OCing Athlon XP 2800+

Hello,
I'm new to OCing. I've read OC 101 and another guide somewhere on a google search to learn the basics. I've dabbled a bit but I can't seem to do any better.

My specs:
Mobo: Asus A7N8X Deluxe (2.0) (that's with an nForce 2 Ultra 400 Chipset)
CPU: AMD Athlon XP 2800+
RAM: 2 x 512 mb DDR (No name brand and Nanya Technology?)
PC 3200+ Running at 200mhz, 8/3/3/2.5

I have stock fans and nothing really special to mention. VCore is currently running at 1.7 V (Default was at 1.65) and the DDR Voltage is at 2.7 V (Default of 2.6)

I increased the FSB which was set at 166 to 200 and multiplier down from 12.5 to 11. Went from a core speed of 2080 mhz to 2200 mhz. I can't seem to find a way to run it any faster however.
1) The memory's clock speed (?) is maxed out at 200 mhz. I can't increase the FSB because the memory's clock speed is locked at the same speed. So I can't seem to increase the CPU's clock speed.
2) I can't increase the multiplier. As soon as I increase the multiplier and try to boot past the BIOS I get a BSOD.
3) The CPU is running at about 38-40 C idle time and when I run Prime95's torture test, it easily reaches 65 C. If I increase the voltage for the CPU and/or RAM while increasing the FSB it becomes incredibly unstable (although it does boot into Windows) and crashes soon afterward. If I increase voltage and the multiplier, it'll run but at hot temps. Idle is about 50 C and running the torture test I got to 73 C (!) which is when I decided to stop. The max temp for my CPU is supposedly 85 C where it melts down or something.

What can I do? Any suggestions? I'm a noob to OCing so it could be something really simple. If you have any questions I'll be glad to elaborate.
 
Have fun trying! Your model cpu is locked. With the exact same model board here the Atholon XP3200+ managed to squeak out from 2.205 to 2.3ghz when it was tried. The best models for OCing in the Socket A line where the XP2500+ Barton cored and a few Semprons. After a reseat of the cpu that once 61C for an idle temp and climbed to 73C during gaming with no OCing involved the max temp of 85C was never reached. But that was soon resolved with the addon of a larger then stock 4" square sink and 92mm fan combo.

One of the best tips found on some OCing forums is to back off on both memory timings and multipliers as well as voltages to experiment with raising each one separately to it's max. When you find the right combination you are then at the peak of what you can go to.
 
Hmm

Why did you lower the multi? I am sure it will work with the multi @ 12.5 and that will surely give you more speed :P

JAN :D
 
Ya Clutch that's EXACTLY what happened to me. I'm at 11x200 mhz and when I try for 2300 mhz it gives me a BSOD.

Alrighty PC Eye, I'll give it a try ;)

I will also try your advice jancz3rt

I didn't say that the 2800+ would make it to 2.3ghz. What I was mentioning was trying to see how far I could go with the 3200+ on one system here. That managed to budge up from the default 2.205ghz to a max of the 2.3ghz. But the method described there was tossed this way on an OC forum. If you find the right one to be on those guys can walk you through it. Just don't cook anything in the process.

No you didn't. Clutch mentioned it, that his 2800+ wouldn't run at 2300mhz :P

With the 3200+ being a locked model 2.3ghz was the max without seeing the system lock. When the memory timings were lowered to 333mhz the 3200+ was then seen as a XP2500+. The max was 2.3ghz with the multiplier still at 11x. Sorry about the mis id there. :P
