x570 Steel Legend stopped running RAM over 2133

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I've had a cleanly built X570 Steel Legend with a 3900x running perfectly for years. In the last year it started freezing. When I did Memtest it showed massive RAM errors. I replaced the Corsair 2x16gb 3200mhz sticks with several variants now and have found the board won't run any RAM over 2133 without producing massive errors. Even a single DIMM. With 4 DIMMS forget it not even 2133 stock. I've tried adjusting voltages but no luck. Is the board done? Any suggestions?

	What voltage were you running it for all the years you've had it? I can't imagine the board itself being involved since it's just some traces and slots. I suppose years of heat-cycling can affect it. But I'm no expert. The CPU's memory controller or its voltage-domain-crossing logic could be on its last legs if it was driven hard over the years. Nothing lasts forever, you know. Maybe you can try re-seating the CPU. I've flooded the AM4 socket with CRC QD Electronic Cleaner on a returned board to fix it up once, but I'm not saying you should try that or anything like that.

	I think you might be right, I have a feeling it's the 3900x's memory controller. I never OCed it, actually ran it in eco (65w) mode as it just ran better, the DIMMs were never pushed above 1.4v when four slots were populated. With brand new corsair b-die it will barely hit 2133mhz at any voltage, even one slot.
