An SDRAM with a high bandwidth interface is known as the DDR3 SDRAM.
Memory chips that use synchronous dynamic random access memory (SDRAM) (DDR3 and DDR2) and synchronous dynamic random access memory (SDRAM) are known as DDR3 and DDR4. DDR3 SDRAM is not compatible with any earlier random-access memory because of changing signaling voltages, timing, and other variables (RAM).
With DDR3 RAM, data may be transferred at double the rate (eight times the speed of its internal memory arrays) compared to its direct predecessor, DDR2 SDRAM, which means that peak data rates can be significantly increased.
Types of DDR3 RAM
DDR3-1066 RAM has a transfer rate of 1066 MT/s and memory clock rate of 133 MHz, hence the data rate transfer will be 8533 Mbps
DDR3-1333 RAM has a transfer rate of 1333 MT/s and memory clock rate of 167 MHz, hence the data rate transfer will be 10667 Mbps
DDR3-1600 RAM has a transfer rate of 1600 MT/s and memory clock rate of 200 MHz, hence the data rate transfer will be 12800 Mbps
DDR3-2133 RAM has a transfer rate of 2133 MT/s and memory clock rate of 267 MHz, hence the data rate transfer will be 17067 Mbps
DIMMs and SO-DIMMs are generally used in desktop PCs, whereas all-in-one computers and laptops use SO-DIMMs. The DDR3 memory modules can’t be inserted into a DDR2 RAM slot, and vice versa, because the pins are placed differently.
Dual-Inline memory Modules (DIMM) of the DDR3 RAM are also notable to have 240 pins making it not compatible with DDR2 RAM slots. We still have the greatest DDR3-2133 RAM for gaming and professional use in 2021 for people who are still using DDR3 technology in their computers. When compared to DDR2 RAM, the DDR3 RAM uses a lot less power. Supply voltage variance is the blame for this.
The voltage range of DDR3 RAM is 1.35 to 1.5 volts, while that of DDR2 RAM is 1.8 to 1.9 volts. Dual gate transistors utilized in a few DDR3 RAM models by their producers also help to prevent current leakage from them.
