Good point RedSerctor - good troubleshooting requires good documentation.
Base Hardware: 3900XT, 2 x 16MB Trident ZNeo - (PN on the ASUS QVL), 2080TI, 750W Corsair HXI
First attempt: - using Mobo right out of the box:
- DRAM in recommended slots A2 and B2
- Turned on PSU power switch, start light button lit up, Hero logo on
- Turned on power, fans turned on , RGB (connected to blocks) turned on, pump turned on
- Yellow QLED (DRAM) turns immediately on, Q-code flashes a few numbers (too quick to see), then 14,15,14, then 15 (stays on last 15 for about a second), Then entire cycle starts again. Note that it takes a couple of seconds before the RGB on the DRAM to turn on.
First debug attempts (all with the same results):
- move the pair of ram to the A1 / B1 slot
- tried (each) of the single sticks in each of the slots
- reset all of the power cables on the MB
- took a single stick of DD4 from current rig, put it in - same results except that I could see the cycle of the Q-codes: CC, 92, C8, 14, 15 (repeat)
Went back to single stick of the 16MB.
- Held down the clear CMOS button (for 3 seconds) - no impact
- downloaded BIOS 2204, changed file name and copied to USB
- Plugged USB into the USB BIOS flashback port - held the BIOS flashback button - it turned blue, then started slowley flashing (probably for about 5 minutes), then it stopped and turned off
- powered off and on - same results
