AMBER gives the following results:

 NSTEP       ENERGY          RMS            GMAX         NAME    NUMBER

BOND    =      216.2588  ANGLE   =      724.0684  DIHED      =     2516.9902
VDWAALS =    -1292.7545  EEL     =   -19141.1870  EGB        =    -3682.0180
1-4 VDW =     1317.8423  1-4 EEL =    12210.1621  RESTRAINT  =        0.0000
ESURF   =    14081.5300

Note the following: VDWAALS + 1-4 VDW = -1292.7545 + 1317.8423   = 25.0878

                    EEL + 1-4 EEL     = -19141.1870 + 12210.1621 = -6931.0249

NAMD gives the following results:
