Had the SDRAM 2 delivered return x 512 MB, as they are for the older PC Fujitsu Siemens SCENIC T i810, mainboard D1170, incompatible. The design of techn. Computer Handbook - 2 DIMM slots for 16 to 512 Mbyte main memory (SDRAM memory modules for PC100 specification) without ECC was interpreted by me so that 2 pieces à SDRAM 512MB would fit.
Unfortunately is not the case, so that the manual says should be meant, it can be plugged into the 2 DIMM slots total of only 16 to more than 512 MB.
