The results are now within what I'd expect of your Mac Mini. The somewhat misleading information is that 3dmark reports your system as having a i7-4710HQ quad-core CPU when in fact it's a dual-core i7. The Physics results (CPU) are therefore correct for a dual-core CPU.

Try setting Gen1 in the bios or using Setup 1.30 to see if it fixes the lagging. We've also had one user note that the NVidia power states were not switching correctly causing flakey behaviour. Something that was fixed by install NVidia Powermizer. If the lag is still present and obvious when gaming then it may point to crosstalk along the eGPU link that happens when the cabling has frayed.

You'd be referring to BITS, BIOS Implementation Test Suite: http://biosbits.org/

Thank you for posting your implementation guide. The 3dmark06 score confirms that PCIe compression is on. Your 3dmark11 showing similar cpu and gpu results to Balchov's ones below as extracted from https://www.techinferno.com/index.php?/forums/topic/8919-implementations-hub-tb-ec-mpcie/#dx11 14" Dell_E6420 i7-2670QM 2.2 8.0 EXP GDC V6 GTX680 4Gbps+c-EC2 7936 6591 Balchov Win8.1 The only further performance tweaks that could be applied then would be: - check CPU and temps to see if it's temp throttling using say Throttlestop TS-bench. If it's temperature throttling then consider repasting the CPU and/or other cooling solutions such as running without the bottom cover on or using a notebook cooler. - overclock the GTX680 with MSI Afterburner - extract more CPU performance by using a BCLK overclock. Potential gain is in the 4-5% range.

@lukeperman, would you mind running 3dmark13 and 3dmark11 and linking the results? Pls ensure your Windows Power Plan, setting it to 'High Performance' and re-run the benchmarks on an external LCD attached to the eGPU. I'm curious how the Inno3D card does there. It also means I can place you in the appropriate place on the leaderboard at https://www.techinferno.com/index.php?/forums/topic/8919-implementations-hub-tb-ec-mpcie/#dx11 Can I ask that pics and spec details be posted of the mac Mini?

Nope.. either have the cabled solution of PE4C V2.1 or EXP GDC that gives problems with Gen2 signalling, or get a soldered cable PE4C V3.0 or PE4L 2.1b. The latter rated at up to Gen3 speeed.

Setup 1.30 can help with detection of the eGPU as well as correct error 12 if you have it. It's suggested you work through https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/

Yes, Setup 1.30 can be used to switch the mPCe port from Gen1->Gen2 to gain more performance. Disabling the dGPU there can also improve DX9 performance. Contact details to obtain the software is at https://www.techinferno.com/index.php?/forums/topic/1650-diy-egpu-setup-130-previously-setup-1x/

BPlus have a PE4C V2.1 and there's also an EXP GDC Beast. Either can be used on a mPCIe or EC slot by changing the HDMI end cable. Problem with those is they introduce reflective noise due to the socket interconnects and so cannot be run at full Gen2 speed on 2nd-gen i-core or newer notebooks. BPlus solved the problem by soldering a cable onto the adapter in their PE4C V3.0. EXP GDC hasn't as yet fixed it. So unfortunately, this modular "solution" has already been provided in a slightly different form and has not been satisfactory. Most users with Gen2 capability simply want a Gen2 capable adapter, which this is not. If using a 1st gen-icore or older notebook then yes, you can use this. But why bother when EXP GDC or PE4C V2.1 is a better eGPU adapter?

Pls email me your devcon.txt file. I suspect you have a non-English entries which then act as exclusion zones preventing any allocation from happening.

Pls try hardwiring the PSU to be permanently on rather than switch on only when the eGPU is detected as described at https://www.techinferno.com/index.php?/forums/topic/8947-mpcieec-egpu-troubleshooting-steps/

PE4C V3.0 is the best eGPU adapter for your system. R9 390 will require a DSDT override on your Elitebook to work due to the limited BIOS-set TOLUD:

nvflash provided with Setup 1.30 doesn't detect the new GTX9xx cards. There is no newer DOS-only nvflash from NVidia to allow it either. GTX970 requires more PCIe config space than your GTX670. 32-bit PCI compaction will not be enough. If using a DSDT override then you should be setting a endpoint=56.25GB and performing a eGPU or iGPU+eGPU compaction.

Your questions are answered in this thread. Ie: you can attach the TB monitor to the TB port of the MBA or a TB port on the Thunderbolt enclosure. However, it is not ideal as the data is then being shuttled back via the iGPU across the TB link. The eGPU cannot directly drive the TB display. It's therefore best to acquire a different display that attached to the DP/HDMI ports on the eGPU if wanting to maximize eGPU performance.

Did you re-do the steps I posted previously? If done and problem persists then consider doing a Bootcamp 4.0 installation of Windows. Difference there it installs in MBR/BIOS rather than UEFI mode. That affects the initialization of the eGPU and may aid your Windows hang on boot.

If you go to View->Devices By Connection then the Bridges will appear above ordered above the dGPU and eGPU. There is no way of choosing the incorrect ones when viewed that way.

1. Remove ALL existing NVidia drivers, then use 'DDU' software to remove NVidia registry entries as well as disable automatic driver installation. Reboot system and load latest NVidia desktop driver: https://www.techinferno.com/index.php?/forums/topic/9289-optimus-now-works-in-win10-using-36175-driver/ 2. Free up dGPU resources: Go to Device Manager -> View Devices By connection. Find your D500 dGPU. Directly above it will be a PCIe Bridge. Disable it. When you do, the D500 will completely disappear. 3. Re-allocate your TB chain in an attempt to fix error 12. Go to Device Manager -> View Resources By connection. Find your eGPU. Now directly above it will be a multitude of PCIe bridges (5 or so). Disable them one at a time working your way up. Once done. Re-enable them again. 4. If you still see error 12, then the final fix that has worked for ZBook and Lenovo W54x Thunderbolt users is to perform a DSDT override: https://www.techinferno.com/index.php?/forums/topic/5874-guide-dsdt-override-to-fix-error-12/ I'll add too that the Thunderbolt SSD adds complexity to the eGPU allocation since it too needs to be allocated. I'd suggest do initial testing using a USB 3.0 drive instead. Then later on can add it and see if can get the drive + eGPU working concurrently. They should be on separate Thunderbolt buses to ensure don't share bandwidth: http://www.fcpworks.com/thunderbolt-bus-mapping-new-mac-pro/

Would you mind running 3dmark13 and 3dmark11 on your external 1080P LCD and posting the link to the results? Yours with a Skylake i7-6700K desktop CPU + GTX980Ti would be near the top of our leaderboard: https://www.techinferno.com/index.php?/forums/topic/8919-implementations-hub-tb-ec-mpcie/#dx11

Try a 15" HP ZBook G3 Studio. i7-quad power with an innovative cooling mesh as it's base. Has 2xTB3 ports too http://www.bhphotovideo.com/c/product/1209893-REG/hp_t6e17ut_aba_15_6_zbook_studio_g3.html

Yes, Setup 1.30 can be installed on your system and used for the purposes outlined in the opening post of this thread.

Your notebook has a x3100 igpu. NVIDIA does not provide accelerated internal LCD mode for an igpu that old. Need a 4500mhd or newer. Setup 1.30 can be acquired the if you see error 12 against the egpu when you connect it

Your 3dmark06 result is showing 48fps (average). This does not mean your lcd is limited to that. The more informative request would be for a y410 owner to provide 3dmark06 results. Then can deduce if they too are below what's expected due to x1 pcie compression not engaging for some (as yet) unknown reason.

Optimus ( accelerated internal.lcd mode and x1 pcie conpression) reqd the Intel HD igpu to be active, any dgpu to be disabled in bios or using Setup 1.30 and a GTS450 or newer video card. Pls confirm these. If any dgpu us still present then won't get the accelerated internal LCD mode or x1 pcie compression. Your low 3dmark06 (dx9)result looks to be not using x1 pcie compression. Can test say 3dmark11 or 13 either of which isn't as sensitive to the x1 pcie compression as they use dx11. Then see if how your result compares against similar specced machines at

Looks like x1 pcie compression has been disabled by NVIDIA. Thats because your cpu score is as expected but sm 2.0 and 3.0 are at least half of what we've seen with x1 compression active. Can confirm this theory by testing 3dmark06 on win8.1 with known good 350.12 driver that does x1 pcie compression.

Check your internal LCD frequency. It's the one that limits egpu fps when using Optimus egpu-accelerated internal LCD mode.
