This 32GB DDR5-4800 UDIMM with ECC is purpose-built for professional workstations and entry-level server platforms that demand data integrity, where its unbuffered signal topology and dual-rank x8 organization improve memory interleaving for consistently high throughput under mixed workloads. The aggressive CL4 column access latency dramatically reduces first-word access delays, making it especially effective for latency-sensitive applications like electronic design automation and financial modeling.
1. Error-correcting code memory reliably detects and corrects single-bit errors, preserving long-term data integrity for always-on enterprise applications and preventing costly silent data corruption in database transactions.
2. A 32GB module capacity raises virtualization density substantially, allowing more active VMs per physical host and reducing the need for disruptive hardware upgrades.
3. DDR5-4800 bandwidth accelerates concurrent request handling, cutting latency for high-throughput web services and in-memory caching layers under peak traffic.
4. Dual Rank x8 organization ensures memory interleaving keeps data paths busy, delivering sustained throughput when running large-scale analytics or containerized microservices.
5. A 1.1V operating voltage lowers overall server power consumption and cooling requirements, directly improving total cost of ownership in sprawling data center environments.
Built for workstations and entry-level servers, the Samsung M324R4GA3BB0-CQKOD is a 32GB DDR5-4800 ECC UDIMM that quietly solves two problems most IT professionals fear: silent data corruption and performance unpredictability under sustained load.
When running a virtualization cluster with multiple VMs sharing physical memory, a single bit flip in a critical lookup table can cascade into corrupted databases or even complete node crashes. The module's end-to-end ECC detects and corrects single-bit errors on the fly, transforming an invisible risk into a non-event. That means your hypervisor and guest VMs keep running cleanly, even as memory density scales.
In latency-sensitive in-memory databases like Redis or SAP HANA, the combination of unbuffered signaling and a genuine CL40 low-latency profile cuts access time noticeably compared to registered alternatives. Paired with dual-rank x8 organization that interleaves two 16Gb banks for higher sustained bandwidth, large query sets load faster without stalling the pipeline. Meanwhile, the native 1.1V supply respects power budgets in dense deployment racks, lowering thermal overhead so your cooling dollars go further. This is memory engineered to let reliability and responsiveness coexist, not compromise.
General Virtualization
For DDR5 ECC UDIMMs, equip the host with at least four identical 32 GB modules to populate all memory channels and enable symmetric multi-channel access. This configuration delivers reliable, error-corrected capacity for dozens of moderate VMs while keeping infrastructure costs predictable. Avoid mixing DIMM ranks or speeds to preserve memory interleaving performance under hypervisor pressure.
In-Memory Database
Maximize total capacity by deploying eight 32 GB dual-rank UDIMMs (256 GB) across both memory controllers, ensuring low latency for real-time analytics. The CL4 timing and ECC protection guard against bit flips during high-throughput cache operations. Match these modules exactly to eliminate training mismatches and sustain deterministic response times.
High-Performance Computing
Populate all available UDIMM slots with identical 32 GB DIMMs to achieve balanced bandwidth, which is critical for MPI workloads. Dual-rank x8 construction boosts bank-level parallelism, while 4800 MT/s speed feeds modern vector engines. Use matched kits and validate system stability under sustained load to prevent silent data corruption in long-running simulations.
Rigorously tested server memory. Compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen11, Lenovo ThinkSystem SR650 V3.
Q: Can I mix this M324R4GA3BB0-CQKOD with other memory modules of different brands or speeds?
A: Mixing is not recommended in server environments. Different brands, speeds, or ranks may cause instability. To ensure ECC protection and signal integrity, use identical modules with the same part number across all channels.
Q: Is this memory compatible with my system?
A: This DDR5 ECC UDIMM targets servers and workstations using Intel Xeon W-2400/3400 or AMD Ryzen 7000/EPYC 4004 platforms with W680 or equivalent chipsets. Verify that your board supports unbuffered ECC and 288-pin DDR5.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate one DIMM per channel in the primary slot (e.g., DIMMA1) for single-rank configurations. For this dual-rank module, fill one per channel first to maintain balanced memory interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade ECC UDIMM, it adheres strictly to JEDEC DDR5-4800 standard timings. Overclocking or XMP is not supported to preserve data integrity and long-term reliability in mission-critical workloads.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a one-year warranty. Its MTBF exceeds 2 million hours under normal server operating conditions, reflecting high reliability. Actual failure rate is typically less than 0.1% annually.
