Bounce a temporary mix of your already recorded tracks and temporarily
inactivate those tracks (Track menu or right-click menu on the strip) to
make room for the new ones. Use the bounce as the only track playing and
active while you record the rest. Maybe this will save enough
horsepower so that your system deals with the load. At mix time, relax
the latency constraint and reactivate all the tracks.

HTH, have fun.
