What is the correct CPU overclock voltage?
What is the correct CPU overclock voltage?
Hello there,
I’m wondering why my BIOS settings remain static and why they change to a lower frequency during stress testing? For instance, I’ve configured a multiplier of 50x, 1.4v, and everything appears normal until I begin the OCCT test. Then both the frequency and voltage drop significantly. Even after disabling all features (power savings, etc.), this continues to happen. Conversely, when I set a lower voltage (1.220v) and multiplier (45x), the vcore spikes to around 1.35v during stress tests, which is unrealistic for that frequency. I’m puzzled by these changes and want to understand what’s causing them.
Temperatures are within acceptable ranges. I’m not running any power virus like Linx.
Thank you for your advice.

Hey there,
This is referred to as vdroop during voltage drops. It occurs when the motherboard fails to supply the voltage required by the BIOS. This issue can be resolved by adjusting the LLC to a higher setting. For LLC, there are usually four levels, though sometimes it's 1, 2, 3, or 4. In other motherboards, it might be low, medium, high, etc.
But why is static voltage being pumped at 1.4v? This isn't ideal for the CPU in the long run.
For the voltage increase during undervolting, there must be a specific setting influencing this change. It shouldn't exceed if you've already fixed it.
True, but I'm not entirely confident. If I can cool it down, it doesn't matter whether it's 1.45v or 1.4v. I understand how the LLC works, so don't worry. I'm trying to find a balance and wait for my AIO cooler before experimenting more. It seems like 1.45v would be safe, right?
I wouldn't exceed 1.38, would you? It's better to preserve your equipment rather than risk damaging it. In practical use, the difference between 4.8 and 5.0 is usually unnoticeable. Only the top 17% consistently reach 5.0 across all cores.

I don’t want to burn up anything, but I’m aiming for the best performance possible. This processor can reach 5.0GHz across all cores, just by increasing the voltage. 1.45v works well, though it struggles under AVX stress tests.
2) In practice, the difference is minimal, but I always wanted to push it to 5GHz and it performs fine.
3) I’m not sure where this comes from, but it’s a silicon lottery. My chip isn’t, but that doesn’t stop me from trying to get 5GHz on all cores with just a bit more voltage.
5.0 is not a magic number, I can run my 10600K faster than 4.8 but no reason to.
The silicone lottery numbers are from the processors they have tested but they sell the top performers for a extra cost.
Your processor and motherboard do as you wish. 1.45🧨
EDIT from my above post.
From this only the top 17% can hit 5.0 on all cores. ( @ a safe voltage)
