guys ..i;m noob in overclocking.. after done lots of reading on guides to overclock..i;m still doubt or probably scared to do it myself..
Can u guys help me by recommend the settings such as FSB,CPU & Ram voltage/ratio, before i decide to overclock..

I decide to overclock my current Q6660 2.4 ghz to 3.0 Ghz.. i don't plan to overclock more than 3.2 ghz btw.

Is it okay for me to use my current CPU Stock cooling while i overclock these settings.




Here;s my spec.


Chipset :Q6600 2.4ghz,
RAM :2x Kingston HyperX 800 NVD
Graphic Card :MSI 9800GTX (Non - Overclock)
Motherboard :MSI MS7512 Platinum(CF)
PSU :Cooler master-Real Power 700 wat
OS : Window XP SP2
Bios : 1.3 version

Pls help..thanx.. Your recommendation is very much appreciated.

Try ask ur quest here http://forum.lowyat.net/topic/493588

Yup going to 3Ghz should be absolutely no problem for your board. Don't be afraid, modern Intel processors are pretty hard to kill. Do this:

FSB: 333
Multiplier: 9
Vcore: leave stock first
Vnb: leave stock
Vdimm: leave stock
RAM divider: 1-1

Stress test with IBT 20 runs, if pass, you have a stable system. If not, up Vcore one notch until stable. (Shouldn't take many notches). After it's stable, you can up RAM divider to 4:5 and Vdimm +0.1. Stress test again.

hey Zerohour..Glad to hear from u finally giving advice...

i tried as wat u said..works man .. I tested it with WPrime..so far the test wif Stability TEST..no problem hehe..

i even tried playing on Crysis Warhead..no problem or hanging watsover..


Fuh~~~~ So wats next ?

Should i set the ram to 5 - 5- 5- 15? and DRam volt to 2.0? RAM DIVIDER?

Looking forward for your reply..

Err what's the RAM timing now? 5-5-5-15 is conservative, but RAM tweaks should be done last. Pump FSB to your target first.

Anyways, your target is 3.2Ghz right? Target FSB then = 356Mhz.

Section A: ~3.1Ghz
1. Go to FSB 345, leave all voltage settings for the moment.
2. Use IBT (Intel Burn Test, it's faster and more accurate) 10 runs.
3a. If pass, good, go to section B.
3b. If fail, bump Vcore one notch, retest.
4a. If pass, go to section B.
4b. If fail, bump Vtt and Vnb one notch, then retest.
5. If pass, go to section B. If anytime fail, repeat steps 3 and 4 (bumping Vcore and Vtt/Vnb 1 notch at a time) until stable.
6. Take into account temperatures. You're on stock cooling, so it might get out of control. If load >70C, stop increasing FSB, that's your max without an improved cooler.

Section B: FSB356
1. Once you have a stable system from Section A, reaccess your BIOS and pump FSB to 356 = 3.2Ghz.
2. Run IBT 10 loops, if pass, Section C.
3. If fail, as above increase Vcore and Vtt/Vnb until stable. Shouldn't take much, but be careful of temps.

Section C: RAM - DDR2-890
1. Once your system is stable at 3.2Ghz, it's time to play with the RAM. FSB356 will give you DDR2-702. If you want more performance, bump Vdimm to 2.0 like you said and set memory divider 4:5.
2. This will result in DDR2-890, which your RAM should be ok with. Run memtest: http://www.memtest86.com/
3. If pass, good, now set timings 5-5-5-12 and run memtest again.
4. If fail, sorry your RAM cannot take it. Back to 1:1, set timings 5-5-512 and run memtest.

At the end, you'll hopefully have a stable 3.2Ghz system =)

Good morning !! thanks for ur great effort and time man..

but as u can see... i jus want a decent 3.0 ghz .if u read my first post..lol..nvm...really appreciate ur advise..


fyi..my max load (during Wprime test) is already 70c (realtemp) on the first 2 core.

for more information.. CPUID shows my CPU voltage is at >1.39v.

So i thought i should jus stick to 3.0ghz (until i get a good third party cooler to max it out like 3.2ghz ).. At the moment i tested on crysis warhead for 30 minutes and my CPU temps shows only max 60c although for some ppl..it still consider hot..

To cut it short, Since i'm stable at FSB 333mhz @ 3.0ghz ..Do i need to tweak my ram stuff ? ( i will test on IBT* Memtest later after work)..
after that i'm good and happy already..

And onemore thing, should i adjust the PCI to 100Mhz?


Kindly please advise..Thanks.......

Seem like you are the one and only with this kind of patience

yea..i agree.. u dun get to see this reply very often. Mostly,they just throw a link to u you & figure out...if i were him,, i probably ignore the post..


credits to Zerohours.. really helpful person..

Good person eh this ZeroHours? His avatar used to be very3 goodd...U understand?

You're welcome. If I have the time I sure will try to help one =p

Okie, then 3Ghz is a fine target. Temps and voltages look good too.
At 333Mhz your RAM will only run at 666Mhz, which is kinda a waste la cos you have DDR2-800. Performing the RAM tweak like I said earlier will prolly increase performance another few percentage points.
It'll be even easier at 333Mhz as opposed to 356Mhz cos at 4/5 your RAM is only running at DDR2-832, which your RAM should definitely be ok doing.

I'd go Vdimm 1.9, 5-5-5-12, divider 4/5 and run the memtest.

And yup, set PCI-E to 100Mhz.

Neo - you like my old avatar issit? Haha I got bored la..maybe in a couple days or so I change back =)

well going for extra 0.2ghz wont hurt..haha.. Seems like someone going to start getting greedy..


I give it a try on overclocking 3.2ghz..let u know later.. now in office..haiz..want to get back home now,,

Haha I'm about to leave office, but sure havoc la. Rain+Friday+Ramadan means super traffic jam. I'm 50-50 between going shopping and trying to make it home..

As for the overclocking, sure let me know la =p

so far so good.with 3.1 ghz..with intel burn test ..i din mess up the CPU voltage yet

..over 80-89 c..tats hot during burning test..should i go further to 3.2ghz?

Nah I reckon you stop then. 80-89C under IBT (it generates a lot of heat) translates to 65-74C under normal usage, which is kinda hot, but tolerable. Time to tweak RAM =p

so wat timing/ratio/volt for my ram should be on 3.1 ghz..?

Same as above: Vdimm 1.9, 5-5-5-12, divider 4/5. Write down your current OC settings first in case it doesn't boot and you have to clear CMOS.

4/5 ?
means 1: 1 :2 ?

i dun have 4/5 in tat option area..

and btw,, my PCI frequency options shows this option only : 37.3 and 42 ..


cant set to 100mhz

This post has been edited by Jimsee: Sep 26 2008, 07:25 PM

Nono. PCI to 33Mhz, PCI-E to 100Mhz. Those are the reference speeds.
Ok, if no 4/5 get as close to 800Mhz as you can using the dividers that are available.

w000w

u mean CPU-Z show ur CPU voltage at 1.39? it cant be so high,wif 1.39 V, i can do 3.4ghz i think. ur CPU vcore set auto in motherboard BIOS is it??for mine,if 3.0ghz, i set at 1.2625V, 3.2Ghz at 1.31V at bios.

if u're using stock cooler, suggest u change it. most ppl wif Q6600 dont use stock cooler as the proc is so hot.oh yea, if u're doing 3.2Ghz, suggest u do 400X8 set up instead of 354X9.reason is,wif 400X8 setup, u get 1600FSB. for quads,its actually 2 core2duo fitted in a package call core2quad. these 2 core2duo proc communicate wif each other through ur FSB. so i think higher FSB does benefit the quad more. and 400 FSB dun need to bump NB and VTT voltage yet.i'm using the 400X8 setup and its stable for 50 rounds of IBT.

aaaii if zerohour is like his avatar ..... most helpful....bump

Haha I'm a guy la! =p

ic..
yea..currently i din mess wif the CPUvoltage on 3.0ghz .. my idle temp is 47-53c..

well, i try lower down the volt as wat u said... thanks..


and regarding the 400x8 setup..i give it a try someother time

wat thirdparty coolers u guyz would recommed..something affordable and good..

This post has been edited by Jimsee: Sep 30 2008, 11:07 AM

Err, affordable is a bit subjective. How much exactly? I'd recommend the Core Contact Freezer for RM160-RM180, and the Arctic Freezer 7 Pro for around RM120.

recommend Xigmatek S1283 non red scorpion type RM150 at imbi.if u hv enuf money,dun buy artic freezer 7 pro.i've 3 coolers now. xigmatek HDT-S963, HDT-S1283 and Artic Freezer 7 Pro.performance wise, the artic comes the last. zer0hour's suggestion on sunbeam core contact freezer is the king now followed by S-1283. i dun like the mounting mechanism for core contact freezer only.prefer screw kits wif S-1283. or if ur mobo no space for both coolers, go get deepcool killer whale.there is a review around dis forum. go search.
