i75820k Crashing On Overclock
i75820k Crashing On Overclock
I have an I7 5820K at 3.3 GHz and can reach 4.5 GHz. I adjusted the voltage to 1.3 and set DDR4 RAM to 2400 MHz. The PC boots up normally, but when running an Intel stress test it freezes and requires a forced reboot. Changing the voltage to 1.300 improved stability by about a minute before it crashed again. What should I do? Anyone can help via Discord—why isn’t it working? I’m also an adhoglog on Discord: https://discord.gg/uDHETC
What motherboard are you using?
The i7-5820k works well for overclocking. I reached 4.6Gz at 1.25V stable, but for continuous rendering I keep it at 4.2Gz with 1.15V.
Peripheral voltages like vccsa/vtt and vccio tend to overvolt if left in auto mode, so you should adjust them.
Most crashes during stress tests seem linked to voltage droop.
A 120mm AIO won’t suffice. Choose a larger 240mm or high-end air cooler such as Silver Arrow IBE or D15. The i7-5820k generates a lot of heat.
Delidding might also be beneficial.
Instead of immediately increasing the speed, gradually boost the CPU and RAM one at a time until the system fails, then lower it slightly afterward. Unfortunately, performance differences differ between processors because of manufacturing variations. For example, an I7 5820k might be up to 1000 MHz higher than another, while a different model could range from 200 to 300 MHz.
i managed to achieve stability at 1.290 cpu volt and 4.3 ghz. however, the intel system test showed thermal throttling, so i adjusted it back to 4.2 ghz and 1.240 v or 1.230 v. everything seems to be working well. with a 120 mm liquid cooler, is that sufficient? would a 240 mm be better?

Ahad Beg shared his experience about achieving stability at 1.290 cpu volt and 4.3 ghz. However, after a thermal throttling test, he adjusted the speed to 4.2 ghz and voltage to 1.240 v or 1.230 v, which worked well. He mentioned having a 120 mm liquid cooler and questioned if a 240 mm one would be better. He also suggested upgrading fans and reapplying thermal paste, recommending Noctua fans based on his experience.
