AMD OSA2220CXWOF Dual-Core Socket F Server Processor

Overview

The AMD OSA2220CXWOF is a second-generation Opteron 2220 processor built for Socket F (LGA-1207) server and workstation motherboards. It runs a dual-core design at 2.80 GHz with a 1000 MHz HyperTransport link and 2MB of total cache, fabricated on AMD's 90nm process. This SKU ships without a fan ("WOF"), which matters for anyone replacing a CPU in a 1U or 2U chassis that already carries its own heatsink/fan assembly — you're not paying for cooling hardware you can't use. The OSA2220CXWOF is a legacy-platform component: it belongs in maintenance, repair, and lifecycle-extension work on existing Socket F deployments rather than new-build designs, and it should be evaluated against your motherboard's supported CPU list before ordering.

Key Features

• Socket F (LGA-1207) compatibility: This package format matches AMD's dual-processor Opteron server platforms of that generation. If your board's socket is Socket F, the OSA2220CXWOF drops in without a motherboard swap — the fastest, lowest-risk way to keep a fleet running past a component failure.
• Dual-core architecture: Two physical cores let the system handle two concurrent threads without relying on simultaneous multithreading tricks — useful for keeping a legacy virtualization host or database server operating at its original design load.
• 2.80 GHz clock speed: Sets the per-core throughput ceiling for this part. On Socket F platforms this sits toward the higher end of the Opteron 2000 series, so a straight swap-in for a lower-clocked 2000-series part is a real performance gain on single-threaded workloads.
• 1000 MHz HyperTransport: Governs the interconnect speed between the CPU, chipset, and (in dual-socket boards) the second processor. A faster HyperTransport link reduces memory and inter-socket latency versus earlier 800 MHz Opteron parts, which matters most in dual-CPU NUMA configurations.
• 2MB total cache: Cuts down on main-memory round trips for working sets that fit inside it, which keeps database and file-serving workloads more responsive on hardware that predates today's larger cache designs.
• 90nm manufacturing process: Reflects the process node of this processor generation. It's a known quantity for thermal and power behavior on Socket F boards designed around that era's TDP envelope, so existing cooling budgets on these platforms remain valid.
• 1.4V DC input voltage: Matches the VRM output range Socket F motherboards of this generation were built to supply. Confirm your board's BIOS/VRM revision supports this voltage before installing, particularly on boards that saw multiple Opteron steppings.
• No fan included (WOF): Keeps the package focused on the processor itself. This is the correct choice when you're reusing an existing heatsink/fan unit pulled from the same socket, and it avoids paying for a cooler that would just be discarded.

Integration & Compatibility

The OSA2220CXWOF is built for Socket F (LGA-1207) motherboards supporting the Opteron 2000 series. Because this generation shipped in both single- and dual-socket board designs, verify whether your platform needs a matched pair for dual-CPU operation — mixing steppings or clock speeds across two sockets is not something to guess at. Check your motherboard manufacturer's CPU support list against the OSA2220CXWOF part number before purchasing, since BIOS microcode revisions on older Socket F boards can gate which Opteron steppings are recognized at POST.

A: Socket F, also known as LGA-1207.

Q: How many cores does the OSA2220CXWOF have?

A: Two physical cores (dual-core).

Q: What is the clock speed of the OSA2220CXWOF?

A: 2.80 GHz per core.

Q: How much cache does the OSA2220CXWOF have?

A: 2MB of total cache.

Q: What HyperTransport speed does the OSA2220CXWOF support?

A: 1000 MHz.

James Everett

The OSA2220CXWOF is a straightforward part once you understand what it's for: keeping an existing Socket F fleet alive. At 2.80 GHz across two cores with 1000 MHz HyperTransport, it's a mid-to-upper tier option within the Opteron 2000 series for anyone doing a like-for-like replacement or a modest clock-speed bump on a dual-socket board.

Technical Highlights:

• 2.80 GHz dual-core: gives each of the two cores a full 2.80 GHz clock, a step up from lower-binned 2000-series parts running at 2.4-2.6 GHz — worth it if your workload is bottlenecked on single-thread performance rather than core count.
• 1000 MHz HyperTransport: on a dual-socket Socket F board, this is the link carrying inter-CPU and memory traffic. Compared to 800 MHz HT parts from earlier Opteron 2000 steppings, it trims a real amount of latency in NUMA-sensitive workloads like database serving.
• 1.4V DC input: stay inside your board's supported VRM range for this voltage — Socket F boards spanned several Opteron steppings, and older BIOS revisions don't always recognize newer ones.

Deployment Considerations:

• This is a WOF (without fan) unit — plan to reuse the heatsink/fan assembly from the outgoing CPU, or source one separately before you're mid-install.
• Confirm your motherboard's BIOS microcode supports this specific stepping of the 2220 before ordering; Socket F boards from this era are not universally forward-compatible across every Opteron revision.

This part fits a narrow but real use case: extending the service life of a dual-socket Socket F virtualization or database host that's still doing its job, where a full platform refresh isn't budgeted this cycle. For anyone specifying new hardware, the OSA2220CXWOF isn't the starting point — it's the fix for keeping OSA2220CXWOF-class hardware running one more cycle.
