@lev - maybe your mod was not done correctly? Did you do what I mentioned at post #10, looks like it in your image. On this, can you see "My Favorites" at all in BIOS? If not, then it may also need done there too, but really shouldn't
You may also need AMIBCP edit on top of that (Or only AMIBCP edit and not this setup edit). When I first make mod BIOS for people this is the first thing I send out, a single setting change made three ways, to see which is proper for that particular BIOS/System, since not all are same.
There is also another way to make similar edit as above, removing all contents inside the "Suppress If" to outside it, by moving the "End If's" to be in front of all the actual settings you want to reveal. However, this wouldn't be needed here as the way to fix it, just speaking in general on modding there.

Here is a typical package I'd sent to someone to test setting reveal, before I got started on unlocking the entire BIOS for them.
http://www.filedropper.com/lev-textx3

Test in the following order, once the setting appears, then stop, no need to test the next BIOS at all.

1. Setup only edit - SetO.bin
2. AMIBCP edit, to change Access Level to Supervisor (actually AMITSE/SetupData Body edit) - AmitO.bin << This file, location in regular UEFITool >> B1DA0ADF-4F77-4070-A88E-BFFE1C60529A >> EE4E5898-3914-4259-9D6E-DC7BD79403CF >> (Body of this >> FE612B72-203C-47B1-8560-A66D946EB371)
3. Both 1+2 ^^ - Both of the above - AMITSetB.bin

Rename all to stock name.extension (one at a time), I'm not sure if that's required for Asrock BIOS, but maybe you already know. If it's not required, then no need!
If it's required, do it one at a time and only copy one to USB per flash, so you can remember which is which so you know which method your BIOS needs for edits to unlock hidden settings.

* Edit - Hey! Wait a second here, can you even see the submenu this setting is in, by default I mean? OC Tweaker >> CPU Config (submenu) can you see that?
If yes, OK, nothing more needed than one of the above edits. If you can't see CPU config Submenu in OC Tweaker by default then other mods are needed first

@Lost_N_BIOS it seems only AMIBCP edit is required for this Asrock board. I can see the AVX2 setting and configure it after flashing the number 2 option. Sadly, it's not helping with my overclock as much as I had hoped. It does not reduce the multiplier when AVX/AVX2 workloads are present - only AVX2. When I run an AVX workload my system looks up with the higher OC. :( But thanks for the kind assistance and for helping me learn more about BIOS mods!

@lev - thanks for quick report back, I'll make a note of this in my folder for this BIOS in case someone asks later.
All BIOS are different, so I always start with a set of three like above, on a setting or two, before I start a mod BIOS with lots of changes, this way you know what works for hidden settings before you start trying to unhide a lot at once.

I wondered about that, when it said AVX2 instead of AVX. Why make this setting and not apply it to AVX as well, instead of only AVX2. They need setting for each one!
I've not used AVX2, does it make CPU even hotter than AVX loads? If yes, maybe that is why only AVX2 gets this setting, while we have to deal with that hot load at AVX loads since it's not as bad as AVX2 (if that's worse)

You're welcome!

@Lost_N_BIOS, perhaps they were planning to implent both but stopped BIOS development and thats why it was hidden? It makes no sense to me to implement AVX2 only. I was hoping it would do both even though it said AVX2. I don't use workloads with either that I know of, however, I often use open source and could never know when someone might include AVX dependencies. I'm not going to check everything to see if it might possibly use AVX... I used Aida 64 to generate seperate AVX and AVX2 workloads to test with. I got my OC to 5 GHZ, but at that speed - AVX causes lockup. I had to back it off to 4.7 GHZ to still have a system that can handle AVX.

Edit: Also, FYI asrock does not require to rename BIOS file to exact original name (I can flash same name with .old instead of .80 file extension) in order to flash it, but I always do it. It does do some sort of validation of the file/name as it scans the USB drive and presents options if there are many files.

Hi @Lost_N_BIOS ,
I've followed this procedure, tried many bios versions but still can't get my Asus X99-Pro to display the AVX offset on the menus. I tried to check the differences on the 3 different bios on the zip file provided for the case of this thread, to check if something was missing, or was doing something wrong, but other that the values on the numeric fields i don't see any difference.
I am attaching file with original and modded bios, if you have time for a quick check if something is wrong. I would appreciate a lot.
The file is: ASUS_X99-PRO_BIOS-ORIGINAL_AND_MODDED

Than You.

@lev - sorry for late reply! Yes, maybe that's reason? Or, maybe they will add both later. Good to know about BIOS name and flashing on this model, some Asrock need it to be the same I think, or maybe only a few require that?
Or, do you just mean extension doesn't matter, but actual name does?

@nuno169 - The three BIOS I posted above at post #16 for test are not same at all, BIOS 1 & two have different edits, and BIOS 3 is combo of 1+2 (same probably true for BIOS at post #6 too, I didn't check).
However, none of that applies to your board from post #16, since you have an Asus board, those files, method, and test results apply to that Asrock board BIOS Only.

Method to unlock this for your board is at post #8, unless the E WS is different than the PRO for this edit and it may be (I mean method required, 3 methods outlined at post #16). Extract BIOS body from capsule, do the mod, insert back into capsule via hex, flash via USB Flashback.
If you do not do that, then you have unsigned capsule probably, will not flashback. Here is mod BIOS, flash via USB Flashback ONLY (Stop if your board does not have USB Flashback and let me know, do not try to flash using other methods)

I checked your mod BIOS, looks OK to me as far as this mod itself goes, but this is bad BIOS rebuild (missing 2 x critical pad files).
I would have advised to never flash this BIOS, you're lucky it didn't brick! Maybe it never flashed in due to this, did USB Flashback work normally?


Here is properly edited BIOS, flash via USB Flashback only, if this does not work/show the setting, then I need to make you test set so we can see which method your board needs -

Hi, Sorry for late reply but it's due to being unable to flashback.
My modded bios was not by flashback, and it wasn't really updating the bios but I was thinking it was.
Even with your modded bios it is not flashbacking.
I opened your bios and I believe it is with same issue mine was, but I might be wrong.
But after long try and error, I was able to update the bios body by FPT, disabling the secure boot, and in mine bios as well in your bios it shows the avx offset option finally, However when changing it from auto, it really doesn't change anything (at least reported on cpu speed/multiplier) when on avx/avx2 workloads (tried both), and even seems to me that is causes some minor "hangs" on responsiveness of the system.
Is there a big difference between the 2 methods? That can cause the option to not be properly applied?
Thank you!

@nuno169 - Mod BIOS should be flashed by USB Flashback, if that's not working but you can USB Flashback stock BIOS, then it means bad BIOS image (ie don't try to flash it with anything else, such as AFU meant for decades older BIOS)
My BIOS is fine to flashback, sounds like your USB Stick not compatible, or something in your flashback method is not correct.

AVX does not affect CPU multiplier as far as I know, but I'm not 100% sure what it does to a workload. I do think you have to run some specific AVX test to make it be used though.
You can see if it's enabled/disable in the little CPU-z like window of HWINFO64 (I think)

No, you edited BIOS in same proper way as I did, to make the setting visible in BIOS, that's all that's needed for this, once visible it applies the same.
I was only saying your BIOS rebuild was bad, not the mod for the setting itself (that was fine)

@Lost_N_BIOS



Hello .
And for ASUS X99-E WS / USB 3.1 for the latest version of BIOS 4001 can be done.
Thanks .

And can you just rearrange SETUP from post number 6 to your BIOS ?

Done .

@mimixa - Sorry, I don't understand what you are asking at end of post #24. Nor, do I understand what image is above.
Do you still need help with the edit, or did you get it done yourself?

@Lost_N_BIOS

Thanks, I did everything.
I extracted Setup and did
find 0A 82 12 06 02 04 00 00 1C 90 54 06 55 06 3F 28
replace 0A 82 12 06 02 04 FF 00 1C 90 54 06 55 06 3F 28
I now have an AVX Core Ratio Negative Offset

Check, in my opinion everything turned out correctly

Dear mimixa,

is it possible that you upload the BIOS file again, the link you posted is not working anymore. Or maybe somone other can do the modification for me.
I am still looking for the latest bios (4001) with AVX Core ratio negative offset for my mainboard Asus X99-E WS. Thank you.
