Want to overclock my CPU, where do I start?

Turbo basically sets tighter timings in the chipset and memory.
Get the CPU stable before enabling this.

As you increase the CPU speed there will come a point where more vcore is going to be required.
Around 3Ghz i'll hazard a guess.



You will need to set System Voltage Control to manual.
Before you can adjust any of the voltages.

Yeah. It runs okay at 266 x 11 - 2926. well, it boots to windows. im stress testing it now to see how okay it really runs. i did try booting at 275 but i had no luck.

i think i'll stick to a speed that doesn't require any volt changes at first because this is my first punt at overclocking.
 
Not that difficult was it. :)

Probably the quickest way to find out if you need to bump up any voltages is to run Orthos or Prime95.
Prime torture tests will error very quickly if more vcore is required.
If windows reboots whilst loading up that's a good indicator as well.

I guess not! Thanks for your help. It ran okay with Prime95 (for 25 mins), so I'll try running Orthos and see if it errors quickly.

Orthos is just prime95 with a wrapper.
Check out the temps with coretemp while your running the torture test.

Yeah as I went to download it I read the home page, and the author described how he had simply edited the Prime95 GUI...

But I'm running it anyway!

With um, Core Temp 0.96.1 (Presume that's the programme you were referring to?) I'm getting Tj. Max @ 85C and both cores @ 60C. That's under load (Orthos). Is that okay or too hot?
 
Your temps are a little on the warm side but not a problem.
Guess you still have the standard heatsink that came with the e4500.

You now have contracted the OC bug and will be ordering a tuniq tower and a tube of AS5 :D
 
Oh dear, that's a shame. I actually don't have the Intel HSF installed, I've got an Arctic Freezer 7 Pro. Which aren't as good as that behemouth the Tuniq Tower... but they're meant to be okay right? I don't have AS5 on it, just the regular TIM that it came with. The case is a Lian-Li PC-65B...

Maybe I could try reseating the HSF... orrr I'm not sure what else.
 
Nah, its not that bad a temperature, nothing worth messing with unless you want to go much further. Would have expected cooler, but that may be because of a whole host of things, what temperature does it idle at ?

The arctic silver cooler comes with artic cooler thermal paste ;) lol

Make sure PCI-e frequency is on 100/101 (some like 109 for some reason) if you leave it on auto you may find your graphics cards getting beaten up.
 
hi

does anyone have a fix to or recomend another program rather than CoreTemp, that program does not run on windows vista 64 :-(

Oh right, I thought it was a bad temperature. So you just mean, it'll be okay, but obviously if I wanna go further I need to keep my temps down.

Well that's cool, I've upped the CPU 700MHz, and that's nothing comapared to what I've read about on these boards. But I'll settle at that, it's just a bit of fun. My graphics card is an old X1850XT... and so anyway, that's my bottleneck not my CPU.

Oh yeah, I hadn't thought about that with the Arctic HSF. So yeah guess it is AS of some sort on there!
 
If i dropped the multiplier to say 9, and increased the FSB to 333MHz, giving me about the same speed as before, will i get any increase in speed because of the higher FSB?
