The original Geekbench score with 2 x quad-core 2.26 GHz

a pair of X5680s secondhand off ebay

 

cleaning stuff, thermal bits and a long 3mm hex driver

 

Processor board comes out

 

heatsink comes off leaving some goo behind

 

nice shiny heatsink

 

fan connector clipped

 

thermal pad attached to voltage regulators

 

shiny new CPU leaves the cosy safety of it’s anti-static bag

 

and gets smeared with thermal paste

 

and then placed in motherboard

 

the tricky bit is tightening the screws on the heatsink but it all went very smoothly and now there are 2 x hex-core 3.3Ghz chips…

 

which are TWICE as fast… happy days.
