I purchased an Arc A750 Gpu, and was trying to enable resizable bar on my dell G5 5000 desktop. I dumped bios. Opened in UEFI tool and searched for above 4G and found the option. I enabled it in grub setup but 4g decoding is still disabled.
This is how the part in the dump looks. looks. I also tried adjusting apeture size to 2048 to force it to enable automatically, but still GPU Z shows no enabled. I assume its something to do with these greyoutif and suppressif. I also tried to set the opt out var to 1 as well as thats how I interpreted that part of the Suppress statement but still no avail. New to this whole thing, Any advice would be welcome. I can provide bios on request as I am not able to use attachments.
