24-core EPYC 7443P server processor

The AMD EPYC 7443P is a 24-core, 48-thread server CPU built on the Milan architecture using 7 nm process technology. It operates at a base frequency of 2.85 GHz with a maximum turbo frequency of 4.0 GHz and features 128 MB of L3 cache. The processor fits the Socket SP3 platform and has a thermal design power of 200 W.

Suited for dense DDR4 platforms.

This processor suits data centre deployments that require 24 cores and eight-channel DDR4 3200 memory support with up to 128 PCIe 4.0 lanes. Buyers needing a lower core count or a reduced thermal envelope for smaller chassis should evaluate alternative SKUs. The part is sold without a cooling device, so integrators must provide a compatible SP3 cooler.

128 MB L3 cache and eight-channel DDR4 3200

The 128 MB L3 cache feeds 24 cores to reduce latency on complex, multi-threaded workloads. Eight memory channels running at DDR4 3200 deliver high aggregate bandwidth for memory-bound applications. Verify that your motherboard supports the SP3 socket and 200 W TDP before purchase.

Questions about this item

Will the EPYC 7443P run in my existing SP3 motherboard alongside older EPYC processors?

The 7443P fits Socket SP3 and supports DDR4 3200 across eight channels, so it works in SP3 platforms qualified for Milan; mixed CPU generations in one system are not supported.

How can I confirm the 24-core 2.85 GHz processor is hitting its 4.0 GHz max turbo after installation?

Check BIOS for correct Milan microcode, then monitor all 48 threads under load — sustained clocks near 4.0 GHz with 128 MB L3 active indicate proper operation.

What ships with the 100-000000342 tray and what must I source separately?

The tray contains the processor only; a compatible SP3 cooler rated for 200 W TDP and DDR4 3200 memory modules are required separately.
