AMD OS4180WLU6DGO 2.6GHz Hexa-Core Socket C32 Server Processor

Overview

The AMD OS4180WLU6DGO is an Opteron 4100 series (model 4180) hexa-core server processor built for Socket C32 platforms that need multi-threaded headroom without the power draw of a higher-TDP part. It runs six cores at 2.60 GHz with a 6 MB L3 cache shared across the die, giving it enough parallel throughput for virtualization hosts, small-to-midsize database servers, and edge compute nodes where rack power and cooling budgets are fixed. At 75W TDP, the OS4180WLU6DGO fits into 1U and 2U chassis where thermal headroom is tight, and its OLGA-1207 packaging drops directly into existing Socket C32 boards without a socket adapter.

Key Features

• Hexa-Core (6 Core) design: Six physical cores let you run more concurrent VMs or worker threads per socket than a quad-core Opteron, which matters when you're consolidating older single-purpose servers onto fewer physical boxes.
• 2.60 GHz clock speed: Delivers consistent per-core throughput for latency-sensitive workloads like directory services and small SQL instances, without the clock variability you get from turbo-boosting parts under sustained load.
• 6 MB L3 cache: A shared last-level cache this size cuts memory-controller round trips on multi-threaded workloads, which keeps performance steadier under mixed application loads than a smaller-cache SKU.
• 3 MB L2 cache: Backs the L3 with fast mid-tier storage per core cluster, reducing stalls on branch-heavy code common in database and virtualization workloads.
• 768 KB L1 cache: The tightest, fastest cache tier on the die — keeps hot instruction and data paths close to the execution units for workloads with repetitive access patterns.
• 64-bit processing: Required baseline for any current 64-bit hypervisor or server OS — no compatibility concerns running modern virtualization stacks built for this architecture generation.
• 45nm process technology: A mature, well-characterized fabrication node — the OS4180WLU6DGO's power and thermal behavior is predictable, which simplifies capacity planning in mixed-generation racks.
• 75W Thermal Design Power: Meaningfully lower than higher-clocked Opteron 4100 variants, so it's a fit for density-constrained chassis or racks where you're already close to your PDU or CRAC limits.
• Socket C32 OLGA-1207 package: Drop-in compatible with existing Socket C32 motherboards — no board redesign needed if you're refreshing processors in a fleet that already standardized on this socket.
• 1.4V DC input voltage: Standard voltage rail for this processor family, simplifying VRM and power-delivery planning on Socket C32 boards already provisioned for Opteron 4100-series parts.
• 158°F (70°C) thermal specification: Defines your safe operating ceiling for airflow design — plan chassis fan curves and ambient intake temps to stay under this threshold for sustained reliability.

Integration & Compatibility

The OS4180WLU6DGO is built for Socket C32 OLGA-1207 motherboards used in AMD Opteron 4100-series servers — confirm your board's socket revision and BIOS microcode support before ordering, since Socket C32 boards varied by OEM and generation. It's a straight fit for refreshing or expanding capacity in an existing Opteron 4100 deployment, letting you standardize spare inventory across a rack of matching boards rather than stocking parts for multiple socket generations. Buyers researching this part also search it as OS4180WLU6DGO or the stripped variant OS4180WLU6DGO without hyphens — same processor, same SKU.

The OS4180WLU6DGO is a 75W hexa-core Opteron that I'd spec for a rack where power budget matters more than raw clock speed. Six cores at 2.60 GHz with a 6 MB L3 cache gives it enough headroom for consolidated VM hosts without pushing chassis thermals the way a 95W+ SKU in this family would.

Technical Highlights:

• 6 MB L3 / 3 MB L2 / 768 KB L1 cache hierarchy: the shared 6 MB L3 keeps multi-core workloads from thrashing memory controllers, a real factor once you're running 4+ VMs per socket.
• 75W TDP: roughly 20-25% lower than higher-binned Opteron 4100 parts, which buys you real headroom in density-constrained 1U deployments.
• 1.4V DC / 45nm process: a mature, predictable power-and-thermal profile — no surprises when planning VRM loads across a rack of matching boards.

Deployment Considerations:

• Confirm BIOS microcode support for the 4180 on your specific Socket C32 board revision before deploying — Opteron 4100-series compatibility varied by OEM firmware version.
• Watch out: at 158°F (70°C) thermal spec, this part needs adequate chassis airflow in 1U deployments where intake temps run warm — don't assume passive cooling margins from a 2U build carry over.

This is the right pick for refreshing an existing Opteron 4100 / Socket C32 fleet where you need to add hexa-core capacity to virtualization or database hosts without exceeding a 75W-per-socket power ceiling — not a fit if you're building new infrastructure from scratch, where current-generation platforms make more sense.
