From the undervolting guide by flipfire at http://forum.notebookreview.com/showthread.php?t=235824, it seems like I am only lowering the voltage of my largest multiplier (which is 12.0x for my 1530). Do I not lower the voltage for the rest of the multipliers (11x, 10x, 9x, 8x, etc.)?
Edit: Nvm, guess I hadn't read as far down yet. Found my answer!

Yes, apparently you can... one by one you can lower for all your multipliers.. though you would have to check each of them for stability before moving on. (I thought it was mentioned there, wasn't it?? or where else did I see this?) Anyways.. Good luck

7) ***Lowering and Testing Other Multipliers voltages***
To make the most out of Undervolting, you can also lower the other multipliers to its optimum voltages. So far we have only set and tested the max multiplier.
To do the stability test on the other multipliers we will need to disable the highest multiplier by Unticking it in the Main Profile page (11x multiplier for me) then clicking Apply. This will stop the CPU from using this multiplier meaning the 10x multiplier meaning this is the highest speed your CPU will reach. Each multiplier corresponds to a clock speed 11x is 2.2ghz, 10x is 2ghz, 9x is 1.8 (for my CPU of course)
Now you know the drill...
1) Lower the voltages slowly
2) Run ORTHOS test for 45mins
3) Double check in CPU Info page or CPU-z that its stressing and maxing out at the correct multiplier
4) Find the optimum voltage
5) Move on to the next multiplier by unticking the higher multiplier profile page then back to step 1
You do not need to test the lowest multiplier (idle) because we cant change/never changed the voltage. This voltage will always set at a stable voltage
Its a time consuming process getting the optimum stable voltages for every multiplier but it pays off in the end.
Note: After your done, make sure you re-tick the multiplier boxes in the "Main Profile" page then "Performance on Demand" sub-profile page, If you dont your CPU will be majorly handicapped
The lower the multiplier #, the more sensitive the voltage is to a BSOD! Most BSOD's from undervolting are usually because of unstable lower multipliers. For first time undervolter's i suggest leaving a small voltage margin from your unstable voltages.
Quicker Alternative: If you dont have to time to stability test every multiplier there is another way. Ticking the "Auto-adjust Intermediate States" box will fill in all the multipliers in between your Idle (6x) to your highest multiplier accordingly. It seems to work well for at most cases but theres no guarantee that all the multpliers are 100% stable, since it just fills it in mathematically.

I just use Auto-Adjust Intermediate States and it works perfectly. 100% stable.

Yeah, sorry found it after I read further down XD
(Edited my original post)
Are the other multiplier effects as significant though?
