I am attempting to keep a running change-log of the BIOS updates for the X58 3X-SLI Classified Limited Edition (part number 141-BL-E759-XX). This should be useful for people who miss an update. It is highly recommended to quickly browse the "discussion" link for each BIOS before installing it.
 
Most recent update is on top. The discussion link will send you to the relevant forum topic discussing that particular BIOS revision (which will also give you links to all available download types), and the download link will give you a direct link to the relevant .bin file.
Unless otherwise noted, all changes are cumulative (so each latest BIOS will contain the changes of all the previous BIOSes)

• Fixes known issues with VT (Virtualization Technology), VT should now be properly enabled or disabled and also should not need to double-pump boot on a warm reboot.
• Fix spacing on Intel RAID Rom Text (making it a little bit easier to read the POST screen)

• Fix cold reset when VT is enabled (removes the clock reset causing the “double-pump boot”, but be advised VT may not work correctly without a cold reboot.) Note: many users seem to have problems with VT not working correctly with this BIOS.
• Adds screen clear before invoking option rom (Fix the screen read-out which was dificult to read/garbled in the previous BIOS)
• Updates Intel RAID Rom to 10.5.0.744 (NOTE: The Acceleration feature is not usable on X58 chipset, it's a feature that will be available on future boards such as the X68). EVGA had to have this RAID ROM customized to fit into the Award BIOS
• Updates CPU Microcode to version 13
• Updates Intel Phoenix AHCI Rom to 1.07.10
• Updates JMicron ROM to 1.07.25
• Updates Realtek PXE Rom to 2.39
• This BIOS will have problems reading drive partitions large than 2 Terabytes

·         Extreme cooling mode improvements when using a 6-core CPU – BIOS shows 2.055v CPU PLL when X-Cool jumper is moved (1.60v Real)

Changes:
·         Updates VT to correct issue with not enabling on specific setups. (To paraphrase EVGA_Jacob: The Previous BIOS update had some issues with VT on some setups, this BIOS reverts back to the old method before these issues were introduced - so when VT is enabled, the system will do a full shutdown/restart when warm re-booting)
·         Corrects issue where memory timings change after S3 resume on some configurations.

Changes:
·         Supports 32nm Desktop CPUs (32nm Xeons might NOT work)
·         Added "Turbo Performance" option (may boost performance if enabled) Note: Defualts to off.  This tweek is intended for 32nm Gulftown core processors; "enabling it for bloomfield should yield no benefit and may have the 2:8 ratio limitation with bloomfield"  Enabling this on a 45nm CPU may cause issues including incorrect memory ratios
·         Fixes 1866MHz Memory Ratio
·         Removes the Boot Logo/Splash Screen (the logo was taking up too much memory in the BIOS and was removed to make space for more BIOS code) Note: the Boot Logo option is still listed in the BIOS settings screen, this option can now be ignored.

Updated to include the new S22D BIOS.

I also added the notes from shamino and dejanh, hopefully I reported them correctly.  If someone could confirm that the changes are correct, especially for the poll clockgen/qpi ratio sequences for S22A and S22D it would be appreciated.

Thanks dejanh

Davabled, your link to S22D discussion poins to S22A instead.

Updated to include the "44" official BIOS.
 
I also added a note to the 43 & 44 BIOS that 32nm Xeons might NOT work... let me know if the official word on this changes, and I'll change the notes.
 
p.s.  anybody know what the plural of BIOS is?  BIOSs?  BIOS's?  BIOSes?

Bios 49 does that support 32nm cpu? since it newer bio than 44?

2slick4u

Bios 49 does that support 32nm cpu? since it newer bio than 44?

I would assume it's the same as the previous BIOS, in that 32nm 6-core XEONs aren't officially supported.  You might be better off asking that question in the discussion thread.

Any chance you could post up S61J? I hear thats a winner

Oh alright, thats fine. I apologize for the misunderstanding I thought that S61J was for the 759 as someone had mentioned I ought to try it, but I myself am also on a 759 board and am already on 22D. Thanks for the clarity.

Davabled; Thank you for the archives. I was about to post about where I can find these. Again, thanks again.
 
EDIT
 
Not to overrun JacobF's thread but maybe add the .iso download files along with the bin's here in your thread? Just an idea.

Fair enough. It would probably create more chaos...

Had to re-type the whole thing, but I think it's a little better now.  Added references to which BIOS is the recommended one depending on whether one uses a Quad-Core or Six-Core CPU... let me know what you guys think.

Hopefully adding future BIOS updates to the list will be easier from now on... *knocks on wood*

Just a question, on whether one uses a Quad-Core or Six-Core CPU bios, what is that based on?

Experience? member feedback? OC potential?

I have an i7 920.

EDIT: How to i change my name ? Whats with it being my email

Updated to include BIOS 59.   So far it looks like the only difference from BIOS 56 is a possible fix for a specific RAID issue.

Updated to include the Beta BIOS 70, our first BETA since January.
