Quick Answer: What servers is the KVR400-256R compatible with?
The KVR400-256R is a Kingston 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 KVR400-256R ship?
KVR400-256R orders placed before 2 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 KVR400-256R 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.

Frequently Asked Questions about KVR400-256R
Is the KVR400-256R a genuine Kingston part?
Yes. Pro Disk Network sources every KVR400-256R as factory-original Kingston inventory verified against the manufacturer parts registry before listing. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Kingston servers, surface-tested, and re-warranted by Pro Disk Network for 12 months.
What servers is the KVR400-256R compatible with?
The KVR400-256R is a Kingston 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 KVR400-256R ship?
KVR400-256R orders placed before 2 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 KVR400-256R?
New KVR400-256R units carry the full Kingston manufacturer warranty (typically 1 to 5 years depending on product line). Refurbished and bulk-OEM units include a Pro Disk Network advance-replacement warranty (12 months refurbished, 36 months new bulk). DOA replacement is free within 30 days of receipt.
Do you offer bulk pricing for the KVR400-256R?
Yes. Pro Disk Network offers automatic volume discounts at 10, 25, 50, and 100+ unit tiers. Net 30 terms are available for verified businesses, government, and education buyers. Email sales@prodisknetwork.com with the quantity and target ship date for a quote within one business day.
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 KVR400-256R 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+ and offers Net 30 to verified business buyers.
