I just increased my CPU's clock speed a bit, but I'm curious about the limits.
I just increased my CPU's overclock a bit (from 3.5ghz to 2.4GHz). I'm curious about how far I can push it without damaging the chip. It should stay cool at around 25°C when idle and up to 75°C during stress tests. I'm using RealBench, Cinebench, and AIDA64 for this. Sorry for any confusion, but this is my first experience with OC.
Voltage and heat are typically responsible for damaging chips. Personally, I lowered my 2700K to 4.5Ghz. I also reduced the voltage by a small amount, about 0.015V. I run IntelBurnTest for roughly an hour, not exceeding that time. If it remains stable for an hour, it should stay stable.
Short version
Voltage and heat usually cause chips to fail. I lowered the voltage by 0.015V and used IntelBurnTest for about an hour. Stability after an hour would confirm it's safe.
I'm still learning about OC and wanted to clarify what "undervolting" means. Also, how hot does your CPU get? I'll look it up later.

Voltage and heat are usually the main reasons chips fail. Personally, I lowered my 2700K to 4.5Ghz and even reduced it slightly, using a .015 Voltage step. I run IntelBurnTest for about an hour, not more. If it stays stable for an hour, it should be fine.
Apologies again, but could you clarify what "undervolting" means? I’m new to overclocking. Also, how hot does your CPU get?
I’ll look it up later. I just found a useful article: http://www.overclock3d.net/articles/cpu_...pu_vcore/1.
I use a water cooler, so my temperatures should be well within your range. Also, the 2600k model runs cooler than newer chips because of its larger process and solder between the die and the heat spreader instead of TIM.
You’re safe from touching the voltage, but if you want to push it higher for more MHz, you might need to increase the voltage.
Short version:
Leadbelly78 shares tips on voltage and heat affecting chips. He mentions using IntelBurnTest for short sessions, notes that undervolting helps, and talks about CPU temperatures. He also shares a link for more info and reminds others to avoid touching the voltage.
In short, you can overclock a Haswell chip to around 1.3 v without exceeding 90*C during stress tests. For regular use, gaming, etc., keep it under 80*C. As Kurz mentioned, it's heat and voltage that really damage a CPU. There isn't a strict speed limit. If you can maintain a steady 5.0 GHz within these limits, you're in good shape!

If I could keep my system running smoothly at about 5.0GHz, I'd be impressed, but I'd prefer a custom loop water cooler rather than an AIO one. Not everyone agrees on that.
Anyway, I'd really appreciate it if I could achieve stability at 4.5GHz. Thanks again for your advice.
