What is the difference between buffered and unbuffered RAM?
RAM is an abbreviation of Random Access Memory. The memory requires a constant flow of power to retain data since it is non-volatile. The performance of a system is determined by RAM.
The main difference between buffered and unbuffered RAM is that buffered RAM contains a register between the DRAM and memory controller whereas unbuffered RAM does not contain a register between DRAM and memory controller.

What Is Buffered RAM?
It is a memory module that contains a register between the DRAM and the memory controller. It is a single system that does not place more electrical load on the memory controller.
Buffered RAM is highly applicable to high-end systems such as servers and mission-critical systems that require a stable operating environment.
It is quite easier to identify Buffered RAM due to the presence of an additional chip in the middle of the module.
What Is Unbuffered RAM?
It is a memory module that does not contain a register between the DRAM and the memory controller. It places a high electrical load on the memory controller.
Unbuffered RAM is mostly applicable in laptops and desktops. The good news is that it tends to be less expensive but unreliable in terms of data storage.

Buffered vs Unbuffered RAM FAQs
Is Buffered or Unbuffered RAM Better?
Unbuffered RAM is the best choice for the standard system due to its affordability and higher performance. But buffered RAM is a great bet for critical systems that require a more stable operating environment.
Can You Use Buffered and Unbuffered Memory?
No. The design of computer memory tends to dictate whether to use buffered or unbuffered memory.
Is Unbuffered RAM Better for Gaming?
No. The RAM is typically meant for workstations. The best memory module for gaming is buffered RAM due to its reliability and stability.
How Do I know If My RAM is Unbuffered?
It is advisable to look at the leads next to the first notch. Unbuffered RAM does not have evenly spaced leads.
