Tyan Trinity400 1854 ram/dramclk/bios problem??

[ytay99]

System Specs:
Intel Pentium III 450mz/100mhz Slot 1
Windows XP - dual boot two hard drives, both winXP
512 megs ram slot 0,1 with 256megs/pc133
32 meg video diamond stealth 540

Bios - Version 1.07
Motherboard: Trinity400 1854c

Problem:
When I boot up my dramclk reads 66mhz, if I try to adjust the bios setting
to to read host clock(it automatically adjusts it to 100mhz), I get the
following message when i boot up on either drive
STOP: c0000221 Unknown Hard Error
\system root\system32\ntdll.dll

if i try to adjust the clock to +33mhz the computer will not boot at all and
i have to reset the bios

not being an expert i would assume I should be at least be able to run mt
system at 100mhz, but it will only boot @66mhz. I am assuming there are some
bios setting i am applying incorrectly, as I have tried a myriad of settings
with no luck. Also with running pc133 ram, is it possible to run my dram
clock @133. I think I have included all pertinent info, let me know if I am
missing something

Thanks all,
Dave

Just try it one memory stick at a time and see what happens.
