Well, i was succesfull in flashing and unlocking the main card and the flashing of the ultrabay also went smooth but I am still not able to OC more than 135mhz on the ultrabay card.

I am pretty sure i did everything correctly and I didnt get any errors during the flash, sp do any of you guys know what I might have done wrong?

One quick question, how to enable wake on lan setting in this bios? I cant find any setting on this bios.

It's in the WiFi card properties in Device Manager, not in BIOS.

You didn't do anything wrong. We're waiting for the Ultrabay mod from svl7: http://forum.techinferno.com/general-notebook-discussions/4635-bios-vbios-modification-request-thread-svl7-6.html#post72163

still no modded vBios for the ultra bay in windows 8.1. Hopefully soon! You did everything correctly just the vBios thats compatible with 8.1 and the latest nVidia drivers has not been modded and only the default overclock is available.

If someone wants videobios with increasing core frequency or memory frequency or some increasing voltage, please contact me in PM.

thanks for the help klem. much appreciated! any chance you could get a voltage mod in there too? as of now i can only change core and memory clock speeds, maybe i did something wrong?

I use +311Mhz for the core and +250Mhz for the memory with stock voltage. Anyway while in game, both cards know to change the voltage to fit the need.

I want to push past stock voltage so that it runs with more stability.Using your clocks I'm still getting crashes in BF4 (yes I know this game crashes all the time as is)

@mackhunse well as you said, it may be the game. I admit that I don't play a lot of games, but I used these numbers for over 6 months while playing dota2. Each time the chart in nVidiaInspector reaches the designed OC limit, so the game pushes the gpu's at max.

What I am trying to say is that I OC-ed and both cards ran ok, no crashes with stock voltage and the temperatures went as high as 72 degrees Celsius.

Also BF4 has a lot of issues going on with NVidia drivers, I see like 100 of users bashing the GeForce forums because of this.

Is anyone experiencing SLI problems with Need for speed Rivals ? I can't get the second 650M working.

New unlocked vbios for sli 650M ultrabay card.

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.

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...

Yep this messes things up when you overclock using MSI Afterburner since you can't adjust the GPU's individually like you can in Nvidia Inspector.

      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.
