Intel® Server Board SE7505VB2
Functional Architecture
3.2.1.1 DDR
Configurations
The DDR interface supports up to 8 GB of main memory and supports single- and double-
density DIMMs. The DDR can be any industry-standard DDR. The following table shows the
DDR DIMM technology supported.

Memory Controller Hub (MCH)
The MCH is a 1005-ball FC-BGA device and uses the proven components of previous
generations like the Intel Xeon processor bus interface unit, the hub interface unit, and the DDR
memory interface unit. In addition, the MCH incorporates a hub interface (HI) .
The HI interface
allows the MCH to directly interface with the P64H2. The MCH also increases the main memory
interface bandwidth and maximum memory configuration with a 144-bit wide memory interface.
The MCH integrates the following main functions:
An integrated high performance main memory subsystem.
An HI 2.0 bus which provides an interface to the P64H2
An HI 1.5 bus which provides an interface to the ICH4
AGP pro slot: Video controller with 3D/2D graphics accelerator
Other features provided by the MCH include the following:
Full support of ECC on the processor bus
Full support of Intel x4 SDDC on the memory interface with x4 DIMMs
Twelve deep in-order queue, two deep defer queue
Full support of registered DDR266 ECC DIMMs.
Support for 2 GB DDR memory modules
Memory scrubbing
