Rearranged text, forgot to add a 'new line'.

2018-11-15T17:11:58Z

Re-arranged text.

2018-11-14T06:32:36Z

Re-arranged information, should be more or less readable now.

2018-11-14T00:33:28Z

Undo revision 58920 by Bugmenot2 (talk) This information is useful. You butchered a link which was not dead.

2018-11-13T15:01:40Z

Added the datasheet for this northbridge.

2018-11-13T14:22:22Z

Forgot to add the footnotes, added.

2018-11-13T14:10:30Z

Added some memory modules that are supported by this northbridge. Compressed some notes into a footnote.

2008-12-28T22:44:09Z

Minor grammar changes.

 == Maximum Memory ==
 Maximum addressable memory for this Northbridge is 1GB (using four 256MB DIMMs).<br>
-No ThinkPad has more then 2 DIMM slots, so are in theory limited to 512MB (with the exception of the 600X, which has an additional 64MB soldered to the systemboard, and can oficially support 64+256+256=576MB). Actual supported memory can be significantly less due to BIOS limits or available DIMM slots.
