New Guy in the OC world. Originally AMD Phenom II X2 545. Unlocked to X4 B45

post #1 of 5
Thread Starter 
Hey guys, I'm new to this whole overclocking deal. About a month ago I was reading on how to unlock AMD Phenom II 5 series CPU's and I guess I'm one of the lucky ones. I managed to unlock my Phenom II X2 into an X4! Since then I've also bumped it up from a stock 3.0ghz to 3.6... there in lays my problem. Like I said, Im new to this whole thing, So, I have no clue how well I've done it. I have successfully ran about 6 hours in prime 95 without any crashes or errors. Anyway, long story short, Here is my current setup and any tips / criticisms would be greatly welcomed and appreciated!

I had a 555 myself a while back but it would only unlock to a tri-core. Still a good little chip and would run 3.9 all day long.

3.6 is a healthy clock but I bet its got a little more in there. Hard to get a read on your temps because unlocking cores disables the CPU temp sensor so you have to go off the motherboard's socket sensor instead. Itll be a few degrees higher than the actual core temp so keep that in mine.

Dont forget to crank up the CPU/NB as Phenom II's get a decent little bump in performance with it overclocked. 2600 MHz is usually the sweet spot.

Dont worry too much about the HT Link speed as it doesnt really do anything for the performance of a Phenom II. In fact you can turn it down to 1800 MHz and it can give you a little more headroom in overall core clock.

Yeah, Temperatures have been my main concern so far while messing around. I hate how unlocking disables core monitoring. Luckily, I've got an awesome case and a pretty decent aftermarket cooler, so I've been staying around the high 30s even under load.

Thanks for the advice, I'm going to mess around with the NB settings tonight and see if I can bump it up a bit more.

So I decided to take another look into BIOS and take your suggestions on bumping up the CPU/NB but I'm not 100% sure on what that would entail and I'm not really comfortable enough to just start making changes on my own without knowing what I'm doing. I think I found where to do this, but I don't quite understand how I would reach the 2600 MHz value you mentioned earlier. I took a couple pictures if you wouldn't mind sharing some knowedge tiredsmiley.gif



(And then if I were to click on 'CPU NB Freq')


Thanks again in advance!

Sorry I never did answer here.

Yes, that is the CPU/NB multiplier. It is tied to the FSB clock. So if you have your FSB at 240 MHz and have a x10 multiplier for your CPU/NB, youll have a 2400 MHz CPU/NB. You should have more values than x10 though cause x10 is usually the stock setting. That would mean you wouldnt be able to get a CPU/NB any higher than the FSB speed which usually wont go above 240 MHz on most boards.
