Well we need to know what revision you have? A single PCB or dual PCB 295.
2nd. The IC... I found this ADP3193A
chip that should be on your card too! We are looking for FB.
Also found this thread
that explains the mod well, but using VID.
I prefer VR modding where you use a variable resistor in parallel with FB (Feed Back pin) You can find that in the datasheet above. You just need to measure the FB with a DMM, multiply by 20 and you get the right VRs resistance for the mod (eg.: My FB is 600OHM. 600*20=12000. I need a 12000OHM VR or more for the mod!) measure/connect between FB pin and GND.
OCP is explained well in that thread so that's done. Solder the VR between OCP pin and GND.
RT is interesting too. That controls the frequency of phase switching. You can have fun with that if you want. Same as FB. Measure, multiply by 20 and you get the VRs value. Oooor you can just pencil the corresponding resistor to a lower resistance. Lower the resistance to 20-40% its original value (eg.: the resistors value is 40kOHM. Somewhere 24-32kOHM is optimal. But if you're not interested, you can just leave it.
Have fun with it!
