Changing FSB and Multiplier

[Frodo Baggins]

Using AMD Duron 950 Mhz
Amptron K7-VMA MB
133 mb PC-133

How do I change the multiplier or FSB?
I thought that buy unlocking the Chip, I could change the multiplier and I could already have changed the fsb in BIOS be4 I even unlocked...

My BIOS's CPU PnP page has:

Brand/type/speed/core voltage/ratio/frequency/dram frequnecy

The problem is that the ratio and frequency are grayed out and I cannot change them....

Any ideas?
A problem in my unlocking?

Apparently, your board doesn't support FSB or multiplier adjustment. You may still be able to adjust it using a utility like SoftFSB or CPUFSB, availiable at www.tweakfiles.com.
