64-core Arm server processor

The Ampere Altra Q64-30 is a 64-core server processor built on TSMC 7 nm FinFET technology. It runs at a consistent 3.0 GHz frequency across all single-threaded cores. The chip fits the LGA 4926 socket and targets scale-out cloud workloads, web serving and containerised applications that benefit from high core counts and deterministic performance.

Thermals noise and 124W power

Average CPU power is rated at 124W at the consistent 3.0 GHz operating frequency. The TSMC 7 nm process helps maintain this fixed frequency without turbo excursions that complicate thermal planning. Steady power draw simplifies cooling infrastructure design for dense rack deployments where predictable heat output matters more than peak bursts.

Upgrade path and multi-socket value

The processor supports up to 16 DDR4-3200 DIMMs across eight 72-bit channels with ECC for a maximum of 4 TB memory. It provides 128 lanes of PCIe 4.0 plus an optional 64-lane CCIX link for multi-socket configurations. Buyers who need more than 64 cores or larger shared-memory domains should evaluate dual-socket platforms; those whose workloads fit within a single socket gain simpler topology and lower licensing costs.

Questions sur cet article

How is the LGA 4926 processor seated, and what step is most often missed?

Align the notches on the Q64-30 with the socket keys, lower it straight down without tilting, then engage the retention lever fully; the step most often missed is verifying the lever clicks into its locked position before applying thermal paste.

What maintenance will the DDR4 3200 memory subsystem need over time?

The eight-channel controller supports up to 16 DDR4-3200 ECC DIMMs; plan to reseat modules and clear dust from slots during scheduled server maintenance, and replace any DIMM that logs correctable errors exceeding platform thresholds.

At what power level does the 64-core chip hit its thermal limit under sustained load?

The processor maintains a consistent 3.0 GHz frequency at its 124 W average power rating; sustained workloads that push package power above this level will trigger frequency throttling to stay within the thermal envelope.
