Hello friends! I bought a dual-band Intel 7260XMW card - 1200mbps. The next steps will be to flash the Bios, as described in the first post.
What are your observations about working dual-band cards on the y580, except 6205
?
My current bios is 5DCN40WW (V2.07)
Thanks!

Hi, I have a Y580 with the 8.01 modded bios.

 

I use a BCM4352 (Bcm94352hmb) wireless-ac card because it works in Windows, Linux and Hackintosh.

 

Main o/s is linux and it switches perfectly between low band and high band.

 

I used to use this with the 2.07 bios too, so I know it works with that version too.

 

This card has bluetooth 4.0 built in to it, but I could never get it to be recognised.  The bluetooth card inside the laptop is old and slow now, so I use a USB BT 4.2 dongle for BT.  Maybe there are other wifi cards that are dual-band where the BT is recognised by the Y580 - if so, let me know!

 

Good luck

How you get that lowest temperature on Y580 in this frequency? 
I read in internet 1000 mhz - 65 degrees or 1200 mhz and 70 degrees but in my laptop i have 1000mhz and around 80-85 degress.
What are you doing with your laptop for get this perfect result?

 

And second question.
How i can modify the ***.ROM file? I can`t find the program for open him. I want try change table voltage for frequency. My gpu get 1.125V when give 1000mhz and on 885mhz give 1.05V. I want try set 1V for 885mhz and 1.05V for 1000mhz. Maybe that are help me get lowest temperature =)

OR 
Process downvolting. Is`t real in this gpu and laptop?

      In this thread you can post your requests for Lenovo G500 and G400 bios unlock.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
       
      For prepare unlocked bios you should post your request here and then send me your file backup of bios via PM or upload it into any fileserver and send me the link.  For creating backup of bios use attached utility. Extract attached archive directly on the Desktop and run utility as Administrator (right click mouse, choice "Run as Administrator). Utility will create archive "results" directly on the Desktop. Send me this archive "results" via PM or upload it into any fileserver and send me the link.

      Hello, 
       
      some of my computer specs are as follows: 
      CPU: I9-9900k
      GPU: RTX 2070
      memory: 32 GB (forget the manufacturer/ clocks)
      Dsanke bios mod
       
       
       I recently bought a 1440p screen that is 120hz capable, but it does not allow me to select the 120hz option. I have checked numerous places and all of the websites say that this screen is 120hz enabled. I have the dsanke bios mod on my computer. I see people being able to use this screen's 120hz functionality, but I can't get it to work. Any suggestions? If you need any additional information about my laptop, I will be happy to provide info.
