Hi all,
I realize there are several questions regarding this similar issue, but I don't seem to find any relevant answers yet.

All of the parts for my new PC have arrived (except for the video card) and I have ordered the it 4930k with the Asus Sabertooth x79. I understand that I am required to flashback the BIOS but am a little confused following these instructions : http://event.asus.com/2012/mb/usb_bios_flashback_guide/

Referring to this page: http://support.asus.com/Repair.aspx?no=563&Slanguage=en it seems my version is Rev 1.02 or 1002 as it indicates on my motherboard.

I also noticed though, that in this post: http://www.tomshardware.com/answers/id-1783186/usb-bios...
one of the reply says that "The BIOS version is the last 4 numbers on a very thin white sticker (bar code ) on the extreme right hand edge of the board, next to the SATA ports or the 24 pin ATX power. If your board shipped with BIOS 1203 or earlier you will have to flash the BIOS converter tool first. Then onto flashing BIOS version 2002."

Following that advice, the last 4 digits on the barcode are 4005. I am confused, is my version 1002 or 4005?

The reason I am wondering is that I am unsure which version to download from here: http://www.service.asus.com/#!downloads/c1wax
and whether I need to download the BIOS converter utility.

Could someone please advise me on how to proceed? I will be building the PC tomorrow so I hope to figure it out by then. Using this link: http://www.service.asus.com/#!downloads/c1wax would you be able to direct me towards what exactly I need to download?

Perhaps it is also relevant for me to mention that I will be using windows 7 64bit

Thanks!

Hi,

It's worth mentioning that you do not have BIOS based firmware on your PC, you have UEFI based firmware. The two terms are often used interchangeably for marketing reasons but it's a huge misnomer.

Asus X79 motherboards have a nice feature called USB Flashback which allows for the firmware to be updated without having a CPU installed. I'm not certain if the IvyBridge-E microprocessors will work on X79 motherboards that have older firmware, as sometimes it's only necessary for certain features to be enabled.

When Asus first released their X79 motherboards they were designed with a .ROM firmware file template in mind. Shortly afterwards Asus updated this to a newer .CAP file format which makes it easier to template the firmware internally. All firmware revisions <2000 are .ROM, all >=2000 are .CAP

In order to install a firmware revision that crosses this 1000->2000 barrier it is necessary to run a format converter so that the firmware flashing utility can understand the new file format.

You can look at the sticker that you mentioned to see if this conversion has already been done for you. This may very well be the case as the changeover was made well over a year ago. If the firmware revision that shipped with the board is >=2000 you can simply use USB flashback to install the latest 4000+ revision which have full Ivybridge-E support. If the firmware revision that shipped with the board is <2000 you must use the .ROM to .CAP converter (which is itself in the form of a .ROM file) alongside the latest firmware revision in .CAP format.

It should be pretty straightforward.

Hi Pinhedd, thank you for your concise response.
So if the digits '4005' appear on the sticker, than it is safe to say that my firmware revision is within the > 2000 class, and therefore the firmware will be in the .CAP format.
When I look at the CPU support for the sabertooth x79 on the asus website, I noticed that the core i7-4930k has been supported in versions 4210 and later. Therefore, because my version is 4005 (which is strange seeing as I ordered it online just last week, so you think it would be updated with the most recent version) I will still need to update the firmware by going to the 'download latest BIOS' (which is now version 4302), downloading the .CAP file, rename it to SABERX79.CAP, place it into the white usb slot on the motherboard, and click and hold the button (following the guidelines here: http://event.asus.com/2012/mb/usb_bios_flashback_guide/).
Can you just confirm for me that my assumptions are correct, and that I have understood your post correctly?
Thank you for your time.

That's correct. You would want to update the firmware to revision 4302 using the method in that guide.

The system may be partially functional with an Ivybridge-E microprocessor installed even while older firmware is present. Newer firmware revisions often adjust support for power states, thermal monitoring, new features, and new instruction sets. Alternatively, it may not work at all until the firmware is updated.

I just got a Sabertooth X79 with the Intel i7 4930K Ivy Bridge Six Core

I have not installed yet, and am preparing to put it all together but was reading up on the firmware/bios updates first and seeing if I needed to do so.

Next to the Sabertooth printed on the board it say "Rev 1.02" which means 1002, correct? And since that is greater than 1000 I have the appropriate .CAP firmware, correct?

However, on the little while sticker, it says "4502" which is the latest (10.21.2013) version of the bios anyhow (ordered the board around Dec 1, 2013).

So, that being the case - I should be good to go right? No updating necessary? Or do I still need to update the firmware for any reason?

Revision 1.02 is the revision of the PCB itself, not the firmware. The firmware version is 4502

Ah, thanks.

Either way though - with PCB revision 1.02 and firmware version 4502 (latest according to ASUS site), do I need to update anything currently?

I don't believe so. I think that you're good to go
