you could wrap the name by an \url{} macro like:

\documentclass{article}
\usepackage{url}
\begin{document}

a aaaa aaaaaa aaaaaaaaa aaaaaaaaaaaa
\url{SECONDARY_EXTSRAM_LARGEPOOL_NORMAL}
\end{document}

This happens to allow hyphenations also after underscores. And checking
url.sty shows you which other characters also allow this.
