Overclocking E6300/E6400 W/ DS3 Mobo - By: OcNewb

WARNING-The results of this can damage your equipment, I nor THG are responsable for this. Use at own risk.

I have had many people ask me how to overclock this specific setup, it’s the setup im currently running now. I will walk you through this step by step.

First and foremost. Go download and flash to the newest bios found here

Part 2, you need to go out and download these programs:

CPUZ
SpeedFan
Prime95

Here is the system im am currently overclocking:

Intel Core 2 Duo E6400 w/Thermalright Ultra-120 HSF + AS5
Gigabyte GA-965-DS3
Evga 7600GT 580/750 + Kuformula VF1
Crucial 2GB DDR2 6400 Cas4 2.1v
P180B Case w/2 additional 120mm fans
SmartPower 500w PSU

Now that ive painted the system picture I migh as well show u a couple.









Ok enuff of that, now to the part you all want to read about.

After your bios has been flashed and your back into it:
First thing you want to do every time you go into your BIOS is hit CTRL + F1. This enables the advanced user features.

After every FSB increase Run the programs listed in part 2.

Open Advance BIOS Features:



Next open Integrated Peripherals:



Once those are all set open up MB Intelligent Tweaker (M.I.T.)memory settings are specific to your memory type, use the settings that is reccomended for your memory)




At this point you should have all the programs I listed above installed and ready to go.

Go here it explains exactly how to setup dual prime95 sessions. You want to run these for at least 30 mins to an hour. Once you have reached the point where you can OC anymore run it overnight to check for absolute stability.

Here are my results:

3.2-Idle pre prime95’s – 400fsb 1.3625v vCore:


3.2-Full Load after 30min Dual Prime95’s-1.3625 vCore:

3.3-Full Load after 30min Dual Prime95’s-1.4vcore:

Im still going and im up to 437, dual primes been running for 15mins. Will have updates soon

I love Giga-byte... What are you using for cooling... I cant see it well enough from the image, but that thing is HUGE... How do you keep it from ripping off a section of your motherboard

I vote sticky...

Great setup... dont like all thoose stickers on the front...

It’s the thermalright ultra 120 and it is heavy. The cool thing about it is that it can mount horizontally and vertically. I tried both ways, my temps dropped 4c the way it is. The stickers are more of a thing me and my buddies do. When we lan its kinda like the stickers on the side of a Nascar. Braggin rights =)

Hey,

I have a very similar setup, Temps hover around 50-55 with air temperature of 22 celcius, and 55-60 at 26 celcius.

You should run a super pi at 1M. I think it only utilizes one processor but gives you an idea of system speed. An FX 62 o/c with liquid nitrogen runs it in just under 10 seconds.

My setup runs the super pi 1M at 17.793 seconds!!! So technically with 2 processors you've got alot of computing power. I'd be curious to see what yours runs super pi 1M at. I stoped clocking mine higher but I'd like to see your results.

Up the MCH voltage by .1 it helps stability alot... and you can probably lower your vcore to 1.4375 at 3400 mhz... I've been running mine for weeks not a single crash!

here is my 1m, i forget how to get the decimal places. do you know how?

Great guide! Takes a lot of the mystery out of the process.

Some questions I have are about the features you've disabled, and why you've disabled them.

Why did you disable USB Keyboard and Mouse? Also, why disable the Execute Disabled bit and the Intel Virtualization? Doesn't make sense to me as neither of these involves throttling like Speedstep, so why disable them?

I guess I can get mine OC'ed and then turn them on and see if it wrecks shop.

Anyways thanks again!

Shouldn't you set the PCI-E to 100mhz and not auto?? Every guide I have read says to do that. I am just asking because I just tried my first OC with almost the same setup but I cannot get it past 2.88 ghz stable.

My rig:
DS3 rev 3.3
e6400
G.Skill 5-5-5-15 ddr 800 1.8v - 2.0v
Zalman 9500 HSF w/ ac ceramic
Corsair HX520 PSU
XFX 7600 GS GPU


I have tried just about everything I can think of. I cannot get it to post with a vcore of 1.45v and ddr2 @ 2.0v.
MCH +0.1v
FSB +0.1 v
PCI-E +0.1v

Right now I am running stable @ 2.8 (FSB 350 * 8) which means the RAM is running @ 700 (under specs).
It will post at an FSB of 373 but it crashes with prime95.

Any suggestions would be nice. I have read just about every OCing post in this forum.
