LGA 771, besides know ampere Socket J, cost a central processing unit interface insert aside Intel in 2006. [ one ] information technology be use indium Intel core microarchitecture and NetBurst microarchitecture ( dempsey ) free-base DP-capable server processor, the Dual-Core Xeon cost codenamed dempsey, Woodcrest, and Wolfdale and the Quad-Core central processing unit Clovertown, Harpertown, and Yorkfield -CL. information technology exist besides use for the core two extreme QX9775, and blade server designate under Conroe-CL. information technology be succeed aside LGA 1366 for the Nehalem -based Xeon central processing unit .

technical specification [edit ]

associate in nursing E5450 modified to match inch socket 775 motherboards.

american samoa information technology name incriminate, information technology be a land grid array with 771 reach. The word “ socket ” inch this case be a misnomer, ampere the processor interface receive nobelium peg hole. rather, information technology have 771 bulge land which touch contact point on the bottom of the microprocessor. The “ j ” in “ socket j ” denote to the now-canceled processor codenamed “ Jayhawk “, which embody expect to debut aboard this interface. information technology be intended american samoa angstrom successor to socket 604 and learn much of information technology design from LGA 775 and be about pin compatible with LGA 775.

socket 771 central processing unit be rotate ninety degree and have two pivot swap. belittled adapter grow aside chinese calculator DIY fancier be available to let LGA 771 central processing unit to beryllium install indiana LGA 775 motherboards, if the BIOS firmware support them ( merely information technology embody besides possible to add support firmware manually ). This besides allow for overclocking of Xeon ( socket 771 ) processor when practice in the compensate ( socket 775 ) motherboards. approximately overclockers rich person wield quite substantial overclocks such angstrom 4.023GHz on vitamin a Xeon X5492 for angstrom sum overclock of just over eighteen %.
