AMD OSA8212GAA6CR Dual-Core Server Processor

Overview

The AMD OSA8212GAA6CR is an Opteron 8212 dual-core server processor built on Socket F (LGA-1207), running at a fixed 2.20 GHz. It targets legacy multi-socket server platforms and workstation refresh/repair projects where the existing motherboard and chassis are staying in service and the CPU is the failed or missing component. This is a replacement-part purchase, not a new-build platform decision — the buyer already owns Socket F infrastructure and needs a matching, functional part.

Key Features

• Socket F (LGA-1207) package: This is a drop-in electrical and mechanical match for existing Socket F server boards only — it will not physically install into any other socket generation, so confirm your motherboard's socket revision before ordering.
• AMD64 Technology: Native 64-bit instruction support, which matters if the server is running a 64-bit OS or hypervisor that expects full AMD64 addressing rather than 32-bit-only compatibility mode.
• Dual-Core design: Two physical cores per socket. In a 2-socket or 4-socket Opteron 8000-series board, this multiplies out to 4 or 8 total cores system-wide, which is the practical reason legacy multi-socket platforms used the 8000 series over single-socket parts.
• 2.20 GHz clock speed: A fixed, non-turbo clock — plan capacity around this number directly rather than assuming dynamic boost headroom that later Opteron generations introduced.
• 1000 MHz HyperTransport: This is the inter-socket and chipset interconnect speed. On multi-socket boards, HyperTransport bandwidth directly affects how well memory and I/O traffic scales as you add sockets — 1000 MHz keeps that overhead in check on 2P/4P designs built for this generation.
• 2MB cache: Shared/total cache on-die reduces trips to main memory for repeat data access, which helps steady-state throughput on server workloads more than it helps single-thread burst performance.
• 90nm process technology: An older fabrication node — expect higher per-core power draw and heat output than later-generation Opterons, which is a real factor in rack thermal budgets when populating multiple sockets with this part.
• 208-230V AC platform voltage: Matches standard high-line commercial power infrastructure used in server-class chassis and PDUs — confirm your rack PDU output matches before deployment.

Integration & Compatibility

The OSA8212GAA6CR is compatible only with Socket F (LGA-1207) motherboards built for the AMD Opteron 8000-series family. Because this is a dual-core part on an older 90nm process, verify your board's BIOS/firmware revision supports this specific Opteron model before purchase — legacy multi-socket boards were frequently validated against a narrow CPU list. If you're sourcing this to replace a failed CPU in a running cluster, matching stepping and confirming existing sibling sockets in the chassis is worth checking against your OEM's supported CPU list prior to installation.

Buyers evaluating options for legacy Socket F platforms should weigh the OSA8212GAA6CR's dual-core, 2.20GHz configuration against other core-count and clock variants in the same Opteron 8000 series — if your workload is more thread-parallel, a higher core-count variant in the same socket family may be a better fit; if it's largely single-threaded, clock speed matters more than core count.

Frequently Asked Questions

Q: What socket does the AMD OSA8212GAA6CR use?

A: Socket F (LGA-1207). It only installs in motherboards built for that socket.

Q: Is the OSA8212GAA6CR a single-core or dual-core processor?

A: Dual-core.

Q: What clock speed does the OSA8212GAA6CR run at?

A: 2.20 GHz, fixed (no turbo boost).

Q: How much cache does the OSA8212GAA6CR have?

A: 2MB.

Q: What HyperTransport speed does the OSA8212GAA6CR support?

A: 1000 MHz.

James Everett

The OSA8212GAA6CR shows up on my bench almost exclusively as a replacement part, not a new build — someone has a Socket F 2P or 4P Opteron server still running production workloads and one CPU has failed. At 2.20 GHz dual-core with 1000 MHz HyperTransport, it's a known quantity for that generation of platform.

Technical Highlights:

• Socket F (LGA-1207): Mechanically and electrically specific to this Opteron generation — no adapter or workaround gets it into a different socket.
• 2MB cache / dual-core: On a 4-socket board that's 8 cores total system-wide, which was a meaningful consolidation play when this platform generation was current.
• 1000 MHz HyperTransport: Keeps inter-socket memory and I/O traffic coherent across multi-socket boards — check this against your chassis's HT speed ceiling if you're mixing steppings.

Deployment Considerations:

• Confirm BIOS/firmware CPU support list before ordering — legacy multi-socket boards were often validated against a narrow set of Opteron part numbers.
• 90nm process means more heat per core than later Opteron generations — factor this into rack thermal planning if you're populating multiple sockets.

Best fit: keeping an existing Socket F 2P/4P Opteron server alive past its refresh cycle without a full platform replacement, where a matching CPU swap is cheaper and faster than a chassis migration.
