you might just try running the 667Mhz ram at 533Mhz if there's jumpers 
or a bios setting.  if this works, and htere are fine tuning settings 
for the ram, you might try the original 667 speed only add a clock to 
the CAS precharge (again, ift he BIOS has advanced manual memory timing 
options, some boards do, some don't)

btw, have you tried running memtest86 on these systems ?
