High temperatures when using an i7 920 overclocked are common.
High temperatures when using an i7 920 overclocked are common.
Hi everyone. I own an old i7 920 that I've overclocked to a stable 3.8GHz, paired with a Corsair H115i watercooler. I've been using it for months without any problems. Recently, though, my core temperatures are climbing to 82-84°C while playing Battlefield 1, which keeps the CPU at full load for hours.
During this overclocking process, I only checked the CPU temperature reported by the motherboard. None of the guides I read suggested checking the core temps. Now I realize that core temperature is what really matters. I'm currently running a 45% overclock, and even at just over 1.3 volts, the core temps are reaching 84°C. The cooler does a great job keeping the CPU at 70°C or lower, but these cores seem to be overheating significantly. I know this processor tends to get hot, but others claim they can easily reach 4GHz without such high heat. What's happening? Any advice would be appreciated.
Specs:
Motherboard: ASUS P6T
CPU: i7 920 @ 3.8ghz, with Corsair H115i watercooler
RAM: 12GB DDR3
GPU: Nvidia GTX 1060 6GB
Hi,
I was reading the temperature from Realtemp/coretemp before. Voltage does raise heat, and 1.3v is often recommended but might be a bit lower depending on memory speeds and CPU characteristics. Memory stability is a key concern here, so adjusting the frequency could yield better results at lower voltages. Hyperthreading can also contribute significantly to heat generation. In my experience, I've had a 920 running at 4Gz still today if you try those settings.
Hi,
I was reading the temperature using Realtemp/coretemp. Before that, I looked at the bios. Voltage does raise heat, and 1.3v is typical but might be a bit lower depending on memory speeds and CPU characteristics. Memory stability is a key concern, so adjusting the frequency with lower voltage could yield better results. Hyperthreading also contributes extra heat. In my experience, I've had a 920 at 4Gz still working if you try those settings.
Hi,
I was thinking about using Realtemp/coretemp. How were you interpreting the temperature readings in the bios? Voltage does raise heat, and 1.3v is typical but might be a bit lower. It really depends on memory speeds and CPU characteristics. Memory stability is often a key factor, so adjusting the frequency could yield better results at lower voltages. Hyperthreading can also contribute significantly to heat generation.
In my experience, I've run an Intel 920 at 4GHz still today if you try the settings I used. Boju, thanks for your advice. I spent several weeks fine-tuning my configuration and found that 1.325 volts gave me the most stable performance at 21*181. I lost the silicon lottery with this D0 chip, so I'm trying to lower the voltage a bit more. My main worry is whether I should go through all these adjustments since 1.325v seems reasonable.
Core temperature is currently around 46°C, which feels quite high for me. I just replaced the water cooler with fresh Arctic Silver and temperatures are now at 79°C during Prime95 tests instead of the previous 90+. I'm hoping this keeps improving. Thanks for your support!
