If ECC is showing as disabled in the Validation link, then its probably an issue with the GPU bios. Im using the Asus XOC 1000w bios on a Strix 4090. I have no interest in switching back to the stock BIOS.
I can assure you the settings I'm using are 100% stable. I use these exact OC settings for running renders in Octane, V-Ray, Redshift, & Revit all day long. Never experience crashes, freezes, artifacts, hangs or stutters. Even with ECC set to Disabled. Gaming is also a flawless experience with these settings as weIl.
I experience nothing but total stability with the settings i used for this run.
Sorry, but im not switching back to the stock bios just for the sake of ECC registering/working
Either way, its still quite stable as it is
