Tbird 800 @1000 and checksum errors?

[dwango]

I'm running a KT7-raid mb, and I just pulled the pencil trick with my TBird 800. It posts fine at 8,8.5,9, and 9.5 X 100 with the voltage at 1.75, but as soon as I try 10x100 at 1.75, I get a BIOS ROM checksum error (Insert system disk and press enter..). Any ideas on what this might be? Could it be that I didn't connect the bridges well enough? Thanks for any help.

I have a slotA Tbird 900@1100. I had to up the voltage to 1.85.
