1.3v a little too high?
1.3v a little too high?
Hi everyone,
Three years ago I assembled my PC using a 4770k 3.5ghz Haswell processor and aimed to push its performance further. I attempted to use the Asus Suite III for auto overclocking, which increased the speed to 4.2ghz. However, the voltage stayed well below 1.1V and occasional crashes still occurred. I decided to manually adjust the settings from the BIOS. After that, I raised it to 1.2V at 4.2ghz and even 1.25V at the same frequency, but crashes persisted until I reached 1.3V. Is 1.3V really too low for longevity, given that temperatures stayed under 70°C during gaming? Also, Prime95 tends to generate significant heat after a while, so I prefer avoiding stress tests with it.
My setup:
- 4770k 3.5ghz
- 212 Evo air cooler
- Asus Z87 Plus C2
- Cooler stryker master case (large case)
- 16GB DDR3 RAM
- GTX 1070 Founders Edition
- 750w OCZ power supply
- BenQ Zowie XL2411 144Hz monitor
1.3v represents the maximum limit for Haswell. You could examine the settings from the ASUS auto overclock and increase the voltage slightly beyond the 1.1v it provided. Your CPU is likely to become outdated before it stops working. One option is to use speedstep and adaptive voltage, which will lower the multiplier and voltage when the CPU is idle. Your temperatures during load remain acceptable. It requires around 100°C for the CPU to slow down or shut down to safeguard itself.

You could check the settings from the ASUS auto overclock and increase the voltage slightly beyond the 1.1v it provided.
Your CPU might become outdated before it stops working.
A possible solution is to use speedstep and adaptive voltage, which will lower the multiplier and voltage when the CPU is idle.
Your temperatures during load are normal.
It usually takes around 100°C for the CPU to slow down or shut down to protect itself.
Appreciate the advice!
