Hallo!

I have an Acer aspire 5745dg with a g1 Intel socket that has the Intel core i5 450m with max mhz 2.73 that CPU is a 2 core and 4 threads and runes with 35 w of power I would like to upgrade to an Intel core i7 840qm with Max mhz 3.2 that also is a 4 core 8 thread CPU that uses the same socket but it works with 45 w of power. I am concerned for the motherboard if it will be able to support a 45w CPU. Can I do this upgrade or no ?

    The designated Socket G1 i5-450M cpu compatibility list, do not have the i7-840QM cpu as a compatible upgrade, the most powerful cpu that Acer fitted to the Aspire 5745DG was the Core i7-640M cpu that will give you a relative performance increase of 20% to the i5-450M cpu. The Socket G1 - i7-840QM cpu should fit into the cpu slot and could work, but it will run hotter as this cpu has a TDP of 45W and it could decrease performance from the Aspire 5745DG laptop compared to what Acer tested your laptops mainboard with the i7-640 cpu, so be aware of this, as just fitting a more powerful cpu doesn't mean better performance.

    Upgrade your Aspire 5745DG to the i7-640 cpu with more ram and up to its max 16GB into its 4x ram slots at 4x 4GB DDR3-1333Mhz type ram and install a 2.5" SSD boot drive as the combination of all these upgrades will increase your laptops performance by at least 200%. Good luck and hope this helps you out.
