Frequency: 2400MHz | XMP Ready: Yes | CAS Latency: 14 | Auto Overclocking: Yes

Kingston is the biggest memory manufacturer in the world and definitely it produces some of the fastest RAM kits. This is the best high-speed memory module that you can buy to speed up your gaming laptop. The Impact RAM modules come in different speeds and capacities, with the 16GB variants representing the best value.

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 frequency 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.

Overall, these RAM kits are recommended to any gamer looking for a kick in performance and not worried about the high price.

3. Patriot Viper 4 Series

Our Rating: 9.5/10

  • Comes with heat-spreaders
  • XMP 2.0 Ready
  • High CAS latency
  • Might not fit inside some laptops due to thickness

18 Reviews

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

Patriot Viper 4 Series is a performance series and is designed to use with 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 physical 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.

4. TimeTec Hynix

Our Rating: 8.6/10

  • Great Speeds at 2666Mhz
  • Extremely low voltage at 1.14V
  • High CAS latency at 19
  • Limited Compatibility

76 Reviews

Frequency: 2666MHz | XMP Ready: No | CAS Latency: 19 | Auto Overclocking: Yes

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. this RAM kit is 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 longer battery timings.

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.

5. Patriot Memory Signature Line

Our Rating: 8.0/10

  • Dirt cheap
  • Low Latency at 15
  • Not overclockable
  • Not as fast as other DDR4 modules

22 Reviews

Frequency: 2133MHz | XMP Ready: No | CAS Latency: 15 | Auto Overclocking: No

Last up on our list is the one at the budget side of the market, the Patriot Memory Signature Line. This is a simple module with 8GB of capacity and it runs at 2133MHz, which is somewhat lower than the standard 2400MHz  memory kits you would find in most laptops. Due to the lower frequency, the CAS latency of the RAM kits is quite low at only 15. Moreover, these kits are a lot cheaper than the previously mentioned kits.

Since it runs at a low frequency, the chances are that these RAM kits are very much compatible with most of the laptops. However, the downside of these kits is that they do not have any overclockable support or XMP profile but that can be forgiven, as they are available at such a low price.
