The P-SDHC4G4X2-EF (P-SDHC4G4X2-EF - PNY Optima 4GB Class 4 SDHC Flash Memory Card) is a Flash Memory component engineered for sustained enterprise-class workloads. This part addresses common procurement scenarios where exact-match replacement, capacity expansion, or new-build deployment is required. Technical specifications include capacity of 4 GB. Common deployment scenarios include database server upgrades (in-memory caches, SQL buffer pools), VMware ESXi / Hyper-V virtualization host memory expansion, GPU compute scratch pools, and HPC node provisioning. Pro Disk Network maintains the P-SDHC4G4X2-EF in our enterprise inventory and verifies each unit against manufacturer datasheet specifications prior to listing. New stock ships factory-sealed where available; refurbished units are tested under load before dispatch and ship with a 90-day Pro Disk Network functional warranty. Same-day dispatch on in-stock orders placed before 3pm ET; free standard ground shipping on US orders over $150.
The P-SDHC4G4X2-EF is a enterprise-grade flash memory component with capacity 4 GB. Pricing on the P-SDHC4G4X2-EF is quote-based — email sales@prodisknetwork.com or use our live chat for a quote within one business day.

Quick Answer: What servers is the P-SDHC4G4X2-EF compatible with?
The P-SDHC4G4X2-EF is a flash memory module. Confirm DIMM rank, voltage, and speed against the target server's supported memory list before deployment - mixed configurations may downclock to the slowest installed module. For server-specific population diagrams, email sales@prodisknetwork.com with your server serial number.
How fast does the P-SDHC4G4X2-EF ship?
If in stock, the P-SDHC4G4X2-EF ships same business day on US orders placed before 3 pm ET. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and project orders shipping in pallets are typically dispatched within 24-48 hours.
The P-SDHC4G4X2-EF is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
VMware Cluster Memory — Per-host memory expansion for vSphere ESXi hosts. Match DIMM rank and speed across all sockets to keep memory channels balanced.
In-Memory Database — SAP HANA, Redis Enterprise, Apache Ignite, Aerospike — workloads that scale linearly with DRAM capacity.
Hyper-V Cluster Node — Windows Server 2019/2022 Hyper-V hosts with Storage Spaces Direct. Dynamic memory allocation makes higher-density DIMMs cost-effective.
AI / ML Training — PyTorch and TensorFlow workloads benefit from large host memory pools for dataset preprocessing and CPU-side feature engineering.
What is the P-SDHC4G4X2-EF?
The P-SDHC4G4X2-EF is a server memory module with capacity 4 GB, manufactured for enterprise IT deployments. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with same-day dispatch on orders placed before 3 PM ET, backed by a 30-day return guarantee.
Pros & Cons of P-SDHC4G4X2-EF
Pros
RDIMM / LRDIMM clearly labelled for population-rule clarity
Cons
Memory must match existing DIMM rank/density for channel balance
Higher density modules can drop overall channel speed
BIOS update may be required on older revisions
Frequently Asked Questions about P-SDHC4G4X2-EF
Is the P-SDHC4G4X2-EF a genuine part?
Yes. Pro Disk Network sources every P-SDHC4G4X2-EF as factory-original inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.

Compatibility: Rank, Density, and Channel Population Rules
For server memory, three numbers dominate compatibility: rank, density, and channel population. Mixing rank or density in the same channel forces the memory controller to fall back to the lowest-common-denominator speed and timings, sometimes by 200-400 MHz, which wastes the upgrade you just paid for. Before installing the P-SDHC4G4X2-EF, run the platform's memory configuration utility (Dell DSET, HPE iLO Memory tab, Lenovo XCC Memory page) to identify what's already populated.
Pricing Strategy: New, Bulk, or Refurbished
For production tier-1 databases (SAP HANA, Oracle Exadata-equivalent, SQL Server Always On), use new sealed OEM units only. For VDI hosts, hyperconverged clusters, and general-purpose virtualisation, bulk-OEM is the cost-optimal choice. For development environments, lab gear, and capacity expansion on aging hardware, refurbished is appropriate — the price savings are 60-75% versus new.
