Dears,
I try to upgrade a Gericom NB as described in the subject line. The original SO-DIMMS 2x64MB consist of fore 8Bit Mem-Chips, two on each side.
My replacement 2x256MB SO-DIMMS consist of 8x 4Bit Mem-Chips, fore on each side, and as result the NB recognizes only 256MB RAM.
For better understanding I would like to now if a Bios upgrade could help to get the full mem capacity or if this problem occurs due to hw layout of the mb or Sis630 chip.
Many thanks in advance.
Markus

FWIW, this is the datasheet for the SiS630 chip:
Integrated DRAM Controller 3-DIMM/6-Bank of 3.3V SDRAM Supports NEC Virtual Channel Memory (VC-SDRAM) Technology Supports Memory Bus up to 133 MHZ System Memory Size up to 1.5 GB Up to 512MB per Row Supports 16Mb, 64Mb, 128Mb, 256Mb, 512Mb SDRAM Technology
