AMD OS4284WLU8KGU 8-Core Server Processor

Overview

The AMD OS4284WLU8KGU is an Opteron 4284 server processor built for Socket C32 platforms that need dense multi-threaded throughput without moving up to a dual-socket chassis. It packs 8 physical cores running at a fixed 3.00 GHz, backed by 8MB of cache and a 95W thermal design power envelope — a spec set aimed at single-socket 1U/2U servers handling virtualization, database, or network-edge workloads where core count matters more than single-thread burst speed. If you're refreshing or expanding a fleet of C32-socket servers, or sourcing a spare/replacement CPU for an existing deployment, the OS4284WLU8KGU is a straightforward drop-in built on AMD's 32nm process technology.

Key Features

• 8-Core Design: Eight physical cores let a single socket handle parallel workloads — multiple VMs, concurrent database queries, or multi-threaded application servers — that would otherwise require a second CPU socket, simplifying motherboard choice and reducing per-socket licensing costs on software billed by socket.
• 3.00 GHz Clock Speed: A flat 3.00 GHz across all eight cores gives predictable per-core performance for workloads that scale with thread count rather than depending on turbo spikes — useful for consistent capacity planning in virtualized environments.
• 32nm Process Technology: The 32nm die shrink (versus older 45nm Opteron parts) improves performance-per-watt, which is part of why this 8-core part holds to a 95W TDP instead of the higher power draw seen in earlier-generation designs.
• 8MB Cache Memory: A larger on-die cache reduces trips to main memory for frequently accessed data, which matters most in database and virtualization workloads where cache misses translate directly into latency.
• 95W Thermal Design Power: A 95W TDP keeps this processor within the thermal and power budget of standard single-socket server cooling and PSU designs — no need for oversized heatsinks or upgraded power delivery to accommodate it.
• Socket C32 OLGA-1207: Built specifically for Socket C32 OLGA-1207 motherboards, the standard single-socket Opteron 4000-series platform — confirm your board's socket type before ordering, since Opteron sockets (C32 vs G34) are not interchangeable.
• 6400 MHz HyperTransport: The 6400 MHz HyperTransport link speed governs how fast the CPU communicates with chipset and I/O controllers on the board — a factor in overall platform responsiveness for I/O-heavy workloads like storage controllers and NICs.

Integration & Compatibility

The OS4284WLU8KGU is built for Socket C32 OLGA-1207 motherboards in the AMD Opteron 4000-series server family — the platform commonly used in single-socket rack servers for hosting, virtualization, and network infrastructure roles. Before ordering, verify your motherboard's BIOS supports this specific Opteron 4284 stepping, since server board vendors typically publish CPU support matrices tied to BIOS revision. When planning a build or refresh around this processor, pair it with server memory and storage sized to the workload — reviewing a server memory and storage lineup alongside the CPU helps avoid bottlenecking eight cores with insufficient RAM bandwidth. For teams standardizing on AMD server silicon across a fleet, browsing the broader server processor selection helps line up compatible steppings and TDP classes for mixed-generation racks.

Deployment Notes

Because this is a bare OEM processor (OS4284WLU8KGU part number), it ships without a bundled heatsink or fan — plan to reuse your existing Socket C32 cooling solution or source one rated for a 95W TDP separately. If you're sourcing this as a replacement part for an existing production server, cross-check the exact Opteron 4284 revision your motherboard's BIOS was validated against, since Opteron 4000-series boards from different vendors sometimes lock support to specific CPU steppings. For fleets running mixed AMD and Intel-generation servers, consult a server configuration and design resource to confirm CPU, chipset, and memory compatibility before committing to a bulk order.

Frequently Asked Questions

Q: What socket does the AMD OS4284WLU8KGU use?

A: The OS4284WLU8KGU uses Socket C32 OLGA-1207, the standard socket for AMD's Opteron 4000-series single-socket server platform.

Q: How many cores and what clock speed does the OS4284WLU8KGU run?

A: It's an 8-core processor running at a fixed 3.00 GHz per core.

Q: What is the TDP of the OS4284WLU8KGU?

A: 95W thermal design power, within standard single-socket server cooling and PSU budgets.

Q: Does the OS4284WLU8KGU include a heatsink or fan?

A: No — this is a bare OEM processor. Cooling must be sourced separately or reused from an existing Socket C32 build.

Q: What is the HyperTransport speed on the OS4284WLU8KGU?

A: 6400 MHz, governing communication speed between the CPU and platform chipset/I-O controllers.

The OS4284WLU8KGU is one of the more straightforward Socket C32 refresh parts I spec for single-socket Opteron 4000-series builds — 8 cores at a flat 3.00 GHz with a 95W TDP that doesn't force a cooling upgrade on existing chassis.

Technical Highlights:

• 8-Core / 3.00 GHz: Eight cores at a consistent 3.00 GHz gives predictable per-thread performance across virtualization or multi-threaded workloads without relying on turbo behavior.
• 8MB Cache: A sizable on-die cache cuts main-memory round trips, which shows up most in database and VM-dense workloads sensitive to cache misses.
• 95W TDP on 32nm: The 32nm process keeps an 8-core part inside a 95W envelope, fitting stock single-socket server cooling instead of demanding an upgraded heatsink or PSU.

Deployment Considerations:

• This is a bare OEM processor with no bundled heatsink/fan — reuse your existing Socket C32 cooling or source one rated for 95W separately.
• Socket C32 OLGA-1207 is not interchangeable with Opteron's G34 socket — verify your motherboard's exact socket and BIOS support for the Opteron 4284 stepping before ordering.

This part fits a single-socket Opteron 4000-series server that needs an 8-core density bump — a virtualization host or database node running on existing C32 infrastructure where a second socket isn't justified.
