Overclocking instructions for i5 4670k
Overclocking instructions for i5 4670k
Hello everyone,
My setup is as follows:
I5 4670k at 3.4 GHz
8G DDR3 1866
Gigabyte GA-Z87M-D3H
Noctua NH-D14
RX 580 Sapphire Nitro
I adjusted the core clock to 3.4 to 4.2, voltage from 1.067 to 1.167, temperatures between 45-60°C.
Despite these changes, my games run slower and I’m unsure why. Also, I increased the voltage slightly to 1.200V and noticed a small improvement. Could you suggest the optimal voltage range?
Also, should I consider overclocking my RAM? If so, by how much?
Are you adjusting the BIOS settings or relying on a Windows tool?
The options I see don’t match an overclock. They resemble the typical ranges found in regular turbo core performance. Usually, overclocking involves choosing one clock speed and one voltage setting permanently. There can be a range, but this is mainly handled through the advanced power profile in the control panel and Intel’s speedstep settings in BIOS—more about saving power than actual overclocking.
At maximum load, you should aim for a very tight range of maximum clock and voltage values. If you’re using a utility, consider removing those settings so I or another person can set up a full-time overclock via the BIOS, provided you have the right cooling setup, which we’ll discuss later.
I notice you have a D14 cooler and mention a 60°C temperature limit?
Do these readings reflect normal operation or are they during Prime95 stability and thermal stress tests? I assume it’s just regular use, correct?
Additionally, have you verified if your BIOS is up to date? What version of the BIOS do you currently have installed?
I am also pushing my CPU to its highest setting and it remains stable at 4.4-4.5Ghz, but I still face issues with the monitor showing the CPU frequencies are sometimes off the limit, as seen in this post. I have successfully reached 4.5Ghz at 1.23V, though occasionally the frequencies drop to around 2.5-3.9Ghz and I don't know why.
I am conducting further tests and will update you if I achieve better results.
Regarding 4.2Ghz, I have been using Ai suite 5 way optimisation so far, and it is functioning properly.

Hi everyone,
I’m asking about my setup for the i5 4670k.
Current specs: 3.4 GHz, 8G DDR3 1866, Gigabyte ga-z87m-d3h, Noctua nh-d14, RX 580 Sapphire Nitro.
I’ve overclocked it to core clock 3.4–4.2 GHz, voltage 1.067–1.167V, temps 45–60°C.
Performance is stable, but games run slower. I tried increasing voltage to 1.200V and saw a small improvement. Could you suggest the optimal voltage range?
Also, should I consider overclocking my RAM? By how much?
Thanks for the help!
