AMD OS4226WLU6KGU 6-Core Server Processor

The AMD OS4226WLU6KGU is a six-core Opteron 4226 server processor built for Socket C32 platforms, running a base clock of 2.7 GHz with 8 MB of cache. It's a drop-in upgrade or replacement part for existing Opteron 4000-series server and workstation deployments rather than a new-platform choice — the socket and processor family are fixed by your existing motherboard, so confirm compatibility before ordering.

Overview

OS4226WLU6KGU is the exact ordering part number for this Opteron 4226 unit. It targets refresh and repair scenarios: replacing a failed CPU in a running server, adding a matched processor to a dual-socket board, or keeping an older Socket C32 platform in service without a full server replacement.

Key Features

• 2.7 GHz base frequency: gives existing Socket C32 servers a defined clock-speed baseline for per-core workloads — useful when matching or replacing a processor in a system where consistent core speed across sockets matters for stability.
• Six-core design: spreads virtualization, database, or multi-threaded application loads across more execution cores than entry-level Opteron variants, which matters if the host is already running multiple VMs or services.
• 8 MB cache: larger on-die cache reduces trips to main memory for frequently accessed data, which helps keep latency down on I/O-heavy or database workloads typical of the servers this processor was built for.
• Socket C32 package: this is a fixed physical and electrical fit — it only installs in motherboards built for the C32 socket, so it's a match for existing infrastructure rather than a new build.
• Opteron 4000-series family: keeps a matched-processor pair or an existing fleet standard consistent, which avoids the BIOS and NUMA-balancing headaches that come with mixing processor steppings across sockets.

Integration & Compatibility

OS4226WLU6KGU installs only in server or workstation boards with a Socket C32 CPU socket. Verify your motherboard's supported-processor list before ordering, and if the target system is dual-socket, match stepping and frequency with the existing installed processor to avoid instability. This part is not a fit for any other AMD socket generation.

Frequently Asked Questions

Q: How much cache does the OS4226WLU6KGU have?

A: 8 MB of processor cache.

Q: Is the OS4226WLU6KGU part of the Opteron family?

A: Yes, it is an AMD Opteron 4226 processor.

Jerry Tildsen

OS4226WLU6KGU is a straightforward part to spec once you know your socket: it's a Socket C32 six-core Opteron running 2.7 GHz with 8 MB of cache, nothing more exotic than that.

Technical Highlights:

• 2.7 GHz / 6 cores: a defined, repeatable clock baseline for matching against an existing installed processor on dual-socket boards.
• 8 MB cache: larger shared cache reduces memory round-trips on I/O-bound server workloads.
• Socket C32 package: fixed physical fit — confirm your board's supported CPU list before ordering, there's no adapter path to other sockets.

Deployment Considerations:

• On dual-socket boards, match stepping and frequency to the currently installed processor to avoid BIOS or NUMA-balancing issues.
• Socket C32 is an older server platform — this part fits refresh and repair jobs on existing hardware, not new-build specs.

Right fit for keeping an existing Socket C32 dual-processor server running at full core count after a CPU failure, or for standardizing a small fleet of older Opteron-based servers on a matched processor spec.
