Overclocking problem in Windows NT

[Rubbub]

I have a PII400 processor running fine in 100Mhz bus. So I decided increase the bus speed to 112Mhz. When the computer restarted, I can see the BIOS displayed PII450... Anyway, when I went into my OS which happens to be Windows NT4.0 with SP4. Running WinTune98, it says PII400. And checked the performance, the same as before. So I am wondering I Windows NT environment, overclocking is valid or not.

Try getting hold of an older version of SiSoft Sandra, that run in dos mode.

Overclocking is overclocking. Your OS has no control over it.

Go into "Administrative Tools" and then run "Windows NT Diagnostics"

That should give you the real speed. I've never seen it be wrong, but it is usually exactly 1 or 2 MHz below your actual speed for some strange reason.

The problem is my AMI BIOS. There is an option to disable overclocking.( actually it's an option to disable "displaying overclocking message" ) But somehow, it will disable the overclocking.
