[Info-vax] Alpha Personal Workstation question

[Mazzini Alessandro]

Again, thanks for the trouble of checking.

According to a person I was discussing this with, he said that there were a 
bit of cases he experienced ( read a lot ) where putting 1.5gb and 1.25gb 
caused issues (crashes etc) when under heavy load ( so addressing all the 
memory ). Lowering to 1gb apparently resolved the issue.
