Need help with RAM

Ok, here's my situation. I have an M7VIG Pro motherboard. The book
specifically states "Supports 2 DDR 200/266 MHz (without ECC) devices,
maximum memory size up to 2GB. Both slots can obviously support 1GB modules
each.

I purchased (2) 1GB memory modules. They are labeled as "1GB DDR333 Module
16C". When I insert one of them, and turn on the computer, I get a long beep
(a few seconds), silence, then beep-silence, over and over again until I
turn off the computer. If I put the other one in, the computer seems to boot
up ok, but it's unstable. I can be using the computer when all of a sudden
it just reboots on it's own. If I put both modules in, I get a ton of
registry errors as it boots and the system loads, leading me to having to
shut it down. I've contacted the place I bought them from and they have
offered to replace the modules, but they insist that all memory is tested
prior to shipping so it is unlikely that they are defective.

The only possible cause to this whole thing is my system bus speed. It is
supposed to be capable of running at 133MHz, but when I remove the jumper
that the motherboard says I need to remove, the system won't even boot. With
the jumper on the pins, the system boots, but the bus speed is 100MHz.

Is it possible the bus speed is causing the problem with the DDR memory and
does anyone know what I can do to fix this?
