Good information.
There are two BIOS updates listed at Asus P5Q3 Deluxe.
Both mention - 'Enhance the compatibility with certain memory'.
If your comfortable with updating the BIOS, upgrade to 2105.
Manually set your DRAM frequency to 666MHz.
Manually set your first four RAM timings to 7-7-7-20, leave the rest on 'Auto'.
You can leave the "Command Rate' at 2T.
Leave the DRAM and NB voltages where they are for now.
Test with memtest86+ for a full 7 passes, best to run overnight.
If memtest86+ passes then run Prime95 torture test.
CPU - Stress Test with Prime95
First open Real Temp to monitor CPU temperatures, don't go over 77.4°C.
Open Prime95 and stop the test if it is running, in Advanced tab select 'Round off checking', in the Options tab select 'Torture Test...', in the window that opens select 'Blend', after 'Number of torture test threads to run' enter 2, then click OK to start the test.
For checking CPU/RAM stability 2 hours should be adequate.
