I'm about to pull the trigger for a Z87 Sabertooth in amazon but not sure yet.
They all still have the issue, but it is pretty much a non-issue. If you use a hub (and some motherboards have built-in hubs) then it isn't affected, it doesn't seem to happen for all USB drives (mine all work fine, for example) and there is supposed to be a Windows hot-fix coming out to fix it in any case. So in short, don't bother waiting for the new motherboards.

I'm getting roughly the same results. Still need very high voltage for relatively low clocks. i.e. 1.35v for x44. Maybe my sabertooth is bad? PSU?
What's your uncore? Try locking it down at 35 or 36 and see if that helps.

Issue being, it is taking HUGE amounts of Vcore, and still not stable.
I can enter windows up to 4.7, and can post up to 5.0 (though I didn't even try for 5.1)
I initially wanted a 4.8 overclock, but am planning on settling on 4.6 if I can even get that stable.
My temperatures average around 80, with a high of 92 and Aida detects no throttling, though I cannot stay stable for more than 10 minutes of Aida.
Strap - Auto
BCLK - 100
Multi - 46
Uncore - 43
VCore - 1.325 (I want this lower)
VRin/Input - 1.95 (Have tried 2.0 with no change)
Vring/ Uncore Voltage - 1.3
System Agent - (+).015
Somehow I need to make this stable, and hopefully lower my temps. I have been considering De-Lidding, but haven't because I am scared(*).
(*)Note: I am not scared of the delidding process, I am scared of having to buy $30 TIM to apply.
Any tips/ changes you think might help?
1.325 is certainly not HUGE volts for 46 - lots of people need 1.35V for 44. Try lowering your uncore, or testing the speed you have now with just the cache test of Aida, if you haven't already. Quite possible the 43 uncore is killing your stability. Try dropping it to 35 or 36, there's no appreciable performance difference anyway.
