Wetin you need know

AMD Instinct MI355X na CDNA 4 datacenter compute accelerator with 288 GB of HBM3E memory, 256 compute units and OAM module form factor.

Reference specifications wey dem record no be tested performance or operating-system compatibility verdict. Verify di exact model and platform wit di manufacturer.

Model identity and limitations

AMD Instinct MI355X target GPU compute inside supported datacenter systems. AMD list di MI355X as OAM module for servers. Use di exact server configuration to establish cooling, power provisioning, supported host software and available accelerator partitions. Peak bandwidth and board-power specifications no dey measure complete application or server.

Check di complete server platform

Confirm di server model, module identity, firmware and cooling configuration with di system vendor before you buy parts or change software. OAM module need compatible accelerator baseboard and server integration; host-interface specification alone no dey establish physical compatibility.

Troubleshoot with di supported software stack

Record di server firmware, operating system, ROCm version, reported device identities and exact error before you make changes. Compare dat combination with AMD and di server vendor support documentation. Separate reported partitions or compute dies from physical accelerator modules.

Run di vendor documented acceptance checks inside maintenance window. Save di previous supported driver/runtime configuration and recovery procedure before you upgrade. If new runtime cause regression, restore di previously supported stack using di system vendor documented method; avoid to delete kernel or driver files by hand.
