Windows Installation

• Download the correct .zip file below for your motherboard:

         134-KS-E279-KR - EVGA Z270 Classified K - v1.08
         132-KS-E277-KR - EVGA Z270 FTW - v1.07
         111-KS-E272-KR - EVGA Z270 Stinger - v1.06

• First go into your BIOS and load defaults, save and exit
• Close all open programs.
• Go into the folder where you unzipped this package and open update.bat
• Press Y to start the flash process
• DO NOT TURN OFF POWER OR RESET DURING THE FLASH PROCESS
• After the flashing is finished, the system will automatically shut down. Then power on again and go into BIOS to setup.
• NOTE: If flash box immediately closes after flash attempt, the flash may need to be ran from a CMD prompt with administrator privileges or DOS version.

  
BIOS Installation

• Extract the contents of .zip file to USB flash drive (must be formatted as FAT32)
• Reboot the machine and go into the system BIOS

• From the BIOS, navigate to the Save & Exit tab and open "Select BIOS File."
• Select the .bin file you wish to flash.

[New BIOS added 3/27]

I'm sure it's a bit late, but make sure to unzip the folder prior to trying to flash the BIOS.

So what was the reason for removing the BIOS updates?

Read post #4.

That's what I just got done reading :). Thanks quadlatte for the help,

Any word on when the next update will be released?

EVGA released the updates for X299 yesterday. I'd expect ours to roll out "soon."

"Soon" is now here.  The latest microcode updates are now available.

Following error trying to download E277 and E272. No problems for E279.
 

404 - File or directory not found.

The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Thanks. Fixed.
 
Please redownload E279, as it was linked to the old Spectre microcode file (v1.07), whereas the new one is v1.08.

Thanks. Fixed.

Thank you!

YW.  Please note my edit above.  Make sure you grab version 1.08 for the E279.

Thanks LeeM, I tried to download all of them just to test links as when I tried to download mine, the E277 one, I got the 404 error.

Thanks.  I always appreciate an assist.

RE: EVGA Z270 Stinger
 
Dark Mode still doesn't disable the M.2 Key-M Activity LED (Page 10/11 in the manual). With a clear side case (NZXT H200i), this is still extremely annoying. Any chance EVGA will consider a fix? I've previously reported this through support channels with no response to date.
 
I'd honestly rip the LED off the board if I weren't concerned with EVGA's potential warranty response.
 
This problem has been there for 1.04 and 1.05 as well. My board shipped with 1.04, so I don't know if prior bios' were impacted.

just updated the bios and it killed my nvme speeds, like 100k off the iops read and writes and about 500MB/s off the reads. not good at all.

Our internal testing with an Intel 600P and a Samsung 960EVO show negligible differences between BIOS 1.05 and 1.07.  I wonder if something else might be going on.

quadlatte
Funny enough I have both of those drives installed, the 960 is the boot drive. Ran both the Samsung and CDM5 tests right after the update, iops on both read and writes we're down 100k and reads we're down, write mb's we're about the same, 1750MB on the 960 and 540MB on the 600p. There was a Windows update that installed after the bios update, the OS side of the bug patch, but to take a hit like that is huge. Boot time did slow a little also.

What values are you getting for iops and read/write speed?

thanks
