ew Microprocessor Options
The Dell Latitude LM is now available with a
166-megahertz (MHz) or 133-MHz Intel
®
Pentium
®
microprocessor with MMX
™
technology.
Current application programs not designed specifically
for MMX technology should have a small improvement
in performance when run on a system with a Pentium
microprocessor with MMX technology. Software written
specifically to take advantage of MMX technology
(which will be labeled “Designed for Intel MMX”) will
have a greater improvement in performance, depending
on the type of application program.
The Pentium microprocessor with MMX technology has
twice the internal cache memory (32 kilobytes [KB]) as
the standard Pentium microprocessor.
To see the technical specifications of the new micro-
processors, search on “microprocessor specifications” in
the online System User’s Guide. The online guide is in
the Dell Accessories folder or program group.
N
ew Memory Module Support
The Dell Latitude LM now supports 32-megabyte (MB)
memory modules. With the 8 MB of standard non-
removable memory on the system board and two 4-MB
memory modules standard with every Latitude LM, the
computer now supports a maximum of 72 MB of system
memory. The following memory module combinations
are possible:
•
24 MB — Install two 8-MB memory modules.
•
40 MB — Install two 16-MB memory modules.
•
72 MB — Install two 32-MB memory modules.
N
ew Memory Specifications
The Dell Latitude LM now supports extended-data out
(EDO) memory. EDO memory technology improves per-
formance over fast-page-mode technology by using a
shorter page-mode cycle time while accessing data
within a single page of memory. See the following table
for the updated memory specifications.
