D32.35303H.001 개요
A DDR5 SDRAM module is a synchronous dynamic random-access memory module built to the JEDEC DDR5 specification. Within the system memory hierarchy, DDR5 sits above LPDDR5 (mobile) and below HBM (high-bandwidth memory), delivering roughly double the per-pin transfer rate of DDR4 while reducing the per-channel voltage from 1.2 V to 1.1 V. As ECC (Error-Correcting Code) memory, it adds single-bit error correction to mainstream server-class reliability, addressing multi-bit soft errors common in densified DRAM arrays. The 288-pin UDIMM form factor is the standard desktop/workstation DIMM, distinguishable from RDIMMs by its lack of a register clock driver, allowing lower latency at the cost of reduced maximum rank count per channel.
Key features of the D32.35303H.001 include 32 GB density, 5600 MT/s data rate (PC5-44800), CL46 CAS latency, on-module voltage regulation via a 12V-to-1.1V PMIC, ECC for single-bit error correction, and a halogen-free VLP height that fits 1U server chassis. The 2048x8 DRAM organization (twenty 2Gx8 devices) provides x8 data width with ECC bits distributed across the DRAM array. The Hynix die suffix indicates the underlying memory supplier.
In use, this module is recommended for single-CPU workstations, edge servers, and industrial PCs that need ECC error correction without paying the latency penalty of registered memory. The 5600 MT/s speed places it at the high end of mainstream DDR5 server-class throughput, suitable for virtualization hosts, in-memory databases, and content-creation workstations handling 4K/8K media.
When designing with VLP UDIMMs, confirm the chassis DIMM slot height: standard VLP modules measure 18.3 mm tall (versus 31.25 mm for full-height DIMMs). Older chassis with tall heatsink shrouds may not accept VLP modules. The on-module PMIC requires the host 12V rail to remain within ±5% tolerance.

일반적인 애플리케이션
D32.35303H.001 적합 용도: 6 애플리케이션s: 1U Rack Server Memory, Edge Computing Platforms, Workstation Memory Upgrades, In-Memory Database Workloads, Telecommunications Infrastructure, Medical Imaging Systems.
1U Rack Server Memory
The D32.35303H.001's Very Low Profile (VLP) 18.3 mm height allows it to fit the tight DIMM clearances inside 1U rack-server chassis where full-height 31.25 mm DIMMs would conflict with airflow shrouds. Its 32 GB density and 5600 MT/s PC5-44800 transfer rate deliver approximately 44.8 GB/s per module, supporting typical web-tier and virtualization server workloads. ECC (single-bit error correction) protects against the elevated soft-error rates seen in densely packed server DRAM arrays, while the on-module PMIC isolates the host 12V rail and improves power efficiency versus discrete regulation. Platform validation against your server's QVL is recommended.

Edge Computing Platforms
Edge deployments in space-constrained cabinets benefit from the D32.35303H.001's VLP form factor combined with 32 GB of ECC memory. The 5600 MT/s data rate delivers mainstream DDR5 bandwidth without the latency penalty of registered DIMMs, important for AI inference accelerators that sit closer to the edge. ECC corrects single-bit memory faults that are increasingly common at industrial thermal envelope operation (0°C to 85°C case range). Pairing with a fanless industrial host keeps noise, dust, and maintenance low while still supporting memory-rich processing.
추천
Workstation Memory Upgrades
For single-CPU workstations handling large datasets, 4K/8K video editing, or CAD/CAE simulation, the D32.35303H.001 delivers 32 GB of ECC UDIMM at the high end of mainstream DDR5 throughput. PC5-44800 speeds improve render times by approximately 5-10% over PC5-38400 baselines. ECC catches single-bit memory errors that would otherwise corrupt long-running simulation outputs. Verify workstation motherboard support for unbuffered ECC before purchase, since some consumer chipsets disable ECC at the controller level.
추천
In-Memory Database Workloads
Databases such as Redis, SAP HANA, and Memcached are sensitive to memory bandwidth and latency. The D32.35303H.001's 5600 MT/s PC5-44800 speed and 32 GB density in a single module reduce DIMM slot count versus lower-density modules, leaving more DIMM banks for expansion. ECC corrects the silent bit-rot that would otherwise corrupt long-term in-memory state in write-heavy workloads. The VLP form factor supports dense platform configurations where multi-DIMM deployments need physical clearance.
추천
Telecommunications Infrastructure
Telecom and networking equipment operating at the network edge often requires 1U form factors with reliable ECC memory. The D32.35303H.001's halogen-free VLP UDIMM form factor meets both the mechanical constraints and the component disclosure requirements common in telecom-class platforms. The JEDEC DDR5 standard, on-module PMIC, and 1.1V core voltage ensure compatibility with the latest server-class networking SoCs. ECC corrects single-bit errors from cosmic-induced upsets that are more common at high-altitude deployments.
추천
Medical Imaging Systems
Medical imaging equipment, including CT/MRI reconstruction workstations and PACS servers, requires both high memory bandwidth and error-correction capability. The D32.35303H.001's 32 GB density and 5600 MT/s speed deliver the throughput needed for real-time volumetric reconstruction, while ECC prevents silent data corruption in patient records and diagnostic outputs. VLP height supports integration into compact cart-based medical imaging carts where full-height DIMMs would obstruct the chassis.

설계 노트
Estimated: at full 5600 MT/s throughput with all 20 DDR5 devices active, the D32.35303H.001 module dissipates approximately 4-5W during sustained reads. VLP modules have reduced surface area for passive cooling; in a 1U chassis with 8-16 populated DIMM slots, validate thermal margin by monitoring DIMM sensor (TSOD) readings during stress workloads. Above 70°C on the module sensor, consider chassis airflow tuning or moving to RDIMM with mirrored heat spreaders.
DDR5 mandates an on-module 12V-to-1.1V PMIC. Verify that your host platform's DIMM slot supplies a regulated 12V rail with ±5% tolerance, since out-of-tolerance input to the on-module PMIC can trigger module fault indicators (ALERT_n). The PMIC handles inrush current; do not place additional capacitance on the host side beyond what the JEDEC reference design recommends, or the module's current ramp may exceed PMIC limits and trigger a fault.
Do not mix UDIMM and RDIMM modules in the same channel - the host memory controller will not interleave them and may fail to boot. Some motherboards also lock ECC error reporting behind a BIOS setting that defaults to disabled; enable 'ECC Enable' or 'ECC Reporting' in the BIOS before expecting ALERT_n signals from the module. The VLP 18.3 mm height may conflict with aftermarket tall heat spreaders used for memory overclocking; design the chassis clearance for VLP.
The 288-pin DDR5 UDIMM slot has a keyed insertion point that prevents reversed installation. However, the on-module PMIC draws a 12V rail that must remain stable during hot-insertion; do not install or remove this module while the host system is powered. Some platforms support hot-swap DIMM replacement for serviceability - confirm this feature is enabled in the BIOS before deploying in a serviceable chassis.
규정 준수 정보
RoHS compliant and halogen-free (HF suffix in MPN) per the Apacer datasheet. Memory modules are typically not subject to AEC-Q100 since they are not automotive discrete semiconductors; contact Apacer for automotive-grade DDR5 SKUs separately. No REACH or conflict minerals statement in the verified web data; set to 'unknown' rather than fabricate.
