No, DDR4 memory is not compatible or interchangeable with other types such as DDR5, DDR3, and so on. Each memory type uses different slot designs, voltages, and architectures, so your system must support the memory type specifically. What’s the difference between DIMM and SO-DIMM memory? 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. What does "Non-ECC" mean and do I need "ECC" memory instead? 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. How do I know which speed to choose? 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 Is this compatible with my system or computer? 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! is a leading brand of Computer Memory (RAM) based in the . We offer a vast variety of memory products to solve all your memory needs; from servers to desktop PCs to laptops and more! All A-Tech products are rigorously tested to ensure high quality, dependable performance. Upgrade your system with confidence with . Memory (RAM) gives applications a place to temporarily store data which allows your computer to quickly access information. Using multiple programs/applications at once or doing resource intensive activities (such as video/photo editing, gaming, programming and more) can slow down your system as each compete for a limited amount of memory resource. A RAM upgrade can improve performance by expanding your system's memory capacity allowing your computer to take on more while maintaining a fast and smooth experience. There are many types of RAM including RD, SD, DDR, DDR2, DDR3, DDR4, and DDR5, with DDR5 being the newest version. All system’s have their own memory requirements and will only support one of those specific types of RAM. For instance, a laptop that requires DDR4 RAM can only support DDR4 RAM. Each type of RAM has different pin sizes and notch locations meaning a DDR3 RAM module will only fit into a DDR3 RAM slot and so on. Refer to your system’s manual to determine the supported RAM specifications Along with RAM types, there are also different Form Factors or physical sizes of RAM. SODIMM (or SO-DIMM) RAM is used in laptops and notebooks and is also commonly used in select All-in-One (AIO) computers, Mini PCs and NAS systems. DIMM RAM is used in Desktops Computers as well as Workstations and Servers. The two sizes are not interchangeable; a DIMM module will not fit into a system that requires SODIMM RAM and a SODIMM module will not fit into a system that requires DIMM RAM. Non-ECC Unbuffered (or simply Non-ECC): Primarily used in Desktop PCs, Laptops, All-in-One (AIO) computers, & Mini PCs as almost all those system types only support Non-ECC Unbuffered memory ECC Registered: Only used in Servers and select Workstations ECC Load Reduced: Only used in Servers and select Workstations ECC Unbuffered: Only used in Servers and Workstations ECC Fully Buffered: Only used in select Servers that support DDR2 RAM Different ECC types cannot be mixed within the same system, only one type can be used. ## Features - Compatible with select DDR4 Desktop computers + Easy to install at home, no expertise required - Maximize your system's performance, boost loading speeds and multitask with ease - Backed by A-Tech's Lifetime Warranty + Friendly tech support team available to help before and after your purchase - Single 16GB RAM Module | DDR4 DIMM 288-Pin | Speeds up to 2133MHz, PC4-17000 / PC4-2133P - NON-ECC Unbuffered | 2Rx8 - Dual Rank | JEDEC DDR4 standard 1.2V ## Technical Specifications | Specification | Value | |---------------|-------| | Additional Features | Lightweight | | Asin | B07KGMBNQH | | Best Sellers Rank | #136 in Computer Memory | | Brand | A-Tech | | Column Address Strobe Latency | 15 | | Compatible Devices | Desktop, Workstation | | Customer Reviews | 4.6 4.6 out of 5 stars (102) 4.6 out of 5 stars | | Data Transfer Rate | 17000 megabytes_per_second | | Form Factor | DIMM | | Manufacturer | A-Tech Components | | Memory Form Factor | UDIMM | | Memory Generation | DDR4 | | Memory Speed | 2133 MHz | | Mfr Part Number | AT16G1D4D2133ND8N12V | | Model Name | A-Tech | | Model Number | AT16G1D4D2133ND8N12V | | Number Of Items | 1 | | Number Of Pins | 288 | | Ram Memory Technology | DDR4 | | Ram Size | 16 GB | | Voltage | 1.2 volts | | Warranty Description | Limited Lifetime Warranty Covering Defects In Materials And Workmanship | ## Product Details - **Brand:** A-Tech - **Computer Memory Size:** 16 GB - **RAM Memory Technology:** DDR4 - **Memory Speed:** 2133 MHz - **Compatible Devices:** Desktop, Workstation ## Images ![A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - Image 1](https://m.media-amazon.com/images/I/71grh+jrFoL.jpg) ![A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - Image 2](https://m.media-amazon.com/images/I/71VwDcT0BuL.jpg) ![A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - Image 3](https://m.media-amazon.com/images/I/81jc+5QAp8L.jpg) ![A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - Image 4](https://m.media-amazon.com/images/I/71m6AXi83TL.jpg) ![A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - Image 5](https://m.media-amazon.com/images/I/719bXSLemVL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What’s the difference between DDR4 and other types of memory and can I use them interchangeably?** A: No, DDR4 memory is not compatible or interchangeable with other types such as DDR5, DDR3, and so on.

The gskill ram is fine , Ive used it with a smaller capacity Kingston stick without issues.. After playing witht he bios the atech ram woked when I booted the computer but if I did a restart it would hang...So i dunno if it s bios setting or a bad stick or its just not compatable with my gskill stick... I am unable to get the two sticks to work together reliably without getting hung on restarts.. I dunno if buying another 16gb or atech and pairing them both would work.I give the ram 5 stars cause I am not sure whos fault it is that its not working.. lol.. good ram for the price. ## Frequently Bought Together - A-Tech 16GB DDR4 2133 MHz UDIMM PC4-17000 (PC4-2133P) CL15 DIMM 2Rx8 Non-ECC Desktop RAM Memory Module - A-Tech 16GB DDR4 2666 MHz UDIMM PC4-21300 (PC4-2666V) CL19 DIMM Non-ECC Desktop RAM Memory Module --- ## 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.jp/products/188398482-a-tech-16gb-ddr4-2133-mhz-udimm-pc4-17000-pc4](https://www.desertcart.jp/products/188398482-a-tech-16gb-ddr4-2133-mhz-udimm-pc4-17000-pc4) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-14*
