Question To how much should I overclock I5 2500K with Hyper 212 Evo

Hello.

As I said in previous topics, I decided to buy Hyper 212 Evo for my I5 2500K.


I want to overclock the CPU, but I don't know to how much I should push it...

Any ideas? Suggestions?

Armoredhound,

Some overclock higher than others, so there's no "formula". You might be able to reach only 4.2, or as high as 4.8, or anywhere between. It all depends on how good an overclocker your particular CPU sample is. No one can predict that. We can only say what is "typical" for an i5-2500K, which is roughly 4.5'ish to 4.6'ish. The only way to know is to go ahead and overclock it to see what yours can reach.

No two processors are identical; each is unique in voltage tolerance, thermal behavior and overclocking potential, which is often referred to as the "silicon lottery".

Overclocking is always limited by two factors; voltage and temperature.​

For 2nd generation Sandy Bridge processors such as your 2500K, the maximum recommended Core voltage is 1.375, and the maximum recommended Core temperature is 80°C, so you'll need a decent CPU cooler. Whatever highest stable overclock you can achieve without exceeding 1.375 Vcore and 80°C will be the best overclock for your particular 2500K.

Although there are plenty of guides available on the Internet to help you, I suggest that you start here:

Isn't 4.5 like... too much?
Not at all but as CT pointed out, it'll depend on a few factors. But i did give you a rough estimate of around that level, doesn't need to be at 4.5, it could be maybe 4.3 or if you're lucky, perhaps some other higher number.

What's the reason for OC? Have you considered looking for an upgrade? If not a complete overhaul, there could be good deals on second hand i7s on the market ie 2600/2600k, 3770/3770k. If you play other games besides CSGO, the extra threads go along way with these ancient chips.

@boju, @CompuTronix

I have been clocking my 2500k on P8Z68V at around 4.5GHZ at 1.3500V with a Hyper 212 EVO. Below are the snaps of the tweaks in the BIOS when at 4.5GHZ.



It idles at around 41-43C at 1.6GHZ however, when I tested P95 Tests at 4.5GHZ for 6 Hours without any issues. I got temps of about 75-77 C Avg during these tests.

When I was stress testing the CPU the voltages spiked to 1.360V from the base of 1.336 as well where as I have set the Voltage to 1.3500V. And I find the Temps or Voltage shows different by different applications like GPUZ and HW Monitor etc Temps Sensor or the Voltage Sensor.
My Question : Why is this happening even when I set the voltage to 1.3500V? If this based on the Speedstep Option that I have enabled in the Bios which one is correct? Volts of 1.368V, Are they in safe Range and can be used for daily usage?



But when I try to Increase the Multipler from 45 to 46 or 47 keeping at the same voltage i am getting BSOD with P95 tests.
My Question : So, Should I try increasing the voltage to 1.375 and then try increasing the multiplier to 47 or 48? Will these voltages damage the CPU or motherboard? Should I not try doing that? Are these voltages in safe Range for daily usage?

Your feedback will be highly appreciated and will be very helpful.
TIA:)
