Does one have the vbios for 2nd GPU 650M that has the same clocks as the 1st GPU?

Klem modified it long time ago but it does not seem to show up in his post anymore.

I never had problems with the Lenovo energy management. Not even on the Windows 10 preview builds.

This happens when laptop is plugged-in and put on power saving scenario.

Go for crucial memory. Their site is dedicated for RAM upgrades and quality is good.

I am starting to have no clue what is happening to your GPU.

You can try to install Win7 on a different partition and update the vBIOS from there.

One question, why don't you use the official way if this way doesn't work for you?

Go to support.lenovo.com: http://download.lenovo.com/consumer/mobiles/gt650m2ndvgay00.exe

Use the steps described by Lenovo: http://download.lenovo.com/consumer/mobiles/gt650m2ndvgay00.txt

@Klem don't miss inform him. That is an old topic that was solved.

I have Windows 8.1 PRO and I was one of the active users who pushed Lenovo and NVidia to find a solution. At some point Lenovo leaked the ROM before they officially uploaded on their website. I was able to update my vBIOS on the 2nd GPU.

I am currently on 8.1 with SLI on playing games like DotA2 or CS:GO.

@zencowboy007, give me a time frame on Friday, please specify the time zone also. I am on GMT+2 on Friday(Europe). Until then please upgrade to 2.04 BIOS.

There is no need for money, I am trying to help because I find it challenging.

If by some ends we manage to get through this you can donate to @svl7 who made all the tutorials that helped me to learn all this stuff.

I am pretty convinced is doable but somewhere somehow you are doing something wrong.

You can upgrade to 2.04 and then try again, else I don't know, maybe remote desktop connection

Hmm, let's rewind.

Please try to update using DOS mode.

Use these 2 files:

nvflash: https://dl.dropboxusercontent.com/u/35135276/NVFLASH/nvflash.exe

vbios.bat: https://dl.dropboxusercontent.com/u/35135276/NVFLASH/Vbios.bat

edit the bat file to reflect the name of your rom. or simple rename your rom file to match the one in the bat file.

Copy these 2 files on the stick.

Boot to DOS and run vbios.bat

The bat file has everything it needs to perform the update of the vbios.

Ofc is none. The 16GB RAM has benefits if you work on this laptop. I have 16GB RAM but I also run VMs images on it.

From my point of view, there are a lot of mistakes you did.

1. Always do it in DOS mode. It is better when upgrading firmware versions.

2. If not in DOS mode, be sure that you CMD is launched as an administrator (run as administrator). Doesn't matter if your account has local admin rights, it is not the same.

3. What does it say when you hit nvflash --protectoff? (I can't see because the windows are overlapping) . Run it again with cmd as administrator.

4. Don't use that version of nvflash, try with 5.128.

Advice for future use: don't place important files on desktop profile. Use a folder in a local partition, because how you have it now, makes everything to depend on your profile, every path needs to access your account.

Ofc, I have it. I have the modded bios and the card in my laptop.

What I did before placing it inside was uninstall the old wifi card, remove it from the laptop then inserted the new one and installed the drivers from intel downloadcenter.

What do you mean you took it off BIOS?

There are 2 ways:

1: The PXE boot needs to be disabled.

2: The boot devices order list.

Which one did you do?

huh? why are you searching the drivers on 7260 on Lenovo models?

You do realize that each of one us who has 7260 drivers, bought a 7260 wi-fi card and manually installed it physically in laptop, therefor the wi-fi card has nothing to do with Lenovo models. Nothing! It is a customization made by the user.

You do realize that you are answering to a thread that had the last reply 2 years ago..

Thanks, I'm currently trying to extract it from my bios before I mod it and of course back-up my 2.03. I'm using this program however as I stated before I am using Windows 7.

The programs I'm using for Windows Key Extraction are currently giving me only the Windows 7 key. Any help how to extract the Windows 8 key from my bios before I back it up and mod it.

Typo, sorry. Can't extract it*. You can't, cause it's not a key.

thanks, are you talking about the backup of my stock bios which has my win 8 license? Also is there a way to take the serial of the code for my win8 license from the stock bios? (I'll still back it up but would it be possible to get the serial from it?)

I'm waiting for 7260ac to come in before i do this mod, so i really want to make sure everything goes well and I have no trouble. Also is there a risk of bricking the system?

I've watched this tutorial BIOS v2.04MOD Tutorial-How to Flash Y400-500 2.02 to 2.04 on Vimeo several times to back up what svl7's instructions are.

You can extract the Windows 8 license, it's not a key, it's embedded for your hardware, that's why you have to make the back-up.

just to clarify I can mod my bios if i have Windows 7?

Modding the BIOS has nothing to do with your operation system. However, you should do the exact steps so that you don't lose your embedded Windows 8 license.

Shouldn't this be done from a bootable USB? Running in MS-DOS? I always flash the bios in MS-DOS and not from Windows directly.

Uninstall all drivers before inserting the card. Install the drivers that MS is recommending through Windows Update.

Does it really change the boot time? I've heard that most people say tha win 8 boots faster than win 7 but for me it's not the case, it really takes a long time, sometimes the login windows is fast but a full boot of the whole OS it really takes too much time and for that reason I try to keep in sleep mode rather than powering off my y400

That is because you are on Legacy in BIOS and not UEFI. Also you should enable Secure boot.

this is the downside of UEFI bios. It was announced long before that Linux installations on Windows machines with UEFI will be hard to do.

@octiceps, LOL, I had to walk away for a while like GSP after the display died. Still don't know what it is, if it's the screen, the video cable, or the motherboard but I'm thinking it's the motherboard..... So now I've permanently turned my laptop into a desktop. Took the entire lid assembly off.... But yes, it is benching higher running at 1127/2475 and 9.18.13.3182 drivers. I want to overvolt and run at 1200+ again to see what the scores will look like.

That is some serious tunning you did there

I flashed this bios too.

In this bios the ultrabay VGA has a different max clock then the integrated.

integrated Max 790Mhz boost 835Mhz, Ulrabay max 836, boost 836.

So when u overlock u need 46Mhz less in ultrabay card to get the same overlock speed in both card....

For example:

U like to overclock booth card core spped to 1000Mhz in Nvidia inspector u need set card 0 +210Mhz, card 1 +164Mhz.

PS:

I think wee need pm KLEM to change the 650M vbios core clock to default state...

You are correct.

in MSI Afterburner increases the frequency of the core 350mhz, memory clock +600mhz, when applying the load on the GPU (aida64) observe differences in the frequency of the core (1139mhz integrated and 1186mhz Ultrabay) in consequence of which the laptop starts to freezing, on the previous firmware this was not observed

Are you sure you have Y500 650M? I didn't had this problem. Maybe you flashed it wrong. I do it while I am boot mode, not directly from Windows.

See image below.
