Vccin / cpu vrm voltage

[lemontea]

I have i5 4690K overclocked and stable and i want to low the temperature by decreasing vccin like anybody did. The default is 1.9v , i try to drop it by 0.050v until unstable or BSOD ... but itsn't, now the vccin is 1.6v and stable with prime over 4 hours, im confuse right now.

From how you explain it, i's say you are trying to squeeze to much power out of something without giving it much to work with. When you are overclocking you don't wanna turn down the voltage, it is actually the opposite. Allowing it more power to OC better

Lower your core clock soem and then try to turn down the voltage and it should be fine

What are your reg temps btw?

I got 4.4ghz 1.250v max temp 83c ambient 29c-30c with p95 26.6 , i want to lower it around 75-80c . But now i'm confused whether i need to lower the vccin a bit or no. And i don't know what happen if i lowering vccin too much since no sign of instability. What the bad things could happen when i lowering too much?

Sorry about my language because i'm from jupiter

Your better lowering the core voltage to reduce temps rather the. Vccin

Lowering your core voltage would be best as ccampy said.

and about your language...I am going to take it as you don't mean Jupiter the planet.... I hope

I can't lowering my core voltage because that's the stable voltage.

Nothing besides lowering the core voltage is going to impact temps in a significant way, anyway your temps are fine how they are, under real world usage you won't be seeing those kind of temps.

Only thing left to recommend is to get a aftermarket cooler. Hyper T4s are quite cheap if you don't wanna buy a Hyper 212 Plus or EVO which gives quite more significant performance

Yeah 80+ is ok under prime95 just want a bit more lower if i can, that's why i try to lowering vccin if affecting the temperature. Btw I'm using noctua u14s.

Those temps are not good to have that cooler! that is one of the best fans on the market and your still getting temps that you'd get from the stock cooler. Maybe your pushing you CPU to far?

Not really, i got average chip i guess, so i need 1.250v to run 4.4ghz rather than 1.2v for 4.5ghz or more like everybody did to this chip and 1.250v just like limit to the hotter temp, if i turn down to 1.240v-1.245v the cpu temperature will decrease significant compared to 1.240v vs 1.230v but unstable . My ambient temp around 29c-30c .
