sli is #0

but ive got an error

ERROR: Software write protection enabled, unable to erase EEPROM.

nvflash -r

or

nvflash --protectoff doesnt help

still core clock doesnt rise..

ive created backup in nvflash than

nvflash -i[1] -6 vbios2.rom

and it was written smth like comparing cards..and no any process/comlete info..trided several times but result is the same.Maybe sli card has #0?both cards have the same names.I didnt risked to try flash another card

The vbios is fine, but it lacks the uefi part (which doesn't really matter, but I wonder whether SLI would work like this with an uefi installation and fast boot / secure boot activated).

The warning message when flashing doesn't matter, the IDs don't match, but it will work anyways.

For mobile systems I still recommend flashing per DOS version of nvflash, if the Win version works, the other should as well.

if i'll flash with this file sli overclock will be avalable?

and how to flash?The same way like in instruction but at the last step choose this file?

sorry for stupid questions..

i have v2.02 flashed

I already probably bothered you, I won't disturb any more... can itself somehow I will understand the matter is that I not so understand in all these computer affairs, I only study...

Then run fpt manually in a admin command prompt with these parameters: -d bios.bin -bios

"-d" isn't the internal or external team executed by the program or the package file

You simply run the backup.bat as admin, this will create a backup of your bios.

Some badly designed anti-virus software block the PCIe driver, so you might need to temporarily disable the protection.

and how to learn, what Bios is successfully copied? I disconnected avast antivirus, but all the same it turns out nothing ((

I start backup.bat with the rights of the administrator, to a fraction of a second there is a window, and occurs nothing, and has to be and where then Bios copy has to lie?

and what you will advise to make?

Error 200: Invalid parameter value specified by user. Use -? option to see help.

what does this mistake mean? I can't make a nickname the copy Bios

it turns out nothing, I am very afflicted! ! ! !

svl7 by means of what program, it is necessary to do Bios copy? and how to start it? I have problems with transfer a post 1

You only need 5 posts to download files on here.

This BIOS mod removes the hardware whitelist which allows you to use third-party WiFi cards, which are blocked on the stock BIOS. Also, it shows a bunch of advanced BIOS settings that were hidden before. Lastly, it mods the vBIOS of the internal GT 650M GPU so that the artificial +135 MHz overclocking limit on the core is unlocked. However, if you are using SLI, it won't mod the vBIOS of the Ultrabay GPU and that looks to be unsolvable for the foreseeable future.

Thanks for the info. Man that sucks. The Ultrabay GPU is basically limiting the performance of main GPU then. The core on this GPU can go so much higher than +135 MHz.

thanks for answers. I have too a konfiguryation SLI

I already downloaded everything, but I can't understand as with it to work how to make the copy Bios? I Russian, and stir a language barrier a little... maybe you will help screenshots?

I'm bumping this up for all those people asking questions about modding their particular BIOS version.

For everyone who owns a Y400/Y500 and wants a modded BIOS and vBIOS, regardless of whatever version modded or unmodded you're currently on:

First go to here and download the latest official Lenovo BIOS update which is 6BCN42WW(V2.02). Even though it's from Baidu (AKA Chinese Google) I have scanned it with multiple malware scanners and it checks out.

Then, run the .exe and it will restart your PC and flash your BIOS to V2.02 unmodded. It will also reset any BIOS changes you made previously, but don't change them back yet.

Now, follow svl7's instruction in the OP and use his modded V2.02 BIOS I've attached.

Once that's finished flashing you can change all the BIOS options to what you had before.

I was able to use these steps to flash my modded V1.05 BIOS to modded V2.02.

Svl7, if you want to update the OP with this information, I think it will help a lot of people asking to get their particular revision modded.

I already have Bios 2.02 but while I can't download anything from this site yet... and one more small question, what opportunities opens modified Bios 2.02?

You need to use a modded BIOS because the vBIOS is part of the BIOS on this system.

Or you can use the Nvidia Inspector and .bat files method.

many thanks for the answer, instead of you, what such could explain me a.bat files method and how to use it?

svl7, explain to me please, what on Y500 to lift gt650 frequencies, modified Bios or vbios is necessary?

Only flash a mod of the same version as you're using. If you want to go 2.02 then use the leaked stock update linked above, and once you done this flash the mod according to the instructions. Whatever you do, don't flash a mod of a different version than the one on your system.

Read the instructions and your Win8 cert and activation will be fine.

I have Bios 2.02, sli... whether yours will work fashions? I here read that fashions not the worker for sli

who has an image Bios 1.05, want to return to it what to try modbios 1.05?

I have Bios 2.02, sli... whether yours will work fashions? I here read that fashions not the worker for sli
