The D4RD-2666-32G is a 32 GB DDR4‐2666 MHz registered ECC (RDIMM) module, operating at 1.2 V with CL19 latency and optimized for server and workstation stability.
RDIMM (Registered DIMM) ECC (Error-Correcting Code) memory uses a register to buffer commands and corrects single-bit errors, improving data integrity and system uptime in servers and critical applications.
This module is compatible with most Intel Xeon Scalable and AMD EPYC platforms, as well as server/workstation motherboards that explicitly support DDR4 RDIMM ECC at 2666 MHz.
No. Mixing registered ECC DIMMs with unbuffered UDIMMs is not supported. Use only identical RDIMM ECC modules to ensure stability and proper system operation.
Power off the system, discharge static, align the module’s notch with the DIMM slot key, press firmly until latches click, then power on and verify ECC detection in BIOS.
Yes. For optimal performance, install matching modules in motherboard-specified slots to enable dual- or quad-channel operation as defined by your platform’s memory topology.
It operates at a standard 1.2 V supply with CL19 CAS latency for DDR4-2666, balancing power efficiency and performance in server environments.
That depends on your motherboard. Most dual-CPU server boards support up to 16 slots (8 per CPU), allowing up to 512 GB when fully populated with 32 GB DIMMs.
ECC is typically auto-detected on supported platforms. Verify in BIOS that ECC mode is enabled under memory settings to ensure error correction is active.
Use your server’s management interface or diagnostic tools (e.g., IPMI, UEFI System Utilities) to check ECC status and view corrected error logs in real time.
Increased capacity reduces paging and improves multitasking, while ECC ensures data integrity—beneficial for database, virtualization, and mission-critical workloads.
The module is backed by a limited lifetime warranty and includes technical support for installation, compatibility, and troubleshooting.
No. Registered ECC DIMMs require a server or workstation motherboard that explicitly supports RDIMM ECC. Desktop boards typically only support unbuffered UDIMMs.
Run MemTest86 or vendor diagnostics in standalone mode, verify correct seating, test modules individually, and check BIOS logs for ECC error reports.
RDIMM uses a register to buffer command/address signals, while LRDIMM adds a buffer for data lines—LRDIMMs support higher densities but draw more power and cost more.
Most modern server BIOS versions support DDR4-2666 natively. Check your motherboard vendor’s compatibility list and apply recommended BIOS updates if needed.
