Hello,

I recently built my first ever system (I just upgraded from a Pentium 4

). I'm new to the overclocking scene, but this is what I have:

CPU: Intel i7 4930k @ 4.5GHz 1.35v (Stress testing on Prime95, with Realtemp says that lowest temperature is 28°C, and the highest is 77°C)
CPU Cooler: Swiftech H220 Water Cooler
Ram: CORSAIR Vengeance Pro 16GB (2 x 8GB), 1866Mhz
Motherboard: Asus Rampage IV Extreme
GPU: nVdia 780TI Classified (SLI)
Case: Corsair 540 (I put three fans in the front, with the H220 Radiator on top).
Power Supply: AX860i ATX Power Supply - 860 Watt (80 PLUS Platinum)

I overclocked the CPU recently to 4.5GHz, and it's stable at 1.35v. I ran prime95 a couple of times overnight and I launched CPU-Z, and saw that the core voltage is not at 1.35v. It increases to 1.376v, and usually goes to 1.384v.



Is this something I should be concerned about? Should I increase my core voltage to 1.376v or 1.384? Please let me know, thank you!

I haven't received any BSOD with my configuration so far. I ran prime95 for a week every night, and memtest every night for a week. No errors.

This is because of Load Line Calibration. It causes the VCore to increase rather than drop under heavier loads. The Auto setting on the Asus board usually sets it to High. This is fine, try to reduce the Vcore to the minimum now.
