Product Information

Addendum No. 2 to JESD79-3, 1.25 V DDR3U-800, DDR3U-1066, DDR3U-1333, and DDR3U-1600". October 2011 . Retrieved 2019-09-08.

Alternative naming: DDR3 modules are often incorrectly labeled with the prefix PC (instead of PC3), for marketing reasons, followed by the data-rate. Under this convention PC3-10600 is listed as PC1333. [25] Serial presence detect [ edit ] a b "What is LR-DIMM, LRDIMM Memory? (Load-Reduce DIMM)". simmtester.com.

Intel Corporation officially introduced the eXtreme Memory Profile ( XMP) Specification on March 23, 2007, to enable enthusiast performance extensions to the traditional JEDEC SPD specifications for DDR3 SDRAM. [28] Variants [ edit ]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: Frequently Asked Questions" (PDF).

Release 4 of the DDR3 Serial Presence Detect (SPD) document (SPD4_01_02_11) adds support for Load Reduction DIMMs and also for 16b-SO-DIMMs and 32b-SO-DIMMs.

Soderstrom, Thomas (2007-06-05). "Pipe Dreams: Six P35-DDR3 Motherboards Compared". Tom's Hardware. Compared to DDR2 memory, DDR3 memory uses less power. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current. [10] DDR3 does use the same electric signaling standard as DDR and DDR2, Stub Series Terminated Logic, albeit at different timings and voltages. Specifically, DDR3 uses SSTL_15. [13] 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. [17]Fully buffered modules, which are designated by F or FB and do not have the same notch position as other classes. Fully buffered modules cannot be used with motherboards that are made for registered modules, and the different notch position physically prevents their insertion.
