I recently constructed a system based on the S3420GPLX motherboard and encountered a couple problems relating to the PCI & PCI-E slots. First, the system configuration:
Current System Configuration:
Intel S3420GPLX Motherboard
Intel Xeon X3470 Processor
Intel SC5650UPNA Pedestal Server Case
Kingston KVR1066D3Q8R7SK2/16GI Memory Kit (x2)
Point Grey FWB-PCIE-02 Dual Bus 1394b PCI-E Card (x5)
HIS H545H512P Radeon HD 5450 PCI Video Card
Western Digital WD1001FALS 1TB Hard Drive
Slot 1 (32-bit PCI): See Problem #1, HIS H545H512P
Slot 2 (PCI-E Gen1 x1): Point Grey FWB-PCIE-02
Slot 3 (PCI-E Gen1 x4): Point Grey FWB-PCIE-02
Slot 4 (PCI-E Gen2 x4): Point Grey FWB-PCIE-02
Slot 5 (PCI-E Gen2 x8): See Problem #2, Point Grey FWB-PCIE-02
Slot 6 (PCI-E Gen2 x8): Point Grey FWB-PCIE-02
DIMM B1: Populated, 8GB
DIMM B2: Populated, 8GB
DIMM B3: Empty
DIMM A1: Populated, 8GB
DIMM A2: Populated, 8GB
DIMM A3: Empty
System BIOS: R0048 (latest version)
BMC Firmware: v01.23 (latest version)
FRUSDR Utility: 18 (latest version)
Background: The system is intended to interface with up to 10 high-resolution, high-bandwidth IEEE1394b video cameras from Point Grey Research and perform real-time image analysis. Each video camera is capable of fully utilizing an entire 800Mbps IEEE1394b bus, hence the use of multiple dual-bus IEEE1394b PCI-E adapters. A PCI video card was added due to the poor general performance and limited resolution of the onboard video solution.
Problem #1: The motherboard will not POST with the HIS H545H512P PCI video card installed. The startup process halts before the display is enabled, preventing access to the BIOS and preventing OS boot. The diagnostic LED code is 0x50 “Enumerating PCI Buses”. This happens regardless of whether the monitor is connected to the on-board video or the PCI video card. Removing the PCI video card allows the computer to boot normally; however, the performance of the onboard video is inadequate for the intended application.
This particular PCI video card has be successfully tested in another machine without issue. I have tried disabling the onboard video in the BIOS, as well trying the dual monitor video BIOS option, without success. I also tried using a higher wattage power supply in case the standard 400W was insufficient; this did not work either. Removing all other add-on cards and peripherals does not change anything. Are there any known compatibility issues with the S3420GPLX motherboard and PCI video cards? What are my options / potential workarounds for this issue? Please note that a PCI-E video card cannot be used since all PCI-E slots will eventually be occupied with dual-bus IEEE1394b adapters.
Problem #2: Slot 5 (PCI-E Gen2 x8) does not appear to be functional on this motherboard and will not detect the installed Point Grey FWB-PCIE-02 card. The system still boots normally in this case, the card is simply not detected. The other four PCI-E slots appear to function normally and will properly detect the Point Grey FWB-PCIE-02 cards. All FWB-PCIE-02 cards have been tested and verified to work correctly in another system. Are there any BIOS settings or configuration changes that could be made to enable use of all 5 PCI-E slots? Is it possible/likely that the motherboard is defective?
