What the Xeon E5-2698A v3 is
The Xeon E5-2698A v3 is an OEM Haswell-EP sixteen core with high base clocks for vendor systems on LGA 2011-v3. Intel set sixteen cores and 32 threads at 2.8 GHz base with turbo to 3.2 GHz. Forty megabytes of Smart Cache serve dense tenants. Power is 165 W on 22 nm from November 2014. High sustained clocks suit vendor clouds that pay for speed per core at scale.
A 2.8 GHz base is high for sixteen cores and keeps all core work direct. Narrow turbo range reflects sustained thermal planning at 165 W. Thirty two threads consolidate guests with ECC protection. No integrated graphics exist. Vendor validation gates this OEM stepping to specific systems. Used buyers meet it in system pulls where generic support varies.
DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for vendor deployments where fast sixteen cores at 165 W are the density choice.
Socket and motherboard compatibility
The E5-2698A v3 fits LGA 2011-v3 on vendor C612 Grantley platforms. OEM firmware matrices decide support, so generic boards may reject the stepping. Verify the exact system before sourcing used parts. Desktop X99 never accepts this server OEM chip.
Memory is ECC RDIMMs over four channels. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so follow vendor population rules. Cooling uses vendor 165 W heatsinks with strong rack airflow.
Retail sixteen core E5 v3 offer wider board support where OEM locks bind. Check microcode before any cross vendor plan.
Memory, PCIe and cooling
DDR4 ECC quad channel per socket suits large tenants. Even DIMM maps protect NUMA balance. Large RDIMMs reach high counts. Speed steps with population per manual.
Forty PCIe 3.0 lanes per socket feed fabric and NVMe for cloud storage. NUMA placement across QPI links matters at sixteen cores. Vendor manuals detail slot maps.
Vendor 165 W cooling sustains high base clocks with cool inlets. No retail cooler exists. Power delivery and inlet air decide all core residency.
Upgrade paths
On the same socket the Intel Xeon E5-2698 v3 at 2.3 GHz to 3.6 GHz offers retail availability with wider turbo on similar boards. The Intel Xeon E5-2680 v3 with twelve cores is a lower density retail step. Both need platform checks.
Newer sockets replace Grantley. The E5-2698A v3 covers OEM clouds where fast sixteen cores at 165 W are specified.
