AMD OS6376WKTGGHK 16-Core Server Processor

Overview

The AMD OS6376WKTGGHK is a 16-core Opteron 6376 server processor built for multi-socket rack and blade servers running virtualization-heavy or multi-threaded workloads — think hypervisor hosts, database nodes, and render or transcode farms where core count matters more than single-thread clock speed. This part is factory-new, sourced through channel-direct sourcing with no grey-market or parallel imports, and drops into existing G34-socket Opteron 6300-series server boards without a platform redesign. If you're maintaining or expanding a fleet already running Opteron 6300-series silicon, the OS6376WKTGGHK is a straightforward like-for-like or capacity-add component.

Key Features

• 16-Core Design: Sixteen physical cores let you assign more concurrent VMs or threads per socket without splitting workloads across additional physical servers — useful when rack space or per-server licensing is the constraint, not raw compute.
• 2.3GHz Base Clock: A 2.3GHz clock keeps sustained multi-threaded throughput predictable under full core load, which matters more for batch and virtualization workloads than burst single-thread tasks.
• 16MB Cache Memory: A 16MB cache pool reduces main-memory round trips on data sets that don't fit in per-core cache, which shows up as steadier throughput on database and virtualization workloads with high memory churn.
• 115-Watt TDP: A 115W thermal envelope is a known quantity for planning per-socket cooling and power budgets in dual- and quad-socket chassis already engineered around Opteron 6300-series TDP limits.
• G34 Socket Compatibility: Built for the same physical and electrical socket as the rest of the Opteron 6300 series, so it installs into existing multi-socket boards without a motherboard swap — the practical reason to buy this part instead of a newer platform.
• AMD Manufacturer Part Number OS6376WKTGGHK: The OPN on the heat spreader is how you verify you received the exact stepping and spec your server board's BIOS/AGESA support list expects — check it against your board vendor's supported CPU list before ordering at scale.

Integration & Compatibility

The OS6376WKTGGHK is intended for multi-socket Opteron 6300-series server and blade platforms. Before deploying, confirm your motherboard's BIOS revision is on the supported CPU list for the 6376 stepping — Opteron 6300-series boards frequently require a specific AGESA/BIOS version to recognize later steppings correctly, and mismatched sockets in a multi-CPU board should be avoided. Pair with server memory rated for the platform's channel configuration, and size cooling to the full 115W TDP per socket, especially in dense multi-socket chassis. For teams standardizing a fleet on this platform, sourcing compatible OS6376WKTGGHK units in volume keeps stepping and firmware behavior consistent across nodes.

Frequently Asked Questions

Q: Is the OS6376WKTGGHK new or refurbished?

A: The OS6376WKTGGHK is factory-new, genuine AMD silicon — not refurbished or remanufactured.

Q: What socket does the OS6376WKTGGHK use?

A: It uses the AMD G34 socket, consistent with the rest of the Opteron 6300 series, so it fits existing G34 multi-socket server boards.

Q: How many cores and what clock speed does the OS6376WKTGGHK run?

A: Sixteen cores at a 2.3GHz base clock, with 16MB of cache memory.

Q: What's the TDP on the OS6376WKTGGHK, and what does that mean for cooling?

A: 115 watts. Cooling and power delivery should be sized per socket to this figure, particularly in dual- or quad-socket configurations.

Q: What warranty comes with the OS6376WKTGGHK?

A: This unit carries a 30-day warranty.

Ted Perry

The OS6376WKTGGHK is a 16-core Opteron 6376 running at 2.3GHz, and the core count is really the whole story here — this is a part for spreading VM density or parallel workloads across sockets, not for chasing single-thread speed.

Technical Highlights:

• 16 Cores / 2.3GHz: sixteen physical cores at 2.3GHz gives you real headroom for consolidating VMs onto fewer physical hosts in a G34 dual- or quad-socket chassis.
• 16MB Cache: a 16MB cache pool helps absorb memory-access patterns typical of virtualization and database workloads without constant round trips to system RAM.
• 115W TDP: a fixed, well-documented thermal envelope — plan cooling and PSU headroom per socket against this number, not a guess.

Deployment Considerations:

• Confirm your server board's BIOS/AGESA revision is on the supported list for the 6376 stepping before installing — Opteron 6300-series boards can be picky about firmware versions with later steppings.
• This unit carries only a 30-day warranty, so validate the part on arrival — burn it in before committing it to a production node.

Good fit for teams keeping an existing Opteron 6300-series fleet running — replacing a failed socket or adding a matched node — rather than for a new platform build.
