10 col. RAM versus 11 col. RAM in US-IIi?

Anybody know how to tell whether the RAM in an UltraSPARC IIi-based
machine (U5/10, etc) is 10-column or 11-column, *without* powering the
machine down or going to OBP?

Here's all I know to get so far:

root@chip:~> memconf -v
memconf: V1.43 31-Oct-2001 http://www.4schmidts.com/unix.html
hostname: chip.mrbill.net

1 UltraSPARC-IIi cpu, cpu freq: 440MHz, system freq: 147MHz
