I have a curiosity about Overclocking

[SoumyaHD]

Can Intel desktop CPU like 3570k can be overclocked and a non k processor be do the same ??

K is overclockable

everything else intel is pretty much not (there are a couple of strange exceptions )

it does not appear to be a unlocked model.

i have your motherboard. sucks to be us lol
it under clocks your cpu-nb and hyper transport because its a 125watt core
msi in the great wisdom they have 0.0 also overvolts it to the max safe vcore +dif on auto.

concerning to say the least for someone that buys it and does not want to touch anything that is not broken

intel's core i series' k cpus can be overclocked from 2500k to 3930k and at the top 4960x. sandy bridge-haswell core i3, pentium, celeron cannot be oc'ed using cpu clock ratio multiplier.

sb and ivb core i5 and i7 non-k cpus can be oc'ed by limited amount by changing turbo (4 bins above base clockrate) multipliers. in some motherboards, those non-k cpus can be oc'ed further using a tweak called multi core turbo/enhancement that applies top single core turbo clockrate on all 4 cores. afaik, haswell non-k i5 and i7 cpus can't be partially oc'ed anymore. however, the mce/mct settings exist in z87 motherboards. both type of oc violate warranties.
if vendors want, they can implement oc tweaks in bios e.g. asrock (or was it msi...) implemented a "non-z" o.c. setting in their non z-series chipset motherboards to oc cpus until intel pressured them into disabling it in a later bios update. another instance was in gigabyte's sniper b5 motherboard based on b85 chipset.

all of those cpus can be oc'ed by a very limited amount by changing the bclk frequency.

thanks did not know that.
so i guess it will be on what motherboard and bios it is on to accommodate

personally i would leave that core as is and mess around with your amd since it will be useful for some time as it is a 22nm core with a 3.8ghz turbo

Why we overclock a CPU , What is the main reason ?? To increase computing power ?? Performance ?? Please give a specific answer .

afaik, the main reason is the desire to find out how much more your cpu/hardware can do and how far it can be pushed. i don't think there is a specific answer. if there was, it'd be close to "curiosity".

ya, what tasking u are planning on performing would help to know.

if u don't need any performance gain you would just be lowering the life span.

now to start tho if u want a hobby for it you could disable the turbo, set vcore to turbo voltage and multiplier and not use core parking. this would in affect 'unlock' it and increase the power draw while giving little to no performance increase but is the first step of a overclock after u have proper cooling in use

 

[matt798]

well... u can oc from turbo but then u are depending on the computer to decide if u need the power but u can in most cases use the multiplier stepping technology with no performance decrease
