Supported Processors

Express5800/A1160 systems support the following Intel Xeon processor 7400 series (Dunnington) processors:

•Model E7440 (2.4 GHz with 2 x 3-MB L2 cache, 16-MB L3 cache, quad core, 1066 MHz front-side bus)

•Model X7460 (2.66 GHz with 3 x 3-MB L2 cache, 16-MB L3 cache, hex core, 1066 MHz front-side bus)

Check with your sales representative for the availability of a specific processor.

Multicore Processors

Multicore processors contain four or six complete physical processors (cores) in the same integrated circuit. A quad-core processor (four cores) can appear as four logical processors, and a hex-core processor (six cores) can appear as six logical processors.

Extended Memory 64 Technology (EM64T)

The Xeon processors support the Intel EM64T technology. EM64T is an enhancement to the 32-bit Intel architecture. It allows a processor to run 64-bit code and access larger amounts of memory. Processors with Intel EM64T support 64-bit operating systems from Microsoft, SUSE, and Red Hat. Processors running in legacy or 32-bit mode remain fully compatible with existing 32-bit applications and operating systems.

Rules for Mixing Processors

Intel supplies different types, or families, of processors, such as the Intel Xeon processor family. In addition, processors within a given family can have different
