Step 3 Install Additional Voltage Regulator

Two Voltage Regulator Modules (VRMs) are shipped with every MegaDual motherboard.
Each installed CPU requires its own VRM. Even if you use only one CPU, you can install
both VRMs on the motherboard.

Caution

Do not power up the MegaDual board if there is a CPU
installed without a corresponding VRM.
