Guide: How to Overclock your E8400

So I am writing this guide because I read lot of Overclocking guides and none of them helped, I decided to write this in hopes of it helping others like me. This overclock is very easy and safe to do. However my guide may not work for everyone as it depends on your Bios/Motherboard.

What You Need:

Aftermarket Cooler- I reccommend either a Zalman 9500 or Thermalright Ultra 120
Thermal Paste- I'd go with Arctic Silver 5
A Case with Good Airflow
These instrutions printed out

Now here is a very easy overclock we are going to take your E8400 to 3.6GHZ without any trouble.

Shutdown and Unplug everything from the back of the case, take the side panel off.

Remove the retail cooler and paste, apply a small amount of the new thermal paste to your CPU and connect the Aftermarket Cooler.

Now close the case and reconnect the cables, reboot your computer and gointo the Bios settings.

** Don't see your Mobo listed below or want to submit you own overclock settings, just postem and I will give credit/add to the OP.

With Gigabyte Board:

We are looking for the CPU FSB Frequency, PCI Xpress Bus Frequency, and Memory Multiplier Settings.

Now set your CPU FSB Frequency to 400mhz
Now set your PCI Xpress Frequency to 100mhz
Now set your Memory Multiplier to 2X (Assuming you have DDR2-800 which most do)

With Asus P5N-D Board:

You want to go into Jumper free Free Config
Set your AI Tuning To Manual
Set your PCI-E Bus Frequency to 100Mhz
Goto Voltage Control
Set your VCore to 1.3125
Set your NB to 1.32
Set your HT to 1.32
Goto FSB and Memory Config
Set it to Unlinked
Set Your FSB to 1600
Set Your Memory to 800 (Assuming DDR2-800)

Congratz you just now have overclockered your E8400 and it runs very stable and underload it should be at 37c-40c.

You can do this with Heatsink and fan that came with the processor. but it will be around 50-55c underload which I do not recommend. The Aftermarket Cooler and Paste is $60 together at the most.

Hi, i have a quick question

how can i under-clock a ddr2 1066 ram to fit the 2x memory multiplier and the FSB

for example i want to overclock an E8400/E8500 to 4ghz, that would be a 444 FSB multiplied by 9

but the ram im going to use is a Kingston HyperX 5-5-5-15 2.2V and i don't know much about ram and its latencies

is it safe to overclock exceeding 4ghz maybe 4.3ghz o 4.250ghz?

I'd gladly accept any constructive comments and help :)

Yes you can underclock ram, to help get the 1:1 ratio, you can also loosen the timings. For 4GHZ you would use 445mhz and increase the voltage. At 4GHZ you will be at 60c underload.

It really depends on your Motherboard and oother hardware. Just keep tweaking the settings till you get a stable run. Gigabyte Mobos make the best overclockers. Just don't get the cheap DS3L/R/etc. ones, get a $140+ one.

The highest stable overclock of a E8400 that I have seen is 5724Mhz.

pERSONALY I WOULD USE a overclocking tool, since just going into BIOS can cuase problems ect. and overclock can soemtimes not work properly or lose it.

I hopeing to overclock my e8400 to around 4.0 ish, though i will use a overclocking tool,

main issue i would advise is::DO NOT OVERCLOCK UNLESS YOU HAVE A VERY VERY GOOD AIR FLOW OR WATERCOOLED SYSTEM.

basicaly dont get greedy with ocing, since it makes stress on the hardware of your pc, and can make the life of your hardware MUCH lower.

overclocking is NEVER 100% safe i think you should add, since things DO, and WILL go wrong some time during a overclock or with parts. though it depends how wrong things go and how badly that count.

example... pc may get louder...on other hand pc may overheat and fry chip... it depends. read lots of guides and vids.

to be truthful....no body will post in your thread because its old and not stiky.

try asking a MOD to make you thread stiky.....thats all i've to say

Do not, I repeat, do not overclock woth some "tool". Unless you have a locked BIOS, the BIOS is the way to overclock. Programs just cause instability and problems. If you mess up the setting in the BIOS all you do is clear the CMOS, and you are good to go.

And all of these "guides" are worthless. For one no one here checks the guides before they post on their own. And understandably so, I would not take this guy's advise, no offence, but you don't really sound experienced enough to be writing a "guide". Also with how quick tech moves this will be obsolete in no time.

You understand every motherboard is different, and that every BIOS is different right? Giving someone a "guide" using your board does not mean it will be the same for them.

gla300

well, its not a sticky yet, cuz its not finished yet, ive still got to end the benchmarks section, but then, nutDAVE3 will sticky it :)

I have my E8400 running at 3.6GHz without the use of a aftermarket cooler...

It runs quiet well...at around 48C under load.

You can get around 3.6. But not 4.6 with stock cooler.

I know every mobo is different, and yeah im not as experenced at overclocking as some, but I know how to OC and remain stable. Im just tired of clicking links to overclocking guides and getting nowhere with it. I though I would try my hand at writing my own guide to see if it helped others.

People can feel free to submit what they did with there mobo to OC and I can add it to this guide, which would inturn help more people.

This thread...is old.
