Quick Answer: What servers is the 604504B21SSC compatible with?
The 604504B21SSC is a HP server 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 604504B21SSC ship?
604504B21SSC orders placed before 3 pm ET ship the same business day 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 604504B21SSC 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 604504B21SSC?
The 604504B21SSC is a HP server memory module with capacity 4 GB and pc standard PC3-10600, manufactured by HP. 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 604504B21SSC
Pros

Same-day US shipping cuts deployment lead time
Cons
Not for laptop SO-DIMM upgrades — server DIMM only
LRDIMM and RDIMM are not interchangeable
Original retail box not always included on refurbished tier
Frequently Asked Questions about 604504B21SSC
Is the 604504B21SSC a genuine HP part?
Yes. Pro Disk Network sources every 604504B21SSC 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 604504B21SSC compatible with?
The 604504B21SSC is a HP server 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 604504B21SSC ship?
604504B21SSC orders placed before 3 pm ET ship the same business day 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.
What is the warranty on the 604504B21SSC?
New 604504B21SSC units carry the full HP manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (90 days refurbished). DOA replacement is free within 30 days of receipt.

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 604504B21SSC 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+.
