Product description
Crucial 16 GB DDR4-2666 SODIMM RAM extend battery life by using less power. Operating at just 1.2V compared to 1.5V for standard DDR3 memory, Crucial DDR4 SODIMMs consume 20 percent less voltage than standard DDR3 technology. Crucial DDR4 SODIMMs also contain other efficiency features, for an overall power reduction of up to 40 percent. Load applications faster and run demanding programs without lag. Crucial DDR4 SODIMMs debut at 2133 MT/s - more than 30 percent faster than DDR3 modules.

Make everything on your computer fasterMemory is a component in your computer that allows for short-term data access. Since your system's moment-to-moment operations rely on short-term data access — loading applications, browsing the Web or editing a spreadsheet — the speed and amount of memory in your system plays a critical role. Load apps in seconds by increasing the speed of your memory and installing more of it. |
Multitask with easeIf you're like us, you use your computer to do lots of things at once. You might be editing a document, while also looking at pictures and browsing the internet. This naturally leads to a performance problem: every app you're running requires memory and competes for a limited pool of resources. Overcome this by installing high-density modules in each memory slot for seamless multitasking. |
Extend battery lifeOne of the most important aspects of laptop performance is battery life. By upgrading your memory, you can potentially take advantage of lower voltage modules — and increase energy efficiency by up to 40% when using the latest memory technology.* What's more, by simply installing more memory, you'll reduce the number of times your system has to access the hard drive (paging). Less paging means tasks are done faster — using less battery power. *DDR4 modules only |

Install with ease — no computer skills requiredWith just a screwdriver, your owner's manual, and a few minutes of time, you can install memory — no computer skills necessary. Just watch one of our three minute install videos, and we'll walk you step-by-step through the process. Don't pay a computer shop to do something you can do in minutes. |
Maximize the value of your systemAt a fraction of the cost of a new system, a memory upgrade is one of the most affordable ways to increase performance. Get more out of your laptop by giving it the resources it needs to perform. |

No issues this many months on. When it comes to RAM, usually they're either DOA or will last many many years. I don't think I've personally ever had one fail on me over time.
I recently added an eGPU to my setup and that combined with the i7 and these two ram sticks, this machine is a beast!
They arrived quickly, and if you're planning to use them in your Mac mini, I highly suggest that you also purchase the iFixit 64 bit driver set so you can get into your machine to do the work.
Note the amazon description part number is in error - shows CT2K16G48FD8266 should be CT2K16G4SFD8266 as per Crucial. Works fine in Mac mini 2018, fitted in 40minutes, way cheaper than via Apple.

It's a well known brand. There is slightly cheaper out there but I suspect this product is the right choice compatibility wise as you see lots of compatibility Issus on many other similar products claiming same compatibility for my machine.
Bought from Amazon USA because here in Australia it is much more expensive.
Crucial customer service was great at answering Questions prior to purchase. Happy!

Da ich hauptsächlich Video- und Bildbearbeitung mache,
war mir beim Neukauf nach einer Weile mit 8 GB doch relativ wenig.
Daher habe ich mir beim Black Friday diesen Riegel von [ Crucial CT2K16G4SFD8266 32GB (16GB x2) Speicher Kit (DDR4, 2666 MT/s, PC4-21300, Dual Rank x8, SODIMM, 260-Pin) ] für schlappe 95 EURO geholt [Nov. 28.2019].
Die Lieferung kam eher an als gedacht, passte um so besser.
Ich hätte es mir von Amazon gewünscht, dass die Verpackung gepolstert wäre.
Wie man die ins iMac rein tut ist sicherlich sehr einfach, auch Laien sind der Lage dies zu bewältigen.
INFO: Die Garantie bleibt dann auch WEITERHIN bestehen, auch wenn ihr aufrüstet.
1. iMac vom Strom trennen
2. Vorsichtig den iMac sein Bildschirm auf einer Decke lecken
3. Schraubenzieher (flachen Kopf) bereit stellen
4. TIPP: Um Kratzer zu vermeiden, könnt ihr ein Taschentuch vor der Öffnung des Metall Knopf tun
5. Nun vorsichtig rein
6. Alles anschließen > anmachen
Ü B R I G E N S:
der RAMspeicher wird bei jedem Neustart einem Check unterzogen.
Bei Windows ist gibt da sicherlich viele Programme, eines der bekanntesten davon ist: MemTest
ARBEITSSPEICHER LEEREN:
Wenn euer Mac langsam ist, kann das Leeren des Arbeitsspeichers helfen,
wie das geht ist total einfach nutzt dazu bitte KEINE Applikationen vom MacStore!
Das könnt ihr schneller und besser!
K U R Z A N L E I T U N G:
1. Öffnet über die Spotlight-Suche oder CMD+LEERTASTE die Aktivitätsanzeige.
2 Klickt dort auf den Reiter "Speicher". Hier wird euch nun der momentan belegte Speicher angezeigt.
3. Lasst das Fenster mit der Aktivitätsanzeige geöffnet und starten nun über die Spotlight-Suche das Terminal.
4. Gebt dort den Befehl sudo purge ein und bestätigen das mit [Enter].
5. Daraufhin werdet ihr aufgefordert, Euer Admin-Passwort einzugeben.
Bestätigt das anschließend ebenfalls mit [Enter].
6. Zurück in der Aktivitätsanzeige solltet Ihr nun sehen, dass weniger Speicher belegt ist.
Ich bin echt sehr froh, dass dies alles geklappt hat und das ich mit dem Kauf
ein Schnäppchen gemacht habe.
Bedanke mich für das durchlesen meiner Rezension!
Hoffe es war eine Hilfe bei der Kaufentscheidung!

In other words just make sure that both ram stick you have do have the same frequency, size and supported CL and off course the same gen (DDR4 here). They will work well in dual channel. You dont need to but the same ram as stock or a new ram kit (which is often the more expensive option) to make your pc (desktop or laptop) run in dual channel mode, the chances of this not happening are negligible these days even on my amd cpu.
Plus this thing was delivered to me in less that 72 hours of order in a perfect condition with excellent packaging.

This RAM was well pack and upgrading is a 'under 5 min' job.
New Geekbench score post upgrade (40Gb in total) is 5438 / 22675 (2.4% single-core gain and 10% multi-core gain).
So far, everything seems stable.
