How to Overclock I5 4670k

On a good motherboard with good aftermarket cooling, most 4670k CPUs will do 4.3-4.4 without excessive core voltage. Overclocking your i5-4670k/4690k is easy with this guide. The processor is an Intel Core i5 4670K. (3.4 GHz). In 2014, I overclocked the CPU to 4.3 GHz using the MSI BIOS software’s built-in selection. How much would you spend on a new cooler? I’m sure there are videos on how to overclock on YouTube, and I’m sure there are ones on your specific CPU. CPUs are becoming more and more taxed as games and applications become more demanding.

Clear Analysis Guide Steps | How to Overclock I5 4670k

CPUs are becoming more and more taxed as games and applications become more demanding. The most popular Core is the i5 4670K processor of all time and struggles with the most recent gaming titles of 2021. Modern games rely more on CPU threads, and older CPUs like the 4670K can’t handle stable frame rates in this situation. If you don’t want to get rid of your old CPU, you can overclock your 4670K CPU to play games at 1440p settings.

How to Overclock I5 4670k

The Intel Core i5 4670K is a somewhat ancient gaming processor, having been released in June 2013. It’s a four-core processor that doesn’t support hyper-threading. It features a boost clock of up to 3.8 GHz right out of the box. Because it is a K-series CPU, the 4670K can be securely overclocked to 4.2 GHz. You don’t even need to buy pricey liquid coolers to accomplish this. In this situation, a CPU air cooler for under $50 would be far superior.

Different Steps to Overclock I5 4670k

  1. One of the advantages of Intel Haswell CPUs is that they may be overclocked for increased performance. However, you must first update the most recent BIOS for your motherboard. After the installation, go to BIOS and do the following:
  • CMOS should be cleared.
  • CPU Multiplier should be set to 44.
  • Set the vCore Voltage on the CPU to 1.25V.
  • Set the voltage of VCCIN to 1.9V.
  • Set the memory voltage to 1.5V and the ram speed to 1333MHz.
  • After that, use IETU to boot and stress testing CPU (Intel Extreme Tuning Utility).
  1. It’s one of the most effective techniques to make sure everything is working properly so far. To keep track of your CPU’s stability, use Cinebench or XTU benchmark tests. If you pass more than three tests, your processor is steady. However, you must set your Vcore mode to manual for these testing.
  2. We suggest doing stress testing for at least 8 hours while overclocking your i5 4670K CPU. The following are some considerations to keep in mind:
  • Increase the voltage if your machine has crashed. When your system has stabilized, it’s time to lower the voltage once more.
  • If you want to overclock your 4670K CPU to 4.4 GHz, you shouldn’t use more than 1.32V of voltage.
  • The voltage should be set between 1.2 and 1.32 volts.
  • To obtain a higher clock speed, we strongly advise you not to set your voltage to 1.5V. You will lose your processor if you do this.
  • Ensure that the CPU temperature does not exceed 85 to 90 degrees Fahrenheit.

CPU Stability Criteria

As a result, we generally follow the 1:1 ratio formula. Because not all CPUs follow this criterion when it comes to overclocking, determining ring bus stability for a CPU is a time-consuming operation.

  • The first step is to set your ring bus to 44 degrees (in this case we want to achieve a clock speed of 4.4GHz).
  • VCCIN should be set to 1.9V.
  • Now you can set the CPU ring voltage to the CPU voltage that you find stable (for example at 4.4 GHz a CPU may be stable at 1.28V).
  • As a result, we can adjust the ring voltage of our CPU to 1.28V.

Overclock Set Up

It’s time to boot and stress testing CPU now that you’ve set up all of the parameters. If you notice any instability, reduce the VCCIN voltage to achieve stable results. It’s best to start with lower voltages, such as 1.75V to 178V.

If you’re still having trouble finding stability, try increasing the VCCIN voltage in 0.001 increments until you achieve the results you want.

We’ve determined the best ring bus voltage values thus far.

  • CPU: 4.4GHz @ 1.23V
  • Cpu Ring Bus 4400MHz @ 1.22V
  • VCCIN is 1.9 volts.

Voltage Recommendations

  • 0.1 to 1.3V: If you are more troubled with heat issues, we recommend setting the voltage to 1.3V. To deal with the growing temperatures at this voltage, you can use any low-cost air cooler.
  • Yes, 1.3 to 1.44V is still a safe operating range for your CPU. However, maintaining low temperatures at this level will necessitate the use of a high-quality CPU cooler.
  • Over 1.45V: We don’t recommend pushing your 4670K CPU’s limitations beyond this point. You will be exposed to extreme heat, which will involve the use of a costly liquid cooler.


Lastly, this is how you may safely overclock your i5 4670K processor. Keep in mind that overclocking is all about finding the appropriate CPU frequency. Lower frequencies require less voltage and aid in maintaining a comfortable temperature. To achieve steady overclocking results, we recommend starting with a lower VCCIN and ring bus voltage.

Frequently Asked Questions (FAQs)

Can you overclock i5 10400F?

The i5-10400F, which costs $160, is a direct replacement for this processor. The Core i5-10400F is a “locked” processor which means you can’t use the base-clock multiplier to overclock it.

Is Intel Core i5 4670K good for gaming?

Sometimes excellent gaming CPUs, such as the Intel Core i5 4670K, can stifle a gaming PC more than you might imagine. Upgrading your 4670K CPU to a more contemporary model can make a significant difference, especially in games that require many threads.

How do I overclock i5?

  • Go through the BIOS.
  • Activate XMP to have your memory modules automatically configured to run at the advertised speed.
  • Set the multiplier on the CPU to the desired overclock.
  • Just choose the option to synchronize all cores for the CPU core ratio so that all the processor’s cores are overclocked to the same frequency.
