Hi all,
I recently replaced my old TaiChi X370 motherboard with an ASUS TUF Gaming B550M-Plus WiFi II.
Other components from the old machine include a Ryzen 7 3700X, two sticks of Vengeance 16GB 3200C16, and a Radeon RX 5700.
All has been running beautifully for almost a week. Then the graphics suddenly went dead (no artifacts, just off). I confirmed the monitor is good with another PC.
Trying to reboot, the POST beep codes (one long, two short) for the AMIBIOS indicate a video error but the DIMM error light is also lit. I have tried three different known good graphics cards and I get the same error beeps. Cleared the CMOS, updated the BIOS, reseated everything, still no POST at all and still getting the error beeps.
I seem to have narrowed down the issue to dual channel memory: if I just use one stick of RAM in any slot, it works fine. As soon as I have two or four slots filled, the fault light is on and I get the beeps. I can swap the RAM around and get it to boot into Windows with any of the sticks I've tried - as long as it's just one.
I've reseated the CPU, checked all cables, unplugged all peripherals etc.
Does this sound like a faulty motherboard?
Any other ideas of what to try? At the moment I'm inclined to return the mobo under warranty as I can't think of any other cause.
Cheers!
