      RPL
      3100-RL+

Currently, we are shipping with AVX disabled by default, and we always recommend customers reach out to us about any AVX workloads they want to run, as this is a much more complex instruction set and requires more fine tuning on a per customer basis. It generates more heat and consumes more power, which can introduce instability.

You can enable AVX and test your workload to see how this performs. You will need to monitor the following items and report back to us your findings to ensure the system is operating within acceptable ranges.

Package power draw (can be measured via 'turbostat')
PSU power draw (can be measured per module in the 'sensor' tab of IPMI)
CPU package/core temps
If possible, can you let us know a before-and-after for these stats also

You can enable AVX in the BIOS:

Enter BIOS by pressing "F2" or "Del" during boot
Navigate to "AI Tweaker -> AVX Related Controls"
Enable "AVX2"
Ensure User Specify is set (This could be set to auto)
Set "AVX2 Ratio Offset" to 0
Set "AVX Voltage Scale" to 0
