have not found one picture of DL380 G9 mboard with all chokes populated. but have seen some with 2 missing (3 left) before.Oh! I will check both of my motherboard models to check this. My hpe motherboard should not have any missing since it supports this model.
even with 4 chokes the E5-2696v4 is started, if the icc_max is 199A. E5-2696v4 does not draw more current than a 2699v4.
E5-2687W v4 TDP=160W TDC=189A
E5-2696v4 TDP=150W TDC=199A <- just to make it unsupported
