Bare in mind that after 5 years, the life of the CPU will already have been "used up" to some extent, so don't expect an oc experience without issues. YMMV.
> I'm thinking about overclocking the daylights
a bit to get to around say 4.4ghz~4.6ghz?
For SB-E that's on the low side IMO, but then if you have a UD3 and/or the SR0H9 version then 4.4 to 4.6 is probably more realistic, especially given the age of your CPU.

This may be very dependent on the mbd. I've done a number of 3930K oc's with ASUS boards (X79 Deluxe, P9X79/E WS, R4E), for which of course offset voltage makes the most sense if one wishes to retain power saving features, but you might find this isn't compatible with the UD3. Depends on the CPU, the board, etc.
As it happens I'll be oc'ing a UD3/3930K next week, so I can send you some settings assuming all goes well.
NB: ASUS has a good guide on offset oc'ing on its ROG forum pages.
> Do i have to manually set all my turbo multipliers? I just set the cpu clock ratio multiplier on the previous page to 42 or 43 whatever.
For simplicity one can set the ratios manually. Depending on the board, for finer tuning, one could have separate multipliers such that when fewer cores are active a higher multiplier is used, ie. making better use of the available thermal headroom.
> Do i also have to set the core current limit (this and the turbo power limit are on auto)
You may well have to, but one can often do a lot without needing to. Depends on you target oc. Also, power limits & suchlike tend to become more important if one is oc'ing a system with a lot of RAM. Most of my builds had 32GB or 64GB, so such settings were critical.
> I also read about cpu offset but i havent seen that since my old ib rig, ever since i moved to sb-e, the 'dynamic' box is greyed out.
I can't comment about your UD3 (yet), but it may be that certain other settings have to be in place in order for the offset option to be available. Best check with Gigabyte, I'd be surprised if they didn't have a FAQ about it somewhere.
> Im trying to hit 4.4 but you guys reccomend 1.35 as the hard limit for 24/7?
Funny how people vary so much on this. Personally I'm happy with anything up to 1.45, but really, as Miahallen says, it's probably more sensible to go via load temps, as they will likely reach a tolerable peak level before the temps do. However, one can set goals/limits for both, eg. one could decide not to allow load temps to go above something arbitrary such as TjMax minus 10.
> I also put vtt and imc on 1.05v and pll on auto, but i read around and it said to throw it on 1.8 or 1.81.
Again, these can vary greatly between CPU samples, mbds, etc. I could mention my settings, but I don't know how they might translate to your UD3 and particular chip sample.
Be careful of jumping about changing multiple settings though, as then you won't really know what's going on. Be methodical. I recommend following Miahallen's guide, it's the best I found so far.
> I also have mixed ram, gskill ripjaws 2 sticks at cl9 1333 and 2 at cl9 1600mhz, i haven't done much but i but the settings on 'enhance stability' or something.
Mixing RAM is unwise.
Also, if you're looking for better performance, really for X79 that is slow RAM you have there (depends on the task of course, but some apps like AE benefit a lot from overall RAM clock). For an X79 build, especially with an oc'd CPU, I wouldn't use anything below 1866 (afterall, a balanced system is important). Typically I've stuck with GSkill TridentX 2400MHz kits, running at 2133 if the chip's controller can't handle all the slots being filled with an oc at the same time (I usually aim for 4.7 or 4.8), and note that sometimes 2400 kits have been cheaper than 2133. However, people speak highly of Corsair aswell, though I've had good fortune seeking used GSkill kits because they have a lifetime transferrable warranty.
The UD3 build I'm doing has 32GB (4x8) of Vengeance Pro Red 2400MHz (bought back when RAM prices were not stupid), so it'll be interesting to see how it behaves compared to the GSkill I normally use. I had wanted to buy GSkill again, but seller prices had already started to climb insanely, whereas CLL still had the Corsair kit for 116 UKP (the same kit today is 231). Review sites say the price hikes are due to a DRAM shortage, but that's nonsense, I literally saw some sites hike prices overnight after being asked why a better kit X was cheaper than a lesser kit Y. In reality it was far more about what people were willing to pay, and exploiting the Zen launch. A shortage of DRAM might explain some of the price increases, but nothing like all of it, and not the dodgy hikes I saw happening on certain sites. Oops, sorry, I appear to have ranted a bit. :}
> also what do people mean 'you can reach 4/4.2ghz on stock voltage, just dont touch it', i thought the voltage
> shoots up really high when you dont touch it, so you touch it to keep it down
Not sure on that one.
If one was going for stock voltage oc'ing, what I would do is see what it hits during normal use with everything on Auto and then dial in that voltage manually, eg. 1.25 or whatever it happens to be.
