Best RAM for the AMD Ryzen 9 5900X

It did not take long for AMD’s initial batch of Zen 3 Ryzen 5000 Series processors to completely sell out. This can, in part, be attributed to a lack of stock, but it cannot be denied that the demand for these CPUs is off the charts – and for good reason.

The flagship Ryzen 9 5900X, for example, outclasses AMD’s chief competitor, Intel, in multiple facets associated with CPU performance; while still costing less than Intel’s flagship CPU. It has two additional cores, four additional threads, more than three times the amount of L3 Cache, and a half-sized processing node; allowing it to have far better multicore performance, and, with the new Zen 3 CCX (Core Complex) architecture, it also performs similarly to the Intel i9-10900K in single-core dependent workloads, like gaming applications, as well. In fact, TechSpot’s benchmarks show us that the Ryzen 9 5900X achieves this level of performance, despite consuming 23% less power than its Intel counterpart. Note, that these benchmarks are carried out using an Nvidia GPU, which means that the Smart Access Memory feature found in Ryzen 5000 Series CPUs and Radeon RX 6000 Series GPUs is not being utilized.

If you are looking to build a new PC around the Ryzen 9 5900X, you will want its accompanying hardware components to allow it to reach its maximum potential – and RAM is one of the most important pieces to needed in order to accomplish this task. To help you find the best memory the market has to offer, we have compiled a list of the most optimal RAM kits to pair with the Ryzen 9 5900X – based on speed, price, and, of course, availability.

Note: All prices are for two ranks of 8 GB of RAM: 16 GB in total.

One of the more popular RAM speeds for gaming applications is that which has a 3,600 MHz frequency, and a Column Address Strobe (CAS) latency of 16 cycles. This speed has proven to provide framerates above what the conventional 3,200 MHz CL14 is capable of when not overclocking – as proven by benchmarks from Wolfgang and GamerNexus for a multitude of gaming titles. So, if you do not want to worry about overclocking your RAM on a regular basis, this speed is perfect for your build. One of the best models featuring this speed: The G.Skill’s Trident Z Neo.

This RAM has it all. A Samsung B-Die (which is the best die to pair with AMD’s Ryzen CPUs), an excellent heat spreader with a brushed aluminum and powder-coated silver exterior, a 10-layer PCB, hand-screened Integrated Circuits (IC), and a stylish slanted and asymmetrical RGB displays that features eight-zone RGB lighting.

Purchasing G.Skill’s Trident Z Neo Series RAM can currently cost you as low as $125.08; for prices do fluctuate depending on season and availability.

Best Non-RGB Gaming RAM for Ryzen 9 5900X – TEAMGROUP T-Force Dark Pro

TEAMGROUP T-Force Dark Pro
Module Type288 Pin Unbuffered DIMM Non ECC
Capacity16GB Kit (8GBx2)
Data Transfer Bandwidth25,600 MB/s (PC4 25600)
Dimensions45(H) x 134(L) x 8(W)mm
Tested Voltage1.35V

Though a 3,600 MHz CL16 speed does offer slightly better frame rates for gaming, it is inferior to a 3,200 MHz CL14 RAM in terms of absolute latency (8.88 nanoseconds vs 8.75 nanoseconds respectively). This means that the 3,200 MHz RAM can be overclocked to even faster speeds, such as 3,600 MHz CL15, and therefore increase overall performance.

The TeamGroup T-Force Dark Pro RAM kit does make this task very simple, as it has XMP 2.0 compatibility – so you can save overclocking profiles and execute the task in just one step – and, with its five-layer heatsink and aluminum heat spreader, you won’t have to worry about overheating issues affecting the hardware or its performance. 

The T-Force Dark Pro also features an JEDEC RC 2.0 custom circuit that increases transmission signal by a significant amount (up to 35%) by using an architecture that separates the power layer and signal layer circuits. Together with the Ryzen optimized Samsung B-Die, this RAM features data transfer speeds of 24.6 GB/s.

Bereft of any lighting displays or exterior fluff, this RAM makes the most of its 3,200 MHz frequency and 14-14-14-31 CAS timing; and it does so at an incredibly low price of only $129.99.

As DDR4 RAM technology has progressed, so have manufacturing techniques and efficiency. This has resulted in high-performance RAM, at a much lesser price than what was initially available. It is for this reason that we now have the luxury to find 3,600 MHz CL 14 RAM at a price that used to simply be unapproachable.

The Corsair Vengeance LPX features this exact speed, that allows for high-level overclocking for both gaming and workstation purposes. The Vengeance LPX has a pure aluminum heat spreader and a custom-built PCB, which, together, allow it to achieve and maintain its overclocking capabilities.

It also has individually screened ICs, for increased durability, and XMP 2.0 support, so you can save overclocking profiles for quick and easy access. Finally, it must be mentioned that this RAM kit features a low-profile design, and, thus, it can fit into a PC of any form-factor.

The Corsair Vengeance LPX may not have a RGB-illuminated display, or a flashy exterior design, but it performs at incredible speeds, and will only cost you $179.99.
