AMD ROCm 6.4.3 Released With A Few Fixes

Written by Michael Larabel in AMD on 8 August 2025 at 10:25 AM EDT. 3 Comments
While we eagerly await the release of ROCm 7.0, ROCm 6.4.3 is out today as the newest point release to the ROCm 6.4 open-source GPU compute stack.

ROCm 6.4.3 open-source Git tags started appearing on Thursday and this morning the ROCM documentation was updated to outline the ROCm 6.4.3 changes. It mostly comes down to a few fixes and with that it's for those using the DKMS packaged AMDGPU kernel graphics driver if you aren't relying on the upstream Linux kernel AMDGPU/AMDKFD code.

The noted ROCm 6.4.3 changes are:
AMDGPU driver updates

- Resolved an issue causing performance degradation in communication operations, caused by increased latency in certain RCCL applications. The fix prevents unnecessary queue eviction during the fork process.

- Fixed an issue in the AMDGPU driver’s scheduler constraints that could cause queue preemption to fail during workload execution.

ROCm SMI update

- Fixed the failure to load GPU data like System Clock (SCLK) by adjusting the logic for retrieving GPU board voltage.

That's it for the noted ROCm 6.4.3 changes. There isn't any listed changes with ROCm 6.4.3 as it pertains to the GPU hardware support, operating system support, or the other software component versions as part of the ROCm ecosystem.
