Need help OCing my i5 3570k

post #1 of 4
Thread Starter 
Setup:
Mobo - msi Z77A-G41
GPU - PNY GTX 660
CPU - i5 3570k
Power Supply - TR2 600W

My stock cup runs at 3.5 ghz and I would love to see some better performance out of it. However, I am very protective of my PC because I love using it. I don't trust myself enough to over clocking it by myself, so I'm wondering if anybody can give me screen shots of their settings for a stable 4.0 - 4.2 ghz setup with as little volts as possible. I would appreciate this very much, thank you smile.gif

what cpu cooler do you have?

thermaltake power supplies are on the poor side
but the tr2 600 is enough for the lower power build

if its the stock cpu cooler, keep it at stock speeds

Welcome to OCN! thumb.gif

You'll probably even be able to hit 4.0 GHz on the default/stock voltages. (If you're lucky)

By the way. All CPU's overclock differently. The voltage will definitely vary on chip to chip (even if the same model).

e.g 4.0 GHz, one cpu may require 1.22v, the other CPU may require 1.25v to be stable. Also you need to be careful that other motherboard manufacturers, e.g asus and gigabyte have different namings (even though they do the same thing across other motherboards) for the BIOS settings.

Important: I suggest you read the Ivy Bridge Overclocking Guide when planning to overclock your CPU.

Link: Ivy Bridge Overclocking Guide (With LN2 guide at the end)
Note, these are programs you should use when overclocking:

For CPU Temperature monitoring: RealTemp
For stress testing the CPU: Prime95

You should keep the temperatures under 80°C for long-term 24/7 use. Use a medium Load Line Calibration such as medium/50%. Use Intel Enhanced Speedstep Technology. Use Intel C-States if you want but, it can cause instability (Not really sure). You can overclock via Intel Turbo/Boost clock or the usual changing the core multiplier.

Always keep the BLCK (Base Clock): to 100.00 MHz. Altering this setting can cause instability and can even damage hardware.

Check the Windows Event Logs for WHEA errors. These will tell you if your CPU overclock is unstable.
You can access the event logs via typing "Event Logs" in the start menu search bar. Make sure you look under the system tab for the errors.
Also refer to this link for bluescreen codes (These are very useful to seeing what is causing your overclock to be unstable): Bluescreen of Death error code list for overclocking

If you are not using a stock cooler and are using a decent aftermarket cooler, I'd say head around 4.2 to 4.7 GHz (Depending on how much voltage your CPU requires at certain overclocks).

Note: Make sure you start off using a manual voltage for your CPU overclock. Using a adaptive or offset for the CPU voltage can be a lot more tricky to find the sweet spot for the CPU voltage and stability.

First find the lowest stable voltage for your desired CPU overclock, then work out on the adaptive or offset voltage. (I do recommend taking a look at one of the overclocking threads before doing so).

i had a 3570k and got it to 4.5ghz with like +.125 offset voltage.

you shouldnt have any problem, in my opinion, with 4.2ghz at stock voltage with the stock cooler.

if you upgrade the cooling i recommend that real popular noctua going around. if you have room in your case lol. i went with the corsair h110 hydro series water cooling closed loop though.
