Quick Answer: What socket does the A3261-60004 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 A3261-60004 ship?
If in stock, the A3261-60004 ships same business day on US orders placed before 2 pm ET. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and project orders shipping in pallets are typically dispatched within 24-48 hours.
The A3261-60004 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 vSphere ESXi 8 Host — Per-CPU core count drives VVF/VCF licensing cost — choose 16–24 cores for cost-optimal density unless workload is core-bound.
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.
New, Bulk, or Refurbished — Choosing Your Tier
Pro Disk Network offers the A3261-60004 across three procurement tiers. Each tier is fully functional and warranted; the choice comes down to budget, warranty length, and whether the deployment is production-critical or capacity-expansion.

Frequently Asked Questions about A3261-60004
Is the A3261-60004 a genuine HP part?
Yes. Pro Disk Network sources every A3261-60004 as factory-original HP inventory verified against the manufacturer parts registry before listing. 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 12 months.
What socket does the A3261-60004 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 A3261-60004 ship?
If in stock, the A3261-60004 ships same business day on US orders placed before 2 pm ET. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and project orders shipping in pallets are typically dispatched within 24-48 hours.
What is the warranty on the A3261-60004?
New A3261-60004 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 (12 months refurbished, 36 months new bulk). DOA replacement is free within 30 days of receipt.
Do you offer bulk pricing for the A3261-60004?
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.
Socket Compatibility, EVC Mode, and BIOS Revision Planning
Choosing the A3261-60004 for a server upgrade or replacement starts with socket compatibility. CPU sockets are tied to motherboard chipsets and revisions; a board that supports Skylake-SP may or may not support Cascade Lake-SP depending on BIOS. Before ordering, look up the motherboard QVL (qualified vendor list) and confirm the A3261-60004 appears with a supported BIOS version. If the BIOS needs an update, plan the flash before swapping CPUs — many systems will not POST long enough to flash with the wrong CPU installed.
AI Workloads, AMX, and the Inference Performance Story
For dedicated AI inference hosts, prioritize core count over clock speed. INT8 inference is bandwidth-bound, not frequency-bound, so a 32-core part at 2.5 GHz outperforms a 16-core part at 3.5 GHz on most LLM workloads. For mixed virtualisation + occasional inference workloads, prioritize clock speed — VDI and OLTP database workloads benefit from the higher frequency.
