Dual-socket Xeon server board for legacy workloads

The Supermicro E7320 motherboard supports one or two Intel Xeon Nocona processors in Socket P packages. It is aimed at operators maintaining existing infrastructure that requires this specific platform. Builders starting a new deployment should look elsewhere because the architecture is several generations old.

Passive chipset cooling with standard server airflow

The Intel E7320 northbridge and onboard components rely on chassis-directed airflow rather than active heatsinks. Power draw scales with the installed Xeon CPUs and fully populated memory slots. Acoustic output depends entirely on the system fans chosen by the integrator.

Six DDR3 slots and mixed storage interfaces

Six memory sockets accept DDR266 or DDR333 modules up to a total of 24GB. Two SATA 150 ports and an Ultra320 SCSI controller provide period-correct drive connectivity. A single PCI Express x4 slot and three additional expansion slots handle specialised add-in cards. Two USB ports and onboard video complete the rear I/O.

Questions about this item

How do I install a processor into the Socket P (mPGA 604) ZIF socket on this board, and what step is often missed?

Lift the ZIF lever fully, align the 604-pin FC-mPGA4 processor with the socket keying, lower it without force, then close and lock the lever; the step often missed is verifying the lever is completely latched so the CPU makes full contact.

What maintenance or replacement will the onboard Intel video chipset need later?

The integrated Intel video uses system memory and has no separate VRAM or fan; no scheduled maintenance is required, but if the chipset fails the entire motherboard must be replaced.

What limit appears first when the dual Xeon Nocona CPUs run at the 800 MHz front-side bus under sustained load?

The 800 MHz front-side bus shared by both processors becomes the bottleneck before memory bandwidth or the single PCI Express x4 slot saturates.
