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.
Some ECC-enabled boards and processors are able to support unbuffered (unregistered) ECC, but will also work with non-ECC memory; system firmware enables ECC functionality if ECC memory is installed. ECC may lower memory performance by around 2–3 percent on some systems, depending on the application and implementation, due to the additional ...
Higher end version of 915. Supports another PAT-like mode and ECC memory, and exclusively uses DDR-II RAM. Sub-versions: 925XE - Supports a 1066 MT/s bus. 945P (Lakeport) Update on 915P, with support for Serial ATA II, RAID mode 5, an improved memory controller with support for DDR-II at 667 MHz and additional PCI Express lanes.
Intel X99, codenamed "Wellsburg", is a Platform Controller Hub (PCH) designed and manufactured by Intel, targeted at the high-end desktop (HEDT) and enthusiast segments of the Intel product lineup. [ 2 ] : 10 The X99 chipset supports both Intel Core i7 Extreme and Intel Xeon E5-16xx v3 and E5-26xx v3 processors , which belong to the Haswell-E ...
Integrated memory controller supporting three memory channels of DDR3 memory with ECC support. A new point-to-point processor interconnect QuickPath, replacing the legacy front side bus. Gainestown has two QuickPath interfaces. Hyper-threading (2× per core, starting from 5518), that was already present in NetBurst-based processors
DDR3L/LPDDR3/LPDDR4 dual-channel memory controller supporting up to 8 GB; support for DDR3L with ECC; Display controller with 1 MIPI DSI port and 2 DDI ports (eDP 1.3, DP 1.1a, or HDMI 1.4b) Integrated Intel HD Graphics (Gen9) GPU; PCI Express 2.0 controller supporting 6 lanes (3 dedicated and 3 multiplexed with USB 3.0); 4 lanes available ...
Hence, an ECC memory can support the scrubbing of the memory content. Namely, if the memory controller scans systematically through the memory, the single bit errors can be detected, the erroneous bit can be determined using the ECC checksum , and the corrected data can be written back to the memory.
One 64 GiB DDR5-4800 ECC 1.1 V registered DIMM (RDIMM) Example of an unregistered DIMM (UDIMM) 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.
