But running in single channel will clock it to 1066MHZ like DDR3L! I wouldn’t put this stick of DDR4 ram in a DDR3 machine! It might not post on the first boot or it might not boot at all! **Q: I have m471a1g43db0 -cbp in one slot. will this be compaitible with it in 2nd slot to expand to total 16 gb** A: It should, your old memory is slower speed **Q: Will this work with acer Acer Aspire 5 ?** A: Are you swapping out a single module, or adding RAM to your machine? If adding RAM, you really should pair the exact same type of module with it, (DDR rating, speed/bandwidth, latency, etc), just open your laptop up and look at the sticker on the module itself. If you are replacing a single module to be used on its own, then yes this RAM should work in the Acer aspire 5, it uses DDR4 and the 260-pin sodimm form factor. **Q: Does it wortks on lenovo 81w10094us laptop?** A: if you have available DDR4 260pin DDR4 memory module, then yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent *by B***N on 1 October 2024* Perfectly fits and works in HP laptop ### ⭐⭐⭐⭐⭐ Works with Synology *by S***N on 31 July 2024* Works well with Synology DS220+. Total 10GB. ### ⭐⭐⭐⭐⭐ Working Perfectly in my DS224+...finally. *by D***E on 6 February 2025* Installed this in my DS224+ and booted the NAS. I checked the resource monitor and I still had only 2gb of memory. I figured I received a DOA memory stick that I would have to send back. Then I remembered reading somewhere that another person had the same issue and it turned out that the memory stick wasn't seated properly. I shut down the NAS, opened it up, and removed the memory stick. Then I reinstalled it and made sure I pressed down with more force than the first time. I felt a little snap so I hoped the memory stick was seated properly now. Re-assembled the NAS and booted it up. I checked the resource monitor and tada... now it shows 10gb of memory. Has been working perfectly for a week now. So, if you think you received a bad memory stick, try removing it and re-installing it like I did. ## Frequently Bought Together - Samsung M471A1K43CB1-CTD 8GB DDR4 PC4-21300, 2666MHZ, 260 PIN SODIMM, 1.2V, CL 19 laptop ram memory module - Samsung 870 EVO SATA III SSD 1TB 2.5” Internal Solid State Drive, Upgrade PC or Laptop Memory and Storage for IT Pros, Creators, Everyday Users, MZ-77E1T0B/AM --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/257469016-m471a1k43cb1-ctd-8gb-ddr4-pc4-21300-2666mhz-260-pin-sodimm](https://www.desertcart.us/products/257469016-m471a1k43cb1-ctd-8gb-ddr4-pc4-21300-2666mhz-260-pin-sodimm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-10*
