AMD OSA8220GAA6CY Dual-Core Server Processor

The AMD OSA8220GAA6CY is an Opteron 8220 series server processor built around a dual-core design clocked at 2.80GHz, targeting Socket F server platforms that need a direct drop-in replacement or an upgrade path for an existing multi-socket deployment. If you're maintaining legacy HPE, IBM, or Sun/Oracle server chassis built on the Socket F platform, this is a component-level part — sourced to replace a failed CPU or to populate an open socket on a board that's already qualified for the Opteron 8000 series. The OSA8220GAA6CY is not a repackaged consumer chip; it carries the server-specific power and cache profile the Opteron 8220 line was built for.

Overview

This part occupies a specific niche: keeping existing multi-socket server infrastructure running without a full platform refresh. When a Socket F board is already paid for, qualified, and running production workloads, swapping in another OSA8220GAA6CY unit is far less disruptive than a motherboard-level upgrade. That makes this processor relevant to data center technicians, IT asset recovery shops, and integrators supporting older HPE ProLiant or third-party Opteron-based servers still in service.

Key Features

• 2.80GHz Clock Speed: Delivers the core processing throughput this Opteron 8220 revision was rated for — matched clock speed across sockets matters on multi-CPU boards, since mismatched Opteron steppings can cause instability or force a downclock on the whole system.
• Dual-Core Architecture: Two physical cores per socket means a 4-socket Socket F server populated with these parts reaches 8 total cores — relevant for older virtualization hosts or database servers where core count, not raw clock speed, was the original sizing metric.
• 2MB Processor Cache: On-die cache of this size reduces main-memory round-trips for the working data sets typical of the era's server workloads, which keeps replacement performance consistent with the rest of a matched-socket server rather than introducing a cache-size mismatch across CPUs.
• 95W Processor Power (TDP): A 95W thermal envelope is what the original Socket F server chassis and heatsinks were engineered around — dropping in a processor at this same TDP means existing cooling and power delivery stay within spec, with no airflow or PSU re-validation needed.
• Socket F Package: Confirms mechanical and pin compatibility with Socket F (1207-pin LGA) server boards — verify your motherboard's socket revision and BIOS Opteron support list before ordering, since Socket F spans several Opteron generations.
• Opteron Server Family: Positions this part specifically for server and workstation boards validated for AMD's Opteron line, not desktop AM2/AM3 platforms — the memory controller, HyperTransport links, and multi-socket coherency logic are server-class features not found in consumer Athlon-era parts.

Integration & Compatibility

Compatibility with Socket F motherboards is the deciding factor here — confirm your server vendor's BIOS/firmware Opteron 8220 support before purchasing, since Socket F server boards typically publish a validated CPU list. For multi-socket servers, match stepping and revision across all installed CPUs where possible to avoid the platform capping clock speed to the lowest common denominator. This processor pairs with the same registered ECC memory and chipset infrastructure already in place on qualified Opteron 8000-series boards — no separate driver or firmware package is tied to the CPU itself beyond a BIOS microcode update if your board requires one for this stepping.

Frequently Asked Questions

Q: What's the power draw (TDP) of the OSA8220GAA6CY?

A: 95W.

Q: Will the OSA8220GAA6CY work in any server?

A: Only in servers with a Socket F CPU socket and BIOS/firmware validated for the Opteron 8220 — check your server vendor's supported-CPU list before ordering.

The OSA8220GAA6CY comes up constantly in tickets from shops keeping older multi-socket Opteron servers alive — this is the Opteron 8220, a dual-core Socket F part running 2.80GHz with 2MB of cache and a 95W TDP.

Technical Highlights:

• 2.80GHz / dual-core: in a 4-socket board this gets you 8 cores total — that was real headroom for the virtualization hosts these Opteron 8000-series boards were built for.
• 2MB cache: matches the on-die cache spec of the original Opteron 8220 stepping, so you're not introducing a cache mismatch if you're populating additional sockets on an already-running server.
• 95W TDP: stays inside the thermal envelope the Socket F chassis and heatsink were designed for — no cooling re-validation needed on a straight swap.

Deployment Considerations:

• Before ordering, confirm your board's BIOS support list explicitly lists the Opteron 8220 — Socket F spans multiple Opteron generations and not every board flashes support for every stepping.
• On multi-socket boards, mismatched CPU steppings across sockets can force the platform to downclock every installed processor to the slowest one present — match steppings where you can.

This is the right call for a data center tech doing a like-for-like CPU swap on a Socket F Opteron 8000-series server that's already in production — not for anyone speccing new server hardware.
