Actually i have no plan to OC RAM, but well, running my RAM at 'default' 2400Mhz already mean i OC from Haswell point of view.

Regarding temp drop after delid, -30'C is just an absolutely best case can achieve, i doubt everyone delid can get the same result. I search the forum, mostly drop around 10~ 15'C only, correct me if i'm wrong. I just worry lesser gain when i delid (<10'C drop), not worth if like that.

Anyway, yesterday i got frustrated by the result, so i pump 1.4v and clock to 4.7Ghz, can boot and running GRID 2 without issue. Today will try to hit 5Ghz with this voltage.

Normal TIM will reduce up to 20C. Liquid metal TIM like Coolaboratory Liquid Pro will give another 10C improvement.

Yesterday just bought a table vise. Now waiting for that moment of indiscretion then will do it....maybe a year later . I will buy G3220 as a backup before i do it. Now just settle with 4.3Ghz with 1.22V.

Anyway, read the forum about temp reduction after delid, it actually depends on originally how loose the contact in between IHS and die, if the gap already small, delid and reapply TIM might only give 7-10'C reduction. 30'C just a rare case.

hi guys. im trying to find the lowest voltage for idle for my 4670k. im pretty sure the default (standard) value is 0.8v at 800mhz.

i set the adaptive vcore at 1.1v with offset -0.125v. multiplier is at x38. during idle, my vcore is 0.703v at 800mhz. offsetting to -0.15v causing system hang when launching programs (skyrim tested).

so i need to gather a bit data from you guys, what is your lowest volt for your chip?

coolkwc,
try these settings and post back with temps.

CPU Clock Ratio - 44
Uncore Ratio - 4.2
Intel® Turbo Boost Technology - Disable
Hyper-Threading Technology - Disable
System Memory Multiplier - 21.33
Channel A Timing Settings:
CAS Latency - 11
tRCD - 13
tRP - 13
tRAS - 30
CPU VRIN Loadline Calibration - Extreme
CPU Vcore - 1.260

just want to ask, what is the common voltage for i5 4670k at 4.0ghz? does it need to manually set the Voltage if overclock speed at 4.0ghz?

Average is 1.0-1.15v depending on chip.
You can have it set to auto but the BIOS might supply it excessively. So set it manually is better than letting mobo to decide for you.

Hi guys, this thread is opened for the recently launched Z97 chipset as well.

Who will be the first Z97 overclocker in this thread?

U, no doubt about that.

eh bro thought the k series delayed to end of the year??

They will released 'OC enhancement' Haswell by mid year, they will 'improve' TIM for this unlocked chip, seems like maybe they back to solder TIM...

Bought an i5 4670k chip last week, first oc attempt.
Refer photo attached, 1.52v vcore WTF
Need time to explore more

Haswell K is set to be released in 3Q 2014.

+1

Actually it's not really bad when Haswell can do 5.0 with full cores/threads.
Nice wallpaper btw.

yeah but this time i aint gonna blow 20k on cpus and made a loss of 2k selling them at a discount.

its not the tim is the only issue. Some of the proc i had.. their vid voltage was the voltage for the multiplier of 39. I was like wtf. 0 headroom

Yeah same here. Lots of money and time spent for chip binning on 3770K and 4770K end up buying used ones for 2x price lol.

Took them two gens to fix that overheat issue. Hope no more new issue arises on the refresh chip.

This is my final OC result, i think i will settle with this speed. Only validated by AIDA64, LinX, IBT, Prime95 result will no doubt out of the question and i dun need that as well. Will try and see stability during daily usage/gaming.
