Zippy It seems unlikely at 191 but you might be running into a bit of a baseclock hole. At the point where you are at I'd try a few things.
First I'd walk up the baseclock one MHz at a time from 181. Doing that does it feel like you are hitting a wall or are you having to increase the vcore gradually as you go up? I hit a baseclock hole at 204. 203 was easy enough but 204 just wasn't happening. Finally it took a pretty good punch of VTT to get over it.
2nd if there is a hole there you are already getting over it by jumping to 1.39v. Maybe in your case the VTT isn't the issue and you are just needing the vcore to dig out of it. So now that your on the other side what can you do with that 1.39v. Try walking the baseclock up. Haven't heard you holler about temps at 1.39v so it might be worth seeing how far that will get you. Systems tend to have sweet spots. For my i5 it's 4.01, for my i7 3.8 maybe for you it's 4.4
3rd. Try ditching 21. Maybe your chip likes 22 or 20 or 19 better. You won't know until you try.
At 1.39 that thing loads a 80c. The problem is 1. those temps are higher then my liking for a 4.0 overclock (I am going to mess with my h70 and see if I can get them to come down) 2. I have a foxconn socket and don't want to push it that high in fear of blowing it out.
The thing that suck is I don't even know if 1.39 is that stable. I know it can pass a quick intel burn test but....I mean the fact that I need so much vcore sucks.
If it is a bclock hole is the mobo or cpu responsible for that? Also I don't have the x22 option. I think I have to turn turbo on for that.
