Tyan 1854c and dram clock

[ytay]

i have a tyan trinity400 1854c motherboard, my setup is as follows:
P3-450mhz
512 pc133ram (2 slots 256meg/ea.)

When i fire up my pc i see the following:
Pentium 3 CPU (100x4.5) dram clock 66mhz

should that not read dram clock 133 mhz to match the ram and if so what changes should be made in my bios. i have tried setting the dram clock to +33 but i get a blue screen, if i set it to auto-detect it finds it as 133, but again i get the blue screen. anyone have any ideas or does it involve jumper settings

thanks
