No, most desktop PCs do not support ECC memory and instead require Non-ECC memory. This memory is designed for workstations and servers compatible with DDR4 ECC Unbuffered memory. If you’re unsure, contact our support team, we’re happy to help! What’s the difference between DDR4 and other types of memory and can I use them interchangeably? 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. Can I mix ECC Unbuffered (ECC UDIMM) modules with other ECC types? No, you cannot mix ECC Unbuffered with ECC Registered (RDIMM), Load-Reduced (LRDIMM), or Non-ECC Unbuffered (Non-ECC UDIMM) modules. All installed memory modules must be the same ECC type or your system will fail to boot. What ECC type does my system need and which slots should I use? Refer to your system or motherboard manual for supported ECC types and correct memory channel configuration. Using the wrong type or incorrect slot population can cause boot failures or reduce system stability. DDR4 ECC Unbuffered DDR4 ECC Registered DDR4 ECC Load Reduced DDR4 ECC Unbuffered 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 - Memory RAM Replacement for Synology D4EC-2400-16G ## Technical Specifications | Specification | Value | |---------------|-------| | Additional Features | Lightweight | | Asin | B07RGM9T4L | | Best Sellers Rank | #458 in Computer Memory | | Brand | A-Tech | | Column Address Strobe Latency | 17 | | Compatible Devices | SA3200D, UC3200, RS1619xs+, RS3618xs, RS2818RP+, RS2418RP+, RS2418+, RS4017xs+, RS3617xs+, RS3617RPxs | | Customer Reviews | 5.0 5.0 out of 5 stars (1) 5.0 out of 5 stars | | Data Transfer Rate | 19200 megabytes_per_second | | Form Factor | DIMM | | Item Weight | 0.27 g | | Manufacturer | A-Tech | | Memory Form Factor | UDIMM | | Memory Generation | DDR4 | | Memory Speed | 2400 MHz | | Mfr Part Number | D4EC-2400-16G-ATCRS | | Model Number | D4EC-2400-16G-ATCRS | | 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 - **Memory Speed:** 2400 MHz - **RAM Memory Technology:** DDR4 ## Images ![A-Tech 16GB RAM Replacement for Synology D4EC-2400-16G | DDR4 2400 MHz PC4-19200 ECC UDIMM Unbuffered DIMM Memory Compatible for NAS & SAN Servers - Image 1](https://m.media-amazon.com/images/I/71G-mQl59JL.jpg) ![A-Tech 16GB RAM Replacement for Synology D4EC-2400-16G | DDR4 2400 MHz PC4-19200 ECC UDIMM Unbuffered DIMM Memory Compatible for NAS & SAN Servers - Image 2](https://m.media-amazon.com/images/I/715hi3fs66L.jpg) ![A-Tech 16GB RAM Replacement for Synology D4EC-2400-16G | DDR4 2400 MHz PC4-19200 ECC UDIMM Unbuffered DIMM Memory Compatible for NAS & SAN Servers - Image 3](https://m.media-amazon.com/images/I/61n2XLqhoNL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Will this work in my desktop computer?** A: No, most desktop PCs do not support ECC memory and instead require Non-ECC memory.
