Core i5 3570k OC'd to 4.4GHz @ 1.185 volts manual (seems to stick at 1.192V actual... is this due to spread spectrum?)
ASUS P8Z770V Pro with latest BIOS (rev. 1708)
4 x 4 GB Samsung DDR3 RAM
two Geforce 670 GTX in 2-way SLI
Seasonic Platinum 880watt
Samsung 830 Pro 256GB SSD (OS/apps)
1 TB WD Black (storage)
Windows 8 64-bit
What I want to do:
I have my computer running stable at the current voltage (though I may push to lower it a little more over the holiday) using the manual settings, but I'd really like to figure out offset overclocking. The guides I've read haven't been very helpful, since none of them seem to explain why the voltage fluctuates so damn much from one boot to the next when in offset mode, nor where/how to set the max voltage threshold in my UEFI. Yes, I've read some of the offset overclocking guides in this forum.
I would like to keep all the power saving features enabled, but just up the max voltage threshold in order to support my OC. I've done extensive reading that indicates keeping the C-states enabled is actually a good idea on OCing the newer chips, though I'm still a little fuzzy on spread spectrum's practical application.
I could really use some input here on how to force a max voltage threshold (so it won't do that crazy-ass 1.3xx voltage level that the ASUS board likes to do).
