I bought these to replace some failing RAM and figured I would add ECC support since my CPU and mobo support it. I have a Ryzen 3800X with the Asrock x470 Gaming ITX/ac. These sticks work perfectly fine at 3200MHz, but I did have to clear my CMOS to get my machine to POST. I tested them fully with memtest86+ v7.0 without any issues. Highly recommend! Review: Good price, fit, and works on HPE Proliant Gen 10 Plus v2 - A-Tech price is good and this (2x32GB 2R8 UDIMM) one is compatible with my HPE Proliant Gen 10 Plus v2 desktop server (2 DIMM slots, max out at 64GB). It would have been better if A-Tech lists the exact part number on its website's compatibility list so that matching it to desertcart would be easier. The upgrade takes minutes. ## Features - A-Tech RAM Memory compatible for select DDR4 Server and Workstation systems only; (*WILL NOT WORK with Desktop or Laptop Computers/PCs*) - 128GB RAM Kit (4 x 32GB Modules); DDR4 DIMM 288 Pin; Speeds up to 3200MHz PC4-25600 (PC4-3200AA) - ECC Unbuffered UDIMM; 2Rx8 - Dual Rank x8; JEDEC DDR4 standard 1.2V - Improves system performance, workload capacity, and reduces bottlenecks by increasing memory (RAM) resources - Note: This memory is ECC Unbuffered and cannot be mixed with different ECC types such as ECC Registered, ECC Load Reduced, or Non-ECC Unbuffered; (Memory compatibility can vary among different system models and their installed components; please verify compatibility and follow memory channel guidelines to ensure maximum performance) - Each A-Tech memory module is built and tested for superior performance and trusted reliability - All A-Tech products are covered with a Limited Lifetime Warranty and are backed by our top rated support team to help guide you every step of the way ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BQ9NGSSN | | Additional Features | ECC Unbuffered, Ecc | | Best Sellers Rank | #246 in Computer Memory | | Brand | A-Tech | | Column Address Strobe Latency | CL22 | | Compatible Devices | Server, Workstation | | Computer Memory Size | 128 GB | | Customer Reviews | 4.3 out of 5 stars 17 Reviews | | Data Transfer Rate | 25600 megabytes_per_second | | Form Factor | DIMM | | Item Type Name | Computer RAM Memory | | Manufacturer | A-Tech | | Memory Form Factor | UDIMM | | Memory Generation | DDR4 | | Memory Speed | 3200 MHz | | Mfr Part Number | AT32G4D4D3200ED8N12V | | Model Name | A-Tech Enterprise Series | | Model Number | AT32G4D4D3200ED8N12V | | Number of Pins | 288 | | RAM Memory Technology | DDR4 | | RAM Size | 128 GB | | Special Feature | ECC Unbuffered, Ecc | | Unit Count | 4 Count | | Voltage | 1.2 volts | | Warranty Description | Limited Lifetime Warranty covering defects in materials and workmanship | ## Product Details - **Brand:** A-Tech - **Compatible Devices:** Server, Workstation - **Computer Memory Size:** 128 GB - **Memory Speed:** 3200 MHz - **RAM Memory Technology:** DDR4 ## Images ![A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - Image 1](https://m.media-amazon.com/images/I/91HH3HPk3jL.jpg) ![A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - Image 2](https://m.media-amazon.com/images/I/8171ISP5T8L.jpg) ![A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - Image 3](https://m.media-amazon.com/images/I/71pFjaNkTyL.jpg) ![A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - Image 4](https://m.media-amazon.com/images/I/81gxteRAWNL.jpg) ![A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - Image 5](https://m.media-amazon.com/images/I/81rt+1ZeX3L.jpg) ## Available Options This product comes in different **Color, 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. 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! **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. Each memory type uses different slot designs, voltages, and architectures, so your system must support the memory type specifically. **Q: Can I mix ECC Unbuffered (ECC UDIMM) modules with other ECC types?** A: 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. **Q: What ECC type does my system need and which slots should I use?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Rock solid *by W***Y on March 12, 2024* The modules I received were black instead of green like the picture showed, but this is better for me anyways.

Update: NOTICE: READ SECOND UPDATE!!! Purchased a single stick to replace the damaged stick; did not resolve the issue. Returned the stick of memory. Seller claims I never returned the item. They scammed me out of both the warranty and the price of a stick. Secondary update: I messaged the seller, and they say they received the item and did not make any claim against my refund. I am currently contacting Amazon in regards to this discrepancy. ## Frequently Bought Together - A-Tech Server 128GB Kit (4x32GB) DDR4 3200MHz PC4-25600 ECC UDIMM 2Rx8 Dual Rank 1.2V ECC Unbuffered DIMM 288-Pin Server & Workstation RAM Memory Upgrade Modules (A-Tech Enterprise Series) - QNAP TVS-h1288X-W1250-16G High-speed media NAS with Intel® Xeon® W-1250 CPU and Two 10GbE Ports --- ## 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/517415352-a-tech-server-128gb-kit-4x32gb-ddr4-3200mhz-pc4-25600](https://www.desertcart.jp/products/517415352-a-tech-server-128gb-kit-4x32gb-ddr4-3200mhz-pc4-25600) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-13*
