update : didn't try using fatal1ty board as oredy success boot to windows with higher multi (52)
enable Cstate setting> no limit

what is the max safe Vcore. just wanna try how high this 2700K ES chip can go with safe voltage.
end up with setup in WC casing
very lazy to change the waterblock at first but when i saw the temp i was like
pretty low (40'C) compare to previous air cool (61'C)

Good to hear that you have found the culprit. I wouldnt change anything that i dont know.

Safe vcore? I think i'm the wrong person to answer this question lol. Dont go over 1.55v. Let it stay below 1.5v if possible. Stop stressing it at 1.52v on air cooling/ regular wc & try to keep temps below 80C to prevent degradation.

owh for now i only dare to go 1.45Vcore. i'm using custom WC, ek XT360 rad with 2x120mm corsair fan + 1X120mm Delta fan
last night ambient temp was very cold. idle 36'C, load 59'C. will try to stress tem on saturday as i have final exam this week

using 4.5Ghz only at the moment

Hey guys,

I am getting my new i7 2700K soon. I am looking at new mobo for it and i can see there are limited choices for mobo in Malaysia, any suggestions?

I am looking to OC my pc to 4.2-4.5 to be stable.

what i have now is:
2X4gb kingston KHX 1600 c9
2X2gb Corsair XMS3 1300 c9a
ATI 6850
Case
128gb SSD crucial m3
128gb sandisk extreme
few mechanical drives
520HX

Using Photoshop,Lightroom,SolidEdge,SolidWork,Pro/E most of the time.

I'm not dare to go 80c, keep my i5 4.3 at 40+ full load, 25+ idle

hi... My i5-2500k OC to 4.8GHz

Temp will upto 93+ MAX average will be 80+
isit stable? lol...

But that hot only when im Stress it...
for gaming not tat high...

What's your voltage?

i set it to 1.415V if i not remember wrong...

and im using http://www.arctic.ac/en/p/cooling/cpu/57/.html?c=2181 cooler... isit cooler sux? = =

air and wc are totally different

Sifu2 and Otai2, wanna ask is it possible for a proc to deteriorate within 2 weeks?
My 2500K was capable of doing 4.8Ghz with Vcore of 1.488V on air, prime95 stable 24 hours (blend test). But now it keeps getting error 0x101 or error 0xF4 when i prime only for 2 hours.

Anyway, pls refer to my sig for specs. Thx.

Just a quick Intel noob question since I just couldn't find anything related to what I want to know.

Can a locked SB use faster memory divider? For example i5-2400, can it be run at faster memory speed, or is the memory divider also locked? I know running faster memory speed barely does anything to improve performance, just asking though.

non-K like 2400 has limited unlocked multi, with unlocked mem OC

Hi Sifus,

Am facing a weird scenario here. OC-ed my proc to 4.0GHz with vcore of 1.150V. While running prime95 for awhile, everything looks good and temp max at 60c. But after that, I saw a big increase of temp until 85c and vcore at 1.360V. Kinda worried on the sudden increase of vcore and temp. Is this cause by the CPU LLC? I have the CPU LLC on level 2. Or any other possible cause?

Below is my specs:

i5 2500K @ 4.0GHz at 1.150V
Asrock z77 Extreme4
Seasonic S12MII 620W
2x4GB Corsair Vengeance 1333 RAM

The vdrop (vcore increased while on load) is indeed caused by LLC.
Higher LLC level is degradation level
Lower is safer & suitable for 24/7 operation
I'm not sure how ASRock LLC works but you use the LLC level 1 and vcore 1.36v then start start lowering the vcore notch by notch until a stable vcore is determined.
Stress test like prime95 does generate a lot of heat so a good cooler is recommended to prevent overheat issue.

From what I read, Asrock's LLC works the opposite way from the other mobo makers where level 5 nets you the least voltage compensation and level 1 the most. So, you're suggesting to lower down the LLC (Asrock's case, up the level)? Oh, forgot to mention that my temp and voltage only shoots up after the 7th hour of priming. That's why I feel it's a bit weird since for the 1st 7 hours, there is no voltage increase.

As for my cooler, I have 212 Evo with push pull fans.

LLC level which will give you lower vcore (vdroop) at load.
By rights as early as 20s you should see the core temp shoot up to its max (in your case 80c).
Be sure to use the latest prime95 + win7 SP1 and monitor the CPU usage thru task manager, should be full 100% load on all cores.
And next time pls post screenshot of the test to give some hints and info of your claim so that we could discuss further.
Good luck

Ok.
Maybe its the mobo's utility (ASRock eXtreme Tuner) which I use to adjust the fan speed on the fly somehow overwrites my bios OC settings. Will give it another go next weekend.
