RAM Flashcards
SIMM
Single Inline Memory Module
DRAM
Dynamic Random Access Memory
Modern DRAM Bits
32 bit and 64 bit
SDRAM
Synchronous Dynamic Random Access Memory, tied to system clock
DIMM
Dual Inline Memory Module
Laptop DIMMs
Micro-DIMM
Small-Outline DIMM (SODIMM)
DDR Ram
Double Data Rate, very fast
Dual Channel Architecture
Using two sticks to increase throughput
Current RAM Speeds
DDR3/4/5
DDR3
240 Pin
SO DIMM 204 pin
8 bit bandwidth buffer
Extreme Memory Profile (XMP) to overclock
Max 16 GB
Triple or Quad Channel sometimes
I/O is quadruple clock
Speed is double I/O
PC Speed is 8x speed
DDR4
Higher density and lower voltage than 3, faster data rates
288 pin
SO-DIMM 204 pin
Max 64GB
I/O is x8 clock
I/O = Speed
PC is 8x speed
DDR5
Includes Power Management Integrated Circuit to deal with power management rather than mb
288 pin
SODIMM 262 pin
Max 256GB
Bandwidth and Speed = Clock x8
PC=Speed x8
Double-sided RAM
basically two sticks of RAM smacked together, some mb can’t use
RAM Latency
Delay in response time
RAM for Techs
Make sure the RAM latency matches the needs of the mb
