Problem with Dual Core
October 9th, 2021
I am using fujitsu-siemens notebook with core2 duo t5450 .
I have been running Cpu-z on it to check its performance .
While checking the results i have noticed that one of the cores seems to be inactivated .
Let me show you :
SS of the the Activated Core : core1 1662.5 mhz
SS of the inactivated Core :core2 1.0 mhz
Plz guide me
What motherboard do u have?
BIOS version?
cool feature called speedstep
when the processor detects that it isnt under heavy load, it steps the core speed down, in some cases disabling a whole core to save power.
