Increasing FSB and Heat

Ok I am looking to increase my FSB of my A64 to 1Ghz up from 800Mhz. How much more heat am I looking at? I run pretty hot as it is, but I was just curious how much heat/instability this will add. I dont really wanna try it quite yet without an idea of what I am doing.
 
What kind of cooling do you have? What kind of RAM? That's sort of a big jump. I don't know much about your board/CPU combo, but is that keeping a 1:1 FSB:RAM ratio and stock multiplier? If so, it doesn't sound too likely.
 
From what I have read A64 's arent good overclockers. Especially the FX's. I'd just leave it at where it is. You already have a kickass system.
 
EDIT: Im not talking about overclocking the CPU in the way you are thinking. Im talking about raising the FSB speed... Also the FX is a better overclocker then the others, it been giving higher speed and has multipliers to help.
 
Sir, you shouldnt even own this chip.

First of all, I know what I said did sound stupid, but you sir do not unstand what I am trying to get across. The Athlon 64 FX-51 has 1600FSB, correct? Well, This was sort of odd to me that you can increase the physical FSB in this BIOS. I believe it has to do with the ondie memory giving this option. I was wondering if anyone knew what the result of chaning this would/could do. I got this option after I flashed my BIOS. Yet it says 800Mhz because it has dual channel memory and 800x2=1600FSB. I would appeciate it if you dont flame me because you dont understand.
 
well im sorry, but when someone says "im not overclocking... just raising the fsb," and has a 700$ chip, i feel like punching myself in the face for the stupidity of humanity
 
raising fsb is overclocking. there is two ways to overclock, fsb or multiplyer.

dual channel memory configuration does not double the FSB speed. and increasing the FSB does overclock the CPU, because overall clock speed is the product of multiplier*FSB.
 
Well hell, Now I am even confused... My FSB is set to 200 and my multiplier is 11. Which gets the 2200 clock speed, I know that and have known that for years. What I am trying to say is that I am looking to increase is somthing differnt. It is currently set to 800Mhz and it is labeled "CPU speed". What I figured it is, is the FSB speed which is 1600 on the FX, however it becomes 1600 by 800x2 because of the dual channel memory, which I am positive about.
 
whats set to 800MHz is the hypertransport link between your CPU its actually set to 200MHz with a 4x multiplyer and is what your processor derives its clockspeed from. so if you raise this you will raise your processor speed and be overclocking.
 
Hmm...So I have 2 places to change my Hyper trasport and one of them is labeled "HyperTransport" and the other "CPU Speed"...

I think the one that I am talking about is the FSB, like the P4s have 800Mhz, G5 has 1Ghz, A64 has 1.6Ghz(800x2).
 
I knew I was using the wrong term, but everywhere I went to try to look it up it said FSB... *blushes*. So, would it help to change these, and would there be heat or any major problems occuring by doing this.
 
if that increases, subsquently, your clock speed will increase as well...unless u have an unlocked multi and lower your fsb
 
Will any instability/heat problems arise or will i need more voltage and how much clock speed gain will it equal out to? Yes, Multis are unlocked, but they arnt an option in this BIOS ver or the previous one.
 
Ok, so now I admit, I made a mistake... The option set the multipliers. You set the FSB then you choose the speed you want and it automaticly set the multiplier accordingly. I decided what the hell and tried it out. Sorry for any that I yelled at and for my stupidity. :(

Hmm, that's strange. Well at least you're shedding some light on the new Athlon64 nuances for those of us who don't have them yet.
