Ok, looks like at least one bad module. Set the board to XMP. Booted to memtest with one module. All fine. Replaced with another module and all went red immediatly. Took that out and added a second module to the first that passed and all went fine. Running stable now with two tested modules. Never tested the fourth module as no point. Seems definitive that one is bad.
How to RMA? Thanks!
