Basic Steps to Overclock AMD 64's

Ok after reading alot of forums and some of them being more confuseing then others I stayed up one night with a calculator just typeing in numbers until it finally clicked and I understood how to overclock the Amd 64. Now you can go to other overclock post and read the terms Im just going to go step by step in what I found to be the simpliest way to raise your cpu speed.

Step 1: Go into Bios
Step 2: Find your HTT multiplier it is between 1-5. Depending on your motherboard depends on where this is set stock. For nForce 4 motherboard the stock is 5 x 200 which equals 1000fsb. You do not want to have those two numbers to equal over 1000fsb.
Step 3: Now on the stock nforce4 motherboard 5 is the stock HTT multiplier you will want to lower this to 4 so that you have some space to raise your HTT without going over your 1000fsb.
Step 4: Raise your HTT which will be 200 usually 3-5, restart your computer, and test it with super pi(1million test), and prime95(for about 10mins with max heat test). If everything goes well then keep raising your HTT 3-5 until you get unstable then raise your vcore just alittle usually just the next step up will do. And try it again if still unstable raise vcore again until it either gets stable or if you exceed 50C. If you do get this far it is proble a better idea to lower your overclock down and lower your vcore with it until you find a good spot where it is stable.

With doing this you should be able to overclock your system. I know this proble isen't the very best guide but overclocking a Amd 64 is way different then overclocking any other cpu with the new HTT technology. If you are able to push your HTT to 250 with a HTT multiplier of 4 and you still want to go farther make sure you lower your HTT multiplier to 3 or you will exceed the 1000fsb.

So nForce4
Stock 200 time 5 equals (1000FSB) <----Limit

Overclocked HTT of 201-250 will need HTT multiplier of 4.
HTT of 251-333 will need HTT multiplier of 3.
HTT 333 or higher use HTT multiplier of 2.

Main thing for AMD 64 system don't let the HTT multiplier and the HTT go over the motherboard FSB or it will most likely cause problems in the future.
 
Have a read :)

Not all NF4s have a 1000MHz HT clock ... :) (some run 800)

There's not all that much different really (related to the HTT)... the only difference is the ondie memory controller which means that the memory clock is set by divider rather than a independent clock ... one could argue less controll ... or argue less nuisence...

Actually, the A64s dont have a FSB :)
 
Actually preator they do still refer to it as the FSB but really it is the Hyper Transport. As in the specs for this Asus A8N-SLI board
http://www2.newegg.com/Product/Product.asp?Item=N82E16813131524

It shows the FSB 1000mhz Hyper Transport. So really your just corrected me as in useing a more advanced term :) But still the point stays that you do not want to go over the 1000mhz FSB or Hyper Transport with the HTT multi and the HTT.

And yet ok some might have a 800mhz I have not looked it up because I do believe you but the point went across not to go over that limit.
 
For a more A64 specific overclocking 101 guide have a look here : http://www.insanetek.com/index.php?page=overclocka64

Not to crap on anybody, but it shouldn't be allowed to write guides in detail over ANYTHING until they have been reviewed by the site mods (whoever is in charge of proofreading) and approved to be published.

That's just what i think though, not up to me. Just when a step by step is cut to pieces because of errors and mis-information it doesn't really help anybody.
