One comment on “Hacking around Fujitsu-Siemens RX300 S3 S4 S5 servers

  1. There is a method to force RX300 use non-OEM Fujitsu memory and do not display “Non Fujitsu Siemens Company Memory Modules detected – Warranty restricted!” The protection is inside FBDIMM EEPROM chip. Thus need utility like SPDTool to copy FSC Signature from original module to any other like Kingston, Hynix etc. I did this procedure and now it’s running maximum 24GB/slot configuration without any single problem.
