Firewire 400 (1394a) misbehaving - causes reboot

[crashmeister]

I need suggestions to fix the following:

I have a Gigabyte X48-DS4 running a Q9450 at 3.2 GHz (400x8).

I have a Sandisk Extreme Firewire CF reader plugged into the external firewire port.

Sometimes when I insert a card, the PnP beeps, then after a few seconds beeps again. Like it found it then lost it. Removing the card causes the system to reboot a short while later.

Another behavior sequence is insert the card - system recognises it, I can use it, but using the 'safely remove hardware' util causes it to hang - then the reboot.

It seems that if I get a good insert and just remove the card after using it, that it works. After a couple of minutes you hear the beep when it discovers that the card is gone, but no reboot for this.

Any suggestions - possible voltage tweaks, BIOS settings etc that could help ?

Thanks,
Craig.

First check if it happens when the CPU is not overclocked. Also, have you done any stress testing (e.g. Orthos in "blend mode") to verify your CPU/RAM are working well without errors?

Prime95 and MemTest86 both test out fine. The 1394 port is the only issue with this PC.

I'll have to try running stock for a while and see if it repeats.

Make sure your PCI bus speed is set to 33MHz, and your PCIexpress bus set to 100MHz, in the BIOS. The 1394 port may be connected using one of those.
