Skylake 6700k fixed voltage
Skylake 6700k fixed voltage
I have a Skylake 6700K that I've overclocked to 4.5ghz at 1.264 volts. The voltage stays steady at 1.264v even when idle and the clock runs at around 1500mhz. I'm new to overclocking, so I'm unsure if keeping this voltage constant when not under load is safe. My PC is on for about 12-15 hours daily and only used for a few hours. Is there a way to lower the voltage automatically when the system isn't busy? I checked the BIOS but don’t know what settings to adjust. My motherboard has an ASRock Z160 K6 with fixed voltage, which might affect this. If I don’t get 1.264v, the overclock won’t work properly.

I'm new to overclocking, so I'm wondering if keeping that voltage constant when the system isn't under load is safe. My PC is on for about 12-15 hours a day and only uses it for roughly six hours. Do you know how to adjust the voltage when it's not under stress? I've checked the BIOS but don’t have a clear answer. My motherboard has an ASRock Z160 K6 with voltage set as fixed, so it might be related to that setting. If I don't get back to 1.264v, the overclock won't work properly.
when voltage is manually adjusted instead of auto, it remains constant as in your situation. this approach offers certain benefits. by fine-tuning properly, you can achieve the lowest stable value at a fixed clock speed. with auto voltage, you tend to encounter higher readings during heavy system demands, often reaching unsafe levels over time. i’m unsure about the optimal safe voltage for skylake for long-term use. hawell is roughly 1.3 volts, and cautious users usually prefer keeping it below that. my 4790k is set at 1.21 volts. don’t worry about fluctuating clock speeds—when you need the cpu, it will be available, and if the load is light, speed will adjust accordingly.
I use various tools to keep track of my system, including CPU-Z. It shows my core voltage is currently .368 volts, and the program Core Temp 1.0 lists my VID as 1.2114. *shrug* Both are correct. My actual energy consumption changes a lot depending on what’s running. I don’t think there’s anything urgent to worry about. Still, if you aim for your system to last a decade, you might want to reduce the voltage below 1.2 and adjust the CPU clock as well.
When you overclocked, did you change the voltage or just tweak the CPU clock? If you only adjusted the clock, lowering the voltage should help. Start by reducing the voltage by .01 volts with each adjustment, then run a stress test. If the system crashes during testing, you’ll need to add back .01 volts and save your BIOS settings.
I switched the voltage to auto, allowing it to adjust based on load instead of using a fixed value. However, I noticed it briefly reached up to 1.344, which is too high for my preference. During a stress test it remained around 1.234 and then froze after about 30 seconds.
You could have modified the voltage or just changed the CPU clock speed. If you only tweaked the CPU, lowering the voltage might help. Begin reducing it by 0.01 volts with each adjustment and then perform a stress test. If the system crashes during testing, you should restore the voltage back up to 0.01 volts and save the BIOS settings.
When I overclocked, I adjusted the fixed voltage to 1.265, which is actually 1.264, since it wasn't stable at 1.260. 1.264 is the minimum voltage I can use for a stable OC of 4.5ghz.
Here you are, that's your response. It's good to proceed at 1.265 and keep going. Unless you're comfortable with a lower overclock, I believe you'll be fine with the voltage for at least three years. Maintain a cool environment and enjoy the upgraded system. I'm interested in Skylake (DDR4, m.2 PCIe, voltage regulator updates, and PCH), but I already have a significant investment in my Haswell setup. It seems like I'll wait a few more years before making major modifications.
