Auto-overclocking? sounds too easy to be true.

I received my new PC today and I'm at work reading the Motherboard manual. Now Iv'e been thinking about overclocking since I first ordered the computer and Iv'e read lots of the OC threads and one thing I do know is that overclocking is not easy for newbies what with volts and FSB and stuff however a part of my Motherboard manual is talking about auto overclocking which sounds just a bit too suspiciously easy to me it says :-

"AI Overclocking {Auto} Allows selection of CPU overclocking options to achieve desired CPU internal frequency. Select the target CPU frequency and the relevant parameters will be auto-adjusted.

Now correct me if I'm wrong but I'm reading that as saying all I need to do is tell the Motherboard that I want my CPU to run at 4GHZ and the Motherboard will adjust the FSB and Volts to automatically achieve this for me.

Does that sound right to you guys or am I missing something?

My Motherboard is a Asus P5K and the CPU is an 8500.
 
The Abit Digidice had a dial on the front you could spin around to 5 different settings varying the degree of over clock it booted with. While I am no overclocking expert, it definitely raised the processor speed with each indervidual point on the dial - So afaik, it worked fine :)
 
It will work but you probably wont get a massive overclock and it will more than likely over-volt the overclock... much better to do it yourself in the BIOS... Link in my sig should give you an idea about what BIOS options do what... although the overclocking is based around a Q6600 the principle with your E8500 will be the same (i.e. find the CPU VID, set that in the BIOS and raise your FSB till prime95 / orthos fails and then start raising the vcore / FSB together till you get the clock you want)
 
These auto overclocking options never work properly. They either overvolt the processor, or undervolt it. I tried it once to see what kinda voltages it would bring up, and it gave me a low and unstable overclock. Do it yourself, so you can get a rock solid system
 
Do it yourself, personally I don't like the idea of the BIOS changing settings itself, you don't know what it's doing. It might decide to slow down your RAM or overvolt your CPU.

There are plenty of guides on these forums alone that will walk you through every step.

It's pretty basic, the main FSB multiplied by the CPU multiplier determines your CPU speed. The FSB multiplied by the FSB/RAM ratio determines your memory speed. You have voltage options for your CPU and RAM. Basically the more volts you pump through the faster it will go but the hotter it will get. CPU voltage should never need to go over 1.45V, RAM voltage should never need to go over 2.3V.

You also have North Bridge voltage that can help an overclock. That voltage depends on your mobo and should never go up more then 10-20%.
 
Thanks a lot for the tips guys, I did have a little play around with it today (before I got back online and read all your new responses) and yep your right I could OC to 3.7 using the automatic system (Asus AI booster) but even though it gave me the option to go higher my PC instantly froze if I tried to and I had to force a reboot.

Now that Iv'e read your comments Ill take a more comprehensive go at the weekend using your advice/guides (I'm trying to get 4.0 and then Ill stop)

try these details

FSB :422
Multiplier : 9.5
Voltage :1.3v

Total Speed is 4.009Ghz

what ram do you have? Adjust ram to fsb ratio to keep the total ram freq as close to stock as possible, if it goes over stock, incease timings for example from 4-4-4-15 to 5-5-5-18.. and also make sure what voltage your running the ram at..

and how many sticks do you have 2 or 4?, if 4 you may get less OC and you will need to increase your MCH or northbridge voltage by 0.1v
 
Platinum87 are those the numbers I need to punch into my bios to overclock it to 4.009Ghz? OMG your a hero mate!!!! -you have saved me soooooooo much trouble and scary hours of waiting to see if my computer blows up or not :D

My ram is 2 sticks of Corsair XMS2 2GB DDR2 PC-6400 800 MHZ
 
Its probably worth mentioning that just putting platinum's numbers into the bios may not give you that overclock. From what i have heard, the E8500s clock very well, so i am sure you will reach the 4ghz point, but you may have to use different settings. I would use these as a starting point - you may be able to run at the same speed at a much lower voltage (or go even higher :)), or you may have to use a slightly higher voltage.

Also, with the high fsb speed, you will need to overclock your ram, as platinum mentioned. Set the ratio to 1:1 to keep it at near stock speeds. I built a machine using xms2 and it happily ran overclocked on stock volts/timings at around the same speed (850 Mhz ish..), so you may be fine, but if not, slacken the timings or increase the voltage a little.
 
I have started using AI overclock on my Asus board and found that when I manually overclock, I get same results speed wise, but the pc will not enter "Sleep" mode. With AI overclock, I get the same processor and slightly faster memory speeds and it also will sleep. I guess I fail at over clocking.
