Lenovo Y580 / Y480 'unlocked' BIOS versions

Recommended Posts

Go to your bios, it's written there. Press win+r -> dxdiag. This should display the bios version as well.

Hi, is the V8.01 is the true full flash or it is only the partial flash? Partial flash as in it will flash but will return me with an error that a portion of memory could not be written to.

LOL, ok... so after bricking this bad boy I just got my laptop fixed and returned back from Lenovo.

From Windows 8 X64 running DX Diagnostic tool, it says I have version

InsydeH20 Version 03.71.515DCN40WW (V2.07)

I downloaded [Y580][Y480]-'unlocked_BIOS'_660mGHzEdition_WhitelistMod, extracted it, and ran InsydeFlash.exe as admin and I receive the following error.

"The version of the rom file isn't newer than version of bios."

I hit OK and the program closes.

Now what?

Thanks for all your help thus far svl7. I'm a noob lol =)

Damn, forgot to change this... you'll need to modifiy the platform file, first line in the 'common flash' section -> change RESSEN to RESSDIS and try again.

nevermind, found this.

So it worked! Sweet. With the flash I did this does the 660M overclock right? Is there anything else I need to do?

Thanks so much!

Thanks so much!

yes, the 660m is on 1ghz default 3d clock. the only thing you need to do, is to change the ''lenovo energy management'' to ''dynamic graphics''. then the 660m runs at 1ghz.

Is it possible to change the core Voltage, e.g. undervolt the CPU?

And do i understnd it correctly, that the 1Ghz for the 660 aren't enabled by default? Because i just want to undervolt the CPU for now :)

Could be overheating, check your temps and make sure you are not blocking the vents.

Ah crap, I messed up the naming scheme... v8.00 is 5DCN89WW, I mistakenly labelled it as 5DCN90WW... So yes, if you have v8.00 you can safely use my (slightly mislabeled) mod (v8.00 in your case).

I have the 5DCN90WW on my laptop. Does this mean the mod you posted wont work for my laptop?

Thanks.

It will work, just use v8.01 (the 'real' 5DCN90WW).

Correct labels:

5DCN89WW - v8.00

5DCN90WW - v8.01

Can't wait to try it this weekend! Anyone can vouch for gaming performance increase with this BIOS?!

I don't have any concrete numbers for the increase, but I was able to overclock my GTX 660M to 1200MHZ core and 3600MHZ on the memory.

That's enough for a bump in graphic options for most games to run in 1080P.

My mistake... ;)

I was thinking of my desktop GTX 670.

I was able to clock the memory on the GTX 660M to 2900MHZ. :)

Hello everyone,

I am very new to flashing/bios/overclocking limits.

I have a Lenovo Y580 Model 209942U

I have attached pictures of my current GPU and DXDIAG (it has the latest nvidia drivers). If i am correct, when I flash, I will be using my DXDIAG which shows 03.71.515DCN38WW(V.205).

I never flashed a bios before.. Can someone please show me step by step without bricking my laptop. I really want to stable MHZ on both and I have a aftermarket laptop cooler as well. I normally use EVGA or nvidia inspector with 1085mhz core and 2800 mhz memory.

Can anyone please help? :) I will be very grateful!!

sv17 Please kind sir help me out. I don't know much about flashing. I don't have a usb drive so I will have to get one right? When I flash i'll be flashin in the windows and not the F2 setup>

I am more then willing to buy you a round of beers if I can get this done )=.

"I have attached pictures of my current GPU and DXDIAG (it has the latest nvidia drivers). If i am correct, when I flash, I will be using my DXDIAG which shows 03.71.515DCN38WW(V.205)"

I will be using the 2.0 method not the 8.01 right?

Do u recommend me to update my bios on lenovo's website then flash with your with mod or can i direct use your 2.0 mod?

Svl7 you have no idea how happy i will be once I finally get to flash my bios with your mod.

Kindest Regards,

Brian

      i want to ask two favours and a question from this community ..
       
      1.) Can someone mod my 940 mx to increase the target temperature and allow higher overclocking than 135hzband voltage control
       
      2.) Allowing my i5 7200U to be undervolted to reduce overall heat 
       
      The question : I repasted my gpu and cpu cleaned it thoroughly, made sure twice everything is connected properly, use a cooling pad and yet the upper portion of my chasis above f1-f12 keys is so hot that i can roast peanuts on it. 
       
      (if i left out any info or missed something please reply i would really love to have a page that has everything for people who have this laptop specifically for light gaming.)
