AMD OS6140WKT8EGO 8-Core Socket G34 Server Processor

Overview

The AMD OS6140WKT8EGO is an Opteron 6140 server processor built on the Socket G34 platform, running 8 cores at 2.6 GHz with a 115W TDP. This part number identifies the specific 6140 stepping validated for G34 dual-socket and quad-socket server boards still in service across data center refresh cycles, lab environments, and legacy virtualization hosts. If you're maintaining an existing G34 fleet rather than migrating to current-generation silicon, OS6140WKT8EGO is a direct drop-in replacement or expansion part rather than a platform gamble.

Key Features

• 8-core design: gives you real parallel thread handling for multi-VM hosts or batch workloads on G34 boards, without needing to source a 12- or 16-core Opteron variant that may run hotter or draw more from an aging power distribution setup.
• 2.6 GHz base clock: a middle-of-range clock speed for the Opteron 6100 series, balancing per-core throughput against the 115W thermal ceiling — relevant if your chassis airflow was sized for lower-wattage parts.
• Socket G34 package: confirms fitment on G34-only motherboards (common in dual/quad-socket AMD server platforms of this generation) — check your board's socket spec before ordering since G34 is not interchangeable with C32 or later Socket AM designs.
• 512 KB cache: per-core L2 cache sized for the Opteron 6100 architecture, adequate for general-purpose server workloads but a factor to weigh if you're running cache-sensitive database or virtualization workloads and comparing against higher-cache variants in the same family.
• 115W TDP: tells you exactly what your chassis cooling and power budget need to support per socket — in a dual-socket board that's 230W just from CPUs, a number worth checking against your PSU headroom before populating both sockets.
• OS6140WKT8EGO part number: the specific SKU to match against your motherboard's supported CPU list — G34 boards vary in which Opteron 6100-series steppings they support via BIOS/firmware revision, so confirm compatibility before purchase.

Integration & Compatibility

OS6140WKT8EGO is built for Socket G34 server motherboards — the platform used in AMD's Opteron 6100-series dual and quad-socket designs. Before deploying, verify your board's BIOS revision supports this specific stepping, since G34 boards shipped across multiple BIOS generations with varying Opteron 6100/6200 support lists. This part is a practical fit for extending the service life of existing G34 infrastructure, filling a failed-CPU RMA gap, or scaling out additional sockets on a quad-socket board without re-platforming the whole server. For teams standardizing hardware refresh plans, it's worth weighing the cost of sourcing legacy G34 parts against migrating the workload to a newer platform — a decision that depends heavily on how much life is left in the surrounding chassis, memory, and storage & memory investment already in place.

Frequently Asked Questions

Q: What socket does the AMD OS6140WKT8EGO use?

A: The OS6140WKT8EGO is built for Socket G34, used on AMD Opteron 6100-series dual and quad-socket server motherboards.

Q: How many cores and what clock speed does the OS6140WKT8EGO run?

A: It's an 8-core processor running at a 2.6 GHz base clock.

Q: What is the TDP of the OS6140WKT8EGO, and what does that mean for cooling?

A: The OS6140WKT8EGO has a 115W TDP per socket, so a dual-socket board needs cooling and power delivery sized for 230W from CPUs alone.

Q: How much cache does the OS6140WKT8EGO have?

A: It carries 512 KB of cache per the manufacturer specification.

Q: Is the OS6140WKT8EGO new or refurbished?

A: This part is offered factory-new through channel-direct sourcing, with no grey-market or parallel-import inventory.

The OS6140WKT8EGO lands in that awkward but common spot: a G34 fleet that's still doing real work and doesn't need a full re-platform yet. This 8-core Opteron 6140 running at 2.6 GHz is a known quantity for anyone who's kept a dual-socket G34 box alive past its original refresh date.

Technical Highlights:

• 8 cores @ 2.6 GHz: enough parallel headroom for multiple VMs or batch jobs on a G34 host without pushing into higher-core Opteron variants that run hotter.
• 115W TDP: per-socket draw you can plan against directly — populate both sockets on a dual-socket board and you're budgeting 230W from CPU alone, before drives, memory, or expansion cards.
• 512 KB cache, Socket G34: matches the Opteron 6100-series platform spec exactly, which matters because G34 boards are picky about which steppings their BIOS revision actually supports.

Deployment Considerations:

• Confirm your motherboard's BIOS CPU support list before ordering — G34 boards spanned multiple BIOS generations and not every board recognizes every Opteron 6100/6200 stepping out of the box.
• Watch out for thermal headroom in older chassis: 115W per socket adds up fast in a quad-socket configuration, and airflow designed years ago may not have margin for a fully populated board.

This is the right call for a data center team stretching the service life of an existing dual or quad-socket G34 deployment — a failed-CPU RMA swap or a socket-population expansion — not for anyone speccing a new build from scratch.
