1.4 System memory 1.4.1 Overview This motherboard comes with two Double Data Rate 3 (DDR3) Dual Inline Memory Module (DIMM) sockets. A DDR3 module is notched differently from a DDR or DDR2 module. DO NOT install a DDR or DDR2 memory module to the DDR3 slot. DIMM_A1 DIMM_B1 According to Intel® CPU spec, DIMM voltage below 1.65V is recommended to protect the CPU. Channel Channel A Channel B Sockets DIMM_A1 DIMM_B1 H81M2 H81M2 240-pin DDR3 DIMM sockets 1.4.
1.4.3 • The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, refer to section 2.5 Ai Tweaker menu for manual memory frequency adjustment.
Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force. 2 1 1 2. Remove the DIMM from the socket. 1.5 DIMM notch Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.
1.5.3 PCI Express 2.0 x1 slots This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that comply with the PCI Express specifications. 1.5.4 PCI Express x16 slot This motherboard has a PCI Express x16 slot that supports PCI Express x16 graphic cards complying with the PCI Express specifications. 1.5.3 PCI slots The PCI slot supports cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2. 3. Plug the power cord and turn ON the computer. 4.
