on ref 5870 that VRM slave with a missing brother in the top left is the VDDCI, its vt1165 controller is in the extreme top left corner.
memory VDD is the 2 above the missing 5th VDDC phase on the right (looks like those 2 are actually set up to run as a 2-phase... hard to tell from tiny pics)
on nonrefs... well, anything can be anywhere
edit: nope, those 2 are 2 single vt243s, most likely memory VDDC and VDDQ

Yes I am interested in this VRM. What does it do exactly ?
Seriously, VDDCI = "uncore" ... as far as I can tell it's PCIe and memory controller core voltage.
