=0D Thanks G Man,=0D I really appreciate all your help with this memory problem.=0D Jo Ann=0D =0D =0D =0D =0D =0D =0D Hi Jo Ann,=0D Both of those modules are identical, except for their rated speed. The=0D 70ns 30pin SIMM is the more desirable of the two. You should understand=0D that if any of the modules already in the mainboard is rated slower than=0D 70ns., the entire collection of modules will run at that slower speed.=0D Conversely, if the modules already in the board are rated faster, the who= le=0D system will still run at the 70ns. that these modules bring to the mix. M= y=0D suggestion, if you can afford it, would be to buy 8 of these modules to=0D guarantee that all of them will be running at their rated speed (and to h= ave=0D them all under a single warrantee).=0D =0D Peace,=0D G Man=20 To unsub or change your email settings: http://www.freelists.org/webpage/pctechtalk To access our Archives: http://groups.yahoo.com/group/PCTechTalk/messages/ http://www.freelists.org/archives/pctechtalk/
