What the Xeon E7-4830 v3 is
The Xeon E7-4830 v3 is a 12 core turbo Haswell-EX part on LGA 2011-1 for 4S analytics. Intel set 12 cores and 24 threads at 2.1 GHz base with turbo to 2.7 GHz. Thirty megabytes of last level cache feed queries. Power is 115 W on 22 nm from the second quarter of 2015.
Turbo separates it from fixed E7-4800 parts in bursty analytics. Three QPI links at 8 GT/s tie four sockets. Twelve cores balance per socket licenses and threads. The 115 W envelope fits 4S racks without top bin heat.
DDR4-1333 to 1866 or DDR3 with ECC over four channels to 1.5 TB per socket feed big memory joins. Buyers pick the 4830 v3 where 12 turbo cores per socket accelerate 4S databases.
Socket and motherboard compatibility
The 4830 v3 fits LGA 2011-1 on Brickland 4S boards with E7 v3 firmware. E7-4800 validates to four sockets. LGA 2011-v3 boards never accept EX silicon despite shared counts.
DDR3 or DDR4 ECC populates four channels, never mixed. The Socket vs chipset: what decides whether a CPU works guide covers ideas, vendor RAS guides decide mirroring.
Memory, PCIe and cooling
Memory to 1.5 TB per socket with ECC and up to 85 GB/s suits analytics. DDR4 at 1866 is preferred where boards allow. Balanced populations protect join performance.
PCIe 3.0 with 32 lanes per socket serves HBAs and 10 GbE fabrics. Analytics nodes need I/O bandwidth for scans. QPI carries cross socket shuffles.
Cooling uses 4S heatsinks for 115 W with data center airflow. Turbo bursts need cool inlets. No boxed cooler ships.
Upgrade paths
On the same socket the Intel Xeon E7-4820 v3 at fixed 1.9 GHz below trades bursts for steadiness, while the Intel Xeon E7-4850 v3 at 14 cores adds threads above. All share LGA 2011-1 where listed.
A v4 move needs Broadwell-EX firmware. The 4830 v3 leads turbo 12 core 4S in Haswell-EX.
