@airbusa321 Try plugging the eGPU in/starting it when you're in the boot menu. What do you mean exactly with "splash screen"? Have you had a look at one of the implementation threads for a 13" 2015 MBPr?

You can't use HDMI - Thunderbolt cables(if there are any existant) and there are no adapters either. Thunderbolt needs verification on both sides of the connection and you can't get that with such cables. Forget about the EXP GDC and a Macbook with Thunderbolt. To use the linked Adapter you'd need to remove the bottom plate, which isn't smart to begin with, and you'd need to let it removed for the time you use the eGPU. Honestly you don't want this. Get the Akitio Thunder2, pay once the higher price and have fun for a longer time.

There are only 2 models made by Asus that don't require the 6 pin connector. Keep in mind that the chip isn't designed to be powered solely by the PCIe slot and maybe they'd throttle when they exceed the 75W. Just a thought though, of course I don't know for sure. Otherwise it's simply faster than the GTX 750 Ti, the GTX 950 exceeds the GTX 750 Ti by about 3000 points in 3DMark11. Given the improvement from 750 Ti to 950 we may see around 12000 points in 3DMark11 which would be amazing given that it only needs up to 75W. So I'd definitely wait or get a cheap card(used 750 for example) for the time until release which can then be sold again. The EVGA thing was only about the use of the internal display which was easier with EVGA models due to internal bootup timings of the cards, when I'm remembering that correctly. There are easy fixes though to make that happen with every card so that shouldn't be a matter at all.

1. Stable. Why should it be unstable? The Akitio doesn't like AMD cards though, they tend to crash randomly, so you should stick with Nvidia cards. If you want to use the eGPU on your internal display you're bound to Nvidia anyway. 2. Usually you boot up, hold the ALT key for the boot menu to come up and then you turn on the eGPU which is plugged in already. Then you boot Windows. Same procedure as of first boot, because you can't install the drivers unless the card is connected. 3. Dell DA-2 or a usual ATX PSU both with a 2.5mm x 5.5mm barrel plug which you have to built yourself. See https://www.techinferno.com/index.php?/forums/topic/7377-220w-dell-da-2-ac-adapter-discussion/, especially post #2. You'd have to modify the enclosure though if you want to close the Akitio case or the wires because the PCIe power plugs usually block at the top and the card get hot when closed and throttles. Otherwise, if leaving it open is fine, you'd just have to find a card with max. length of around 20cm.

1. No. You need a PSU that delivers more wattage as you need up to 75W(or even more if the card doesn't acknowledge the PCIe specification) + some wattage for the Akitio board itself. The Akitio comes with a 60W PSU, not a 72W. You may take one of these -> https://www.amazon.com/eFreesia-Adapter-Monitor-Compatible-Devices/dp/B00JFCVOYU/ref=sr_1_5?ie=UTF8&qid=1473593725&sr=8-5&keywords=120w+2.5mm The important part is that you need 12V and a 2.5mm x 5.5mm plug. Everything 120W and higher should be fine for a setup like yours. 2. Pretty much, yes. 3. Yes, should work out of the box as far as I've read here(I'm on Windows 8.1 only). If it doesn't there are easy fixes. You don't need to disable the internal display itself, you simply disconnect it in Windows(I do it that way) if you don't want to use it and turn off the backlight before doing so. Just as a hint: You may consider waiting for the GTX 1050 which is supposed to be without the need of a PCIe power plug again, in comparison to the GTX 950.

I just want to confirm before purchasing questions
Morv replied to fernangus's topic in DIY e-GPU Projects
The only way for you would be to use the mPCIe slot where your wifi card is put into. The bottom plate is fixed with 8 screws but the bottom plate doesn't seem to be thought to be removed by the user. You'd void your warranty and maybe wouldn't get the bottom plate fixed again. Also there may be trouble with the display as the device is a convertible. So , summarized you should actually simply forget about using an eGPU with your notebook. If you'd like to use an eGPU sell your notebook and look for one that is suitable for one. -
For this to work it would be necessary that any of the PCIe slots is actually connected with the Thunderbolt controller and I highly doubt that this is the case on any mainboard. These Thunderbolt ports are thought to connect something to the mainboard and not the other way around. Also it's mainboard and expects a CPU and a running OS. The Thunderbolt ports need drivers to work and those won't be present in the BIOS/EFI. So no, this is not going to work at all. Just go for the Akitio, build a pseudo mainboard from some material(acrylic glass for example) and put the adapter on there. That way you can also use desktop cases.

Ok, then you're right, we didn't understand each other. I thought it was about PSUs that don't need soldering. Because you can use the usual DA-2 without any bit of soldering but the way you described is probably less fiddling for someone who knows what he's doing. In another post I saw someone soldering a cable from an 8 pin socket right to the GPU PCie sockets(see here). So you mean you could solder the cables coming from that 8 pin socket to the board internally and from there to the PCIe sockets or use plugs and by that you could use the full 220W. I got that right now?

Asus: TB3 may have too much latency and overhead for eGPUs?
Morv replied to bourbon's topic in DIY e-GPU Projects
Probably just the justification for using something non-standard so people have to use their machines. Most machines with TB3 known to me don't have two TB3 ports but only one. -
And like I said, a modded DA-2 is then completely unnecessary. Get a usual 120W power brick with 5.5mm x 2.5mm connector and you're fine, no soldering needed too for exemplary 18€. You'd only pay additional bucks for something you don't need and can't use anyway if you buy that modded DA-2. The usual DA-2 costs about 20€ and you don't need to solder anything if you want to use it with PCIe power plugs, it's been shown several times.
-
You don't get PCIe power plugs(6 or 8 pin) out of this modded DA-2 without using any adapters and extra wires so there's not really a point in using this at this price. The usual DA-2 + some PCIe power plug splitters and the barrel mod isn't any more complicated. Also using only the barrel plug with the Akitio only provides you with 75W anyway so there's no win and the DA-2 is way overpowered. There are 120W PSU with the correct barrel plug that are sufficient for slot powered graphics cards.
-
Don't install the mobile drivers but the usual desktop drivers for the GTX 970. Every desktop card works as an eGPU but you need the correct desktop driver. The mobile driver for the GTX 980 works for the desktop GTX 980 solely because it's actually the exact same chip in both versions only with lower clocks for the mobile version.
-
PCIe devices connected via Thunderbolt are only running with their max. PCIe specifications compatible bandwidth. That's why with TB2 you "only" use 16 Gbps(PCIe x4 2.0) of the 20 Gbps the TB2 connection can provide. With TB3 it's 32 Gbps of 40 Gbps because of the same reason(PCIe x4 3.0). Your values are fine.
-
This ammo box case is damn cool, I think I'm gonna rebuild that They're also pretty cheap on eBay but they are like the best thing for an eGPU regarding form factor. Awesome work!
-
There won't be 220W flowing through the barrel plug when the slot only draws 75W(+whatever the TB board needs) or am I wrong here? I don't see a problem. @benjaminlsr Why do you want to use the Dell DA-2 if you only want to power the Akitio through barrel plug? You usually use the DA-2 if you want a compact PSU that can deliver power to some additional PCIe power plugs. If you're just using a graphics card that doesn't need additional PCIe power plugs, then search for a 120W PSU that already has a barrel plug given.

[GUIDE] Making a molex-to-barrel adapter
Morv replied to jacobsson's topic in Enclosures and Adapters
Yup. But honestly I wouldn't twist the brown cables together and glue them, just isolate them seperately. I've simply used some duct tape once. @Dschijn It works for me. -
[GUIDE] Making a molex-to-barrel adapter
Morv replied to jacobsson's topic in Enclosures and Adapters
Yup. 2 black, 2 yellow, that's fine. Twist black and yellow cables and you're good to go. -
The riser is the problem, if you read that it is and already got told it in the automate-eGPU thread, why are you not simply solving the problem? And hell, don't buy a freaking overprized Bizon box. All you need is one of these things: https://www.amazon.de/adaptare-93525-DC-Hohlstecker-zweipoliger-Terminal-Block/dp/B01H5C29C2/ref=sr_1_2?ie=UTF8&qid=1467030067&sr=8-2&keywords=terminalblock+2.5mm Then cut off the Molex cable of the riser near the glue, strip a bit of the hull at the end of the cables, twist the cables if there are more than one per black and yellow. Then put the yellow one into "+" and the black one into "-" and fix them by screwing. That's all. Had a riser in use at the beginning and yes it was the problem. I'm using this molex cable for a few weeks again now since my Dell DA-2 died. Still works fine. Ask again if something isn't clear enough.

No, you can't do that. A Thunderbolt connection transfers a PCIe connection and those are bound to one host. You'd need to buy everything twice if you want to use it simultaneously, obviously.

Reenabling csrutil issue causes screen issue
Morv replied to rabass's topic in Apple eGPU discussion
SIP needs to stay disabled. https://www.techinferno.com/index.php?/forums/topic/7989-script-automating-the-installation-of-egpu-on-os-x-inc-display-output/&do=findComment&comment=133301 -
No. Thunderbolt needs hand-shaking parts on each side of the connection, unless you have those you're not going to build up a connection. Also HDMI wouldn't be able to provide the bandwidth TB3 delivers, not even fully TB2. The only hope would be Bplus producing a cheap adapter but there's nothing known about such things.

Intel unveils Thunderbolt 3.0, mentions eGPUs (Skylake 6th-gen i-core)
Morv replied to abe's topic in DIY e-GPU Projects
Yes, that's pretty much legit. Skull Canyon has got a quadcore i7 6770HQ and up to 32GB of RAM, so yes it's pretty much capable of running anything available together with the eGPU.- 199 replies
