Easy way to overclock....??

Have just built my system and would like a quick and easy way to overclock it for the next few months while I get used to the new PC.

Don't want to go mad or anything changing things or risk breaking anything!

I have the Asus P5N32-E SLi board (I know it's not the best overclocking board) and it has loads of overclocking tools - one of them called AI booster.

It has auto overclock options ie 5%, 10% and 20% - can I simply just switch to one of these options ie 20% ! and the PC will do the rest and I shouldn't have any problems?

Any other easy wins without changing voltages and a miriad of settings?

I have 2 Gb of GeIL ultra low latency RAM 4-4-4-12, C2D 6600 and BFG 8800 GTX.

Would be great to get c 3Ghz one day !

Thanks !

Nic

I love a an with ambition - you should be able to get 3.4 with only modest voltage rises, and more if your cooling is good and you are happy to see higher temps.

But I'm terribly wary of using Asus' built-in OC tool, which I really don't trust. I would always advise doing it the hard way, so that you learn along the way. In your case, it will mean dropping the RAM divider (you don't say what speed it is) then raising the fsb. That board has a rather silly fsb setting system, where you need to multiply the real fsb by 4 to give the quad-pumped speed, which is what is actually set. Thus default for your CPU is (IIRC) 1067. If you want 2.5GHz, you need to set 1112 for instance: 1112/4 = 278 x 9 (the CPU multiplier) = 2502MHz. Test the stability at each change, then up the bus a bit more. Note that you need to raise the CPU VTT voltage to the maximum 1.55V for best stability. You may also need to raise the 1.2HT and NB voltages as well as the CPU voltage to keep stable. But only raise voltages when you have to.


If you fancy a rather boring read, then this is how I did my similar setup (same MB and CPU, different RAM).

knowing nothing about overclocking I would be too worried about breaking my new set-up to start changing things I knew nothing about!

I take it there is no easy way to get 3Ghz without full scale overclocking :(
 
I'm a bit confused about this board (well I'm actually using a P5N32-e PLUS), in the BIOS it seems that I can't set any options on the FSB but i can on the *** software?!

I just tried using the software to go upto 333 x 9, as soon as i tried burning in the CPU temp shot up to 70C! This is on a Scythe Ninja with a 120mm Nexus fan. The MB temp is reported as 39C.

Think I might leave overclocking until i've replaced this heatsink, i've not been impressed with the Ninja at all, the mounting was terribly difficult. I'll probably wait until the new thermalright coolers are out and get one of them.

Have you read the BIOS section of the manual?
 
I have just bought this board and am trying to overclock a 4300. So far up to 270FSB without any troubles but after setting 290, I keep getting lockups in Windows. The cpu is idling at around 40 degrees which seems ok to me. I have all the voltages on auto, should I be setting them manually?
 
any tips as to exactly what to set it at or is it just trial and error? CPU-Z showing 1.328V currently.

RAM is kept at 333MHz (DDR5300). C1E is off, speedstep is off, PCI-e is locked at 100, spread stuff is off.
 
Essentially trial and error. Raise the fsb slowly and test at each point. If the system is stable, leave the voltages alone. If it gets a bit twitchy (crashes, locks etc) then raise the CPU voltage about 0.0125 and try again. If a couple of those fail, raise the NB voltage a notch, and if that fails try the 1.2HT voltage as well - all seem to make a difference.

I should also point out that CPU are pretty hardy as long as you watch the temps. Touch wood 've never wrecked one, and I've run them for months at 60oC and higher (one AMD chip used to cruise at about 78oC)

What are you using to measure the CPU temp? AsusProbe is about the best, but still a little unreliable. But that temp seems massively high: I'm at 1.5375 with an Infinity in an Antec Nine Hundred case and the CPU is at about 51oC full load.

Start off with 1.4V and work up slowly. My own experience says you'll need 1.45V to get over 3.2GHz.

Was using coretemp. Have now installed the Asus probe thing and it reckons my CPU is at 35C. Is that normal? Is 40 really that high for idle?
 
As far as I know ASUSProbe only measures the socket temperature, not the core temperature. Intel Thermal Analysis Tool (TAT) is the only proper measurement program, but CoreTemp, PC Wizard 2007 and the latest versions of Speedfan all also read the core temperatures as well.

40C is not a high idle temperature on air cooling.
