I have an old Dell 640m which I desperately want to upgrade the RAM of. It currently contains these memory modules (a total of 1GB running at 533MHz). I have found the User Manual which (on page 158) states the following:
Memory module connector: two SODIMM connectors Memory module capacities: 256 MB, 512 MB, 1 GB, and 2GB Memory type: 1.8-V SODIMM DDR-2 Minimum memory: 256 MB Maximum memory: 2 GB
but how can I determine the maximum RAM speed that it can support?
Although I have searched online for this, I have found conflicting information, some even stating its maximum ram capacity is 4GB
I just ran $ dmidecode -t 16
# dmidecode 2.9 SMBIOS 2.4 present. Handle 0x1000, DMI type 16, 15 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 4 GB Error Information Handle: Not Provided Number Of Devices: 2
so would that be more trustworthy than the manual, or is that a fallback value?
