Need help for overclocking a E8400 E0

post #1 of 17
Thread Starter 
Hello guys, just wanna say that I haven't been into OC till now. However, I've been having an E8400 ( E0 rev ) for a while, and I recently purchased a Cooler Master Hyper 212 Plus cooler, to replace the box one the CPU uses. Still haven't switched them, as I would like to try overclock my CPU and see how it goes. My rig is:

MB: Asus P5Q Deluxe
CPU: C2D E8400 ( rev. E0 )
RAM: 2x2 GB Kingston HyperX @ 1100 Mhz 5-5-5-15
VGA: GeForce 9800GTX+
PSU: COOLER MASTER Silent Pro M600

I would really love a simple step-by-step guide on where to start with the overclock, and what are the exact settings I would have to tamper with inside the BIOS to begin cranking the CPU towards a stable 3.6-3.8 Ghz.

Would the cooler be sufficient to keep the CPU relatively cool?

Go and wisit the P5Q club from my signature link and you will find complete 4GHz OC settings for E8400 (445MHz FSB) and even my 500MHz FSB OC settings for E8400 (9x 500 = 4.5GHz or 8 x 500= 4GHz)..

CHEERS..

could you be a dear and post the settings in here, as the topic you pointed is like 143 pages long... I'm gonna have a hard time finding those settings.

Set your voltage to manual and leave it at stock.Raise your base clock until your at your desired level and test with prime 95 for stability.Add v core as needed.Basically that is it,you just need to keep your ram from overclocking to far.That alone should get you to 3.5 or better.

Try these 4.05GHz settings:

FSB freq = 450MHz
9x CPU multiplier
DRAM TIMINGS=5-5-5-15(rest on auto) or by memory spec
STRAP=AUTO
DRAM freq=900Mhz <<VERY IMPORTANT FOR STABILITY
DRAM STATIC READ CONTROL = DISABLED
DRAM READ TRAINING = DISABLED
OC charger=Enabled
AI booster=Enabled
Performance Level=10

Vcore=1.xxxV (what Chip needs to hit 4GHz,add a bit if you crash)
CPU GTL = 0.63x (on both settings)
PLL=1.54
FSB voltage=1.30V
DRAM voltage=2.0V
NBv=1.30V
SBv=1.2V
PCIE/SATA voltage=1.60V
NB GTL=AUTO

CPU & PCIE Spread spectrum=Disable
CPU & NB skew=AUTO
Load Line Calibration=ENABLED

All options in CPU Configuration set @ DISABLE and CPU MULTI @ 9x..

Testing methodology:

1. First test these with 6x multiplier and STOCK Vcore with Prime95 LARGE FFT for at least 6h to test FSB OC of the system..

2. If you pass reboot to BIOS upp your Vcore and set MULTI to 9x..

3. If it doesn't boot keep adding Vcore untill it does..

4. Then in Windows test 450MHz FSB x9 =4.05GHz with IBT 20runs w/ max RAM and if you crash then just upp Vcore and test it again..

5. If you pass P95 LARGE FFT 6h & IBT 20 runs then you're ROCK SOLID..

KEEP YOUR CORE TEMPS UNDER 75C IN ANY STRESS TEST..

Good Luck

CHEERS..

sweet, thanx a lot! I got a few questions though, KingT. You have specified:

DRAM freq=900Mhz <<VERY IMPORTANT FOR STABILITY

That's 900, not 800, right? Actually my current DRAM speed is 1066, not 1100 Mhz. I haven't tried overclocking it.

Regarding the Vcore, how much should I add up with a single step, if it fails?

And what exactly is IBT?

Apart from those, I think I pretty much got it. Will commence testing tomorrow when I install my new cooler.

Apart from those, I think I pretty much got it. Will commence testing tomorrow when I install my new cooler.

When you set FSB to 450MHz then set ram to 900MHz (450 x 2) as that is 1:1 ratio and the most stable..

For Vcore first Disable things like EIST,C1E,SpeedStep.TM function (everything in CPU configuration meni) and set CPU multiplier to 9x..

Then reboot to Windows and use CoreTemp program to check VID (your CPU's default voltage) and use that value as stock Vcore for your chip..

Upp Vcore by 0.02V untill it boots up at 4.05GHz (450 x 9)..

IBT is Intel Burn Test stability program..

Your cooler wil get the job done nicely,don't worry as I have rev.1 Hyper 212 and it keeps my Quad @ 3.9GHz at 70C in IBT and @ 63C in Prime95..

CHEERS..

Just OCed an E8400 E0 I found at work on a P5QC. Got 3.9GHz LinX stable (20 pass, max memory) without too much effort. I happen to have BIOS screenies on my phone so here's the goods for ya.
Code:
FSB Frequency: 434
PCIE Frequency: 100

CPU Voltage: 1.37500
CPU GTL Reference: 0.63x
CPU PLL Voltage: 1.56
FSB Term Voltage: 1.30
DRAM Voltage: 1.50
NB Voltage: 1.40
SB Voltage: Auto
Load Line Calibration: Disabled
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
CPU Margin Enhancement: Performance Mode

SpeedStep/C1E disabled in BIOS.
At long last...
