The chipsets contain a 'memory controller hub' and an 'I/O controller hub', which tend to be called 'north bridge' and 'south bridge' respectively. The memory controller hub connects to the processors, memory, high-speed I/O such as PCI Express, and to the I/O controller hub by a proprietary link.
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
There is much confusion between registered and ECC memory; it is widely thought that ECC memory (which may or may not be registered) will not work at all in a motherboard without ECC support, not even without providing the ECC functionality, although the compatibility issues actually arise when trying to use registered memory (which often ...
The MRC is part of reference BIOS code, which relates to memory initialization in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced ...
Some small Chinese manufacturers are producing LGA 1156 motherboards based on H61 chipset, and ASRock, for very short time, produced LGA 1156 motherboard based on P67 chipset, the P67 Transformer. It exclusively supports Lynnfield processors and was discontinued after B2 revision of 6 series chipsets was recalled , not receiving a version with ...
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.
Microcontroller devices with integrated I/O and memory on-chip sometimes had no, or a small, address bus available for external devices. For example, a microcontroller family available with a 2 kilobyte address space might have a variant that brought out an 11 line address bus for an external ROM; this could be done by reassigning I/O pins as address bus pins.
As a significant new feature, the X99 enthusiast platform as a whole was the first to support DDR4 memory. Thanks to the features of integrated memory controllers (IMCs) of supported processors, the X99 platform also supports dual-and quad-channel memory layouts, with optional support for registered ECC memory.
