Black Screen Issue When Enabling 4G Decoding on X79G V1.51 Motherboard about rebaruefi HOT 7 CLOSED

Is CSM and all legacy stuff off ? CSM off should work on it's own, if it doesn't then there's an issue with your GPU VBIOS which Common Issues in wiki says how to fix

Also the guide says DSDT patching is NOT needed on HEDT systems like X79.

Btw you can fix your Z97 board just flash back stock bios.

Yes, it's all off, and for the Z97, still waiting for the new BIOS chip. Ill get back to it now since you confirmed DSDT is not needed. I'm on UEFIPatch now. Just to clarify, I can proceed with the next step without enabling 4G encoding first? Thank you.

unfortunately, after everything I tried, I still can't enable 4G Decoding... even after completing the BIOS Flash successfully. Still getting black screen whin 4G is on.

These Chinese X79/X99 boards typically have working 4G decoding already, atleast for others with them.

thats because they tend to not have actual x79/x99 chipsets on them.

The GTX 10, GTX 16 and RTX 20 have no support for ReBar, its only available after Ampere

Afaik the chipset doesn't matter for resizable bar. Issue is that the OEM didn't correctly do 4G decoding

Closing because this issue is most likely fixed now, see #48
