Best RAM for Ryzen 9 3900X

Gamers always wish to play games in high-end settings while content creators want to create top-notch content without feeling any lag in their system. It’s possible but you would need to have some good-quality components in your system–RAM memory is one of them. Volatile memory takes information from the storage memory and stores that, making it more accessible for the processor. If you somehow manage to choose the best RAM for Ryzen 9 3900X, you can enjoy a peak-level performance from the chip and your system. 

AMD is a well-known processor manufacturer and has a long list of all-time favorite CPUs and other products. The brand’s Ryzen 9 3900X is a great and capable processor with 12 cores, 24 threads, and a base clock speed of 3.8GHz that can bump up to 4.6GHz boost clock speed. Interestingly, this processor has the same performance as the older entry-level Threadripper but with an excellent non-Threadripper chipset. So, it can be installed on a wide range of consumer-grade motherboards. 

In short, this processor is perfect to use for content creation and gaming but you must pair it with other elements of the same caliber. In this way, you can effectively utilize the true potential of the chip. Remember that the current tech market situation is quite complicated since there are hundreds of memory kits from tens of brands. So, you have to get some help from experts and be extra careful while checking different products. If you want to save time, you can check eight products in this along with their in-detailed reviews.

Quick Shopping Tips:

Brand: There are several manufacturers that are making RAM kits for a wider range of users and computers. Maybe because of this reason, many of our customers often get confused while selecting the brand name. In reality, the products and performance of the kit are way more crucial than the name since it doesn’t matter that much. I suggest going for a budget-friendly volatile memory with great performance rather than choosing a certain brand’s name

Memory size: The next foremost important factor on the list is the total memory size of the memory kit. For your information, it’s a system-based factor that totally depends upon the load, requirements, and usage. If you’re building a system to play games, you can’t go for anything below 8GB memory size. In contrast, the upper limits, again, depending upon how much load you will put on the rig and what types of games you will play on the computing system. 

Clock speeds and overclocking: Like the other elements, RAM also comes with certain clock speeds: base clock and boost clock. The margin between both of the ratings is the overclocking headroom. The clock speed directly impacts the overall performance of the PC. You must choose a memory kit with higher clock speeds and a more significant overclocking gap. At the same time, make sure that the motherboard also supports the ideal clock speeds. 

Timings: Another factor that plays a key role in the overall efficiency and memory performance is the RAM’s timings—it’s also known as CS latency. It’s inversely proportional to the CPU and computer’s speeds. On average, you can go for a kit with a CAS latency of 16 but again, less is better. In short, if you have two kits in front of you, the one with the lower timings will perform better and will provide way better performance than the one with higher latencies.

Compatibility: In this section, we’re talking about compatibility in terms of the memory modules’ size. In the current era, most of the kits are coming with RGB lighting so the profile height. The thing you have to check is whether there is enough space to accommodate and fit these modules on the motherboard or not. If not, go for one with low-profile memory modules. In such a case, you may have to compromise the RGB lighting which won’t be an issue since it also saves bucks.
