Sixteen Zen 5 cores for a compact single-socket server platform
16 cores / 32 threads3.0–5.4GHz64MB L365W default TDP
The AMD EPYC 4545P is a 16-core, 32-thread server processor from the EPYC 4005 family. It combines a 3.0GHz base clock and boost up to 5.4GHz with 64MB L3 cache and a 65W default TDP. Built for a single-socket AM5 server platform, it supports two DDR5 memory channels and PCIe 5.0 connectivity. This listing is the tray part 100-000001764.
Best For: Validated small-business, branch-office and hosting servers that need parallel CPU resources in a single-socket design.
Before you order: Check the server motherboard’s explicit EPYC 4545P CPU support list and required BIOS version. An AM5 socket alone does not guarantee compatibility. This tray CPU requires separate suitable cooling, supported DDR5 memory and the rest of a complete server platform. Boost speed and memory operation depend on workload and system configuration.
What's in the Box
- AMD EPYC 4545P processor, tray/OEM part 100-000001764.
- No retail boxed presentation or included cooler is claimed; plan a suitable cooling solution separately.
What It Means in Practice
- Use the 16 cores and 32 threads for compatible concurrent server applications or hosted services.
- Select server-vendor-approved DDR5 ECC memory and follow its population and speed guidance.
- Plan storage and networking expansion against the actual motherboard PCIe slot and lane allocation.
- Confirm firmware, operating-system and security-feature support before deploying business applications.
What Will Not Work
- CPU only; motherboard, memory, storage, operating system and cooling are separate.
- Single-socket 1P model; not a dual-socket processor.
- Up to 5.4GHz is maximum boost, not a guaranteed all-core sustained clock.
- Infinity Guard features depend on processor series and OEM enablement. AMD states SEV is not supported by EPYC 4004/4005.
Key Features
Parallel server capacity
16 Zen 5 cores and 32 threads support compatible concurrent workloads.
65W design target
The default TDP suits platform planning; actual system consumption depends on workload and other components.
DDR5 and PCIe 5.0
Two memory channels and 28 CPU PCIe lanes provide the platform foundation.
Server platform features
ECC validation, software RAID and supported Infinity Guard capabilities require a properly configured system.

Frequently Asked Questions
Is this the boxed version?
No. AMD identifies 100-000001764 as the tray part; the boxed part has a different product code.
Will it work in any AM5 motherboard?
Do not assume so. The board vendor must explicitly list EPYC 4545P support and the correct BIOS.
Is 5.4GHz the base frequency?
No. The base clock is 3.0GHz; 5.4GHz is the stated maximum boost.
Does it include a cooler?
This is a tray/OEM listing; provide suitable compatible cooling separately.
Does the CPU provide 44 PCIe lanes on its own?
AMD lists 28 lanes from the CPU and up to 44 with the chipset. The motherboard determines usable connectivity.
Singular Expert Insight
Treat the CPU as one part of a validated server design. Its sixteen cores and 65W default TDP are useful planning points, but motherboard firmware, ECC memory support, cooling and software compatibility determine whether the finished system meets your needs.
Buyer’s Guide
✓ Buy it if You have a validated EPYC 4005 platform and need a 16-core single-socket server processor.
✕ Skip it if You need guaranteed consumer-board compatibility, a dual-socket CPU or an included retail cooling package.
→ Also consider Motherboard support list, BIOS, approved memory configuration, cooling clearance and software licensing.
