Are 256Mbit SDRAMs supported?
The 82443BX does not support 256Mbit technology SDRAM. 128Mbit technology SDRAM using 16MX8 devices has been tested in the Intel® 82440BX System Validation (SV) platform using the 82443BX C-1 stepping. This SDRAM memory configuration was double-sided. Each SDRAM DIMM module therefore contained a total of 256MB of memory. A total of four DIMM modules were available for testing. For further information please see page 25 of the specification update. There were no detection or sizing problems with this SDRAM memory array using the 82440BX SV board and 82440BX SV BIOS. The 82440BX AGPset supports the use of 128Mbit technology SDRAM memory using the 82443BX C-1 stepping as described in this paragraph.
