LGA1366 Socket NCTF Solder Joints
Intel has defined selected solder joints of the socket as non-critical to function (NCTF) 
for post environmental testing. The processor signals at NCTF locations are typically 
redundant ground or non-critical reserved, so the loss of the solder joint continuity at 
end of life conditions will not affect the overall product functionality. 
 
identifies the NCTF solder joints. 
.
Note:
For platforms supporting the DP processor land C3 is CTF.
