AMD OS4238WLU6KGUWOF Hexa-Core Server Processor

Overview

The AMD OS4238WLU6KGUWOF is an Opteron 4200-series hexa-core processor built for Socket C32 server platforms running virtualization, database, and general-purpose enterprise workloads. Packaged as a retail unit rather than a bulk OEM tray, this factory-new part suits single-unit server builds, lab environments, and planned replacement stock for existing Opteron 4200 deployments where matching an existing socket and platform generation matters more than chasing the newest core architecture. With six physical cores at a 3.30 GHz base clock and a documented 8 MB L3 cache, this processor targets multi-threaded server tasks — web hosting, file services, and mid-tier virtualization — where core count and cache depth affect throughput more than single-thread peak speed.

Key Features

• Hexa-Core Design (6 Core): Six physical cores let the OS4238WLU6KGUWOF handle multiple concurrent server processes or VM instances without the scheduling contention you get on dual- or quad-core parts — relevant if you're consolidating several lighter workloads onto one box.
• 3.30 GHz Base Clock: A 3.30 GHz base frequency keeps per-thread performance competitive for the Opteron 4200 generation, useful for workloads that mix moderate parallelism with latency-sensitive request handling.
• 3.50 GHz Max Turbo: The processor steps up to 3.50 GHz under Turbo CORE conditions, giving short bursts of extra headroom for spiky workloads without changing the thermal envelope at idle.
• 8 MB L3 Cache: A shared 8 MB L3 cache reduces main-memory round trips across the six cores — directly relevant for database and virtualization workloads where cache misses are a common bottleneck.
• 1000 KB L2 Cache: Combined with the L3, the 1 MB L2 allocation gives each core a meaningful working set before falling back to system memory, smoothing out performance on mixed I/O and compute tasks.
• 48 KB L1 Cache: Standard per-core L1 sizing keeps the fastest cache tier close to execution units for the tightest instruction/data loops.
• 64-bit Processing: Full 64-bit support is required for any modern 64-bit server OS and for addressing memory beyond legacy 32-bit limits — a baseline requirement rather than a differentiator at this point, but worth confirming against your existing platform.
• 32nm Process Technology: The 32nm die process is what allows six cores and 9 MB of combined cache to fit inside a 95W power envelope — important context when comparing this part against older, less efficient Opteron steppings.
• Socket C32 OLGA-1207: This processor drops into Socket C32 OLGA-1207 boards only — it will not fit AM3, G34, or later Opteron sockets, so confirm your motherboard's socket before ordering a replacement or upgrade part.
• 95W TDP: A 95W thermal design power figure lets you plan cooling and power budgets for multi-socket chassis without over-provisioning — meaningful when you're filling out a rack with several units on the same PDU circuit.
• 158.9°F (70.5°C) Thermal Specification: The documented maximum operating temperature of 70.5°C gives you a hard ceiling for airflow and case-temperature planning in dense server rooms.

Integration & Compatibility

The OS4238WLU6KGUWOF is built specifically for Socket C32 OLGA-1207 motherboards used in Opteron 4200-series server platforms — check your board's supported CPU list before purchasing, since socket compatibility does not extend to Opteron 6000-series (Socket G34) or later AMD server platforms. This is sourced as a factory-new, genuine retail-packaged unit — no grey-market, no parallel imports — which matters for server hardware where a mismatched or counterfeit stepping can cause platform instability. If you're maintaining an existing fleet of Opteron 4200 servers, this part lets you standardize on a known-good processor generation rather than mixing steppings across your rack.

Frequently Asked Questions

Q: What socket does the AMD OS4238WLU6KGUWOF use?

A: It uses Socket C32 OLGA-1207, the same socket used across the AMD Opteron 4200 series. It is not compatible with Socket G34 or later AMD server sockets.

Q: How many cores and what clock speed does the OS4238WLU6KGUWOF run at?

A: It is a hexa-core (6-core) processor with a 3.30 GHz base clock and up to 3.50 GHz under Turbo CORE.

Q: How much cache does this processor have?

A: It carries 48 KB L1, 1000 KB (1 MB) L2, and 8 MB L3 cache.

Q: What is the thermal design power (TDP) of the OS4238WLU6KGUWOF?

A: 95W, with a documented maximum operating temperature of 70.5°C (158.9°F).

Q: Is this a retail or OEM/tray processor?

A: This is a retail-packaged unit, factory-new and genuine.

The OS4238WLU6KGUWOF is a straightforward Socket C32 replacement part — six cores at 3.30 GHz base with an 8 MB L3 cache, aimed squarely at shops still running Opteron 4200-series server boards. If you're standardizing a rack on this generation, this is the part number to keep on hand.

Technical Highlights:

• 6 cores @ 3.30 GHz (3.50 GHz turbo): Enough parallelism for several concurrent VM instances or service processes without relying purely on clock speed.
• 8 MB L3 / 1000 KB L2 cache: A deep cache hierarchy for a chip this generation, which helps cache-sensitive workloads like database queries avoid main-memory latency.
• 95W TDP at 32nm: Keeps thermal load predictable in multi-unit chassis — plan airflow around the documented 70.5°C max operating spec, not just the TDP number.

Deployment Considerations:

• Confirm your motherboard's BIOS supports the 4238 stepping specifically — Socket C32 boards shipped across several Opteron 4200 revisions and not all firmware versions list every part.
• This is Socket C32 OLGA-1207 only — it will not physically fit Opteron 6000-series G34 boards, a common mix-up when sourcing replacement CPUs for older fleets.

Reach for the OS4238WLU6KGUWOF when you're replacing a failed or end-of-life processor in an existing Opteron 4200 server rack and need a factory-new, genuine unit that matches your current platform generation exactly — not for new-build platforms where a current-generation socket makes more sense.
