RAM for AMD Ryzen 7 7700X

Table of Contents

Ryzen 7000 brings DDR5 to the fold with its mandatory requirement for an AM5 system. This is one of the main considerations when building a brand new PC for the Zen 4 architecture, especially with the AMD Ryzen 7 7700X. But more than simple tweaks to the system and general hardware options, choosing the best RAM for the Ryzen 7 7700X becomes a priority of stability over potential gains.

Therefore, the first objective is to find a level of customization headroom that would allow DDR5’s memory controller to test its reliability. Things as simple as heat spreader efficiency suddenly become slightly more important, and sensing/monitoring features become crucial to know exactly what the new modules do for the system.

As for frequency settings, the Ryzen 7 7700X shares the same requirements as listed on Zen 4 architecture’s Auto Infinity Fabric settings: 5,200Mhz for the minimum optimization standard, with the FCLK dynamically adjusting with a sweet spot of 6,000Mhz.

CAS latency has much lesser importance for DDDR5. For the most part, all memory kits available already have their XMP/EXPO profiles built to take advantage of the decreased reliance on instruction delays. An effect that is felt even more with the bigger L3 Cache of typical Ryzen processors.

Best RAM for Ryzen 7 7700X

1. Kingston Technology Fury Beast

Kingston Technology Fury Beast Black 64GB 5600MT/s DDR5 CL40 XMP 3.0 Ready Computer Memory (Kit of 2) KF556C40BBK2-64

Verdict

The Kingston Technology Fury Beast never relies on flashy designs, nor are they even close to the best in pure performance. But it wins with a good balance of cost and usability.

Specifications

Memory Type: DDR5 | Capacity: 32GB (2x16GB) | Speed: 6,000MHz | CAS Latency: 40 | Timings: 40-40-40-80 | Voltage: 1.40V | Height: 35mm/1.37″ | Warranty: Lifetime

Benefits

  • Tweaks unneeded. Just plug, set EXPO, and use
  • Low-profile heat spreader
  • Cheap-ish for the product category it slots in

Drawbacks

  • Design is a bit too basic

Buying Options

No special build gimmicks, no customization flairs, and not even a hint of RGB. But what the Kingston Fury Beast offers is standard usability for daily-driving productivity, dipping the user’s toes into the heart of DDR5. Default 6,000Mhz works directly with the intended Ryzen sweet spot, which gives the best optimization for apps that are reliant on memory tuning. Don’t expect any groundbreaking boosts though.

Upon checking its tuning headroom, we noticed that the kits aren’t particularly lenient with CL timings. You can tighten them down a notch, but not really a few points more. The choice is set between regular OC profiles, or turning them down to attempt better CL values. Not exactly the recommended customization. Especially since DDR5 isn’t particularly as sensitive to timings anymore.

No additional points were given to its design. They’re as black and as plain of a heat spreader as you can ever get. No RGB whatsoever. You can translate this to either a boring aesthetic that doesn’t make your AM5 platform visually better or an advantage that makes standard builds maintain a baseline uniformity.

Its low profile allows it to fit anywhere thematically, and physically. In other words, no form factor, basic color combination, or type of beefy air cooler would make it look incompatible.

As much as we’d like to poke holes into its design and use it further, the Fury Beast memory kit is simply more than enough for Ryzen 7 7700X systems to perform their intended tasks with no perceivable delay or use issues. It sits right at the comfortable edge of the sweet spot, without sacrificing too much cost for its DDR5 technologies.

2. Corsair Dominator Platinum

CORSAIR Dominator Platinum RGB DDR5 32GB (2x16GB) DDR5 5200 (PC5-41600) C40 1.25V - Black

Verdict

Corsair’s Dominator Platinum edges out easily in the design department, boasting its nice, thin design, and vibrant RGB. Of course, it still has the soul of its associated product series with great out-of-the-box performance.

Specifications

Memory Type: DDR5 | Capacity: 32GB (2x16GB) | Speed: 5,200MHz | CAS Latency: 38 | Timings: 38-38-38-84 | Voltage: 1.25V | Height: 56mm/2.2″ | Warranty: Lifetime

Benefits

  • As premium as it can look
  • Simple, sleek, and elegant
  • Great out-of-the-box performance

Drawbacks

  • Little OC wiggle room (for its class)
  • 56mm heat spreader height

Buying Options

Moving from plain to stylish, Corsair Dominator Platinum dives straight into the game with plug-and-play usability, without the need to worry about potential compatibility issues. Don’t worry about its lower clocks either, we are still well within the territory of AMD’s target Ryzen 7000 memory frequency optimization line. The Ryzen 7 7700X might be just a tiny, tiny bit more RAM, but it still has enough L3 cache to plow through any potential command line delays or inconsistencies even with a memory frequency of 5,200Mhz.

Theoretically, upping the OC value to its most stable 5,400Mhz could give slightly better performance, but it won’t really be tangible in real-world use. And while 6,000Mhz is not possible, the value potentially lost is never really that high. Certainly, nothing would suddenly cause gaming performance to worsen.

Moving beyond performance, Dominator Platinum sports its usual sleek design that feels very premium with its finish and heft. When plugged into a system, it definitely catches the eye more than just its height.

RGB is also the second reason for its striking appearance. It starts with the square dotted design, which is a departure from the usual bars and lines that other memory RGB configurations have. The lighting itself is also vibrant without looking too bright, adding further to the premium flair that the memory kit’s namesake highly suggests.

3. Corsair Vengeance

CORSAIR Vengeance DDR5 32GB (2x16GB) DDR5 5600 (PC5-44800) C36 1.25V - Black

Verdict

Corsair Vengeance is on the more budget end of the DDR5 competitive spectrum, but it is still just as reliable and stable for both default profiles and that tiny bit of tuning headroom it provides.

Specifications

Memory Type: DDR5 | Capacity: 32GB (2x16GB) | Speed: 5,600MHz | CAS Latency: 36 | Timings: 36-36-36-76 | Voltage: 1.25V | Height: 35mm/1.38″ | Warranty: Lifetime

Benefits

  • Surprisingly decent tuning headroom (we thought it wouldn’t have any)
  • Low-profile heat spreader
  • Stable performance for most settings

Drawbacks

  • Thin heat spreader?

Buying Options

Similar to the LPX, Corsair’s Vengeance modules feature standard performance at standard costs. Even for this rather specific 5,600Mhz CL36 version, it simply does everything that you need a basic memory module kit to do.

In fact, you even have a slight tuning headroom, when we didn’t really expect any at this configuration. It’s just a tiny bit more though, a meager 200Mhz, or a point or two in CL timings. Doesn’t reflect directly on tangible benchmarks, but it does ease the enthusiast’s itch of tweaking whatever they can (quantitatively) tweak within a system.

The T-create-esque edge case heat spreader design is basic, but the patterns actually look great. It does seem considerably thin, however, making us question if part of its very small tuning headroom has to do with this apparent temperature limitation. Most likely not, though.

In conclusion, the Corsair Vengeance is a bread and butter DDR5 memory kit for any basic AM5 system you wish to build. It’s a bit beyond minimum spec by its profile defaults, so that does help the Ryzen 7 7700X a tiny, tiny bit for the workloads where memory speeds matter. But don’t expect anything else to astonish you.

4. XPG Lancer

XPG Lancer DDR5 RGB 6000MHz 32GB (2x16GB) CL40-40-40 UDIMM 288-Pins Desktop SDRAM Memory RAM Kit (AX5U6000C4016G-DCLARBK)

Verdict

The XPG Lancer is the top recommendation for premium-level memory modules for tweaking enthusiasts. You can either choose to use its default max, or set personal tunings with relative ease and stability.

Specifications

Memory Type: DDR5 | Capacity: 32GB (2x16GB) | Speed: 6,000MHz | CAS Latency: 40 | Timings: 40-40-40-80 | Voltage: 1.25V | Height: 43mm/1.69″ | Warranty: Lifetime

Benefits

  • (Relatively) Good latency tweaking potential
  • Resilient stability
  • Unified RGB lightning

Drawbacks

  • Thermal pads not present on PMIC

Buying Options

The XPG Lancer sits right between enthusiast-level and mainstream, with performance reflecting that of a standard product, and having a tuning headroom better suited for higher-end kits. Yes, 6,000Mhz and CL40 are more than enough to put these DDR5 sticks to very good use. But it can even go further, at least in the tweaking department, without you having to worry about whether or not it will boot afterward.

The condition, of course, is that the settings should not be so ridiculous. For best reliability, CL36 is mostly recommended. Though again, as we have repeatedly mentioned, the changes are only ever tangible when doing memory-sensitive productivity workloads. Just set and forget into EXPO if you are mainly into gaming.

Heat spreaders share mostly the same sleek signature as a Dominator Platinum module (even its height), but without the slant edges. It’s a plain four-sided rectangle, but with sexy angles showcasing its black slate and brushed aluminum finish.

We did find it quite strange that the PMIC section does not have thermal pads connecting to the heat spreader. No worries though, as it doesn’t seem to affect the performance of the XPG Lancer at all.

Unified RGB is pretty standard, as far as profile customization goes. We award it additional points at least for its formidable software, which is quite easy to use and offers as many synchronizations as you’d expect.

Overall, the XPG Lancer provides the best of what DDR5 can offer as a new standard. It has the right level of usability, features, aesthetics, and of course, stability under various tunings. Truly the “sweet spot” that amplifies the value of its default memory frequency value.

5. Crucial Desktop Memory

Crucial RAM 16GB Kit (2x8GB) DDR5 4800MHz CL40 Desktop Memory CT2K8G48C40U5

Verdict

Manual OC enthusiasts are in for a treat with Crucial’s basic desktop memory modules. By default, they’re well below Ryzen 7 7700X spec and tier, but when tweaked, they’re as competitive as any RAM on this list.

Specifications

Memory Type: DDR5 | Capacity: 16GB (2x8GB) | Speed: 4,800MHz | CAS Latency: 40 | Timings: 40-39-39-77 | Voltage: 1.1V | Height: 31mm/1.23″ | Warranty: Lifetime

Benefits

  • Black PCB (yes Crucial, we know)
  • Great tuning headroom
  • Reasonably priced

Drawbacks

  • No heat spreader

Buying Options

You’d stay away from the lowest value of DDR5, which is 4,800Mhz. No OC profiles are usable by default, and voltage settings are functionally at the baseline. But with manual overclocking Crucial’s basic desktop memory modules are able to instantly jump a tier or two in performance without the additional cost.

Naturally, with such a basic frequency and timings for DDR5, the Crucial basic memory sticks have a very large tuning headroom. According to our tests, you can reliably set these up to 5,400Mhz, albeit you’ll be stuck with CL40. Basically, you can treat them as default 5,400Mhz sticks with the expectation that you need to change its settings first within BIOS or within AMD’s related tweaking software.

Design-wise, they’re basically fully exposed PCBs. No heat spreader. This means you can plainly see the modules and PMIC sticking out in the open. They’re the cheapest ones after all. But, at least Crucial coated the sticks with a nice shade of matte black.

By having no heat spreader, these modules are devoid of any potential clearance issues as well. Perfect for small form factor systems or downdraft coolers.

This is the cheapest you can ever go for a DDR5 kit. Its non-existent bells and whistles might scare those who have more aesthetic priorities in mind. But for those simply building a reliable Ryzen 7 7700X system, this is the best possible deal within a reasonable price-to-performance target. Provided you are willing to play with the BIOS (or via AMD’s tuning software) enough to get it to the competitive settings you need it to have, of course.

What To Look for When Buying Ram for the Ryzen 7 7700X

Capacity

The sweet spot for price-to-capacity is still 16GB (x2 8GB), but for the Ryzen 7 7700X, 32GB is starting to sound a bit better. You are aiming for a higher-end system after all, and with the multi-tasking capacity of your CPU, you can throw most tasks on either side and continue working with them without having to worry about hitting your Page File. Also, many RAM-hungry games also happen to be CPU-intensive as well, so the pairing should be economically sound. If you can’t get 32GB now, go for two 8GB sticks first, then populate the rest of the DIMM slots later.

Frequency

5200Mhz should be your target minimum, then 6000Mhz max. Ryzen 7000 updates the minimum Infinity Fabric value 1,733Mhz, equivalent to 5200Mhz DDR5. Do take note that Ryzen 7000’s Infinity Fabric (FCLK) should run at Auto. There is no more reason to manually set it at 1 per FCLK, MCLK, and UCLK anymore. 6000Mhz is the maximum sweet spot with its automated tuning, you should preferably aim to increase clock speed as high as possible between the two values.

Latency

DDR5 isn’t too strict on CAS latency. Yes, even if the Ryzen 7 7700X “only” has 32MB of L3 cache. Get your DDR5 up to a good speed you feel you’re comfortable with, and you won’t have to worry about instruction line delays. Even more so if you’re building a system for high-resolution gaming, like for example ultrawide (21:9) 1440p, or widescreen (16:9) 4K.

Dual-Rank versus Single-Rank

Dual-rank memory is faster than single-rank memory. Quite measurable, even if somewhat minuscule. In other words, with modules on both sides, data is processed more quickly, compared to sticks with modules on just one side. Stability is sacrificed for dual-rank this way, however, as single-rank is much better at overclocking. It is also worth noting that dual-rank can optimally use only two sticks with its default OC profiles. If you try using four, you would most likely have to lower clocks a bit to get the PC to boot due to inherent synchronization issues.

Dual-Channel versus Single-Channel

Dual-channel is better than single-channel. Dual-channel effectively doubles the memory bandwidth of the system. As such, there is absolutely no excuse to skip using at minimum two sticks for any PC build. Don’t forget to alternate between DIMM slots when doing so. If you’re confused, just match the colors of the DIMM slots, or look at the labels written on the motherboard. You can also refer to the instruction manual to know how to set RAM in dual-channel. Ignore this tip if you intend to use four RAM sticks anyway.

Pricing

Price considerations for RAM need to be done after the target CPU. As we reach Ryzen 7 7700X levels, it becomes somewhat less justifiable to purchase equally-costing modules. Stick with the higher mid-tier choice for price-to-performance.

Final Thoughts

The Ryzen 7 7700X holds the middle ground of premiere Zen 4 architecture with its 8-core/16-thread configuration and halved 32MB of L3 Cache. Because of this, DDR5 memory tunings will have a slightly, ever so slightly, better effect on the system’s overall performance. It will never show up as reliable benchmark numbers, of course. But for enthusiasts, the very minute positive changes will always be worth the artificial optimizations they provide for any target application.

This does not mean, however, that you have the justification to splurge. The price of the Ryzen 7 7700X is already significantly lower than the two Ryzen 9 offerings, and therefore you should temper your budget expectations according to the investment cost of your intended memory kit choice.
