What the Xeon E3-1285 v6 is
The Xeon E3-1285 v6 is a four core, eight thread workstation processor from Kaby Lake-DT. It launched in August 2017 with a 4.1 GHz base and up to 4.5 GHz Turbo at 79 W. Four cores with Hyper-Threading at very high clocks cover entry workstations where single thread pace decides interaction.
Eight megabytes of Smart Cache feed CAD with background tools. The 4.1 GHz base was among the highest workstation bases of its year, while 4.5 GHz burst leads peaks. Seventy nine watts suit single socket towers.
HD Graphics P630 with 24 execution units from 350 MHz to 1150 MHz drives workstation displays with 4K output. P630 adds workstation driver paths over HD 630. Three displays run through eDP, DisplayPort and HDMI.
On 14 nm the 1285 v6 tops E3 v6 parts on clocks and graphics. Small offices pick it for CAD without dual socket cost. ECC memory with C236 boards suits reliability.
Socket and motherboard compatibility
The 1285 v6 fits LGA 1151 revision 1 on C236 workstation boards, not consumer 100 and 200 series boards for ECC use. C236 enables ECC memory and workstation management. Check the board CPU list for v6 stepping.
Boards wire two DDR4 channels with ECC for workstation loads. Professional GPUs take PCIe lanes for 3D. The Socket vs chipset: what decides whether a CPU works guide explains C236 against consumer chipsets.
The Core i7-7700K on the same socket is the consumer alternative without ECC. The Xeon E3-1275 v6 trims clocks where cost matters.
Memory, PCIe and cooling
DDR4-2400 or DDR3L-1866 in two channels up to 64 GB with ECC is the support. Matched pairs hold dual channel bandwidth for P630 output. ECC corrects errors in long CAD sessions.
Sixteen PCIe 3.0 lanes feed a workstation GPU plus NVMe storage. Single socket towers balance graphics and scratch SSDs. Board manuals detail slot sharing.
Seventy nine watts cool with tower air on the 75 mm pattern shared with LGA 1155, 1150 and LGA 1200. Sustained high clocks need steady airflow.
Upgrade paths
On LGA 1151 revision 1 there is no higher E3 v6 above the 1285 v6 on clocks, so growth means more memory or a discrete GPU. Past revision 1 a new workstation platform is required.
Most owners add SSDs and memory before new CPUs. The P630 covers office 3D without a discrete card.
