DDR3 memory has how many pins
240 pin. notch left to center
RAM that operates at 1.2 volts at bus frequencies between 1066-2133 MHz.
DDR4
The internal memory frequency of DDR4 is ?
one-tenth the bus frequency
DDR4 memory has how many pins
288 pin notch slight right of center
RAM that has pins on both sides of the module is called
DIMM
DIMMs capacity is
512 GB
smaller DIMM used in laptops.
SODIMM
SODIMM 144 pin is used by which types of RAM
SDRAM, DDR and DDR2
SODIMM 200 Pin is used by which types of RAM
DDR2 and DDR3
a specification for DIMMs and is designed to carry DRAM chips.
UniDIMM
UniDIMM is used by with types of RAM
DDR3 and DDR4
DIMM is used with
DDR4
what is the MHz to PC designation formula?
MHz= 2 times bus frequency and MHz =16 times frequency
so 100 MHz = PC 200 and
100 MHz = PC 1600
what the MHz to DDR designation formula?
MHz = 2 times bus frequency
