DDR4 2400 Vs 2666 MHz Ram Full-On Comparison With Top Picks


DDR4 2400 vs 2666

From the hard drive, the data is been taken by RAM and this includes the programs and games. The component has to hold this information while you are enjoying that program or game. And that’s one main reason why the RAM memory usually is much faster than what your standard hard drive shows. The same goes for SSD.

That’s one reason why RAM is getting faster with the passing time. But the point here is that does a faster Ram actually means better performance. Is it really necessary to have a 2666MHz instead of a little lesser 2400MHz?

Our today’s comparison is going to be the answer to that confusion. It’s about who’s actually better between the DDR4 2400 vs 2666 and which one should you be investing your money on.

The Better Choice?

Clearly both have their strong and weak points to show when we break down them into a battle comparison of DDR4 2400 vs 2666. However, it’s also pretty obvious that higher MHz definitely will make more sense to have a powerful component supporting you with faster speed. And for that reason alone, it’s surely a smart idea to go for the 2666MHz with that extra cost to pay.


If you are looking forward to something capable enough on handling challenging applications, then DDR4 2400 will still be able to serve you right. It’s a nice RAM that can give you satisfying results even when you use several programs at the same time. For gaming, it has received lots of praise, and also it fits into the programmer’s needs. You can enjoy universal support with any type of motherboard.

However, for the extreme fast gaming performance and a superior multi-tasking feel, the RAM 2666 will still be some steps ahead. It’s the upgraded version that will not need any XMP for you to operate. It’s also known for extending the battery life of PC.


To be honest, the winning spot goes to RAM 2666 but there’s still no dramatically added benefit that you are getting with it. The price that you pay extra for the 2666MHz is basically why you are having some upgraded features not present with the less MHz versions. So, you must be measuring things according to your needs. If decent gaming and programming focused RAM will be just enough in a budget-friendly price, then you don’t need to pay extra for the . However, if you don’t mind that slightly more price paying, then go for the higher feature offering version.
