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! ## Frequently Bought Together - A-Tech 8GB DDR4 2666MHz PC4-21300 (PC4-2666V) CL19 SODIMM 1.2V 260-Pin Non-ECC SO-DIMM Laptop Notebook RAM Memory Module - A-Tech 8GB DDR4 3200 MHz SODIMM PC4-25600 (PC4-3200AA) CL22 Non-ECC Laptop RAM Memory Module - SAMSUNG 870 EVO SATA SSD 500GB 2.5” Internal Solid State Drive, Upgrade PC or Laptop Memory and Storage for IT Pros, Creators, Everyday Users, MZ-77E500B/AM, Black --- ## 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.hr/products/104461157-ddr4-ram-8gb-2666mhz-pc4-21300-sodimm-laptop-memory-non](https://www.desertcart.hr/products/104461157-ddr4-ram-8gb-2666mhz-pc4-21300-sodimm-laptop-memory-non) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-24*
