CPU Overclock Advice
CPU Overclock Advice
Hi there,
I just started my first overclock and have a few queries to share.
With Intel Extreme Tuning Utility, I’m running an i5 4690K at 4.3 GHz and 1.170V. During stress tests the temperature peaked at 74°C, but after a long gaming session it rose to 78°C. Now I manually keep my fans at full speed during games and stay below 71°C, which works well for me.
My first concern is about the cache ratio. Most recommend matching it to your core ratio or keeping it slightly lower. I set mine to 4.2 GHz, so a 100MHz reduction—does that make sense? How crucial is this setting?
My second question concerns the cache voltage. I originally adjusted it 0.025V below my core voltage, but after an online reset it changed to 1.080V (possibly the default). Since then I’ve maintained that setting and haven’t had any more crashes. Should I keep it like this? Is it really necessary?
Looking forward to your advice.
Cheers.

Hello there,
I just started my first overclock and have a few queries I’d like to discuss.
With Intel Extreme Tuning Utility, I’m running my i5 4690K at 4.3 GHz and 1.170V. The peak temperature during stress tests was 74°C, but after a long gaming session it climbed to 78°C. Now I manually keep the fans at full speed while gaming, and I no longer exceed 71°C, which is satisfactory.
My first concern is about the cache ratio. Most recommend matching it to your core ratio or keeping it slightly lower. I chose 4.2 GHz, so a 100MHz buffer—does that make sense? How crucial is this setting?
My second point concerns the cache voltage. I originally set it a bit below my core voltage...

Hello there,
I just configured my first overclock and have a few queries I’d like to discuss.
With Intel Extreme Tuning Utility, I’m running my i5 4690K at 4.3 GHz using 1.170V. The peak temperature during stress tests was 74°C, but after an extended gaming session it climbed to 78°C. Since then, I’ve kept my fans at full speed while gaming and now stay below 71°C, which I’m satisfied with.
My first concern is about the cache ratio. Most recommend matching it to your core ratio or keeping it slightly lower. I set mine to 4.2 GHz, so a 100MHz buffer under is reasonable? How crucial is this?
My second point concerns the cache voltage. I originally set it 0.025V below my core voltage, but after an online reset it changed to 1.080V (possibly the default). Since then I’ve maintained that setting and haven’t had any more crashes. Should I stick with it? What’s the impact?
I understand this advice is for a Gigabyte motherboard, but it should help clarify your questions.
I found this guide useful when working with a Haswell CPU:
http://www.overclock.net/t/1401976/the-g...g-oc-guide
In that guide, the core cache ratio is listed as uncore, and later sections offer helpful references if you’re unsure.
