Memory Type: DDR5 | Capacity: 32 GB (2×16 GB) | Frequency: 7200 MHz | Latency: CL34 | RGB Lighting: Yes | Voltage: 1.45V

Pros

  1. Extremely high 7200 MHz frequency.
  2. Good CL34 timing latency.
  3. The translucent RGB light bar makes it look beautiful.

Cons

  1. Expensive.
  2. 1.45V input voltage is a lot.

Next up on the list is the best performance RAM for Ryzen 9 7900X, and the award for that goes to the Corsair Vengeance RGB; its 7200 MHz variant to be precise. If you plan on running some high-end memory-intensive tasks on your R9 7900X rig, and you want the RAM that offers the best possible performance, then there is no RAM out there as good as the Corsair Vengeance RGB.

As we mentioned, the Corsair Vengeance RGB can achieve 7200 MHz frequency, and we don’t mean that you will have to overclock the RAM yourself to get to this figure. All you have to do is enable the AMD EXPO profile that the RAM comes with from the BIOS, and that’s it; you will get such a high transfer rate automatically. Having 32 GB of DDR5 RAM that is running at 7200 MHz is simply insane, and no matter how memory intensive your workload is going to be, the Corsair Vengeance RGB can surely handle it.

Not only that, but the RAM comes with a surprisingly low timing latency of just 34-44-44-96 as well. So, having a CAS latency of 34 clocks in a RAM that is running at 7200 MHz is phenomenal, and its performance will never let you down.

With high performance comes high power consumption, but as long as the power consumption is justified, the RAM is a success. To operate at 7200 MHz, the Corsair Vengeance RGB will need 1.45V, which might seem a lot at first glance, but if you think about it, it actually is quite a good deal. That’s because while power consumption has increased by about 31%, the transfer rate has increased by a whopping 50%. So, when you factor in its high performance, its high input voltage doesn’t sound bad at all.

High input voltage means the RAM will generate more heat, and to counter that, it must come with a reliable cooling design to ensure that the RAM does not suffer from thermal issues. Because, from a DDR5 RAM that is aimed towards extreme performance, the last thing you want for it is thermal throttling. So, to ensure that the RAM operates reliability under extreme loads, Corsair has incorporated an aluminum heat spreader which does a remarkable job at quicking getting rid of all the heat.

Going over the aesthetics, the Vengeance RGB looks exactly how you would expect a Corsair RAM to look, aggressive and gorgeous. First off, you can get the RAM in two colors, black and white, and both colors feature a dual-tone look with a huge Vengeance logo in the middle. Coupled with its massive translucent RGB light bar that goes from one end to another, the Corsair Vengeance RGB nails it in the aesthetics department, and you will have a great time showing it off to your friends.

What We Liked

Without any doubt, the best thing about the Corsair Vengeance RGB is its performance; the RAM has an extraordinarily high transfer rate. Plus, the fact that you can achieve such performance with just a click of a mouse is an engineering marvel.

What We Disliked

Overall, there is nothing to dislike about this RAM. One thing, however, is that it costs a lot more than other DDR5 RAM. But, it makes sense because it is also faster than other DDR5 RAM.

Overall

All in all, if you plan to run some heavy-duty tasks on your Ryzen 9 7900X rig, then the Corsair Vengeance RGB (7200 MHz) is the way to go. The RAM is so powerful that you will never face any memory hiccups whatsoever, no matter what you throw at it. Additionally, it also looks quite beautiful with its huge RGB light bar, which is always a plus point. So, the Corsair Vengeance RGB is hands down the Best Performance RAM for Ryzen 9 7900X.

  2. Low input voltage of 1.25V.
  3. Has overclocking potential.

Cons

  1. A bit expensive.

For those of you who are going for a white PC build, you need good-looking white components to go along with the rest of your rig, and that includes having a white PC case, a white CPU cooler, and the best white RAM. Well, for the RAM, we recommend that you go with the Corsair Dominator Platinum RGB because it not only looks out of this world but also packs a powerful punch to be called the best RAM for Ryzen 9 7900X.

Going through the specifications, the Corsair Dominator Platinum RGB is configured to run at 5600 MHz with the extreme profile enabled. For a CPU like the Ryzen 9 7900X, having the RAM run at 5600 MHz is enough performance to run any AAA title with solid FPS. Plus, since the kit we selected is 2×16 GB totaling 32 GB, you are highly unlikely to run out of memory either.

Even though its timing latency of 36-36-36-76 with the CAS latency of 36 clocks is not the best out there, it is definitely not the worst. In fact, seeing that the RAM is running at 5600 MHz and not anything below it, it is unlikely that you will find any performance difference between 36 clocks and 34 clocks.

As we have mentioned, the frequency of the Corsair Dominator Platinum RGB increases from 4800 MHz to 5600 MHz as you enable the EXPO profile. But what also increases is its input voltage, from 1.1V to 1.25V. It should be noted that having an input voltage of 1.25V is quite a good deal, and it not only ensures stable operations under extreme loads but also gives the RAM more overclocking potential. So, with this RAM, you also have the option to manually tweak the input voltage, frequency, and timing latency to get even good figures.

Featuring an aluminum heat spreader, the Dominator Platinum RGB uses the patented Corsair DHX Cooling mechanism, where not only the ICs but also the ground plane of the PCB are cooled down with the heat spreader to ensure optimal temperatures at all times.

Focusing on the looks, that’s the feature that has enabled this RAM to gather all the buzz around it. It has a distinct design philosophy combining minimalism while also paying tribute to the company’s gamer-ish vibe. Having an all-white body with subtle Corsair branding at the center combined with the 12 Capellix RGB LEDs gives the RAM a gorgeous look. Similarly, like other Corsair RGB components, you can use the iCUE Corsair software to customize the RGB however you want.

What We Liked

The Corsair Dominator Platinum RGB is truly one of the best-looking RAM to ever hit the market, and what’s best about it is that it doesn’t focus on the looks alone; it also fulfills the essentials of being a successful DDR5 RAM, that is, high-performance.

What We Disliked

The only negative surrounding this RAM is that it is priced in the upper range of the spectrum, especially considering the performance it offers. Otherwise, it is a phenomenal DDR5 RAM.

Overall

With that said, if you are building a white PC gaming rig, then the Corsair Dominator Platinum RGB is a no-brainer. The RAM nails it in the looks department and also offers significant performance. Yes, it might cost you a bit more than other DDR5 RAM, but it will also make your rig look more beautiful than theirs. Overall, it is without any doubt the Best White RAM for Ryzen 9 7900X.

G.Skill Flare X5 Series

Best Value RAM For Ryzen 9 7900X

Best Value RAM For Ryzen 9 7900X - G.Skill Flare X5 Series DDR5
G.Skill Flare X5 Series DDR5

Memory Type: DDR5 | Capacity: 32 GB (2×16 GB) | Frequency: 6000 MHz | Latency: CL36 | RGB Lighting: Yes | Voltage: 1.35V

Pros

  1. Offers the best value for money.
  2. Its 6000 MHz frequency is the sweet spot for Ryzen 9 7900X.
  3. Low-profile height of just 33mm.

Cons

  1. No RGB.

Not everyone is after the gorgeous looks that most DDR5 RAM offers. Some people just want RAM that offers the right amount of performance without costing them a bank, and for those people, we recommend the G.Skill Flare X5 DDR5 Series. Being a G.Skill RAM, you can expect it to have solid reliability and stability. Plus, since it focuses on just the essentials, it is the best bang for the buck when compared to the other DDR5 RAM.

For starters, the Flare X5 Series is capable of running at 6000 MHz with the AMD EXPO profile. As we have discussed earlier, 6000 MHz is the best frequency for a Ryzen 9 7900X, and seeing that the Flare X5 Series can achieve it without needing any manual overclocking, its price-to-performance ratio is one of the best out there.

Well, transfer rate alone cannot dictate a RAM’s performance; its timing latency matters just as much, and the Flare X5 Series has a timing latency of 36-36-36-96. Having a CAS latency of 36 clocks is a good number. It is not the lowest timing latency that we have seen, but it is also not the highest. Overall, it will not cause any performance issues whatsoever.

Going over the power consumption, the RAM will be consuming 1.35V once you crank up the frequency to 6000 MHz. Seeing how the power consumption climbs by about 22.7% and the performance increases by a solid 25%, we think it is a fairly good deal.

Look-wise, it is apparent at first glimpse that the RAM does not offer any RGB, and it makes sense because it is aimed towards the best value, and adding RGB will only increase the cost and decrease the value. However, despite not featuring RGB, the RAM still has good aesthetics due to its matte-black body, racing stripes, and grills for the memory chips to breathe.

Another good thing about the Flare X5 Series is that it has a height of just 33mm, making it one of the best low-profile RAM out there. So, if you have a low-profile chassis or a huge CPU cooler, you should seriously consider using this RAM.

What We Liked

The best thing about the Flare X5 Series has to be its value. The RAM costs less than most DDR5 RAM but offers the perfect amount of performance to stand alongside them. It is truly one of the best bang for the buck RAM out there.

What We Disliked

There isn’t anything major to dislike about this RAM. It focuses on the essentials and nails it in that department. Sure, it would have been even better to have a CAS latency of 34 clocks, but 36 clocks is not bad, either. Similarly, some people would argue that having no RGB makes it a bad RAM, but for the price, it makes sense that it does not come with RGB.

Overall

All things considered, if you don’t want to spend too much money on just the RAM yet expect high performance from it, you should go with the G.Skill Flare X5 Series. The RAM does not cost as much as other RAM, and it offers just as much, if not more, power than its competitors, making it the Best Value RAM for Ryzen 9 7900X.

TEAMGROUP Elite DDR5

Best Budget RAM For Ryzen 9 7900X

Best Budget RAM For Ryzen 9 7900X - TEAMGROUP Elite DDR5
TEAMGROUP Elite DDR5

Memory Type: DDR5 | Capacity: 32 GB (2×16 GB) | Frequency: 4800 MHz | Latency: CL40 | RGB Lighting: Yes | Voltage: 1.1V

Pros

  1. Budget-friendly.
  2. Comes with a lifetime warranty.
  3. Has a height of just 32mm.

Cons

  1. No heat spreader.
  2. CAS latency is very high at 40 clocks
  3. Performance is just average but can be overclocked.

Since the Ryzen 9 7900X can only be paired with DDR5 RAM, you have fewer options to select from as compared to the Raptor Lake line-up. This also means that if you’re on a tight budget and you only want the RAM to get you through the day, you cannot go with DDR4. For those people, we recommend the TEAMGROUP Elite DDR5 RAM. It costs way less than other DDR5 RAM, and it is not a cheap knock-off that you would expect it to break in a matter of months.

Aimed at the budget segment, the TEAMGROUP Elite DDR5 RAM does not come with any AMD EXPO profile. So, the RAM will be running at 4800 MHz unless you move towards manual overclocking, where you tweak around with the input voltage, timing latency, and transfer rate. While 4800 MHz frequency is the lowest we have seen so far, it is actually enough to get you through your day involving AAA gaming and heavy workloads.

However, what’s surprisingly higher is its timing latency, that is, 40-40-40-77, it is undoubtedly the highest timing latency we have seen, but you cannot expect anything better than from DDR5 RAM that costs around $130. 

Since the RAM is running at the standard DDR5 frequency, its input voltage is also at default, that is, 1.1V, which is really good because it not only ensures efficiency and low thermals but also gives you room to overclock the RAM if you want it to perform better than just 4800 MHz.

On the topic of overclocking, it should be kept in mind that the RAM does not come with a heat spreader. So, yes, its input voltage gives you plenty of room for overclocking, but the lack of a heat spreader means you cannot go too high, or else the RAM will begin to thermal throttle. However, you can still take it to somewhere around 5200-5600 MHz safely with the input voltage bumped up to about 1.25V, and you are unlikely to face any stability hiccups.

Since the RAM does not feature a heat spreader, it is obvious that it also features no RGB. In fact, it looks like those old-school black/blue/green PCB RAM that we used to have. However, it does not mean that the TEAMGROUP Elite DDR5 is a bad-looking RAM; many people still prefer the old-school aesthetic over the latest flashy, colorful RAM. 

Another plus point of the TEAMGROUP Elite DDR5 is that just like the G.Skill Flare X5 Series, it is also a low-profile RAM with an even better height of 32mm. So, if you are looking for a low-profile build, then you should seriously consider this RAM. Additionally, TEAMGROUP also provides a lifetime warranty with this RAM, so you have peace of mind that if something goes wrong with it, you can contact the manufacturer for support.

What We Liked

The fact that you can get a DDR5 RAM with no warranty risks at such a low price point is definitely the best thing about the TEAMGROUP Elite DDR5. The RAM is incredibly budget-friendly, and it is a blessing for those gamers who don’t want to spend a ton of money on their Ryzen 9 7900X build.

What We Disliked

The price makes it very difficult to dislike anything about this RAM. Sure, it would have been better if it came with an EXPO profile that could take its frequency to around 5200 MHz, but then again, its price would have increased because of that.

Overall

In a nutshell, the TEAMGROUP Elite DDR5 should be your no-questions-asked purchase if you are on an extremely tight budget. It is a safe RAM to buy, and you get a lifetime warranty with it. Not only that, but if you are not satisfied with the performance it offers, then you can always overclock it. Overall, it is truly the Best Budget RAM for Ryzen 9 7900X.

AMD EXPO Vs. Intel XMP: What’s The Difference?

Changing memory profiles enables users to automatically overclock their RAM without manually changing the frequency, input voltage, and timing latency. Manually overclocking RAM is quite a difficult process, and one wrong configuration can lead to a plethora of issues. That’s why pre-configured memory profiles are such a useful feature, and that’s why basically every manufacturer incorporates them in their RAM.

For the longest time, Intel boasted about its XMP feature, which stands for Extreme Memory Profile. XMP works simply: users need to head over to the BIOS settings of their motherboard and enable the XMP profile, and that’s it; their XMP-enabled RAM will be overclocked to perform better than ever.

Well, at last, AMD has finally introduced a direct competitor to Intel XMP called AMD EXPO (Extended Profiles for Overclocking). In a nutshell, AMD EXPO works exactly like Intel XMP; both profiles swap out the default memory profiles that the RAM comes with and swaps in a much better-configured profile aimed toward higher performance, allowing users to overclock their RAM with just a single click.

Without these profiles, the RAM will be running at its default clock speed, which is 4800 MHz for DDR5. So, to achieve the higher clock speeds which are written on the box, you need to activate the XMP/EXPO profile from the BIOS. 

Now you might be wondering, yes, AMD EXPO and Intel XMP work the same way; they swap the memory profiles to achieve higher performance, but is there a difference between the two?

Well, the only crucial difference between the two is that memory manufacturers need a license to call their RAM XMP-enabled. On the other hand, AMD EXPO comes without any royalty or license, which is a huge incentive for manufacturers to lean towards AMD EXPO more. 

But, as a result of Intel’s licensed certification requirements, every XMP-labelled configuration is privately tested by Intel to make sure that it passes the requirements set by Intel, which ultimately ensures high quality and safety.

Is Intel Optimized RAM Compatible With AMD Ryzen Platform?

As we discussed earlier, both Intel XMP and AMD EXPO work on the same principle, that is, to make one-click memory overclocking easier. Therefore, whether the RAM you’re going for says it is Intel Optimized or AMD Optimized, it is going to work on both platforms, and you can enable the extended memory profile from the BIOS setting to achieve the written clock speed regardless.

So, Intel Optimized RAM is compatible with the AMD Ryzen platform. That’s why some of the RAM in our selection says they feature Intel XMP 3.0 profile. Because they will work with your Ryzen build without any issues.

How We Picked The Best RAM For Ryzen 9 7900x

Whether it is RAM, CPU coolers, or motherboards, Tech4Gamers has specific criteria to test each and every component. In this section, we will briefly walk you through several factors we kept in mind when selecting the best RAM for Ryzen 9 7900X.

Even if you’re not building a Ryzen 9 7900x rig, you should still consider these points whenever you’re buying RAM for any PC.

Budget and Affordability

First and foremost, the most important factor to consider is your budget; it determines which RAM you can afford and which RAM is out of your range. Let’s face it, building a Ryzen 9 7900X rig is not cheap, especially if you plan to use the best CPU cooler along with the best motherboard for it, which you likely are going to use.

So, when selecting the Top RAM for Ryzen 9 7900X, we scrutinized them heavily based on price, making sure that no RAM is overpriced and each one of them offers good value in their own price bracket.

For example, take the Corsair Vengeance RGB, the RAM costs north of $300, which is quite a lot. But, it is capable of running at 7200 MHz without manual overclocking, which is an insane number for frequency.

The point is, even if memory is expensive, it doesn’t have to be overpriced, and that’s what we consider the most when selecting our RAM.

Transfer Rate and Timing Latency

It goes without saying that performance matters a lot. After all, who would deliberately go for a lower-performing RAM when knowing there are better alternatives out there? But, there are a couple of factors out there that should be considered when talking about just the sheer performance, namely transfer speed and timing latency.

Most people are well aware of the transfer speed, which refers to how many transfers the RAM can make in a second, and consequently, the higher the transfer rate, the better the RAM is.

But, many people overlook the timing latency, which is just as important, if not more important, than the transfer rate. It determines how many clocks the RAM is going to wait for during various operations. Timing latency is written as a series of four numbers separated by a dash. For example, the Corsair Vengeance has a timing latency of 34-44-44-96, where the first number indicates its CAS latency, which basically tells us that this particular Corsair Vengeance RGB RAM is going to wait for 34 clocks before delivering the requested data.

Unlike the transfer rate, the lower the timing latency, the better the RAM is in terms of sheer performance. To sum it up, we selected the RAM that offers the highest possible transfer rate while also maintaining a lower timing latency at a given price point, ultimately ensuring good value for money and extreme performance.

Power Consumption and Thermal Efficiency

Another important factor to keep in mind when selecting the best RAM for Ryzen 9 7900X is the power consumption and thermal efficiency. DDR5 RAM, in general, is more efficient than the last-gen DDR4 RAM. For starters, the standard input voltage for DDR5 RAM is 1.1V, which is 1.2V for DDR4.

Additionally, since the Ryzen 9 7900X can only work with DDR5 RAM, there wasn’t an issue with power consumption, to begin with. But, the power consumption of RAM shouldn’t be looked at the same way we consider the power consumption of other components. By that, we mean that whether the input voltage is 1.1V or 1.4V, it is not huge enough to affect your electricity bill.

However, it greatly affects the overclocking potential of the RAM, which is why we considered it a lot when picking our RAM. So, if your RAM is running at 1.25V, you have more room to overclock it than if it is running at 1.4V.

Not only that, but the power consumption also affects the RAM’s thermals, and if it does not incorporate a good heat spreader, it might suffer from thermal throttling and reduce its performance figures.

That’s why we emphasized power consumption and thermal efficiency a lot because they can basically make or break the RAM’s performance.

Build Quality and Aesthetics

In 2022, it’s highly unlikely that you will find a DDR5 RAM that suffers from build quality unless you go with a cheap knock-off that costs a fraction of what most DDR5 RAM costs.

With that said, it is still important to consider that our selected RAM can stand the test of time and are durable enough to withstand general wear and tear. Also, if the RAM does not incorporate a good heat spreader or a case, dust and humidity can easily build up over the memory chips, which can degrade their performance in the longer run.

Additionally, we considered the aesthetics as well. After all, you’re building a Ryzen 9 7900X rig, and with such a high-end rig, you should be able to show it off to your friends. So, while RGB is not an essential feature, we still consider it a plus point for those RAM who have it.

Compatibility

Last off on the list is compatibility, which is just as important as the other factors. Whenever you’re buying RAM, you need to keep in mind what type of components it will be working with, which, in our case, is the Ryzen 9 7900X. So, every RAM we selected offers enough power to nicely go along with the R9 7900X, with no room for memory bottlenecks.

In addition to that, it is also important to consider the physical compatibility of the RAM. If you’re planning to build a gaming rig with a small form factor, then you won’t have much room to accommodate large components. In that case, you need low-profile RAM, such as the G.Skill Flare X5 Series, to fit into your case.
