DIMM Vendors - SDRAM ECC DIMMs
Error checking and correcting (ECC) memory detects multiple-bit errors and corrects single-bit errors. When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the Setup program. The BIOS automatically detects if ECC memory is installed and provides the Setup option for selecting ECC mode. If any non-ECC memory is installed, the Setup option for ECC mode does not appear.

The following table describes the effect of using Setup to put each memory type in each supported mode. Whenever ECC mode is selected in Setup, some performance loss occurs.

• What is in a "boxed" Pentium II processor?
  The boxed Pentium II processor includes a Pentium II processor with an active fan heatsink attached. It also includes a fan cable and the fan heatsink supports that are used to mount the processor to the motherboard.
  
  

• What hardware is needed to integrate an Intel® Celeron® processor with the Intel LM440LX Motherboard?
  The correct retention mechanism and heatsink supports are required to integrate the Intel Celeron processor on the Intel LM440LX Motherboard.

  Retention Mechanism:
  To integrate an Intel Celeron processor on the motherboard, a Single Edge Processor Package (SEPP) retention mechanism is used. The retention mechanism must be compatible with metal fasteners.

  The motherboard has a Retention Mechanism Attach Mount (RMAM) with metal fasteners. The holes in the motherboard are .140" (.35560 cm) and are only compatible with the metal fastener SEPP retention mechanism. Plastic Push Pin fasteners made for .159" (.40386 cm) motherboard holes will not work with the holes on the motherboard.

  Heatsink:
  There are two versions of heatsink supports depending on whether the heatsink solution is passive or active (with fan). Passive heatsink supports are pre-installed on the motherboard. The motherboard also requires a heatsink support top bar. If you would like to use an active heatsink solution, you will need to remove the bottom passive heatsink support from the motherboard.

  • Retention Mechanism: A Retention Mechanism (RM) is needed to help secure the processor to the motherboard.
  • Heatsink Supports: There are two versions of heatsink supports depending on whether the heatsink solution is passive or active (with fan).
    • Passive heatsink supports are pre-installed on the Intel LM440LX Motherboard. The Intel LM440LX Motherboard also requires a heatsink support top bar.
    • Active heatsink supports are included with the boxed Pentium II processor. If you would like to use an active heatsink solution, you will need to remove the bottom passive heatsink support from the Intel LM440LX Motherboard.

  For a list of vendors supplying retention mechanisms and passive heatsink supports, visit the Pentium II processor support components web site.
  

• How do I remove the bottom passive heat sink support from the Intel LM440LX Motherboard without damaging it, or the motherboard?
  After removing the oval headed plastic pins, the support is gently rocked back and forth until it comes off the board. A special tool (part number 58982-01) is available through Dexter Design in the United States (503) 648-7000 which will facilitate the safe removal.
  

  Refer to the LM440LX Motherboard technical product specification.

• What does the new 82440LX AGPset support?
  The 82440LX AGPset introduces Accelerated Graphics Port (AGP) technology, which streamlines the flow of data between the processor, graphics accelerator and system memory, delivering a new level of rich media to the PC. The 440LX AGPset also implements Ultra DMA/33 capability which doubles bandwidth to all IDE devices including hard disk drives and CD ROMS; and SDRAM support for increased memory bandwidth and improved overall system performance.
  

• What is the Accelerated Graphics Port (AGP)?
  AGP is a dedicated graphics bus with higher bandwidth that allows texturing from main memory. By providing high-bandwidth access to memory, AGP enables a new level of sophisticated graphics allowing software developers to create richer, more inviting 3D environments with higher resolutions than ever before
  

• What is Ultra DMA/33?
  Ultra DMA/33 is a faster hard drive protocol that improves disk I/O throughput to up to 33MB/second. Both edges of the IDE strobe are read to obtain double the speed across the cable.
  

• Do I need a special hard drive to take advantage of Ultra DMA/33?
  Yes. The AGPset will still function with mode 3 and mode 4 disks, but to take advantage of Ultra DMA/33 you will need to request an Ultra DMA/33 drive from your hard drive vendor.
  

• What kind of memory does the Intel LM440LX Motherboard support?
  Intel LM440LX Motherboard only supports Synchronous DRAM (SDRAM) DIMMs. SDRAM DIMMs should conform to version 1.0 of the 4 clock, 3.3 volt synchronous DRAM specification and must have the Serial Presence Detect EPROM area programmed. The Intel LM440LX Motherboard does not support EDO memory. Refer to the list of tested memory DIMMs.
  

• Should I use DIMMs with tin- or gold-plated contacts on the Intel LM440LX Motherboard?
  Only gold-plated DIMMs should be used with the Intel LM440LX Motherboard. Do NOT use DIMMs with tin-plated contacts with this board.
  

• What is hardware monitoring?
  Intel LM440LX Motherboard has a component on the motherboard that monitors the temperature, fans, and voltages in the system. System readings and alerts are available to management software, if present, such as the LANDesk* Client Manager.
  

• Do I need a special power supply for the Intel LM440LX Motherboard?
  The Intel LM440LX Motherboard requires a 3.3 volt power supply that complies with the NLX 1.2 specification. See the NLX Power Supply Recommendation V1.1.
  

• Why isn't there a power connector on the Intel LM440LX Motherboard?
  With the NLX form factor, the power connector has been moved off the motherboard and onto the riser. This allows the easy removal of the "dockable" motherboard from the chassis. In fact, all power and data cables have been moved to the riser. Thus, an NLX 1.2 compliant riser is necessary to power the motherboard.
  

• Where can I purchase an NLX compliant riser?
  A current list of suppliers is available on the NLX web Site, http://www.teleport.com/~nlx and is updated regularly. Keep in mind that the riser must be able to fit in the selected chassis which in many cases already has a riser built specifically for that chassis. It is the intent of chassis vendors to supply the riser that fits with their chassis and offer several design choices. See vendor-specific information.
  

• How can the onboard audio be disabled?
  The onboard audio can be disabled using the BIOS Setup Utility. Select the Advanced menu, then the Peripheral Configuration screen. The menu will offer options to enable or disable the audio if it is present on the motherboard. Refer the Technical Product Specification (TPS) for other setup options.
  

• Does Intel LM440LX Motherboard support 1394 (Firewire*)?
  No, support for IEEE 1394 is not available on the Intel LM440LX Motherboard.
  

• How many I/O slots do Intel LM440LX Motherboards and systems have?
  With NLX, I/O slots are located on the riser not on the motherboard. Therefore, the Intel LM440LX Motherboard has no I/O slots on board. Slots for ISA/PCI are a function of the riser card design. For a list of vendors, please refer to the NLX web site.  Note:  This link will take you off of the Intel website.  Intel is not responsible for the content on this site.
  

• Will Intel sell NLX riser cards to go with NLX Motherboards?
  No. Riser cards are chassis-dependent. The customer will need to source their own chassis and riser card. A list of NLX vendors is available on the NLX web site.
  

• What do I require to power-up my Intel LM440LX Motherboard?
  The power supply chosen must meet the NLX 1.2 specification. A momentary switch should be used for the power on/off switch and the sleep/resume switch. An NLX compliant riser card, and the correct memory and processor are also required. Please refer to the Technical Product Specification for more details.
  

• I am getting beep code 1-3-3-1 and my motherboard does not boot or show any video. What does this mean?
  This beep code indicates that there was a problem during DRAM memory device detection. This is probably because the Serial Presence Detect (SPD) EEPROM data on the DIMM is either missing or is not programmed correctly. Replace the DIMMs with ones from the tested memory list.
  

• What is included in the RPD augmented 10 pack?
  Included with the 10 motherboards is a quick start guide and 10 each of the following: CD-ROM (which includes LANDesk* Client Manager, LANDesk Virus Protect, drivers, and product guide), floppy cable, IDE cable, I/O shield, passive heatsink support kit, processor retention mechanism, and configuration label stickers.
