IBM M57

It works great now I just had to update it was a little slow at first now it works great

A bit slow before update

The product does work and after hours of work it is doing fine so far will have to see if it keeps working.

Product was not as described it was DDR2 and the Keys to activate were all rejected from Microsoft as invalid. I had windows 7 pro so installed it then upgraded to windows 10.Was. It said Microsoft certified refurbished on box that must be a miss print...
