Working with memory
Your xSeries 330 supports 256 MB, 512 MB, and 1 GB 133 MHz, ECC, SDRAM,
registered x4 (Chipkill) DIMMs.
Note: Chipkill Memory protection is disabled if any DIMM in your server is not an x4
DIMM.
See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory
modules for use with your server.
About MXT memory
The IBM MXT technology on your server expands the capacity of the DIMMs installed
in your server. Depending on the applications running and the load on the system,
MXT can expand your server usable memory up to nearly twice the amount of
physical memory.
Important: To activate the MXT technology on your server:
• An MXT device driver supporting your operating system might be required. The
IBM MXT device driver for Microsoft® Windows® 2000 is available on the
ServerGuide CD. The Red Hat Linux® 7.2 operating system includes MXT
support natively, and does not need a separate device driver.
• The MXT Aware OS setting must be Enabled (the default value) and the Report
Real setting must be Disabled (the default value) in Core Chipset Control in the
Advanced Setup section of the Configuration/Setup utility program.
How you determine whether MXT is activated depends on your operating system. In
Windows 2000, for example, you can look at the memory information in the Task
Manager: under
Physical memory on the Performance page, if the amount of
memory in Total is greater than the amount of physical memory you have installed in
your server, then MXT is activated.
The MXT device driver for Windows 2000 is located in the self-extracting file
\images\en\setupmxt.exe on the ServerGuide
Setup and Installation CD. Use the
ServerGuide CDs to install the MXT device driver (see “Using the ServerGuide CDs”
on page 27 for more information), or download and install the latest MXT driver from
http://www.ibm.com/pc/support/ on the World Wide Web.
