Socket T or LGA 775 (Intel)

LGA775 is a relatively recent socket, which was surprising when it was released to the market as it was without any pins. Instead, the pins were on the motherboard and pushed against lands on the CPU substrate. As a result, many motherboards were RMA’d by novices who had damaged the pins inadvertently, and this posed many headaches for computer shops in general.

Typical Thermal Solution

The Intel supplied coolers have an “orb” style and feature a four-wire PWM connection for speed control. The height of the heatsink varies depending on the TDP of the model it was bundled with.

    I’ve built and services many machines with this socket! The retention mechanism for the heatsink was a bit fiddly but on the whole fairly easy to use. You just had to be careful not to bend the plastic on the ends of the pins.

    We had to re-apply thermal paste to these processors on a much more regular basis than others for some reason. Perhaps it was just the volume sold, or the way people kept their systems.

    The pins on the mainboard didn’t get bent that often between the supplier and OEM because the sockets had a little shield to remove before putting the cpu in. I only ever saw a few bent pins, as you say because of installer mistakes, but one or two came from the manufacturer that way. If handled with care, and keeping the shield in place until ready there was little chance of bending the pins.

    I still have skt. 775 Core2quad Q9300 in 2015, it serves me well after all that years, oc. at 3,5Ghz it’s always energy hungry.
