What cooler are you using? The main thing which is important is the CPU voltage. I would suggest tweaking with manual voltage first and then "dialing" it in with an offset voltage later. You do not want to run a high manual voltage 24/7. So find a manual voltage that works, and then find an offset voltage which allows your cpu to idle at lower voltages. 1.3V on Ivy will require a good cooler. I certainly prefer closed loop liquid coolers, for no other reason than they're REALLY SMALL with only the rad taking a case footprint. I prefer this to having a mammoth Noctua NHD12 covering half of my motherboard.
As far as IMC, VTT, and all that crap, i'd say it's vastly over-rated for OC'ing. In my experience (subjectively) with Haswell and IVB, processor voltage trumps everything. This is the main setting you want to mess with. Do not add variables which can compound things. Leave your memory at STOCK settings for the time being, worry about overclocking the memory later. But do understand you need a versatile cooler with both IVB and Haswell. I use the H100i on my primary desktop rig. If your cooler is terrible, your computer will certainly lock early on at 1.3V.
1.3V is also pushing things a bit. I'd aim for the 1.25 - 1.275 V range, BUT, again, GOOD COOLER required. Start with your CPU core at 1.225 to 1.25V. Understand that 1.3V is pretty excessive on Ivy - i'd definitely prefer the 1.25V range where possible, with 1.275V being the absolute upper range.
