Is it possible to enhance the CPU’s L2 cache memory?

If you are someone who uses your computer for memory performance, you might find it helpful to understand how caches function and which sizes are important when selecting a PC. The LWN.net website published an article on CPU caches in October 2007, which may provide some insight. Unfortunately, it is not possible to manually replace the built-in CPU cache as it is part of the system on a chip (SoC).


Solution 1:

The CPU incorporates the L2 cache within itself, and upgrading to a CPU with a higher L2 cache is the only way to obtain more of it.

As a budget processor, the Celeron naturally has a smaller cache compared to your C2D.

Is having additional cache likely to result in faster performance? Generally speaking, it’s true.

You can upgrade your desktop’s CPU with a faster clock speed and increased cache, depending on its socket type.

The second part of the memory topic focuses on CPU caches and was discussed in an article published on the LWN.net website in October of 2007.

Ulrich Drepper’s “what every programmer should know about memory” document has a second installment, which is excellent content. For those who haven’t read the first part, it’s recommended to start there. We are grateful to Ulrich for permitting us to publish this valuable information.

The article, which is quite lengthy, may provide insight into the reason behind relocating the caches to the processor module. This is a departure from the earlier days that

referred to in the previous comment, which are best left in the past.

ExtremeTech has published a note regarding the L3 cache of Nehalem.


An additional update to my previous post includes a reference to an old overclocking article. I did not include it earlier because it is not relevant to L2 Cache scaling. However, it is still worth reading in the context of my response to another answer provided by

From the article titled “Three Gems for an Overclocker”, regarding the processor model Intel Celeron 2GHz.

The Intel Celeron processors shared the same cores as faster processor families, but with smaller L2 cache, lower bus frequency and clock frequencies. Overclocking can significantly boost the speed of low-cost processors, but the halved cache cannot be recovered. Recently, Celeron processors adopted a 0.13micron Northwood core, which made them easy to overclock and achieve core frequencies comparable to the fastest Pentium 4 models, reaching up to 3GHz. However, the 128KB L2 cache limitation holds back Celeron from breaking all overclocking records.

No, no and yes, in that order
