AMD OS6328WKT8GHKWOF 8-Core Opteron 6328 Server Processor

Overview

The AMD OS6328WKT8GHKWOF is an 8-core Opteron 6328 server processor built for Socket G34 LGA-1944 platforms, clocked at 3.20 GHz with a 16 MB cache and a 115W thermal design power envelope. It's a drop-in option for teams maintaining existing G34 multi-socket server infrastructure — think video management servers, NVR back-ends, or general compute nodes in a security operations center — where a board-level swap or spare-parts replacement is more practical than a full platform refresh. The OS6328WKT8GHKWOF is built on AMD's 32nm process, a mature node that keeps unit cost down relative to newer silicon while still delivering solid multi-threaded throughput for parallelized workloads.

Key Features

• 8-Core Design: Eight physical cores handle multi-threaded workloads — video analytics pipelines, database queries, or virtualized workloads spread across several VMs — without funneling everything through a smaller core count and hitting a throughput ceiling.
• 3.20 GHz Clock Speed: A straightforward, consistent clock across all cores means predictable per-thread performance for applications that don't auto-scale well with core count, such as single-threaded recording services.
• 16 MB Cache: A larger on-die cache cuts down on trips to main memory, which matters most in database-heavy or multi-VM environments where cache misses translate directly into latency spikes.
• Socket G34 LGA-1944: This is the deciding factor before you buy — the OS6328WKT8GHKWOF only fits G34 motherboards and chassis already provisioned for that socket. Confirm your board's socket type before ordering; there's no cross-compatibility with newer AMD server sockets.
• 115W TDP: A moderate thermal envelope for an 8-core part of this era, which keeps cooling requirements manageable in a 1U or 2U chassis already designed around G34's thermal profile, without needing to re-engineer airflow.
• 32nm Process Technology: An established, high-yield fabrication node. For buyers replacing a failed CPU in an existing deployment, that maturity generally means more consistent part-to-part behavior versus chasing a newer, less proven stepping.

Integration & Compatibility

Compatibility here is binary: the OS6328WKT8GHKWOF requires a Socket G34 LGA-1944 motherboard, and it's commonly deployed in dual-socket or quad-socket Opteron 6300-series server boards. If you're standardizing a fleet of G34 servers or need a matched pair for a dual-socket board, confirm your existing CPUs' stepping and BIOS revision before mixing processors — mismatched steppings across sockets can cause boot or stability issues on some board vendors' firmware. This part is best positioned as a maintenance or expansion component for sites that already run G34-based infrastructure rather than as a new-build recommendation, since G34 platforms are a legacy socket generation at this point.

Frequently Asked Questions

A: Socket G34 LGA-1944. It is not compatible with other AMD server sockets.

Q: How many cores and what clock speed does the OS6328WKT8GHKWOF run?

A: Eight cores at 3.20 GHz.

Q: What is the thermal design power (TDP) of the OS6328WKT8GHKWOF?

A: 115W.

Q: How much cache does the OS6328WKT8GHKWOF have?

A: 16 MB.

Q: Can the OS6328WKT8GHKWOF be used in a single-socket board?

A: It is compatible with any Socket G34 LGA-1944 board, including single-socket configurations, provided the board supports the Opteron 6300 series.

Jerry Tildsen

The OS6328WKT8GHKWOF crosses my bench most often as a replacement part, not a new build — if you're already running Socket G34 Opteron 6300-series servers, this 8-core, 3.20 GHz part is the straightforward way to keep a chassis alive without a platform swap.

Technical Highlights:

• 8 Cores @ 3.20 GHz: Consistent per-core clock across all eight cores keeps mixed single-thread and multi-thread workloads predictable — useful when a box is running both a recording service and background analytics jobs.
• 16 MB Cache: Reduces memory round-trips on cache-sensitive workloads like database lookups, which pays off in multi-VM or multi-service deployments sharing the same socket.
• 115W TDP: Fits within the thermal budget most G34 1U/2U chassis were already designed around, so you're not fighting cooling headroom on a straight swap.

Deployment Considerations:

• Verify your motherboard's BIOS revision supports the Opteron 6328 stepping before installing — G34 boards from different vendors had varying microcode support across the 6300 series lifecycle.
• This is a legacy socket. If you're spec'ing a new server rather than repairing an existing one, a current-generation platform will outperform this part on every axis except acquisition cost.

Best fit: a dual-socket G34 video management or database server where one CPU has failed and you need a matched part to restore the pair, not a greenfield deployment.
