Hey guys ive got an i5 4670k that i want to overclock preferably around 4.4 to 4.5ghz without getting bsod. Ive got a gtx 1070 and the cpu is bottleneckibg it a bit so i would like to up my game. If u guys have a preload for ur i5 4670k can u share it with me or could u guys advice me on the estimated voltage and voltage input level and what increments to decrease or increase at. Greatly appriciated. Also at 1.3 core voltage with 4.4ghz is thatsafe for my cpu for the next 3 to 4 years?
Overclocking i5 4670k

80-90 degrees isn't a comfortable temp for a cpu
anything above 80 makes me very nervous.
TJunction temp for 4th gen i7 is 105 degrees C. That is the temperature where the CPU will aggressively throttle to preserve it's life.
Still, running it beyond 80 deg will still shorten it's lifespan if done long enough. There's no real 'rule of thumb' though and everyone will have their own buffer zones that they prefer to stay in.
You have a suitable cooler on the CPU, right?
How do you know that your CPU is bottlenecking?
No electronic component are the same. Whether you get a response from a person that has the same hardware, he/she may overclock a little more/less or apply more/less voltage to it. As a result may achieve a better/lesser benchmark score than you.
It is a bit of Silicon Lottery, trial and error with OC & voltage settings.
Obviously, the more stress you apply to it (o/c & voltage), the shorter life span of electronics you will get.
How about the rest of your hardware which can affect your performance, CPU cooling (Water or Air), Case cooling, PSU Wattage, RAM speed and amount and whether you have an SSD or HDD ~ 7.4K RPM, RAID 0 + 1 ….. etc….?
I would also strongly advise to back up your HDD if you have any personal documents as OC can affect the HDD stored info .. etc
Cheers
Well my silicon lottery is horrible im getting 4.3 with 1.3v so far but i haven't optimised it yet
If it were a broadwell chip I'd say 90C is fine but for anything that came after it I'd be uncomfortable with anything over 75-80C for long term use.
Easy fix would be to stick a waterblock on it, I've been running my 4930k @ 4.5ghz since day 1 and with a Corsair H110 on it and never seen temps above 65C.
I have a i5 2500k which is 3ghz stock but I run it at 4.5ghz with 10% voltage increase and the stock cooler. It goes over 90 constantly under load. Had it since 2012 still works fine.
I doubt a 4670k is bottlenecking your gpu. Have you used 3dmark or similar to benchmark your rig? What is your PSU wattage, you may have an energy supply shortage.
I think up to 90c is ok under load. With the voltage, again put the cpu under load and monitor the temp, if it keeps under 90c that's fine.
