Overclocking 3570k Noob

[Jonnibravo]

Hi All,

Decided to overclock my 3570k with h100i AIO using gigabytes motherbaord profiler. I upped the cores from the standard 3.4ghz to 42 or 4.2ghz and I'm getting idle temps of about 34-41, after running prime stress test I am seeing max temps of 60c after 5 mins.

Are these ok values and would it be sensible to stick at that for a 24/7 overclock or is there more play in it.

Also oddly windows 10 is showing CPU running at 5.13ghz???

Those temps are fine. Up to 75c under artificial stress testing is okay for 24/7 in my books. Gives you some head room for dust accumulation. There are two important things you didn't discuss which are
A) volts. Ideally you will stay below 1.35v for 24/7 use. You didn't mention whether you let the motherboard decide or whether you set it manually (keep in mind also that the motherboard may over compensate for v droop under load so use cpuz to see what volts you're actually running under load. Remember, lower volts means lower power consumption and heat so long as you're stable.

B) stability! You mentioned your temps after 5 mins of testing. To get a feel for your load temps you want to run for about 30 mins to saturate the cooler and see what your break even temps are. Also, 5 mins is only really enough to see if your system is really unstable. I'm not one of those guys that advocates 24hr prime runs, but 30 mins is a good way to eyeball it. After that I would suggest just running the most intensive games/programs you have to make sure it's stable in real world testing.

4.2ghz is a very respectable overclock, so if you aren't bottlenecked then leave it and keep the extra stretch for when you need it in a year or two. But if your volts and temps are safe you can always shoot for the stars. 4.5ghz is often achievable on those chips, but the closer you get to the limit of the chip the lower the returns are for the extra volts and heat.

Ignore windows 10 reporting that it does it a lot.. use CPU-Z or something like that. also what voltage are you using for those clocks? thats the main importance. keep temps under 80c to be ideal most of these chips can get to 4.4 with ease.

i built a 3570k/asus p8z68-v gen3 pc last night.

Overclocked to 4.2 and then 4.5ghz without any bsod, seems almost too good to be true....

I used an offset overclock, idles at 0.9v ish and under load at 1.216v, +0.005v - it seems too low, looking online everyone seems to be about 1.3v vcore???

I was using coretemp and openHWmonitor and intelburntest.
