Crucial when constructing or upgrading a computer are the RAM and configuration choices. Regrettably, numerous users who lack familiarity with intricate terminology frequently obtain systems in which RAM becomes a performance bottleneck. As a result, the following is an exhaustive buying guide that addresses all the concerns you should have prior to purchasing RAM.
Describe RAM.
To provide context, Random Access Memory (RAM) serves as an operating system-managed transient storage centre that facilitates rapid data transfer rates. As a result, it is a highly suitable option for existing programmes, processes, and applications.
Consider your computer to be nothing more than a workstation with cabinets. Although the processor stores data permanently in the containers, it retains information that is frequently accessed on the desk to facilitate fast retrieval. The RAM is symbolised by the desk in this analogy, which permits the processor to temporarily but rapidly store information.
Variety of RAM

DIMM (Dual In-Line Memory Module) is the configuration of RAM found in desktops and servers, while SO-DIMM (Small Outline DIMM) is the configuration of RAM found in laptops and compact computers. Although these form factors have a similar name, they cannot be used interchangeably. As a result, it is not possible to insert a DIMM card into a SO-DIMM receptacle or vice versa.
Variable form variables
As the pace of RAM has a direct effect on the efficacy of a system, we shall begin by examining various form factors. What is the meaning of the terms DDR3 and DDR4, which you may have encountered? RAM is powered by Double Data Rate (DDR) technology, which signifies the execution of two data transfers per clock cycle. As technology advanced, successive generations of RAM were introduced, bearing designations such as DDR, DDR2, DDR3, and so forth. At the present time, both DDR4 and DDR5 are operational.
DDR4 as opposed to DDR5? What is the distinction?
Choosing between DDR4 and DDR5 is arguably the most critical choice that must be made. DDR5, as its name implies, provides enhanced performance as a result of its architectural redesign. Furthermore, DDR5 DIMMs have two distinct 32-bit channels, effectively doubling the burst length from 8 to 16 bytes, in contrast to DDR4’s single 64-bit channel. This fundamental modification substantially enhances the efficacy of the memory.
Moreover, in comparison to DDR4’s 1.2V, DDR5 operates at a lower voltage of 1.1V, rendering it more power-efficient. This distinction can accumulate during prolonged periods of PC usage. Nevertheless, it is imperative to acknowledge that precise operational voltages might differ among different brands.
Which should you purchase?
DDR5 may appear to be the preferable option due to its many benefits; however, the final decision will depend on the specific requirements of your PC. DDR4 is widely supported, extending from the most recent Intel 14th Gen processors to those introduced in 2014. This is owing to its elder age. Conversely, DDR5 is restricted to processors of the 12th and 13th generation manufactured by Intel; the sole desktop processor that necessitates DDR5 is the AMD Ryzen 7000. Therefore, in the case of an ageing processor, DDR5 RAM becomes inappropriate and quicker DDR4 RAM is the superior choice.
What is the capacity?
The subsequent critical stage in the RAM selection process involves ascertaining the capacity, a factor that is significantly impacted by one’s workflow. Variations in RAM capacities consist of:
- 8GB is adequate for assembling an entry-level computer, particularly if one does not intend to engage in AAA gaming.
- 16GB: Optimal for users whose daily workflow includes gaming and multitasking.
- 32GB or more: Optimal for high-end enthusiasts and professionals who engage in resource-intensive activities and duties.
