[dmidecode] dmidecode does not show DDR SDRAM size, speed..

[shen long]

I wonder if it can be solved, this is the mainboard:

Handle 0x0001, DMI type 1, 25 bytes
System Information
        Manufacturer: KOB
        Product Name: KOBP4M266A
        Version: 1.0
        Serial Number: 00000000
        UUID: Not Settable
        Wake-up Type: Modem Ring

This is the real info:
bank 1 DDR SDRAM 333 MHz (PC2700) 256 MB
bank 2 DDR SDRAM 333 MHz (PC2700) 256 MB

This is the output of dmidecode --type memory


# dmidecode 3.0
Scanning /dev/mem for entry point.
SMBIOS 2.3 present.
