A recently discovered flaw inside two Xeon processors is holding up some of the highest-performing Intel-based systems yet.
Less than a month after shipping the first eight-processor systems, many server makers are halting production due to a problem the 550MHz Pentium Xeon chip.
The flaw affects processors with either 512 kB or 1MB of secondary cache memory, when used in an eight-way server with a Saber motherboard. The voltage from the processors can exceed the recommended voltage limits for the Intel-designed motherboard, causing a “blue screen” system crash.
The bug does not occur with the 550MHz Xeons with 2MB of cache, or when the 512 kB or 1MB versions are used with other motherboards.
