Will undervolting affect clocks

Will undervolting my 8700k to 1.2v to 1.15v affect my clocks.

It won't affect them, but it may cause instability. Whats the point in undervolting it? 1.2v is not much for a 8700k, if I was you I would be pushing it to 1.300 and see how much GHz you can get out of it... I was pretty lucky and got 5 GHz 0 AVX offset with 1.300 volts.

Sadly my 8700k is a dud I can't push it far. But lowering my vcore to 1.15 has lowered temps by 8c (63c max) I did try 1.1v but because I have a bad chip it is not stable :(. Even if I could I would not overclock pretty much all games I play don't push my 120hz monitor at a resolution of 3440×1440

it can affect clocks

you got some headroom if you at 63C with or without the under volt.

Ok I'll do like 3d mark physics test at 1.2v and 1.15v see if there is a bug difference in performance

I changed my 3800x from stock, to 1.2V and my temps dropped DRASTICALLY, (73C to 56C under load). but my R20 score dropped from 4886 to 4568. So you'll likely lose some performance.

63 is very cool for load.... how are you stressing the CPU to get max temps?

 

Even if it is a dud, thats really cool. You can certainly push it a bit as you have lots of temperature headroom.

 

To properly test an OC or an undervolt, use Asus real bench for 8 hours. If it passes that, you can consider it stable. If it doesn't, your not stable. Undervolting on intel won't result in lower performance, it just will crash due to not being stable...

I was using realbench

Seems like undervolting hasn't affected performance.

I guess i just don't understand any of this. If your hitting 63c in realbench... your likely in the high 40's in games. This means you have a lot of temp headroom to overclock, like.... a lot. What speeds does it do at 1.35v? And what temps?

I'm hitting 63c in real bench with 1.15v. I hit up to 68c with the vcore on auto (seems to be a little above 1.2v) it can be cooler but that depends on how cool it is in my room

Right, I just, again, I am not sure what the real point of this is. That is very, very cool under a realbench load. You have ~25c of headroom to play with here, so why not try and overclock it a bit instead of undervolting it at stock clocks. If you can get it to 1.300v and maybe 4.8 or 4.9 ghz all core, that would be a solid FPS bump. Wouldn't be massive, but it would be some. Mid 80's in an realbench load is totally fine, low 60's is COLD. You bought a k series chip, let it rip!
