Would someone pls try the steps in my last post to see if modified NVidia laptop drivers enable Optimus under Win10?

I wouldn't. The Razor core will go on sale second half of this year with no known price as yet. You'll need a new TB3 capable Skylake system and new enclosure to take advantage of TB3. TB3 sees a doubling of TB2 bandwidth (32Gbps versus 16Gbps). Whatever GPU you buy can be transplanted later into a TB3 enclosure if you want to go down that path. AKiTiO Thunder2 is well priced and has good availability and great results.

Can you please shortlist the exact hardware configuration you are using, software configuration necessary and 3dmark11 and 13 benchmark result runs?

Wow! The Brix is mini PC barebones system. http://www.gigabyte.com.au/products/list.aspx?s=47&ck=104 We do not have any implementation guides for that system. Would you like to submit details of yours so others with a Brix can replicate your pioneering efforts?

Ask BPlus if they can help you out. x2.2 is such a rare possibility that eGPU adapter manufacturers haven't included the capability into their hardware. x1 2.0 is their chosen link width.

PE4L 2.1b only has a single EC or mPCIe connection. To get the 8Gbps with the E6430 requires an egpu adapter that allows combining the EC+mPCIe or mPCIe+mPCIe like the PE4C V2.1 (now discontinued). That hack might only be possible using an AMD cards since NVIdia cards are sensitive to Gen2 glitching that eGPU adapter would like experience due to the non-soldered interposer cable used.' @timohour explains how to get the x2.2 link in that thread.

Not sure why you believe you need a DSDT override. Use Setup 1.30 (which you have) to have the GTX960 hijaak the GT525M's PCIe config space to overcome error 12. If need help with this them email me.

W510 is only Gen1 (x1 1.1) eGPU capable. Definitely want a Gen2 capable 2nd-gen i-core or newer machine like the W510. Furthermore, the W510 has no active iGPU so could never provide NVidia Optimus. Though one big positive of the W510 is according to http://forum.thinkpads.com/viewtopic.php?t=94738 is has the highly regarded B156HW01 v4 LCD (FHD, dual-channel LVDS 40-pin, matte, 95% gamut). You may then consider swapping your W510 and T530 LCDs.

Yes, a DSDT override can be applied in memory via Setup 1.30, alleviating the need to make registry changes (inc turning on test signing mode in Win8/10). If going that route then the T530 dGPU model then has some more flexibility than the iGPU model. You can disable the dGPU and hijaak it's PCIe config space to host the eGPU making the DSDT override unnecessary. Changing HD to FHD panels may require an upgrade from a single to dual-LVDS cable that connects from the systemboard to the LCD panel. Investigate on the forums or with Lenovo. These are the highly praised 95% gamut LVDS panels found in W520/W530 systems: http://lepus-tech.com/Laptop-LCD-LED-Panel/Panel-15.6/B156HW01-V4 (matte) http://lepus-tech.com/Laptop-LCD-LED-Panel/Panel-15.6/B156HW01-V7 (glossy) Accelerated internal LCD mode requires part of your x1 2.0 expresscard bandwidth to shuttle display image data across. An external LCD attached to the eGPU uses that x1 2.0 bandwidth exclusively, so will give better gaming performance.

If are confident of doing a DSDT override then the T530 iGPU model would be the preferred option. Usually less costly than the dGPU model. arteart successfully applied a DSDT override on a iGPU-only T430 at https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12/ which then gives a plug'n'play solution.

I'm not at my system atm. Would somebody like to test if a modified NVidia Laptop driver enables the accelerated internal LCD with Win10? No mention of anybody testing this as a workaround as yet. Many notebooks sold with the Optimus feature so it would make sense for MS and NVidia to ensure this feature is maintained in Win10. Instructions to do this are below: Modifying and Installing the NVidia Laptop drivers Step 1: Modify the NVidia Laptop driver INF files as summarized from here Assuming that the graphics card was detected when the drivers were installed, you are ready to proceed to the next step. Download the newest NVIDIA LAPTOP drivers that have the same architecture as your external graphics card (If you have a GTX 970, download GTX 970M). Generally speaking the newer cards all have the same bundled driver, and you can find them all on NVIDIA's Driver Downloads site. Use a tool to extract the installer into a folder (I used WinRar). The result should look something like the picture below Now there is a specific file that we are looking for called "nvami.inf". Basically the idea is that we're manually adding our desktop graphics card to the list of laptop cards. This is easily done by the addition of 3 lines of code after finding the Hardware ID of your card from Device Manager. In the device manager, navigate to the external card then go to Properties->Details (Tab) and under the "Property" drop down select "Hardware Ids". An example using the Quadro K620 is shown below. The 4 character alpha numeric string after "PCI\VEN_10DE&DEV_" is the important number; in this case it is "13BB". Time to add the code. You can use a text editor (such as notepad) to open the nvami.inf file inside the driver folder (just search for it). The result will be like below. Navigate to the text "[NVIDIA_SetA_Devices.NTamd64.6.0]" and COPY "NVIDIA_DEV.XXXX= Section099, PCI\VEN_10DE&DEV_XXXX" replacing "XXXX" with your hardware ID below the text. Copy the exact same text under "[NVIDIA_SetA_Devices.NTamd64.6.1]" (it is just further down the list). Now navigate to the "[Strings]" section and COPY "NVIDIA_DEV.XXXX = "(Your card name)"" below the section. You must enclose the name in double quotations. Now save the text file. Step 2: Install the modified driver Uninstall any desktop drivers you may have installed. Then disable driver signature enforcement [Win8 or newer] to allow modified driver installation. Do this by: Hit the "Shift" key while clicking onto the "Restart" option. After the reboot choose the options "Troubleshoot" > "Advanced Options" > "Startup Settings" > "Restart". During the next reboot hit "F7" (= option "Disable driver signature enforcement"). Once the OS is up, proceed to navigate to your modded driver directory and run the Setup executable. Until the next reboot you can install as many unsigned or modded drivers as you want or need to.

Ivy Bridge supports maximum PCIe 2.0 (Gen2) speed on the expresscard/mPCIe slot. BPlus PE4C V3.0 with it's soldered cable the eGPU adapter with best chance to provide glitch free Gen2 eGPU operation. There are issues with Win10 Optimus mode: https://www.techinferno.com/index.php?/forums/topic/8918-egpu-window-10-optimus-mode-problem/ . Those problems have been confined to using the desktop driver. No reports yet in that thread of anybody modifying the mobile driver INF with desktop card PCI-IDs to see if it fixes the problem. A possibility. Otherwise Win7/Win8.x Optimus works well. TOLUD issues can be solved with either: 1. modded/update/rollbacked BIOS that lowers TOLUD 2. getting the dGPU model, disable the dGPU and hijaak it's PCIe space using Setup 1.30 3. applying a DSDT override

To be able to use the internal LCD to be accelerated by the eGPU, a feature known as NVidia Optimus, you require: 1. An Intel HD or better internal graphics (HD iGPU) 2. A NVidia GTS450 or newer video card 3. Windows 7 or 8.x only. Windows 10 has broken NVidia Optimus so will not work https://www.techinferno.com/index.php?/forums/topic/8918-egpu-window-10-optimus-mode-problem/ Now some systems' BIOS will switch off the HD iGPU upon detecting the eGPU on bootup. Maybe X201 is one? If so, need to ensure the BIOS does not see the eGPU on bootup by either using the delay switches (CTD/PTD) on it OR hotplug the expresscard after BIOS bootup but before the operating system loading. You can check if NVidia Optimus is engaged by opening the NVidia control panel on the HD iGPU attached LCD, clicking Adjust Image. Then a NVidia logo will spin around. Alternatively, run a benchmark like Resident Evil 5 or 3dmark06 on the internal LCD with and without the eGPU attached. The results with the eGPU will be noticably faster.

Can anybody confirm if F.50 bios or thereafter prevents ME FW updates. 1. Power off the NB 2. press the WIN | left arrow | right arrow button (all three together and hold them) 3. power on the NB 4. on the first message on the display release the buttons. You see then an new message on the first line: HDA_SDO. To lock SPI, do global reset or remove AC & DC then boot after updating SPI. If can no longer do this then the only way to unlock the ME FW for read/write with these newer BIOS is to jumper the audio chip. HP's F.50 BIOS notes indicate:

@stemoac, very good news to hear you have it all running especially with the high performance GTX980Ti. We have only one other documented 2011 iMac eGPU implementation guide at https://www.techinferno.com/index.php?/forums/topic/7993-2011-11-mba-13-mbp-imac-gtx97010gbps-tb1-akitio-thunder2-osx1010-seefew/#post136810 Would you like to post an implementation guide with this newer iMac so other users with the same system can leverage off your pioneering efforts?

Worth checking if your desktop motherboard vendor released a SLIC 2.1 BIOS. In which case you can load Win7, load the OEM certificate and license and have an activated Win7. Something that Dell/HP did with their notebooks as they transitioned from Vista to Win7. Maybe desktop manufacturers did too?

For accelerated internal LCD mode (Optimus) you'll need whichever NVidia card you can get for $170. Eg: GTX670/760. Just ensure the maximum TDP is below your PSU's output. For instance, if you have a Dell DA-2 PSU, it's rated at 220W. That will limit you to say a GX680/GTX760/GTX960. Also note that Optimus is broken with Win10. Requires 7 or Win8.1 to work properly: https://www.techinferno.com/index.php?/forums/topic/8918-egpu-window-10-optimus-mode-problem/

If those benchmarks are indeed using the eGPU then clearly x1.2Opt is having problems on the PE4C V3.0. Unusual that Gen1 works though. It's something you may want to discuss with BPlus to organize a replacement adapter. Crosstalk between the expresscard wires could lead to data resends along with such a marked loss of performance.

1. You can undervolt the CPU with XTU and optional increase fan speed to lower temps to extract some more CPU performance. 2. Adding a GTX980/980Ti Thunderbolt eGPU will improve your graphics processing/gaming. Lots of info about that at https://www.techinferno.com/index.php?/forums/forum/83-diy-e-gpu-projects/ Eg of both of the above implemented, though in a custom chassis (a bit more complex) at https://www.techinferno.com/index.php?/forums/topic/9062-2013-15-mbp-gt750m-gtx980ti16gbps-tb2-akitio-thunder2-caldigit-win81osx10105-jmlee5/ Can see easier implementations at https://www.techinferno.com/index.php?/forums/topic/8919-implementations-hub-tb-ec-mpcie/#Thunderbolt

Though keep in mind the EXP GDC Beast tries to do power management. Ie: power up the ATX or Dell DA-2 *after* detecting the expresscard slot signal.
