Important

Action required: Upgrade for NVLink Recovery

In release 1.0.6 NVLink Recovery remains enabled by default. To ensure proper functionality and system stability, you must upgrade all components in the rack to release 1.0.6 or later, including compute nodes and NVSwitch.

Failure to upgrade the entire rack may lead to incompatibility issues and unexpected behavior during NVLink Recovery operations.

Important

Action required: SBIOS patch for Hynix and Micron memory support

In release 1.0.6, the SBIOS version is rolled back to 02.05.05. This version does not natively support Micron and Hynix memory modules. To ensure proper support for HPMs with these memory modules, apply the SBIOS patch (NVOnline 1151413 PG548 Memory Support SBIOS Patch for 02.05.05).

Without this patch, systems with Micron or Hynix memory modules fail to boot with SBIOS version 02.05.05.

Important

Action required: DOCA GPG-Key Update

In release 1.0.6, the DOCA version is updated to 3.2.1-044413 which requires a new GPG key. This key update is specific to this release until DGX OS 7.5.0 becomes public on 3/31/26. Please refer to the FW Update guide for the detailed install steps.

Without this patch, DOCA will not work.
