FX6100 overclocking Hyper 212 evo

crashing almost instantly 🙁 what to do. i spend my money on this cooler and it is serving same as the stock one

Just because you slap a bigger heatsink on a system, doesn't guarantee it will make a world of difference.

Tell us your system configuration, case set-up, ambient temperature, and measured thermals.

Also be sure to tell us your method of overclocking, and what goal you attempt to achieve.

yeah ! you are right. The base clock is 3.6 with turbo. So i want to reach to 4 GHz atleast. I am giving 1.25 volts. at 3.7 only, when i run prime 95, it crashes instantly ! :\
And i am increasing the multiplier, People have gone upto 4.2 with this Sink,
I have HAF 912, With 2 cabinet fans. what else do i need to overclock 300 or 400 MHz ? 🙁

Your case seems sufficient, assuming you meant you are still using the stock fans. However, you did not give some of the other information asked for: ambient (room) temperature, and measured thermals.

Hyper 212 cooler
Room Temp : above 30 Degree Celsius
anything else ?

 

[rohanrobby7]

on idle temp is 38 degrees.
And on overclocking it jumps to 56-58 and then crashes ( + 200 MHz )
on increasing 100 MHz it crashes while on 45 Degrees.

think you need more volts on your cpu. i know you cant generalise all FX cpus, mine uses 1.3v at 3.7ghz so you may need to bump it up a bit to increase stability.

Assuming you're reading the core temperatures, not just socket temperatures, you're still in the green for thermals. Even when using (hypothetical) 30 C as a baseline, your delta-temperatures aren't too bad; 8 and 28. That means your cooler is doing its job.

According to this page, your max core temperature allowed is 70C. That leaves you with a decent amount of headroom. Sadly, for whatever reason, it doesn't list the operating voltages for any of the FX-6XXX series processors. What I would do, is "un-overclock" your CPU, observe your voltages and record them. Whatever the max voltage it goes up to I would consider safe to, incrementally, increase to while overclocking. Be warned, increasing voltage also increases the heat, so I can not stress the word incremental enough.

As kind of a rough example to go off of, I have a FX-4170, which is 4.2 ghz operating at .8125-1.4125V with a TDP of 125. It is a factory overclock of the FX-4100 which runs at 3.6 ghz and has a TDP of 95. (Voltage range unknown to me at this moment.) I realize that this site (Tom's hardware) doesn't like going above 1.3v, but, who knows, your stock configuration might go slightly above 1.4v anyways. :\
