What the Xeon E7-4850 v3 is
The Xeon E7-4850 v3 tops E7-4800 4S parts on LGA 2011-1 for ERP systems. Intel set 14 cores and 28 threads at 2.2 GHz base with turbo to 2.8 GHz. Thirty five megabytes of last level cache cover large tenants. Power is 115 W on 22 nm from the second quarter of 2015.
Fourteen cores maximize threads in 4S without moving to 8S E7-8800 pricing. Three QPI links at 8 GT/s connect four sockets. Turbo helps dialog steps while batch work uses all cores. The 115 W rating keeps 4S racks efficient.
DDR4 and DDR3 ECC over four channels to 1.5 TB per socket feed ERP guests. Buyers pick the 4850 v3 where 4S scale with 14 cores per socket hosts the most tenants per node.
Socket and motherboard compatibility
The 4850 v3 fits LGA 2011-1 on Brickland 4S boards. E7-4800 validates to four sockets. Firmware must list the 14 core stepping. Grantley LGA 2011-v3 never accepts EX parts.
Memory is DDR3 or DDR4 ECC per board, never mixed. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor docs decide RAS options.
Memory, PCIe and cooling
Memory to 1.5 TB per socket with ECC suits ERP databases. DDR4 at 1866 preferred. Mirroring protects critical tenants with capacity cost.
PCIe 3.0 with 32 lanes per socket serves networking and storage. ERP landscapes need reliable fabrics. QPI carries cross socket dialog traffic.
Cooling uses 4S heatsinks for 115 W continuous. No retail cooler exists. Even inlet temperatures protect turbo.
Upgrade paths
On the same socket the Intel Xeon E7-4830 v3 at 12 cores below saves cost, while the Intel Xeon E7-8860 v3 moves to 16 cores in 8S class above. All share LGA 2011-1 where vendor firmware lists them.
A v4 refresh needs new microcode. The 4850 v3 leads 4S 14 core Haswell-EX.
