Crucial RAM CT8G4SFRA266 8GB DDR4 2666MHz CL19 Laptop Memory

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.

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.

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.

Ram worked perfectly. Shame that it's impossible to find now.

let's start with the negative. the packaging from crucial has got cheaper and cheaper - but this is also reflected in the price as that has got cheaper, but i wouldn't mind something a little more than a flimsy little plastic box. but now the good - plug it in, boot up and away i go. no messing around in the bios, no issues, it just worked. what more could you ask for!

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.

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.

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
