New to OCing and have a question

post #1 of 10
Thread Starter 
As the title says I'm new to over clocking, well i downloaded AMD Over Drive and in the Performance Controls under Clock/Voltage the only options I can adjust are the Ht ref. Clock, PCIe Speed, NB Vid, and DDR. I have no idea what these are, I moved the HT ref from 200 to 205 and my core speeds went from 2824ish to 2885ish, Im running a stock cooler and I just want to know what are safe limits to these options so I dont fry out my CPU. BTW its a Phenom II X4, any help would be nice.

First off, if you don't know what the Ht clock, PCIe speed, NB speeds, and so on are, you need to stop and go read up some more.
Second, you should be overclocking in the BIOS, some people use Overdrive to tweak in Windows, but I much prefer just using the BIOS, as Overdrive never even worked for me.
The stock cooler should let you get a reasonable overclock, but download something like HWMonitor, and make sure temps don't hit 62C on the cores. Be really careful with the Vcore, only raise it by intervals of 0.02v or less if it's your first time.

In the meantime, you should fill out your computer specs in your signature using the Rigbuilder at the top right of the page, so we know what hardware you're using.

And three Overclock on a stock cooler is not a good idea.

It's not necessarily a bad idea; some stock coolers can handle a little extra heat.

First off before you know anything. Know this- Use the bios for overclocking and not any software. Which Phenom II x4 do you have? what motherboard do you have?

If your motherboard does not support overclocking, I'd recommend you buy a new motherboard. You should be overclocking with the BIOS only. Temperatures are really the main thing you'd have to worry about though, that and overloading the VRMs.
Again, 62C is the max for most Phenom 2s, and you shouldn't be bringing Vcore above 1.5, especially if you've got lower end VRMs, and your board can't support those voltages, but your cpu temps would likely cap out much below that voltage with a stock cooler.

I've managed to get it up to 3.2 but I dont feel comfortable taking my Vcore voltage up any more to keep stability, but im happy with that. I wasn't trying to push 4.5 or anything, just wanted to open it up a little above stock. Now im messing with the PCIe Speed and i really have no idea where the limit is on this

You won't get great gains from that, and you'd probably be better off with core speeds and such, especially if you don't know limits.
Remember to stress test, use Prime95 with blend/small ffts, and run for at least 6 hours to ensure stability. AT LEAST 6 HOURS. Also, get HWmonitor to make sure your core temps are within acceptable ranges while this is going on.
