    UPDATE: ALL DOWNLOADS LISTED IN THIS POST FOUND HERE. Nvidia 'Kepler' GPUs - modified VBIOS files >>> NOTE: More versions (including voltage mods) exclusive for T|I users can be found in the second post. <<< The 'Kepler' GPUs from Nvidia perform really well, even at increased clocks speeds they stay quite cool - a perfect behavior when it comes to overclocking and improving the performance. Unfortunately the mobile GPUs suffer from an artificial +135MHz core overclocking limit, so you can't go higher by using tools like Nvidia Inspector and similar. The modified VBIOS files listed here have this limit unlocked, some have increased stock clocks or tweaked voltages. Just refer to the description.

    In case you own a Lenovo Y410p or Y510p laptop, you might be interested in upgrading its performance by installing an external graphics card. Ultrabay eGPU adapter designed by @gerald was proven to be a convenient plug-and-play option to do exactly that. However, for a long time only an AMD-branded GPUs could be used due to limitations in the Lenovo's stock BIOS. The purpose of the modified firmware presented here is to expand the range of available GPUs by enabling Nvidia support on Gerald's Ultrabay eGPU adapter. Huge thanks to: @MWichni - For efficiently assisting me during the development of this mod. By flashing dozens of BIOS builds over the course of several weeks and thoroughly describing the effects observed (or the lack thereof), he enabled me to fully understand necessary parts in BIOS structure and come up with a final solution. @svl7 - Whose unlocked BIOS / Whitelist mod has served as a basis for this modification. His discovery of a security hole in V2.07 BIOS has provided us with a convenient BIOS flashing method that does not require a physical programmer. The Unlocked BIOS and WLAN whitelist mods originally designed by him are also implemented in this BIOS mod. @gerald - For designing the aforementioned adapter. Without it, all this work would make very little sense. Key features: Resolves the "40-second reboot" issue normally encountered while using Nvidia graphics cards with Ultrabay eGPU adapter, thus allowing all Nvidia cards to be used. Based on the latest V3.08 BIOS. Includes Svl7's WLAN whitelist removal mod - for the convenience of aftermarket WLAN card users. Includes Svl7's BIOS debug menu mod - for the ease of experimentation with newly available features, e.g. attempting to use Nvidia Optimus to pass eGPU video back to laptop's display. NB! Svl7's Debug Menu is not a toy! It contains a lot of options that are either not supported or partially supported by the hardware platform and/or can disturb its normal operation or prevent the PC from booting up at all. Any of the entries not originally present in the stock BIOS should be modified at your own risk! DISCLAIMER: ANY MODIFICATIONS YOU ARE APPLYING TO YOUR HARDWARE ARE PERFORMED AT YOUR OWN RISK! AUTHOR OF THIS MOD DOES NOT HOLD ANY LIABILITY FOR LOSS OR DAMAGE RELATED TO USING THIS SOFTWARE. Screenshots: Installation instructions: If things don't go right: Error 43: If you intend using the GTX10XX-series Nvidia card as the eGPU (which you probably do), you are very likely to encounter the infamous Error 43 in Windows Device Manager. This is a widely known issue in the eGPU community and is not related to this particular mod in any way. Following this guide thoroughly will in most cases resolve the Error 43 issue. Download: Get your copy here! P.S.: Version of this mod for Lenovo Y400/Y500 models is coming soon!

    Are you stay forever on laptop? You can go another way - get GPU for you desktop. It will work in adapter too, but you don't need to sell it later. Just transfer in desktop. Also, on one Russian site was nice review of HL:A and 20 GPUs in VR. You may look table at the end. Here is link: https://3dnews.ru/1010227

    Hi! Ok. Send me your file backup of bios. For creating backup of bios use attached utility. Extract attached archive directly on the Desktop and run backup tool as Administrator (right click mouse). Utility will create archive "results" directly on the Desktop. Post here or send me this archive "results" via PM, or upload it into any fileserver and send me the link. https://www.sendspace.com/file/58n0wm

    Hi! To reduce your temp, just disasembly laptop and change termal paste on CPU and GPU, and also clean fans from the dust. Unlocked vbios can't help you with undervolting and can't reduce GPU temp. Unlocked vbios can help you to overclock your graphic card, which on the contrary will increase the GPU temp.

    1. Completely uninstall MSI Afterburner with all settings. Reboot laptop. 2. Search in Google and download DDU utility. Run it and completely uninstall all Nvidia drivers (in Safe Mode). Reboot laptop. 3. Download and install new Nvidia drivers with enabled option "Clean Install". Then run any 3D load in window mode, and in same time run Nvidia Inspector utility, and check if you core and memory clock will increase.

    Luckily I haven't had to do many vBIOS flashes in my lifetime but this means that I have very little experience. A bad or incorrect flash can brick your card so I'd hate to give you the wrong information. There aren't a lot of active Alienware guys on here anymore so your best bet would be NotebookReview. I would say that a Dell vBIOS would be a good one but you will have to work out if it's a g-sync or non g-sync card as you'll need to make sure you don't flash the wrong vBIOS. I believe the 1BA1 card is non g-sync. If you install the card in your machine you can check your hardware ID in Device Manager before installing a driver and it should tell you which one your have. GPU-Z should also tell you. EDIT: When I got my 1070 for my M18x I had all kinds of issues until I realised that someone had flashed a g-sync vBIOS on my non g-sync card. Luckily a Dell non g-sync vBIOS solved the problem for me.

    For sure this new driver is really working great! I've only encounter one or two minor bugs here and there. Where my games have just suddenly crashed without an error or anything...generally within the first 20 minutes. However as the driver seeds itself into position and after an initial 24 hour burn in test with multiple games ranging from For Honor, World of warcraft to Call of duty Modern warfare Multiplayer/Battle Royale mode(Super Memory intensive). My 880m is absolutely shredding through these. It makes me squeal in delight tbh. For this I can not thank you enough and I can not wait to see your how-to video and will be sure to give it plenty of rates up!

    Is there a specific reason why the integrated graphics card is disabled on P7xxTM1? My machine learning laptop has that motherboard and I would like to enable the integrated Intel GPU in it (in addition to the dedicated Nvidia GPU that's present in the system).

    I have to give my review from someone very inexperienced.. and say I will need some help to complete this flash to my y510p. I guess things went real smooth until I found out that the video was removed and I seemed unable to complete making a copy of my bios and drag/drop to place on my pen drive. I used rufus to make the boot drive but when I tried to flash the bios didn't stick but the ec did. I was able to boot back up and bring my bios back to 3.05. After running through the process again when I got to the point of taking the bios back to version 207(stock) I received a warning that my bios did not match?... Went to Lenovo to download and reinstall the bios(v3.05) but they have moved up to 3.08 now so I did not install it. Perhaps someone could tell me how to get back on track and be successful with this. My 7260 is burning a hole in the package it came in..... Below Is the final result of my pen drive contents......

    Thank you. Hello Klem thank you. This Bios is working. Thank you for add the UEFI modul to this bios. I hope when i switch to UEFI the UEFI modul is wirking too, but i will testing. Maybe can you help me with a other problem with this bios? This bios have 1 mini bug. This bios is complete unlocked for overclocking. This i think couse a problem when the Laptop is in battery mode. If the Laptop is in battery mode the GPU do not throtle down. Normaly the GPU on battery mode use P state 5 or 8 and dont use the highest P state 00. Can you have a second look to this bios maybe you have a idee to solve this? I hope you understand me. Sorry for my english.

    Hello techinferno community, I will show what overclocks i use and a few tips on how to overclock with other card you might have. This is for GTX 770m and with Bios Modded, Clevo/Sager laptop np8230 Before Overclock: Heaven Benchmark 4.0 Results: After Overclock: Heaven Benchmark 4.0 Results: Max Temp was 80C with Gpu Stress FurMark on my laptop, may vary. You can push it even further tho but il stay with these sets. I also notice that you need to have a distance between Core Clock and Voltage values, if you see in the pic, it was a 5 value, like core 1001 and voltage 1006 or any higher clock with that distance set, without this rule i would have FPS drops ingame. May vary with other GPU's and Games! Tips on overclocking GPU Memory clocks: You can push it until you reach the point where you don't get artifacts. Example if my stock is 4008 and i push it to 5192 but get artifacts sometimes or always, lower it by 5 and keep testing until you get it stable. Also you can't push it further by increasing voltage. Core Clock: You can push this one until a point where your screen won't freeze, to continue overclocking it you will need to increase your voltage. Take in mind that if you put too much voltage it will cause problems. I experienced FPS drops while playing, even if i stand stood ingame.

To allow others to help you, always include details information on your eGPU setup. Please use this template when posting. This is how to generate Diags file & include them in your post. ^top Why is my eGPU is not detected? Try any of these:- If running a mPCIe eGPU refer to [url]http://forum.techinferno.com/diy-e-gpu-projects/11393-mpcie-egpu-troubleshooting-steps.html#post149873[/url] Power ON notebook with eGPU already connected & already turn ON. Connect eGPU to notebook but not turn ON yet. Turn ON notebook & before windows loading press F8 to halt windows loading. Turn ON eGPU & continue boot into windows. Connect eGPU to notebook but not turn ON yet. Turn ON notebook. When you see "Starting Windows" screen & you see the four dots emerged to form windows logo, turn ON eGPU. PCIe power connector Make sure you plugged all PCIe power connector on the GPU with 6/8-pin PCIe power connector(s) from PSU. If GPU have two PCIe power connectors & you think connected only one 6/8-pin PCIe power connector is enough, you're totally wrong. Floppy power connector (PE4L/PE4H) Connect floppy power connector from PSU to floppy power header on PE4L/PE4H Jumper (PE4L) Check out jumper settings in the manual which available from here:- PE4L v1.5: [url=http://www.hwtools.net/Adapter/PE4L.html]PE4L ( PCIe passive adapter ver1.5 )[/url] PE4L v2.1: [url=http://www.hwtools.net/Adapter/PE4L%20V2.1.html]PE4L V2.1 ( PCIe Adapter )[/url] ^top Common >>> I have problems when running eGPU Setup 1.30. See eGPU Setup 1.30 troubleshooting. ^top My system just boots to a black screen / my system hangs or BSODs while booting up to Win7 If running a mPCIe eGPU refer to [url]http://forum.techinferno.com/diy-e-gpu-projects/11393-mpcie-egpu-troubleshooting-steps.html#post149873[/url] Poweroff your eGPU. Boot Win7. Standby (not hibernate) your system, poweron your eGPU, resume your system. ^top My eGPU worked, then stopped working all of a sudden First thing is check your mini HDMI cable. 2 users requiring a replacement US$6-shipped cable to restore functionality. NOTE: This solution only for PE4L v1.5 & PE4H v2.4. ^top My eGPU hangs, particularly when doing a lot of graphics processing If you are running a Gen2-capable system (2nd gen i-core or newer) but not using a Gen2 capable eGPU adapter (PE4L 2.1b or PE4C 3.0), then you'll need to downgrade your link to Gen1 to gain reliable operation using Setup 1.30 Check your PSU is delivering the required power OR swap with another more powerful PSU and test again. We've found cheap double-rail PSUs might not deliver enough power. Eg: a Shaw 680W PSU has a 12V/16A and 12V/15A rail. The latter rail was insufficient to power a GTX470 requiring 225W of power. Also refer to Panzer's fuse bypass on PE4H ^top I can't play any game or run any benchmark for more than a minute or two before a complete system lock up - "black screen" of death. Pretty much the same issue as for Q4. Likely the PE4H's fuse is kicking in upon detecting a very high load and shuts down the power to your eGPU. This will occur with any of the heavy duty gpus like a GTX465+ or GTX560+. The solution is to set the PE4H 2.4 fuse bypass jumper (near the floppy molex connector). Older PE4H can do Panzer's fuse bypass to accomplish the same thing. ^top [ATI] Device Manager lists my eGPU without any errors but has have no resources against it nor is any external LCD detected This is a problem seen with onboard HD3450+HD6850 setups. The solution being a unified driver for both cards as provided by the DNA modded ATI drivers. ^top I have a PE4L + DC adapter. The eGPU isn't detected/fan spins up fast. Set JP4 on the PE4L as described so it draws 3.3V from the expresscard or mPCIe slot. Can connect a USB cable b/w your notebook and the PE4L to provide additional 5V->3.3V (regulated) if you find it's still flakey. ^top My eGPU recognises the external monitor but when I make it the primary it doesn't "turn on" and I'm simply reverted back to my internal LCD If you see a brief flash on the external LCD then it could either be a faulty HDMI cable connected to the LCD or the PSU is insufficient to drive the eGPU to actually display something. I did encounter a intermittently faulty HDMI cause this problem. Also, Optimus drivers newer than 258.96 will cause this if using a DVI-to-VGA adapter. ^top Upon powering my eGPU, the fan on the eGPU just spins faster and the card isn't detected. This indicates the eGPU is either not on the PCI bus or isn't getting 3.3V. Try unplugging, replugging the mini HDMI cable (expresscard solution) or hotplugging the PM3N (mPCIe solution). If the card is still not detected then connect the setup to another system's expresscard slot. It may be either a faulty expresscard slot or mini HDMI cable. Worth testing the eGPU in a desktop system as well. ^top I have problems running an Nvidia eGPU with an internal NVidia dGPU (supplied by nlooije/Khenglish) The trick is to get both an NVIDIA dGPU and eGPU working work under the same driver. This method assumes that the eGPU is detected in the device manager. If any errors such as code 12 or 43 are present check the corresponding items in the Troubleshooting section. If using the PM3N and it is not detected then maybe the mPCIe port is whitelisted, use the Setup 1.30 to unwhitelist. Download the latest drivers from the NVidia website or from this post by Tech Inferno Fan. Once the eGPU is detected, windows will automatically search for drivers through windows update. Cancel the search, and let windows install the standard vga drivers. In the device manager, right-click uninstall the dGPU and eGPU NVidia drivers. Use CCleaner to search for any residual Nvidia driversoftware and delete further. Install the latest Nvidia drivers. If everything went correctly then the installation software should ask permission to install the drivers twice, once for every card. Reboot and cross fingers. ^top My mHDMI cable does not fit in my half-height PM3N mPCIe socket Newer systems have been reported to have half-height mPCIe socket which may be limited in space for inserting a mHDMI cable due to the rigid connector. DIY solution: It is possible to strip the rigid connector to give the cable more flexibility and make more efficient use of the space. Use a sharp knife to cut along the ridge of the connector; be careful near the cable itself as the wires there are not protected. Inside the connector the wires are protected by a thick layer of solid glue. non-DIY solution: no commercial products have been found to solve this problem. (supplied by beatTheRestrictions) ^top Why does my USB/network/sound not working when enable my eGPU in Win7? Likely a PCI contention issue. Recommend setting up Setup 1.30, configured with a pci.bat (resulting from PCI compaction on your primary GPU + eGPU) prior to chainloading Win7. ^top Error 12 >>> My eGPU is detected and drivers loaded but has an error 12: cannot allocate resources against it in Device Manager Please check TOLUD on your notebook. For a reference on how to do this, please go to Pre-Purchase FAQ #2 (>> 2. How can I check if my notebook is compatible with an eGPU?). Many notebook vendors' bios were never designed to accomodate a desktop eGPU so do not setup PCI configuration space correctly to accomodate it resulting in the symptoms below. This will affect the DIY, Villagetronic ViDock and MSI Graphics Upgrade Solution (GUS) external graphics solutions. Symptom RequirementSIZE> Details with solution1SIZE> Device Manager error 12: cannot allocate resources Fix error Problem explanation: Windows XP/Server 2003 do not reconfigure the bridge windows based on the requirements of a device behind the bridge. This leads to a classic problem where a PCI device cannot be started due to lack of resources on the bridge, even though enough device resources are available to the system. For reasons such as this, a platform configuration that configures PCI devices at boot time works best. Some systems with more than 2.5GB RAM have no bios allocated free 256MB PCI window to host the desktop eGPU. Need to configure this correctly using one of the methods below: Solution#1 : (Update 3-14-2012) A DSDT override extending the root bridge into 36-bit can allow ALL systems with a 64-bit CPU and chipset (anything after 2007) to be eGPU compatible when used with Windows 7 and the latest iGPU/dGPU/eGPU drivers with up to 48GB of RAM installed. Solution#2 : Use Win8.x (WDM 1.2) that allows the primary video device to be disabled, freeing up resources for the eGPU to use. Solution#3 : Use Win7 to do a PCI relocation as described. Solution#4 : Use eGPU Setup 1.30 PCI Compaction. Solution#5 : [XP or Win7_with_XP_drivers] - disable onboard graphics using eGPU Setup 1.30 Solution#6 : install only 2.5GB/3GB of RAM, freeing 256MB of PCI Resource space. Solution#7 : Use Magma ExpressBox Full Driver described here. Greater than 2.5/3GB RAM installed Examples Neither the DV2000 or the 2510P had an appropriate PCI bridge memory window defined by the bios. The DV2000 too didn't have a free 256MB window when equipped with 3GB of RAM, the 2510P didn't have it's bridge correctly configured. In both cases eGPU Setup 1.30 was used to configure the PCI space correctly. ^top Even after successful compaction I still get a error 12: cannot allocate resources in Device Manager (Source: Tech Inferno Fan) The first thing to try is 32bitA compaction and see if that resolves it. If not, then what has been discovered happening is the I/O port allocated by compact gets moved by Win7. The I/O port allocated is shown as the last two echo lines in pci.bat such as : @echo -s 2:0.0 BASE_ADDRESS_5=2001 >> setpci.arg @echo -s 0:1c.1 1c.b=20 1d.b=20 >> setpci.arg The 0:1c.1 refers to pci-e port2 and the 2:0.0 refers to the PCI ID my GTX460 has. The 20 and 2001 means assign the port and GTX460 to use I/O port 0x2000-20FF. On this particular system, Win7 moves the pci-e express port2's I/O space to 0xD000-DFFF port instead which is odd so the GTX460 flags an error 12 since it can't get 0x2000-20ff. So the workaround is to change the 20 to be D0 and let Win7 have it's way. This can be done by adding two additional lines between "call pci" and "call chainload" to override compact's allocation. This setting will override any further re-runs of compaction as well. It should look like this in STARTUP.BAT file:- call pci setpci -s 2:0.0 BASE_ADDRESS_5=d001 setpci -s 0:1c.1 1c.b=d0 1d.b=d0 call chainload mbr ^top Error 42 >>> I get an error 42: cannot start device in Win7 Standby (not hibernate) your system, poweroff your eGPU, poweron, resume your system. ^top Error 43 >>> I get an error 43 against my eGPU in Win7. UPDATE: Use NVidia Verde 270.61 driver as described. First thing to replace is the mini HDMI cable. Could also be a faulty eGPU. Or if using a NVidia eGPU try: Ensure your PE4L 1.5+ or PE4H 2.4+ has the PCI Reset Delay slider set to 0s rather than 7 or 15. If it's the latter then upon doing a resume-from-standby the card will be delayed leading to an 'unconfigured' state, hence the error 43. Use Setup 1.30 to load a PCI dump AND use the 258.96 Optimus drivers (becak) Downgrade to 258.96 Optimus drivers (apollo-fox) (Update 26 July 2011) There is the Video cards->Initialize and Video cards->Save/Load dump features to eradicate error43. Ensure you are running the latest 275.33 Verde drivers + modded nvam.inf and the PCI reset delay slider on the PE4L 1.5/PE4H 2.4 is set to the 0 seconds position (not 7 or 15 seconds). Then proceed as follows: Boot eGPU Setup 1.30 with 2GB installed, run Setup 1.30, select to Video Cards->Save. If you are hotplugging after bios boot then need to select Video Cards->Save(Win) and follow instructions generated from within Windows. Install 4GB of RAM. Boot Windows. Create a devcon with 4GB of system RAM installed: eGPUeGPU-setup-mount v:devconmkdevcon Boot eGPU Setup 1.30, - select Video cards->Load to load the PCI space dump created when it was working with no error 43. - perform 32-bit PCI compaction on the iGPU+eGPU. - select startup.bat->edit, remove the 'call vidinit' since it might interfere with your load dump. - select Apply config.Run startup.bat - select Chainload mbr If still get an error 43, then repeat steps in (3) above but use 32-bitA PCI compaction method instead. ^top Optimus Setup: x1.1Opt/x1.2Opt >>> Lenovo Thinkpad/Dell Latitude: I boot with the expresscard in my system. The internal LCD doesn't appear/work. Neither do I see x1.Opt performance (NVidia) These system's bios will use the eGPU as the primary video if it detects it on bios startup. That means the iGPU will be disengaged. Problem then is the internal LCD won't work and neither will x1.Opt since they are both reliant on a iGPU to be the primary video card. Solution is to boot past the bios with the eGPU switched off, then either: hotplug the EC2C by hitting F8 to stall the Windows boot proces power on eGPU, resume in Windows boot Setup 1.30 and hotplug if need PCI compaction ^top Installing Nvidia drivers with AMD/Intel switchable graphics gives an error (supplied by appolo-fox) Installing Nvidia drivers with AMD/Intel switchable graphics may give you an error asking you to install Intel drivers first. Solution is to uninstall the switchable driver from your manufacturer (Lenovo in this case); system should revert to pure Intel driver via WinUpdate (if not, you will need to reboot and disable AMD discrete GPU with Setup 1.30 and let WinUpdate install or download newest Intel driver from their website. The Nvidia installer should be content with the pure Intel driver and install correctly. After Nvidia installation, reinstall your switchable graphics driver. [URL=http://imageshack.us/photo/my-images/811/amdintel.jpg/] [/URL] -> Intel driver provided by ATI (AMD). Nvidia installer exits with error. ^top I can't get internal LCD mode to work. This appears to be the case if you attach your eGPU after Win7 boots. So either hotplug your eGPU at the Win7 bootloader menu (hit F8 to pause bootup). Another option is to install and configure Setup 1.30 to detect your eGPU and configure your PCI configuration space prior to chainloading to Win7. AppInit_DLLs needs to be set for internal LCD mode to work For games to launch on the internal LCD on systems with an intel iGPU, the AppInit_DLLs needs to route via a DLL. NVidia sets this to nvinit.dll. During my tinkerings I have seen this registry setting missing so internal LCD mode didn't work. [H] "AppInit_DLLs"="C:WindowsSysWOW64 vinit.dll" ^top Non-Optimus Setup: x2/x4 >>> Set x2 link but mPCIe Port2 or Port4 enabled after reboot? On x2 setup (mPCIe Port1&Port2 or Port3&Port4), mPCIe Port2/Port4 must be disabled. If they left enabled, it can cause eGPU instability (e.g. 3dMark06 crashed while running benchmark). There are two methods for dealing this issue. First Method: modded PM3N (Source: Tech Inferno Fan) Second Method: two-pass script in STARTUP.BAT (Source: Tech Inferno Fan) ^top
