SamsungM471A1K43CB1-CTD 2666MHz Memory Modules (8GB, 1 x 8GB, DDR4, 2666 MHz, 260-Pin SO-DIMM, Black, Green)

Delivered on time, product as expected, satisfied, great Amazon.

Great Service. Free Delivery and 2nd Day Delivery. I bought the Samsung 2666 Mhz 8 Gig Stick for my MSI GF63 8RD, so in case you haven't broke the factory seal on yours, it is Samsung Memory, and I was pleasantly suprized when I found this, and that it was the 2666 mhz memory, even though newegg specs said it be 2400 mhz. I haven't installed it yet. It appears to be what I ordered, as far as part number. The only difference, I can see is this stick was ' Made in the Philipines ' and the one the OEM MSI installed was ' Made in China '. Hopefully, that won't make a difference that they came off different manufacturing lines, as their the same configuration, and thats important to have two identical Ram sticks to open up the ' Dual Channels ' 2666 mhz x 2 Channels = 5.3 Gig/ Sec Ram Bandwidth on two independant 2666 mhz bandwidth streams, and now ive doubled the memory buz bandwidth, and the total DDR4 Ram size. Along with the WD Black Nvme 3.4 Gig Drive I just installed, this Rig will be Screaming Fast for 10 years to come. My Sony Viao's going on 10 years, and now its time for a new WD Blue SSD before the 10 year old one acts up. (lasted 10 years, not without maintance, I replaced the keyboard in 2015 because the K key stoped working, and installed 2 sticks of 4 Gig Ramm, to replace the 2 x 2 gigs ram, and that saved the HDD from ticking/ pagefiling, but to go anylonger without a new SSD Drive would be a fools game. OK !! I give it 5 stars on the 2nd day shipping for free, and don't expect any problems, but if I have any, ill come back to report in another thread. So, if you don't hear from me again, just know my 5.3 Gig/ Sec of Memory Bandwidth is so fast, that you wont be able to hear me ' scream ' !!

Purchased this Samsung M471A1K43CB1-CTD 8GB DDR4 2666MHz memory module back in 2020 (4 years ago and going strong), and it's been an excellent upgrade for my laptop. I paired it with an identical Samsung module to boost my system's RAM to 16GB, and the performance improvement was immediate and noticeable. The installation process was straightforward, and the module has been running smoothly without any issues. It’s been reliable for everyday tasks, multitasking, and even more demanding applications. I highly recommend this memory module for anyone looking to upgrade their system’s RAM, as it offers great value for the price and the performance boost it delivers.

Perfect exactly what I needed 🙏🏽🙏🏽🙏🏽 same as what I had already installed in my computer.. I just needed another to upgrade..

Bought this 12/19/2022 for my DS720+ and in May 2025, began to fail.Maybe I got a bad one, but for the price, buying one every 2 years is okay for me.FYI....recommend doing a memory test the moment your NAS begins to restart randomly or you cannot log into DSM even though SMB into it works. Those are the signs of a failing memory.Also, always have a backup of your data!!!!!!!! Lost all my data 4 times because of memory failing.Also, no notification from Synology that it's "unofficial". The internal RAM that comes with the DS720+ is actually Samsung, so it's best to stick with Samsung if you want an increase.With the RAM installed, the difference in performance is like night and day.Would never use a DS720+ without the extra 8gb this adds (Unless it fails and I'm waiting for Amazon to deliver the replacement lol)Let's hope this one lasts more than 2 years for me again!!

Producto de excelente calidad, todo corresponde es igual que la foto volveré a comprar nuevamente en esta tienda, le doy 5 estrellas, envío rápido y seguro la comunicación con el vendedor excelente.

While 2400Mhz memory is fairly common, 2666Mhz is still in relative infancy and difficult to find and in fact this is the first review here of the 2666Mhz speed, the rest are all for the 2400Mhz product.If you want this specific part number to exactly match an OEM installation I could only find a couple of reputable sources that sell it in the US. I had recently paid a premium for the latest generation Z2G4 workstations for my photographic studio and I wasn't going to compromise by installing anything but exactly what the manufacturer specifies which is part number M471A1K43CB1-CTD.I chose this vendor, actually a third party seller through Amazon, because they are the one and only place I could get it through Prime. I was hesitant because while they identified the correct part number they obscured the label in the product photo. I had to wonder what they were trying to hide.Not to worry, what I got was an exact match to what was preinstalled into my new workstation and the measured performance was identical. Quoting exact performance here won’t be very helpful because there are countless factors that can affect your own results compared to mine.The point I want to communicate is that if you have any doubt that this is a genuine Samsung product and this is the right place to buy it, my experience has been completely positive.
