Check if the temperatures and voltages are within acceptable ranges.
Check if the temperatures and voltages are within acceptable ranges.
I recently increased the overclock of my I7 6700K from 4.0 to 4.4 and wanted to check if the temperatures and voltages are within safe limits, especially since these readings were taken during a stress test.
Intel temperature guide: It seems the 4.4 OC is just 200Mhz above the stock 'boost', so you probably don't need to significantly raise the voltage for that (usually). You should have enough headroom there. Regarding temperatures, it appears you only ran Prime95 for a short time and temps are still rising. An air cooler should bring things down in a few minutes, while an AIO liquid cooler might stabilize within about 30 minutes. I wouldn't label your OC as a "70'C" at this early stage... give it a bit more time. *Keep in mind Prime95 is putting a lot of stress on your CPU beyond what you'll actually use in daily tasks, making it a real "worst case" scenario.*
Under 70 on stress and fairly balanced across all cores? Thumbs up
Quick tip 1.35v for 4.6ghz
Under 70 under stress and fairly balanced across all cores? Thumbs up. Rough guide 1.35v for 4.6ghz. Thanks a lot, I don't want to go further since I've heard that above 1.350 volts isn't ideal.
Intel temp guide: It seems the 4.4 OC is just 200Mhz above the stock 'boost', so you probably don't need to raise the voltage much for that (usually). You should have plenty of room in voltage. Regarding temperatures, it appears you only ran Prime95 for a short time and temps are still rising. An air cooler should bring things down within minutes, while an AIO liquid cooler might stabilize after about 30 minutes. Don't label your OC as a "70'C" at this early stage—give it a bit more time. *Keep in mind Prime95 is putting a lot of stress on your CPU beyond normal usage, making it a real "worst case" situation.*
Barty1884 provided a temperature guide link and noted that the 4.4 OC is only slightly above the stock 'boost' speed, suggesting you don’t need to significantly increase voltage. Temperatures likely still rising after short Prime95 runs. An air cooler should stabilize them in a few minutes, while an AIO liquid cooler might take closer to 30 minutes. The OC isn’t yet at a "70°C" level, so continue testing for a while and adjust accordingly.
Every board or chip will have slight variations. I think the 'stock' voltage for a 6700K @ 4.0-4.2Ghz should be around 1.2V. I anticipate 4.4GHz could work at about 1.3V or a bit lower, though that's just an estimate. Since each chip/board is unique, I probably can't push much higher. My current stock voltage is 1.295, which I raised to 1.345 for overclocking.
Your boards have a voltage of 1.295? With proper cooling (including the VRMs on the motherboard), you should be able to reach 1.4V as per the Intel temperature guide. Could you tell me what motherboard you're using and which cooler you have?
