DDR3 modules are developed for   better performance with less power consumption.   The figure illustrates the location of the DDR3 DIMM sockets:   Channel   Sockets   Channel A   Channel B   DIMM_A1   DIMM_B1   P8H61-M LX3 Series   P8H61-M LX3 Series 240-pin DDR3 DIMM sockets   1-12   ASUS P8H61-M LX3 Series   1.7.2   Memory configurations   You may install 1GB, 2GB, 4GB and 8GB unbuffered non-ECC DDR3 DIMMs into the DIMM   sockets.   • You may install varying memory sizes in Channel A and Channel B. The system maps   the total size of the lower-sized channel for the dual-channel configuration. Any excess   memory from the higher-sized channel is then mapped for single-channel operation.   • • Always install DIMMs with the same CAS latency. For optimum compatibility, we   recommend that you obtain memory modules from the same vendor.   Due to the memory address limitation on 32-bit Windows® OS, when you install 4GB   or more memory on the motherboard, the actual usable memory for the OS can be   about 3GB or less. For effective use of memory, we recommend that you do any of the   following:   - Use a maximum of 3GB system memory if you are using a 32-bit Windows® OS.   - Install a 64-bit Windows® OS when you want to install 4GB or more on the   motherboard.   • • This motherboard does not support DIMMs made up of 512Mb (64MB) chips or less.   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 2.4 Ai Tweaker menu for manual memory frequency   adjustment.   • For system stability, use a more efficient memory cooling system to support a full   memory load (2 DIMMs) or overclocking condition.   P8H61-M LX3 Series Motherboard Qualified Vendors Lists (QVL)   DDR3-1066 MHz capability   DIMM socket   support (Optional)   Vendors   Part No.   Size   SS/DS Chip Brand Chip NO.   Timing   Voltage   A*   B*   Crucial   CT12864BA1067.8FF   EBJ10UE8EDF0-AE-F   1GB   1GB   SS   SS   Micron   9GF22D9KPT   7 - - • • 1.35V(low   voltage)   ELPIDA   ELPIDA   J1108EDSE-DJ-F   • • • • 1.35V(low   voltage)   ELPIDA   EBJ21UE8EDF0-AE-F   2GB   DS   ELPIDA   J1108EDSE-DJ-F   - KINGSTON KVR1066D3N7/2G   KINGSTON KVR1066D3N7/4G   2GB   4GB   DS   DS   DS   ELPIDA   Hynix   J1108BDSE-DJ-F   H5TQ2G83AFR   9HF22D9KPT   7 7 7 1.5V   1.5V   - • • • • • • Micron   MT16JTF25664AZ-1G1F1 2GB   Micron   Chapter 1: Product introduction   1-13   DDR3-1333 MHz capability   DIMM socket   support   (Optional)   SS/ Chip   Vendors   Part No.   Size   Chip NO.   Timing Voltage   DS   Brand   A*   • B*   • A-DATA   A-DATA   A-DATA   Apacer   AM2U139C2P1   2GB   4GB   8GB   2GB   SS   DS   DS   DS   ADATA   3CCD-1509A EL1127T   - - - - - - - - AM2U139C4P2   ADATA   3CCD-1509A EL1127T   • • SU3U1333W8G9-B   AU02GFA33C9NBGC   TR3X3G1333C9 G   TW3X4G1333C9D G   CMX4GX3M1A1333C9   BL25664BN1337.16FF (XMP)   ELPIDA   J4208BASE-DJ-F   • • Apacer   AM5D5808APQSBG   • • CORSAIR   CORSAIR   CORSAIR   Crucial   3GB(3 x 1GB) SS   4GB(2 x 2GB) DS   - - - - - - - - 9-9-9-24 1.50V   9-9-9-24 1.50V   9-9-9-24 1.50V   7-7-7-24 1.65V   • • • • 4GB   DS   • • 6GB(3 x 2GB) DS   • • 1.35V(low   voltage)   ELPIDA   ELPIDA   EBJ10UE8EDF0-DJ-F   EBJ21UE8EDF0-DJ-F   1GB   SS   ELPIDA   ELPIDA   J1108EDSE-DJ-F   J1108EDSE-DJ-F   - • • • • 1.35V(low   voltage)   2GB   1GB   DS   SS   - - G.SKILL   G.SKILL   G.SKILL   F3-10600CL8D-2GBHK(XMP)   F3-10600CL9D-2GBNQ   G.SKILL   - - - - • • • • • • 2GB(2 x 1GB) SS   - - 9-9-9-24 1.5V   F3-10666CL8D-4GBECO(XMP) 4GB(2 x 2GB) DS   8-8-8-24 XMP 1.35V   1.3V(low   9-9-9-24   GEIL   GG34GB1333C9DC   4GB(2 x 2GB) DS   4GB(2 x 2GB) DS   GEIL   - GL1L128M88BA12N   - • • voltage)   GEIL   GVP34GB1333C7DC   FLFD45F-B8KL9 NAES   FLFF65F-C8KL9 NEES   FLFF65F-C8KM9 NEES   7-7-7-24 1.5V   • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • KINGMAX   KINGMAX   KINGMAX   1GB   4GB   4GB   2GB   SS   DS   DS   SS   KINGMAX KKB8FNWBFGNX-27A   KINGMAX KFC8FNLXF-DXX-15A   KINGMAX KFC8FNMXF-BXX-15A   - - - - - - KINGSTON KVR1333D3N9/2G(low profile)   Hynix   - H5TQ2G83AFRH9C   - 9 9 - - KINGSTON KHX1333C9D3UK2/4GX(XMP) 4GB(2 x 2GB) DS   XMP 1.25V   KINGSTON KVR1333D3N9/4G(low profile)   4GB   4GB   2GB   4GB   4GB   1GB   4GB   DS   DS   SS   DS   DS   SS   DS   ELPIDA   KTC   J2108BCSE-DJ-F   D2568JENCNGD9U   IJM22 D9PFJ   1.5V   KINGSTON KVR1333D3N9/4G   - 1.5V   Micron   Micron   NANYA   MT8JTF25664AZ-1G4M1   MT16JTF51264AZ-1G4D1   NT4GC64B8HG0NF-CG   MICRON   Micron   NANYA   Hynix   - - - - - - OLD22D9LGK   NT5CB256M8GN-CG   H5TQ1G83TFR   - - Super Talent W1333UA1GH   Super Talent W1333UB4GS   Super Talent W1333UX6GM   9 - SAMSUNG K4B2G0846C   6GB(3x 2GB) DS   Micron   Micron   0BF27D9KPT   0YD77D9LGK   9-9-9-24 1.5V   Transcend   Transcend   JM1333KLN-2G   JM1333KLU-2G   2GB   2GB   SS   DS   - - - - Transcend TK243PDF3   SS: Single-sided / DS: Double-sided   DIMM support:   • A*: Supports one module inserted into either slot as single-channel memory   configuration.   • B*: Supports one pair of modules inserted into both the blue slots as one pair of dual-   channel memory configuration.   1-14   ASUS P8H61-M LX3 Series   1.7.3   Installing a DIMM   Unplug the power supply before adding or removing DIMMs or other system components.   Failure to do so can cause severe damage to both the motherboard and the components.   2 1.   2.   Press the retaining clips outward to   unlock a DIMM socket.   DIMM notch   Align a DIMM on the socket such that   the notch on the DIMM matches the   DIMM slot key on the socket.   1 1 DIMM slot key   Unlocked retaining clip   A DIMM is keyed with a notch so that it fits in only one direction.

Failure to do so may   cause you physical injury and damage motherboard components.   1.8.1   Installing an expansion card   To install an expansion card:   1.   Before installing the expansion card, read the documentation that came with it and   make the necessary hardware settings for the card.   2.   3.   Remove the system unit cover (if your motherboard is already installed in a chassis).   Remove the bracket opposite the slot that you intend to use. Keep the screw for later   use.   4.   Align the card connector with the slot and press firmly until the card is completely   seated on the slot.   5.   6.   Secure the card to the chassis with the screw you removed earlier.   Replace the system cover.   1.8.2   Configuring an expansion card   After installing the expansion card, configure it by adjusting the software settings.   1.   Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for   information on BIOS setup.   2.   3.   Assign an IRQ to the card.   Install the software drivers for the expansion card.   When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that   the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI   groups, making the system unstable and the card inoperable.   1.8.3   PCI Express x1 slot   This motherboard supports PCI Express x1 network cards, SCSI cards, and other cards that   comply with the PCI Express specifications.   1.8.4   PCI Express x16 slot   This motherboard has a PCI Express 2.0 x16 slot that supports PCI Express x16 2.0 graphic   cards complying with the PCI Express specifications.   1-16   ASUS P8H61-M LX3 Series   IRQ assignments for this motherboard   A – – B – – C – – D – – E F – – G – H – – Intel PCH SATA controller #0   Intel PCH SATA controller #1   shared   shared   – Realtek 8111F controller   PCIE x16   – shared   – shared   – – – – – – – – – – – – – – – – – – – PCIE x1   shared   1.9   Jumpers   Clear RTC RAM (3-pin CLRTC)   This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can   clear the CMOS memory of date, time, and system setup parameters by erasing   the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in   CMOS, which include system setup information such as system passwords.   CLRTC   1 2 2 3 P8H61-M LX3 Series   Normal   Clear RTC   (Default)   P8H61-M LX3 Series Clear RTC RAM   To erase the RTC RAM:   1. Turn OFF the computer and unplug the power cord.   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. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter   data.   Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default   position. Removing the cap will cause system boot failure!   • • If the steps above do not help, remove the onboard battery and move the jumper again   to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.   You do not need to clear the RTC when the system hangs due to overclocking. For   system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature. Shut   down and reboot the system, then the BIOS automatically resets parameter settings to   default values.   Chapter 1: Product introduction   1-17   1.10   Connectors   1.10.1   Rear panel connectors   1 2 3 4   9 8 7 6 5 1.   2.   PS/2 Mouse port.
