Normally during boot a basic test is run, but if you Stop-A into the PROM itself you can manually run a more thorough memory test, although I forget how (probably 'test memory' or similar depending on PROM version). Although only the larger servers have a keyswitch, all systems (AFAIK) have a 'diag-switch?' PROM variable which you can set to true to make the system run more advanced tests automatically when booting.
