Some manufacturers also round to a certain precision or round up instead. In other projects Wikimedia Commons. DDRDand capacity variants, modules can be one of the following:. Bandwidth is calculated by taking transfers per second and multiplying by eight. This page was last edited on 17 Novemberat Devices that require DDR3L, which operate at 1. Retrieved 12 October Spwcification is some improvement because DDR3 generally uses more recent manufacturing processes, but this is not directly caused by the change to DDR3.

It is also misleading because various memory timings are given in units of clock cycles, which are half the speed of data transfers. Memory standards on the way”.

For the graphics memory, see GDDR3. Archived from the original on April 13, This reduction comes from the difference in supply voltages: Of these non-standard specifications, the highest reported speed reached was equivalent to DDR, as of May As with earlier memory generations, faster DDR3 memory became available after the release of the initial versions.

Dynamic random-access memory DRAM. It is typically used during the power-on self-test for automatic configuration of memory modules.

DDR3 SDRAM

The actual DRAM arrays that store the data are similar to earlier types, jeec similar performance. DDR3 memory utilises serial presence detect. Archived from the original PDF on This article is about the computer main memory.

Archived from the original on From Wikipedia, the free encyclopedia.

Retrieved 12 December Retrieved 19 March Under this convention PC is listed as PC Views Read Edit View history. DDR3 modules are often incorrectly labeled with the prefix PC instead of PC3for marketing reasons, followed by the data-rate.

Not only are they keyed differently, but DDR2 has rounded notches on the side and the DDR3 modules have square notches on the side.

DDR3 prototypes were announced in early Because the hertz is a measure of cycles per second, and no signal cycles more often than every other transfer, describing the transfer rate in units of MHz is technically incorrect, although very common. Retrieved from ” https: The DDR3L standard is 1. This advantage is an enabling technology in DDR3’s transfer speed.

High-performance graphics was an initial jedrc of such bandwidth requirements, where high bandwidth data transfer between framebuffers is required.

All articles with unsourced statements Articles with unsourced statements from March The CPU’s integrated memory controller can then work with either. In addition to bandwidth designations e. The Core i7 supports only DDR3.
