    I am thinking to replace the i5-2430M of my Aspire 7750G with an i7-3612QM (or QE) i wonder if the CPU is compatible with the board/chipset ?

    Thanks

    Short answer - no. You have Sandy Bridge based laptop so you have to look for i7 2xxxqm series cpu.

    A i7 2960xm or i7 2920xm is better than 3612qm.
    Also if you use intel extreme tuning utility you can clock the CPU higher.
    Of cause it depends on you laptop and cooling. But it can run at 4.0 GHz stable and if the cooling is good enough you can get it up to 4.6 ghz.

    Thanks.
    I thought i should consider only 35W CPUs.(Factory installed CPU is i5-2430M) Maybe 45W ones are not a problem for the factory cooler and PSU to handle without any issues?

    Can't tell exactly. But I would consider a 2860qm instead of the XM once.
    The reason is you only have a 90watt PSU.
    I could find a Aspire 7750G with a factory installed i7 2670qm rated 45w.
    So it won't be an issue with a 2860qm, just be sure to get some high quality thermal paste or liquid metal.
    I prefer thermal grizzly hydronaut.

    just in case that you know, is it certain that 3612QM won't work on Acer 7750G board ? i know its ivy bridge but saw some reports some people installed ivy CPUs on HM65 boards - The thing is i can get the 3612QM for 65 euros and its 35W, while 2760M, 2820QM, are around 90-100 euros and 2860QM 130+ euros . And the performances are similar enough i think

    I read once somewhere that adding support for Ivy Bridge on 6x chipset required rewriting bios almost entirely cos bios for sandy bridge had different structure or something. For this reason it was never done by laptop manufactures. I saw that only on server boards. But I might be wrong and might be single cases i laptops too.
    When I checked bios release notes for 7750g, there are only talking about Sandy Bridge microcodes 206A7.
