AMD EPYC 7543 32-Core Server Processor

The AMD EPYC 7543 is a 32-core server processor built on 7 nm technology with a base frequency of 2.8 GHz and a max turbo of 3.7 GHz. It features 256 MB of L3 cache and supports 64 threads for parallel workloads. The Socket SP3 CPU targets high-density compute and virtualisation platforms.

Suits multi-threaded workloads

This CPU suits deployments that need 128 PCIe 4.0 lanes and eight-channel DDR4 3200 memory bandwidth. It is not for builds that require integrated graphics or consumer socket compatibility. Buyers needing lower power envelopes or single-thread optimisation should evaluate alternatives.

Processor-only package requires separate cooling

The unit ships without a cooling device, so a compatible SP3 heatsink rated for 225 W TDP must be sourced separately. Installation follows standard server board mounting procedures. Ensure the chassis airflow meets the thermal design power before deployment.

Questions sur cet article

What motherboard socket is required for the EPYC 7543?

The processor fits a Socket SP3 motherboard designed for AMD EPYC 7003 series CPUs.

Will my existing DDR4-3200 modules run at rated speed with this 8-channel memory controller?

Yes, the integrated memory controller supports DDR4 3200 across all eight channels when populated correctly.

How can I verify the 32 cores and 64 threads are recognised after installation?

Check the OS task manager or run lscpu; both should report 32 cores, 64 threads and a 2.8 GHz base frequency.
