A 16GB [1] DDR4 SO-DIMM module by Micron. DDR4 memory is supplied in 288-pin dual in-line memory modules (DIMMs), similar in size to 240-pin DDR3 DIMMs. DDR4 RAM modules feature pins that are spaced more closely at 0.85 mm compared to the 1.0 mm spacing in DDR3, allowing for a higher pin density within the same standard DIMM length of 133.35 mm ...
It comes with a variety of "high-end" options such as Intel Xeon E3-1500M v5 processors, 4K IPS screens and DDR4 ECC RAM up to 64 GB. 1080p screens and 6th generation Core CPUs come standard along with PCI Express SSDs. The P series introduced a cooling system known as FLEX (Full Load Experience) that features two fans connected by a heat pipe ...
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 banks for each bank group for ×16 DRAM. The DDR4 SDRAM uses an 8n prefetch architecture to achieve high-speed
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.
Rather than working exclusively with DDR4, the Skylake microarchitecture remains backward compatible by interoperating with both types of memory. Accompanying the microarchitecture's support for both memory standards, a new SO-DIMM type capable of carrying either DDR3 or DDR4 memory chips, called UniDIMM , was also announced.
The separate JEDEC standard Low Power Double Data Rate 5 (LPDDR5), intended for laptops and smartphones, was released in February 2019. [15] Compared to DDR4, DDR5 further reduces memory voltage to 1.1 V, thus reducing power consumption. DDR5 modules incorporate on-board voltage regulators in order to reach higher speeds.
DDR4 reached mass market adoption around 2015, which is comparable with the approximately five years taken for DDR3 to achieve mass market transition over DDR2. The DDR4 chips run at 1.2 V or less, [18] [19] compared to the 1.5 V of DDR3 chips, and have in excess of 2 billion data transfers per second.
The desktop contained an AMD Athlon II X4 640 processor, 4 GB of DDR3 RAM, a 500 GB hard disk drive, and ATI Radeon HD 3000 discrete graphics. [27] The desktop was indicated by Lenovo to be "multi-monitor friendly", with the capacity to power two displays even with the basic configuration. [ 27 ]
