Thanks Richard for your follow up. I will clean the dimm slot with
electronic 99% alcool because and will retest ram again.
Contact clean contain petrol solvent and it not the best for cleaning
mainboard sockets. It's more recommended for cleaning connectors.
Yesterday was a hot evening and this not helped me to diagnose my
SPARCstation. I'll do a follow up here after cleaning.
But my question about memory slot configuration with openboot remain
unanswered. It is possible to setup dimm 01to be the first simm to align
