Overclocking Noobism?

post #1 of 13
Thread Starter 
Hi guys im a noob to this overclocking business and have a question about overclocking my system:

Mobo: Asus P5B-V
Cpu: Intel core2 duo E6400 2.13Ghz
Mem: 2x ( DDR2 1024MB Pc2 6400 400Mhz )
Graphics: Ati sapphire x1900 GT

I want 2 overcolck this system and went into the BIOS.
I increased the CPU Frequency from 266 to 285, and wen i rebooted i saw that the core speed increased from 2.13 to 2.28Ghz.
Further increase of CPU freq resulted in boot failure.
Haven't changed other parameters yet.

Have I now successfully overclocked my system to 2.28Ghz and be a happy man?
Have I done something completely useless?
Should I continue tweaking memory timings and/or other parameters in BIOS?

Im a bit lost in this..

Thanx 4 advice on this..

You need to raise the CPU and fsb voltages to get a higher overclock.
Be very careful in doing this, I would find out what the limit is for a Asus P5B-V northbridge and what the maximum safe voltage is for your E6400.

Please fill out your system specs under your User CP so we can see what your other hardware is.

Thank you for replying.

In BIOS i see voltages:
Mem voltage
CPU Vcore voltage
FSB termination voltage
NB VCore
SB VCore
ICH Chipset Voltage

Increasing CPU volt in my BIOS means increasing CPU Vcore volt, and fsb voltage in my BIOS is FSB termination voltage?
I increased the Cpu Vcore Voltage to 1.4V, Cpu running now at 45 degs (was 40). Tried increasing CPU freq, but did not boot.

And will the increase from 2.13Ghz to 2.28Ghz have any impact?

Btw I disabled Vanderpool, CPU TM, PECI.

Thank u.

I think this mobo is just not made to handle overclocking...increased both CPU and FSB (NB) voltages. Could not even increase CPU Vcore voltage by 1.....

Thanx anyways peepz

Could you do some CPU-Z screens?

Increase the FSB frequency. Only increase voltages if you get a blue screen.

Those are my current Cpu-z screenshots.
Here's what I've done so far.

Increase CPU freq from 266 to 286 Mhz. This resulted in increase of core speed from 2.13Ghz to 2.28Ghz. Any further increase resulted in boot failure.

Next increased CPU Vcore and NB Vcore voltages to 1.475V and 1.5V respectively. Then tried to increase CPU frequency higher than the above 285Mhz which kept resulting in boot failure.

Increasing the voltages above mentioned would help increasing the CPU frequency. Just not in my case...

Thanks!

Its probably the ram, as you already running it at 428(x2), and its rated for 400(x2).

Try changing the divider, loosening the timings or upping the voltage for your ram. You shouldn't need that much voltage to bump up your CPU.

If you're vcore is at 1.4, you should at least be fine with that small of an overclock. Try a round number, 275 perhaps, or 300.

Can you increase the CPU Ratio multiplier? (looks like it's currently 8x) Try increasing that to 9, and lowing your core voltages to 1.4 for now. Try stepping it up 5 or 10 MHz (266 -> 270 -> 275 -> 280) each time and see how it goes.

If it's post's and boots, check stability with Orthos or Prime95, and lower the vcore as much as you can.
