Dos program for checking what the FSB is?

[radman3d2]

I think I know the settings for 112, 124 and 133 but I would like to know before letting it boot to windows. If it is the wrong FSB, i.e. 133 my ram cannot handle that and it corrupts the registry. I'm pretty sure there is a program out there but I cann't remember where.

Unfortunately, CPU FSB and SDRAM frequencies cannot be _measured_.

Mainboard specific software could read the current mode the clock synthesizer runs, and _determine_ speeds from there. However, no two clock synthesizer chip types are the same.

As for the FSB ... the CPU core frequency can be measured in a generic way pretty accurately. Most modern CPUs also have a readout register showing the multiplier they run at - which by simply dividing those two numbers, gives you the CPU FSB.

Yet still, even if you know that, you won't find AGP, PCI, ISA, IDE, or SDRAM speeds by any generic method.

(The above is why programs like SiSoft Sandra are so often so helplessly wrong in their bus speed displays - generic software can't do much more than a wild guess ...)
