Crucial RAM CT8G4SFRA266 8GB DDR4 2666MHz CL19 Laptop Memory

Works on my pc

I bought an 8GB RAM (part number: CT8G4SFRA266 2666MHz CL19 ) to extend the RAM of my Synology DS220+ NAS. Although Synology says the system supports up to 6 GB of RAM (2GB is included in the original box), the system actually supports more than that. You can add at least another 16GB of RAM to use as a cache to boost up the performance. I have read the previous comments – some claimed that CT8G4SFRA266 does not fit with Synology. This is not true. Mine works very well on DS220+. There are two possibilities why some people found it was not working: 1. They didn't correctly insert the RAM. You will need to first push the RAM very hard until hearing a clicking before lowering the RAM to sit on the RAM slot. There are many posts online where people claim the RAM doesn't work just because they didn't currently insert the RAM. 2. There are different variants of the Crucial memory "FRA266". Upon receiving the RAM, you will find that the RAM has another four digitals part number printed on the tag. Mine is shown in the photo, which is C8FR. This means the RAM is built using 8x 1GB memory cells, where both sides of the RAM have memory cells. This will work on Synology. This part number can also be C8FJ, which will also work too. However, if this part number is C4FE, it means the RAM is built using 4x 2GB memory cells, where the memory cells are sodered on just one side of the RAM. In this case, it won't be compatible with Synology. Unfortunately, you will not get to see this part number until you receive the RAM. I suspect this applies to the 16GB RAM, too, as there are some people online saying it works for Synology while others saying it doesn't. Overall, I am pleased with this purchase.

The 8GB memory I purchased has been installed in my NAS server.. I had no difficulties installing the module. The NAS has accepted the memory module without issue and has been running and performing many intensive tasks to prove it is robust and safe to use in this critically demanding task. The module deserves 5 stars

One day her laptop updated to windows 11, and just like that, 4gb of ram wouldn't suffice. This was good and handy and took away a lot of anxiety

Over something getting on for 30 years of building (and occasionally breaking!) computers, a few companies have really stood the test of time when it comes to supplying top quality gear. Crucial is one of those companies and should be in anyone's (very) short list of memory suppliers. This was purchased to to expand the memory of an older Dell Vostro laptop from 8gb to 16gb. This simple upgrade has made the user of the laptop much happier and given it a new lease of life. They were convinced they needed a new laptop until I persuaded them to give this a go! Unless you are a gamer pushing the limits of your machine, a memory upgrade should be the first option if you think it is time to replace the computer. Crucial have a nifty system checker program on their website that will tell you what you need and what the system can support. Strangely you can then usually buy the same memory cheaper on Amazon! Oh and there is no great skill required to upgrade the memory in a pc/laptop. A screwdriver and a modicum of common sense will usually suffice, but in addition there are loads of videos to guide you through it.

Easy to install. NAS detected fine, no boot delays. Synology DS software now shows 10GB = Onboard 2GB and the new Crucial 8GB module.

I have a Synology DS720+ NAS, and I wanted to upgrade its memory. I have tried several memory modules before, but they did not work. Finally, I bought this memory module: "Crucial CT8G4SFRA266 8GB DDR4 2666MHz CL19". I have installed the RAM module and made a memory test using the "Synology Assistant" desktop tool, and everything is fine with no errors. So, I confirm it is working, please see the photos. PS: 8 GB additional RAM + 2 GB built-in memory = 10 GB, which is fine. Don't go after the 16 GB module unless you really require such an amount of memory.

This was a lifesaver when I got a job working from home. Laptop came with just 8GB. When performing high volume data analysis tasks that just isnt enough. This RAM was @ a great price and easy to install. It allows me to work much more quickly and efficiently , good find

Nach Google Suche und entgegen der Aussage von Synology das nur bis 6GB aufgerüstet werden kann !! ...bin ich das Wagnis eingegangen diese 8GB für meine aktuell Neue Synology DS220+ zu bestellen und bin NICHT enttäsucht worden... nach etwa 1-2 Min. nach einschalten bootete die DS wie sonst auch und erkannte die vollen nun 10GB !!! ( 2GB ab Hersteller fest verlötet ) + die neuen 8GB aus der Bestellung hier :-) Nun freue ich michund habe sofort den Zweck für den ich das gemacht habe getestet und sieh da eine VM mit Debian für den PiHole z.B. lief wirklich gut ... Windows teste ich mal aus Neugier aber das soll sicher nicht das Ziel sein :-) Fazit: - entgegen Hersteller Angabe laufen bei mir 10GB statt max. 6GB in der DS220+ - die zusätzlichen Ressourcen werden jedenfalls im Ressourcen-Monitor auch genutzt und die Auslastung entprechend Prozentual gezeigt...

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

I ordered 2x8GB ram 2666 speed, they actually worked perfectly for my old laptop so now it can handle more work. Shipping was fast 1 day delivery which is amazing.

Bought it to upgrade my ram on my gaming laptop to 16G. Been using it for a very long time and never had any issue with it. worth the purchase

O produto chegou em perfeito estado, bem embalado e com uma proteção para evitar que quebrasse durante o transporte. Demorou 10 dias para chegar. Instalei no meu notebook Dell e está funcionando perfeitamente. Até agora, só alegria, e espero que continue assim. Comprei para aumentar a capacidade de memória do meu notebook, pois sou desenvolvedor de software. Recomendo este produto, podem comprar sem medo.
