4790k 24/7 Overclock Question
4790k 24/7 Overclock Question
The maximum output I achieve with my 4790k on water at 4.7GHz and 1.258v is 1.258v, which is within the expected range. I'm curious if this level was considered acceptable and whether it's safe for regular use.
Also worth mentioning is the intense overvoltage situation. I'm struggling to exceed 1.2V on my 7700k.
Weird stuff here. My custom water loop isn't delivering 1.2v, but I still manage 5Ghz without much effort. The highest I've reached so far is 5.2, and I'm worried about going higher given my temps. You managed 5GHz at 1.2v—lucky chip! But I'm curious about your temps too. 1.2v is low, yet the frequency is really high.
My i7 4790K (delidded, using Coollabs liquid metal on both sides of the heat spreader) operates at 1.29v at 4.7G in air. It reaches a maximum of 60°C with Prime95 v26 and 78°C with Prime95 v28.10 when AVX extensions are enabled and no CPU limits are applied. Delidding significantly improved temperatures and was the most effective step I took for overclocking.
OnionKing shared their experience with a custom water loop, noting difficulty achieving 1.2v but success at 5Ghz without much effort. They mention reaching a max of 5.2GHz and express concern about temperature limits. They were impressed by the high frequency but curious about the thermal performance. The discussion references a game session with Star Wars Battlefront 2015 at 4k ultra resolution.
The temperatures are normal and the vcore is also okay. Usually, for Haswell refresh/Devils Canyon, the 'safe limit' for continuous use is around 1.3v or less. You're within that range, so there should be no problems.
OnionKing shared their experience with a 4790k processor running at 4.7GHz on water, asking about the acceptable output and daily usage safety. He also suggested testing Prime95 with AVX extensions to evaluate performance and stability.
