2. Upgradeability

2-1. Processor

User can upgrade CPU

- Pentium 4 / Pentium-D / Core2Due / Celeron / Conroe-L

2-2. Memory

The Burberry motherboard has two Dual Inline Memory Module (DIMM), minimum 256MB to maximum 2GB memory size. The BIOS detects the memory type, size, and speed through SMBUS interface between the core chipset and DIMM module automatically.

The motherboard supports the following memory features

•

Maximum memory size : 2GB

•

Directly supports one or two channels of memory (each channel consisting of 64 data lines)

•

Supports DDR2 400, DDR2 533, and DDR2 667

•

Available bandwidth up to 5.3 GB/s (DDR2 667) for single-channel mode or dual-channel asymmetric mode and 10.7 GB/s (DDR2 667) in dual-channel Interleaved mode.

•

Supports DDR2 memory DIMM frequencies of 400MHz, 533MHz, and 667MHz. The speed used in all channels is the speed of the slowest DIMM in the system.

•

Supports 256-Mb, 512Mb, and 1-Gb DDR2 technologies for x8 and x16 devices.

•

Supports four banks for all DDR2 devices up to 512-Mbit density

•

DDR2-667 4-4-4 is Not supported

•

Supports only unbuffered DIMMs

•

SPD (Serial Presence Detect) scheme for DIMM detection support

•

Supports configurations defined in the JEDEC DDR DIMM specification only

2-3 BIOS

θ

Flash memory (FWH) organization

The Burberry motherboard uses a AMI BIOS, which is stored in the flash memory and can be upgraded using a disk-based or Windows-based program. An old version of the BIOS can be updated to the newer version using the Flash Memory Update utility in a floppy diskette or HDD.
