Sabrent Rocket DDR5 4800 MHz, our kit pushed to 6000 MHz!

Today we test the memory in the Hardware Kitchen Sabrent Rocket DDR5 4800MHz U-DIMMreference SB-DR5U-16G† Note that the brand does not offer its modules in kit form, but only individually. So we received two 16 GB modules here to form a 32 GB kit. We will therefore see during this test what this kit of Sabrent really worth it. Indeed, remember that the brand is just launching into the RAM memory market.

Sabrent Rocket DDR5 4800 MHz: our test

As we just said, the company will enter the RAM market only after it takes a good place in the SSD market with quality products. Therefore, we expect no less for its RAM. The brand first launched DDR4 SO-DIMM modules for laptops in early April and announced its DDR5 U-DIMM modules for our desktop PCs a month ago. Specifically, we are here on modules announced in DDR5-4800 CL40-40-40-76. In terms of warranty, we can read on the brand’s website for a period of one year, but it can be extended to 5 years by registering the purchase.

There is a specificity to the modules compared to the kits of other brands that may be surprising. Here we do not have a preloaded XMP profile, therefore the brand announces “only” DDR5-4800, which corresponds to the JEDEC standard. On the other hand, once in place on the motherboard, the latter will provide a profile on its own. For example, our ASUS ROG MAXIMUS motherboard simply offers a DDR5-6000 CL38 profile. So a higher frequency, but also a lower latency. This in itself is a very pleasant surprise, as these modules are much more efficient than at first glance!

Sabrent Rocket DDR5

In terms of pricing, Sabrent does not sell its modules in kit form, but only with individual modules. The Sabrent brand is mainly found on Amazon and the 16 GB module is sold for 206 euros, yielding a 2 x 16 GB kit for 412 euros. The brand’s website lists the 16 GB module for $179.99 and the 32 GB module for $299.99. In practice, Amazon does not yet offer the 32 GB module at a “normal” price as it is currently the case displayed at 794 euros


The RAMacronym for Random access memory, is a random-access memory used to store the information necessary for the processor to function. The working environment is loaded into RAM to take advantage of the maximum speed, is synchronized with the processor clock, and the results of the recurring operations performed are written there. The oldest data is simply ejected as it is written to it. The RAM is not a storage medium as the memory is volatile, once the bar is no longer powered it loses all the data not stored on the hard drive hence it is important to shut down your computer properly so that the RAM on the last emptied. If you don’t, your changes may be lost. RAM, to be efficient, communicates at a particularly high speed with computer organs, this value is calculated in nanoseconds. It is necessary to choose speed over size unless you are used to having many open applications or very greedy applications. Today, 8 GB of memory will be enough for classic use (including office automation and light games), but 16 GB will be preferred for gamer use.


packaging

Therefore, to talk quickly about the box and more generally the packaging, the modules arrive in a small box on a black background. On the front we will have a photo of the module, as well as the brand logo, the references and at the bottom the indication of the size of the module, ie 16 GB in our case. On the back we will have the barcode accompanied by the different standard logos. On the sides we find the references.

Once the box is open, we have a small half cardboard semi-foam bag in which the module is comfortably installed and awaits its fate. We also find a small installation guide illustrated in color.

Visual aspect

Visually, Sabrent remains very simple and uses the same idea as for its SSDs. Indeed, we don’t have an aluminum heat sink, but a simple thin layer of copper that covers both sides of the module and also goes over the top. This copper plate has a print with a black background and copper colors that are reminiscent of the Rocket SSD series. This ensures a minimum of cooling while having a design that is not too raw with visible components. A relatively important aspect at a time when many also choose their materials based on design.

On the top of the module on the right we find the reference and on the left we have the small logo of the rocket, muse of the Rocket ranges by Sabrent also used for SSDs. As you can see for yourself, the design is extremely sober.

Protocol and benchmarks: Sabrent Rocket DDR5 4800 MHz

As we mentioned above, Sabrent modules do not have a preloaded XMP profile. As a result, our motherboard offered us a DDR5-6000 CL38 profile (AEMP, also known as ASUS Enhanced Memory Profile). Sabrent tells us that their modules can easily reach 6000 and even 6200 MHz. Even though in practice we haven’t been able to stabilize our modules at 6200 MHz, OC RAM professionals could still succeed. We will therefore test this profile in DDR5-6000, but also with the basic specifications in DDR5-4800 CL40 to see the difference.

We wanted to use the kit under the Taiphoon Burner software to learn more about the components used, but the software crashes with our memory modules. It will therefore be necessary to be satisfied with the information read by CPU-Z. Here we learn that these are chips from SK Hynix.

SPD

To test this memory kit, we will use the following reference configuration:

We are going to run this memory kit under the following software and games:

  • WinRAR
  • Aida64 Extreme (Memory Read, Memory Write and Memory Latency)
  • 3DMark Time Spy
  • Shadow of the Tomb Raider

WinRAR

Among the famous software WinRAR, our kit from Sabrent does admirably well thanks to the AEMP profile which upgrades our kit to DDR5-6000 CL38. So we go to 39,121 KB/s against 36,920 KB/s if the kit stays in DD5-4800.

AIDA64

Let’s go down now AIDA64† Here our kit tops the list with 95,040 MB/s read and 84,534 MB/s write with the DDR5-600 kit. In DDR5-4800 we are at 76,187 MB/s read and 69,497 MB/s write.

Sabrent Rocket DDR5 Test Read Write

The measured latency is 71.1 ns with the DDR5-6000 CL38 module and drops to 86.1 ns with the original specs.

Shadow of the Tomb Raider

Now let’s move on to a video game that is very sensitive to RAM: Shadow of the Tomb Raider† With our frequency in DDR5-6000 we note an average of 228.6 FPS. The average drops to 219 FPS without the AEMP. Note that at the very bottom of the table we have an average of 208 FPS for the CORSAIR Vengeance RT DDR4 kit in 2 x1 6 GB 3200 MHz CL16.

Mixer Score

to end up with a final chart, let’s average the scores we have and divide the total by three to have fewer colossal values ​​and slightly less difference. Specifically, our Sabrent Rocket DDR5 memory kit comes out on top. However, as you can see, we haven’t upgraded any kit (except this Sabrent) to over 5200MHz yet. But very soon we will also offer you the test of a CORSAIR DOMINATOR Platinum RGB kit at 5600 MHz.

Conclusion: Sabrent Rocket DDR5 4800MHz U-DIMM

Time to finish this memory test Sabrent Rocket DDR5 (SB-DR5U-16G)† First of all, remember that the brand does not sell its modules as a kit, but only individually. So we find either a DDR5-4800 CL40 module in 16 GB or in 32 GB. These modules do not have preloaded XMP profiles, but our motherboard corrects this in a way by providing a memory profile in DDR5-6000 CL38 -38-38 -77 in our case. The card also offers a second profile in DDR5-4800 CL32-32-32-77. Details much more interesting than the DDR5-4800 CL40-40-40-76 which simply corresponds to the JEDEC standard.

Visually, Sabrent is very austere and uses the same principle as its SSDs: the cooling of the chips is a thin layer of copper that covers the module on both sides. So it is visually very sober. But we have to admit that we still hope for future references with aluminum heat sinks, RGB is not necessarily necessary. This is just for aesthetics. Indeed, with a simple thin layer of copper, the modules are very thin and almost give an impression of emptiness when we are used to seeing large modules in place on a motherboard.

In terms of performance, the result inevitably in DDR5-4800 MHz CL40 is not the most glorious as we stick to the JEDEC standard. On the other hand, once the DDR5-6000 CL38 profile offered by our motherboard is applied, the performance becomes very good.

DDR5 memory ICs require less power, with the Vdd dropping from 1.2V for DDR4 to 1.1V for DDR5, resulting in better overall power efficiency. DDR5 modules have integrated voltage management circuits (PMICs), which help regulate the voltage required by the various components of the memory module (DRAM, register, SPD hub, etc.). For server-class modules, the PMIC uses 12 V and for PC-class modules, the PMIC uses 5 V. This provides better power distribution than previous generations, improves signal integrity and reduces noise.


Now to talk about prices, you should already know that this brand can only be found on Amazon. In practice the 16 GB module is sold for 206 euros, yielding a 2 x 16 GB kit for 412 euros. The brand’s website lists the 16 GB module for $179.99 and the 32 GB module for $299.99. As for the 32 GB module, the price on Amazon is not at a “normal” price, as it is currently displayed at 794 euros


Finally, we reward a HC gold medal to this memory kit from Sabrent because of its good performance.
