Best Ram for Ryzen 9 3900x – BUYER’S GUIDE


A branded RAM will always be dominant over the local ones as they are manufactured with the highest quality components. Furthermore, a brand wouldn’t compromise on its products nor it will use any sort of low-tier materials.

While on the other hand, if you opt for a local brand RAM, it might be cheaper as compared to the premium brand ones, but it won’t perform and last as the branded one due to the fact that cheap materials are used.

It is highly recommended to never overlook the brand and consider a branded one for long-term benefits.

Memory Clock Speed

The next thing that matters is the speed of the RAM, and you might have come across the “MHz” (MegaHertz) many times: it represents the number of cycles per second.

To be more precise, the 3200MHz simply means 3.2 billion cycles per second. And for higher performance, a higher number of cycles is needed, however, it is not the case every time as some of the models don’t support huge MHz.

Furthermore, there are a couple of other things that also play a huge role in the performance of RAM such as latency, processor architecture, etc.

SDR (Single Data Rate), DDR (Double Data Rate), DDR2 (Second Generation Data Rate), DDR3 (Third Generation Data Rate), DDR4 (Fourth Generation Data Rate), DDR5 (Fifth Generation Data Rate).
