Rest in peace, crucial
Ram worked perfectly. Shame that it's impossible to find now.

Great piece of kit
I brought this RAM one stick 16GB at 2666MHZ on the 1 of January 2021. I used it in conjuction with a single 8GB RAM already installed on my Gaming laptop. Nearly two years later and still going strong. I still get 60+FPS on games even though I use two different types of RAM sizes. Gaming performance never suffered. Its a plug and play type of kit, just install it into the memory banks and you're good to go. It came in anti static packaging so no need to worry about that like other sellers. Just ensure that you get that right type for your PC DDR4 and speed 2666MHZ. If your current ram is slower like 2400MHZ then your PC will automatically downclock the RAM to 2400MHZ or to whatever the slowest speed of your RAM is. So it is vital that your get the right type and right speed for your PC for value for money. Hope this helps.

Works on iMac Retina 5K 27-inch - 2020
I upgraded from 8GB to 32GB (2x16GB). This wasn't the official recommended upgrade kit for the iMac Retina 5K 27-inch - 2020. However the spec was exactly the same and the price was much cheaper. Therefore, I decided to give it a go and I am really pleased I did. I watched a video on YouTube and it took less than 5 minutes to fit. The iMac has a little container on the back with a door that you release using a button under the power lead. Press the button, pop the old memory modules out, pop the new ones in - job done. I'm so please I upgraded.

The best thing you can do for a computer from one of the best suppliers in the business.
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.

Its a RAM Stick
I doubt you have the exact same motherboard as me, but this specific ram is great and it does what ram does it gave me extra ram storage and my pc ran more smoothly after. Of course it was very expensive for £50+ but If your desperate. Go for it

It can work with Synology
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.

Amazing Value but prefomance is what you payed for
I got it for under twenty five pounds , it was for a laptop upgrade , a laptop that came with only 4GB Stick , now it has 12GB . The CL19 latency at this speed is not amazing , I run a kit at home that runs at 3600MHz with CL16 . Over all , fantastic cheap upgrade for a cheap laptop :) , will not break the bank.

It's a memory card
I managed to install with ease and now have them working perfectly well in my laptop, they arrived in one piece and in good time. And can't fault the seller, after a bit of a disaster with DPD refusing to deliver without a pin and returning to the seller, the seller immediately stepped in and got another sent out with a different delivery company. Very happy with the service and the memory cards

Comprei um memória de 16GB para expandir a memória total do meu laptop pra 24GB. Fiz uma pesquisa extensa antes para saber quais as melhores marcas de memória RAM, e a Crucial foi uma das principais recomendações. Tem três semanas que meu laptop está rodando com a memória nova, e consigo usar máquina virtual, rodar programas da Adobe e jogar jogos tranquilamente. Super recomendo! A instalação no slot foi bem simples de fazer, porém encontrei um problema com o Windows, que se recusava a incializar após eu inserir a memória nova. Fui descobrir que era uma reclamação de paridade do próprio Windows mesmo, pois os slots de RAM do meu laptop estavam com 16 x 8, e o recomendado é sempre ser duas memórias de capacidades iguals, 8x8, 16x16, etc. Após configurar o Windows para aceitar a configuração 16x8, ele inicializou normalmente, e desde então, não tive mais problemas.

Bought as an upgrade for my laptop MSI GL75 9SDK Started working right after installation without any tuning. CPU-Z shows full match to the described characteristics. Dual-channel mode just works. The system looks to be pretty stable and fast. Wrt performance it's probably better to buy a smaller volume bars which may come with smaller timings, but 19 is already pretty good IMO. I any case I've bought this pack to have enough volume but not enough speed, and I've got exactly what was expecting. Maybe except the price which taking account the shipment and import clearance taxes turned out to be higher than from local retailers (overall local Belarus prices are 14% cheaper for the same memory) If anyone curious there is dmidecode below: Array Handle: 0x003A Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 32 GB Form Factor: SODIMM Set: None Locator: ChannelB-DIMM0 Bank Locator: BANK 2 Type: DDR4 Type Detail: Synchronous Speed: 2667 MT/s Manufacturer: Micron Serial Number: 2F3A12AE Asset Tag: 9876543210 Part Number: 16ATF4G64HZ-2G6B4 Rank: 2 Configured Memory Speed: 2667 MT/s Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V Memory Technology: DRAM Memory Operating Mode Capability: Volatile memory Firmware Version: Not Specified Module Manufacturer ID: Bank 1, Hex 0x2C Module Product ID: Unknown Memory Subsystem Controller Manufacturer ID: Unknown Memory Subsystem Controller Product ID: Unknown Non-Volatile Size: None Volatile Size: 32767 MB Cache Size: None Logical Size: None

Purchased to upgrade an older (5 years) Laptop that has an upper RAM limit of 16gb, came with 8. Recognized immediately. Ran a few memtest's including Memtest86+, everything was good, no errors. Matched expected capacity, speed etc. Well oackaged, standard plastic holders. No problems, buy with confidence.

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!
