Aorus RGB Memory DDR4-3733 | Review

Aorus RGB Memory DDR4-3733 | Review

When it comes to RAM memories, perhaps Aorus is not the first name that comes to mind: Gigabyte entered this market only in 2018, but it immediately offered good quality products, improving them over time until it was able to offer them. to compete with those of the most famous brands. Today we take a look at the Aorus RGB Memory DDR4-3733, a new proposal from the range of memories of the Taiwanese company.

Certainly the name will not be the most attractive, but it immediately highlights the main feature: the maximum frequency of 3733MHz. The memory kit we tested offers 16GB of memory (2 x 8GB modules), RGB lighting on the top, and dark gray metal heatsinks with the Aorus logo. The RAM works at a base frequency of 2666MHz with timing 20-19-19-43 on the AMD platform and 19-19-19-43 on the Intel platform, but obviously they support XMP technology that allows you to reach 3733MHz with timing 18-22 -22-42 at a voltage of 1.4 volts.

The memory chips used by Gigabyte are 8Gb SK Hynix D-die, in addition the Aorus RGB Memory DDR4-3733 supports Aorus Memory Boost technology which it allows to bring the frequency up to 3800MHz. If you have a Gigabyte Aorus motherboard, just go to the "tweaker" tab, select the XMP profile and enable Aorus Memory Boost.

RGB lighting is managed by a dedicated microcontroller and is compatible with RGB Fusion 2.0 . The Aorus RGB Memory DDR4-3733 kit supports 12 lighting modes, 5 of which are exclusive to the RAMs of the Aorus family; you can choose from the most common effects, and the RGB Fusion 2.0 software allows you to synchronize the lighting between all compatible components such as RAM, motherboards, video cards, heatsinks, cases and Aorus-branded peripherals.


We put the Aorus RGB Memory DDR4-3733 kit to the test with some tests, to evaluate its performance in three different scenarios: base frequency, with XMP active and in overclocking. The tests were carried out on an AMD platform, equipped with a Ryzen 9 5900X processor and Gigabyte X570 Aorus Pro motherboard.

If you do not go to change the settings in the BIOS, the RAM works at 2666MHz with 20- timing. 19-19-43, while if you enable XMP they go up to 3733MHz with timing 18-22-22-42. In overclocking, without actively cooling the memories, we managed to reach 4200MHz with timing 18-22-22-42, the same as the XMP profile. During our tests we were also able to bring the memories up to 4266MHz and 4333MHz, but the system was unstable and several times we were faced with blue screens.

The benchmarks show a fairly predictable scenario: with increasing frequency increases performance. The biggest gap is obviously in the passage from 2666MHz to 3733MHz, while between 3733MHz and 4200MHz the difference is small and in some cases nothing, as happens for F1 2020: in the first scenario, the frequency increase guarantees a 13% performance increase. , but bringing the RAM to 4200MHz does not increase the framerate.

The memory test of Aida 64 highlight even more the differences between the three settings used: enabling XMP improves performance by about 40% copy, read and write and reduce latency by 9%, while 4200MHz overclocking guarantees 12% more read and copy performance and 5% less latency. The difference in the writing test is smaller, only by 3%.

Finally, the difference in the two decompression and compression tests of 7-Zip is smaller, where the frequency change has little effect: in the first case you go just over 1%, in the second it goes from 4% to 6%.


The Aorus RGB Memory DDR4-3733 kit is a good solution for those looking for match to your configuration, be it Intel or AMD; the maximum frequency of 3733MHz is ideal for both Ryzen 5000 and Ryzen 3000, since the relationship between frequency of the Infinity Fabric, frequency of the memory controller and frequency of the memory itself remains 1: 1: 1 and allows to have the maximum performance.

During our tests, we were also pleasantly surprised by the overclocking possibilities: without spending too much time tweaking the various available settings we were able to reach and keep stable 4200MHz, maintaining the same timings as the XMP profile despite having a frequency of almost 500MHz higher. With these premises, it is likely that those who are more experienced in overclocking will be able to push them even higher, without having the stability problems that we have encountered at higher frequencies.

In conclusion, if you are looking for a new kit from 16GB of DDR4 RAM that offers both good performance and excellent aesthetics, this Aorus kit is certainly a valid option, even considering the price of about 120 euros at which it is possible to find them online, in line with that of competing proposals equipped with same characteristics.
