! MVP3 (super socket 7, K6-2) chipset motherboards
Some motherboards using this older chipset have small L2 caches, meaning if you have too much RAM then performance will become very slow when it is in use. The boards with 512KB can only cache 128MB, and the boards with 1MB can only cache 256MB, so if you are using ram above that limit then all memory reads/writes will take a lot longer.
''Theres reference for mother boards that do this that you can turn the uncached memory into very high speed swap space. This means that as long as your working set is inside your cachable memory then your computer is very very fast. Anyone know if you can convince Linux to use swap in preference to disk I/O? (ie: swap out disk cache onto a faster medium such as this 'high' memory?) -- PerryLorier''

+! Power Supply
+If you want to blow up your power supply unit, simply forget to plug the connector into your motherboard after changing it, then plug the power into the wall. (This was a 230W Hyena brand [PSU] by the way). Update - it appears a capacitor blew its cover right off. See [pretty picture|http://www.wlug.org.nz/archive/images/psu.jpg?]
