i7-7700K overclocking
i7-7700K overclocking
I've been using a 7700K for a while now, roughly six months.
I've carried out some overclocking experiments after installing a Corsair H100i v2 liquid cooler.
I managed to reach 4.8GHz at about 1.3 volts.
It's not ideal, but it's the most stable voltage I could achieve.
A quick note: it doesn't get delidded and at 4.8GHz with 1.3V I maintain a steady 88°C on Cinebench with quiet mode active (full CPU load).
My main concern is whether to use static or adaptive voltage.
Power costs here are very low, so that's not an issue.
I'm new to overclocking but have done some basic work before. Others say static is preferable for stability testing.
I've attempted 4.9GHz three times at the standard voltage and it crashed immediately (honestly, I'm still learning).
I haven't pushed beyond 4.8GHz with higher voltage, but I achieved a steady 4.8GHz around 1.3V.
Currently, during idle (while writing this), it's running at about 50°C in quiet mode. It sometimes spikes to 70°C unpredictably, which worries me (especially during idle).
When I ran benchmarks on an Intel XTU, the peak temperature reached 99°C, so I didn't get to see the full picture.
I'm still unsure whether delidding is worth it because I don't fully trust myself. People claim it's simple but can easily ruin things.
My second question (a bit) is about the necessary components and where to source them, plus what to do and avoid if I decide to try a 5GHz-5.2GHz setup.
50c at idle is significantly too high. The OC settings seem unstable. Consider reducing the OC or adjusting the voltage. Your temperatures should stay between 30-35 at idle, 45-65 during gaming, and 65-80 under stress testing (just a general suggestion). Keeping temps below 80°C at your selected OC is recommended. Static voltage helps check stability, while maximum heat at a fixed voltage can boost clockspeeds but also raises temperatures.
Why do you want to delid the CPU, or why are you even considering it? It's not 'that' easy and should be done ONLY with a great deal of knowledge of what you are doing, and what you are trying to achieve. if you are only trying to achieve some benchmark metric, I wouldn't bother. At stock the 7700k is a great gaming CPU. With a moderate OC it's still a great gaming CPU. Deliding might get you a few hundred mhz extra, but with better cooling, and an inate understanding of what you want, deliding is pointless. It won't get you some kind of insane performance leap, because you delided. IMO, you are much better off getting a stable, consistent, repeatable OC, that will give you a decent performance boost. Here's a great guide for OC'ing. Read it. I think you will see some reference to deliding and it's effectiveness. I would be more concerned with getting your current OC stable, temps below 80c, and with as low voltage as possible. Getting it right is key. At those temps, you will mostly likely experience random shutdowns, CPU thermal throtttling etc. https://forums. You're saying it's stable at 4.8 1.3. Your temps are too high if they are close to tjunction. Try Prime95 small ffts. This will test only the CPU and cache, and will indicate any instability for a given voltage. If any worker threads fail at your current settings, you know it's not stable. Which i suspect it isn't at such high temps. Also, 5.2 for 7700k is unlikely. Even deliding. You will need to look possibly at a better mobo with better and more power phases. It's possible you might need a new PSU as well to accommodate the extra power draw. There is a lot to consider.
Temps stay acceptable below 90°C. And even under heavy load they don’t climb that high. I’m using a Gigabyte motherboard with a Z270X socket, and the odd thing is that after resetting the clock speed, the CPU remains at 50°C during idle. I’m not sure why.
Are you certain the Corsair is correctly positioned? Perhaps re-seat it again and reapply thermal paste. Your temperatures remain high, and if they haven’t changed even with stock coolers, it suggests the cooler isn’t fitting properly. It could be slightly misaligned in one area or the paste hasn’t fully cured yet.
It's set up correctly, I'm sure. I didn't have to install it, so I wasn't responsible for it. The reason I didn't want to install it was because of this concern. If something goes wrong and it leaks, it will be my fault. I just hope the person who installed it did a good job.
So you're only assuming it's installed correctly, as you didn't install it? I would definitely consider what keith12 has mentioned and verify correct installation. Its a very quick and easy thing to do. It will not leak if installed correctly or not as it's a sealed unit, and a leak would be a defect. There is a chance like mentioned that it's not properly torqued down and not making good contact. Again an easy check and fix. Grab some thermal paste and give it a go, you may see very good results. If you're not comfortable with cooler installation, I would not even consider delidding.
