Lenovo Y400 / Y500 - unlocked BIOS / wlan whitelist mod

Recommended Posts

New unlocked vbios for sli 650M ultrabay card.

And for sli 750M ultrabay card.

Hi,

Thanks for the updated vbios!

Unfortunately, on my system, the 750M appears not to be unlocked (still the +135 MHz GPU speed limit applies).

The flashing went fine (I ignored the message about wrong PCI subsystem, and flashed with nvflash -i1 -r, followed by nvflash -i1 -6 newrom.rom).

Could you have a look at that please?

Thanks and greetings,

Auke Nauta

The updated vbios worked great!! Can we get an overvolt version? Also, I've noticed that my benchmarks have gone up significantly since Windows 8.1... Noticed the boost even at stock speeds but now that both cards are overclocked, the scores are amazing. NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3632QM,LENOVO INVALID right off the bat it is 200 points higher than when I was running at 1200/2500 mhz. Games are silky smooth too, so it is not just the benchmarks. I'm impressed that after a year of owning this thing, it is still getting better. I'm also scoring 560ish in Heaven, before I could barely break into the 500's.

Nice! So you're getting higher benchmark scores even with lower clocks? What were your clock speeds in the 3DMark 11 and Heaven tests here? Also, what driver version?

Thanks @n1smo. Good to see you back. :47_002:

Ok. This is mod with stock frequency.

Klem and for 750m GPU please. I think there may present the same problem

Place here your screenshot GPU-Z and Nvidia Inspector from your ultrabay card after flashing mod bios.

@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.

You don't understand me. I have a laptop with 2x650m GPU. but I thought that with the GPU 750 may be the same problem

That is some serious tunning you did there :D

LOL, definitely not intentional but yeah... it's a touch screen too, so I guess you can say it is an improvement. Definitely took the mobility out of it.... oh well. I'll probably buy a Y500 off of EBay one of these days so I can troubleshoot.

So you've been away since your display issue cropped up? I remember that was a while ago. Why not get Lenovo to fix or replace it for you?

HAHAHA.. yeah, I've been away for that long... Man, that was probably close to 6 months ago. But I accept full responsibility for my actions (which was overvolting/overclocking too much) and I'll deal with it. Not going to go through Lenovo because I hate them and they can go eat a _____. Still not over the keyboard/ touchpad issues (even though I've fixed it a long time ago), not to mention their false advertising, ie. WiDi. My next laptop will probably be an Alienware, Asus or MSI. I was pretty close to getting an Alienware, but I really have no need for a laptop right now and the Y500 is still more than relevant. May change my mind when GTA V comes out, we'll see.... or I may just get a PS4.... ;)

My processor on y500 keeps on crazily over clocking and under clocking it self, it would jump from 1.1 ghz to 3.1 ghz on idle for no reason, would flashing the bios fix that?

And for sli 750M ultrabay card.

@Klem Nice stuff, thanks! I was able to run the second GPU OC'd to 250MHz, but past that (at least in Bioshock Infinite benchmark) stuff crashes. I notice that voltages for my internal GPU run higher because of unlocked voltage offset, so I guess I would be able to push to +400MHz for second GPU if voltage was unlocked here too. Please unlock this or set it to +200mV like I have for my internal GPU!

This is pretty frustrating.

I have tried both og Klem´s uploaded bios and I am still only able to OC the ultrabay with 135MHZ...

My main card was flashed succesfully the fist time i tried but the ultrabay still eludes me.

I am sure I am doing everything correctly, can you guys see what the problem might be?

When you flashed videobios correctly you will see in the window Nvidia Inspector in right side of the number BIOS, inscription "modified".

Ok, i used the last bios you uploaded and used the flashing codes provided in the OP.

Can we agree the ultrabay is GPU #1 when we flash?

What else could I have done wrong?

You can try reinstalling video driver. I had the same issue.

Thanks Satenex, a restart cleared it right up.

a bit weird as I already restarted it when the flashing was done, but no worries, hopefully I will never have to do this again. ;)

How much will I be able to OC reliably without having to learn about voltage, repasting ect.?

I mainly use afterburner, so i am looking for a number like the +135MHZ number Im used to.

I'm tired of the bad wlan card and want to switch it by getting rid of the whitelist.

My BIOS version is 2.03, will it be safe to do this flash?

Also any downsides to doing this flash?

I have put Windows 7 on my computer instead of windows 8 is there a different installation method for Windows 7?

Any problems with this modded bios and windows 7?

and I have the 750m sli version if that matters.

I cant seem to create my backup. With the dos and 64 version when I click the backup.bat it opens a window and closes so fast I can't even see what it says.

If I try to use the provided command line (-d BackupBiosY500.bin -bios) I get error

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

I cannot launch the DOS application, windows alerts me saying "this application can not run on your system"

Am I just stupid and doing it wrong? haha.

      Hi folks,
        Greetings from Brazil!  Not sure I'm posting in the right place, but I have a question:  how do I find out the brand and model of my BIOS chip without having to open my laptop?  I can't find this information anywhere.  Been searching for days... I have a Lenovo Ideapad 300-15ISK 80RS (motherboard Paris 5A8).  Thanks a lot for your time and help! I really appreciate it!   Best regards,   JC.

      Well everyone...I have a confession to make-I flashed svl7 modified 970m vbios before I wiped my drivers! Everything seemed to run fine, I could game but noticed my clocks fluctuating a bit crazy. Figured I'd try a OC profile in afterburner while running a 27 27 26 26 clock in TS a bit stupid I know. Well 3d mark froze so I did a reboot...Black Screen on startup I heard windows boot so I feared I bricked my card. Tried external monitor..works fine. This is where my stupidity really hit the cosmos. I had another m15x 900p LCD laying around plugged that in. Worked fine back too overclocking bro! Well same thing happened. My profile was not overly crazy as I can remember. But I bricked another screen. Plugged in external monitor everything fine. I was using latest nvidia drivers 436.48 I believe. So I wiped drivers using DDU. Reflashed to stock clevo bios. Tried both LCD again still nothing. Installed old 7970m still nothing. Cleared CMos again nope. Reinstalled 970m with svl7 vbios with newest driver and been gaming on my external monitor. Have done some OC with inspector. Everything seems to work as it should. Temps and performance are great. Did I brick my monitors??? Never heard of this problem.
