Lenovo Y410p / Y510p - unlocked BIOS / wlan whitelist mod / vbios mod

Recommended Posts

Hello everyone :)

Forgive me for the noob question as I am new here. I recently got a GT750M for my y510p ultrabay. The official BIOS flash from Lenovo doesn't work and I refuse to go back to Windows 8. Does this mod allow me to have SLI on Windows 7? Thank you

vBIOS update not required for SLI in Windows 7.

But I still need to flash the ultrabay, right? My laptop isn't recognizing the second GPU and Lenovo doesn't provide support for windows 7

No you do not. If you want to overclock and overvolt you can still flash it, but not mandatory for functioning SLI in Windows 7 unlike Windows 8. If Windows doesn't recognize GPU it is a different issue. Maybe check that card shows up in Device Manager and SLI is enabled in Nvidia Control Panel.

Lenovo provides official Windows 7 drivers on its site but ofc downloading latest versions from manufacturers' websites is recommended.

unfortunately, there is no second nvidia driver provided by lenovo for windows 7, i already try install second video driver for windows 8 & 8.1 at windows 7, but not work, nvidia wont detect the 2nd GPU.

Hello, guys. I have a y510p and intend to try this bios mod. One question tho - does the vbios for the second 750M give a performance increase by itself or do i have to work the clocks from the bios?

Could anyone kindly please make a list of the BIOS settings which do not work, or which brick/fry the notebook? I've read through a few pages and seen that volting and clocking may do this to the notebook, but does shutting a couple of cores off do the same? Also, is that option even there? And, finally, does the BIOS have the option to switch to the IGPU whilst both the discrete cards are inserted? Just want to get all my lists checked and see if the modded BIOS would actually help me do any further power saving or not. :(

Hey guy, I think, I've found option in bios that stop cpu from throttling when gpu temp reach 65 degrees. It's ACPI 5.0 CPPC Support and ACPI 5.0 CPPC Platform SCI in Advanced CPU Control under Power tab in Modded Bios. I heard it was cpu powersaving feature in Haswell so I enabled them and install this driver (Intel Collaborative Processor Performance Control (CPPC) Driver for Windows 8.1 (64-bit), 8 (64-bit) - ThinkPad - Lenovo Support (US)).

Then today I ran Heaven Benchmark and gpu temp had gone high(75 degrees and 85 degrees) but to my surprise I monitor my cpu using XTU and saw that cpu still turbo boosting and doesn't throttle.

About the CPU performance: When driver was installed there is new option in windows power option called Intel CPPC Energy Efficiency Settings. You can enable or disable it (Default are "Enabled" on battery and "Disabled" when plugged in). I leave it at default setting.

I apologize if this is a stupid question, but I am new to these mods. If I flash my BIOS in order to install an intel 7260, will this affect me in any way other than the warranty?

I am going to flash modified bios to test it out. So now we can disable throttling semi-official way :D.

Hi, I've buy a Y510p with a single GT750M GPU, and I've brought a GT 750M5. But I'm getting the message "unauthorized slave vga card is plugged in. power off and remove it". Will this version fix my issue? Best Regards

Whats the version of original unmodified version of your bios? If you have old bios try to download official bios update from Lenovo and also download vga bios update from this thread. Its second post. Make sure you pick 750m bios. Just follow the instructions.

If it will fix your issue I dont know but you can try. Where did you bought your laptop and second vga card?

Thats the official fix from lenovo as I said before, you have to have updated bios and also vga bios. You can download original bios from the link above.

If non above worked try modified bios. And if it still dont work then speak to Lenovo technical support and ask them for help.

I brought this computer at Ebay. Work wonderful with a single GT 750M, but I've brought another GT750M5 separately, computer has Bios 3.05 but it display that message when I replace the original optical drive with the gpu. I have contacted Lenovo support but they don't want to help me as my warranty expired 2 months ago. Computer won't boot with the second gpu, so the problem is not that videocard is not recognized by windows, the problem is that the computer stops booting and display this message.

Sorry, but I can't seem to get Step 1 to work. The backup.bat file run in Admin Cmd prompt doesn't spit out a bios back up anywhere that I can see. Is there an alternative to this step?

OK I managed to get to the dragging and dropping a backup bios into the biosfixer, but ended up with this:

"Input file: bios.bin

ERROR - invalid input file. Make sure it's a proper dump of BIOS version v1.07, v1.09 or v1.10"

I didn't run anything with admin prompt or admin priveleges because when I did, nothing happened. No backup bios was created and the biosfixer with admin priveleges wouldn't let me drag any files onto it.

Did you tried modified bios aswell? Well you have bought non-sli version then probably. They should at least tell you if its going to work or not. Cheeky bastards those lenovo technicians.

If modified bios is not going to work then you might be out of luck. I bought 755M SLI version . I was in temtation to buy it separately but I was lucky that I spotted great deal on this model in my country so I bought it cheaper than lenovo sells it. It was however DOS version but I can install clean windows myself without any crappy preinstalled software as manufacturers do them.

If you really have non-sli version then you are out of luck as non-sli versions are probably not able to deliver enough power for second ultrabay vga. Even if you have got 170W power adapter. Sorry but you better sell that laptop and that card for whatever you can and buy SLI version with ultrabay card.

Nevermind I figured it out. Bios modded successfully, but just discovered that the Intel 7260 wireless-n chip I ordered is a DoA... effing Murphy's law.

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.
