  • Six-channel DDR4-2933 support up to 768 GB memory capacity
  • 140 W TDP balances performance with server power budgets

Server-grade 18-core Xeon processor

The Intel Xeon Gold 6140 SR3AX delivers 18 cores at a base frequency of 2.3 GHz with a maximum turbo of 3.7 GHz. It fits the LGA 3647 socket and supports six-channel DDR4 memory up to 768 GiB. The 24.75 MB smart cache and 48 lanes of PCIe 3.0 suit multi-threaded server workloads.

140 W thermal envelope without included cooler

This processor carries a 140 W TDP and ships without a cooling device, so system integrators must supply a compatible LGA 3647 heatsink or liquid block. Under typical multi-core load the chip will draw up to its rated power, requiring adequate case airflow. Acoustic output depends entirely on the chosen cooling solution and fan curves configured in the platform firmware.

Boxed processor only — no accessories or software

The BX806736140 package contains the CPU alone; no thermal paste, mounting hardware or software licence is bundled. Buyers who need a pre-applied thermal interface or a validated cooling kit must source those separately. The lack of included accessories keeps the SKU focused on bulk deployment where custom cooling stacks are standard.

Questions sur cet article

How is the LGA 3647 processor installed and what step is often missed?

Align the gold triangle on the Intel Xeon Gold 6140 with the socket marker, lower the carrier frame, and secure the load plate. The step often missed is applying thermal paste before mounting the separate cooling solution, which is not included.

What maintenance or replacement will the Xeon SR3AX need later?

The processor itself requires no scheduled replacement. Maintenance consists of periodically cleaning the heatsink fins and replacing the thermal interface material every few years to maintain the 140W thermal design power dissipation.

What limit appears first under sustained load on this 18-core CPU?

The 140W TDP limit is reached first during sustained all-core workloads. The 2.3 GHz base frequency is guaranteed within this power envelope, while the 3.7 GHz turbo is opportunistic and duration depends on the cooler's capacity.
