CPU compatibility ivy and sandy bridge

Solution
Ivy Bridge requires a BIOS update to work on Sandy Bridge chipsets, both for the microcode and to program the VRM. Infamously, boards OEM by Intel were never provided with newer BIOSes because Intel wanted you to buy a newer chipset and board from them.

While the link shows it's not a supported configuration, Lenovo boards were usually OEM by ECS which did provide updates. So unless you can find some report online that it works, the only way to find out is to flash the latest BIOS and then try it.
Check with Lenovo to make sure you get the right bios and update it before changing the CPU. Depending on your motherboard, you should be able to.

You need to go to Lenovo's website and look up your model number with your correct motherboard (9HKT43AUS) and see if they have the correct bios for it.

The 'Processor' section is the list of officially supported CPUs by those computers. Unless you can find specific information that says otherwise, I'd get the i7 2600 rather than the Ivy Bridge CPU. It's not like there's a radical difference in performance between the two.
