The opening post refers to using Setup 1.30 software to hard allocate the egpu into the created "Large Memory" area if the OS doesn't do it for you.

Lenovo wired the T430/T530 expresscard to the southbridge, which has pcie 2.0 ports. Afaik, no manufacturer ever wired their expresscard to the north bridge pcie 3.0 port (3rd gen icore or newer). If you need more bandwidth then consider a Thunderbolt egpu solution.

Boot Setup 1.30, then use the PCIe Ports->Gen2 menu. Setup 1.30 is available at https://www.techinferno.com/index.php?/files/file/87-diy-e-gpu-setup-130-by-Tech Inferno Fan/

Pls use easybcd to add a second boot item to your primary her that points to the windows on your Usb drive. Then install setup 1.30 on the primary her and use its chainloading mbr to bring up that primary her bootmenu from which you select the usb HDD win installation. Need to do this because the grub bootloader probably does not recognize your Usb drive and so can't boot the setup 1.30 image off it.

Pls check if your using got or mbr partitions to host your windows. Setup 1.20 requires mbr partitions. If it is mbr and disk image install is still problematic, then pls use a USB stick installation instead.

DSDT override process that you'll need to host your gtx750ti is at the following URL. If cant nut this out then consider getting a gtx660/670/760/770 all of which have a smaller pcie aperture that can fit within the 2570p's bios set TOLUD limit.

Yes, some notebooks like yours do not have the igpu wired through. Therefore optimus wont work. Your only option for internal lcd mode is to drag and drop a *windowed* app started on the external lcd to the internal lcd. It's possible to do that without using a physical lcd by way of a VGA or dvi dummy plug on the egpu to provide a fake external lcd. Then use software like Actual window manager to start the app on the fake external lcd and move it to the internal lcd. Good luck with it.

That's when the egpu tries to send output to the attached lcd which requires increased poer. If the power drawn by the egpu then is greater than the max of the psu, or the psu is faulty, then the psu will power off. Pls try another more powerful psu.

Both your dgpu and egpu are allocated ok. With the egpu powering off, check you power leads and psu attached to it.

Pls run C:\egpu\uninstall-disk-image as admin user.

Pls work through https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/

dgpu must be disabled for the egpu to be given NVIDIA Optimus functionality. So then pls remove all NVIDIA drivers, then use ddu to remove NVIDIA registry entries as well as disable automatic driver installation. Then install the latest NVIDIA desktop drivers. Change your Setup 1.30 startup.bat to be: call speedup lbacache call vidwait 60 call vidinit -d %eGPU% call iport dgpu off call pci :end call chainload bootmgr noremap

Pls re-download Setup 1.30, extract and re-install. If the error persists, the pls do a USB installation.

Danny, several users with this Macbook have reverted to a MBR/bios installation of Win7/8/10 and then use DIY eGPU Setup 1.20/1.30 software to eradicate error 12: http://tiny.cc/Setup1x

Pls run Save Diags->compact_fails within DIY eGPU Setup 1.30. Then boot windows, run c:\eGPU\eGPU-setup-mount (as admin) and winzip/winrar the v:\diag folder. Email that file to me for evaluation.

3dmark06 (DX9) shows across the board performance improvements for the E6430 over the X230. With 3dmark11/13 (DX11) we do see the E6430 is slower though unlike the 3dmark06 results, several months separates the benchmark runs. They are not run back-to-back. If back-to-back DX11 results continue to favor the X230 may I suggest doing an OS reload just in case something is amiss with the DX11 subsystem?

Pls run 3dmark06 on the E6430 and post the link to the results. Are you connecting the external LCD using the eGPU rather than notebook? That ensures direct video traffic out rather than using NVidia Optimus which slows things down.

Your SSD is getting just under 500MB/s read speed on your 8460P with F.60 BIOS. That is definitely at SATA-III link interface speed as explained at http://kb.sandisk.com/app/answers/detail/a_id/8142/~/difference-between-sata-i,-sata-ii-and-sata-iii below. So no need to change your BIOS. Difference between SATA I, SATA II and SATA III What is the difference between SATA I, SATA II and SATA III? SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s, is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s. SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s. SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface. SATA II specifications provide backward compatibility to function on SATA I ports. SATA III specifications provide backward compatibility to function on SATA I and SATA II ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port. Example: SanDisk Extreme SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to 550/520MB/s sequential read and sequential write speed rates respectively. However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 285/275MB/s sequential read and sequential write speed rates respectively.

I don't have 50 points to get 68SCF8.zip with nor own a 8460P to grab a dump from.

Only change of doing it is getting a F.20 8460P bios dump using fptw64 (Intel Flash Utility) and flashing it to your system. Required is unlocking the flash descriptor which accomplished by holding WIN+LEFT ARROW+RIGHT ARROW key pressing power on button. 8460P BIOS dump can be found at http://forum.hpfocus.com/viewtopic.php?style=51&f=2&t=2475 fptw is contained in https://github.com/LongSoft/FTK/releases/tag/0.12.0 HP have otherwise prevented downgrading BIOS as you've found using their tools.

A comprehensive writeup. Thank you for your contribution Only two other tidbits that could improve it further: 1. Some pictures of the rig all wired up and running to bring it all to life. 2. Benchmark runs of 3dmark13 (Firestrike) along with your 3dmark11 ones so can add you to the appropriate place on the leaderboard chart.

@mmomega, would you mind downloading PCI scope Trial from http://www.tssc.de/site/products/tools/pciscope/default.aspx, saving a dump (BPD) file of your working configuration and uploading here? @chrise and another offline user are getting error 12 with this system. The supplied info will mean a custom pci.bat via Setup 1.30 (MBR Win10 install) can be created to fix error 12 on this system.

It would be VERY big news if AMD introduces a Optimus like driver allowing an AMD to accelerate the internal LCD. Wouldn't be surprised if they license out the LucidLogix Virtu software to accomplish that. I noticed Lucid no longer offering their product for sale: https://www.techinferno.com/index.php?/forums/topic/2324-lucidlogix-virtu-internal-lcd-mode-for-amd-egpus/

There is a LED on the Dell DA-2 just below where the 8-pin cable attaches to it. It will be orange when you plug power into it indicating it's in standby mode. It will be green when you GND the remote pin, indicating it's providing power. If you get no activity from the LED then your Dell DA-2 isn't powered on or is faulty. For the former check your power socket and power cable.
