RAM being primary storage is one of the most important components of a computer. To maintain the performance and stability of a system, it is necessary to have sufficient RAM, whether it be 8GB or 16GB in total. Modern RAMs have lots of features and factors that decide which type of RAM is best for your usage. Not everyone is tech-savvy and for this reason, we have come up with a tier list for the best DDR4 RAM for laptops.

Corsair Vengeance DDR4 RAM for laptops were originally released for the 6th generation but they are very compatible with the newer generations, Ryzen laptop as well and offer great prices as well. No BIOS changes are needed to be able to take advantage of the overclocking, as it is auto-overclockable. As for the voltages are concerned, these kits run at 1.2V at the max speed. On a related note, we have a detailed guide on how to overclock your RAM for Ryzen systems if you’re running a modern desktop PC.

These particular kits run at a frequency of 2400 MHz, however, kits with up to 4000MHz are available, although your system must be fully compatible before running those high-frequency RAM kits and those kits are a lot pricier as well. However, they are not as fast as their desktop offerings such as the Corsair Vengeance LPX series. You can read our guide on how to overclock RAM using XMP to get the most out of this kit.

This is the best value DDR4 RAM for laptop that checks high speed, lifetime warranty along with a competitive price, which is why we are awarding this ram as the “sweet spot” for almost any type of laptop.

The Impact RAM modules come in different speeds and capacities, with the 16GB variants representing the best value. These are also auto-overclockable straight out of the box and run at a voltage of 1.2V. But beware, these modules won’t be able to reach 1.35V.

This is undeniably one of the fastest RAM kits out there and truly utilizes the capabilities of DDR4 to its fullest. The kits are available with a data rate frequency of up to 3200 MHz and are XMP ready, which means that you do not need to adjust memory timings for overclocking. All you have to do is select various predefined profiles to overclock these RAM kits. The only thing that might steer you away from this high-performance RAM is the cost. These are not such a great value when compared to other RAM kits due to this very reason.

Moreover, the RAM kits come with heat-spreaders as well, which result in less wear and tear to the kits, as the heat is dissipated efficiently. However, due to this increased thickness, these RAM kits might not fit into your laptop or notebook, so make sure to check the physical compatibility thoroughly. Apart from the form factor compatibility, you should also check the specification compatibility, as there are a lot of reports being made about these kits being incompatible with many laptops.

Does RAM Speed Matter?

A lot of users have this question since the topic is quite complicated in nature. At the end of the day, we don’t want to give a vague and non-descriptive answer, but it definitely depends upon the user. If you want a more detailed analysis, check out our opinion piece on RAM Speed – does it matter?

We have to look at the different scenarios individually to gauge the effect of RAM speed. When it comes to gaming memory, a lot of games aren’t very particular about RAM frequency. In fact, it doesn’t have a drastic effect on the average framerate in a lot of games. However, some games are a bit more particular about this. PCs with higher capacity and higher clocked RAM perform better in a few particular games. In terms of productivity, RAM speed has been known to make a difference. Especially with video editing, systems with faster memory tend to render video quicker as well. Even in minute tasks such as transferring files, faster RAM is a bit more appreciated. You should also take a look at our opinion piece on 64 GB RAM – Is it worth it?

If you’re going all out with a high-end rig then sure go with 3600+ Mhz to get that slight increase in performance. But for most people with a more constricted budget, we recommend focusing on other areas of performance first such as the GPU and the gaming CPU. For most mainstream builds, 2666 Mhz or 3200 Mhz seem to be the sweet spot. The slight mileage you get in performance going beyond that is barely worth it.

Frequently Asked Questions

Is 32GB RAM overkill?

Currently and Unlike 4gb DDR4 RAM, 32GB of RAM can be classified as overkill for the regular user. If your daily use revolves around web browsing and word processing, then even16GB of RAM is way more than you could ever need. Even gamers should be content with 16GB of RAM as of right now. However, if your use includes video and photo editing and productivity tasks of that nature, then 32GB of RAM is recommended since those tasks do eat up quite a bit of memory. Any serious productivity-focused machine should be equipped with at least 32GB of RAM in 2021.

Can I mix RAM speeds?

Technically, yes, you can mix RAM speeds without encountering any significant problems, although this is not recommended for a couple of reasons. Mismatched RAM speeds can sometimes cause stability issues and might even prevent your system from booting up. In theory, mismatched RAM speeds are automatically synchronized to the slower speed of the two, but sometimes this is not the case. Therefore, it is always recommended to buy RAM sticks of the same speed and latency.

What’s more important RAM speed or size?

Both RAM size and RAM speed are important in their own rights. As far as RAM size is concerned, the basic rule is that you should have more RAM in your system than you can use in any scenario that you encounter on a daily basis. For most people, 16GB of RAM is plenty and for productivity-focused machines, usually, 32GB is recommended. As far as speed is concerned, it is less important than the RAM size in terms of critical system stability, but it is still important if you want a little bit more performance in applications like games.

Is higher MHz RAM better?

Generally speaking, higher MHz RAM is better due to the faster rate of transfers, but that is only one side of the story. There is a clear point of diminishing returns in RAM speed as well, so it does not make sense to spend a lot of money for minor increments in performance beyond a certain point. Moreover, you also have to take into account the CAS Latency (CL) of the memory modules, which acts as sort of a counterweight to RAM speed. Higher CAS Latency is detrimental to the module’s performance even if the MHz rating is high.
