you can do it, even safely, if you use DIMMS that can use 5V, it seems
to me that all those mb's i've seen so far (asus, abit, chaintech,
shuttle and few otherse) will "force" the 5V to DIMM sockets too when
SIMMs are used...

*shrug*

i wouldnt suggest testing it though. =)

general question, your board, does it support over 66MHz buss speeds?
how about running few tests with it? (below)

dd if=/dev/zero of=/dev/null bs=1m count=1000
dd if=/dev/zero of=/dev/null bs=128k count=8000

at least the older Gigabytes were faster than about all other boards
with the 66MHz bus, so if the TX is too...
