These chips are very voltage hungry
Yes they are. You don't buy a SB-E chip expecting good power consumption
under load. Idle isn't too bad.
DO NOT make the voltage higher than 1.40V for daily use, REMEMBER!!!
Yeah, if you're running an SB or IVB chip. SB-E handles higher voltage a bit better than other CPUs. I can run 1.45v and keep my temps around ~70*C give or take a few degrees. Right now I'm at 1.385 with high LLC which puts me at 1.385v full clocks with no load and 1.4v at full load at 4.4Ghz. I need to pump 1.5v+ through my CPU to get 80*C.
I've found that my rig in its entirety needs a lot more voltage to start overcoming 4.6Ghz and 5ghz simply isn't easily achievable and I think it's the board, not the CPU, that is limiting the overclock on my setup.
Granted I don't have the 3930k, I'm using a 3820 but the Deluxe and the Pro are almost the same board, the Deluxe just has a beefier VRM and a couple extra features.
Personally my most recently overclock is 129.5Mhz x 34 = 4403Mhz @ 1.385v, LLC @ high. These settings give me about ~63*C in a warm room while encoding video using the Zalman cooler in my specs.
I have found though at 4.2Ghz and 4.0, I can under-volt my 3820 by a lot (< 1.3v). It's not until you start going beyond that where it really wants more.
Even If my hyper X's sets the VCCSA to 1.3??
The VCCSA doesn't have a ton to do with your memory overclock. I only needed 1.15v VTT on mine to get 2133Mhz stable, 2400 likes 1.2v.
Don't go gung-ho with the VCCSA. Just keep it within 0.2v of your core voltage.
So if the core is 1.4v, put your VCCSA at 1.2v. If you're at 1.35v, then 1.15v. That rule has worked fairly well for me.
...also welcome to X79 and SB-E. Where we don't need a turbo to overclock (which is one of the reasons why I got the 3820).
