Dear Alpharevx,
I’ve this board. To update for your BIOS, there’s any special procedure? Has risks?


Thanks


Dear Alpharevx, seems that the BIOS has some issues. Can you please consult the ASUS FORUM?

Can I get your BIOS with HPET ON in order to test?


Thanks

Hello there, you can flash it using AFUDOS method!
I’m using this version as i’m writing this, risks? i’ve never had any problems doing bios flashes on this motherboard.

Very thanks, the update went smooth as a charm.

Testing.

Thanks again

Dear Alpharevx,
I found a little problem with your BIOS version. Can you please consult the Asus forum https://rog.asus.com/forum/showthread.ph…re-0-and-time-0.

Can I get your BIOS with HPET ON in order to test?

Thanks

What problem dude? lol im working with this version of BIOS right now, you can turn HPET ON, go to PCH Settings, you can turn it On or Off.

Try your test with HPET ON, turn it ON from the PCH Settings section :smiley:

You are the Man. Didn’t noticed that toggle ON/OFF. With enable, the PC able to pass the tests.


Keep up with the good work.

Thanks

You’re most welcome dude! :smiley:

Btw if you have an idea, what are the best drivers for this motherboard, Running Win10 Pro x64?

Well, the only driver that seems to have some performance impact is the RST driver. As per Fernando’s advice I use the 13.2.8.1002.

Big thx for this. Bios Updated. :slight_smile:

Well,
After testing with the game I play (Battlefield 1), I get best performance with HPET ON.

I7 4790K @4.7Ghz
2x8Gb @2133Mhz
Geforce 1060
Win10

How much FPS differance?

Well, I’ve the FPS locked to 100. with the HPET OFF, I have FPS drops (80~100) and shuttering. All gone with HPET ON.

Hi,
just wanted to report here; I found this thread while searching for the (long overdue) spectre/meltdown fix bios from Asus which is still not available.
I have never flashed a file with AFUDOS before and it worked like a charm. Thanks!

Let me just drop some keywords for google here, hoping that more people find it.

Also, here’s how to create a bootable flash drive: https://www.howtogeek.com/136987/how-to-…-dos-usb-drive/
And here’s the link to AFUDOS that supports the /GAN command: https://mega.nz/#!54oxwbJA!tkghDael8JgY3…jnlb4g0lz9Ei9mg
Create flash drive, put afudos and bios.rom on it, boot from drive, enter afudos bios.rom /gan and profit

I’m using this BIOS modded by Alpharevx (great work!) and I leave you some recommendations:

Turn on the HPET and let the Windows (10) manage it. Windows 10 no longer uses HPET by default (it uses TSC, Time Stamp Counter). If a program requests HPET instead of TSC, W10 will provide.

Your LAN card MAC adress was reset to 88:88:88:88:87:88. Please use below to fix

Tip: The original MAC address is on a sticker on the MB 24 pin connector.

Where can i get modded bios for my Z97 Pro Wifi/AC?

Thanks Alpharevx for this bios mod …
and thanks jrmpt for Mac editor …
As jrmpt, HPET OFF = slow performance, HPET ON = better performance (GTA 5 testing)

Hello

Hello! Sorry to ressurect this old thread but it’s the only place on the internet I can find anything about turning OFF HPET on my Z97 PRO GAMER motherboard. (no option in BIOS by default)

I downloaded your modded BIOS Alpharevx, however it’s in .ROM format. As far as I know you need .CAP format to be able to flash the Z97 PRO GAMER. So I’m very confused, also why is the modded BIOS named 9901? The latest official BIOS version from ASUS is 2203?

Anyway, can anyone help me? I’d like to try out this BIOS but I need it in .CAP format!

Thanks x

Hi.

Create a Bootable DOS USB Drive: here

Download the BIOS and rename it for example to AsusZ97PROG.rom
Copy that file to the USB pen

Download AFUDOS.EXE here
Copy the file to the USB pen

Inside the pen create a file named update.txt. Open that file and paste:
AFUDOS AsusZ97PROG.rom /GAN
Save, exit. rename the file from update.txt to update.bat

Boot the pc from the pen. run the update.bat
Done

Inside the BIOS, load the optimized defaults and turn the HPET ON. You may want to correct the mac address here
