Best RAM for Ryzen 9 5900X

Memory plays a vital role in PC performance, mainly when performing heavy tasks or playing advanced games. Picking the best RAM for Ryzen 9 5900X ( Amazon )needs some technical expertise; let’s take a glance at RAMs briefly to get a good idea of how they function and how vital they are. So, what exactly is RAM? Random Access Memory or RAM is a memory used in computers to speed up data retrieval for processing. Hard drives are prolonged compared to the processing power of a CPU. They cannot send data to the CPU fast enough, so RAM holds the most commonly accessed files and information in its modules for faster access and processing. Better access times substantially improve the data processing speed of a system. In short, RAM plays a tremendous role in your system performance and shouldn’t be ignored.

RAM stores all of the critical operating system data and applications that you are using, such as browsers, office software, games, and so on. With newer features being introduced to programs regularly, the RAM demand is constantly growing. What seemed enough last year is barely adequate this year. Major factors that impact RAM selection are capacity, frequency, and CAS latency. The purpose of the PC highly affects these parameters. General-purpose and office work systems require less capacity of RAM, whereas gaming systems require more. Similarly, the creative application requires a high capacity of RAM, whereas Gaming PC requires high-speed RAMs and high capacity.

Have a look at our shopping tips for the Ryzen 9 5900X best RAM. They will let you reach a better decision about RAM selection.

Quick Shopping Tips:

MEMORY SPEED: Memory comes at various speeds that change with the generation, commonly known as DDR/SDR (Dual/Single Data Rate) versions. Higher speed RAM speeds may increase system performance if compatible with a system, whereas a higher DDR version not supported by a system does not add to the performance of a system. Manufacturers often launch overclocked variants of RAM modules to boost speed further, but the rule is that, don’t go beyond system-supported frequencies.

CAPACITY: RAM capacity depends on the number and size of the applications you will use on your systems. Regular applications like browsers and MS Office consume less RAM, whereas creative software and games require a massive amount of RAM. A 1080p up to 2K gaming system requires at least 16 GB of RAM, but if you want to run the most resource-intensive games on 4K with the most potent 5900X, go with 32 GB or more for best results.

LATENCY: The time required to retrieve/write any data/information from a memory module after a READ/WRITE command is given, known as latency. The lower the CAS (Column Address Strobe) numbers, the quicker a RAM will fetch data and perform faster. It is desirable to use lower latency RAM for gaming machines, whereas average latencies will do typical systems quickly.

VOLTAGE: Users usually shouldn’t be concerned about RAM voltages and don’t need to tinker with them. Voltage manipulation is the domain of overclockers that tweaks the RAM voltages to change frequencies. Generally, the higher the voltage, the higher the frequency and thus the speed. However, raising RAM voltages also generates more heat, which needs to be taken care of. Gamers often overclock their RAMs to achieve better results.

NO. OF SLOTS: The capacity of each slot is limited by the motherboard type and generation. You should install RAM in pairs or quads. AMD and Intel support dual-channel memory mode that significantly improves memory performance when used in pairs and quads. Furthermore, if you don’t have an extra RAM slot, it’s wise to buy a RAM slightly higher than your required capacity for future-proofing your rig for the next few years.
