Frequently asked questions
Are these A-Tech alternatives compatible with my Samsung server?
Yes, these modules are designed as direct replacements for the Samsung M393A4K40EB3-CWE. They share the same 32GB capacity, 3200MHz speed, and 1.2V voltage. This ensures they fit your server's 288-pin slots and maintain the registered ECC stability required for enterprise workloads without causing compatibility issues.
Can I use these RDIMM sticks in a standard desktop PC?
No, you cannot use these modules in standard desktop PCs. They are Registered DIMMs (RDIMM) intended exclusively for servers and workstations. Standard desktop motherboards typically support Unbuffered DIMMs (UDIMM), so installing an RDIMM will prevent the system from booting or recognizing the memory.
What is the difference between the Nemix and A-Tech models?
The primary difference lies in the internal model numbers and physical dimensions. A-Tech models like the ARS952 and ARS951 measure 5.25 inches in length. Nemix models, such as the ROMED8-2T, measure 5 inches long. Both brands offer 32GB capacity at 3200MHz with ECC support for your server needs.
Do all these options include error correction technology?
Yes, every option listed includes ECC support. This error correction technology detects and fixes data corruption, which is critical for server stability. All modules are DDR4 3200MHz RDIMMs, ensuring they provide the registered memory performance and reliability required for your enterprise hardware environment.
Is the Nemix kit a single stick or multiple sticks?
The Nemix offerings vary by specific model. The Nemix RAM 32GB DDR4 3200MHz ECC RDIMM is a single 32GB stick. However, the Nemix RAM 32GB 4x8GB DDR4 3200MHz ECC RDIMM is a kit containing four 8GB sticks. Check the product name to confirm if you need a single module or a full-population kit.
Will these modules work with Intel Xeon processors?
Yes, these modules are designed for enterprise environments like Xeon Scalable systems. They provide the registered memory stability required for such processors. The 32GB capacity at 3200MHz ensures efficient data handling, making them suitable for administrators managing Xeon or PowerEdge hardware that demands high reliability.
What voltage do these server memory modules operate at?
All listed modules operate at 1.2V. This is the standard voltage for DDR4 memory, ensuring energy efficiency and thermal stability. This consistent voltage rating across A-Tech and Nemix options means they will function correctly within the power specifications of your compatible server hardware.
