Socket STR5
Socket sTR5 is a land grid array (LGA) CPU socket designed by AMD. It supports the Zen 4-based Ryzen Threadripper 7000 series, which launched in November 2023. Details sTR5 is a socket for both ''Ryzen Threadripper'' HEDT and ''Ryzen Threadripper Pro'' workstation processor lineups. This is unlike the preceding (3000 and 5000 series) generations of Ryzen Threadripper / Threadripper Pro processors, which were on separate sockets, sTRX4 and sWRX8 respectively. The sTR5 socket has two chipsets available: TRX50 for HEDT consumer systems, and WRX90 for professional workstation systems. TRX50 supports both Threadripper and Threadripper PRO CPU models, while WRX90 supports only Threadripper Pro models. Socket sTR5 supports DDR5 memory of the RDIMM type with ECC, as well as PCIe 5.0. It does not support non-registered DIMMs, non-ECC RAM, or DDR4. The maximum number of memory channels is 8 and the maximum number of PCIe 5.0 lanes is 128 with a Threadripper PRO CPU and a WRX90 ...

Land Grid Array
The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket (when a socket is used) — as opposed to pins on the integrated circuit, known as a '' pin grid array'' (PGA). An LGA can be electrically connected to a printed circuit board (PCB) either by the use of a socket or by soldering directly to the board. Description The ''land grid array'' is a packaging technology with a grid of contacts, 'lands', on the underside of a package. The contacts are to be connected to a grid of contacts on the PCB. Not all rows and columns of the grid need to be used. The contacts can either be connected by using an LGA socket, or by surface-mount soldering using solder paste. The grid elements found in use can be e.g. circular, triangular or other polygonal shapes and might have even different sizes. Grids might sometimes appear like honey comb patterns. Designs are often optimized for factors like contact likelin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AnandTech
''AnandTech'' was an online computer hardware magazine owned by Future plc. It was founded in April 1997 by then-14-year-old Anand Lal Shimpi, who was CEO and editor-in-chief until August 2014, with Ryan Smith replacing him as editor-in-chief. The website was a source of hardware reviews for off-the-shelf components and exhaustive benchmarking, targeted towards computer-building enthusiasts, but later expanded to cover mobile devices such as smartphones and tablets. Some of their articles on mass-market products such as mobile phones were syndicated by CNNMoney. The large accompanying forum is recommended by some books for bargain hunting in the technology field. AnandTech was acquired by Purch on 17 December 2014. Purch was acquired by Future in 2018. On August 30, 2024, the publication shut down. The content of the website was said to be preserved, but no new articles or reviews would be published. The AnandTech forums would continue to operate.

Socket SWRX8
Socket sWRX8, also known as ''Socket SP3r4'', is a land grid array (LGA) CPU socket designed by AMD supporting its Ryzen Threadripper Pro 3000 and 5000 series workstation processors, which are based on Zen 2 and Zen 3 platforms, respectively. It was initially launched in July 2020 for OEMs only, with retail availability coming later in March 2021. Socket sWRX8 does not succeed any previous sockets; instead it sits alongside socket sTRX4 as a socket for professional workstation computers, while sTRX4 is for consumer high-end desktop (HEDT) computers. sWRX8 has support for octa-channel DDR4 memory and 128 PCIe 4.0 lanes from the CPU, whereas sTRX4 only supports quad-channel DDR4 and 64 PCIe 4.0 lanes. Furthermore, unlike sTRX4, it supports RDIMM, LRDIMM and 3DS RDIMM memory types, allowing up to 2TB of RAM to be installed (compared to the maximum of 256GB for sTRX4). It is physically identical to, but electrically incompatible with both sTRX4 and AMD's server socket SP3. While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PCIe 5
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe, is a high-speed standard used to connect hardware components inside computers. It is designed to replace older expansion bus standards such as PCI, PCI-X and AGP. Developed and maintained by the PCI-SIG (PCI Special Interest Group), PCIe is commonly used to connect graphics cards, sound cards, Wi-Fi and Ethernet adapters, and storage devices such as solid-state drives and hard disk drives. Compared to earlier standards, PCIe supports faster data transfer, uses fewer pins, takes up less space, and allows devices to be added or removed while the computer is running (hot swapping). It also includes better error detection and supports newer features like I/O virtualization for advanced computing needs. PCIe connections are made through "lanes," which are pairs of wires that send and receive data. Devices can use one or more lanes depending on how much data they need to transfer. PCIe techn ...

Error Correcting Code
In computing, telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels. The central idea is that the sender encodes the message in a redundant way, most often by using an error correction code, or error correcting code (ECC). The redundancy allows the receiver not only to detect errors that may occur anywhere in the message, but often to correct a limited number of errors. Therefore a reverse channel to request re-transmission may not be needed. The cost is a fixed, higher forward channel bandwidth. The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. FEC can be applied in situations where re-transmissions are costly or impossible, such as one-way communication links or when transmitting to multiple receivers in m ...

RDIMM
Registered memory (also called buffered memory) is computer memory that has a register between the DRAM modules and the system's memory controller. A registered memory module places less electrical load on a memory controller than an unregistered one. Registered memory allows a computer system to remain stable with more memory modules than it would have otherwise. When conventional memory is compared with registered memory, conventional memory is usually referred to as unbuffered memory or unregistered memory. When registered memory is manufactured as a dual in-line memory module (DIMM), it is called an RDIMM. Similarly, an unregistered DIMM is called a UDIMM or simply "DIMM". Registered memory is often more expensive because of the additional circuitry required and lower number of units sold, so it is usually found only in applications where the need for scalability and robustness outweighs the need for a low price for example, registered memory is usually used in servers. ...

DDR5
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. The standard, originally targeted for 2018, was released on July 14, 2020. A new feature called Decision Feedback Equalization (DFE) enables input/output (I/O) speed scalability for higher bandwidth and performance improvement. DDR5 has about the same latency as DDR4 and DDR3. DDR5 octuples the maximum DIMM capacity from 64 GB to 512 GB. DDR5 also has higher frequencies than DDR4, up to 9600 MT/s is currently possible, 8200 MT/s translates into around 66 GB/s of bandwidth. Using liquid nitrogen 13000 MT/s speeds were achieved. Rambus announced a working DDR5 dual in-line memory module (DIMM) in September 2017. On November 15, 2018, SK Hynix announced completion of its first DDR5 RAM chip; running at 5.2 GT/s at 1.1 V. ...

CPU Socket
In computer hardware, a CPU socket or CPU slot contains one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows for placing and replacing the central processing unit (CPU) without soldering. Common sockets have retention clips that apply a constant force, which must be overcome when a device is inserted. For chips with many pins, zero insertion force (ZIF) sockets are preferred. Common sockets include pin grid array (PGA) or land grid array (LGA). These designs apply a compression force once either a handle (PGA type) or a surface plate (LGA type) is put into place. This provides superior mechanical retention while avoiding the risk of bending pins when inserting the chip into the socket. Certain devices use Ball Grid Array (BGA) sockets, although these require soldering and are generally not considered user replaceable. CPU sockets are used on the motherboard in desktop and ...
