Version 3.2, published on July 23, 2013, raised the data rate to 533 MB/s. [15] Version 4.0, published on April 17, 2014, introduced the NV-DDR3 interface increases the maximum switching speed from 533 MB/s to 800 MB/s, providing a performance boost of up to 50% for high performance applications enabled by solid-state NAND storage components.

In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
Compared to DDR2 memory, DDR3 memory uses less power. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current. [10]According to JEDEC, [11]: 111 1.575 volts should be considered the absolute maximum when memory stability is the foremost consideration, such as in servers or other mission-critical devices.
Assorted SO-DIMM Modules A 200-pin PC2-5300 DDR2 SO-DIMM. A 204-pin PC3-10600 DDR3 SO-DIMM. A SO-DIMM slot on a computer motherboard. A SO-DIMM (pronounced "so-dimm" / ˈ s oʊ d ɪ m /, also spelled "SODIMM") or small outline DIMM, is a smaller alternative to a DIMM, being roughly half the physical size of a regular DIMM. The first SODIMMs had ...
An "enhanced" version of the specification called LPDDR3E increases the data rate to 2133 MT/s. Samsung Electronics introduced the first 4 gigabit 20 nm-class LPDDR3 modules capable of transmitting data at up to 2,133 MT/s, more than double the performance of the older LPDDR2 which is only capable of 800 MT/s.

DDR3 advances extended the ability to preserve internal clock rates while providing higher effective transfer rates by again doubling the prefetch depth. The DDR4 SDRAM is a high-speed dynamic random-access memory internally configured as 16 banks, 4 bank groups with 4 banks for each bank group for ×4/×8 and 8 banks, 2 bank groups with 4 ...

A version of P35 with an ICH7 South Bridge, supports only 4 GB of DDR2 memory and does not support DDR3 memory. Operational configuration is 4 ranks - 2× 2 GB dual rank modules or 4 × 1 GB single rank modules - depends on number of motherboard DDR2 slots. 4GBs modules are not supported.
