Good

This 4GB RAM is 2666Mhz SDRAM with latency of CAS 19. It can function as 2400Mhz RAM with latency of CAS 17 in case you already have a 2400Mhz RAM in another slot or your bus don't support 2666Mhz as in case of AMD laptop CPUs which only upto support 2400Mhz. You can install this RAM in your laptop only if you have an extra empty SODIMM slot or if your current RAM is damaged and you want to replace it. Many laptops nowadays come with soldered RAM which can't be removed or upgraded and in such cases, this RAM is not to be bought. Also, one must take care that the RAM slot is DDR4 and not any other type as DDR4 RAM will not fit in DDR3 or DDR2 slots. Dual channel support- There is a misconception that dual channel requires 2 identical RAM of same size, same brand and latency. This is only partly true. One van easily install 4Gb RAM along with another 8GB RAM (or even 16GB RAM) and still get a partial dual channel mode called "FLEX" channel where 4GB from both RAM sticks will be in dual channel while the extra RAM will be in single channel. The performance difference between dual channel and flex channel is minimal at about 2% FPS reduction when playing games. But the cost difference is about Rs 1300. If one doesn't need 16GB RAM, then installing 8+4 = 12GB RAM is enough and one doesn't have to fear loss of dual channel and save some money in the process. I myself have installed this RAM along with another 8GB SAMSUNG RAM. One has to only ensure that that CAS latency and Mhz speed to be identical to ensure maximum performance in flex channel mode. The performance of Crucial RAM and SAMSUNG RAM appears identical in all the benchmark tests I have run. The only negative is that Crucial only offers 3 year warranty whereas companies like ADATA offers 10 year warranty.

Worked just fine to extend the RAM on my Synology NAS

Installée dans mon NAS Synology, cette barrette Crucial 4 Go a été reconnue immédiatement. Aucun souci de compatibilité, le système tourne parfaitement. Idéal pour une petite upgrade simple et fiable.

My laptop had a spare slot for more memory, so I eventually got round to filling it. I opened the laptop slotted the memory in, closed up and it worked as it should. Now the laptop runs somewhat faster than before having doubled the RAM from 4Gb to 8Gb. Very good and very pleasing. It's worth noting that I do not use this laptop for gaming, because it does not have a gaming GPU, so extra RAM would have little effect on its gaming capabilities.

Habe den RAM als Erweiterung für mein Synology DS224+ gekauft – wurde sofort erkannt und läuft absolut stabil. Der Einbau war unkompliziert und in wenigen Minuten erledigt. Seit dem Upgrade läuft das NAS spürbar flüssiger, gerade bei mehreren gleichzeitig laufenden Diensten. Gute Qualität, fairer Preis und zuverlässige Leistung – genau das, was man sich von Crucial erwartet. Klare Kaufempfehlung für alle, die ihr NAS aufrüsten möchten!

Good memory for great price! Fits even in Synology DS423+ (expands memory to 10GB).
