Apple Removes 512GB RAM Option from Mac Studio Amid Global DRAM Shortage
In a recent and unexpected move, Apple has discontinued the 512GB RAM upgrade for its Mac Studio, reducing the maximum available memory to 256GB. This change is likely a response to the ongoing global shortage of Dynamic Random-Access Memory (DRAM) chips, which has significantly impacted the tech industry.
Background on Mac Studio’s Memory Configurations
The Mac Studio, introduced as a high-performance desktop solution, initially offered a range of memory configurations to cater to various professional needs. The base model started with 36GB of unified memory, with upgrade options extending up to 512GB, particularly for configurations equipped with the M3 Ultra chip. This extensive memory capacity was especially appealing to professionals engaged in resource-intensive tasks such as video editing, 3D rendering, and running complex simulations.
Details of the Recent Change
As of March 5, 2026, Apple has quietly removed the 512GB RAM option from the Mac Studio’s configuration page. Consequently, the highest memory configuration now available is 256GB. In addition to this reduction, the cost to upgrade from 96GB to 256GB of RAM has increased from $1,600 to $2,000. Customers opting for the 256GB configuration are also facing extended shipping times, with estimates stretching into May.

Implications of the Global DRAM Shortage
The removal of the 512GB RAM option is likely a direct consequence of the global DRAM shortage. This shortage has led to increased prices and limited availability of memory components across the industry. The scarcity is attributed to several factors, including heightened demand for high-bandwidth memory (HBM) in artificial intelligence (AI) accelerators and disruptions in the supply chain. For instance, Qatar, a major helium supplier essential for semiconductor manufacturing, suspended shipments in early March, exacerbating the situation.

Impact on Professionals and AI Enthusiasts
The Mac Studio’s high memory configurations have been particularly attractive to professionals and AI enthusiasts who require substantial RAM to run large language models (LLMs) and other memory-intensive applications locally. The reduction in available memory options may prompt these users to seek alternative solutions or adjust their workflows to accommodate the new limitations.
Future Outlook
Apple is anticipated to release M5 Max and M5 Ultra versions of the Mac Studio later in 2026. However, it remains uncertain whether the 512GB RAM option will be reinstated with these updates. The availability of such high-density memory configurations will largely depend on improvements in the global DRAM supply chain.

Conclusion
Apple’s decision to remove the 512GB RAM option from the Mac Studio underscores the widespread impact of the global DRAM shortage on the technology sector. Professionals relying on high-memory configurations may need to explore alternative solutions or adjust their expectations until the supply chain stabilizes.
