  2. RAM limit - Wikipedia

    en.wikipedia.org/wiki/RAM_limit

    The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system.

  3. DDR3 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR3_SDRAM

    As with earlier memory generations, faster DDR3 memory became available after the release of the initial versions. DDR3-2000 memory with 9-9-9-28 latency (9 ns) was available in time to coincide with the Intel Core i7 release in late 2008, [ 19 ] while later developments made DDR3-2400 widely available (with CL 9–12 cycles = 7.5–10 ns), and ...

  4. Random-access memory - Wikipedia

    en.wikipedia.org/wiki/Random-access_memory

    A 64 bit memory chip die, the SP95 Phase 2 buffer memory produced at IBM mid-1960s, versus memory core iron rings 8GB DDR3 RAM stick with a white heatsink Random-access memory ( RAM ; / r æ m / ) is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code .

  5. DDR4 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR4_SDRAM

    DDR4 is not compatible with any earlier type of random-access memory (RAM) due to different signaling voltage and physical interface, besides other factors. DDR4 SDRAM was released to the public market in Q2 2014, focusing on ECC memory , [ 6 ] while the non-ECC DDR4 modules became available in Q3 2014, accompanying the launch of Haswell-E ...

  6. Synchronous dynamic random-access memory - Wikipedia

    en.wikipedia.org/wiki/Synchronous_dynamic_random...

    DDR3 memory chips are being made commercially, [11] and computer systems using them were available from the second half of 2007, [12] with significant usage from 2008 onwards. [13] Initial clock rates were 400 and 533 MHz, which are described as DDR3-800 and DDR3-1066 (PC3-6400 and PC3-8500 modules), but 667 and 800 MHz, described as DDR3-1333 ...

  7. DIMM - Wikipedia

    en.wikipedia.org/wiki/DIMM

    A DIMM (Dual In-Line Memory Module) is a popular type of memory module used in computers. It is a printed circuit board with one or both sides (front and back) holding DRAM chips and pins . [ 1 ] The vast majority of DIMMs are manufactured in compliance with JEDEC memory standards , although there are proprietary DIMMs.

  8. DDR2 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR2_SDRAM

    Thus, DDR2 memory must be operated at twice the data rate to achieve the same latency. Another cost of the increased bandwidth is the requirement that the chips are packaged in a more expensive and difficult to assemble BGA package as compared to the TSSOP package of the previous memory generations such as DDR SDRAM and SDR SDRAM. This ...

  9. DDR5 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR5_SDRAM

    Double Data Rate 5 Synchronous Dynamic Random-Access Memory (DDR5 SDRAM) is a type of synchronous dynamic random-access memory. Compared to its predecessor DDR4 SDRAM , DDR5 was planned to reduce power consumption, while doubling bandwidth . [ 5 ]
