@Milor123 that’s just how memory displays in cpu-z. 1600mhz ram will be around 800mhz
can try a few things for the 32gb problem

Reported RAM speeds are correct, now the Asus AI tuner auto features reduces the default 800 to lower values in order to achieve other FSB/Clocks, you cant set manually all this, not using the Auto OC from Asus.
Usually you cant stand with 800 (1600Mhz) but increase the FSB manually, raising above 1600Mhz till 1866Mhz youll have to increase a bit the voltages or lower the BLK.
Your Corsair cmd16gx3m2a1600c10 is not reported as 4 slots populated QVL support list for 32Gb use.
EDIT: Well… all i posted i cant and wont confirm… due to mods done, ive seem plenty of mods doing this to mbs… user complains of loosing abilities on OC, so the only ones that can answer to you on that, are the ones that make the mods.

I’ve incresed manually the voltage to 1.65v and change the timming but the results is the same using the mod BIOS. As default in the BIOS set memories in 1333Mhz and i’ve up this value to 1600Mhz But apparently it’s not booting up in Windows even though I changed the timing and voltage, how can disable the feature “Auto OC”? But I don’t think that’s the reason because if it were, why does it work when I use the unmodified BIOS?
For these tests, I am using 3 RAM sticks of 8GB each, even though I really have 32GB. The problem is that with this modified BIOS, there is a bug that causes the screen to stay black if you go over 24GB of RAM, by this reason cant use my 32GB
Hi guys i want share the last .ROM stable updated file, made by @Cursemex , wih Fixes RAM overclock problem, by @Koekieezz
I’ve used UBU tools for update MicroCode and others things avaibles in the program
V4+ResBar+MicroCode+RAMBugfix+Others.zip (5.6 MB)
Note: It must be flash as .ROM using /Gan method.
- This contain the ReBarDxe0.3.ffs version
- Last MicroCode
- VERY IMPORTANT, I AM HAPPY OF DISCOVER IT: Keyboard is “disabled” like a bug, when turn on the pc or reboot. but the trick for solve, (its, you press the reboot bottom in your pc or board, when you see the “Keyboard not detected”, and now in the next reboot you can access to the BIOS using your keyboard)
- Only has been tested using 14 in RebarState.exe for use 3 modules of 8GB of RAM = 24 RAM TOTAL in my pc. According to @Cursemex it dont work in 32GB.
Thank you very much guys, excuseme for the late, I try doing many stability test and I am noob in this.
@Milor123 does plugging your mouse/keyboard into USB 2.0 port fix it ?
USB 3.0 port keyboard doesn’t work on my system (b75m-d3h) too when 4G decoding is enabled. It turns out my BIOS allocates USB 3.0 port into 64-bit address.
see this screenshot of device manager view → resources by type
And these BIOS have a bug with the CpuIo and PciIo that is likely the cause of keyboard not working with 4G decoding. It’s possible to patch it though.
@Milor123 update ?
If you do find your USB controller is allocated there, send the PCI device IDs so I can make a patch to fix it.
Hey bro!!! Sorry for the late.

I can confirm that my method of reboot works in 2.0 and 3.0 ports for temporal solve the bug.
Thank u very much bro!!!
You can try this UEFIPatch (make sure it gets applied)
# PciBus | Add Intel 9 Series XHCI Controller to 64-bit blacklist (fix broken USB in UEFI with 4G decoding)
3C1DE39F-D207-408A-AACC-731CFB7F1DD7 10 P:DE10D301FFFF00000B00000014:8680B18CFFFF00000B00000010
Use MMTool if it’s needed

Thank u very much, but i dont know how use, i could take things that can broken my system xD i am very idiot for this.
Guys i have question @Kuri0 , i am working actually in linux, in a ubuntu. I have a great problem.
I have an issue that occurs every now and then when I restart Linux, for some reason it freezes, and I have to force a restart or something similar. There comes a point where the BIOS seems to have some kind of error and gets stuck just like it does when it doesn’t detect the GPU or when I add more RAM than allowed to enable the REBAR.
After this happens, not even using the CMOS button solves the problem. I have to go and reflash using the rear button of the board and the M7H file, and then reflash the BIOS MOD.
I don’t understand what is happening. This keeps happening very often, every 3 or 4 days, or maybe 5. It’s frustrating; I have reached a point where I think it would be better not to use the modified BIOS anymore.
Please help me, what can I do? If only the CMOS reset would work, it would be more feasible, but I have to reflash the entire BIOS using AFUDOS.exe, and it takes a lot of time to configure everything.
Thank u very much !!!
@Milor123 That issue is probably caused by overclocking fix or maybe updated modules (not ReBarDxe).
FYI if you only use Linux you can just use stock BIOS, it only needs 4G decoding enabled and CSM off and Resizable BAR works.

that weird, I’ve patched the new ffs of your github page in the mod file and the CMOS dont response and always need reflash the stock ROM
Ohhh Can i use it with my stock? Ohh great i need it in linux!
Thank u very much for teach me it. I try do it for now. I love you bro!!!

Seems to be working so far between reboots.
No short beep on restart.
Thanks
EDIT: didn’t apply overclocking fix / MicroCode since they were not shared here
Ohh sorry, For overclocking ram bug, we solved it doing the next:
“replace the guid 842A454A-75E5-408B-8B1C-36420E4E3F21 using UEFITool, replace as is using my nvramsmi module”
(the file was shared by @Koekieezz ). The file is in the next zip
DXEExtracts.rar (2.0 MB)
Photo of conversation with @Koekieezz while try modifiy the ROM file for fix ram:
And the microcode was updated using the automated method with UBU tool
Hi, I have this same issue but for the ASUS Z97 Pro Gamer.
Would this patch allow me to overclock my RAM as it sticks at 1333Mhz when I enable resize bar.
Also, I have the 32GB issue but I have place 3x 8GB and 1 x 4GB giving me 28GB RAM and everything works. I haven’t seen anyone mention that as a solution to sacrificing the whole 8GB Slot.
Anyway, it would be great to be pointed int he right direction? I could maybe patch it myself if I knew where to start learning?
Thanks.
If @Koekieezz posts the OC ram patch I’ll include it in the main post and make a patched bios with updated mC.
