Socket AM2
The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors), is a CPU socket designed by AMD for desktop processors, including the performance, mainstream and value segments. It was released on May 23, 2006, as a replacement for Socket 939. Technical specifications AM2 processors are incompatible with 939 motherboards and vice versa, and although it has 940 pins, it is incompatible with Socket 940. Socket AM2 supports DDR2 SDRAM memory but not DDR memory, which the previous Socket 939 supported. ''AnandTech'' reported that Socket AM2 system performance was only about 7% faster than Socket 939 equivalents, with most applications about 2% faster, despite having over 30% greater memory bandwidth due to DDR2 support. The first processor cores to support socket AM2 were the single-core Orleans (Athlon 64) and Manila (Sempron), and the dual-core Windsor ( Athlon 64 X2 and Athlon 64 FX). Most processors on Socket AM2 include SSE3 instructions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DDR2 SDRAM
Double Data Rate 2 Synchronous Dynamic Random-Access Memory (DDR2 SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) interface. It is a JEDEC standard (JESD79-2); first published in September 2003. DDR2 succeeded the original DDR SDRAM specification, and was itself succeeded by DDR3 SDRAM in 2007. DDR2 DIMMs are neither forward compatible with DDR3 nor backward compatible with DDR. In addition to double pumping the data bus as in DDR SDRAM (transferring data on the rising and falling edges of the bus clock signal), DDR2 allows higher bus speed and requires lower power by running the internal clock at half the speed of the data bus. The two factors combine to produce a total of four data transfers per internal clock cycle. Since the DDR2 internal clock runs at half the DDR external clock rate, DDR2 memory operating at the same external data bus clock rate as DDR results in DDR2 being able to provide the same bandwidth but with better la ...

DDR3 SDRAM
Double Data Rate 3 Synchronous Dynamic Random-Access Memory (DDR3 SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) with a high bandwidth (" double data rate") interface, and has been in use since 2007. It is the higher-speed successor to DDR and DDR2 and predecessor to DDR4 synchronous dynamic random-access memory (SDRAM) chips. DDR3 SDRAM is neither forward nor backward compatible with any earlier type of random-access memory (RAM) because of different signaling voltages, timings, and other factors. DDR3 is a DRAM interface specification. The actual DRAM arrays that store the data are similar to earlier types, with similar performance. The primary benefit of DDR3 SDRAM over its immediate predecessor DDR2 SDRAM, is its ability to transfer data at twice the rate (eight times the speed of its internal memory arrays), enabling higher bandwidth or peak data rates. The DDR3 standard permits DRAM chip capacities of up to 8 gigabits (Gbit) (so 1 gigabyte by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BIOS
In computing, BIOS (, ; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). The firmware comes pre-installed on the computer's motherboard. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS firmware was originally proprietary to the IBM PC; it was reverse engineered by some companies (such as Phoenix Technologies) looking to create compatible systems. The interface of that original system serves as a ''de facto'' standard. The BIOS in older PCs initializes and tests the system hardware components ( power-on self-test or POST for short), and loads a boot loader from a mass storage device which then initializes a kernel. In the era of DOS, the BIOS provided BIOS interrupt calls for the keyboard, display, st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Socket FM2
Socket FM2 is a CPU socket used by AMD's desktop ''Trinity'' and ''Richland'' APUs to connect to the motherboard as well as Athlon X2 and Athlon X4 processors based on them. FM2 was launched on September 27, 2012. Motherboards which feature the at the time new FM2 CPU socket also utilize AMD's at the time new A85X chipset. The socket is very similar to FM1, based on a 31 × 31 grid of pins with a 5 × 7 central void, three pins missing from each corner, and a few additional key pins missing. Compared to Socket FM1, two key pins were moved, and one more is removed, leaving 904 pins. For available chipsets consult Fusion controller hubs (FCH). Steamroller-based "Kaveri" APUs are ''not'' supported, see Socket FM2+ (FM2r2) and Socket FP3 (BGA-???). Heatsink The four holes for fastening the heatsink to the motherboard are placed in a rectangle with lateral lengths of 48 mm and 96 mm for AMD's sockets Socket AM2, Socket AM2+, Socket AM3, Socket AM3 ...

Socket AM3+
Socket AM3+ is a modification of Socket AM3, which was released on February 9, 2009. AM3+ was released in mid-2011 designed for CPUs which use the AMD Bulldozer (processor), Bulldozer microarchitecture and retains compatibility with processors made for AM3. The Piledriver (microarchitecture), Vishera line of AMD CPUs also all use Socket AM3+. It is the last AMD socket for which Windows XP support officially exists. Technical specifications The AM3+ Socket specification contains a few noteworthy design changes over its AM3 predecessor. The 942 pin count for the AM3+ is an increase of one compared to the AM3 Socket layout. The AM3+ Socket has larger pin socket diameter of 0.51 millimeter, mm compared to 0.45 mm with the AM3 Socket. There is a faster serial link of 3400 kHz from the CPU to the power controller, compared to 400 kHz. The AM3+ Socket offers improved power regulation and power quality specifications, including an increased maximum current support of 14 ...
