AMD OS4274OFU8KGU 8-Core Server Processor

The OS4274OFU8KGU is an AMD Opteron 4274 HE server processor built around an eight-core design for multi-socket server platforms. This listing covers the base part identity confirmed in current sourcing records; detailed clock speed, cache, TDP, and socket compatibility figures are not included in the available product data, so they are omitted here rather than estimated.

Overview

AMD's Opteron 4000-series HE ('High Efficiency') processors were positioned for density-focused server deployments where per-socket power draw matters as much as core count. The OS4274OFU8KGU carries eight physical cores, which matters for buyers replacing or expanding existing Opteron 4200-series server nodes who need a like-for-like core count match rather than a platform redesign.

Key Features

• Eight-core design: gives the processor enough parallel execution capacity for multi-threaded server workloads — virtualization hosts, database nodes, or application servers — without moving to a higher-core-count part that may exceed the platform's socket power or thermal budget.
• Opteron 4200 HE series positioning: the 'HE' designation on this Opteron line targeted lower per-socket power draw versus standard parts in the same core-count class, relevant for rack environments where power and cooling headroom are already tight.
• Model-specific part number (OS4274OFU8KGU): AMD's OPN (Ordering Part Number) format encodes the exact SKU variant — confirm this exact string against your existing server's supported-CPU list before ordering, since Opteron 4200-series boards are frequently qualified for specific OPN suffixes only.

Integration & Compatibility

Because socket type, chipset compatibility, and supported motherboard list are not confirmed in current product data for the OS4274OFU8KGU, verify fit against your existing server platform's AMD Opteron 4200-series support list before purchasing — this is standard practice for legacy server CPU upgrades or replacements regardless of source.

The OS4274OFU8KGU is an eight-core Opteron 4274 HE — I get asked about these mostly from teams maintaining older AMD Opteron 4200-series server nodes rather than net-new builds. Available data on this specific part is thin, so I'm not going to guess at clock speed or TDP numbers I can't confirm.

Technical Highlights:

• 8 physical cores: matches the core count of the Opteron 4200 HE line, useful for a direct swap into a server already provisioned around that core density.
• HE ('High Efficiency') variant: this suffix on Opteron 4200-series parts denotes the lower-power bin within the family — worth confirming against your board's power delivery spec before install.
• OPN OS4274OFU8KGU: AMD's ordering part number pins down the exact SKU — cross-check it against your server vendor's qualified CPU list rather than assuming any 4274 HE part is interchangeable.

Deployment Considerations:

• Confirm your motherboard's BIOS/firmware supports this exact OPN before install — Opteron 4200-series boards are often picky about which suffix variants they'll boot.
• No published clock speed, cache, or TDP figures are available for this listing — get those from your server documentation or AMD's own records before planning a thermal/power budget around this part.

Best fit: a shop maintaining an existing AMD Opteron 4200-series server fleet who needs a matching eight-core replacement part rather than a platform refresh.
