I think Nick is right, and in fact the stata web page says:

"Stata/SE also allows matrices up to 11,000 x 11,000 on computers with
sufficient memory. An implication of this is that Stata/SE can estimate
models with more independent variables (up to 10,998) and estimate
certain panel-data models with larger time-series within panel. "

And

"In addition, Intercooled Stata can have at most 798 right-hand-side
variables in a model."

(== matrices of 800 x 800 is the maximum)
