AMD 5900X Fails To Reach Boost Clock: 3 Easy Fixes

Overclocking a processor isn’t always a sweet ride. Depending on your PC setup, there can be many problems. Some common issues can be temperature, ram speed, cooling capabilities, etc. 

These problems often require trying out multiple solutions to eliminate probabilities. For instance, there can be multiple reasons behind an RTX 3000 series fan spinning issues

According to AMD, the 5900X boost clock is 4.8 GHz. It’s also called the 5900X boost frequency. And the 5900x base clock is 3.7 GHz. 

It means that there’s a lot of overclocking potential that you can achieve. 

But that’s where the problem occurs. Many people have complained that their 5900X is only boosting to 4.2 GHz. People have also reported that 5900X precision boost overdrive isn’t working. 

And if you’re here that means you’re having the same problem. Luckily for you, we got multiple solutions. 

Simply go through them one by one and try them out. This will help you narrow the source of the problem. 

Solution 1: Reset CPU Core Ratio

If you own an ASUS motherboard or a Gigabyte motherboard, you may have this problem. You also may run into the problem if you have used third-party software.

Even ASUS AI Suite or AMD’s Ryzen Master can create this core ratio problem.

When the problem occurs, it sets your CPU core ratio to a certain value. When the CPU core ratio is set to a certain value, it’ll be a limiter. In other words, the clock speed won’t go beyond that value. 

For example, you’ve set the CPU core ratio to 37.50. It means you’ve locked the boost clock to 3.75 GHz. 

Technically, having a certain core ratio means you’re locking the 5900X boost speed.

The boost speed of 5900x can go up to 4.8 GHz. If your CPU is not reaching that overclocked speed then there’s probably something wrong with the CPU core ratio.

That’s why we’re going to start from there. 

Follow the steps below and you’ll be fixing it in no time. 

Step 1: Access the BIOS Settings

The first thing you need to do is to get into the BIOS settings. There are a couple of ways to do it.

You can press the DEL or F12 button to enter the BIOS settings. In some motherboards, there can also be F10 or F11 buttons. 

Find out the BIOS button and press it to enter the BIOS settings. 

Step 2: Find the Overclocking settings

You’ll now have to find the overclocking settings. It can also be mentioned as tweaker settings. It depends on your motherboard manufacturer.  

After entering the BIOS, find the settings related to overlocking or tweaking. On ASUS motherboards, the menu is called AI tweaker or extreme tweaker. 

On MSI motherboards, you can find this setting in the OC section. 

Upon entering the overclocking setting, you’ll see the CPU core ratio right away.

Step 3: Check the CPU Core Ratio

It’s the moment of truth. Check the CPU core ratio setting for a certain value. You’ll find a specific number like 38, 40, or 44.5. 

This number determines your clock speed and locks it. For example, 40 means the clock is locked at 4.00 GHz. 

If you find a specific number stated in the core ratio, you’ll have to remove it.

Step 4: Reset the CPU Core Ratio

All that’s left is to reset the CPU core ratio back to normal. Luckily, you can do it right away. 

Use your keyboard to access the core ratio settings. Afterward, write the word “auto” in the box. If you can’t write auto, you can also put a 0 in the box. 

This concludes the reset process but there’s still one task left to do!

Step 5: Reset the RAM to D.O.C.P 

It’s time to reset the RAM or D.O.C.P. If it’s already done yet, that’s great. If you haven’t, you’ll have to reset it right now. 

Changing the CPU core ratio might reset the RAM that’s why you’ll have to double-check it. It can be tricky sometimes; getting 3200 MHz ram speed on Ryzen

Go to the RAM settings and set it to D.O.C.P. Make sure to put the right BUS speed while you’re doing so. 

And you’re all done! Make sure to save the settings and boot the computer. Afterward, go to the task manager setting to check the clock speed.

You can now tweak 5900X overclock settings using PBO. This will help you get the desired 5900X overclock results

If you do everything right, you can get up to 5 GHz of speed from your chipset. It might seem unbelievable at first but it’s completely true-

Speaking of overclocking, motherboards are equally important to achieve better results. Many times, it’s the motherboard which bottlenecks your CPU! So, getting a hig-end or better motherboard can be a good decision.

If you want to check out some next gen motherboards to upgrades, we’ve the perfect suggestions-

These motherboards will definitely allow you to get that sweet overclocked speed you’re looking for!

Solution 2: Update the BIOS Firmware

If resetting your CPU core ratio didn’t work, then you’ll have to go a little further. Updating the BIOS is your next big shot.
