AMD EPYC 4245P 6-Core 3.9 GHz 65W Server Processor 100-100001555WOF

SKU CH-JS1A-T3BJ0 MPN 100-100001555WOF

Six-core server processor with 12 threads, 32 MB L3 cache, 3.9 GHz base clock and 65 W TDP for Socket AM5 DDR5 platforms

  • NameEPYC 4245P
  • CPU Socket TypeSocket AM5
  • # of CoresSix-Core
  • L3 Cache32MB
  • 64-Bit SupportYes
  • Integrated Memory Controller SpeedDDR5 5600

Option EPYC 4245P

Struck-through versions exist but are not stocked here.

  • Six cores and twelve threads handle parallel workloads efficiently
  • Base clock 3.9 GHz with boost up to 5.4 GHz delivers responsive performance
  • 32 MB L3 cache reduces latency for frequent data access
  • DDR5 5600 memory controller enables high-speed system memory
  • 65 W TDP keeps power draw low for entry-level servers

Entry-level server processor for small business

The AMD EPYC 4245P is a six-core, twelve-thread CPU built on the EPYC 4005 series architecture for entry-level server deployments. It targets small businesses and hosted service providers that need dependable performance for everyday workloads. The processor fits Socket AM5 platforms and operates within a 65 W thermal envelope.

DDR5 5600 memory controller and Zen5 core design

The integrated memory controller supports DDR5 at 5600 MT/s, providing the bandwidth needed for responsive all-day processing. Twelve threads across six Zen5 cores handle multi-threaded tasks such as virtualisation, web hosting and database queries. Built-in security features help protect data without requiring additional hardware.

32 MB L3 cache and 5.4 GHz boost headroom

A 32 MB L3 cache reduces latency for frequently accessed data, while the 5.4 GHz maximum boost clock delivers extra speed for bursty workloads. The 65 W base power keeps cooling requirements modest for dense or quiet chassis. Buyers needing more than sixteen cores or higher sustained throughput should consider processors from the 7000, 8000 or 9000 series.

Questions about this item

Will the integrated DDR5 5600 memory controller require any firmware updates to maintain compatibility with future DDR5 modules?

The processor includes an integrated DDR5 5600 memory controller; motherboard BIOS updates handle future module compatibility, not the CPU itself.

What thermal limit is reached first when all six cores sustain the 5.4 GHz boost clock under continuous load?

The 65 W TDP is the primary limit; sustained all-core boost clocks are constrained by this power envelope and the cooler's capacity.

How much heat does the 65 W TDP produce when the chip runs all day at the 3.9 GHz base clock?

At base frequency the processor dissipates up to 65 W of heat, requiring a server cooler rated for at least that thermal design power.
