## Description

Buy

Review: 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.
Review: 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
*by A***H on 25 January 2022*

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.
