AMD EPYC 7301 socket: SP3
The AMD EPYC 7301 uses the SP3 socket on server boards. It is a 16 core Naples chip with full L3 cache for balanced virtualization racks.

Motherboard compatibility
AMD EPYC 7301 needs a motherboard with a SP3 socket. Chipset by chipset data for this codename is not recorded yet. See the SP3 chipset list and the board maker's CPU support list.

What the EPYC 7301 is
The EPYC 7301 is a sixteen core, thirty two thread server processor with a 2.2 GHz base and up to 2.7 GHz boost. It carries 8 MB of L2 with 64 MB of shared L3 and a 170 W TDP on the 14 nm process. AMD launched it on June 20, 2017; database entries claiming 3.0 GHz boost conflict with published specs and are not used here.
Full 64 MB L3 doubles the 7281 for cache sensitive databases that fit working sets on die. The multiplier is locked.
There is no integrated graphics. ECC memory with RDIMM and LRDIMM support is standard. Launch lists agree near $825. The 170 W rating pairs with DDR4-2666, dropping to 155 W with DDR4-2400.
Socket and motherboard compatibility
The 7301 fits SP3 on server boards with eight channel DDR4. Boards need a BIOS with Naples support and the exact SKU on the vendor list. It runs in one or two socket designs.
Server boards carry 128 PCIe 3.0 lanes per CPU for NICs, NVMe and accelerators. Rack chassis need front to back airflow with vendor qualified heatsinks.
The chip ships tray only with no cooler. The EPYC 7281 is the cost optimized sibling on the same boards with half the L3.
Memory, PCIe and cooling
Memory support is DDR4-2666 in eight channels up to 2 TB, with ECC and RDIMM or LRDIMM modules. DDR4-2400 drops the TDP to 155 W with some bandwidth. Sixteen DIMMs per socket hold rated speed most easily.
PCI Express arrives as version 3.0 with 128 lanes from the CPU. Cooling uses vendor 170 W server heatsinks with directed chassis airflow.
Upgrade paths
On the same socket the step up is the EPYC 7351 with higher clocks on the same cache, keeping board and DDR4. The 7301 keeps its place where full cache covers databases at lower clocks.
Moving past SP3 means a new board on a current server platform. Rack owners usually add memory or network cards before replacing processors.
Frequently asked questions
What socket does the EPYC 7301 use?
It uses SP3 on server boards with a BIOS that lists Naples parts. It runs in one or two socket designs.
How many cores does the 7301 have?
Sixteen cores with multithreading give thirty two threads at 2.2 GHz base with up to 2.7 GHz boost, at 170 W.
What is the boost clock of the 7301?
2.7 GHz per published specs. Database 3.0 GHz claims conflict and are not used here.
How much L3 does the 7301 have?
64 MB against 32 MB on the 7281. Full cache suits cache sensitive databases.
What memory does the 7301 support?
DDR4-2666 in eight channels up to 2 TB, with ECC modules.
