Now is winter and I think that helps to lower down temperature.

    In 8460p with ATI graphics i5 was replace by i7-2720QM ES, BIOS F.27, system booting, load windows (I hear greeting sound), but graphics card doesn't initializing (in BIOS and in windows mode). All other working (sound, keyboard). How can I modified BIOS (move CPU microcode or change init graphics from internal i7 HD3000 to ATI 6470)?

    Question, has anyone been able to confirm that the Q154 is unlocked or not?
