6700k unstable overclock
6700k unstable overclock
Geraltofskylake has appreciated your response. I am currently evaluating RAM configurations provided by G Skills.
The recommendations they shared:
DRAM Frequency: 2800MHz
DRAM Voltage: 1.25V
CL-Timing: 15-15-15-35 (tCL-tRCD-tRP-tRAS)
Command Rate: 2T
It appears to be functioning properly, and the system has remained stable after manually applying these settings in the BIOS. My CPU continues to draw excessive power, often exceeding 1.4V. It seems the problems stemmed from incorrect RAM timings and a defective CPU.
Skidushe has responded with gratitude.
I am facing system instability and attempting troubleshooting. I have reset all settings to their defaults to identify the root causes.
I experience elevated CPU voltage, consistently above 1.4V at default, and my processor runs quite hot, especially when using NH-D15 under Prime95.
Several issues point to instability: the PC shuts down via Windows but leaves a blank screen until manually terminated. The taskbar doesn’t disappear during fullscreen video playback, and changing browsers hasn’t resolved the problem. I’ve tried rebooting, but the Start Menu becomes erratic, with flickering images and no functionality.
I am confident the issue lies with the motherboard or CPU. I will continue testing and plan to replace the faulty component. For now, I will avoid overclocking.
Skidushe advises:
Upgrade the BIOS if a newer version exists, or reset default settings if not.
Open Advanced mode in the bottom right corner and click on the AI tweaker tab at the top.
Refer to the provided links for guidance:

Enable XMP as indicated, and disable ASUS multicore enhancement.
Adjust CPU core ratio to synchronize all cores (change '1 core ratio limit' to your multiplier).
Assuming your BLCK is 100 (as it should be with BIOS defaults):
42 = 4.2GHz
43 = 4.3GHz
44 = 4.4GHz
45 = 4.5GHz
Recommend setting to 44 for now.
Change CPU core voltage manually from auto to a fixed value—ideally 1.35V.
This is for testing purposes only; it remains high for a 4.4GHz frequency and should be stable with all 6700k processors I’ve tested.
Run stress tests using Prime95:

Perform a blend test and let it run for some time. If uncertain, consult the Intel Temperature guide (section 11-14).
If the test completes without errors and temperatures stay below 80°C, proceed. Lowering voltage in increments of 0.01 until instability occurs, then returning to the last stable value is advisable.
Clearing CMOS on your motherboard may resolve shutdown issues. The excessive voltages likely result from the board automatically supplying too much power. Adjusting the voltage should help unless you’ve lost the chip entirely.
Additionally, consider a fresh Windows installation for other hardware-related concerns.
Have you tried the original setup instructions? They might address the CPU overheating issue. Be sure to reduce the voltage to its lowest stable level.
