I5 4690k Overclocking Help

[benorton]

i have a 4690k and a h105

i was wondering if anyone has good clock speeds and voltage to start working up from

also i dont know what the max voltage i should never pass is so if anyone knows then please tell me

thx

do small increases and go to failure, then up the voltage until stable watch temps.

starting from where and what max voltage should i go up to

I am going to suggest you different voltage and multiplier for mild, medium, and high overclock. Before starting to overclock, adjust the multiplier setting to all cores. Put your voltage delivery to manual.

 

For a mild overclock:

Multiplier: 40

Vcore:1.20

 

 

For a medium oc:

Multiplier: 44

Vcore:1.23

 

For a high oc:

Multiplier:46

Vcore: 1.25

 

 

Wheter oc you choose to do, do about 2-3h of testing for each attempt. If your pc blue screens or the stress test shows instability, increase voltage. When stress testing, keep a close look at temperatures but with that cooling you got, you should be fine. If you find a oc where your pc is stable, just trying to bump your cache multiplier closer to the core multiplier that you set for your oc. For example, for a core multiplier of 44, try puting something like 41 or 42 (you might need to adjust cache voltage though. Adjusting the cache multiplier is optional though).

 

As a temp monitoring, I recommend Coretemp or HWmonitor. You should always have Cpuz up during your testing. For the esting software itself, you can use Aida64 or Prime95 but dont forget to have your voltage delivery set to manual cause if it is on adaptative, Prime95 is going to be a bitch and push to much voltage to the vcore.

 

Hope this helps you

I managed to push my 4690k to 4.4 @ 1.25 volts with a h105. I used the Intel Extreme Tuning Utility for stress test and benchmark (a lot of people recommend against using prime95 or Intel Burn Test for stressing this chip) and maintained stability with max temps of 75c. I'm running in an Enthoo Pro case with stock fans. I started at 1.200v and pushed to 4.2, then moved up to 4.3 and got stable around 1.23, finally pushed to 4.4 and got stable at 1.25v.

 

Consensus seems to be 1.3v is the max to keep up this chips lifespan.

Try 46 multiplier @ 1.3V. If it passes stress tests and temps are good (under 90C), raise the multiplier by one and test. If it fails then raise the voltage until temps are too high while absolutely keeping it under 1.35V. If 4.6GHz @ 1.3V fails then drop the multiplier until stable then try dropping voltage as much as possible while maintaining stability.

I got mine to 4.6 with multiplier at 45 and base clock at 102.0 voltage at 1.29 and I'm having a difficult time with temp. My temps are not suitable to my expectations. I've read time and time again regarding that higher voltage and higher temps will significantly shorten lifespan of Haswell cpus. Also seeing raising voltage drops temps but either way according to several senior members of not only this forum but several others. So I myself am stuck with this issue.

Particularly anything 1.3 and above with voltage temps are with cpu under max stress 212f
