optimize i5 4690k at 3.5ghz with corsair h115i for peak performance
hello
i'm checking how much i can push my i5 4690k with the aio corsair h115i and corsair 850rmi psu.
currently at 4.5gh vcore 1.25v, max temp is 55c.
trying to reach 4.6 with 1.26-1.265 passes stress limits in cinebench, but freezing occurs during games like pubg or fifa when temps drop below 65c.
should i increase the voltage?
how far can i go?
that depends on both the chip and the motherboard it uses. each chip has its own capabilities in terms of voltage and performance. the motherboard plays a role in supplying the necessary power. a reliable one ensures you get the power you need, while a lower-quality one might not deliver or maintain it properly. use it as far as possible within its stability limits, that’s how far it can go. there’s nothing you can do to change the chip’s ability to handle higher voltages or speeds. it’s known as the silicon lottery for a reason.
Sadly, with the Ivy Bridge there are more issues than successes when it comes to building a top-tier overclocker. You're lucky if you manage to reach 4.5 at 1.25 GHz. When boosting the Ivy Bridge CPU, make sure your RAM is running above 1333 MHz; lower it back to 1333 and attempt 4.6 if that doesn't work. Don't rely solely on Cinebench scores after the fact—run a blend test in p95 or similar in AIDA64 for at least an hour without any crashes. Keep an eye on your temperatures, as Ivy tends to run hotter than others; hitting 90-95°C during stress is acceptable. After confirming your limits, fix the clock and gradually increase RAM speed one preset at a time.

Once you confirm the limits, fix the clock and gradually increase RAM speed one preset at a time. It's Haswell and should easily reach around 4.7 GHz.
