i5-4690k clocking at 4.2GHz, Question/Vcore 1.088
i5-4690k clocking at 4.2GHz, Question/Vcore 1.088
hey, i just increased my "i5-4690k" to 4.2GHz on 1.088vCore with the "MSI Z97 Gaming 3" board.
is this actually suitable for that clock speed?
i ran some tests using AIDA64 and after 10 minutes the temperatures stayed between 55-61°C at full load.
for cooling, i use an air cooler called "Be Quiet Pure Rock Slim BK008".
p.s i’m considering lowering the vCore to around 1.050, but it caused a BSOD, so maybe the optimal range is closer to 1.060-1.080 at 4.2GHz. Or is it just a matter of luck?
what do you think about these chips?
Nothing is wrong with the clock/temps on that voltage and your cooler. However, if I were you, I'd extend the tests for about an hour or more, occasionally three times when I think I'm near my best settings, to better understand stability. Some might suggest testing more or less, and people do oscillate on that point, but I believe one or two hours works well for identifying solid ground. Prime95 (v26.6) with small FFTs can give a good sense, as can Intel XTU. If you run Prime95 on your processor, make sure it's version 26.6 only—can't stress that enough. Newer versions aren't very friendly to the 4690k.
The clock and temperatures on that voltage and cooler setup are fine. However, if I were testing, I’d run the tests for about an hour or more, sometimes three times, to better understand stability. Some might suggest testing more or less, but I think one or two hours is enough to identify a stable ground. Prime95 (version 26.6) on small FFTs can give a similar insight, as can Intel XTU. If you use Prime95, make sure it’s version 26.6 only, that’s crucial. Newer versions don’t handle the 4690k well.
Regarding the chip, it’s one of my preferred choices. My own build used the 4690k for several years and I really enjoy it. I even made other builds with those chips and would still recommend them if you can afford them. They’re smooth, solid, and dependable—perfect for what they do.
I previously ran my i5 4690k at 4.8GHz using 1.4 vcore, but eventually stopped due to performance issues and switched to a Ryzen 7.
Still managed to get through 5GHz despite the issue. It worked only on one channel, probably around 1.5 times the speed.
haswell cpu vcore must stay below 1.3 v otherwise issues may arise. At 1.088 it's working, but I recommend adjusting it to 1.29 v to explore further performance gains. Your z97 board should comfortably handle this setting and you can achieve around 4.5 from it.
The Paladin suggests the CPU core voltage should stay below 1.3 v to avoid issues. At 1.088 it's fine, but increasing to 1.29v might yield more performance from your Z97 board, which should still work well. You could potentially achieve around 4.5 v from it. Ran mine at 1.4v for two years without problems. After my 5GHz experiences at 1.5v, stability dropped to 4.8GHz, possibly due to the lower VRM voltage on cheaper motherboards.

Since OP relies on air cooling, I wouldn't suggest pushing to 1.3v. Pair that with the fact he can reach 4.2ghz at 1.088v—though a brief test shows a voltage of 1.25v or higher should suffice for further gains without generating excess heat. Remember OP, each chip behaves differently; only by testing yourself and understanding your limits will you know what works best for your hardware. Good luck!
