  • Motherboard Compatibility: First of all, you need to go over your motherboard’s specifications and figure out which RAM is compatible with it. If you’re building a new rig, then we recommend you purchase your motherboard first and then move toward the RAM. By going over the motherboard compatibility, you will know whether you need to go for DDR4 or DDR5 RAM, and this alone can make all the difference in the world. Furthermore, you will know the maximum capacity and frequency that your motherboard supports.
  • Budget: You must also outline exactly how much you can spend on RAM. DDR5 RAM is generally priced a bit higher than DDR4, but its high performance makes up for the higher price tag[1]. As expected, the more performance, looks, and bells and whistles you go after, the more you will have to spend. Therefore, it is best to keep your budget in mind throughout the buying process to ensure you don’t overspend on RAM.
  • Number Of Modules: When purchasing RAM, you’ll encounter kits available in different configurations, such as kits of 2 or 4. For instance, a 16GB DDR5 RAM kit of 2 includes two 8GB RAM sticks, totaling 16 GB. Check your motherboard’s DIMM slots to determine how many RAM sticks it supports. Opting for a kit of 2 RAM sticks enables dual-channel performance, maximizing efficiency[2]. If your motherboard has 4 DIMM slots, consult the manual to ensure proper dual-channel support.
  • AMD EXPO vs. Intel XMP: AMD EXPO[3] and Intel XMP[4] both aim to optimize RAM performance by replacing default profiles with higher clock speeds and lower latency. These profiles simplify RAM overclocking, eliminating the need for manual adjustments to voltage, speed, and latency. While AMD EXPO is royalty-free, Intel XMP requires certification from manufacturers. However, compatibility isn’t restricted to specific platforms, meaning AMD EXPO RAM can be used on Intel systems and vice versa[5]. Simply enable the corresponding profile in BIOS settings to experience improved performance regardless of platform choice.

Specifications To Consider

When you’re in the market to buy RAM, then you must have noticed that every RAM has a bunch of specifications attached to it. Let’s go over what they are and how much they matter.

  • Capacity: Determine your RAM needs based on your usage requirements. For casual web browsing, 8GB is usually sufficient, while gaming may require 16GB[6]. For optimal gaming performance or video editing, consider investing in 32GB[7]. Remember, the amount of RAM you require directly correlates with your intended usage, with higher capacities generally commanding higher costs.
  • Frequency: RAM frequency, denoted by the number in the RAM’s name (e.g., DDR5-6000), represents how many read/write cycles the RAM can perform per second[8]. For example, a RAM with a frequency of 6000MHz can perform around 6 billion cycles per second. Higher frequencies indicate faster RAM. However, frequency alone doesn’t determine speed; timing latency is also crucial.
  • CAS Latency: The Column Access Strobe (CAS) latency measures the delay between the CPU sending a command to the RAM and the RAM executing that command on the data[9]. In RAM specifications, CAS latency is part of the timing latency, represented by a series of numbers separated by dashes. For instance, in the CORSAIR Vengeance RGB DDR5-6000 RAM, the timing latency is indicated as 36-36-36-76, with each number denoting a different latency parameter. These parameters typically include Column Access Strobe Latency, Row Address to Column Address Delay, Row Precharge Time, and Row Active Time. When purchasing RAM, it’s crucial to consider both frequency and latency to ensure optimal performance. RAM with high frequency but high latency may not perform efficiently[10], so finding a balance between low latency and high frequency is essential.
  • Voltage: With DDR5 RAM becoming more prevalent, concerns about input voltage are less pressing due to its improved power efficiency compared to DDR4[11]. However, for those considering overclocking their memory, examining input voltage is crucial. Overclocking RAM typically involves raising its input voltage to enhance performance[12], so ensuring the RAM’s voltage offers sufficient headroom for safe adjustments is essential.
  • Heatspreader: The heatspreader, as its name suggests, plays a vital role in dissipating heat evenly across the memory chips, facilitating efficient ventilation within your system[13]. By reducing the temperature of the memory chips, the heatspreader prevents thermal throttling, ensuring optimal performance. Additionally, manufacturers often utilize the heatspreader to enhance the aesthetic appeal of RAM sticks, offering distinct and unique designs.
  • Height: While often overlooked, considering the height of RAM is important, particularly for compact builds with limited space, such as Mini-ITX rigs. Insufficient clearance may lead to compatibility issues with large CPU coolers, necessitating a return or exchange. Low-profile RAM, with a height typically around 32 to 33mm, is recommended for small form factor PCs, offering compatibility without sacrificing performance.
  • RGB: While aesthetics may not be paramount, they hold significance for many gamers aiming to create visually striking gaming setups. RGB-enabled RAM, while often pricier, adds a vibrant visual element to builds. Additionally, RAM with customizable RGB lighting allows users to align their PC’s aesthetic with specific themes or color schemes, enhancing overall visual appeal.
  • OC Potential: Overclocking RAM can significantly boost performance, provided the RAM has the necessary potential for overclocking. This includes reliable input voltage support and a robust heatspreader capable of managing increased heat generation. Moreover, motherboard compatibility is crucial, as not all motherboards support high-frequency RAM overclocking. When purchasing RAM, particularly for overclocking purposes, ensure it offers sufficient headroom for voltage adjustments and matches your motherboard’s supported frequencies.
