I'll give it a look up but my issue is not that the q6600 needs high voltage but whether my particular mobo has issues since it's reported that the Asus P5K series has significant droop issues. Before the pencil mod I simply could not push up to 3.0ghz

Thanks and i'll get back to you once I get home.

Did you see this as an issue in achieving stable overclocks?

kmarc, almost 0.08V quite a lot, no wander why u need to set till 1.4v for 3.2G

i guess u need to do some pencil mod on ur gaygaybte lol........ hehe

Q6600 already good enough ady la....
still need to overclock meh!

Good news I reapplied thermal paste. After 20 minutes on priming temperatures is at 52-56 C. Is that more in the correct range?

I'll try retesting stability again on a higher overclock.

My new P5E vdroop is scary. BIOS set 1.435, full load 1.36v. Used to be stable @ 3.5Ghz with 1.36 load. Now can't even boot @ 3.5Ghz. Running only @ 3.2Ghz now. Seriously need some pencil modding done.

Hi guys, I've had a Q6600 for quite some time now and today I just did my first overclock (OC noob  ) and OCed my Q6600 to 3GHz for starters. Everything seemed to be fine and all and went into windows. And then I started up Prime95 to stress test. What I got was the first time I stressed test it after just 4 mins there is an error in one of the Cores. But I restarted Prime 95 then after 1 hour only an error showed up. Restarted again then this time it took 4 hours ++ for an error to show up. I restarted my PC and this time 4 hours and still no error. Is this normal ? and does this mean my system can be considered "stable" ? Oh yea btw my rig specs is as shown in my sig. Temperature on full load with no air conditioning at all on a very hot day after 4 hours highest for Core 1 66 degrees, Core 2 66 degrees, Core 3 62 degrees and Core 4 also 62 degrees. 

my Q6600 OC.. thanks to Kmarc's guide to OCing Q6600..

OC to 3.2GHz (400x8), 1.38v...    stable with temp from 60~67'c  ... cooling with Tt Silent Tower with dual 80mm fans..
had problems OCing to 3.5Ghz... wasn't sure wat voltage to use...  but so far so good... ran Prime95 twice on this temp...

if anyone can give me some suggestion on how to OC further, please do tell.. thanks 

not sure if it's vdroop or vdrop... hehehe... still new with these lingo... hehehe..

at 3.2GHz, temps are just nice... idle is around 32~35'c and at load is around 55~57'c

vcore i set to 1.4v la... but in cpuz is 1.242v during load.. the xigmatek is really damn good... hahaha.. changed the fan to Nidec Beta V.. so, highly recomend it.. if with stock fan, load temp is around 56~59'c la... it's good also...

At last managed to get it to run at 3.7ghz 

what is push + pull config? =.="

When i enter Bios it says that the stock core for my q6600 is 1.325. Is this normal or does it indicate a weaker processor. I can't hit even 3.0 wif a core of 1.216.

Yeah, and i don't think i can hit 3.2 with my current setup as at 9X330 im getting a max temp of 72 when i stress with p95. Stable but i think if i want to hit 3.2 i may need to change my zalman CNP9700 NT. Kmarc may i ask for your load temps at 3.2 Ghz?

allur.....my rig as stated below....

can somebody plez teach me how can i o/c my q6600 untill 3.2GHz....
since i'm using CM V8.....
coz it's a waste if i just use it at 2.4GHz....

plus i dunnot use Easy Tune6..... (GA-EP45-UD3R)
i want 2 use MIT ( Motherboard Intelligent Tweaker ) only...so where should i begin?
plez help me aaa

hmm...yesterday night im trying to set my q6600 to  425X8 to make it 3.4ghz  by vcore 1.375

but when it reach vista load screen, blue screen came out

is it need to add more vcore on it or the FSB for my proc alr?
current setup 400X8  vcore 1.34

Hi all. I got some question for ask.

Yesterday i buy 2x 2GB Corsair Ram (CGM2X2G800) plan to play more about overclock =X sorry i tight of budget so buy this value ram

Okie here the problem i face.
My Q6600 VID is 1.2875
previously I can get 3Ghz at Vcore 1.29375 stable in prime95 (15minits only:P)

Today, A rainning day. I try to hit 3.15Ghz with Vore 1.300. I see something blue page came out few second and pc turn off @@. is this what you guys call BSOD? is so, I first time see this thing. Ha Ha.

So i guess Vcore no enough. add to 1.35... result= fail. pc restart when load window logo. Nvm.. try add to 1.38. The pc went to black screen while going to window logo. no sound. wait 3 minits still no response. 

At the end i give up. set back to 3Ghz. no problem so far =="

Q: Why cannot start? is it Vcore ?

Q2: If yes, why 2.4 to 3.0 only need increase so little while 3.15 need so much? Big jump @@

15minits no enough i know. Don care, CPU no always full load =X no shut down ok ler

by the way about ram and northbridge... I never touch that before 

Need take time refer your guide again. Hehe all learn from you leh.

Thanks you kmarc

Edit: Hi kmarc, I doing overclock by following your guide. the RAM multiplier is set to 2. do you mean downclock RAM is this? By the way what is northbridge =X

Edit 2: Hi kmarc, So far i tested 3Ghz with prima95 over 2hours still no error (still running.. but going turn off sleep soon ) quite happy with it. But before this I try hit 3.06Ghz with vcore 1.32. BSOD and shut down again ==" it seems like need alot vcore after over 3Ghz.. or something have blocked me to over 3Ghz?

Hi kmarc, thanks to you again. after reading your guide, I finally can boots into windows after increase Northbridge by +0.2v @@"
New knowledge learned.

3.08Ghz with vcore 1.35 run prima95 25minits so far no problem now.
The Northbridge i set to +0.1v . full load temp is 60'c 

can anyone advise izzit my rig is ok or not? my idle 3.4ghz @ 1.44 is around 38'c and full load at around 60'c, VID is 1.325v. i use this setting daily and 4 my gaming. it's passed prime95 stress tested, izzit ok?

Added on May 4, 2009, 11:19 amedit...... actually the full load temperature is 54'c ~ 58'c.

Hi kmarc, Currently now test 3.13Ghz with vcore 1.35 still no error with prima95 in 10minits (still running). Hope it stable 

Anyway about power option at control panel. I set my power options to power saver mode. The processor power management state is Max 50% Min 5%. It quite alot difference compare with balanced mode which is power management state is 100%.
The CPU temp drop around 10'c in saver mode compare with balance mode. And I didn't found any trouble yet. Is there safe?    it look nice 

Kmarc can i take my rig to ur place you help me get my Q6600 to 3.6 ma? 

Lol i learn how to push mhz and vcore from your guides oso one ler 
I'm just hoping that my new true 120 will perform a lot better then my Zalman 9700. 

hi pl4tinum, long time no see u post ler.

Where you going get ur true 120? So far i know that True black 120 selling RM300plus at kuching    that look cool 
Hope to see your result soon.

Edit : WTH today... when i test for stable today. It direct BSOD and shut down... Even i try to downclock to 3.10Ghz.   Computer bad mood liao.

Er.. guys 8x375=3Ghz and 9x333=3Ghz the Vcore can remand same between this 2 right? 8x375 better?
