The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2] Many or most Xeons subsequent to this support VT-d.
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).
The E7320, E7520 and E7525 chipsets correspond to Prescott-based Pentium4 Xeons, and differ mainly in their PCI Express support. These support Socket 604. The Intel 875P chipset was used in some two-socket motherboards for Xeons. [8] [9] [10] [11]
System Management Bus (SMBus) is also provided, with additional support for I 2 C devices. [1] [2]: 4–10 [8] [9] Overclocking is available for unlocked variants of the supported processors. As a significant new feature, the X99 enthusiast platform as a whole was the first to support DDR4 memory.
Most motherboards with the LGA 1150 socket support varying video outputs (VGA, DVI or HDMI – depending on the model) and Intel Clear Video Technology. Full support of Windows on LGA 1150 platform starts on Windows 7. Official Windows XP support is limited to selected CPUs, chipsets and only for embedded and industrial systems.
Some motherboards using the 945 chipset could be given a BIOS upgrade to support 65nm Core-based processors. Other chipsets have varying levels of CPU support, generally following the release of contemporary CPUs, as LGA 775 CPU support is a complicated mixture of chipset capability, voltage regulator limitations and BIOS support.
LGA 1200 is a land grid array mount with 1200 protruding pins to make contact with the pads on the processor. It uses a modified design of LGA 1151, with 49 more pins on it, improving power delivery and offering support for future incremental I/O features.
LGA 2066, also called Socket R4, is a CPU socket by Intel that debuted with Skylake-X and Kaby Lake-X processors in June 2017. [1] It replaces Intel's LGA 2011-3 (R3) in the performance, high-end desktop and Workstation platforms (based on the X299 "Basin Falls" and C422 chipsets), while LGA 3647 (Socket P) replaces LGA 2011-3 (R3) in the server platforms based on Skylake-SP (Xeon "Purley").
