A100 SXM4 TGP limitCurrent

Virtual GPU Forums General Discussion

Hello,

We have been debugging a system with odd power limits on an A100 system and finally found the limits within the SXM4 module itself.

What commands must be run in nvflash to reset the limits to 400000mW? Any attempted command returns “Failed to update InfoROM PPO data”.
