AMD OS6320WKT8GHK 8-Core Opteron Server Processor

Overview

The AMD OS6320WKT8GHK is a retail-boxed Opteron 6320 processor built for Socket G34 server and workstation motherboards that need eight physical cores without stepping up to a dual-socket platform. This is the Opteron 6300 series (Piledriver-based, 32nm), positioned for infrastructure teams refreshing older G34 server nodes, running NVR/VMS back-end servers, or building out lab and lights-out management boxes where socket compatibility with existing G34 boards matters more than chasing the newest core architecture. At 2.80GHz base clock with a 6.4GT/s HyperTransport bus, the OS6320WKT8GHK is a straightforward drop-in for anyone maintaining an existing G34 fleet rather than migrating to a new platform.

Key Features

• 8-Core Design: Eight physical cores handle multi-threaded server workloads — virtualization hosts, recording server processes, and batch jobs — without relying on hyperthreading tricks to hit core counts.
• 2.80GHz Base Clock: Consistent clock speed across all eight cores keeps per-core throughput predictable for workloads that don't scale linearly with core count, like single-threaded management agents or legacy applications.
• 6.4GT/s HyperTransport Bus: Faster inter-core and memory-controller communication than earlier Opteron bus speeds, reducing latency in multi-socket G34 configurations where cores are coordinating across dies.
• 16MB L3 Cache: A larger shared cache pool cuts down on trips to main memory for frequently accessed data — meaningful on database or file-serving workloads where cache misses are the real bottleneck, not raw clock speed.
• Socket G34: Matches existing G34 server motherboards directly — the practical reason to buy this part is compatibility with a board you already have, not a platform upgrade.
• 32nm Manufacturing Process: A mature, well-understood process node for this processor generation, which keeps unit cost down relative to newer nodes — relevant if you're provisioning several nodes for a server room refresh on a budget.
• 115W TDP: A thermal envelope existing G34 server chassis and heatsinks were designed around, so you're not forced to requalify cooling when swapping this part into a compatible board.
• 2.15 lbs Shipping Weight: A retail-boxed unit light enough that ground shipping stays inexpensive for single-unit or small-batch orders.

Integration & Compatibility

The OS6320WKT8GHK requires a Socket G34 motherboard — check your board's supported CPU list before ordering, since G34 spans several Opteron generations with different BIOS/microcode requirements. It pairs naturally with G34 server motherboards running multi-socket configurations for virtualization or dense compute. If you're sourcing this to build out or repair a server handling video management or recording workloads, pair it with adequate server memory sized to your VMS or database software's per-core requirements, and confirm your chassis airflow is rated for a 115W part per socket in multi-CPU builds. For teams planning a broader server refresh rather than a single-socket swap, it's worth reviewing a VMS architecture guide to decide whether an aging G34 platform is still the right foundation going forward.

Frequently Asked Questions

Q: What socket does the OS6320WKT8GHK use?

A: Socket G34. Confirm your motherboard's supported CPU list before ordering, as G34 boards vary in which Opteron generations they support.

Q: What's the warranty on the OS6320WKT8GHK?

A: This unit ships with a 30-day return warranty.

Q: Is this a new or used processor?

A: This is sold as new, in retail box packaging.

Q: How many cores and what clock speed does the OS6320WKT8GHK run?

A: Eight physical cores at 2.80GHz base clock, with a 6.4GT/s HyperTransport bus and 16MB L3 cache.

Q: What's the TDP and does it need special cooling?

A: 115W TDP. It's designed to work with standard G34 server cooling solutions rated for that thermal envelope — no special cooling required beyond what your G34 chassis already supports.

Karl Wilson

The OS6320WKT8GHK crosses my desk most often as a replacement part rather than a new build — someone's got a G34 server down and needs an exact-fit eight-core Opteron 6320 at 2.80GHz to get it back online. That's the right way to think about this part.

Technical Highlights:

• 16MB L3 Cache: On this die, that's shared across all eight cores, which helps database and file-serving workloads that thrash cache more than they need raw clock cycles.
• 6.4GT/s HyperTransport: Keeps inter-die communication fast in dual-socket G34 boards, which is where this chip's eight cores really get exercised — single-socket builds won't see as much benefit from bus speed alone.
• 115W TDP: Matches what G34 chassis were originally speced for, so you're not fighting a cooling mismatch when you drop this into an existing rack unit.

Deployment Considerations:

• Verify your specific G34 motherboard's BIOS/microcode supports the 6300 series before ordering — not every G34 board covers the full Opteron generation range.
• This is a 30-day warranty part, not a multi-year manufacturer term — budget for that if you're stocking spares for a fleet rather than doing a one-off repair.

I'd point this at G34 server refresh or repair jobs — keeping an existing multi-socket virtualization host or recording server running — rather than a new platform build, since newer Opteron and EPYC generations have moved past G34 entirely.
