Sabrent Rocket 32GB (2x16GB) DDR5 Memory Kit Review

Memory by stefan @ 2022-06-01

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!

Test Setup and Test Results Part I

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.
