Apple generally does not sell a product four to five months before its delivery. However, the global memory shortage shows that this is not ordinary. AI servers require a lot of RAM, and this situation is seriously affecting Apple's top Mac RAM inventory.

M3 Ultra Mac Studio will ship in August or September with 256GB RAM

If you order an M3 Ultra Mac Studio today with the remaining RAM upgrade, Apple says it will arrive in four to five months.

This means that the 256GB RAM option ordered in April will arrive in August or September if the shipping estimate is accurate.

Upgrading from 96GB to 512GB of memory means a $2000 upgrade for a $4000 Mac.

However, for a $6000 high-quality Mac, it's not as simple as just playing with the configurator to find the most expensive option.

Apple had already removed the highest configuration when it stopped selling the 512GB RAM version last month.

The standard M3 Ultra Mac Studio that comes with 96GB RAM is also not quite ready.

Apple is giving delivery estimates between April 20 and April 27. This is the same as the currently high-demand affordable MacBook Neo.

Still, with four to five months of shipping delays, it’s not surprising that Apple had to remove its 512GB RAM option — even if customers are willing to pay.

If the situation does not change, this certainly creates challenges for future Ultra chips that will be introduced. 512GB memory was a new peak for the M3 Ultra.

In the meantime, Apple has never produced an M4 Ultra, and the M4 Max was replaced with the M5 Max. The Mac Studio currently comes with M4 Max or M3 Ultra chips.
