Ampere Altra Max M112-30 socket: LGA 4926

What the Altra Max M112-30 is

The Ampere Altra Max M112-30 is a 112-core server processor with a 3.0 GHz sustained frequency. It runs 112 single-thread Arm v8.2+ cores with no turbo, so 112 cores give 112 threads. Cache is 1 MB of L2 per core plus a 16 MB shared system cache on a 7 nm process. Power is rated at 240 W max with about 158 W usage power in a 4926-pin FCLGA package with order part number AC-211224002.

Full 3.0 GHz clocks with 112 cores split the gap between 96 and 128-core parts, which is why the M112-30 suits buyers who want top frequency with near-flagship density. Ampere sold the M112-30 in the Max lineup. The chip supports enterprise RAS.

High clocks with near-flagship density suit performance cloud servers with DDR4 memory. That is why the M112-30 shipped in frequency-sensitive dense hosts.

Socket and motherboard compatibility

The M112-30 fits LGA 4926 performance dense servers with Altra Max support. It needs a 4926-land board with Ampere firmware and a BIOS that lists the M112-30. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Performance dense servers are the natural match. Boards listing the M112-30 accept the chip with a 240 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 240 W.

Upgrade paths

On the same socket, a move to an Altra Max M128-30 such as Ampere Altra Max M128-30 adds 16 cores at 250 W when density matters. An Altra Max M96-30 such as Ampere Altra Max M96-30 trims 16 cores at 220 W.

Newer AmpereOne needs a new platform. The LGA 4926 page lists the range.
