Review: Manufactured +3yrs ago? - Memtest86 said it passed all of the tests. What I found interesting, is that MemTest86 identified this 4GB memory stick as being "Kingston" brand and being manufactured on the 10th week of 2022, despite me purchasing it in Jan 2026... Seems to be working fine in my NUC, though. ## Features - A-Tech 4GB RAM Module, DDR4 SO-DIMM 260-Pin, 2666MHz / 2667MHz PC4-21300 (PC4-2666V) - Non-ECC Unbuffered, JEDEC DDR4 Standard 1.2V Operating Voltage - Compatible with select DDR4 SODIMM capable Laptop, Notebook, Mini PC, and All-in-One (AIO) computer systems.

Each memory type uses different slot designs, voltages, and architectures, so your system must support the memory type specifically. **Q: What’s the difference between DIMM and SO-DIMM memory?** A: DIMM and SO-DIMM represent two different physical sizes of memory. DIMM is the larger type used in standard desktop computers. SO-DIMM is the smaller type used in laptops, mini PCs, and compact systems. They are not interchangeable. **Q: What does "Non-ECC" mean and do I need "ECC" memory instead?** A: Non-ECC (non-error correcting) memory is required for most laptops and desktops. ECC is typically only used in servers or workstations and is not interchangeable with Non-ECC memory. If your system doesn’t mention ECC support, you need Non-ECC. **Q: How do I know which speed to choose?** A: Each system has its own max supported speed. If the memory is faster than your system allows, it will automatically downclock to that max speed, meaning it's safe to buy faster memory. To confirm the max supported speed, refer to your system's manual **Q: Is this compatible with my system or computer?** A: Refer to your system's manual to confirm the supported memory type, capacity, form factor, and ECC support. If you're unsure, contact our support team, we're happy to help you find the exact memory your system needs! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Upgrade or Replacement *by C***T on November 8, 2025* Great replacement for a bad SODIMM or a memory upgrade for your laptop.

Insert thoroughly! *by A***Y on January 10, 2022* I upgraded RAM in a number of laptops before so I am not new to this RAM slots. But with Synology I had to reinsert it after first attempt - at first Synology just did not see it. This is more about slot in Synology I think. The module is a steal in comparison with original ones price. ## Frequently Bought Together - A-Tech 4GB DDR4 2666MHz PC4-21300 (PC4-2666V) CL19 SODIMM 1.2V 260-Pin Non-ECC SO-DIMM Laptop Notebook RAM Memory Module - Synology 2-Bay DiskStation DS224+ (Diskless) - Seagate IronWolf 8TB NAS Internal Hard Drive HDD – 3.5 Inch SATA 6Gb/s 7200 RPM 256MB Cache for RAID Network Attached Storage – Frustration Free Packaging (ST8000VNZ04/N004) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/178310998-a-tech-ddr4-ram-4gb-2666mhz-pc4-21300-sodimm-laptop](https://www.desertcart.sn/products/178310998-a-tech-ddr4-ram-4gb-2666mhz-pc4-21300-sodimm-laptop) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-07*
