7700K clocking

[Dawelio]

Hey guys,

So I am now going to enter the world of overclocking, but not in the "usual" way to speak.

I have an 7700K, non overclocked and just got my new Thermolab LP53 cooler with an Noctua NF-A9x14 PWM from an Noctua NH-L9x65.

So I now want to undervolt the CPU as much as I can, since the CPU cooler is quite limited (the case I am getting is very limited in terms of CPU coolers and this is kinda the best there is to get out there for it), I want to try and get as good temps as possible.

I don't really need heavy OC's or so, hence thinking of either just sticking with the stock 4.2GHz or dial it down to 4GHz. Just to get better temps overall.

I wanted to hear with you guys, what you thinking of it all etc. Especially you all who have experience with overclocking and so on.

Dicey mentioned that he hadn't experienced anything over 4GHz to make a difference in games at 1440p, which is the resolution I am on.

What do you guys think here? Should I stick with the stock 4.2GHz or go down to 4GHz for better temps? Does/will these 200MHz make a difference in the real world anyway?...

Also what utilites/software do you usually run when doing these tests etc?... I've been recommended Aida64 for 30 min and Cinebench for 20 min.

Thanks guys,
Chrazey

To start i would stay at 4.2 GHz, and then try to undervolt it. There is no need to downclock if the temps are fine. Go down 0.025v at a time. Test for 5min, if it does not crash, then down one step. If it crashes add 0.010v until stable. Then stress for 30-60min. And then game

I'm happy as long as its stable in games, so i don't spend 24 hours stress testning, and i haven't had random crashes.

If you have a z270 board, you should be able to set an AVX offset. This means that the CPU normaly runs at max, but as soon as AVX instructions is sendt to the CPU, it downclocks by the offset. -2 = minus 200mhz. Its a way to get a more stable OC, but i would also mean a lot less heat. So i you just game then set it 200-500mhz under normal = less risk of overheating if you stat some thing with AVX

Thanks a lot for your post, very informative and really liked it.
Great point regarding the frequency speed and will do that

Yes, my apologies, I have the ASUS ROG Z270I Strix motherboard. Although, I have no knowledge of this AVX offset, sounds like something I need to look into further then.
As just doing the volting to the CPU, literally scares me a bit to be honest
