Product ReviewsAMD Phenom II X2 550 550 - 3.1GHz Dual-Core (HDZ550WFK2DGI) Processor

Not the best CPU architecture but do have great overclocking potential.

Not the best CPU architecture in the world, but it manages to get the best performance possible from an old HP DC5850 computer. They do have great overclocking potential though.

Really great.

Nice fast processor, with the odd chance that you can unlock the extra cores.Provided you have a suitable motherboard.Perfect processor for my modest needs.

time for a boost

Needed to speed up system since installing windows 10. This processor, bought second hand, has done the necessary processing speed upgrade.
