He said his "Memphis Supercluster" began operations at approximately 4:20 am and was a partnership between X and Nvidia. Coincidently, 4/20 was Adolf Hitler's birthday it was also codeword for marijuana and consumption cannabis-oriented celebrations on April 20. 

He claimed the supercomputer cluster featuring 100,000 liquid-cooled H100 GPUs on a single RDMA fabric. According to Musk, this setup gives xAI "a significant advantage in training the world's most powerful AI by every metric by December this year."

Given issues with xAI's Grok chatbot throughout the year, sceptics would be justified in questioning whether Musk is telling the truth or something he dreamed up in what his daughter Jenna called one of his “ketamine-fuelled hazes.”

According to a report by News Channel 3 WREG Memphis, the startup of the massive AI training facility raised questions among local residents and officials about its impact on the area's power grid and infrastructure.

WREG reports that Doug McGowen, president of Memphis Light, Gas and Water (MLGW), previously stated that xAI could consume up to 150 megawatts of power at peak times. This substantial power requirement has prompted discussions with the Tennessee Valley Authority (TVA) regarding the project's electricity demands and connection to the power system.

The TVA told the local news station, "TVA does not have a contract with xAI. We are working with xAI and our MLGW partners on the proposal's details and electricity demand needs."

The local news outlet confirms that MLGW has stated that xAI moved into an existing building with already existing utility services. Still, the full extent of the company's power usage and its potential effects on local utilities remain unclear. To address community concerns, WREG reports that MLGW plans to host public forums in the coming days to provide more information about the project and its implications for the city.

Musk is avoiding power issues by installing a fleet of 14 VoltaGrid natural gas generators that provide supplementary power to the Memphis computer cluster. At the same time, his company is negotiating an agreement with the local power utility.
