Hi, I just wanted to comment on the following as I have been told differently. I was under the impression that this is not the case. I was told by several different people that the motherboard would default to the lowest throughput, in this case 100mhz. No trees were destroyed in sending this message; however, a large number of electrons were terribly inconvenienced. -----Original Message----- From: speakup-bounces@xxxxxxxxxxxxxx [mailto:speakup-bounces at braille.uwo.ca] On Behalf Of Allan Shaw Sent: Monday, March 22, 2004 9:40 PM To: Speakup is a screen review system for Linux. Subject: Re: ram question ... If I've read your question correctly, you have 3 ram modules, a256 mb 133 and 2 128 mb 100 chips. well you can't mix chip speeds. Your motherboard will either support 100 mhz or 133 mhz chips but not both.
