GA-N380SLI-DQ6 warm reboot issue...

[mjrtoo]

When I boot my machine cold, the system works very well, but, if I need to do a quick restart, like a save and exit from the BIOS for example, the computer starts to reboot, but then shuts down immediatly. If I wait even five seconds before I try to turn the system on again it works fine. I have bumped the DDR2 voltage to 2.2v, the voltage specified on the RAM itself but didn't help at all.

I also have the FAIL message in the BIOS for the DDR2 rails, and everything is set to default settings in the BIOS, everything is set at default, just not PSU related settings.

Any thoughts? Power supply issue?

I do have a conversation going with Gigabyte as well.

This mobo only has 1 revision for the BIOS, FA.

I seem to have solved my issue, here are the steps I followed if you're having simillar issues, hopefully they help you out.

1) Re-flash the BIOS with @BIOS, checking both the Clear DMI and Clear PnP Pool Data checkboxes.
2) Clear CMOS.
3) Reboot into the BIOS and select 'Load Optomized Defaults'
4) Change the DDR2 voltage level in the M.I.T settings page to .025 voltage level greater than your RAM states. IE my Corsair ram requires 2.2v to operate so in the DDR voltage setting I selected + .425 rather than just .4 (the normal setting is 1.8v)
5) Save and Exit

Be careful with the DDR voltage, start with your RAM manufacturers recommended level and increment the lowest level until it seems work reliably. I used Everest to monitor the levels and did find that I'm supplying 2.225 volts but it still only reads 2.1, must be a funky power supply or BIOS issue.
