AMD EPYC 7371 socket: SP3
The AMD EPYC 7371 uses the SP3 socket on server boards. It is a 16 core Naples server chip for high clock single socket hosts.

What the EPYC 7371 is
The EPYC 7371 pushes Naples clocks with sixteen cores and multithreading. It launched in November 2018 with a 3.1 GHz base and up to 3.8 GHz boost at 200 W. AMD targets high frequency servers that need per core speed with server I/O.
Sixty four megabytes of L3 with 8 MB of L2 feed databases across 32 threads. The high base for a 16 core Naples part sustains transactions. Boost reaches 3.8 GHz for single thread peaks. Note that Technical City lists 170 W and TR4 socket for this SKU, while AMD specifications list 200 W and SP3, and this page uses the manufacturer values.
No integrated graphics is included. The process is 14 nm. DDR4 ECC in eight channels up to 2 TB suits large memories.
Socket and motherboard compatibility
The 7371 fits SP3 on server boards, not TR4 despite some list errors. Vendors wire 1P and 2P boards for Naples with 200 W power stages. Late 2018 BIOS builds carry 7371 IDs.
Eight channel DDR4 ECC RDIMMs up to 2666 MT per s carry large datasets. Balanced population sustains bandwidth near 170.6 GB per sec. The Socket vs chipset: what decides whether a CPU works guide covers server board lists.
Single socket use extracts the high clocks without inter socket latency. Dual socket operation remains supported where boards allow.
Memory, PCIe and cooling
DDR4 ECC in eight channels up to 2 TB covers high frequency databases. Matched DIMMs across channels feed 32 threads. Start with 256 GB for in memory work.
One hundred twenty eight Gen3 lanes from the CPU connect NVMe and 25 GbE at server rates. High clock hosts benefit most from low latency storage. Board splits follow vendor designs.
Two hundred watt server heatsinks with strong airflow are required. No retail cooler applies. Follow vendor torque and thermal interface guidance.
Upgrade paths
On the same socket, the AMD EPYC 7261 trims to eight cores at 170 W for efficient hosts. Larger 24 and 32 core Naples parts add threads where listed. Both share SP3 after a BIOS check.
Single socket Ryzen lacks the lanes and channels for such hosts. It suits labs rather than production.
Past SP3 Rome and Milan bring more cores per socket on many boards after updates. The 7371 covers high clock sixteen core servers where frequency matters.
Frequently asked questions
What socket does the EPYC 7371 use?
It uses SP3 on server boards, not TR4 as some lists show.
