What a great club..!
Hi everyone, i a newbie of i5 2500K

Just got my rigs few days ago, finally settle down all the cable management and software.. and it's time to OC kaw kaw !!
Currently i'm using Asus P8P67 + 15 2500K, after reading the user manual, i decide to switch om the TPU button on the motherboard, and after log in to windows... wuuulaaa...4.3Ghz without going to bios and set anything
Second stage, i try the TurboV auto tuning (from Asus), set extreme and go
after log in the windows, still 4.3Ghz, but wait a minute.....it increasing 1 multiplier each time, once it hit 4.8Ghz i decide to stop there, cos i can read the temperature goes up to 72C..

Now i wanna play around with manual (BIOS) OC, try few times, but unfortunately i got blue screen, dun understand y..
I set multiplier to 43 with BLCK 100.3, 1.2 Voltage and leave everything auto
still blue screen, any SIFU know why ah?

I never check the BSOD code, is'it someway around the blue screen?
I saw my temperature raise up to 72C, is'it ok for 24/7?
There is a lot of setting, such as Load line calibration, VRM frequency, VRM spread Spectrum, Phase Control, Duty Control... is'it fine to leave everything in AUTO?


Will try again tonight, thanks for your help

Thanks mate, full stress 4.8Ghz @72C/lower will be my next target
However i'm happy with 4.3Ghz 1.17v for 24/7, but i find out that when i running Cinebench, 3 core working very fast, but 1 core like freezing/extremely slow
Anyone have this issue?

running linx 0.64?

Is'it a benchmarking software? will download and check
BTW i've check my BSOD, 00124 something, then i increase my voltage. It really works..credit to owikh84

Run Cinebench 11.5, with all CPU i got 7.06. Quite happy with the result

currently im trying for manual OC for y P8P67 i5 2500K, follow all the guide from the threat, what i got is stable 4.3+ ghz, BUT no under clocking.. my CPU just remain 4.3 Ghz even in ideal.. anyone know why?
I turn on IEST and EPU, but it still only working working in 4.3ghz
my setting is:
AI OC Tuner: Manual
BLCK : 100
Turbo Ratio : 43
Internal PLL : Auto
Load-Line Calibration : Ultra High
VRM Frequency : 350
Phase Ctrl : Extreme
CPU Votage : 1.22

When i log into windows, it just working at 4.3ghz even ideal
any idea why it won't down clock to 1.6ghz when ideal?

thanks

Thanks for the guide mate, very helpful

Haha, i'm wondering about the setting just now.. then i try all the setting, finally happy with Balance & Power Saver
Now my CPU ideal temp is 19C only

BTW, will this setting affect my processor speed?

Thanks to OWIKH84 & others forumers, I manage to get 4.3Ghz @1.23v , 43C Full load
And idle 1.6Ghz @19C

Here's my setting
Ai OC Tuner : Manual
BLCK Frequency : 100.0
Turbo Ratio : By All Cores in OS
Ratio : 43
Internal PLL : Auto
Load-Line Calibration : Ultra High
VRM Frequency : 350
Phase Control : Extreme
CPU Voltage : Manual (1.23v)

Since the temperature working under 45C, i'm about to OC further until it hit 60C @ Full load

lets say I disable all those power saving stuff and keep the cpu at 4.3Ghz, will it faster then i enable power saving (1.6 idle, 4.3Ghz Load)?

Attached thumbnail(s)

ic, so will stick with this setting.
I got 0.9V @ 1.6Ghz & 1.28V @ 4.3Ghz, (offset -0.05)

No you don't have to, heatsink just part of hardware & Windows is software. nothing to do with it
I'm not familiar with Gigabyte Bios, but as far as the K series is concerned, you just have to play with CPU Multiplier (Ratio)
Exp: the FSB should be 100mhz, your multiplier is 34... so end up you'll get 3400Mhz
Increase the multiplier to 40 you'll get 4Ghz.

Increasing CPU voltage normally is needed for OC above 4ghz
Just play with it, you'll find out what is suitable for your rigs

Any BSOD? what's the temperature in full load? Which heatsink you using?

apparently heat is not the issue, then you have to play with vcore

yea, i'm also a rookie.. but this threat help alot.. dun hesitate to ask question here
beside vcore, phase control, VRM frequency, load-calibration and etc also will affect your OCbility
dun be afraid to increase vcore, just OC kao kao
Normally when you set Auto Tune, the vcore is a bit higher then needed
take it as a reference, and lower it down bit
Check your BSOD, you'll know when to increase vcore

next year 1st quarter ivy bridge should appear, then that will be a significant improvement.
Not so optimistic about this Sandy-bridge-E
Perhaps x79 will be the DOA socket

No point to make huge damage for your wallet if you don't need such performance

Mind telling me what the vcore and temp in full load for 4.7?

73c huh, i think sandy bridge can handle 80+c, but for long term 24/7 pc, i only set it at 4.3Ghz (kia si)
vcore 1.22 something, ideal 22-24c full load never exceed 50c

Added on April 27, 2012, 2:36 pm so you mean auto oc bring you up to 4.7ghz?

This post has been edited by rudolfjie: Apr 27 2012, 02:36 PM

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

What's your voltage?
