Need Help For OverClocking AMD 64 ...

It helps gaming, but not nearly as much as overclocking a videocard will.

Every CPU is different. There is no set amount you can overclock it. Some might be 10 Mhz, some might be 800 Mhz.

First off, get good case cooling. Then, makje sure you have a decent CPU cooler, and that it's affixed with Arctic Silver instead of the thernal tape it comes with.

Raise your FSB by 20 Mhz and see whart happens. Make sure the CPU doesn't get too hot, and see if it can run stress tests without crashing. then repeat.

There's alot more to it, like tweaking memory and hypertransport for stability, but those are the basics. Here is a good primer for overclocking the Athlon64s... READ IT ALL!

First off, such topics should be under "CPU"...just for future refernce.

Venice, Winchester?

Regardless, but the 90nm should produce better results.
The stock cooling coming with current A64's is quite capable actually.
Before I had my Zalman 7700, I had to use stock.
I applied some AS5, and did a proper burn in trying to find a stable OC
while lowering the Vcore. I was @ 245 x 9.5 idling 36C load 45C when I
finally got my HS/F. Keep in mind this was with a 3200+ though.
The biggy about the 3000+ is the low multi, usually meaning you'll reach
your limits on the CPU before you do on your Mobo or RAM.

2.2ghz would mean 3500+ speeds...however your not going to see a HUGE difference. But like above, if you make 2-2.1 on stock solutions, with acceptable temps...your doing just fine.

EDIT: Didnt thourghly read his post. @ 2000mhz, its possible heat was your issue. I doubt this highly. Could be your PSU, RAM...a multitude of possibilities.

OK , I OverClocked My CPU in 2 Ways :
1- I start the computer , press del to go to setup , then in cell menu there is an overclocking option (D.O.T=Dynamic overclocking technology) i use it in +3% , when i came to windows my cpu freq is 1856 (fromm 1800) Then I Go to Need For Speed Underground 2 and in about every 2 secends the system hangs for about 1 secend , i exited the game and disable the DOT
2-I go to Windows and use my mobo`s (K8N Neo 4 PT) OverClocking Program (Core Center) i OverClocked it to 1899 MHZ in FSB 209x8 !! and the Game Rus Cool !! without hitching !! but when i raise it to 1950 MHZ the system totaly crashed and have too use safe mode in order to make my computer Work !!
Now PLEASE HELP ME !!

Read my last post!
You don’t need to have some program OC for you!
You will NEVER get the best out of your machine that way.
You need to enter the BIO's by pressing the DELETE key right after the splash screen comes up and:

1. HTT multiplier should be deceased to 4 (from 5)
2. Ram Freq should be set to 333Mhz (from 400)
3. Increase your Vcore to 1.5, DDR SDRam to 2.7 and HHT to 1.25 or 1.3
4. Start raising the CPU frequency... You can probably safely start at 250Mhz, that will put your CPU@2250Mhz, HTT@1000Mhz and memory@416Mhz.

If you boot sucsesfuly, run Prime95 for 12+ hrs to verify stability.
If your system locks-up and wont boot after changing the settings in BIO’s, clear CMOS and try again at CPU@240.
If you run for 12hrs in Prime95 with no problems, go for 255, then 260 and so on.
I wouldn’t recommend more then 260-270Mhz.
Also remember to keep an eye on your CPU temps, you probably don’t want to exceed 60c under max load.
