im looking to upgrade from an i5-520m but unsure to which i7 i can put in my system as the motherboard is unknown to speccy. chipset is QM57.

Assuming this is a laptop, upgrades are tricky without knowing what the BIOS actually supports. Are you positive you have the socketed version (988, not 989) and not the BGA version?

Honestly, the gains just aren't huge here. I certainly wouldn't to bet on a BIOS support for the i7-640m, which leaves an i7-620m as your best target. Problem is, it's not that much better. The Westmere i7s and i5s were all two core/four thread CPUs and they all had turbo. You'd essentially be cracking open the laptop and swapping in a CPU for a couple hundred MHz. And there's no guarantee that your BIOS will support this anyway.

i also found this post but im not sure if its true. (
Socket PGA988A(G1) and socket PGA988B(G2) are different, you can not mix the 2. But there is a socket (PGA989) that is capable of taking both G1 and G2 CPU's, if your laptop is using that socket there is a chance it could work but only if the bios is set up to support it. )

You will need the make and model of the laptop. The socket, bios, chipset, and cpu all have to be compatible for an upgrade.
