When it comes to Ryzen 9 5900x, picking a good RAM is vital if you want your rig running the best games as optimized as possible. With so many RAM options to choose from, picking the best one to complete your rig might be tougher than you think.

With a good RAM, your computer will be able to speed up data retrieval for processing. This is why it’s very important that you pick a good RAM to complete your rig. On this list, we’ve compiled the best of the best when it comes to RAMs for Ryzen 9 5900x. There’s an option for all budgets too so without further ado, here are the top RAMs you might want to consider.

01 Corsair Vengeance LPX

Corsair is one of the leading brands when it comes to PC parts so it shouldn’t be surprising that they have a good RAM to offer as well. When it comes to RAM, the best Corsair has to offer is the Vengeance LPX which epitomizes power and performance.

In our opinion, the Vengeance LPX is the best and most suitable RAM for Ryzen 9 5900x. It has a maximum frequency of 3200 MHz and it can support overclocking as well. Additionally, this RAM is also notable for its lower latencies as compared to others on the market. It supports all high-speed gaming machines which is exactly what the Ryzen 9 5900x is built for. It is a RAM made out of pure aluminum which helps increase the heat efficiency of the entire rig. Overall, it is the perfect RAM for PCs that overheat because of its high-performance heat spreader. It is also thanks to the 8-layer design PCB that helps you utilize overclocking on your PC. If you’re picky with aesthetics, the only problem you might have about this RAM is that it doesn’t have RGB LEDs. Perhaps the best of it all is that the Corsair Vengeance LPX is a perfect device for compact cases thanks to its impressive heat regulation.

03 Thermaltake Toughram RGB

RAM needs to be tough and durable aside from being able to perform well. Our pick for the best RAM overall might just have to be the Thermaltake Toughram RGB. It’s a testament to Thermaltake’s line of work and it shouldn’t be surprising that they’ve created such a masterpiece. One of the standout features of Toughram RGB is its design. It’s a dark-brushed aluminum spreader that’s lined with an RGB bar that further makes this an excellent piece for most PC rigs. In terms of design and overall aesthetics, there’s no other RAM out there that offers the quality of looks that the Toughram RGB has. What about it’s performance? This RAM runs at an impressive 3600 MHz with XMP frequency. Surprisingly though, despite its high frequency, the latency of this RAM lags at C18. By comparison, most gaming RAMs have C16 latency for the best gaming experience possible. Despite this minor setback, however, the Toughram RGB is still one of the best performers on the market because of its loose timings. Benchmark tests reveal that the Toughram RGB is the best Ryzen 9 5900x. It is capable of performing above average when it comes to gaming benchmarks. It’s also a good RAM for professional compressions and even editing software. Another amazing feature of the Toughram RGB is it’s customization and monitoring tools.

04 Crucial Ballistix

If you’re hoping to use your Ryzen 9 5900x RAM for general use other than gaming, then you might want to consider getting the Crucial Ballistix instead. It’s the best mid-price ranged RAM for the processor. It can be aimed for editing, gaming, and other tasks. What’s better is that there are RGB and non-RGB variants of this RAM. The Ballistix offers 3200 MHz in its DDR4 RAM. There are dual 8GB modules at work and it supports XMP 2.0 as well which means overclocking is a possibility with this RAM. It’s fairly easy to switch between XMP and JEDEC profiles on your PC’s BIOS which again shows exactly how versatile this RAM is. At a height of 1.54 inches, the Ballistix RAM from Crucial is very easy and straightforward to install. Due to it’s size, it’s easy to have the Crucial be swapped out for most RAMs on the market so getting an upgrade will be easy. Crucial has given the Ballistix a heat spreader design that is less bulky than others but is still more than capable of distributing heat evenly throughout the rig. The piece is smaller thanks to its lack of fins which is also an upside as it’s easier to install other things on top of the Ballistix as well. At max capacity, the Ballistix has a latency of CAS 14 with manual overclocking.

05 Kingston HyperX Fury RGB

Kingston is one of the best producers of PC parts out there so don’t be surprised that they have a RAM included on this list. When it comes to Ryzen 9 5900x processors, Kingston’s flagship RAM is the HyperX Fury RGB. It’s fast, stylish, and it’s in the mid-range pricing. At a glance, what we can say is that the Kingston HyperX Fury RGB is a super fast RAM with very low latencies. It has RGBs that can be too bright at times though. However, thanks to the RAM’s bold design and addressable RGB on the memory modules, it’s easy to overlook this one downside of the Hyper X Fury RGB. It is one of the very few RAMs to offer a very low latency profile of only CL16. Considering that the RAM has a frequency of 3200 MHz at 1.35v, this latency is very impressive. It’s also worth noting that the RAM can support extreme overclocking with XMP 2.0. If your rig is powerful enough, you can reduce the latency to CL15 but this means lowering the frequency to at least 3000 MHz. It is a very efficient RAM module as well thanks to its capabilities. In terms of sizing, the RAM has a height of 41mm which makes it capable of supporting bigger processor coolers and even small cases. When it came to benchmarks, the HyperX Fury RGB was able to achieve a read/write speed of 44GB/s and a copy speed of at least 39GB/s at a frequency of 3200 MHz. The HyperX offers premium performance at a mid-ranged price.

The RAM is said to reach a maximum voltage of 1.35v with a frequency of 4000 MHz. Still, the latency of the RAM is still capable of C18 with 2T.  In terms of scores on various aspects, the Vengeance RGB Pro was able to achieve great scores in terms of compression, bandwidth scaling tests, and gaming tests. With extreme profiles, the latency can be dropped to C15 with a frequency of 3000 MHz or even C16 with a frequency of 3200 MHz. Like most of the Corsair PC pieces, the Vengeance RGB Pro is compatible with the Corsair iCUE software. This makes it very easy for anyone to customize the RGB LEDs on the device.

07 Patriot Viper III Black Mamba

The only DDR3 RAM on this list is the Patriot Viper III Black Mamba. Despite being a DDR3 RAM, the Patriot Viper III Black Mamba is still an impressive RAM that deserves a spot on this list of best RAM for Ryzen 9 5900x. Why should it stay on this list? For starters, the Black Mamba is one of the cheapest RAMs on the market currently. Despite it’s price, the Black Mamba doesn’t lag behind performance. In fact, it’s one of the fastest RAMs out there. It has a maximum frequency of 1833 MHz which is very high for a DDR3 RAM. To make up for its low frequencies, the Black Mamba makes it up with very low latencies which can reach up to CL10. This means a high response rate and an amazing performance. The RAM comes in various variants with differing frequencies from 1600 MHz to 2400MHz. This wide variety of options is good for buyers that want to fully customizer their rig depending on their needs and current budget. If you’re looking for the best variant of the Black Mamba for Ryzen 9 5900x computers, go for the middle 1833 MHz variant which is more than enough for gaming PCs. The Black Mamba has been tested rigorously on AMD and Intel motherboards and the results reveal that it’s a fully compatible RAM for them. The biggest edge of the Black Mama though is its lower CAS latency which reaches CL10. By comparison, all of the other RAMs on this list can only reach a latency of C14 at best. The RAM also supports XMP 1.3 but it does not support XMP 2.0. You might experience a few setbacks with this but don’t worry, the RAM has a lifetime warranty which is a big plus.
