I have a z390 Phantom Gaming 4s/AC motherboard that i purchased about 2 months ago. Whenever My PC wakes up from sleep mode the Dram LED is highlighted as if there is an error with my ram. I've searched the internet and other users of this motherboard have said they updated their BIOS and was good to go, however ASROCK does not have this exact motherboard on their website to update bios and its not detecting any version of bios that I Download to flash.

Hi, sorry to reply to an old post but I have this exact issue. The DRAM light is on every time I wake up my pc from sleep mode and only shuts off if I restart or shut down my pc. I can't seem to find the BIOS version required to update the Z390 Phantom Gaming 4S/ac model. I still have the BIOS version from 2019. Could someone let me know if a solution was found?
