When I attempt to overclock, I encounter blue screens frequently and don't know what's causing it.
Hello everyone,
I just bought an i7 6700k and started experimenting with overclocking. Although I'm new to it, my experience hasn't been great yet. I'm using a Hyper 212 Evo, so I'm not pushing extreme overclocks, but none of them are working. For instance, I attempted a 4.4 GHz OC at 1.24v and after about 20-30 minutes of gaming, I encountered a BSOD. When I switched back to the stock settings, it didn't crash or cause any issues. I've also tried various other overclocks like 4.6 at 1.33v, 4.5 at 1.3, 4.3 at 1.22, and 4.7 at 1.4, but all of them failed to run smoothly.
Just because an MB can overclock doesn't guarantee it's built for it. However, with a high-end board, it should be suitable.
VRM is positioned close to the CPU socket. You'll notice small cubes or ceramic beads wound with wire on older boards. Each of these contains 2 or 3 transistors next to them, appearing as tiny black chips about 1/4" square. If you see finned heatsinks next to the chokes, they are already present.
Enzotech MOS-C1 forged copper is the premium choice. A more affordable alternative would be repurposing an old GPU heatsink from a 12-year-old video card. Aluminum options from China would be another viable path. The decision comes down to whether you can generate enough voltage to sustain your overclock. I've encountered some budget overclocking attempts...
It might be related to a power supply or VRM issue, not just the PSU itself. Have you experimented with adjusting the loadline settings? It could be that voltage drops under load cause the problems. I suspect it's better to stress test by pushing maximum loads rather than game loads. Previously, random crashes occurred until I increased voltages and fixed loadline calibration—now nothing triggers a BSOD.
I don't have personal experiences, but I can provide general information about typical CPU temperatures during gaming. The actual temperature can vary based on the game, system load, and cooling setup.
Your performance will largely depend on your luck in obtaining a solid chip.
As of 12/04/2016
The percentage of users who can achieve an overclock at a reasonable 1.4v Vcore is as follows:
I7-6700K
4.9 5%
4.8 21%
4.7 64%
4.6 96%
My advice is to enable auto voltages and slowly increase the multiplier for all cores.
Run stress tests ensuring temperatures stay below 85°C and Vcore stays under 1.4.
Track your results using cpu-z.
AVX instructions are rare in everyday use, but when present, they can reduce performance by a few multipliers. Prime95 is an example that heavily utilizes AVX.
If your motherboard's BIOS includes AVX offset support, take advantage of it to limit the maximum multiplier during AVX instruction handling.
The issue might relate to power supply or VRM performance. Consider adjusting loadline settings and checking voltage stability under load. Stress testing can help identify problems before they cause BSODs. Calibration involves setting the loadline properly, while VRM refers to the power management unit, not VRAM. I’m new to these technical details, so let me know if you need further clarification.
VRM serves as a Voltage Regulation Module. If it isn't built to handle overclocking, it may restrict performance gains. Adding heatsinks to the transistors can be beneficial.

VRM is a Voltage Regulation Module. If it isn't built to handle overclocking, it might restrict your performance. Adding heatsinks to the transistors can be beneficial. What are the costs of these heatsinks? Also, if my motherboard supports overclocking, should the VRM be tailored for that purpose?

Enzotech MOS-C1 forged copper is the premium choice. A more budget-friendly method is to repurpose an old GPU heatsink from a 12-year-old video card. Aluminum alternatives from China would be another option. The reason is that you might not have enough voltage to sustain your overclock. I've seen inexpensive "overclocking" MBs where the chipset only supports 95W CPUs.
