Opteron 165 different voltages for each core?

Hey I just installed speedfan and my voltage values for VCOREA and VCOREB are both different! I recently did the voltage mod to my ASRock board. Right now it's supposed to be 1.5V but VCOREB is 1.66V! Right now I have my Opteron 165 oc'ed to 2565 (285x9). Also in my previous overclocking attempts, accidently I left the HTT multiplier at 4x. If your HTT is over 1000 (in this case 1140), would it be a source of instability, like causing PRIME to fail?

yes it will cause prime to fail and your North Bridge gets EXTREMELY hot... i didt he same thing but i had my HTT at 12xx MHZ :) itll run but it REALLY doesnt like it at all...

from what i know about teh cores is that they are the same voltages and the VcoreA and B are differnt on mine...
like on my mobo i have my core at 1.45... i have same as you
VcoreA: 1.44-1.46v
VcoreB: 2.21-2.24

i think its just some other voltage its reading.... not rally sure what... buat at 1.45 im at 2.22Ghz

My impression was that Vcore2 represented VDIMM, at least that's what it equals on my VNF3-250 and VNF4-Ultra.
