Crucial 4GB Single DDR3 1866 MT s PC3-14900 SODIMM 204-Pin Memory - CT51264BF186DJ 4GB

Funciona correctamente, no da problemas el sistema esta estable y el precio fue acorde al tipo de memoria.

Ho utilizzato questo prodotto per upgradare la memoria del mio NAS da 4 a 8Gb. Consegna Amazon Prime velocissima e prodotto installato rapidamente e senza problemi. Questo modello di RAM è assolutamente compatibile con il mio NAS Synology DS918+. Performa come quella già installata di default ma costa moooolto meno!

Esta memoria de 4GB de portátil es perfecta para ampliar la memoria de 4GB de un NAS ds918+ a los máximos 8GB que soporta (oficialmente).Para instalarla, basta con apagar y desenchufar tu NAS, retirar los discos, y colocarla con cuidado en la ranura libre que queda a la vista en un panel lateral del interior de la caja. Una vez instalada, hay que volver a colocar los discos y conectar el NAS de nuevo. Puede que tarde un poco más de lo normal en iniciarse la primera vez, la placa tiene que detectar la memoria.Hay que asegurarse de que está bien instalada, con ambas pestañitas apretadas. Si al encender tu dispositivo, el panel de gestión de recursos muestra 4GB (como me pasó a mi), simplemente apaga el dispositivo, desenchúfalo, respira hondo, retira la memoria con mucho cuidado y vuelve a empezar.El proceso es similar a otros aparatos de Synology, hay tutoriales en YouTube.Salvo el sustito de la primera instalación, funciona a la perfección, 10/10.

NOTE: I already upgraded my CPU from the stock i3 to an i5 processor*, so my computer is now about as upgraded as it can be. Upgrading a CPU is possible with this model laptop as the CPU isn't soldered to the Mother Board. The reason I upped the ram is I was running out of ram regularly with heavy video editing projects (originally had 8GB of ram).I use Ubuntu Linux (16.04 64bit) and do not know how this ram would function on this computer if it were running Windows as I do not use Windows (and very happy that I don't)... although, I would guess that this ram would work fine.This is a very easy upgrade for most laptops... just check your specific model on the Crucial website to be sure you are ordering the correct ram modules for your specific model computer to avoid the hassle of getting incompatible ram modules ;)So far I have had no problems with these ram units, and everything worked perfectly when I booted up after installing them! I am using them in a Toshiba Satellite c855-s5355 Laptop running Ubuntu 16.04 and my System Monitor shows 15.6 GB of usable RAM out of the 16 GB installed (8GBx2)... I am a happy camper!*fyi... I installed the Intel Core i5-2410M CPU @ 2.30GHz (2 cores/4 threads) which worked perfectly in my computer. However, I do not know if Windows 8 or 10 would have hiccuped with this upgrade... again, I use Linux, so it just worked in my case :)

Bought this to expand the 4 GB standard RAM in the Synology DS918+ server to 8 GB.Recommendations from a number of sites led me to this part. I was uncomfortable about accidentally damaging my excellent server but the £23 was too good to disregard. I'm very glad I did. It's been in for a week now and has been running fine.After the 10-min DIMM installation, I used the Synology Assistant on Windows to command the DS918+ to run its RAM test. That took 3-odd hours but came through clean. That's time well spent to get that reassurance.I can now run a virtual Ubuntu Linux using 4 GB comfortably alongside the server's native DSM using the other 4 GB. All feels solid and nimble. Great upgrade, good price.
