Hi all.

I know this is not a Watercooled related question, but Id prefer to ask here as everyone seems more friendlier and able to help than other sites!

I have an E5200 (2.4GHz Standard) with a ASRock G31M-S Motherboard. I am very new to the idea of overclocking. I have used the ASRock OC Utility, and for the overclocking side of the utility it only has the option to change the CPU frequency and the CPU Ratio:

I have left the Ratio at 12.5

and the frequency is now at 260

It is now running at 3.25GHz Aircooled and staying around 32 Degrees Idle.

Does it matter that I have only changed the Frequency and nothing else? As I've always seen guides which are more in depth and require more changes. . I have been stress testing this and it has been fine and staying around the same temp.

Thanks

Rich

First of all I'll say I'm unaware of the capabilities and quirks of that particular processor...

If you've managed to get that far by changing BCLK alone then that's great... altering voltages isn't necessarily required, especially at more conservative overclocks. You will find you'll need to tweak more further up the line to maintain stability.

It's load temperatures more than idle you need to pay attention to, though.

I presume you're stressing with Prime95?

You want to stay under around 75 degrees according to this.... I generally clock to around 5-10 degrees below that to allow ample room for variances in ambient temperature, though this is largely down to personal preference.

I think we all know this ;)

Forgive me If I'm being slow but I don't quite follow...? Wrong terminology? :)

I should add that the reputedly best way to clock is via BIOS rather than with Windows tools... I've read that you can sometimes push an overclock further in Windows if the speed you're trying to attain won't POST, but that's more for bench runs and extreme overclocking.

I'm not familiar with the capabilities of that motherboard, but in general the E5200 is capable of a 1GHz overclock.

To obtain this you will need to enter the BIOS to change the FSB frequency and the CPU voltage.

Never used Prime 95 to be honest, had another program on the go which stresses CPU RAM etc, and under 100% load for 30 minutes, the temp went up to around 35 degrees. Thanks for the reply! Wasn't to sure if it was dangerous to change the one parameter without upping the voltage!

Really not to sure what this means

Ah thats wicked thanks, not to sure if it made much difference to do it in Windows rather than BIOS, wil have to do some reading up on it before I attempt the ol' BIOS side of things. Thanks!

Probably less dangerous to run without voltages if anything, although you're incurring a risk with any overclock. My personal feeling is as long as you're careful and know your platform well, the risks are minimal.

Don't be overly ambitious with voltages, especially on air.

Obviously I can't rate your software as I don't know what it is, but I'd suggest running "In place large FFT's" in Prime95 and see how comparable your temperatures are.
