Hello, I purchased this CPU with MOBO in June 2013 when it was first released. I have been using it daily, mainly for gaming. I’m interested in overclocking because it was overclocked from the start, but it became unstable when CPU usage went above 70% in Task Manager. Error 124 BSOD appeared frequently in modern games. I’d like to adjust it slightly to fix these problems.

I have limited experience with overclocking, but I’ve tried to grasp the differences between Manual Mode, Adaptive Mode, and Offset Mode. I’ve experimented with all three (Adaptive Mode was less stable).

I used Manual Mode and adjusted Core Voltage to 1.250 and Core Cache Voltage to 1.2, which caused a crash (124 BSOD) immediately after opening a browser. I then switched back to Offset Mode.

Currently, I’m using Offset Mode with all offset voltages set to Auto. I’ve also read that setting LLC from Auto to a higher value is recommended for Offset Mode, so I adjusted it to 5 out of 7. Initially, I noticed a significant increase in power consumption—from 20–40W to 70–85W—which is near the maximum TDP. I’m concerned about potential damage and want to confirm if this is normal.

CPU Core Voltage ranges between 1.230 and 1.280 at 4.2GHz.

MOBO: Asus Maximus VI Hero
PSU: EVGA Supernova 650 G3
CPU Cooler: CoolerMaster Masterair MA610P
RAM: 16GB HyperX Fury 1866 MHz CL10
GPU: NVIDIA GTX 1050Ti

Any advice on achieving greater stability under heavy load?

Even though I bought this CPU, a friend tested it using stability tools like IntelBurn Test and Aida64. He was surprised to find it reached 105°C with default settings—3.5GHz and BSOD within 10 minutes. It seems my unit might not be as reliable as others.

Pictures from AI Suite (DIP5) and HWMonitor, plus a picture of the case (all except MOBO, case, and CPU are 4 months old).

The TDP can be discarded when overclocking. Around 1.3 volts the CPU will consume roughly 150W. It is best to use the advanced view instead of the friendly view. You'll find many more settings there.
For stable performance at high frequency, you require higher core voltage. That's straightforward. Adaptive mode allows fluctuations; otherwise, instability may occur. Load Line Calibration can cause extra voltage under load as a correction for voltage sag, but if the load drops quickly it might overcompensate.
I chose fixed voltage settings myself; stability with offsets and adaptive was not achievable. I remember 1.29 volts at 4.3Ghz with Vin around 2.1? It's been a while since I powered on my rig. At 4.5Ghz it worked at 1.35 volts, but temperatures were too high—around 100°C almost immediately. I don't remember the exact uncore temperature, but it was probably still near 3.9Ghz.
