System spec:

AMD XP 2400+
Asus A7N8X (nforce2)
2*512 PC3200 RAM
Hercules 9800 pro
Aircooled

CPU:
AXSA2400DKV3C
AIUCB0241XPBW

Now I thought that my processor should be unlocked, because it's on a nforce2 board. But it seems not to be so.
When I change my FSB and multiplier the system doesn't post, just a black screen..

Next to that, my RAM is running at 133Mhz, shouldn't it run at 200 ??

Thanks for any answers/advice.

AMD's after week 39 are locked, no mobo in the world can unlock it. If you had a VIA chipset, you could mod it into a mobile.
The RAM is running synchronous with your FSB (FSB=266DDR so 133MHz).

//edit; hm, was that lock introduced in 2002 or 2003 ? Try lowering the mult and leave the fsb.

I have the same problem, but only after I switched my memory sticks. So I know my cpu is unlocked but I can't change the fsb anymore uke:
with my previous sticks it was no problem reaching 200 fsb with my barton 2500 on my nf7

Ok, I lowered my multiplier from 15 to 13 resulting in 13*133=1730 mhz

That worked fine, so I guess it's unlocked.. What Might be the problem causing the black screen then?

Also, I can't increase my FSB by 1. I have to select either 133 166 or 200.

Thanks for any help.

if I remember well, you should select advanced or manual somewhere.

Kay I think i solved my problem

For the people with the same problem:

Black screen is caused by too low vcore settings, increase it.

And to be able to increase FSB by 1 on a Asus A7N8X you have to go to advanced chipset features --> system performance --> user defined.
