i5 4690k 4.2ghz unstable
Hello fellow overclockers. Over the last two weeks I've been facing challenges with CPU overclocking. I've studied every guide and watched every video, yet nothing seems to work. My adjustments have included changing almost every setting, setting the multiplier to 42 (4.2 Ghz) and the ring ratio to 35, while leaving the voltages on auto. According to what I read, auto voltage consumes too much power, but even with auto (vcore at 1.2 volts), the overclock remains unstable.
I can boot into Windows without issues and run AIDA 64 for extended periods, but when attempting games such as Dishonored 2 or Company of Heroes 2, the game crashes unexpectedly.
Did I overlook something extremely important?
You probably didn't miss anything, it is always the silicon lottery. Benchmarks and stress tests are not representative of what the CPU will behave like when gaming. You have two options:
1) if you feel that voltage should not to be increased further, simply reduce the overclock by 100 MHz and try again. If it doesn't work, reduce again by 100MHz. Rinse and repeat until you find stable frequency.
2) keep the frequency, but increase voltage slightly if you still have some headroom
Of the above options, I would rather go for lower and clock than unstable/hot CPU. But that's just me
😉
hello mattie,
i encountered the same issue with the i5-4690k at 4.5Ghz using a vcore of 1.250 volts. it passed all tests, but playing Battlefield 1 caused instability. i then adjusted to 4.0Ghz with a vcore of 1.112 and everything worked again. here are my stats after the 5-hour stress test.

Yeah, I guess I will have to learn to live with it as far as this chip is concerned
🙁
At some point I honestly thought I did something wrong as nearly everyone seems to be hitting 4.2Ghz at around 1.10 - 1.15 Vcore...
I could push the voltage to 1.25 Vcore, but quite frankly I find that kind of voltage ridiculous for a measly 300mhz, so I'll probably stick with 4.0 Ghz on stock voltage (which seems to work).
Hello mattie,

Wow, those temperatures are quite impressive! Would you consider aiming for 4.4 or 4.3Ghz during your first overclock? Or is stability really only guaranteed at 4.0Ghz in Battlefield?
I'm targeting 4.5ghz which seems impressive, though I understand 4ghz offers more stability. This keeps me here with optimal temperatures and a strong CPU.
