Then your i7-4790K with turbo is limited to 4 GHZ?

My default .....4.4 GHz with XMP enabled....VID 1.18V



Edit:

4.0 GHz ....VID 1.05V

nice info bro.
Was runing Vcin/vrin at 1.98v @ 4.7ghz. Did a quick test, IBT stable @ 1.6v vrin, Gonna further test later. Temperature wise, there's no dramatic changes, still at high 90c range when doing IBT stress run.

i7-4790k @ 4.7ghz Vcore 1.205v / Vrin 1.6v / Vring 1.1v

i would wait doing before such

wait for more results, voltage readings on the cpu etc..

cause having a starve state on the cpu voltages will definitely cause it to degrade faster.

but ures should be ok.

i so far follow the intel vccin spec

boot at 1.7v
operate between 1.65-1.8v (without loadline etc)

Sorry newbie here, is this good enuf for 4.00Ghz G3258 ? I mean the setting and all Vcore etc..?

Vcore could be reduced. My G3258 ES sample needs 1.2V for 4.0GHz:



Review: Intel Pentium G3258 Anniversary Edition

Thanks buddy Will reduce the vCore later on.

Why my g3258 cannot boot?mobo asrock z87m pro 4,help

Liquid nitrogen....

before use devil proc.. need reflash bios latest bios 1st using old haswell proc

LinX 0.6.5-11.2.0

https://www.mediafire.com/?ii62gs08uy7y947

- with latest Intel Linpack binaries (ver. 11.2.0.003)

Lol wht a hassle?
Dont they figure this would troublesome us as user?

Actually Intel doesn't officially support G3258 & Devil's Canyon on Z87 but Z97.
Motherboard vendors dislike Intel's greedy move and released Z87's BIOSes to allow compatibility with these new CPUs.
ASUS provides BIOS Flashback feature on their ROG boards so that you can "blind" flash the BIOS without the need to have the CPU installed.

Just have some testing on my new rma hynix cfr, seems cannot compete with mfr and psc chip
Any hynix user here?

wta, just gotten h100i. i notice after startup, the temp is around 70C and slowly going down until <40C.
but sometimes it will shootup to more than 60C on normal process = google chrome then load video.

below i try to prime95 and instant hit 100C within few sec.
any thoughts?
will try to resit cooler 2moro morning and get back to here. search google and quite a no. of h100i failure case.

**no such problem on previous cooler - Phanteks PH-TC14PE
***Setup = 2 pull SP120 @ 1.6k RPM. Rad top / fan btm.

Possible that the block was not sitting on the top of the cpu properly.
Hope you rectify it asap as your cpu will burn out easily.

re-sit it and apply mx-4. on stock clock / voltage. it hit around <75C on prime95 blend test.
will play around with different fans and settings.

what bother me is the cpu temp can reach 75 but the rad temp is just 5C increment - 30C to 35C.

looks pretty normal if you ran those stress test. Especially when you ran Prime which support avx instruction.

My i7 4790k@4.7Ghz/ 1.207vcore hit 99c within few second when running IBT/prime 95 and radiator gets real warm quickly.

For real world... just test it with your favorite games, temp shouldn't go over 60c for a non oc proc which is cooled by aio.

I'm getting under 53c running d3ros. Btw i'm using corsair H105.

what software you use to monitor your internal temp while gaming? my rivatuner cause Corsair Link to crash. only by disable ingame monitoring on riva, then the Link is working fine.

thxs alot for your input. i guess when the temp hit 100, i forget to notice the vcore on the cpu-z as well which is above 1.2v.
this is my first time to go in-depth OC a haswell cpu. previously on amd 1055t, its fairly simple and straight forward.
from my read, it seems that no matter what vCore method you use (except Manual), it tends to draw more power than require (on load). and as your said the software use avx instruction override all mobo vcore setting.

will play more and suck up most of the info/guide on 1st page. glad that my temp back to normal and your experience relief my worries on my virgin experience hitting 100C

I'm using hwinfo64 v4.4 to monitor my temp and msi after burner for gpu.

my humble attempt:
