The Dell K5773 (K5773 - Dell 1.40GHz 400MHz FSB 4MB L3 Cache Intel Itanium-2 Processor for PowerEdge 3250) is a Intel Unboxed Processors 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 clock speed of 1.40 GHz, bus speed of 400 MHz FSB, cache of 4MB L3. Workload fit covers VMware ESXi virtualization hosts (vCPU density), SQL Server / Oracle database licensing optimization (per-core), Kubernetes container density, and HPC compute-node provisioning. Pro Disk Network sources the K5773 through reputable distribution channels and applies a verification check against the OEM compatibility matrix before each unit is added to active inventory. Each unit ships from a US fulfillment hub (Hillsboro OR, Atlanta GA, or Phoenix AZ) with same-day dispatch on in-stock orders before 3pm ET. 90-day Pro Disk Network functional warranty included; free US ground shipping on orders over $150.

Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids). A BIOS update is often required for newer steppings even on the same socket. Email sales@prodisknetwork.com with your motherboard model for a compatibility check.
How fast does the K5773 ship?
K5773 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 K5773 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.
Hyper-V Cluster Node — Windows Server Datacenter licenses by core, but Hyper-V scales linearly. Higher-clock, mid-core SKUs win for transactional workloads.
Citrix VDI Pool — Frequency-sensitive — prefer high-clock 16–18 core SKUs over high-core-count parts to maintain user-perceived snappiness.
Kubernetes / Tanzu Workers — Higher core count amortises better across many small Pods. EVC mode planning matters for live-migrate parity.
AI Inference Host — Sapphire Rapids and Emerald Rapids include AMX silicon for INT8 inference acceleration — meaningful uplift for BERT, ResNet, and LLM serving.
What is the K5773?
The K5773 is a Dell server-class processor with clock speed 1.40 GHz and bus speed 400 MHz FSB, manufactured by Dell. 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 K5773
Pros
Lower cost than the manufacturer channel for refresh cycles
Matched-pair option for dual-socket consistency
Sequential serial numbers on bulk orders for cluster builds
Cons
Older microarchitecture — not appropriate for new AI/AMX workloads
Not always silicon-binned for overclocking
Stepping mismatch with newer revisions can require microcode update
Frequently Asked Questions about K5773
Is the K5773 a genuine Dell part?
Yes. Pro Disk Network sources every K5773 as factory-original Dell inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Dell servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What socket does the K5773 use?
Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids). A BIOS update is often required for newer steppings even on the same socket. Email sales@prodisknetwork.com with your motherboard model for a compatibility check.
How fast does the K5773 ship?

What is the warranty on the K5773?
New K5773 units carry the full Dell 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.

Pro Disk Network Buyer’s Guide: Intel Unboxed Processors
Socket Compatibility, EVC Mode, and BIOS Revision Planning
For VMware vSphere clusters, EVC (Enhanced vMotion Compatibility) mode dictates which CPU generations can coexist in the same cluster while still supporting live migration. Adding a newer-generation K5773 to a cluster with older CPUs requires setting EVC to the older baseline, which disables newer instructions on the new CPU. Plan EVC mode at cluster creation time; changing it later requires powering off the cluster.
AI Workloads, AMX, and the Inference Performance Story
Plan memory bandwidth alongside the CPU: AMX inference is memory-bandwidth sensitive. A K5773 paired with insufficient memory channels (e.g., DDR5-4800 in fewer than 8 channels per socket) will underperform its theoretical peak by 30-40%. Confirm motherboard channel count and DIMM population before ordering.
