I5 6600k overclocking

[Legendaryx]

So I have tried to overclock my cpu and I ended up with 4.4ghz at 1.3v and for achieving 4.5ghz I need to set vcore to 1.35v is it safe for 24/7 usage? or should i downclock it back to 4.4ghz?

1.35 is generally considered to be the max you can go, but I wouldn't really recommend it for 24/7

Why not?,will it ruin my cpu?

increased voltage is a direct increase in heat output and heat it almost always the cause what kills electronics. so yes. i personally dont feel comfortable to run more than 1.35v 24/7 even on a custom loop thats the max im setting my voltage to. on air id stick to 1.25v maybe 1.275 depending on your ambient temperatur and cpu cooler.

I know but at 1.35v my max temp is 64-65°c while running aida64, is it considered a safe temp?

those temps are fine, but its not only your CPU. its the VRM too. like i said i wouldnt run it at 1.35v 24/7 but there are people that run 1.4v.its all about how long you want your pc to last. just keep cpu and motherboard degradation in mind. is 1.3v the lowest you can go for 4.4ghz? if you can get down to 1.25v on 4.4ghz id stick to 4.4ghz. 100mhz not worth the voltage increase imho, that would be your cpu's sweetspot

Yep 1.3v is the lowest I can go for 4.4ghz, anything lower than 1.3v will cause the aida64 test to fail and sometimes a BSOD may appear and the max temps are around 57°c while running aida64 at 1.3v

What motherboard are you using and did you do bios update? And cpu cooler?

I am using Asus z170p-d3 I haven't updated the bios yet and my current cpu cooler is an artic freezer 13

Motherboard is kinda low end but bios update should help you to slightly improve it and even get 4,5 stable with lower volts.

ASUS recommends a maximum of 1.35v on good air cooling, and 1.45v on good liquid cooling (360 radiator or better).  And yes, those are for 24/7 operation.  Source.  The first link in the first post will have some good advice for you.

 

But "safe" is determined by temperature as well.  You say your temps are 64-65°C in AIDA64 ... is that with CPU, FPU, cache, system memory, and GPU(s) selected, run for several (4+) hours?  If so, then yes 1.35v should be safe for your Vcore.

Yeah it stabilized at 65°c for one hour, only the gpu was unchecked during the test and I have found out that 1.35v wasn't so stable for 4.5ghz so i ended up increasing it to 1.365v

[MNMadman]

The reason I recommend testing with GPU selected is because your CPU temp will be affected when your GPU is fully heated up, on both air-cooled and liquid-cooled systems.

I just want to point out through my limited research on the 6600K. It seems that the OC'ing threshold of 4.5-4.6ghz has carried over from the Devil's Canyon/Haswell/IvyBridge era. My current rig is a 3570K. I could have got the Haswell but the first generation Haswell was not always hitting 4.5ghz. I see the same here with Skylake. I hope Intel will improve their fabrication process or start binning their K series CPU's so that the K series chips OC better. Intel reads these forums and 5ghz should be realized in the i5 & I7 K series CPU's.

 

I plan on building a Skylake system and will probably wait until the first refresh of skylake is rolled out. Historically the first batch of next generation Intel processors do not always OC as well as second batch or generation processors. It's been about 6 months since skylake release.

1.45 sounds awfully high
