Secure continuous overclocking and stable temperatures for the I7 4790K.
Secure continuous overclocking and stable temperatures for the I7 4790K.
I’m trying to understand this a bit, since I’m new to it. I might be able to get a clock speed around 4.9 with a Vcore near or just above 1.3. But with my temps hitting 85 at 1.25v and 4.8ghz, I believe pushing to 1.3v would definitely push me into the 90+ range with my current cooler, which I’m not ready to risk. If I still decide to go overclock, I’d use voltage offset so I don’t have to run at that voltage constantly.
Still, I’m just reinforcing my own caution. Every overclocker has to realize they’ve pushed their cooling limits and learn to stop before harming the hardware. Either halt now or improve the cooling to allow safer, higher temps.

This is basically what HWMonitor is showing as my VTT, maybe HWMonitor is mistakenly displaying this voltage since my VTT isn't available? How likely do you think it is that HWMonitor is reporting my VRIN as my VTT?
As I mentioned before, I wouldn't rely on HWMonitor being accurate. Just like your Gigabyte motherboard, my ASRock doesn't have a BIOS setting for VTT, so it's not a big concern.
What clock speed is your memory?
2133 Mhz, I turned on XMP 1 in my BIOS and it seems (based on my limited understanding) that everything was set up properly to let it run at that speed. When I first turned on the system, it was probably only around 1600 or so.
And to 4Ryan6 I'm quite satisfied with 4.7Ghz, especially since it runs at a lower voltage than what my processor was using for 4.4 turbo boost.
I admit, I expected cooler temperatures from my Phanteks cooler, which was supposed to be the top air cooler available, but I probably underestimated how much heat this processor generates.
From what I understand, some users need aftermarket coolers just to keep the chip running at stock speeds.
To be honest, I might switch to water cooling eventually, but not until I really need it.
(Read: about 2-3 years from now at the very least)
My old computer, which my wife is using now, has an i7 920 at only 2.67 Ghz, and it still runs games perfectly fine.
Honestly, it might be time to start considering overclocking her, because WoW actually said she didn't meet the minimum requirements! lol
(Game runs smoothly, like butter)
Right now I'm at 1.225v for 4.7, based on the model of .04-.05v per 100 Mhz, I could potentially reach up to 4.9 Ghz with 1.305-1.325v, which is a bit higher than what's considered safe, but I'm sure there are ways to stay stable with lower voltage by adjusting other settings. I could probably hit 4.9 Ghz at 1.3v.
(And for short-term bragging, I'm sure 5 Ghz wouldn't be out of the question, but not a daily OC)
But as I mentioned before and you said twice, it's probably best to skip water cooling right now. Maybe when I'm ready (2-3 years or so), I'll have the skills to make it work.
Thanks again for all the help, guys. I really appreciate the time you've taken to assist me in learning new things. From this post, I feel like my troubleshooting and overclocking skills have increased tenfold, haha.
Jordan1794: CompuTronix: Your memory speed is 2133 Mhz. I turned on XMP 1 in BIOS and it seems to have configured everything properly for that speed. At first boot, I thought it was only running at 1600 Mhz. Remember, your i7 4790K supports memory up to 1600MHz. Intel® Core™ i7-4790K Processor (8M Cache, up to 4.40 GHz) - http://ark.intel.com/products/80807/Inte...o-4_40-GHz This indicates that 2133MHz memory is pushing the memory controller on the processor to run overclocked, which may raise temperatures inside the CPU die. Some BIOS versions with specific motherboards can cause the processor to run hotter when XMP is enabled.

Turning off my XMP settings had no effect at all, lol.
The VTT voltage stayed the same. Temperatures were identical, CPU power usage matched, and so on.
I recall reading about it and making sure my RAM worked at 1.5v since Intel CPUs don't handle RAM above that (and definitely not above 1.65).
But now I'm beyond my limited understanding.
