Know Your RAM

RAM (Random Access Memory) is one of the primary memories for computers. RAM location is adjacent to the processor. RAM serves to hold the landing and data to be processed by the processor. RAM is volatile, namely mean data stored by the RAM is lost when the computer is turned off.
As an example of the usefulness of RAM, when you open this blog, your computer’s RAM is filled with data describing this blog. However, It was going to disappear from the RAM if the computer is turned off (therefore we need the storage for data storage purposes).
various kinds of RAM is available in the market is Kingston, Corsair, Hynix, Apacer and others again




The types of RAM

EDO RAM (Enhanced Data Output RAM)

• Must be installed in pairs
• 1 notch (groove on the foot of RAM)
• Used on older machines (90s)

RDRAM RAM (Rambus Dynamic RAM)

• 232-pin
• There’s a heatsink (a special cooling system)
• Must be installed in pairs
• Used on the old computer (1999, 2000, …)

SDRAM RAM (Synchronous Dynamic RAM)

• 168 pin
• 2 notch
• Speed​​: 100MHz, 133MHz
• Maximum Capacity: 512

DDR RAM (Double Data Rate RAM)

• 184 pin
• 1 notch
• speed: 266MHz (PC2100), 333MHz (PC2700), 400MHz (PC3200)
• Kapasiti Maximum: 1GB (there is a layer of chips on the front and rear of RAM)

DDR II

• 240 pin
• 1 notch (but different from the DDR, the hole notch to the left a bit)
• Speed​​: 533MHz (PC4200), 667MHz (PC5300), 800MHz (PC6400)
• Maximum Capacity: 2GB

DDR III

• 240 pin
• 1 notch (but different from the DDR and DDR2, the hole more notch to the left again)
• Speed​​: 1333MHz (PC10666), …
• Maximum Capacity: 4GB

SODIMM (Small Outline Dual Inline Memory Module) is a RAM for notebook / laptop.




SIMM (Single In-line Memory Module) refers to the old RAM, for example, EDO RAM RAM that has only one leg who is active (working). SIMM is have 30 pins or 72 pins. SIMM 30 pin requires 4 pieces of RAM installed on the motherboard while the SIMM 72 pin requires at least two pieces of RAM installed on the motherboard.




DIMM (Dual In-line Memory Module) refers to last more RAM than SIMMs, such as DDR RAM RAM module in which both surfaces are active (working). DIMMs have 168 pins (84 x 2) and only requires a piece of RAM just to operate.
