Hey Reg, just wanted to drop in and add my thoughts. Many of us are old school when it comes to overclocking, so I tend to stay away from "auto" overclocking utilities and do all of my adjustments directly through the BIOS. Overclocking a 2700K to 4.2 or 4.3Ghz is usually a walk in the park.
Check to make sure your motherboard came with the latest BIOS revision - if not flash to the latest.
Once you get your build done make sure to run Memtest for an hour or so at stock BIOS settings. If that passes, go ahead and install the OS, drivers and Windows updates and get your OS straightened out before you begin overclocking.
At this point you are ready to start overclocking.
1) make sure you are running the latest BIOS - if so load optimized defaults and reboot.
2) click the OC (overclocking setting) tab in the click BIOS - make sure you select "standard" mode from the top (there are three options, namely; eco mode, standard mode, OC Genie II mode)
3) scroll down and make sure that CPU Base Frequency is set at 10000
4) adjust cpu ratio - change from Auto to 42
5) dram frequency clock - change from Auto to 1333
6) dram timing mode - change from Auto to Manual
7) advanced dram configuration - set the four primary memory timings according to the specs of your memory modules
8) cpu core voltage - change from Auto to 1.28v to start with
9) vdroop control - set to 80% to begin with (may be able to reduce once you get stable) - the key here will be finding the vdroop control value that maintains load cpu voltage near what you have set as the cpu core voltage (i.e. 1.28v)
10) dram voltage - change from Auto to the voltage according to the specs of your memory modules
You shouldn't have to change anything else. Save changes and reboot. Perform a short run of Memtest, 30 minutes or so just to make sure. If it passes load into OS and run Prime95 or OCCT for a couple of hours. If all this passes you can perform extended test runs of Memtest and afterwards Prime95. Personally I run Memtest overnight. If that passes I run Prime95 overnight.
