Silver rectangular processor with gold contact pads and green substrate, Intel Xeon Gold 6128 label visible

Intel

Intel Xeon Gold 6128 SR3J4 6 Core 3.40GHz 19.25MB 115W FCLGA3647 cpu accessory

SKU CH-4TXY-EX4W8

Six-core Xeon processor running at 3.40 GHz with 19.25 MB cache and 115 W TDP for Socket 3647 platforms

  • 6-core design handles parallel workloads efficiently
  • 40 GHz base clock delivers consistent processing speed
  • Turbo up to 3.70 GHz accelerates demanding tasks
  • 25 MB L3 cache reduces data latency
  • 115 W TDP balances performance with thermal limits

Server-grade processor

The Intel Xeon Gold 6128 is a 6-core server processor built on the SkyLake architecture. It operates at a base frequency of 3.40GHz and can boost up to 3.70GHz depending on workload demands. The part carries the SR3J4 designation and fits the FCLGA3647 socket platform.

Thermal design and socket fit

With a thermal design power of 115W, this CPU requires cooling solutions rated for that envelope in a server chassis. The FCLGA3647 land-grid array socket uses a carrier and retention mechanism designed for rack-mount density and long-term contact reliability under sustained loads.

Upgrade path for six-core deployments

This unit replaces an existing six-core Xeon in a compatible dual-socket board when higher base clocks or the larger 19.25MB L3 cache are needed. The jump is worth it for workloads that scale with per-core frequency rather than core count alone. Buyers needing more than six cores per socket should look elsewhere.

Questions about this item

What does the FCLGA3647 socket standard mean for cooler compatibility?

The processor uses the FCLGA3647 socket, so any cooler must be rated for that specific socket type to ensure proper mounting and thermal contact.

What physical clearance does the 115 W TDP require for a heatsink?

A 115 W thermal design power demands a server-grade heatsink rated for at least that wattage with adequate airflow across the fin stack.

How is the processor seated in the FCLGA3647 socket, and what step is often missed?

Align the gold triangle on the processor with the socket triangle, lower it vertically without force, then close the load plate and torque the captive screws in a diagonal sequence.
