Hi All.

This is my first reddit post ever!

Anyhow. Regardless to the hate I am still rocking X99 haswell hardware because I love it!

For anyone who is interested. I managed to enable ReBar on the Asus X99-S motherboard and thought I would share the Bios file should you want to use it. You will need to set the Rebar size using RebarState (Github).

I hope someone finds this of use. Has made significant gains on my RX7600 and I am not having any issues with VRAM saturation on any of the games I play (Mostly AAA titles).

See attached. Is still Aptios Signed so can be flashed with USB Flashback. :)

This board has a 16gb limit. So I am set to 8gb as my card is 8gb.

Flash is successful with no issues. CSM needs to be disabled, and Enable 4G Encoding Enabled. Secure boot can be left alone.
