Random Access Memory

Is a computer component to hold fast moving data

Characteristics

CAS Latency

• The lower, the better

Speeds

• 3200 MT/s = 3200 MHz =

DDR4

• 260 pins are for laptop = SODIMM
• 288 pins are for PC = DIMM

ECC

• Type
  • Unbuffered = Unregistered = UDIMM = Synchronous DRAM = SDRAM
  • Registered = RDIMM
• Unbuffered platform cannot use registered RAM
• But Registered platform can use Unbuffered RAM

Software

Linux

• Install i2c-tools
• Try decode-dimms
