Beginner OC'r Needs help - Page 2

I've read couple of guides for overclocking... but now I need some help.

I got a asus P5K motherboard with an intel E6600 C2D processor @2.4Ghz, ddr2-800mHz

My FSB frequency is 350
Multiplier: 9.0
ram = 1:1

Current OC:
Frequency = 3.15Ghz
Ram = 701Mhz


Im not sure about the timings of my ram, was doubting about some settings:
Cas# latancy = 5dram clocks
Ras# to cas# delay = 5dram clocks
Ras# pre time = 5dram clocks
Ras# act time = 15 dram clocks
Ras# to Ras# delay = 10
REF cycle time = auto (36)
Write recovery time = 6
Write to read delay = 10
Read to pre time = 10

I have not touched the voltage settings, but cpu voltage is set on auto but I don't know the given voltage of it.

I have a zalman cpu cooler,
I'd liked to know if the ram settings are good, or can be better, and how I can overclock with the voltages.

Try this.

Ai Overclocking to manual
CPU Ratio Control to manual
Ratio CMOS Setting to 8
FSB Strap to North Bridge to auto
FSB Frequency to 400
PCIE Frequency to 100

DRAM Frequency to DDR2-800MHz
DRAM Timing Control to manual
CAS to 5
RAS to CAS 5
RAS Precharge to 5
RAS Active Time 15
The rest of memory timing to auto, maybe tRFC lower then 42.

CPU Voltage 1,40
CPU Voltage damper Enabled
CPU Voltage Reference 0,63X
CPU PLL voltage 1,50
DRAM voltage 2,1
FSB Termination voltage 1,40
NB Bridge voltage 1,55
North Bridge Voltage Reference 0,67X
SB Bridge voltage 1,05


With this you get FSB 400, multi 8 , CPUspeed 3,2GHz and memspeed 800@5-5-5-15, it´s a good start.

Then you can start bring up your FSB and with it "CPU Voltage" (I should say 1,50 as max) and DRAM voltage (check your max volt on those memory first, 2,2v should be fine, maybe 2,3v), it should not be that hard to reach FSB 425, 3,4GHz and memspeed 850 and check with Prime95 and Memtest on your way up.

Keep us posted about your progress

Some settings I was not sure about,
cpu voltage demper, was not in the list
SB bridge voltage, was not in the list aswell

these were in my bios:
Clock over charging voltage
Load Line callibration
CPU GTL voltage reference (Think this is CPU voltage reference)
NB GTL voltage reference (Think this is NB voltage reference)

First, go to "User CP", "System Information" and "Edit System" and put in your system.

I have P5K Premium as reference and you only state P5K so I though it be the same, what board do you have, is it vanilla P5K?

Clock Over Charging Voltage should be auto.
Cpu Voltage Damper is the same as Load Line Calibration.
Do you have any SB voltage at all?
CPU GTL Voltage Reference is the same as CPU Voltage Reference.
NB GTL Voltage Reference is the same as NB Voltage Reference.

I have checked again, and I did not found SB voltage, is it important to continue?
I just found that a bios update deleted that option:

No it´s not important, you don´t have that option on your board.

I missread about your CPU, though you had a quad but it´s a dual so you CPU Voltage should be 1,40@3,2GHz to start with, then we have to see about how high you can go because you only have 3 phase power to CPU on that board.

Okay, I'm running now at 3.2GHz
I've ran orhos, after 4 seconds it crashed so I'm back at my previous settings >.<

What´s your temp with load at 3,2? Check with Core Temp or Real Temp.
If you have 60 or above you have to get better cooling before get higher, if you are below 60 get your CPU volt to 1,50 and DRAM volt to 2,20 and raise your FSB to 405 and check temp stability (use Prime95 25.6, small FFT), if it´s okey, go to 410 and check temp and stability, if it´s okey, go to 415, i think you get it.....

If you can´t boot you may have to change your DRAM freq, so you get close to 800 and keep push FSB.

When you have reached temp 60 and stability, your on the safe side, you can go higher but it´s a bit risky because your CPU start to degrading.

When you have reach your max CPUspeed we can OC your RAM.

Here´s some reading about how to OC.

How long did you run Orthos?

Probably you have to get your CPU volt up to 1,45.
