    So, you're saying your PSU have 5 rails? That is not true. Your PSU have three 12V rails, not five. Different strands doesn't mean it is from different rails.
    No I understand that now, I was just giving my full power configuration to ask if there existed a setup that would work from my graphics card. So as long as I use each 6-pin on one of +12V1, +12V2, and +12V3, I should be able to power my card, or so I've inferred. That is all. Still have code 12 though, trying to get rid of it

    You already fixed Error Code 12 by booting with eGPU connected.

    I also get Error Code 12 if didn't boot with eGPU connected. In my case & also several other notebook, e.g. Lenovo x220, BIOS automatically reduced TOLUD (and reallocate other device memory resources) to allocate 256MB PCI space for eGPU. This is not true for all notebooks though. You mention earlier that TOLUD (TOLM for i7 quad core) doesn't change (0xC8000000) whether boot with or without eGPU. I think, your BIOS reallocate other device memory resources to create 256MB PCI space for eGPU. You can confirm this by comparing device resources between boot with & without eGPU connected. You can use AIDA64 to generate the report.

    Thank you for the response. When I get home I'll get AIDA64 and confirm it. Even if I do confirm it though, how can I go about solving my crashing problem? I think I may try a friends power supply with my system and see if anything changes. If my eGPU is getting it's 256mb, than (other than power), what could my problem be? Could it be the fuse bypass jumper, which I still haven't done yet?

    I am going to solder my fuse bypass jumpers today and I have the 2.4 PE4H kit, which has 3 fuses rather than the 2 that are in the 2.0 kit which the tutorial is over. Do I solder bypasses over all 3 fuses? Or just the two above the FDD? Thanks for all the help, I'd be nowhere without you (and some others as well).

    That is for your information only. So that you know why you didn't get Error Code 12 when booting with eGPU connected.

    I already said PSU is insufficient which explain why it crashing whenever you tried to run games or benchmarks. Unless you mod your PSU to bridge, let say +12V1 & +12V2, graphic card only draw power from +12V1 which is insufficient for any 3D job. If I'm not mistaken, I already advice you to set the fuse bypass jumper on PE4H. So, I taught you already did that. If you look at Common FAQ5 in eGPU Troubleshooting page, you'll see this:-
    The solution is to set the PE4H 2.4 fuse bypass jumper (near the floppy molex connector).

    I know that question has been asked before without any answers given... But WHY hasn't anyone made an mxm card to full length pcie x16 adapter?

    my mxm type II slot is the fastest on my motherboard, and it makes perfect sense that a person might want to hook up an egpu to that slot!

    I wish I was more knowledgeable about this stuff, because I would design one and have it made myself.

    So on the 2.4 system, I just have to jump the one fuse that is directly behind the floppy, not the two that are to the left of it, because there two to the left look very similar to the ones modded in Panzer's guide.

    Now successful install the driver, no error code, but screen is lagging and when i try run the 3Dmark, laptop screen went black. Please advise.

    MXM specification is controlled by Nvidia & it is not publicly available. Any company that want to get the specification must be a member of MXM-SIG group.

    I can only speculate why no one made a MXM kit yet:-
    1. Don't want to pay fee to become a member of MXM-SIG group. I'm going to assume it's not cheap.
    2. Without MXM specification, the only way is to use reverse engineering method. This is likely violate MXM license since not a member of MXM-SIG group. Can get sued.
    3. MXM is for mobile graphic card. Using it with desktop graphic card is likely violate MXM license. Can get sued.


    Not to forget, we also need SBIOS1 support to get eGPU to work with MXM interface.

    You don't see a jumper near the floppy power port? You don't need to do Panzer's fuse bypass mod if you have PE4H v2.4 because a jumper already available.

    What is the PSU specification, especially +12V max current? GTS450 power requirement is 106W. So, +12V max current should be around 9A to 10A at least.
