Hi guys, imma a newbee 2 OCing, and i can use some advice.

I have a P5KC with E6850 processor with pc8500 2 GB.

I have it stable now on 3.6, but i want 2 get it up 2 4.0.

Is that possible??

I have WC from thermaltake.

If I get it higher,like 3,8 if hangs after 1-2 hours, prolly my NB, coz I can bearly tough it than. Can U guys give me some advice?

Settings :

CPU ratio - 9.0

FSB strap North Bridge - 333

FSB Frequency - 399

PCIE Frequency - 100

DRAM Frequency - DDR2 799

DRAM Command Rate - Auto

DRAM timing Control - Auto

DRAM static read Control - Auto

DRAM dynamic write Control - Auto

Adjust CHA skew support - Auto

Adjust CHB skew support - Auto

Transaction Booster - Diasabled

relax level - 3

CPU voltage - 1.4250

CPU PPL Voltage - 1.50

FSB term Volt - 1.40

Dram Voltage - 2.00

Nort Bridge Volt - 1.55

Clock Over Charching - Auto

Load Line Calibration - Auto

CPU GTL Volt reference - Auto

NB GTL Volt reference - Auto

CPU Spread Spectrum - Auto

PCIE Spread Spectrum - Auto

Hope u guys can help me out,

What kind of temperatures do you have at the moment with 3.6 at max loads?

Download Orthos Stress Prime

http://sp2004.fre3.com/beta/beta2.htm

And also download CoreTemp

http://www.alcpu.com/CoreTemp/

Then download CPUZ

http://www.cpuid.com/cpuz.php

Run CPUZ to check your voltage, although it isn't the most reliable, it gives you a good idea as too how much Vdroop you're getting from in your BIOS in Windows. Orthos stresses your CPU to 100% for how ever long you let it run, when overclocking.. when you've found a speed you like, leave it running for around 1hr + (extreme but people leave it for 8hrs plus.. unneccessary!) Use CoreTemp to monitor your temperatures.

Report back with this please :)
 
Hi Dutchdude,

Ran it 4 5 min and already got a fail :

Using CPU #1

FATAL ERROR: Rounding was 0.5, expected less than 0.4

Hardware failure detected, consult stress.txt file.

Torture Test ran 5 minutes 50 seconds - 1 errors, 0 warnings.

Execution halted.

idle voltage was 1,384 Volts

max load was 1,328 Volts

max temp was 52 C

All this with the above settings

That is a big Vdroop!

Up your volts a bit more.. that is a volt error normally. Put it up to 1.45v and try again, see how well that goes ;)

got it running now 4 13 min now

vcore max load 1,3375(in Core temp) and 1,336(in CPU Z)

max temp 56

shall i wait longer, or go straight to 3,8 GHz??
 
Cool :) You can try 3.8GHz if you like.. I can't see it doing any harm though you might require a bit more voltage.

Try booting at 3.8GHz, and see what it does.. if it doesn't boot.. up the Vcore by one notch and try again.
 
already at 1.500 Volts on motherboard, but still fails in less than a minut

up Voltage even more??
 
Yeah, guess ur right

Been working on this over more than 2 weeks and always same result.

Above 3.6 it reboots.

Just 2 b curious, u think i just have bad CPU or bad MB?

Thanks anyway 4 ur time :-)
 
They just require a lot of voltage, you can try to boot up at 3.8 just to see if it will actually do it.. put your volts up to 1.55v to see if it happens.. if it does, cool.. turn it back down to 1.45 and 3.6GHz is the way forward.

For a single graphics card solution anything above 2.4GHz dual is enough and games SHOULDN'T be CPU limited, that is the conclusion we have come to on another forum.

Actually it does boot already at 1.5250 Volts, but that ain't the problem.

It crashes after 2 minutes with orthos and reboots.

Even with all the settings from FSB termination and NB voltage at max, it still crashes.Guess it didn't bought the right board 2 overclock.

And i don't use it 4 gaming, i just use it 2 re-encode movies, so stability is a must 4 me.

You need to up the volts more, as I said put it on to 1.55v and see if it's stable.. should be fine.. but do not recommend it for 24/7!

Keep it at 3.6, seriously ;)

Well, gonna give it a try again 2morrow, 4 2night imma gonna keep it on 3.6

Let U know how it works out later on. :crazy:
 
Well, i tuned it up 2 3.7 GHz and ran it 4 20 min. on Orthos.

Than it reached 70 Celcius and that it 4 me.

I don't want 2 get my CPU that hot, so indeed, i slowed it down again 2 3.6 GHz and gonna keep it on that.

Many thanks again 4 ur help, time and advice.
