The maximum speed of DDR3 RAM is defined by its data transfer rate, typically measured in megatransfers per second (MT/s), and its clock frequency. Here's a breakdown of the fastest DDR3 specifications:

What is the maximum speed of the DDR3 RAM? |
Maximum Speed of DDR3 RAM:
- The fastest official DDR3 specification is DDR3-2133, which operates at a data transfer rate of 2133 MT/s (megatransfers per second).
- This corresponds to a clock frequency of 1066 MHz (since DDR3 is "double data rate," it transfers data twice per clock cycle).
Additional Information:
- DDR3-2133 can achieve a peak bandwidth of 17,066 MB/s per channel, assuming a 64-bit wide memory bus.
- Some manufacturers have developed overclocked DDR3 modules that exceed this standard speed, reaching up to DDR3-2400 (2400 MT/s), but these are not part of the official JEDEC (Joint Electron Device Engineering Council) DDR3 specification.
In summary, the maximum official speed of DDR3 RAM is 2133 MT/s, although higher speeds, such as DDR3-2400, exist in overclocked modules.
