LGA1248 dual-socket motherboards are scarce primarily due to the limited market demand for such configurations, as most enterprise applications do not require dual-socket setups for the LGA1248 architecture. Additionally, the LGA1248 socket is designed primarily for specific Intel Xeon processors, which may not be as popular in dual-socket configurations compared to other socket types like LGA2011 or LGA3647. Manufacturers may also prioritize producing single-socket motherboards, which are often sufficient for most workloads, leading to a lack of dual-socket options for the LGA1248.
LGA775, LGA1155, and LGA1366 are the most common Intel sockets. However there are several more still being used, and some that Intel has just recently released; such as LGA1156, LGA2011, LGA1248, and LGA1567.
MoBo is the only abbreviation i know of.
The three speeds of the most popular motherboards currently available on the market are, 1066 Mhz, 800 Mhz, and 533 Mhz
You cannot do that. At least not with commercially available ones.
Most probably ASUSTek, Gigabyte, EVGA, or intel.
533mhz 800mhz 1066mhz 1333mhz
1066 MHz, 800 MHz, 533MHz and 400 MHz are the most popular speeds of motherboards that support Intel processors.
Find your motherboards' vendor and look them up there. They are only available through OEM's and not from Marvell directly.
Many motherboards from companies such as Gigabyte, microstar and intel feature 1 year warranties.
what are the four speeds of the most popular motherboards currently available on the market that support Intel processors There is no such identifier as speed when referring to motherboards. They are classed as AMD or INTEL, socket type, memory type, size. The four speeds are 1600, 1333, 1066, or 800 MHz.
10 motherboards
If you mean "how many models of motherboards" - thousands. If you mean "how many pieces of motherboards" - probably billions.
