I5 4670K overclock

post #1 of 4
Thread Starter 
Hi Guys, looking for some advice please....

I've been running on the stock cpu cooler for the last 2 months so I'd therefore held off doing any overclocks. Today however I've just purchased a H100i and on my first attempt to reach 4.2ghz I had to up the voltage to 1.3 to just enable me to boot into the OS. It did seem stable for an hour whilst running prime95, but I noticed the voltage was going up to 1.424v. On further investigation I realized I'd left the voltage setting to adaptive rather than manual, which I believe is not very safe? Anyway, I changed it back to manual mode for the stress test and It blue screened again.

Leaving my voltage at 1.3v I lowered the target to 4.1ghz but it blue screened after 10mins, so I went down to 4.0ghz at which point it now seems to be stable (for the last 2 hours anyway). I guess my question is...considering everything seemed OK at 4.2ghz in adaptive mode but with the voltages going higher than 1.3v, Is it safe to increase higher than this or should I just bite the bullet an accept I've got a below par overclocking chip?


Is 4.0ghz at 1.3v with average temps at around 60c whilst running a stress test acceptable? I'm guessing I could up it to 4.2ghz in adaptive mode but would I see crashes in game if I couldn't do this in the manual mode? I was even seeing the core voltage rise to 1.425v during the stress test when the target was only 4.0ghz, albeit this was again in adaptive mode.

Just a little confused now on how best to leave things, any advice would be appreciated.



This is a screenshot whilst running @ 1.3v (adaptive mode) with a target of 4.0ghz.

Try disabling C-States and have Enhanced Intel Speed Step Technology with Intel Turbo Boost on. Also set your Load Line Calibration to 50% / Medium. These settings should help.

Thanks for the reply, Should this enable me to lower the voltage whilst keeping at 4.2ghz? What sort of improvement should this give.

from what i read all around the forum lower ur uncore to 33 or 34 ,and dont OC ur ram
just start OC CPU .
and your cpu is using alot voltage compare to 4.0 Ghz
