ECC and non ECC will NOT mix.  ECC is used in servers and/or high end machines where 
data integraty is the utmost importance.  Yours has NON ECC memory if it has the 
factory spec modules.

RD RAM is very particular.  When it was relaesed, there were many issues due to it's 
design and speed.  I tried mixing speeds of memory but the machines would fail or 
throw data errors constantly.  Your luck may be better.  With typical SD RAM, adding 
a faster speed ram would simply slow down the faster modules to work with slower 
ones.  For RD RAM, make sure you buy compatible/recommended RAM or you may have problems 
and might be a waste of money if you can't return them.

Win 98/SE/ME has a design limit for the memory it can effectively use.  Adding more 
than 512 meg, won't see much difference if any difference, and you have to add some 
tweaks or you will have out of memory/low resource errors.  Best bet is to stay at 
512 meg of RAM.
