CPU Overclocking

[Dr.J]

Hi Peeps,

 

Just a quick question, why does CPU-Z say that my CPU is running at 3.5GHz when task manager is telling me its running at 4.5GHz? Ive overclocked it to 4.6 so why is CPU-Z lying to me

 

Cheers,

 

Jamie

cpu z is right I have no clue what winows does but it does the same thing for me just pay attention to cpu-z it reads directly from hardware...

did you set all 4 cores to 4.5?

[Dr.J]

Task manager said it was running at the stock speeds before though....ive gone into the bios and change the bits and bobs and now task manager is looking correct but CPU-Z didnt change..and yeah

windows 8 task manager is a POS and you should never look at it

it is always wrong

 

3.5GHz is the base clock on the CPU, which both task manager and CPUZ show is right

Looks like speedstep issue to me, did you disable it in BIOS?  CPU-Z is reading it correctly(look at your multiplier / 16-46). 46x100mhz = 4.6ghz

This is what i have set

I don't recommend disabling speedstep, it does it's job. and does it well. However, if you don't like it for whatever reason, make sure your power-saving settings within OS are set to always on/max performance. And you can check your BIOS for your CPU EIST function...that is essentially speedstep. Just to clarify though, your PC is operating as it should be, and your 4.6 Ghz speed is active.
