<div dir="ltr">yeah? I couldn't find any 2 gig memory chips so I got the two 1 gig chips. As for the speed of the chips I hope what I got is okay. The chips in now say 800 Mhz..... oops! the chips I bought are 533 Mhz :( What will the two different speeds do? Should I buy two more of the 533 Mhz?</div><div class="gmail_extra"><br clear="all"><div>:-)~MIKE~(-:</div>

There is a tradeoff here – if you have enough memory to keep your computer from swapping/paging/whatever-ing to and from disk then speed of ram matters. If, however, you don’t have enough memory to keep the majority of ‘active’ programs in memory so you don’t need to go read them from the disk before they can run – well, then faster is better for those things in memory, but as soon as the disk transfer gets slower than the execution speed your faster ram is useless. Or at least doesn’t help as much as it should. IMHO, of course ;-)<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><u></u> <u></u></span></p><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> <a href="mailto:plug-discuss-bounces@lists.phxlinux.org" target="_blank">plug-discuss-bounces@lists.phxlinux.org</a> [mailto:<a href="mailto:plug-discuss-bounces@lists.phxlinux.org" target="_blank">plug-discuss-bounces@lists.phxlinux.org</a>] <b>On Behalf Of </b>Mark Phillips<br><b>Sent:</b> Thursday, October 09, 2014 7:36 AM<br><b>To:</b> Main PLUG discussion list<br><b>Subject:</b> Re: memory<u></u><u></u></span></p><div><div class="h5"><p class="MsoNormal"><u></u> <u></u></p><div><div><p class="MsoNormal" style="margin-bottom:12.0pt">Michael,<u></u><u></u></p></div><div><p class="MsoNormal" style="margin-bottom:12.0pt">It seems the max memory is 4GB for that system - 4 banks of 1 GB sticks.<br>RAM memory Capacity - 4 GB <br>Memory Type - DDR2 SDRAM - DIMM 240-pin<br>Data Integrity Check - Non-ECC<br>Speed - 667 MHz ( PC2-5300 )<br>Features - Dual rank , unbuffered<u></u><u></u></p></div><div><p class="MsoNormal">You already have 2 1GB sticks in the machines - what speed are they?
