About the D9503A
Sourced for enterprise IT teams, the HP D9503A (D9503A - HP 256MB RDRAM-700MHz PC700 non-ECC 184-Pin RIMM Memory Module) is a Rambus Memory (RDRAM) component appropriate for new-build, expansion, or warranty-replacement procurement. Technical specifications include capacity of 256 MB, number of sticks of 1, frequency of 700 MHz, connector of 184-pin, memory class of ECC. Appropriate for virtualization hosts, application servers, in-memory analytics, render farms, CAD/EDA workstations, and any workload constrained by RAM rather than CPU. Pro Disk Network maintains the D9503A 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. Dispatch in 1–3 business days; free standard ground shipping on US orders over $150.
The D9503A is a HP rambus memory (rdram) component with capacity 256 MB, number of sticks 1, frequency 700 MHz. Pro Disk Network sells the D9503A for $186.06 with US shipping in 1–3 business days and a 30-day return guarantee.
Quick Answer: What servers is the D9503A compatible with?
The D9503A is a HP rambus memory (rdram) 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 D9503A ship?
D9503A orders ship in 1–3 business days from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The D9503A 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.
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.
Tanzu / Kubernetes Workers — Worker node memory expansion for high-density container deployments. Plan for 8–16 GB per moderate Pod baseline.
What is the D9503A?
The D9503A is a HP server memory module with capacity 256 MB and number of sticks 1, manufactured by HP. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with dispatch in 1–3 business days, backed by a 30-day return guarantee.

Frequently Asked Questions about D9503A
Is the D9503A a genuine HP part?
Yes. Pro Disk Network sources every D9503A as factory-original HP inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned HP servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What servers is the D9503A compatible with?
The D9503A is a HP rambus memory (rdram) 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.

Pro Disk Network Buyer’s Guide: Rambus Memory (RDRAM)
Compatibility: Rank, Density, and Channel Population Rules
Quad-rank modules behave differently from dual-rank: most modern Xeon platforms support 1-2 DPC (DIMMs per channel) at full speed with single- and dual-rank modules but downclock with quad-rank above 1 DPC. RDIMM and LRDIMM are not interchangeable in the same channel. ECC and non-ECC cannot be mixed. Server motherboards expect server DIMMs — the D9503A is a server module and will not work in consumer desktop boards.
Pricing Strategy: New, Bulk, or Refurbished
If you are buying 16 or more modules at once, request a matched-lot quote: sequential manufacturing dates and serial numbers, which reduces variance in observed memory speeds across the channel. Pro Disk Network ships matched-lot orders for free on volumes of 16+.
