Frequency: 2400MHz | XMP Ready: No | CAS Latency: 16 | Auto Overclocking: Yes

Corsair is at the pinnacle of RAM kits and there should be no surprise in seeing a Corsair product at top of this list. These Corsair Vengeance series DDR4 kits render better performance through while providing faster speeds at the same time with their 2400MHz operating frequency. This specific model consists of 2x 8GB of RAM.

Corsair Vengeance kits for laptops were originally released for the 6th generation but they are very compatible with the newer generations 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. 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.

Overall, these RAM kits check 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.

Kingston is the biggest memory manufacturer in the world and definitely it produces some of the fastest type of RAM modules. This is the best high-speed memory module that you can buy to speed up your gaming laptop it even comes close to its bigger brother the “Kingston HyperX FURY” desktop ram in terms of speeds.

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 the 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.

Frequency: 2666MHz | XMP Ready: Yes | CAS Latency: 18 | Auto Overclocking: Yes

Patriot Viper 4 Series is a performance series and is the best choice for gaming laptops or other high-end systems. They might not be very famous but undeniably the best in terms of value. It is a single stick 16GB RAM running at the high speed of 2666MHz. The RAM kits are XMP 2.0 ready and are automatically overclockable out of the box as well.

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, 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.

Overall, ignoring the compatibility issues and somewhat high CAS latency, this RAM kit is a fine choice for high-end users.

Hynix is quite close to Kingston in the race of memory manufacturing and a lot of RAM kits use their memory as well. TimeTec Hynix is very popular among users who use their laptops for performing productivity tasks, i.e. these DDR4 memory kits are for the professionals out there. It runs at a high speed out of the box at 2666MHz. It will give you the performance boost that you needed with a reasonable price tag to match. Moreover, these RAM kits run at 1.14V instead of 1.2V, thus resulting in higher efficiency which in turn leads to better battery life.

Like the Corsair RAM kits, these ones also come with a lifetime warranty. One thing that must be noted with this RAM kit is that they have a CAS latency of 19, which is quite much higher than most of the other DDR4 RAM kits for the laptops. Another unfortunate thing is that it has very limited compatibility, so you will have to be completely sure that you are buying this for the right device.

Overall, these RAM kits are a decent choice to gain performance if your device is fully compatible with them as these modules offer lower power consumption as well, ultimately making them an eco-friendly choice.
