What is the MHz in memory and why does it matter?

MHz in memory

There are a lot of memory variants today and we often ask others which one to get and what’s the best in the market. Before diving in we have an article regarding SODIMM and LODIMM memory and you can read it here

We see a lot of MHz on memory whether it’s DDR3 with a clock speed range of 800-2133MHz or the latest DDR4 with a range of 2133-3600mhz.


Giving you a background on MHz or Megahertz is a measure of the clock speed on how many times per second the RAM can access its memory and is the same way CPU speed is measured.

Take note that having a faster ram and small storage of ram doesn’t compensate for the ability of speed in a computer. It is supposed to be on the same level as to how big is your memory and how fast.


There’s no point in having faster MHz while having a 2/4GB memory (in today’s time) on your desktop or laptop. The correct format and maximization are having high-speed megahertz and a big amount of memory like 8GB/16GB/32/64GB.

If you’re planning to upgrade your ram kits on your desktop or laptop, then the first thing you’re going to do is check your motherboard model and processor. It will vary on how much and how fast memory it can accommodate with your given components.

Some motherboards only have 2 ram slots on which you have to make the most out of it typically people will put 2 x 8GB of ram to have 16GB of ram and others who are on a tight budget will put 2 x 4GB ram making it 8GB of ram.


AMD processors tend to handle faster MHz on ram up to 3600mhz, unlike Intel which can mostly handle around 2933MHz of ram. They both possess different strengths and architectural build. As per AMD, they rely on the MHz of the ram so it can enhance the processor for a much faster clock speed. On the other hand, Intel doesn’t require higher MHz because they don’t rely on ram but on the processor itself.

There are a lot of factors to consider in terms of RAM speed and storage. But in general, you just have to look into AMD or Intel’s websites on how fast MHz of ram they can accommodate and then look at your motherboards model and also check how fast and how big it can accommodate. It relies on each other on how you can maximize your rig’s full potential and modify it safely.

If your laptop/PC is powered by an Intel processor then most likely you have to resort to lower MHz memory like 2667MHz because almost every high midrange unit can handle 2667MHz and below. But the high-end ones tend to use higher clock speeds like 2933MHz.

AMD laptops/PC can most likely handle 3200MHz of ram and the higher end units can handle up to 3600MHz (which is not ADVISABLE) because you have to overclock and there may be some complications on overclocking but this is not our topic of discussion.

If everything makes sense now, go ahead and purchase your designated RAM sticks and enjoy the upgrade.
