General overclocking questions from a novice.

post #1 of 11
Thread Starter 
I've recently bought a few upgrades to replace my ageing 775 (1090T, M4A89GTD PRO/USB3, 8gb XMS3 1333) which I believe to be a very 'overclockable' setup and I have a few questions I'd really appreciated getting some help with, the only overclocking experience I have is bumping up the FSB on my E8200.

1. I understand the 1090T is an unlocked (BE) processor meaning the multiplier is unlocked, I understand the general overclocking procedure (increase multiplier, check if stable, if not stable increase voltage and repeat, once at desired clock reduce voltage until 100% stable) but do I touch the FSB at all with an unlocked processor? That's the difference between overclocking via FSB, multiplier or a mixture of both, does one of the three options have an advantage over the other?

2. I've seen quite a few people claim that overclocking the north bridge will give you a snappier computer overall rather than just overclocking the CPU, how do I go about doing this, and is it as easy as a CPU overclock and does it require the same technique?

3. RAM, I've never touched the voltage/mhz/timings of any sort of RAM, the only experience I have with this is setting the ram ratio to 1:1 for my E8200 (or something like that), when I overclock the CPU I assume the RAM automatically follows and bumps itself up to accommodate but will I have to set the mhz myself or do I not touch it at all? And are there timings I should be aiming for, the lower timings the better?

Thanks for any replies, I greatly appreciate the help, it's a very daunting task for me, thankyou!
P.S, I'm reading the 'Phenom II overclocking guide' right now and it's a very helpful thread but it is lacking in a few aspects.

1. Overclock BE CPU's is easy than normal ones but set 19x multi for 3.8GHz and increase with FSB to 4GHz, example : 19x211 = 4GHz. You'll get better ram Speed.
2. Northbridge overclocking is like cpu overclocking if it's isn't stable increase voltage and test again. The best Northbridge with Higher performance is from 2600~3400. (but i dont recommend you to go to 3400 range).
3. Ram ratio doesn't changes something in AMD CPU's (DONT WORRY).

Start Overclocking...

I see, so once I get to a multiplier of 19 I should ditch that and go straight for FSB? The chip I bought is rated for 4ghz at 1.375v so I was hoping to get 4.2ghz on my H60 push/pull , I've heard that getting those 200mhz is really voltage intensive so it's usually not recommended, but I may aswell try for nothing.
The northbridge is the main thing I'm worried about, is there only options for changing mhz and voltage? If so I reckon I can do that, so I want to try and get 2600mhz if I can?

It's not rated for 4GHz with 1.375v. It's impossible to get 4GHz with 1090T on 1.375v. Your stock settings uses more voltage than that!

That's what he/she said, and he/she seems to be a respected member of this forum, here's a direct quote:

Not all chips are the same. Try with 1.375v if you want to fry your VRM's and CPU... ^^ Nobody stops you. As you can see the guy who done that had GOLDEN CHIP. Maybe your is the poor one (some poor ones get 3.8GHz with 1.55v).

How the **** are you going to fry your VRMs and CPU from using too low of a voltage? If that was the case half the forum would have blown something by now. Please don't spread garbage information like that.

@OP, disregard this guy.

It is basically just increasing multiplier and voltage until your desired clock speed/max voltage is reached. You can try inching out a couple more MHz with the FSB, and upping your RAM/Northbridge speed a bit that way. Many people do suggest upping your northbridge to ~2600Mhz, and value that over an extra 100-200MHz on the CPU. It's up to you to decide if it's worth it or what. And you should be able to just leave the RAM at stock, you can try to tighten the timings a bit after you get your CPU/Northbridge OC'd.

Thankyou that was very useful and answered a lot my concerns, anything over 4ghz I'll be very happy with so the extra northbridge clock will always be welcome, does 'tightening' the timings involce changing the actual timings of the RAM itself or is it automatically done when you increase the mhz of the RAM?

The quote is from the person's for sale thread, the exact processor I'm buying.

Yes because he is using too high CPU CLOCK with LOW Voltages (DONT MAKE ME ****) ok !?
