Yes, PC133 will work fine. Mike</blockquote> Not always. The motherboard checks the RAM speed with SPD pin data on the module, and if it can not recognize the code, it will consider it invalid. SOME PC133 may work, other types may not. If I recall the LX also wants to see 16 x 8 RAM chip layout ( in a 128MB module), not more density using less numbers of chips. </body> <body> With our best regards, Maurice W.
