I want to add 4gb ram to my laptop but confused which one should I buy as I can't figure out my ram type.
sudo dmidecode --type memory | less is giving this output
Handle 0x0025, DMI type 16, 23 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 16 GB Error Information Handle: No Error Number Of Devices: 2 Memory Device Array Handle: 0x0025 Error Information Handle: No Error Total Width: 64 bits Data Width: 64 bits Size: 4096 MB Form Factor: SODIMM Set: None Locator: Bottom - Slot 2 (right) Bank Locator: BANK 2 Type: DDR3 Type Detail: Synchronous Speed: 1600 MT/s Manufacturer: Kingston Serial Number: 43522522 Asset Tag: 9876543210 Part Number: HP687515-H66-MCN Rank: 1 Configured Memory Speed: 1600 MT/s Minimum Voltage: 1.35 V Maximum Voltage: 1.5 V Configured Voltage: 1.35 V
Can I add 4 GB ram? Which one should I buy one with 1.5V or 1.35V? In speed, it is showing 1600 MT/s. Should I go with 800 MHz or 1600 MHz because in some article it is mentioned that 1600 MT/s effective speed is 800 MHz.
Thanks in advance
