Dual E5-2660 wrong CB R15 result

Hello! I swapped my cpus today, i put 2 E5-2660 in my “OLD” workstation, it had 2xE5-2690 before but i will put them i a new build. Now to the funny thing. After CPU change i ran a R15 benchmark just for the LOLs and to my surprise the score was as high as before.

ca 2300 cb , thats around the score i had on the system whit the E5-2690…

task manager shows 3.54GHz under max load…


It also reports 2.9GHz… And still E5-2690…

PAssmark score of 20931…

What is going on? Why is windows showing wrong cpu, speed… And why do Passmark and Cinebench report so high numbers?
