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 19K3388 ship?
19K3388 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 19K3388 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 19K3388?

Frequently Asked Questions about 19K3388
Is the 19K3388 a genuine IBM part?
Yes. Pro Disk Network sources every 19K3388 as factory-original IBM inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned IBM servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What socket does the 19K3388 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 19K3388 ship?
19K3388 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.
What is the warranty on the 19K3388?
New 19K3388 units carry the full IBM 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.

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 19K3388 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 19K3388 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.
