Undocumented 83 Mhz bus speed on QDI explorer II?

[Joeschmoe]

Here's the scoop:
I am running a QDI Explorer II mobo.
This is a jumperless motherboard that supports 75 Mhz fsb.
I am using a powerleap adapter with a k6-2 450 (at 450). (75 x 6)
I believe based on rumors I heard somewhere a few years ago when this mobo was new that there is an 83 Mhz undocumented fsb capability. How can I get at it if it exists?

Yes, making fun of this computer can be fun. So for your amusement, I am also running 96 MB of simms and a PCI TNT2 card. And believe it or not, I want it to be faster

Thanks all.
