Voltage differences observed in the 17-6700k unit
Voltage differences observed in the 17-6700k unit
Key details include a motherboard model, an i7-6700k processor, a Corsair H90 cooler, DDR4-3200 memory, and additional fans for cooling. I'm aiming for a stable overclock on this system. After reviewing instructions, I tried running the CPU at 4600mhz with 1.35V. I also used the XMP profile for my memory to reach the 3200MHz target.
During a four-hour stress test using RealBench while tracking with CPU-Z and HWmonitor, everything performed well—maximum CPU temperature reached 77 degrees, and other metrics stayed normal.
However, I observed that the average voltage reported during the test was 1.376v, which is higher than expected. It even spiked temporarily. Even when idle, the voltage reads 1.36v. This makes sense if I set the BIOS manual voltage to 1.35v.
I need to understand this before adjusting voltages further in order to identify my lowest stable setting. Thanks ahead of time.
LLC is Load-Line Calibration designed to lower vdroop, ensuring a more consistent vcore output to the CPU whether idle or under load. Setting the vcore to 1.35 should result in a stable voltage around 1.35V. You can test stability by running your system at 1.25V for 4.6Ghz; if it's not stable, gradually increase the voltage until you find a reliable value. It’s better to determine a stable vcore at a specific frequency rather than working backward from a target voltage.
Did you change the LLC settings or keep it on auto? You might want to switch to level 3/4/5 instead.
You could possibly run at 4.6Ghz around 1.25v instead of 1.35v.
Whoa, really. I don’t understand what LLC is—it’s still set to auto.
If I change it to one of those levels, can I adjust the vcore?
