pro is the one with the fan control knob, Bl stands for blue light which glows blue, pro also got blue light

Copper is good in absorbing heat while aluminium is good in releasing heat. Go and figure why they use that combination.

copper contact base + alluminium heat sink

to me good HS design must got copper core touching the processor covered wif aluminium...

Hows your DS-4? seems like u alrdy satisfy with current clock speed.. dont wanna try higher??

This is my first time to overclock a cpu since i just got my new computer. All my previous computer were dell that doesnt allow me to oc anything. Anyway, i was following the guide from this website. I hope that's ok, and there's a few things i don't really understand.

My computer specs are gigabyte ds3, e6400, 2gb corsair xms2 ddr2 800, epsilon silent 600w and xfx 8800gts.

Yes, i did update my bios to the latest.

My Problems:
Part1. Tidying Up Your BIOS

I can't seem to find it in my bios.

What's that?

Not sure which 1 issit.

I can't seem to find it.

Part2. Memory Adjustments

My timings is 4-4-4-12 with 2.1v. I cant seem to find vDIMM


Part3. Voltage

The closest thing i could find was ddr2 overvoltage control and the max for it is 0.7v

I couldnt find vMCH but i could find gMCH, and the max for it was 0.3v.

The max for it is 0.3v only...

I langsung cannot find this.

Any help you guys could give me would really be appriciated alot. Thx alot in advance.

i get lower performance wif higher clock... seems like my GC bottlenecking... wait until i get Radeon X2300 series 1st...

I too have the same mobo and proc as you, and i just OC it yesterday.
refer to the same website as yours and also HERE.

OMG.... Thx alot dude, that site really helped ALOT... Anyway, now running some test.. CPU temperature now 74C at full load. Ill post more questions as soon as i find any errors. Thx alot again dude.

Ok.. Sry to post again, but i just want to make sure im doing everything the correct way. This is my hardware specs first.
PSU: Epsilon Silent 600w
RAM: 2GB Corsair DDR2 XMS2, 5-5-5-12 (i think)
MOBO: Gigabyte DS3
CPU: Core 2 Duo E6400

Ok, this is exactly the steps i did:
1. -Entered the bios.
2. - Disable CPUID Max to 3
- Disable No-Execute Memory Protection
- Disable C1E
- Disable TM2
- Disable EIST
- Disable Virtualization Technology
3. -Disable Smart Fan Control Method
4. - CPU Clock Ratio (CPU Multiplier) at 8x
- CPU Host Frequency (FSB) at 333MHz
- PCI Express Frequency at 100MHz
- Disable CIA2
- System Memory Multiplier at 2.00 (1:1 Ratio)
- DRAM Timing at 5-5-5-12
- *** DDR2 OverVoltage Control +0.2V (2.0V) ***
- FSB OverVoltage +0.2V (1.4V)
- (G)MCH Voltage +0.1V (1.55V)
- *** CPU Voltage at 1.375V ***
5. - Fired up CPU-Z
- Using G15 Keyboard to monitor the temperature
- Fired up SpeedFan to monitor the voltages
- Ran dual Prime95
- Used the ctrl+alt+delete to for the CPU Usage

Could anyone plz tell me did i do anything wrong. Cause im still running it for testing.

your setting seem good enough. Here some tweak on yr current setting:
1) Put FSB OverVoltage = Normal
2) Put (G)MCH Voltage = Normal
These 2 setting should put normal first coz it tend to heat up yr North Bridge and Southbridge. If yr current setting is stable under dual prime95...then is better to set to default value.

Here my suggestion on testing for stability:
1) Alway use Intel Thermal Analysis Tool (TAT) to measure/monitor temperature. Download from here : http://www.techpowerup.com/downloads/392/mirrors.php
2) Use Orthos to test stability ( alway use small FFTs to test CPU). U can get from: http://sp2004.fre3.com/beta/beta2.htm
3) If U using Stock cooler, is better not to OC too high...Alway control yr full load temperature below 70C

Happy OC..

Thx alot dude. Ya, im using the stock cooler fan, but im also using the Aurora 3D which comes with the 2 huge fans. Anyway, im not sure what timing i should use, my cpuz showed this timings.
[attachmentid=167095]
Im not sure which i should be using.

Ohh, and which settings do i change to lower down my temperature.
And should i run 1 or 2 Orthos?

Thx alot dude.

U cannot do much to lower down yr temp with stock cooler....unless U dont OC.. . U can undervolt but I wont go into that much further since U new in OC...

For ram timing, yr current setting is ok....dun touch on ram timing first..do steps by steps...CPU OC then ram timing..

Runing 1 orthos is enough coz it was designed for dual core proc.

Hmm.. Ohh well, anyway.. when im using the Intel Thermal Analysis Tool (TAT), it shows the temperature at 77C, but at the same time im using SpeedFan and it's showing 71C, both while using orthos of course... Which is it lol. Anyway, should i leave it as it is at 77C with full load?

Btw, my hands are feeling itchy to go for 375fsb, would it be ok?

Alway trust TAT on dual core temp. Errr...77C load is consider high... I dun mind U try 375FSB....but....anything wrong happen dun blame me...

fixing the stock cooler is a headache, always no contact, high temperatures,
1. check your cooler contact
2. undervoltage!!! say no to overvoltage, E6300 can run 400x7 at 1.225v

hey all...just finish assembling cd now...still runnig at stock speed.
idea on how to oc...anyway im using a ga965p-ds3 with a 1gb corsair value ram at 667mhz....just one to knoe anyone using same set up like me...oh yea it runni on stock fan..


proc:conroe e6600@2.4g stock speed,stock coolin
mobo:ga-965p-ds3 rev c2
memory:corsair value select ddr2 667mhz 1GB
vga:gecube ati radeon x1600 512mbddr2
power:cikai brand 450wt


hmmm still figurin out on how the hell to overclock....im a nooooob.

overclocking e6600 with a cikai brand PSU.. will be very risky. Do read up the stickies concerning overclocking, paying particular attention on the importance of the PSU.

My recommendation - dont overclock. upgrade you PSU first. If you really want to, make sure you've read and are aware of the risks.

that wat i tought oso...since my next investment either it a another ram or a good psu...hmmm

ram value good enough for mild oc,

psu get cm real power or enermax FMAII

ok then goin out to digital mall seksyen 14...i hope all it there got good power suplly...thanks fer the tips

ok just come back i bought myself a power logic 600pt for rm220...goin to fix it n try to oc...

Get PSu 1st b4 get anything else. RAM wont affect overall perf too much.

Edit:


I believe tht is not the Best choice... try top up a bit get CM REAL Power if budget tight. Recommend Enermax FMA.

yeah?coz im a damn noob when it come to buying power suplly...too bad i bought it edi...haih...

Nvm.. dont o'c your pc 1st. Power Logic PSU is almost same with the brandless one. Not too stable becos rails not solid. I think 12V rails is less than 18A.
Can try change with the shop.. get CM Real Power by top up some money.

Dont worry about o'c things.. for normal use u wont feel the difference.

haiya... wat this forum is for ler...?

yea but no worries....actually i got very good deal when i buy this upgrade kit actually...i bought this conroe 6600 rm 1160,ram cost me rm 360 then mobo supposedly cost me rm 530 but then when i wanna pay it that time the cashier some how forgot to key in my mother board price so it end up for me to pay for only ram and proc only got free mobo that price rm 530 ...that why i go get new power supply...but to bad i guess mobo is not in the warranty la coz at the receipt no mobo...have to contact suplier of gigabyte i think in order to rma if anythin happen...

Which store you buy from, i wanna go lol. Anyway, i got a question.. When i use orthos small test, my "default" e6400 is already reaching 77C lol.. i havent change the fsb yet. So my point is, what if i raise it to 300 fsb and it's still be running at 77C?

that seem kinda hot for your proc to operate like that...77??hmmm..u might need to re apply the thermal paste n refox the stock fan nicely.

I think you installation of the stock fan and heatsink is not done properly.
Check properly whether there a gap between the heatsink and your CPU.
maybe that's why it is hot.

I now OC my E6400 to fsb=380 and the temp is about 58C using zalman 9700.

I think my problem is that i havent modify anything yet. I havent add any thermal paste or anything.. I just installed the processor, but is it suppose to be that hot using the stock fan?

it is not suppose to be THAT hot lar. Something wrong with your installation of stock fan and heatsink.

Bah.. So i should take it out and put it back in? Ok, it's gonna be my first time im removing it, anyone got a step by step pic guide for it? thx alot.

Another question, both everest and speedfan shows that my cpu temperature is 41C but as for the Intel Thermal Analysis Tool, it shows 56C.. Thats alot of difference in temperature.. =.="

What temperature u got using CoreTemp program?

Use TAT.. i think more accurate.

guys.. stupid question here..

How do i remove the northbridge heatsink? Want to apply AS5 on it but dont know how to unmount it. THanks.

Just open and take off the pin.. then move the HS a bit and a bit slowly.
Its easier than the south bridge. Dont need use screw drive if not tight.

open what? the little white things beside the northbridge hsf? Or just pull it out?

btw, my northbridge HSF quite hot la.. only oc to 400fsb, summore fsb and mch voltage all at default level..

Push the white pin..
i think u need take the mobo out from ATx case. Becoz u need release the pin at the back side of mobo. And u need to reapply the As5 later so better take mobo out 1st.

to unmount the northbridge hsf need to take mobo out? grrr.. leceh la ini macammm..

how do i monitor the northbridge temperature? is it in the system temprature under easytunes5? or should i use some other software.. everest or something else maybe?

Take the mobo out should be easy.. just a few screw, wht so difficult? lol
I think System temperature = NB temp maybe.

U mean yr CG bottlenect the proc's clock speed??

hhmm.. system is the NB temp? 40c hot or not?

hey do any of you got my kind of problem?im using ds3 bored but then my problem is it is freakin slow for me to acces stuff in my dvd rom n sumtime happen wen to open ide hard drive worse than my p4....my win xp program is install in ide hard drive not sata...so is that the reason?should i let all my ide ocupied with dvd drive only no hard drive?how your set up?sata?hmm somemore my cpu usage only 5% n memory still a lot...where did i do wrong?

is this question relevant to Overclocking? I think not. From yr post, I noticed u already know the answer. Just make a partition on yr SATA HDD and ghost yr OS from PATA HDD to SATA HDD. Make yr SATA primary. U can still continue connect DVD drive together with PATA HDD act as non-OS drive....

Next time, do post it on the correct section....TQ

Me also never hear about this... only hear proc bottlenect gc performance...

I believe there is only CPU bottleneck GC, no GC bottleneck CPU performances.....

no clock... performance ler...
i can get:

358x7(2.506GHz), RAM 895
Fear test
0% below 20fps, 70% below 45fps 30% above 45fps

430x7(3.01GHz), RAM 1075...
Fear test
0% below 20fps, 78% below 45fps, 22% above 45fps

457x7(3.199GHz), RAM 915...
Fear test
3% below 20fps, 65% below 45fps, 22% above 45fps

All at auto voltage settings... I guess my GC can't catch up...
If u are me which 1 will u choose ler...?

damn... lousy management...
i would turn tat IDE drive to external if i were u... and try and see if u can RAID ur SATA... nvr tried tat b4...

BTW... any1 here saw the contest in Gigabyte website...?
