Can't get >200 FSB on A7N8X-X

I've got a Mobile 2600+ and Corsair XMS 3500 (BH-5). I tried everything from 205 to 217 FSB and it always failed P95 (usually froze).

What am I doing wrong? Is there anything you have to set in the BIOS to lock the PCI/AGP (or is that automatic)? This is with the regular 1007 BIOS. I heard that upping the Vdimm can sometimes help. As far as I know there is no way to increase the voltage to the NB on this board in the BIOS. Any help would be appreciated. Maybe I'm overlooking something simple.

P.S. - All A7N8X-X versions are like the Deluxe V2.0 PCB in that they officially support 200 FSB and use the 400 NF2 Northbridge.

The PCI bus is automatically locked, what i would try to do is up the vcore and the vdimm and see if that helps and make sure that you dividor is set to something that equals 1.
