OCing P5KC and E6850

[jaydee70]

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

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

Beginning a continuous self-test to check your computer.

Press Stop to end this test.

Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.

Test 4, 4000 Lucas-Lehmer iterations of M19174369 using 1024K FFT length.

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??

[°TheMadDutchDude°]

What temperatures are you getting..?

Also, what CPU Voltage do you have it set to in the BIOS now?

[jaydee70]

after 28 minutes its now 58 Celcius and I set my bios 2 1,450 like u said

[°TheMadDutchDude°]

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??

[°TheMadDutchDude°]

Nahh I wouldn't, 1.55v is the max safe recommended level. I'd stick to 3.6GHz and be happy with it.
