Compaq and Dell are the first OEMs to break the Xeon log jam with their announcements that they are now shipping Xeon- powered servers.
Dell shipped its dual-Xeon PowerEdge 6300 and Compaq shipped its first ProLiant 6000, code-named Javelin, to Microsoft.
While Compaq and Dell may be the first, they will almost certainly be leading a charge.
An Intel representative said the company has been shipping "screened processors" to OEMs for over a week.
Although most server manufacturers announced availability of Xeon servers in late June, a problem in the processor chip set was uncovered, delaying shipments.
The error was in the circuitry that checks Level 2 cache memory, coordinating CPUs accessing the same data in multiprocessor systems.
