I'm having a problem a with my GA-P35-DS3L motherboard and before I send it back I wanted to see if anyone knows what might be causing the problem.
I have an E2160 CPU and 2x1GB Crucial Ballistix DR2 800 w/4-4-4-12 timings. I had to change the memory voltage to 2.2V cause that's what the Crucial is spec'd at. I also increased the FSB to 266 and set the memory divider to 3 to run the CPU at 2.4Ghz. It runs fine until you try to restart it after it's been running for a while. Then it starts up for a couple seconds and then it turns off for a few seconds and keeps doing it unless I pull the plug on the power supply (turn off switch actually). After I pull the power and then reconnect it and turn it on, it will do the on/off thing a few more times and then it will boot up.
I have the exact same mother board and has my E2180 @3.2Ghz on a OCZ Vanquiser I bought for $10.
These are the setings I recomend:
Set "System Voltages" to "Auto".
Set the "Performance Enhance" to "Standard"
Set the "SPD" so that the result will be 800Mhz or less.
Set "DRAM DLL" to "Option 2"
Set the "CPU Host Frequency" to 266Mhz
Save and Reboot
I have the same board and would not recommend setting the voltages to 'auto'. This is because the board always sets the voltages too high leading to higher temperatures. Instead maybe use 'auto' to take a peek at the voltages its automatically set to and work your way down.
If your computer is restarting like that something is wrong with your motherboard or PSU. Had the same exact problem twice. Once was the PSU, the other time it was unfortunetaly the motherboad...just replaced GIGABYTE DS3R with cheaper DS3L till replacement comes.
