Curious to know how hard I can push my i7-2600k

Hallowhead · Feb 23, 2017

I currently have it overclocked to 4.5ghz never had any issues at this clock speed. I am now wondering what speeds I can push this bad girl to without losing stability. I have a cooler master v700 power supply, so I should have plenty of juice to toss it. My graphics card is a ASUS rog strix RX 480.

Let me know what you guys think
Thanks

Cooler Master doesn't make a V700 that I'm aware of. Do you mean a V750? If so, your power supply won't hold you back.

I need to know what motherboard and CPU cooler you're using as well as your case fan config.

it's discontinued

I have a hyper 212 EVO, looking to potentially get a simple water cooling unit as I am going to probably upgrade my CPU soon

I have an asrock x68 extreme3 gen3 motherboard

Please don't get an AiO liquid cooler. I'll explain why below.

Your motherboard has excellent power delivery systems with good cooling. Great choice in boards.

Remember how I said the board has good cooling? That only applies if there's airflow over the socket. AiO coolers put the pump at the socket and move the fan over to the radiator on the chassis. This starves the area around the socket for airflow and may cause your power delivery systems to overheat, resulting in unstable voltage output and possible (yet highly unlikely) damage to the CPU.

This makes sense are, are there any good water cooling options than?

Also how hard you think I can push this chip ?

The Cryorig A40 aims a fan at the VRM heatsink to the left of the socket, but your board also has VRMs above the socket. Seriously, just get a good quality air cooler.

As for how hard you can push it, I've seen 5GHz stable with the Be Quiet! Dark Rock Pro 3 and other high end CPU air coolers.

I have a i7 2600k OC 4.5ghz and it will run anything I throw at it.
I have it paired with a GTX 970 and I feel like this GPU is the bottleneck in my system !

I bought an AiO to see if it worked. It did. I got to 4803MHz (102.2x47, Vcore 1.544, Power 117.8W). But two things happened. While it passed Intel CPU Burn Test, real applications would fault, and I started to smell anti-freeze. I found no leaks, but removed it. Also it was hot at 95C (throttle is 98C). I am now back to a sane 4.5GHz and super cool on air. It was interesting to try. Most surprised that while passing Burn Test but real applications (with more instructions) would fail. At 4700MHz it ran all applications.

I don't believe that passing just one stress test means it's stable.

I usually recommend stress testing with Prime95 V26.6 for 24H and then AIDA64 Extreme System Stability Test for at least 1H before assuming the OC is stable.

I don't think any stress test is complete as they use only a few of all the processor instructions.
