JEDEC is already well along in the development of the DDR3 standard, and we have been working on it for about three years now.... Following historical models, you could reasonably expect the same three-year transition to a new technology that you have seen for the last several generations of standard memory Compared to DDR2 memory, DDR3 memory uses less power. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current. [10]

Understanding DDR3 Serial Presence Detect (SPD) Table". simmtester.com . Retrieved 12 December 2015. Fractional frequencies are normally rounded down, but rounding up to 667 is common because of the exact number being 666 2⁄ 3 and rounding to the nearest whole number. Some manufacturers also round to a certain precision or round up instead. For example, PC3-10666 memory could be listed as PC3-10600 or PC3-10700.

How Intel Plans to Transition Between DDR3 and DDR4 for the Mainstream". techpowerup.com . Retrieved 19 March 2018. Both FBDIMM (fully buffered) and LRDIMM (load reduced) memory types are designed primarily to control the amount of electric current flowing to and from the memory chips at any given time. They are not compatible with registered/buffered memory, and motherboards that require them usually will not accept any other kind of memory. DDR3 dual-inline memory modules (DIMMs) have 240 pins and are electrically incompatible with DDR2. A key notch—located differently in DDR2 and DDR3 DIMMs—prevents accidentally interchanging them. Not only are they keyed differently, but DDR2 has rounded notches on the side and the DDR3 modules have square notches on the side. [16] DDR3 SO-DIMMs have 204 pins.

The DDR3L ( DDR3 Low Voltage) standard is an addendum to the JESD79-3 DDR3 Memory Device Standard specifying low voltage devices. [31] The DDR3L standard is 1.35V and has the label PC3L for its modules. Examples include DDR3L‐800 (PC3L-6400), DDR3L‐1066 (PC3L-8500), DDR3L‐1333 (PC3L-10600), and DDR3L‐1600 (PC3L-12800). Memory specified to DDR3L and DDR3U specifications is compatible with the original DDR3 standard, and can run at either the lower voltage or at 1.50 V. [32] However, devices that require DDR3L explicitly, which operate at 1.35V, such as systems using mobile versions of fourth-generation Intel Core processors, are not compatible with 1.50V DDR3 memory. [33] DDR3L is different from and incompatible with the LPDDR3 mobile memory standard. IDF: "DDR3 won't catch up with DDR2 during 2009" ". pcpro.co.uk. 19 August 2008.

DDR3-xxx denotes data transfer rate, and describes DDR chips, whereas PC3-xxxx denotes theoretical bandwidth (with the last two digits truncated), and is used to describe assembled DIMMs. Bandwidth is calculated by taking transfers per second and multiplying by eight. This is because DDR3 memory modules transfer data on a bus that is 64 data bits wide, and since a byte comprises 8 bits, this equates to 8 bytes of data per transfer. Another benefit is its prefetch buffer, which is 8-burst-deep. In contrast, the prefetch buffer of DDR2 is 4-burst-deep, and the prefetch buffer of DDR is 2-burst-deep. This advantage is an enabling technology in DDR3's transfer speed.
