D32.31301S.001 Présentation
DDR5 SDRAM is the fifth-generation Double Data Rate Synchronous DRAM standard that doubles the per-pin bandwidth of DDR4 by using on-die ECC, decision feedback equalization (DFE), and a 32-bit channel architecture with separate CA/CS sub-channels. A DIMM (Dual In-Line Memory Module) is a printed circuit board that carries SDRAM chips and plugs into a host board memory socket; UDIMM variants omit the register/buffer and are the standard form factor for workstations and servers that do not require fully buffered modules. The D32.31301S.001 fits the ECC UDIMM sub-category, adding parity-style error correction that is critical for server workloads and EEC-aware workstation platforms.
Key features include the DDR5-4800 data rate (4800 MT/s, equivalent to 38.4 GB/s per module theoretical bandwidth), CL40 CAS latency, 288-pin UDIMM edge connector with 1.1 V VDD / 1.8 V VPP operation, and the on-module 8 Kbit SPD EEPROM that enumerates JEDEC-compliant timings to the system BIOS at power-on. The 288-pin UDIMM form factor follows the JEDEC MO-309A mechanical outline, allowing the module to be installed in any DDR5 UDIMM socket that supports ECC.
The module follows the JEDEC DDR5 standard (JESD79-5) for SDRAM protocol, command/address topology, and PMIC integration. Apacer's industrial-grade screening and the SA-HF (solder assembly, halogen-free) designation indicate compliance with RoHS 2.0 and halogen-free PCB requirements, while the 1.1 V nominal operation reduces module power versus DDR4's 1.2 V supply, despite the doubled bandwidth.
Typical applications include server-class workstation memory upgrades, edge-computing appliances, single-socket server boot/main memory banks, virtualization hosts, in-memory database workloads, and ECC-required development platforms. The 32 GB density is a sweet spot for workloads that exceed 16 GB but do not need full 64 GB+ populations.
Design considerations include host platform DDR5 UDIMM socket validation, BIOS SPD recognition of the Apacer vendor ID, and case-by-case thermal profiling: modules running sustained DDR5-4800 with ECC error correction can dissipate 6-9 W per module and benefit from chassis airflow.

Applications typiques
D32.31301S.001 convient pour 6 applications: Single-Socket Workstation Memory Upgrade, Edge-Compute Appliance Main Memory, Virtualization and Cloud Server Memory, In-Memory Database Workloads, AI Inference Server Memory Bank, Development and Validation Platform Memory.
Single-Socket Workstation Memory Upgrade
The Apacer D32.31301S.001 is an ideal drop-in upgrade for single-socket workstations running CAD, EDA, or content-creation workloads that demand more than 16 GB but do not need fully buffered memory. The 32 GB DDR5-4800 capacity doubles memory headroom for large project files, while ECC corrects the single-bit memory faults that long compile or render jobs are statistically likely to encounter. With a 288-pin UDIMM form factor, the module plugs into any DDR5 ECC UDIMM socket without BIOS modification when the Apacer vendor ID is accepted by the SPD whitelist.
Recommandé
Edge-Compute Appliance Main Memory
Edge-compute appliances - industrial PCs, AI inference boxes, and ruggedized servers - require ECC memory because they often run unattended in factories or outdoor cabinets where a single-bit memory fault would otherwise crash the system. The Apacer D32.31301S.001 provides 32 GB of DDR5-4800 bandwidth at 1.1 V, which keeps total module power around 6-9 W per DIMM and reduces cooling burden in sealed enclosures. The SA-HF (solder assembly, halogen-free) PCB and JEDEC-compliant SPD profile make it suitable for industrial temperature screening when the host platform supports the same envelope.
Recommandé
Virtualization and Cloud Server Memory
Virtualization hosts and small-to-mid cloud servers benefit from ECC-protected memory because hypervisors can correct single-bit faults without crashing guest VMs, dramatically improving uptime SLAs. The Apacer D32.31301S.001's 32 GB density suits typical VM density targets (8-12 small VMs per 32 GB host), while DDR5-4800 (4800 MT/s) per-pin bandwidth keeps vCPU-to-memory throughput high. ECC UDIMM is supported by mainstream server platforms from Intel (W680, C621) and AMD (WRX80), and the module conforms to JEDEC JESD79-5 DDR5 electrical specifications.
Recommandé
In-Memory Database Workloads
In-memory databases such as Redis, Memcached, SAP HANA, and TimeScaleDB demand both high memory bandwidth and ECC to protect the working dataset from silent corruption. The Apacer D32.31301S.001's 32 GB DDR5-4800 ECC UDIMM profile delivers ~38.4 GB/s of theoretical memory bandwidth per module, well matched to the per-socket bandwidth needs of in-memory key-value stores. ECC plus the JEDEC-compliant SPD allow the host memory controller to perform error correction at full speed without throughput penalty.
Recommandé
AI Inference Server Memory Bank
DDR5 ECC UDIMMs are a cost-effective memory tier for AI inference servers that do not require HBM bandwidth but do benefit from ECC protection during long inference jobs. The Apacer D32.31301S.001 provides 32 GB per module with DDR5-4800 throughput, allowing multi-module configurations (4 or 8 DIMMs) to feed modern CPU inference pipelines with hundreds of GB/s of memory bandwidth. The ECC capability is critical when running quantized model weights that occupy large memory regions for extended periods.
Recommandé
Development and Validation Platform Memory
Memory validation labs and DDR5 controller developers use modules like the Apacer D32.31301S.001 as known-good reference DIMMs during bring-up, jitter margining, and signal-integrity characterization. The module's strict adherence to the JEDEC DDR5 standard (JESD79-5) plus the JEDEC MO-309A mechanical outline makes it a clean baseline against which new memory controllers, PMICs, and RCD-less UDIMM designs can be validated. ECC enables the test firmware to inject single-bit errors and confirm the controller's correction path.

Notes de conception
The D32.31301S.001 follows the JEDEC MO-309A 288-pin UDIMM mechanical outline with a single key notch between pins 96 and 97. When validating a host board, confirm the memory socket is rated for DDR5 UDIMM (not SO-DIMM or RDIMM) and that ECC pin routing to the CPU memory controller is present; many consumer desktop boards omit ECC pin connections even though the socket physically accepts the module. Validate against the platform QVL before procurement.
DDR5-4800 ECC UDIMMs typically dissipate 6-9 W per module at full throughput. In a 4 or 8 DIMM populated workstation, total memory power can exceed 50 W, which mandates directed chassis airflow and DIMM-slot spacing that complies with JEDEC thermal envelopes. In sealed enclosures, install a low-noise fan pulling air across the DIMM bank; in passive enclosures, derate the modules to DDR5-4400 or DDR5-4000 to lower thermal output.
Do not mix the D32.31301S.001 with non-ECC DDR5 UDIMMs in the same memory channel - the host memory controller's ECC logic assumes a consistent ECC/non-ECC population per channel, and mixed populations will typically drop the entire channel to non-ECC operation. Also confirm BIOS revision supports DDR5-4800; older BIOS revisions may downclock to DDR5-4400. Apacer SPD timing values are read from the on-board 8 Kbit EEPROM at POR and must be in the BIOS whitelist for full speed operation.
DDR5 moves voltage regulation from the motherboard to on-module PMICs (per JEDEC DDR5 standard). The D32.31301S.001 hosts its own PMIC that converts a 5 V or 12 V bulk rail into the 1.1 V VDD and 1.8 V VPP required by the DRAMs. Host board designs must provide sufficient bulk decoupling and follow Apacer's recommended bulk-cap layout near the DIMM slot. Skipping bulk caps can cause VPP droop during write bursts that triggers DRAM errors.
