Re: Upgrade CPU on ThinkCentre Edge 71

Propably I'll buy i7-2600S and exchange my existing G840 2.80GHz.

According to:

http://www.lenovo.com/shop/emea/content/pdf/desktops/thinkcentre/edge-71/en/EDGE71_DS_EN.pdf

it should be OK and I hope the power supply can manage it.

 

 

BTW do I need another CPU heatsink for i7-2600S, or I can use the same from G840?

Knows anyone if i7-2600S will work with an original Lenovo mainboard, I mean will the BIOS support it?
