I7-4790k Stock Boost 4.4Hgz with Vcore set to 1.283! Is there space for an overclock?
I7-4790k Stock Boost 4.4Hgz with Vcore set to 1.283! Is there space for an overclock?
Hi everyone.
This is my first attempt at overclocking my CPU. I have no prior experience with this.
After some research, it looks like I'm facing a bit of a challenge. Most recommend keeping the Vcore voltage below 1.3v, so I seem to have limited room for adjustments. Right now it's already reaching 1.283v when the system auto-boosts to 4.4Ghz. It's currently running at its default speeds, and I've never even touched it before.
Even a small increase of 0.05 (50mV) suggested for every 100Mhz would push the Vcore above the recommended level for continuous use. I'm not sure I can go that high—maybe up to 4.5?
Is it really worth trying to make these changes?
Thanks.
Jo.

Hi everyone.
This is my initial attempt at overclocking my CPU. I have no prior experience with this process.
After some research, it seems I'm facing a bit of a challenge. Most recommend keeping the Vcore voltage below 1.3v, which means I have limited room for adjustments. Currently, it's already reaching 1.283v when the auto-boost reaches 4.4Ghz. It's running at its normal speed now, and I've never even touched it before.
Even a small increase of 0.05 (50mV) suggested per 100Mhz would push the Vcore to 1.333v, which exceeds the recommended level for continuous use. I'm not sure I can go that high!
Is it really worth trying to make these changes?
Thanks.

Just because the voltage reaches 1.283 with stock settings doesn't mean it requires such a high value for that frequency. The standard voltage/frequency setup isn't always fully optimized. You might be able to lower the voltage while maintaining the same frequency, or slightly increase the speed without changing the voltage.
1.3v is a bit too low. 1.35v is actually the highest safe level.

That was my perspective too... I'll test it and adjust accordingly.
TechInAZ:
The 1.3v setting is quite cautious. The 1.35v is actually the upper limit you should consider.
Thank you for your feedback.
Can I maintain 1.35v continuously? Will it affect the lifespan of my CPU? Even a small risk would make me hesitant to go that high.
Jdj9 provided some advice on overclocking. They mentioned that 1.3v might be too low and 1.35v is the recommended maximum. They asked if it's safe to keep 1.35v running continuously and whether it could affect the CPU's lifespan. They noted that increasing voltage always shortens CPU life, but staying below 1.32v is safer, especially underwater. They suggested 1.35v is acceptable if submerged and recommended avoiding anything under 1.32v otherwise.

Most users who boost their CPU speeds to hit a certain clock rate while keeping Turbo Boost off in the BIOS will avoid voltage spikes and maintain a steady 4.4Ghz performance.
I suggest turning off Turbo Boost first before attempting any overclocking, then proceed carefully.
Thank you for your advice.
I've also seen what you mentioned elsewhere, though I'm not sure where exactly. Maybe in the forums.
If I decide to overclock, I'll follow your suggestion and disable Turbo Boost.
TechyInAZ shared their thoughts on the topic. They mentioned that 1.3v is somewhat conservative and 1.35v is the recommended maximum. They asked about keeping 1.35v at all times and whether it affects CPU lifespan, noting that even a small risk should be avoided. They emphasized that increasing voltage shortens CPU life and suggested staying below 1.32v for safety, with 1.35v being the standard for underwater use.
