post #1 of 9
Thread Starter 
I got a new e8400 with a zalman 9700CNPS heatsink. I got the fan on full tilt and can some one give me like the specs to get it 3.6 GHz stable? like voltages, Stepping etc. BTW, MOBO is DFI LANparty intelx48 chipset.

First you need to figure out what the multiplier is in the BIOS options, then just multiply your multiplier (WOW!) by your FSB to get the desired speed: if your multi was 10, you would do 360FSB X 10multi = 3.6GHz. Then, you're going to want to find the option labeled "CPU VID ADD" and go to the second option, should be "+25mV". Boot up and run Orthos for a few hours, and if you shut down, move up to the next option in voltages. Good luck!

vcore 1.275 (lower it if stable)
multi x9
fsb 400
post #4 of 9
vcore 1.3V
multi x9
fsb 400

Go with fsb of 400 and multi x9 and tweak the voltage. Some procs need more juice to hit a certain mark. Start around kpo6969 and my settings and you should be good.

update:made new thread hehe

Hi i am new to overclocking but I wanna give it a try with my setup.

- I just built my new rig and here are my specs

Antec P182 Case
Intel Core 2 Duo Wolfdale E8400 @3.0GHz (9x333)
Tagan BZ Series 700W
Asus P5K Pro P35 chipset
Inno3d GeForce 9800GTX oc.
OCZ Platinium 800mhz 4GB 4-5-4-15 @400mhz
Seagate Barracuda 500GB
Windows Vista Ultimate 64 bit

CPU cooling:
Thermalright Ultimate Extreme 120 with Sharkoon 120mm @1800
Thermalpaste used: Mx2 from Arctic Cooling

My problem starts with my idle temps

CoreTemp Beta v 0.99,EverestUltimate 4.5 and HardwareMonitor 1.10.0 -
All show temp around 49 - 50°c

but with

RealTemp 2.60 it stays around 38-40°c.

I had planned to overclock my E8400 to atleast 3.6ghz - what everyone seems to do easily but with these idle temps i'm afraid to do any overclock.

ps. i have tried mounting the HS atleast 3 times and always get same readings from temp...

I'm running out of ideas and losing all hope.

Can anyone tell me what i could do to maybe lower my temps.

Got mine running very nicely at 3.6GHz, had some problems though, like random crashing in the middle of games. Done it once during GRID, and once during EVE Online. My voltage is only at 1.225V, might up it to 1.275V and see how it goes.

A couple things. First of all RealTemp gives the accurate readings with that E8400. Are your ambient temps high? Like 80F?

When you apply the thermal compound you need to put a thin even layer right down the middle. Too much TIM and it actually acts as an insulator.
Here's an article on correct application of the TIM. http://www.arcticsilver.com/pdf/appi..._dual_wcap.pdf

And if that doesn't help. The last straw would be to lap your CPU cooler. And to lap your CPU. That will definitely bring down temps.

The E8400s are known to give inaccurate readings. Don't be affraid to OC the crap out of it!
