Product Features:

 

Up To Double the Bandwidth

DDR5 allows for up to double the bandwidth of DDR4, reducing a memory bottleneck. Content creation, gaming, and more will benefit from these rocket-fast speeds.

High Performance

DDR5 has other internal improvements that lead to better overall performance. Make the most of your memory and reach the next level in gaming with these new technologies.

Higher Capacity

DDR5 can have up to four times the capacity in the same space, making sure you never run out of memory again. More is better, especially if you’re juggling sixteen cores or more.

Compatible & Reliable

DDR5 also has improvements to error correction, making sure your experience is consistent and reliable. Further, our memory meets all JEDEC memory standards, so it’s easier than ever to upgrade and be on your way. Installation is always simple and easy, too.

User Manual

 

Sabrent has been hard at work for releasing its new 16GB and 32GB memory modules from the DDR5 kind, which are great to be used in the latest Intel Alder Lake platforms. These supply quite a bit of bandwidth even at the 4800MHz operating speed, while requiring much less voltage of about 1.1V. At least with the Rocket series, Sabrent designers are not a fan of RGB-enabled modules but goes with the more professional look we have seen with their SSDs as well.

 

The 32GB kit we are going to review today is not packaged as a two-module SKU; Sabrent is selling these modules individually, each coming in a nice, sealed cardboard enclosure:

 

 

 

On the frontal part of the slim cardboard packaging, we will note a photo of the module, its operating frequency but also the capacity:

 

 

 

On the side, Sabrent notes that this kit was made especially for desktop computers:

 

 

 

On the back, we will find another photo of the module, along with the Rocket logo, the model code name but also its serial number:

 

 

 

After removing the top packaging layer, we will find inside another cardboard enclosure, which opens up like a small book:

 

 

 

The module is kept secure inside with foam material, but also some documentation is supplied as well:

 

 

 

The installation process is easily described inside the manual:

 

 

 

This is the first time we are seeing a heatsink construction of this type on a memory module; Sabrent has built thin pure copper foils almost as large as the whole module, which we have first seen on M.2 SSDs. These thin foils do help greatly with heat evacuation and manufacturers can also customize their outside layer with different prints; in this case, we have the Sabrent logo in the middle and more info on the sides:

 

 

 

Taking a closer look on the left side, we will note the name of the product series, the type of RAM modules but also the stock operating frequency; also, here we will note that the module was developed by Sabrent in the USA:

 

 

 

The module capacity is printed on the right, together with a Rocket branding logo:

 

 

 

While looked from the top, we will note how thin the module is, given the new heatsink solution:

 

 

 

Even in this case, Sabrent was able to fit some extra info on the frame:

 

 

 

The back side of the heatsink does feature a Rocket logo in the middle:

 

 

 

A closer look does feature the product serial number, code name and we will be also noted that the modules were manufactured in Taiwan; the 16GB Sabrent DDR5 4800 module is single-sided, the whole set of components being available only on the front side:

 

 

 

Here is a photo of the modules installed in our test system, ready for benching!

 

 

 

Test Setup

 

CPU: Intel i7-12700K @ Stock

CPU Cooler: be quiet! Pure Loop 240mm AIO

Motherboard: EVGA Z690 CLASSIFIED

RAM: currently tested kit

Video: XFX Radeon RX 5700XT Ultra THICC III

Power Supply: Cooler Master 850W

SSD: Silicon Power US70 1TB PCIe 4.0

Case: Cooler Master ATCS 840

 

The pre-programmed timings and frequencies can be also found by using AIDA64; the DRAM IC manufacturer is listed as SK hynix:

 

 

 

As you have probably noted from the first screenshot, these modules do not come with a pre-loaded XMP profile, so the motherboard will automatically go for the most compatible timing set after the first boot-up. Our Z690 CLASSIFIED from EVGA went for the tightest timings involving the 4800MHz frequency, which are 40-40-40-76; we then went ahead and tested with TM5 the stability:

 

 

 

Naturally, we then went ahead and checked out how far we can go and in order to be on the safe temperature/stability side, we upped the voltage to a maximum of 1.25V as well; 5200MHz was perfectly doable, at the exact same timings!

 

 

 

We were quite surprised to see that the 5400MHz test has passed as well:

 

 

 

Well, this is interesting…the kit was marketed at 4800MHz but can do 5600 this easy?

 

 

 

To our surprise, at the stock clocks 5800MHz was perfectly doable as well:

 

 

 

This is a new one! 4800MHz-rated kit running 6000MHz fully stable at stock timings…there you have it:

 

 

 

6000MHz was quite an impressive end of the road, because with 6200MHz we started having issues booting up.

The Rocket DDR5 4800MHz U-DIMM memory modules are Sabrent’s first attempt of products in this category and boy…they quite deliver! While not having a preloaded XMP profile, they come with the compatible JEDEC profiles, which each and every motherboard supporting the DDR5 standard should be able to work with it. In terms of performance, while they are marketed at 4800Mhz, they can be overclocked to impressive speeds of about 6000MHz, so a lot of free performance without spending extra money on a rated DDR5 kit with those same speeds!

 

The modules do not come with flashy LEDs but employ a more professional look, in-line with their line of SSDs; thanks to the slim foils of pure copper, the heat dissipation is quite efficient and because of the low width of the modules, there is enough ventilation space even if you sport a 4-module setup.

 

Each Rocket DDR5 16GB 4800MHz module can be purchased from Sabrent website for about $179.99 (at the time of the review).
