If there was more RAM, the code exhibiting the problem could have been loaded into the additional RAM instead of the flakey RAM. This would depend highly on the exact usage patter by processes invoked during install, including, but not limited to, their invocation order, etc.. There is no evidence, short of a shuffle, that will guarantee you that the problem is resolved, not masked by the additional RAM. You will need to do a full shuffle so that an 8M situation without the possibly flakey RAM is also tested (and verified to fail).
