AMD OS8431WJS6DGN Six-Core Socket F Server Processor

The AMD OS8431WJS6DGN is a 6-core Opteron 8431 server processor built on AMD's 45nm process, running at 2.4 GHz with a 2400 MHz HyperTransport link and 6MB of shared L3 cache. It's a Socket F (LGA-1207) part, which puts it squarely in 4-socket and 8-socket server board territory — the kind of multi-socket platform where core count per socket matters more than raw clock speed. If you're maintaining or expanding an existing Opteron 8000-series server rather than shopping for a new build, OS8431WJS6DGN is the part number to match against your board's supported CPU list before ordering.

Overview

Opteron 8431 sits in AMD's Product Series 8431 within the Opteron line, targeting multi-processor servers that need six physical cores per socket without pushing thermal design power past 75 watts. That 75W TDP is a meaningful number for anyone re-populating sockets on a 4P or 8P chassis — adding cores across multiple sockets multiplies heat output fast, and a 75W-per-socket ceiling helps keep aggregate system thermals inside what the chassis fans and airflow design were built to handle. The 55°C thermal specification tells you the ceiling the package is rated to run at, which matters when you're doing capacity planning in a densely populated rack rather than a single-socket tower.

Key Features

• 6-core design on Socket F: six physical cores per socket means a fully populated 4-socket board running OS8431WJS6DGN parts gives you 24 cores without touching the motherboard — the straightforward way to add processing headroom to an existing Opteron 8000-series deployment.
• 2.4 GHz core clock: a working clock speed for consolidated server workloads (virtualization hosts, database backends) where total core count matters more than single-thread speed.
• 6MB L3 cache: shared cache this size cuts down on main-memory round trips for multi-threaded workloads spread across six cores, which is where L3 pressure builds fastest.
• 2400 MHz HyperTransport (FSB): this is the interconnect speed between the processor and the rest of the platform (memory controller, I/O, other sockets) — a faster HT link matters more as you scale core and socket count, since more cores are contending for the same interconnect bandwidth.
• 45nm lithography: AMD's 45nm process on the Opteron 8431 is more power-efficient per core than the prior 65nm Opteron generation, part of how six cores land inside a 75W envelope.
• 75W thermal power (TDP): keeps per-socket heat output in check on multi-socket boards — important if you're upgrading an existing 8-socket chassis where the cooling system was designed around a specific TDP ceiling per socket.
• 55°C thermal specification: the rated maximum case temperature, a number worth checking against your rack's ambient and airflow conditions before populating multiple sockets with this part.
• Socket F (LGA-1207) package: confirms this CPU only fits Socket F server boards — check your motherboard's supported CPU list for OS8431WJS6DGN or the broader Opteron 8431 line before purchasing, since Socket F is not interchangeable with later Opteron socket generations.

Integration & Compatibility

OS8431WJS6DGN is built for Socket F (1207) server motherboards in the Opteron 8000-series family — typically 4P and 8P platforms used for virtualization consolidation and database hosting. Because these are legacy multi-socket boards, matching the exact stepping and BIOS support for the 8431 series is worth confirming with your board documentation before install, particularly in mixed-CPU multi-socket configurations. For teams standardizing spare or replacement parts across an existing fleet of Opteron 8000-series servers, this part number is a direct match for boards already running the 8431.

OS8431WJS6DGN is a straightforward six-core Socket F part, and the number that jumps out to me is the 75W TDP paired with six full cores at 2.4 GHz — AMD got real core-count density out of the 45nm process here without pushing thermals into territory that complicates an 8-socket chassis.

Technical Highlights:

• 6 cores / 2.4 GHz: six physical cores per socket at 2.4 GHz gives you real multi-threaded throughput on a fully populated 4P or 8P board without needing exotic cooling.
• 6MB L3 cache: shared cache of this size is sized to keep six cores fed without constant main-memory trips, which is where consolidated workloads bottleneck first.
• 2400 MHz HyperTransport: the interconnect speed matters more as socket count climbs — this is the link carrying memory and inter-socket traffic on a fully loaded 8P board.

Deployment Considerations:

• Confirm your Socket F (1207) motherboard's supported CPU list explicitly includes the Opteron 8431 stepping before ordering — Socket F server boards are picky about mixed-stepping multi-socket configurations.
• The 55°C thermal spec and 75W TDP are per-socket numbers — in a fully populated 8-socket chassis, aggregate heat output adds up fast, so check chassis airflow before scaling out.

This is the right part for keeping an existing Opteron 8000-series 4P/8P virtualization or database host running — not a fit for a new-build project where a current-generation platform makes more sense.
