Ampere Altra Q64-30 socket: LGA 4926

What the Altra Q64-30 is

The Ampere Altra Q64-30 is a 64-core server processor with a 3.0 GHz sustained frequency. It runs 64 single-thread Arm v8.2+ cores with no turbo, so 64 cores give 64 threads. Cache is 1 MB of L2 per core plus system cache on a 7 nm process. Power is rated at 180 W max with about 124 W usage power in a 4926-pin FCLGA package with order part number AC-106418002.

Full 3.0 GHz clocks with 16 fewer cores than the 80-core parts trims power while keeping frequency, which is why the Q64-30 suits balanced cloud nodes. Ampere sold the Q64-30 in the launch lineup. The chip supports enterprise RAS with ECC memory throughout.

Balanced clocks and core count suit mainstream cloud servers with DDR4 memory. That is why the Q64-30 shipped in balanced virtualization hosts.

Socket and motherboard compatibility

The Q64-30 fits LGA 4926 balanced cloud servers with Altra support. It needs a 4926-land board with Ampere firmware and a BIOS that lists the Q64-30. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Balanced virtualization hosts are the natural match. Boards listing the Q64-30 accept the chip with a 180 W heatsink.

Memory, PCIe and cooling

Memory is eight channels of DDR4-3200 ECC through the on-chip controllers, up to 4 TB per socket. PCIe Gen4 with 128 lanes per socket feeds storage and networking. Cooling uses server heatsinks rated for 180 W.

Upgrade paths

On the same socket, a move to an Altra Q80-30 such as Ampere Altra Q80-30 adds 16 cores at 210 W when density matters. An Altra Q64-22 such as Ampere Altra Q64-22 drops clocks to 2.2 GHz at 95 W for efficiency.

A move to Altra Max adds cores. The LGA 4926 page lists the range.
