@dsanke - Do you know if this edit, or similar, would be same on Asus Rampage IV Extreme (X79)?
I think Asus already made some of their X79 128GB compatible, but not this one

Hello @dsanke , thanks for this useful post. I'm already using already using one your modded BIOS on my Clevo laptop. I would like to get this 128GB RAM mod working on my Asus ROG MAXIMUS X HERO (non-WiFI model) which is a Z370 board. But, unfortunately I don't have any BIOS editing experience.
This seems to be the latest BIOS update from Asus https://dlcdnets.asus.com/pub/ASUS/mb/LG...O-ASUS-2203.zip

@Lost_N_BIOS helped (REQUEST - ROG MAXIMUS X HERO BIOS Mod to Allow 128GB RAM) with identifying the HEX pattern "C7 86 7F 25 00 00 00 80 00 00". I searched the .cap file included in the zip and it has 2 iterations of this pattern using Bless Hex Editor on Ubuntu. I didn't convert the .cap file to .bin and didn't extract it. I'm kind of noob for that.

According to your first post, it seems support for 128GB is not present on this MB. Would you please be kind enough to help me on this?

Thanks in advance.

@dsanke your mod worked on my Asus ROG Maxumus X Hero Z370 board + i7-8086k processor + 128GB RAM. @Lost_N_BIOS did the mod for me according to your guide. Thank you very much for putting this guide together.
I haven't done any stress test or any thorough test yet. I'll be doing that soon and will post if I find any issues :)

hey @dsanke, i am in a boot loop right now with my Gigabyte Z370 HD3, with my two 16GB ADATA 2666MHz RAM, so what I did was change the bit from 0001 to 8000 as you did, and use me_cleaner to set the HAP bit with -S (--soft-disable)and -O as the command prefix. And used efiflash to flash the BIOS. What should I do now? Could it be a problem that the 16GB RAM could not be used anymore, or the board is bricked?

#20 RE: Make Z370 compatible with 128GB RAM by k6808_8086k 11.11.2019 23:50

@bios_guy if you used https://github.com/corna/me_cleaner , try with "-s" in small letter and try flashing it again. I used "-S" on couple of systems which disabled one my LAN port and another one 3 LAN ports. Using "-s" fixed that issue.

Also, changing 0001 to 8000 would make your board support only 64GB of RAM. If you had 0001, that was ready for 128GB RAM.

https://github.com/corna/me_cleaner/wiki...ltMeDisable-bit - 3rd paragraph from the bottom shows the following.

me_cleaner sets this HAP/AltMeDisable bit when the "-s" (enable only the kill-switch, but don't remove the extra code from the firmware) or the" -S" (enable the kill-switch and remove the extra code from the firmware) are passed.

#21 RE: Make Z370 compatible with 128GB RAM by bios_guy 12.11.2019 11:14

Ohhh to clarify, I think I made a typo, I mean 8000 to 0001, but when I do it with the small s -s, the bios seems not to work, since I tried to backup the bios after update and still see the hex in 8000, that’s why flash with -S the second time. What can I do now, the PC is stuck in a boot loop >_<

@bios_guy - send me your BIOS dump not modified by you, and I will modify it for you to disable the ME FW. Sounds like you aren't doing something right, and I would not suggest using ME Cleaner for this anyway.
If you cannot boot your board now it's probably bricked and you will need flash programmer setup (CH341A + SOIC8 test clip w/ cable)

@bios_guy
For Gigabyte , you need remove MeRecoveryDxe GUID:F1FCD66F-8966-441E-909C-77F211AB9C3E , if it exists. Or it wont let you boot into system when you set HAP bit.
And do not change 0001 to 8000 , just set HAP bit, it's enough.

@dsanke - I asked at #16, but maybe you missed it, do you know how to do this for X79 (Asus)? Many models have BIOS already put out for 128GB, but not Asus Rampage IV Extreme
I tried to find in various BIOS modules, but nothing looked similar. If you have time to check that would be great, thanks

@Lost_N_BIOS
I dont see anyone using R4E and 128G and found problem. I think there is no need to modify. I think all X79 should support 128GB initially.

@dsanke - Thanks for checking on this! I was asked by user to fix here in the forums, maybe he didn't test? I will ask him if he's tested 128GB yet or not.
All I know is MANY Asus X79 got latest BIOS update with +128GB fix added in change logs, and that board and few (2-3 I know of) others didn't get update or new change logs etc.

@Lost_N_BIOS, Here is the Bios without any modification that I was using, F8 for Gigabyte Z370 HD3
https://gofile.io/?c=9QzVNz is the download link, I can't upload it here because it is bigger than 6MB

@bios_guy - is your system bricked now, or what's going on? You could have linked me to the Gigabyte BIOS download, if that is stock BIOS (I assume it is, and will download from them now since I know your board now)
I asked for dump assuming you were using programmer, so MAC ID would be preserved in BIOS and any other board specifics such as serial, UUID, NVRAM etc. Since this is Gigabyte, please tell me how you are flashing etc, that way we get things correct.
If you are using FPT I need you to dump your BIOS with FPT (FPTw -d SPI.Bin), then zip it and then send to me. if you are using Qflash then I can just mod the stock BIOS. If you are just reflashing ME FW region with FPT, then I can use stock BIOS too and send you only a mod ME FW region to use
Need to be sure what/how you are doing things before I proceed with any edits.

Also, please confirm, since it's not latest BIOS, you are using F8 from this page (HD3, not HD3P) correct?

#29 RE: Make Z370 compatible with 128GB RAM by bios_guy 14.11.2019 17:16

I think it is bricked now, there is no way to reset unless I got those hardware to actually reflash it, I flashed with efiflash.exe modified by dsanke, I think it is 0.72 version, so now my PC is just in boot loop. Could you upload the .F8 bin you have modified???

@bios_guy - There is no "Think" only brick or not I have not modified anything, was waiting on answers to all my questions above before I did anything. And if you can't boot to BIOS/Qflash or DOS, then you can't flash anything anyway.
You can try PSU trick method to make backup BIOS kick in, if it will work on your system (See method #2 - do not use method #3 it's not for this BIOS type) - https://www.overclockers.com/forums/show...te-motherboards
If you can't get with PSU trick, and your board does not have BIOS switches, then yes you will need flash programmer + SOIC8 test clip with cable.
