Quick Answer: What servers is the MS620-CA compatible with?
The MS620-CA 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 MS620-CA ship?
If in stock, the MS620-CA ships in 1–3 business days. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and pallet orders may need extra handling time; we confirm the ship date with your order.
The MS620-CA 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 MS620-CA?
The MS620-CA is a HP server memory module with capacity 2 GB and number of sticks 4, 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.

Pro Disk Network Buyer’s Guide: Server Memory
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 MS620-CA, 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.
