The release of the Intel 12th generation Core and AMD Ryzen 6000 chips have finally brought DDR5 memory to the mainstream PC market, bringing with it a slew of benefits. For this review, we will be looking at the Lexar Ares OC DDR5  desktop memory kit, which is specced at 5200MHz.

The release of the Intel 12th generation Core and AMD Ryzen 6000 chips have finally brought DDR5 memory to the mainstream PC market, bringing with it a slew of benefits. For this review, we will be looking at the Lexar Ares OC DDR5  desktop memory kit, which is specced at 5200MHz.

Lexar indicates that their new memory kit is optimized to pair with the latest Intel Core processors. We will also be comparing it to other DDR5-5200 kits (like the recently reviewed Kingston Fury Beast) and benchmarking it at DDR5-4800 to find out if the upgrade and additional cost of DDR5-5200 are worth the higher price tag.

Lexar Ares OC DDR5-5200 Features

DDR5 debuted in 2021 as the replacement for DDR4, which had been the mainstream standard since 2015. Among the new benefits of DDR5 technology (specifically with this Lexar kit as well) are built-in on-die ECC, and real-time data error correction (to improve stability and reliability when you push the memory to its limits).

Moreover, its built-in Power Management IC (PMIC) means better power control and power delivery when operating at 1.25V (a low voltage XMP Profile). This will help improve overall power efficiency.

Higher performance is also a huge advantage with DDR5, as Lexar indicates an improvement of more than 1.6x the bandwidth compared to DDR4 memory.

The Lexar Ares OC DDR5-5200 desktop memory kit is designed specifically for enthusiasts, gamers, overclockers (as its product name indicates) and creative applications. We will be reviewing the 32GB kit via two 16GB DIMMs. Currently, it goes for $250 on Amazon, which makes it a bit pricier than the Corsair Vengeance (on sale at $198 on Amazon) and the Kingston Fury Beast (on sale at $185 on Amazon), and slightly less than the XPG Lancer ($279 on Amazon).

These prices are certainly higher than its DDR4 predecessor; however, prices seem to be driven down as they become more mainstream adopted. In addition, the Lexar Ares DDR5 will be on sale during the Amazon Prime Day promotion from July 12-13, 2022, for $199.99.

As far as its design goes, the Lexar Ares OC features a slick-looking aluminum build with a nice heat spreader to keep it running cool under pressure. It feels sturdy, well-made, and simple to install. The kit is backed by a lifetime warranty.

Lexar Ares OC DDR5-5200 Performance

We use our self-built StorageReview desktop to test DDR5 memory; its specifications are as follows:

The Lexar Ares DDR5-5200 kit under review is two 16GB modules (32GB total). For perspective, we benchmarked it at DDR5-4800 (no XMP) and DDR5-5200 (XMP I and II), using the following settings:

  • DDR5-4800 CL40-40-40-58 (no XMP)
  • DDR5-5200 CL38-38-38-60 (XMP I)
  • DDR5-5200 CL40-40-40-61 (XMP II)

The XMP II timings at DDR5-5200 are slightly looser than they are at our motherboard’s default settings. That said, the timings are essentially the same between DDR5-4800 and DDR5-5200, so the effective latency should go down while operating at the higher frequency.

We are comparing the Lexar Ares DDR5-5200 memory to the following kits and settings:

  • 32GB (2x 16GB) Kingston Fury Beast
    • DDR5-4800 CL40-39-39-58 (no XMP)
    • DDR5-4800 CL38-38-38-57 (XMP II)
    • DDR5-5200 CL40-39-39-61 (no XMP)
    • DDR5-5200 CL40-40-40-61 (XMP II)
    • DDR5-4000 CL32-32-32-54 (no XMP; would not run at rated DDR5-4400 without XMP)
    • DDR5-4400 CL36-36-36-59 (XMP II)
  • 32GB (2x 16GB) XPG Lancer RGB DDR5-5200 CL40-40-40
    • DDR5-5200 CL40-40-40-61 (no XMP)
    • DDR5-5200 CL38-38-38-60 (XMP II)
  • 32GB (2x 16GB) Team Group T-Force Delta RGB DDR5-5200 CL40-40-40
    • DDR5-5200 CL40-40-40-61 (no XMP)
    • DDR5-5200 CL40-40-40-61 (XMP II)

Note that it’s certainly not an apples-to-apples comparison, as we’re using different memory sizes and DIMM configurations.

SiSoftware Sandra 2021

First up is the SiSoftware Sandra 2021 suite where higher numbers are better in all subtests. In this test, we will look at the kits running at DDR5-5200 both with and without XMP II profiles engaged. Note: The Corsair kit is excluded from this group since it can’t run at DDR5-5200.

The Lexar Ares DDR5-5200 memory displayed better performance with XMP I (compared to XMP II and no XMP), showing solid performance across the board with a leading overall memory score of 2.53kPT (XMP I). That said, without XMP, it had the weakest results with an overall memory score of 2.38kPT.

7-Zip Compression Benchmark

The 7-Zip file archive tool features a very useful built-in compression benchmark. Here, we ran 10 passes using a 128MB dictionary size and all 24 CPU threads of our Core i9-12900K; higher numbers are better. Like the SiSoftware Sandra, we will look at the Lexar Ares DDR5-5200 kit and compare it to the other DDR5-5200 kits first.

The Lexar Ares performed better than the Kingston Fury and Corsair in both XMP I and XMP II engaged. For example, it had a compression resulting rating of 102.092 GIPS with XMP II, which was a 4% faster than the Kingston and Team Group kits and a 3% improvement over the XPG.

However, it fell behind slightly in some of the results without XMP (from 5-6%), which was true during the SiSoftware Sandra test as well (seen above).


The Lexar Ares OC is a solid DDR5-5200 memory kit that had a great showing during our benchmarking. Unsurprisingly, it performed its best with XMP I and II enabled where it was faster than the DDR5-5200 kits we tested from Kingston, Team Group and XPG (though it fell a bit behind without XMP).

The results of our tests also demonstrated the benefits over the DDR5-4800 standard, specifically during the 7-Zip compression benchmark. Like in our other reviews, this proves that the cost increase of DDR5-5200 technology over DDR5-4800 is well worth it.

Lexar Ares OC DDR5 feature

As far as its design goes, the Lexar Ares is a solid, slick-looking memory kit and would definitely look great in a gaming rig. It also features heat spreaders that generally keep it cool during heavy workloads and comes embedded with other important features like built-in power management, on-die error-correcting coding, and a low CAS latency rating of CL38-38-38-74 (with XMP 3.0 support).  The Lexar Ares OC, however, does not feature any RGB lighting capabilities, so if this aesthetic feature is important to you when building a new system, you should probably consider the XPG or Team Group kits.

Overall, we certainly recommend the Lexar Ares OC DDR5-5200 memory to those looking to get the most out of their high-end PCs.
