my spec are
mb abit nf7-s rev 2 with 512mb pc3200 dual channel
processor athlon xp 2400+ video is asus 9550 ge 128/128mb sound sb live 5.1
hd 40gb.


I would like to oc the cpu but each time i try it won't let me oc the thing
could it be the cpu cant be oc or the mb won't let me .

so thanks in advance

Ok, I'm assuming the cpu is multiplier locked, so all you can do is oc the
fsb and memory.

These are all bios settings:
Softmenu page
CPU==User Defined
Fsb==200 (we'll start here)
Multiplier==whatever the stock is
PowerSupply==User Defined
CoreVolts==1.8v (just a starting point, you can probably go lower)
DDRVolts==maximum setting (you can't hurt ram by overvolting)
ChipsetVolts==maximum setting (same)
AGPVolts==1.7v
OverTempProtect==65C (whatever the lowest setting is)

Advanced Chipset page
Memory Timings==Expert
memory values == 10-3-3-2.5 (the 2.5 may be 2.0, depending on what you
bought)
System/Bios cacheble==Disabled
AGP Aperture=(size of videocard ram)
ThermalThrottling==Disabled
AGP Rate==4x
AGP FastWrites==Disabled

PC Health page
Shutdown Temp 65C (or whatever is close to this)
Warning Temp 63C
Shutdown CPU Fan Fail==Disabled

One of these pages has an entry for Clock Variation in % (I've forgotten the
term). Just disable it.
Disable any unused peripherals or ports

Report back on your results with these settings, please.

No. You just aren't doing something right. Multiplier x FSB = cpu speed.
Default for 2400+ is 15x133 (2000MHz). If your cpu isn't locked then you
should get 13x166 easy. If it's locked, then raise the FSB to about
145Mhz. You may need to raise vcore slightly for this.

That's an easy one. No need to try it. It won't boot. 15x200=3000MHz.:)

He may be able to get close to 166 FSB for 2500MHz, but I wouldn't count
on it. More like about 160 for a max (15x160=2400MHz).

haha, are you serious? That's the 2400+ default multiplier?

Yep, it's 15x133. Now a 200MHZ bus should work fine for a 2500+XP. it's
default is 11x166.

how the hell is a normal 2400+ 2 mhz when my 2600+ not oc'd is 1.9 mhz!

for the fsb i can't use more then 145 and even then its not looking right

Why agp 4x when the card use 8x ????

so i think i will try to get another cpu or another board ...

Athlon 2400+ (133x15) = 2000mhz
Barton (?) 2600+ (166x11.5) = 1916mhz

fsb and L2 cache supposedly

Because the 2400+ is a Tbred core and the 2600+ you are talking about is
a Barton core. The 2600+ tbred core runs at 16x133 (2133MHz) for the /266
model, and 12.5x166 (2083MHz) for the /333 model. Any of the tbred models
(including the 2400+) will outperform the Barton 2600+ in cpu intensive
task.

This makes no sense whatever. The barton has twice the cache.

Makes perfect sense. Cache isn't used unless needed. So if only 100K is
used for a task, which cpu do you think will perform beter, one at 2000MHz
and 256K cache or one at 1916Mhz and 512K cache. It's really that simple.
Just like the dual channel memory, extra cache is way over rated and over
hyped. Both only add minor improvements to performance. and actually are a
henderence in some cases.
