Im getting new components soon (well not that soon but meh) and i want to OC my curent build and see how it runs, i have no idea how to do it.

Can i please get taken through it step by step.

Can my build can handle it? (Rig In the Sig)

Thanks for any help guys

The steps to OC and AMD CPU are alittle different

I guessed it would be, after looking at your article Dan whcih concentrates on Intel :(

I have had a look at the articles (wow they're huge) and come to the conclusion that im still not sure what to do, i have to go into the BIOS?

lol, yes. The first half of the guide just explains what the various components are and do.. Ok first is the Hypertransport. Similar to the FSB of intel but faster. You change the speed of this to get an overclock.. 200mhz to 240mhz for example. Next is the hypertransport multiplier. This is the number you use to get the effective speed of your CPU.. 200mhz x 9 (multiplier) = 1800mhz. Then comes the HT link. The HT link is the speed of the hypertransport bus. It has it's own multiplier. You take the hypertransport And multiply it by it's multiplier to get the effective HT link speed (common speeds are 200x4=800mhz, 200x5=1000mhz) When you raise the hypertransport to oc you are raising the HT link, for example 240. 240x4=960mhz.. You're motherboard will have an effective HT link speed and you should try to keep it as close to this as possible.

One other thing is that the RAM is also connected to the Hypertransport.. Your RAM is ddr or double data rate. I guess you could say it also has a multiplier which is two, you can't change this however and if need be you will have to stick a divider on the RAM. A divider is capable of reducing the speed of your ram to keep it stable. Say I turned the hypertransport to 260, had a multi of 10 and reduced the ht link multi to 3 (260 x 3 = 780 Close enough to the 800mhz HT link my mobo says is best.) My RAM would still be running 260.. My RAM can't handle this. I would then have go to the RAM divider options and make the RAM run at 166 instead of 200.. So the 60mhz i added to the hypertransport would then be added to 166 instead of 200 for the RAM. MY RAM can handle 226 so i'm fine.

Last is the voltage. Let it be said if you raise this it can allow for higher and/or more stable overclocks. I didn't have to touch the voltages so i'm lucky.

I don't know if this makes any sense to you cause i'm not an expert at explaining things but i tried.:) Let me know if you need any clarification.

P.s. if i missed something feel free to add... I'ts been awhile lol

This is amazing, thanks it explains it so much better than that website, so using my Specs, i can boost my 2.20 Ghz up to say 2.80 Ghz? and then what would i do to my 400 MHz RAM?
 
I dont know if you will get a 400mhz jump or not without raising the voltage, depends on the processor. As far as you ram, drop it to 333 from 400 because when you raise your bus speed your ram will overclock to
 
whoa.. slow down.. i'm not sure you can get it to 2.8 without a voltage increase. You may not even be able to get there at all. Try a multi of ten and a ht bus speed of 240. Then download and run prime95 for half an hour to an hour.. if it passes up it some more...

Oh and you dont need to do anything to the PSU :P

A multiple of ten, so you mean i should go up to 2.30 Ghz first, put me ht bus speed on 240, boot up windows run prime95, torture test and waht am i looking for to tell if it is any different?
 
Yes, put the hypertranport on 2.4 (in your BIOS it may be called the core clock or the refernce clock) multi on 10, bring the ht link multiplier down by one and put a divider on the ram (just to make sure the ram isn't bottlenecking) Boot in, and run prime95 it'll tell you if it's not stable. If something goes wrong yank the CMOS battery on the motherboard for 30 seconds and put it back in. Sorry if i'm getting less coherent, i need to get some sleep lol

Hmmm so raise the CPU to 2.80 Ghz and reduce the ram to 333, what do i need to do to the PSU then?

Dont jump to 2.8 right off! Go into your Bios set your Hyper Transport to X4, then set your ram to 333, then start upping your (bus) most bios still call it you (FSB) speed from 200 just a couple of mhz at a time. And what do you mean what do I do with my PSU?
 
If by power settings you mean voltage, you can raise your CPU voltage a little after you raise your bus speed to the point your CPU get unstable. But just make sure you keep a eye on your temps.
 
Here are my CPU-Z stats: After changing to 2600

I tried different multiplyers in the BIoS as i didnt know what else to cahnge, im going to cahnge them back now and take pictures of my BIoS Screen.

This is what i got after putting the multiup to make it 2600 but on the screenie above it doesnt say i changed it :(
Prime95 Results: (After changed setting)

Ah what! i just went back into BIoS and it said nothing had changed, so them screenies above are my PC at normal :)

But i just did exactly waht you said, made sure the settings are correct and my PC didnt do Anything When i botted it up, so i just took out the battery, waited, and after i put it back in again, came to a command decision!

My PC wont do it because it doesnt like me, so thanks for your help guys, but im not going to bother! :)
