Hi, I am completely new to overclocking and I've just put together a new machine and I was hoping to get some help to get the most out of it. I went into the bios and was overwhelmed by all the setting to adjust... Please help!

So I have:

Asus P5E
Q9450

Does anyone have this board and cpu that can help me please?

Cheers

Raising CPU PLL on the P5E will allow you to get a lower vcore. For suicide runs disable static read.

Do us a favor and list your specs. We'll appreciate it and you can show off your rig.

Top of page => User CP => Add System/Edit System => let 'er rip

Take a gander at this too.

Wha...? Sorry, I'm a complete newbie. I can see these options in the bios, but is that all? I'm hoping to get a step by step guide or just someones settings to start and learn from.

I've added my system (most of it), so hopefully that helps.. Cheers

Should read one of the tuts in the intel forums here. They have some really good info. If you get stuck lots of people here will help.

But to start off set your memory to 5-5-5-15 manually. They're the first 4 memory settings in bios. Then give them about 2.2volts.
Set your nb voltage to about 1.55 volts.
Set your cpu vcore t0 1.3 volts
then start raising your fsb frequency in 5MHz increments until you can't boot windows or get the machine to post. Then either back the fsb down or increase voltages.
Oh and set the strap to 400 so that you run 1:1 on memory to fsb or set it to auto and select a memory speed that is twice the fsb frequency you dial in, which will have the same effect as running 1:1. Twice the fsb because you're running dual channel so their rated speed is 2x.
Just keep tweaking, and remember that higher voltage gives stability at higher speeds, but too high will damage your components, and as you speed up you processor, it will also affect your memory speed (overclock) your memory. Hope that makes sense.
When you do get a stable speed you like, then start lowing voltages and memory timings to tweak it even more.

Hey - thanks heaps. I'll give those settings a go and that thread a read!

Oh and disable the following settings whenever overclocking:
CPU Spread Spectrum
PCIE Spread Spectrum
C1E Suppport
CPU TM Function
Vanderpool Technology
Execute Disable Bit
Max CPUID Value Limit

OK, so I've applied those settings and the core speed is 3.4! Really happy with that, so I might tinker with it a bit later. Thanks for all your help!

What do these settings do exactly? I basically have the same CPU and MOBO setup as berrys

P5E, Q9450 overclocked to 3.41... running air with stock intel fan

Here are my settings and I'm running OSX 10.5.4

cpu ratio setting: 8.0
FSB: frequency: 425
BSB Strap to NB: 400
PCIE Freq: 100

DRAM freq: DDR2 850
Dram Command Rate: 2T
Dram timing: manual 5-5-5-15
everything else AUTO until......
VCORE Voltage: 1.24375
cpu pll volt: auto
FSB termination volt: auto
Dram Voltage: 2.1
North Bridge volt: 1.45
South Bridge Volt: auto

loadline calibration auto
cpu gtl reference auto
north bridge gtl reference auto
sb 1.5v voltage auto

cpu spread spectrum auto
pcie spread spectrum auto

c1e support disabled
cpu tm function enabled
vanderpool technology enabled
execute disable bit enabled
max cpuid value limit disabled

I think you have all info in users manual that came with your board...
Here is great info too: http://support.asus.com/download/dow...n-us&model=P5E

...btw, I started to learn about Ocing almost two years ago, and I still am...and nowdays see many guys that want to OC, and write about it in their first post, without any read, just ramp the FSB...lol I admire their courage...
