Theoretical Capacity Of Ddr4 4,9/5 8658 reviews
There’s 16GB of capacity, and the Ballistix Sport rattles along at 2666MHz – right in the middle of the range of DDR4 speeds, and fast enough to ensure that this DDR4 doesn’t lose much. Additionally, the maximum theoretical capacity of DDR4 is a whopping 512GB! Wow, imaging having that much RAM in your computer. Also, DDR4 will be more power efficient. It will utilize 1.2V for I/O compared to DDR3L, which utilizes 1.35V. In addition, DDR4 also brings improved reliability, availability and serviceability (RAS).
Theoretical Capacity Of A Ddr4
DDR4 SDRAM is the abbreviation for 'Double Data Rate fourth generation synchronous dynamic random-access memory', the latest variant of memory in computing.
There are a lot of deeply technical aspects to DDR4, but I won’t dive that far. The two key improvements in DDR4 are power consumption and data transfer speed, thanks to the development of an all-new bus.
From Cruicial
DDR3 generally requires 1.5 volts of electrical power to operate. DDR4 needs 20 percent less—just 1.2 volts. DDR4 also supports a new, deep power-down mode that will allow the host device to go into standby without needing to refresh its memory. Deep power-down mode is expected to reduce standby power consumption by 40- to 50 percent.
DDR4 chips support transfer rates between 2133 MT/s (million transfers per second) and 4266 MT/s. By comparison, DDR3 technology supports only up to 800 to 2133 MT/s. They have higher latency when compared to DDR3 due to the higher operating frequency.
(288 pins in DDR4's case vs. 240 in DDR3 in desktop size DIMMs). Also note the slightly curved shape of the connector (which gets deeper at the middle), which is another difference.)
Finally, DDR4 uses much higher-density chips, so each memory stick (DIMM, technically) will pack a lot more memory.The DDR4 standard theoretically allows for DIMMs of up to 512 GB in capacity, compared to the DDR3's theoretical maximum of 128 GB per DIMM.
Some tech unaware people had asked me 'why they naming it DDR4 when GDDR5 is there? '.
Answer:
GDDR5 RAM is a graphics type of DDR3 RAM, which was introduced before DDR4, and is not a successor to DDR4.
