Op, I'm glad to hear you somewhat got your issue sorted out. I've had my hands on a few boards and i7 6700k's, Asus seems to squeeze out those extra MHz the best if your considering another board.
The folks running the higher clocks on Skylake aren't afraid of voltage that's for sure. Personally I'm not comfortable going more than 1.35v. With the rate of IPC improvements I may be hanging on to this chip a while, thus why I don't want to push too hard. I have to admit there is a curiousity of what my chip would do at 1.4v and over. My prediction is 4.7.
With all that said I have to ask at 1.43v, what kind of temps are you seeing in the latest version of prime 95 small FFT. Say at just a 30min to hour run?
Well, I managed to grab the computer back from my friend I sent him the other day and redid a whole suite of oc tests back and forth. One chip performs slightly better than the other. The one I was using the other day was a dud. Basically here are the results of the experiments.
Chip 1: 4.4Ghz @ 1.36v => 4.5Ghz @ 1.41v => 4.6Ghz @ 1.46v
Chip 2: 4.4Ghz @ 1.33v => 4.6Ghz @ 1.40v => 4.7Ghz @ 1.49v
Temps on my corsair were around 77C or lower except when I was going above 1.45v. Then they were spiking up to 85C when running prime95 v28 with AVX. On my friends air cooling setup the temps were a bit higher. Usually around 80C spikes with the temps going to 90C when the volts were higher than 1.45v. If I just ran small FFT's on prime 95 with 1344 size temps were down a tiny bit further by about 4C across the board.
In neither case can I get the memory I have to run at proper rated speeds. I manually put in every config for timings and volts I could do. I loosened things way up too. Nothing worked. The moment I tried to use 3200 as the bandwidth or higher with both chips on the board the bios would refuse to let the system get beyond the memory check and force me back into the bios to change it.
So at this point, because the memory isn't being allowed to go where it needs to go, going to try to contact the seller of the board+cpu and see about get a swap out. Letting the friend keep the better chip and sending back the crappier one. So Chip 2 is in friend's PC humming along at 4.6 at 1.4v right now on his air cooling setup and doing fine so far. I'm chugging the 4.4 one currently.
