How do I decide which 3770k to keep?

post #1 of 6
Thread Starter 
Hello fellow overclockers smile.gif

So I bought two used 3770K's and I want to use one of them in my main rig and sell the other.

Id like to keep the one that OCs the best. Im planning on delidding the keeper.

So Ive been testing them out, but at 4,7 at 1.375v I hit like 95c. It does not crash and when its delidded it may prove to be very good. So what should i do? Just delid the coolest at lets say 1.3v? See which one will boot at 4.6ghz with least volts? Maybe 4.8 at least volts?

Thoughts? smile.gif

Ive never had this good a dilemma before, hope you all have some nice tips.

I dont wanna sell a delidded cpu to someone who doesnt know much about it.

First off don't let the CPUs go over 90c! They will just throttle down at that point anyway. Go back down to 4.6 GHz and see which CPU is stable at lowest vcore. I like to use XTU or Intel Extreme Tuning Utility http://www.intel.com/content/www/us/en/motherboards/desktop-motherboards/desktop-boards-software-extreme-tuning-utility.html

What program did you use to stress test your CPU overclock? Personally I wouldn't go above 1.35v for CPU longevity.

Firstly, what are the maximum CPU overclock you can do on both cpus without breaking 90C.

E.g

CPU 1:
4.8Ghz
1.36v

CPU 2:
4.7GHz
1.30v.

In this case I would of chosen the one that requires less voltage for a higher overclock.
