You can go to the EVGA site and download it.
CPIUD does not tell you the voltage your memory is running, it tells you what the register settings on the memory say it should be running at for a given speed setting.
Yes, if your memory says 1.7, then it should not need 1.87. But, you should be able to tell exactly what you are setting it to in the BIOS if you are doing it correctly. Do not use the "+ 5%, or 10%" type of settings your are going to find, there should be a field where you can set the voltage exactly to what you want, no percentages.
As I said, read your manual.
