Not possible to exceed 4.2 GHz for this processor model
Not possible to exceed 4.2 GHz for this processor model
I just completed my first PC build a couple of months ago and I have been attempting to overclock the i5-6600K in it lately. I've read numerous overclocking guides and I have attempted to put those into practice, and so far I've been able to get a stable OC at 4.2 GHz (only changing the multiplier, not the BCLK) with a cache ratio of 3.7 GHz at 1.300 volts. I'm watercooling it and so temps have been amazing, topping out at 60-61 C running Prime95 for 6 hours. Performance, considering the clock speed, has been excellent according to Intel XTU (1290 marks). No complaints there.
However, no matter how much voltage I throw at it (I've tried up to 1.450 volts and I'm not comfortable beyond that), I can't get it to reach 4.3. I've tried disabling XMP and raising/lowering the cache ratio, but I haven't been able to get it beyond that. Did I lose the silicon lottery, or am I making some sort of rookie mistake here?
For reference, here's my build:

Thanks in advance! I appreciate it.
I considered this after reviewing your system... I also checked another link on here regarding power usage and believe it should work. I’m aware that increasing the voltage draws more wattage, which could be connected to this issue... You might want to buy a higher-watt PSU, install it, and test it out. If you still don’t see improvement, returning it might be the best option...
I believe you've reached the limit of your chip's performance... There are mentions of higher clock speeds, but yours appears to be around 4.2... That seems like a decent build for the chip, though not the most impressive...
I believe you might have reached the upper limit of your chip... There are rumors of higher clocks, but yours appears to be around 4.2... That should be a reasonable setting for that chip, though not the most impressive. Adam
Fair enough... it doesn’t seem related to my PSU being rated at 500W, does it? It looks like a pretty low spec for a 6600K; most people can easily reach at least 4.4 GHz without any problems.
