But what is ring ratio?
And why does it matter?
Lets dive into this article to know the answers, shall we?
What Does CPU Ring Ratio Mean?
In short, ring ratio is the technical name for CPU cache speed adjustment.
Cache/Ring Bus speed means the speed that the ring bus/LLC (L3 Cache) runs at.
CPU overclocking is pretty straightforward on its own but there are some elements that might cause performance stability issues.
For ensuring a stable boost frequency, users need to adjust the ring ratio value from the BIOS.
Otherwise, the performance might throttle and the program might even crash.
So why does it happen?
Well, processors usually operate at a much higher speed than the system memory/RAM.
After overclocking the CPU, the processor speed becomes faster than the cache speed.
As a result, if you dont increase the cache speed as well, the data-feeding process becomes slower.
In most cases, it doesnt affect much.
But in certain CPU-intensive tasks, it matters.
This is why adjusting the ring ratio value when overclocking the processor is quite useful.
Although the performance increase is almost negligible.
For my i7 12700k, increasing the ring ratio came with a diminishing return.
I only noticed a slight performance increase in synthetic benchmarks.
Furthermore, there have been reports ofunstable overclocking due to increasing the ring ratio.
So you might as well leave this option untouched if youre unsure about it.
you’ve got the option to alsocheck if the overclocking profile is stable or not.
CPU ratio is for core clock speed, and ring ratio is for cache speed.
CPU core ratio is actually a multiplier that determines the processor clock speed.
CPU clock speed is calculated by multiplying the core ratio with the base clock speed(BCLK).
Suppose, the core ratio is 45 and the BCLK is 100MHz.
So the CPU clock speed will be 4,500MHz or 4.5GHz.
Meanwhile, the ring ratio is the multiplier for cache speed.
This dictates the cache frequency, along with the memory controller speed.

Wrapping Up
In conclusion, the ring ratio is only important when you consider overclocking your CPU.
But outside of OC, its nothing to be worried about.
