HELP! Bios shows CPU running faster than designed, is this possible?
Last response: in Systems
Hi. I have just completed a new build PC, no Windows 7 installed as of yet.
The processor is an i5 3470 3.2GHZ 6mb Cache, Memory 8GB 1600, MB Gigabite Z77-DS3H, 90GB SDD.
When i loaded up BIOS for the first time, it shows my CPU to be running at "3428 mhz". (might have been "3628 mhz"), but the processor is only stated to be a 3.2ghz...?![:o]( ":o")
I read that 1000mhz is 1ghz, so why does BIOS show my CPU to be running at 3428mhz... this equates to 3.4ghz (might have been 3.6ghz) doesnt it? How is this possible?![:pt1cable:]( ":pt1cable:")
Has my MB overclocked my CPU automatically? Surely it should read; 3200mhz (being 3.2ghz)... im worried its going to burn out, or its stuck in 'turbo mode or something'... (which apparently is 3.6ghz)
Anyone shed any light on this?
Thanks!
Tom

A computer will run a processor at full speed when initially booting. Just a wild guess, but I imagine that's what you're looking at.
Absolutely possible. Some mobos (ASUS in particular) overclocks slightly by default, probably to get better benchmarks. Either way, a non-K edition Core i5 has a few unlocked multipliers above max turbo, so running at that speed is fine. Also, the processor can dynamically turbo up to a few bins (few hundred MHZ) above the default when only 1 or 2 or 3 cores are stressed. This is by design.
