AMD OS8423WJS6DGN 6-Core Opteron Server Processor

The AMD OS8423WJS6DGN is a 6-core Opteron 8423 processor built for Socket F LGA-1207 multi-socket server platforms where you need to add or replace compute density without a full board swap. Running at 2GHz with 6MB of L3 cache and a 75W TDP, this part fits legacy 4P/8P Opteron server refreshes, lab test benches, and spare-parts inventory for fleets still running Socket F hardware. It ships as a genuine retail box unit with a 30-day warranty.

Overview

This is a drop-in replacement or upgrade path for administrators maintaining older AMD Opteron 8000-series server infrastructure. The Socket F LGA-1207 form factor was widely deployed across 4-socket and 8-socket rackmount servers, and parts like the OS8423WJS6DGN remain relevant for organizations extending the service life of that hardware rather than forklift-upgrading an entire chassis. Sourcing genuine, factory-new stock matters here — grey-market Socket F chips are common in the secondary market, and a mismatched or counterfeit part in a multi-socket board can cause boot failures or instability across the whole system.

Key Features

• 6-Core Design: Six physical cores at the socket give multi-socket boards a meaningful step up in parallel thread handling over quad-core Opteron 8000-series parts, useful for virtualization hosts or batch-processing workloads still running on this platform.
• 2GHz Core Clock: A conservative clock speed keeps thermal output predictable across dense 4P/8P chassis where multiple CPUs share tight airflow — important when you're not trying to push single-thread performance, just keep aggregate throughput up.
• 6MB L3 Cache: Shared L3 cache reduces main-memory round trips for multi-threaded server workloads, which matters more on this platform than raw clock speed given the core count per socket.
• 75W TDP: A lower thermal ceiling than the higher-clocked Opteron 8000-series parts, which matters directly in 8-socket chassis where cumulative CPU heat load determines whether the existing heatsink and airflow design stays adequate without a cooling redesign.
• Socket F LGA-1207: Confirms physical and electrical compatibility with existing Socket F server motherboards — check your board's supported CPU list before ordering, since Socket F spans several Opteron generations with different BIOS microcode requirements.
• 2.05 lbs Shipping Weight: Reflects the retail packaging weight; ground shipping up to 10 lbs is free within the United States, so a single-unit order like this ships at no extra freight cost.

Integration & Compatibility

The OS8423WJS6DGN is electrically and mechanically compatible only with Socket F LGA-1207 motherboards that support the Opteron 8423 in their CPU support list — confirm your board vendor's BIOS revision requirements before installing, since older BIOS versions on Socket F boards sometimes need a firmware update to recognize later Opteron steppings. This part is intended for server CPU replacement, upgrade, or spares stock rather than new system builds, given the age of the Socket F platform. If you're planning a broader refresh instead of a single-socket swap, review a CPU selection guide before committing budget to legacy socket hardware. For servers pulling this CPU out of service, compatible server memory and server motherboards from the same generation are worth checking against your existing chassis specs. Buyers evaluating the broader AMD processor catalog should weigh whether a platform-level upgrade makes more sense than continuing to source Socket F parts long-term.

The OS8423WJS6DGN is one of those parts that only makes sense once you already own the platform it's built for — a Socket F LGA-1207 board expecting an Opteron 8423 isn't taking anything else. If you're staring at an empty CPU socket in an aging 4P or 8P chassis, this is the part number to match, not a substitute.

Technical Highlights:

• 6-Core / 2GHz: Six cores at a conservative 2GHz clock is built for aggregate throughput across many threads rather than single-thread speed — the right tradeoff for the virtualization and batch workloads this platform generation was aimed at.
• 75W TDP: Meaningfully lower heat output than higher-binned Opteron 8000-series parts, which matters when you're populating 4 or 8 sockets in one chassis and the shared airflow budget is already tight.
• 6MB L3 Cache: Shared cache of this size helps offset the modest clock speed on multi-threaded server tasks by cutting down trips to main memory.

Deployment Considerations:

• Verify your motherboard's BIOS supports the Opteron 8423 stepping before installing — Socket F spans multiple Opteron generations and older BIOS revisions sometimes need a firmware update first.
• This is a single-socket-population part, not a full system — it only closes the gap on boards already built for Socket F. It won't help if you're trying to move to a current-generation platform.

Reach for the OS8423WJS6DGN when you're keeping an existing Socket F 4P/8P Opteron server running past its original refresh cycle — filling a dead socket, adding compute to an underpopulated chassis, or stocking a spare for a fleet of identical boards — rather than as a building block for a new deployment.
