The setup of the configuration jumpers on the SHB is described below.
* indicates the default value of each jumper.
NOTE: For two-position jumpers (3-post), "RIGHT" is toward the bracket end of the board; "LEFT" is toward the processor(s).

JU8 Password Clear
Install for one power-up cycle to reset the password to the default (null password).
Remove for normal operation. *

JU10/JU11 System Flash ROM Operational Modes
The Flash ROM has two programmable sections: the Boot Block for "flashing" in the BIOS and the Main Block for the executable BIOS and PnP parameters. Normally only the Main Block is updated when a new BIOS is flashed into the system.

	JU10	JU11
All Blocks Write Enabled Boot Block Write Protected Block 2-16 Write Protected	Remove * Install Remove	Remove * Remove Install

JU12 CMOS Clear
Install on the RIGHT to operate.*
Install on the LEFT to clear.
NOTE: To clear the CMOS, power down the system and install the jumper on the RIGHT. Wait for at least two seconds, move the jumper back to the LEFT and turn the power on. When AMIBIOS displays the "CMOS Settings Wrong" message, press F1 to go into the BIOS Setup Utility, where you may reenter your desired BIOS settings, load optimal defaults or load failsafe defaults.

NOTE:
Pin 1 on the connectors is indicated by the square pad on the PCB.

The four-channel Double Data Rate (DDR2) memory interface on the MCXT and MCXI SHBs supports up to 16GB of Fully Buffered DIMM (FB-DIMM) memory; the MCXT-E and MCXI-E models support up to 32GB of FB-DIMM memory.
FB-DIMMs have “Advanced Memory Buffer” chips that provide enhanced signal integrity and improved error detection that help reduce soft memory errors. FB-DIMM memory technology improves overall system reliability by extending the current ECC capability to include protection of command and address data. FD-DIMMs feature automatic retries when a memory error is detected, which results in uninterrupted system operation in the event of transient errors.
An MCX-series SHB uses industry standard 72-bit wide ECC gold finger FB-DIMM memory modules in four (MCXT/MCXI) or eight (MCXT-E/MCXI-E) 240-pin sockets. The FB-DIMMs must be PC2-4200 or PC2-5300 (DDR2-533 or DDR2-667) and comply with the JEDEC Rev. 2.0 specifications.
The following dual-rank FB-DIMM sizes are supported:

FB-DIMM Size	DIMM Type	ECC
512MB	Registered	64M x 72
1GB	Registered	128M x 72
2GB	Registered	256M x 72
4GB	Registered	512M x 72

A minimum of one 512MB FB-DIMM is required and must be populated in DIMM socket BK0A.
NOTE: With the bracket end of the board to the right, the four FB-DIMM sockets available on the MCXT and MCXI SHBs are numbered BK0A, BK1A, BK0B and BK1B, from top to bottom. On the extended-memory MCXT-E and MCXI-E SHBs, there are an additional four FB-DIMM sockets. The upper sockets are BK2A and BK2B, from left to right, and the lower sockets are BK3A and BK3B. These socket definitions are illustrated in the board layouts. All memory modules must have gold contacts.
NOTE: To maximize memory interface speed and bandwidth, and to take full advantage of the four-channel memory interface of the SHB’s memory controller hub, the FB-DIMMs in socket banks 0A and 1A must be identical with respect to manufacturing, speed, timing and organization. Likewise, FB-DIMMs used in sockets 0B and 1B must be identical. FB-DIMMs in socket banks contained within the same memory channel, i.e., 0A and 2A do not have to be identical.
A minimum of one 512MB FB-DIMM is required and must be populated in DIMM socket BK0A. When using more that one FB-DIMM, you must populate the memory sockets in multiples of two in order to maximize the speed and performance of the memory interface. The following table explains the DDR2 FB-DIMM population rules:

FB-DIMM POPULATION CONFIGURATION	FB-DIMM Sockets (MCXT, MCXE)				FB-DIMM Sockets (MCXT-E, MCXI-E)
FB-DIMM POPULATION CONFIGURATION	BANK 0A	BANK 1A	BANK 0B	BANK 1B	BANK 2A	BANK 2B	BANK 3A	BANK 3B
Single Module	FB-DIMM	Empty	Empty	Empty	Empty	Empty	Empty	Empty
Two Modules	FB-DIMM	FB-DIMM	Empty	Empty	Empty	Empty	Empty	Empty
Four Modules	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	Empty	Empty	Empty	Empty
Six Modules	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	Empty	Empty
Eight Module	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM	FB-DIMM
