I just flashed the WS Pro BIOS on my P6T deluxe V2 and can confirm that there are PCI IRQ issues when using multiple PCI slots. I had to remove the GPU I used for 2nd screen, installed in the lowest PCI slot. (not a problem as I figured out how to correctly enable HDMI audio through multiple outputs on my main GPU)


So far we can confirm that at least the top x4 and bottom x16 slot do not work when a card is installed in the main x16 slot, on both the V1 and V2 mobo. Hardy, were you using other PCI slots as well? It would be good to know if a WS Pro crossflash actually only allows a single PCI card.

First off thanks for your work. Flashing a raw WS pro 1205 bios always seemed sketchy to me and it's great to have updated microcodes, even though I run fast and loose with no spectre or meltdown protection.


I was having some confusion following the flash instructions on your post on page 37. What worked 100% for me was simply using unetbootin to create a FreeDOS 1.0 bootable USB, and selecting "Live CD...With HIMEM" when booting into the USB. Next all I had to do was cd C:\ to reach the main USB drive and execute the "afu236u /i[BIOS file name].rom /pbnc /n" command. This was with the AFU236U and bios file placed directly into the USB card, not in a subfolder.

Your post is the most referenced thing when searching for P6T flashing, could you please update it to remove old info and clarify/simplify the process?

senstivz Hello i have this motherboard with 6x4 komputerbay 1600mhz non ecc unbuffered memory, and x5680, im having a lot of problems with this setup, if i put all the ram i keep getting memory management bsod, with 1 stick kingston 1333mhz everything works, when testing with aida64 I get hardware failure, anyone know if updating to a custom bios might fix it?

Yes, I'd go with the P6TWS4 BIOS then. Good luck!

Greetings! Sorry for the confusing naming scheme. The first one is P6X58D-E BIOS with an Intel option ROM from the 15.X family. The p6tdeluxev2_mod_2.rom has newer microcodes and OROMs, but is otherwise the standard P6T Deluxe V2 BIOS.

Which one should you flash to? It depends a bit on your preferences and your CPU, I personally was using the P6TWS4.rom for the last year. The P6X58D-E BIOS has some disadvantages of which the always locked in turbo multiplier was the biggest problem and caused instabilities for me. If you have one of the lower speced Xeons with a turbo multiplier below 20, this shouldn't be a problem. But for the X5650 and above, I'd recommend the P6TWS BIOS. Even though it only supports older Intel OROMs, I worked around my issues with it (adding a SSD as boot drive). It also supports unbufferd ECC, and if you've got a mouse with LED, it supports ErP energy savings that turns the USB slots off if your PC is shutdown.

This allows me to use a much newer Intel Option Rom (OROM) for my 2 x 2TB SSHDs in RAID-0 and contains the option to use a voltage offset (which the original BIOS did not have). Thus I am now able to use my Xeon E5645 @ 2.4 Ghz @ 1.03 V at idle (runs @ 3.8 Ghz @ 1.18 V under load). Also thanks to the new OROM I get better results for my SSHDs. Use it at your own risk, you'll find the necessary tools here : https://drive.google.com/open?id=0Bx...mt1b201Q1RQS00

(Update As I have upgraded my CPU to a X5650, I have also uploaded a modified P6TWS Pro BIOS with the newest Microcode, but with an older 10.x Intel Option ROM with TRIM support though.

Advantages: 1) High TDP lets you overclock beyond the TDP limit of your CPU, 2) Turbo mode can be disabled, 3) unbuffered ECC-RAM support (works with the other BIOS in non-ECC mode as well)

Disadvantages: 1) No dynamic voltage regulation, 2) no newer Intel Option Roms beyond 10.x, 3) Firewire does not work

What's new?
mod153mc2.rom

- much newer Microcode (from June/August 2015) for Nehalem and Westmere CPUs (CPUID: 06A4, 06A5 and 06C2), deleted support for engineering samples (CPUID: 06A0 and 06C0)
- Intel Option ROM: 8086-2822_v15032675.bin (tested and works with my 2x 2 TB SSHD RAID-0, also got it to work with the newer 8086-2822_v15102545.bin and versions below, all OROMs newer than that fail to load the RAID array due to size)
- deleted the ASUS splash screen

The mod153mc3 version contains all of the above and additionally uses a modified Marvell LAN Option ROM (same version 11ab-4380_v66813.bin) which is untested and might not work due to size.

What is known not to work?
- the top PCIe x4 slot doesn't work anymore
- ASUS Express Gate is recognized as a *HiSpeed* USB Mass Storage Device, which can be disabled in Windows
- the CPU TURBO cannot be disabled

Flashing process:
Assuming you are currently on the stock BIOS of your P6T Deluxe V2, you'll need to flash the new P6X58D-E BIOS with an engineering version of AFUDOS. EZFlash won't accept it! The file provided here is AFU236U.exe and will do the job.

1.) You'll need a bootable USB stick with the aforementioned AFUDOS version and the BIOS file. Make sure that it runs in HIGHMEM mode or you'll get an error while trying to flash the BIOS. Some USB-Boot-Tools fail to do so.

2.) Assuming you are in the right directory where the files are located type the following into the command prompt (*it promptly will start the flashing process without further warning*)

afu236u /iBIOSFILE /pbnc /n

Notice that there is no space between the /i and the name of the BIOS file.

3.) After restart, you should be greeted with the new BIOS.


*updated both BIOS files with new Microcode for Nehalem and Westmere from May 2018* --> mod156 for the P6X58D-E / the p6tws4 for that board.

Hey so I just picked up a p6t deluxe v2 to play around with and I see that you have mod156.rom and p6tdeluxev2_mod_2.rom, what are their differences? Which one should I flash to?

I did some investigation and in order for me to boot up from Windows 10 installer, I needed to disable VT-d, but I need that feature as I plan to run Unraid with this motherboard and run Windows 10 VM. Any recommendation on how I should proceed?

BIOS Ver: 1408 + spectre/meltdown patch
I did some research on this issue some time ago but haven't found a workaround to get it working (hence only disabling this feature would let you install Windows 10). As far as I remember this was a BIOS implementation issue hence only ASUS could fix it. But it could also be a hardware issue, I remember some dmesg-entries in Linux while installing a distribution with VT-d enabled.

Can you disable it, install and re-enable?
