By defult the 32 bit is enable you have to disable the 32 in bios and set 64 bit you can only have one enabled.
I have 128gb ram so not run into that issue and i have a770 arc 16gb.
The only issue i have is with all cores turbo i cant overclock gpu or i get power throtle and the pc restarts.
The ram power i never relly got into i only did timings i have eec ddr4 server ram the most my cpus will take is 1866 even though they are 3200.
Can you describe how you patched the BIOS for 64 bit addressing? These instructions

Hey guys,
I have a Dell Precision 7910 Rack. I would Like to integrate Rebar in my bios.
It is really Hard to understand what I Need to do, to get this work. It would be very nice if someone could help me with this 
Hello everyone. Same request for the said motherboard X99A Gaming Pro Carbon but what I only require is to have the Rebar enable.
The BIOS V1.40 can be downloaded with this link from MSI official website
https://www.msi.com/Motherboard/X99A-GAMING-PRO-CARBON/support
Very much appreciated if someone can help me out with this request
I tried using the MMTOOL but seems I can’t seem to find the value PCI Bus to insert the RebarDXE.fss
I did just want to chime in on top for of the rather plethora of otehrs above - that any help in writing out a more friendly and comprehensive guide in steps would be greatly appreciated. I have a Z370 I’d like to get this done on, and I am starting to think anoyone who’s had success in any of my objectives for that board is either lying through their teeth about their accomplishments or ESL…
Please help if you’re able to be a bit more noob-friendly in how to get this accomplished cleanly but sharply. I understand (after much reading), how to to a BIOS dump off either my own stock or the image/bin/.exe I used originally. But it never wants to load nicely like it does in all the vids and some people drag it on something else.

Thank you in advance,
if someone could add a rebar feature for my bios 3503 MAXIMUS VII FORMULA please = MAXIMUS VII FORMULA - Support
Hello @ren o/
Are you able to make a backup of your current firmware?
Your chip will probably have the MAC Address, Serial Number and UUID stored.
Once you have it saved, you can then do the mod on the backed up file.
If you mod and force-flash the stock file, you may loose these numbers.
Best regards,

the bios firmware im using the stock 3503 right now, the problem when i do it on my end i get the error = failed to write rebarstate uefi variable when entering 32
Did you apply the patches ?
Do you need a 2^32 BAR SIze How much GPU V-RAM ?
here you go = rx 580, the patch wouldnt go through, the problem is this part = 1. Run AmiBoardInfoTool -a AmiBoardInfo.efi -d DSDT.aml. This will extract the compiled DSDT from AmiBoardInfo to DSDT.aml , i tried copying the command in windows it doesnt work, if someone can bios mod 3503 from asus maximus vii formula by adding resizable bar to it, also add BdwUSB3.txt that would be great
ASRock Fatal1ty 990FX Killer (PCB ver 3.00)
I would like Rebar support added.
HP z240 with e3-1240 v6 and intel arc b570 is rebar a possibility? I can dump the bios with a chip clip willing to pay for mod too I have no problem doing that
Hi everyone,
My motherboard is a Gigabyte Z370 Aorus Gaming 3. Im forced to stay at f10 (or earlier) version of bios, because F11+ bioses doesnt allow the enabling of “Native PCIe” and / or “Native ASPM” (using setup_var, amisetupwriter, AMISCE…) and something more. Official ReBar comes with F15c but breaks other critical things (at least for me) as i said before.
I made an issue on GitHub already but the repo looks kinda dusty (i must say i think its normal and fine).
Can I have some help? I can use my A770 with a 16GB BAR, or my A380 with a 8GB bar… when its connected to the PCH port only. If i move my A770 or A380 to the CPU PCIe port… no POST (5 short beeps). If i keep enabled the iGPU, dev manager says “Code 12” about dGPU.
If I use both gpus cards it behaves the same (connected to the cpu pcie = code 12, connected to the pch pcie = fully functional with rebar).
@ugtuner I think i can do it for free XD. I think a downloadable bios rom from hp is enough (instead a full bios dump). Please post one
Edited. Reason: merging 2 messages (should i, right?)
