AMD OS6276WKTGGGU 16-Core Opteron 6276 Server CPU

The OS6276WKTGGGU is a 16-core AMD Opteron 6276 processor clocked at 2.30GHz, built for the G34 socket used across a range of dual- and quad-socket rack and blade servers. If you're maintaining or expanding an existing Opteron 6200-series server fleet, this part fills a specific niche: adding compute density to a platform that's often past new-unit availability, without a full server refresh.

Overview

This is a commercial-grade server-class processor, not a consumer or embedded part — the G34 socket and 16-core Bulldozer-architecture design place it squarely in dual-socket rack servers and blade nodes from the early-2010s Opteron 6200 generation. OS6276WKTGGGU is the exact AMD part number stamped on the CPU's integrated heat spreader, which matters when you're matching a replacement or expansion part against what's already installed in a chassis.

Key Features

• 16-core count: gives you more parallel threads per socket than earlier Opteron 61xx-series parts, useful for consolidating virtualized workloads onto fewer physical nodes when you're stretching the life of an existing server platform.
• 2.30GHz base clock: a steady clock speed for sustained multi-threaded loads like batch processing or VM hosts, rather than single-thread burst work.
• G34 socket: drop-in compatible only with motherboards and servers built for the G34 socket footprint — confirm your chassis supports this socket before ordering, since it is not interchangeable with C32 or newer Opteron sockets.

Integration & Compatibility

Because this is a used/pulled server component rather than a new retail part, plan for it as a match to an existing G34-socket deployment (dual-socket Opteron 6200-series servers) rather than a new build. Pair it with a matched second CPU if populating a dual-socket board, and verify your server vendor's supported CPU list before installing.

Frequently Asked Questions

Q: What socket does the OS6276WKTGGGU use?

A: It uses the G34 socket, standard across the AMD Opteron 6200 series.

Q: How many cores and what clock speed does this CPU run?

A: 16 cores at a 2.30GHz base clock.

Q: Is the OS6276WKTGGGU new or refurbished?

A: This listing is for a refurbished/pulled server processor rather than new factory stock.

Marty Allison

The OS6276WKTGGGU is a 16-core Opteron 6276 running at 2.30GHz on the G34 socket — I see this part requested most often by teams keeping an aging dual-socket Opteron 6200-series server alive rather than replacing the whole chassis.

Technical Highlights:

• 16-core count: more parallel threads per socket than earlier 61xx-series Opterons, which helps when you're consolidating VM workloads onto fewer physical nodes.
• 2.30GHz base clock: consistent enough for sustained multi-threaded server workloads rather than latency-sensitive single-thread tasks.
• G34 socket: fixed compatibility — this only drops into G34 boards, so check your server's supported CPU list first.

Deployment Considerations:

• If you're populating a dual-socket board, match this with a second identical OS6276WKTGGGU rather than mixing steppings.
• This is a pulled/refurbished part, not new factory stock — treat it as a fleet-maintenance component rather than a new-build spec.

Best fit: extending the service life of an existing dual-socket G34 Opteron 6200-series server that's out of new-part support, where a same-generation core/clock match matters more than raw new-platform performance.
