Doug Muth writes "There is an article in Wired that talks about a bug in their Pentium III Xeon chips that causes crashes when "when a system is pushed to its highest performance limit", whatever that is supposed to mean. Fortunately, the bug is only present in two specific variations of the chip, the 550 Mhz versions that have either 512 K or 1 Meg of secondary cache. Intel is also working on a bugfix for the problem. " Furthermore, the bug seems to be only present in Intel-brand motherboards, (Sabre). Intel has stopped shipping the board, but not the chip.
