My CPU is overclocking(I haven't overclocked)

Hi all,

Just bought some new ram as I was having some instability issues and whilst running stress test the CPU(i5 3570k 3.40GHz) is running at 4.08-4.22Ghz intask manager.

I noticed in BIOS it was running at 3.8 but I though this was just the turbo feature and thought nothing of it then when I was running at idle I noticed some spikes and the machine was running at 4.12GHz.

I am on stock BIOS settings and have not altered of messd around with any settings, voltages ect so I don't understand why the cpu is overclocking which could be dangerous as I have no cooling other than stock.

What are your temperatures like?

The I5 3570K would know whether it's suitable to overclock itself and clearly it's absolutely fine. Don't complain about the free boost of performance

manually set the cpu/pci clock to 100 in the bios

(it might boost to 4ghz if one core is utilised)

At idle there running at 25-28 to 35C

Under load using prime 95 for 5 minutes 74C

Could this be why my system has been unstable Wazza

could be if its auto overclocking the bclk

it will be called cpu/pcie clock just manually type in 100 and save/exit

I find that the value shown in task manager is incredibly unreliable.

Download a program called HWinfo as this gives you a graphical representation of what speed each core of your CPU is running at and will help you identify if it is turbo boosting.

do you have some sort of OC software running, or dose your motherboard have an OC switch that is set to on.

I have reset the motherboard to optimal stock settings so it should be set to stock, I have no overclocking software installed just the chipset drivers and software from gigabyte and intel from the motherboard. :confused:

Inevitably it will be something I have touched though, I'll check the bios settings

not in bios some boards have a button to auto overclock the chip.
what model of board do you have

I have a gigabyte z77 dsh I've altered the xmp proile in the bios for the cpu and the chip is now running at 3.99 max although hwinfo says all the cores are running at 3.608 constantly when under load the cpu pci block is set to 100.00

@wazza300 no blue screens today since I changed the memory

Sounds to me like task manager is wrong then

If you go here http://www.intel.com/support/processors/corei5/sb/CS-032278.htm?wapkw=intel+core+i5-3570k you will see that on a load across 4 cores the cpu can boost up to 3.6 so I think everything is working fine. I honestly wouldn't trust task manager at all.

What does CPU-Z say?

Made me puzzled when I read the thread title.

As mentioned by others you need to verify the actual clockspeed from a reliable program, for example CPU-Z.
