Derek;
<p> What I find interesting and surprising is that ALL
the CAS3 DIMMs of the same manufacture were to some degree capable of faster
bus speed than their CAS2 (in some cases dramatically faster, such as the
Mitsubishi brand PC100 DIMMs). If I understand the rating system (and it
seems I don't), CAS2 should be faster. Perhaps this is an issue of motherboard
settings that actually slow down the read/write modes for CAS3 but this
then allows a faster FSB but not necessarily faster data transfers??? Or
have I just screwed up the concept of CAS Latency in general?
<br> And while PC133 were in general a little faster
than their PC100 counterparts, with the PNY it was just the opposite although
not by much. Since my LX boards are sometimes a little picky on memory
(despite being a 66MHz bus), I find these correlations of great interest.
<br>
<p><b> And speaking of these dual Pentium LX boards, I'm still looking
to put some more processors in them. Since a lot of people may have upgraded
their BX boards to faster Pentium 2 chips at 100MHz, does anyone have a
source for some used 300 or 333MHz PII chips? I figure with the faster
Celerons running at 466MHz under $100 and the Via Joshua soon to be released
(this Tuesday???) that a used PII running at 66MHz should be relatively
cheap. And I definitely need inexpensive parts to finish my 9 PCs for the
LINUX cluster.</b>

<br>> Just when I thought I understood how to figure out just how fast

are

be
<br>> more expensive???
<p>A quick look at one of the pages you provided links to shows that the
<br>faster CAS3 RAM is rated at 133MHz, where the CAS2 RAM is only 100MHz.
<br>That explains the speed difference.
<p>As for CAS3 being cheaper, I can only guess that the reason is a lack
of
<br>demand, since most Ix86 chips and clones aren't intended to be run
at
<br>higher than 100MHz, and most people don't overclock.
<p>Cool site though, thanks for the links. :)
