What the Xeon E7-4820 v3 is
The Xeon E7-4820 v3 is a 10 core fixed clock Haswell-EX part on LGA 2011-1 for 4S databases. Intel set 10 cores and 20 threads at 1.9 GHz with no turbo. Twenty five megabytes of last level cache cover workers. Power is 115 W on 22 nm from the second quarter of 2015.
Fixed clocks suit large 4S systems where predictability beats bursts. Three QPI links at 6.4 GT/s connect four sockets. Ten cores balance threads and per core memory bandwidth. No turbo means capacity math stays simple.
DDR4 and DDR3 with ECC over four channels to 1.5 TB per socket feed big guests. Buyers pick the 4820 v3 where 10 fixed cores per socket scale across 4S without turbo variance.
Socket and motherboard compatibility
The 4820 v3 fits LGA 2011-1 on Brickland 4S boards. E7-4800 validates to four sockets. Firmware must list the fixed clock SKU. LGA 2011-v3 Grantley boards never accept E7 EX parts.
Memory is DDR3 or DDR4 ECC, never mixed per board. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor docs decide RAS maps.
Memory, PCIe and cooling
DDR4-1333 to 1866 or DDR3 ECC over four channels to 1.5 TB per socket suits 4S databases. Mirroring options protect critical ranges. Even populations across sockets preserve NUMA balance.
PCIe 3.0 with 32 lanes per socket serves storage and networking. Mission critical fabrics matter more than accelerators. QPI links carry socket to socket traffic.
Cooling uses 4S heatsinks for 115 W continuous. Fixed clocks ease hot aisle planning. No retail cooler exists.
Upgrade paths
On the same socket the Intel Xeon E7-4809 v3 at 8 fixed cores below saves threads, while the Intel Xeon E7-4830 v3 at 12 cores with turbo adds bursts. All share LGA 2011-1 where listed.
A v4 refresh needs new firmware. The 4820 v3 holds fixed 10 core 4S where steadiness matters.
