Memory Modules Flashcards
Most modern motherboards that you can put any-size module in any slot.
Single Bank
Older mother boards that required installation of banks in pairs.
Paired Bank
Most common type of memory that is going to be used in most systems?
DDR Dual Data Rate
What type of memory commonly has 240 or 184 pin connector?
(DIMM) Dual Inline Memory Module
Most modern systems calculated based on the bus speed and the width of the data bus.
Throughput
The oldest type of memory that requires frequent refreshing.
Dynamic Ram (DRAM)
Solved issue of constant refresh, but expensive.
Static Ram (SRAM)
The first memory module that operates at the same speed as the motherboard (168-pin connector)
Synchronous DRAM (SDRAM)
How many MHz did the PC66, PC133 and PC266 operate in?
66 MHz bus
133 MHz bus
266 MHz bus
What doubled the speed of an SRAM module (184 pin)
Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM)
Memory module that has higher latency and has faster access to the internal bus (240 pin connector)
Double Data Rate 2 Synchronous Dynamic Random-Access Memory (DDR2-SDRAM)
Memory module that would be labeled PC2-4200 with speeds of 4.2 GB/s
DDR2 SDRAM
Runs at a lower voltage and higher speed then DDR2 (240 keyed pin connector)
Double Data Rate 3 Synchronous Dynamic Random Access Memory (DDR3 SDRAM)
Memory module that would be labeled as PC3-10600. With speeds of 10.6 GB/s
DDR3 SDRAM
Why should you buy modules in pairs with the same brand, speed and throughput?
Because if you have two different speed modules the faster on will be lowered to match the speed of the slower module.
