You raise a good point. I'm getting a fair few intermittent "NVidia driver has stopped working" issues with a EXP GDC V6 that I didn't have with a PE4L 2.1b. NVidia drivers having little fault tolerance if the link can't maintain Gen2 speed, requiring either downgrading the port to Gen1 link speed and losing half the bandwidth along with it or getting a better eGPU adapter.

ATM testing a PE4C 2.1 to see if it's any better than EXP GDC V6. Wonder if EXP GDC V7-Areas or newer EXP GDC Beast have better signal integrity?

So I've figure out that the reason for my "NVidia driver has stopped working" issues is my fridge: every time my fridge compressor turns on, my screen goes black and the "NVidia driver has stopped working" occurs.

I'm not really sure how to fix this, besides using a different outlet for my fridge (so. many. extension cables). Would using a PSU instead of the DA-2 solve the problem?

I've also heard that using a higher quality HDMI cable might solve the problem. Anyone know where I can buy a better HDMI to mPCIe cable?

@jjbron (jjfish?)

What PSU are you using atm (12V amp rating)? Forgive me if I asked this already.

I'm using a Dell DA-2 atm, (model D220 P-01). It says it can output 12A-18A.

Wait, can the y470 + 560ti + EXP GDC v6 run at Gen2?

@jjbron

I guess Win+P -> Projector only doesn't do much for you? Try update 'check for hardware changes' in device manager too, sometimes I need to disconnect and connect twice to get external screen output.

I'm an idiot. Turns out the DVI cable was broken.

THANK YOU ALL. IT LIVES! NVIDIA GeForce GTX 560 Ti video card benchmark result - Intel Core i7-2630QM Processor,LENOVO Base Board Product Name

EDIT: actually the screen goes black every once in a while when gaming, and "The display driver has stopped responding" appears. Any ideas?

Hello,

I've got my eGPU installed & drivers installed (device manager says the device is working properly), but I can't output anything to my external monitor. (Turns out I didn't need to whitelist anything).

In Setup 1.30, I run set eGPU port width to Gen2, PCI compaction on iGPU + eGPU, then Hot Reset my eGPU port, then Chainload Mbr.

In Windows 7, in the screen resolution window, what I see is "Available display output on: NVIDIA GeForce GTX 560 Ti", and my only options are "No display detected" and "Try to connect anyway on VGA".

Any ideas @Tech Inferno Fan?

Is that your black screen? Worst case scenario would be the EXP GDC shorting your systemboard and it's black screening then turning off on startup to protect itself against permanent damage.

Sadly I've tried disabling the internal GPU, and nothing changes. Whenever I plug in my EXP GDC, the screen goes out: if it's in Setup 1.X, the screen goes blue; if it's mid-boot the screen stays black; if it's in Windows; the screen goes white/blue.

I think it's a whitelist issue, I've noticed that Setup 1.X isn't detecting my mPCIe port. However, when I try to restore the port, Setup 1.X gets stuck in "gathering resources to build screen". Any ideas?

Hi,

I'm trying to get my y470 + EXP GDC v6 + 560ti setup running, but anytime I plug my eGPU into my laptop (w/ mPCIe cable), my laptop instantly freezes (screen blanks out) then turns off. I've tried booting with the cable in (black screen), and plugging the cable in while my laptop is asleep (black screen when resuming).

I think the issue is my y470 has a whitelist on the mPCIe port? I can chainload mbr without any problems, and I used DDU to get rid of my dGPU drivers.

However, every time I try to restore a port, Setup 1.30 hangs on "Getting details". Every time I try to restore all ports I get "Abort, Retry, Ignore, Fail".

Any ideas?

Hi buddy.

Are you saying you don't have the ATX adapter cable?

Some users have been feeding the EXP GDC via the 6pin power output, so yes 3 x 6pin would be required in your case but I suggest getting the cable above instead.

The user I quoted used both the ATX adapter cable & 3 x 6pin. If I use the ATX adapter, do I need to put cables into my gpu's 2 x 6 pin ports?

- Buy the ATX adapter from Cloudhero

- Plug the 8-pin end of the ATX adapter into the EXP GDC 8-pin port

- Plug the 20-pin ATX power cable from your PSU to the 20-pin port in the ATX adapter

- Whatever you do, do NOT plug anything into that square 4-pin on the ATX adapter, it'll either melt like Coyote's, or the EXP GDC will switch on and off immediately after boot / not switch on at all - depending which way you plugged the 4-pin in. Leave it unplugged. (And someone should really tell Cloudhero)

- Connect a 6-pin PCIe power cable from your PSU into the 6-pin EXP GDC port, the one on the end. Yes normally you would use that port to plug in the 2-way 6-pin cable into your graphics card - Don't.

- Now use another 2x PCIe power cables 6/8-pin (depending on your gfx card) from your PSU to plug into your graphics card. You may not have enough PCIe plugs here so you might have to be creative and use flat 4-pin power to PCIe adapters.

Hoping someone could clarify using an ATX PSU. My gpu (560 ti) needs two 6pins, so do I need three 6pins total on my ATX PSU (one for the EXP GDC, 2 for the gpu)?

Or, couldn't I just use the 6-pin to dual 6-pin, modular cable but power the EXP GDC with an ATX PSU? (so basically the normal DA-2 setup, but with an ATX PSU instead?)

On yoybuy it links to either the "no power" (ATX) or 220W power kit as sold on taobao (China). The no power kit comes with the ATX lead. The 220W kit comes with the 6P+6/8P pcie lead used to draw power from the 220W DellDA-2 AC adapter via the EXP GDC board.

By contrast, the "no power" kit on banggood also includes the 6P+6/8P pcie lead. Useful in case you want to source the DellDA-2 AC adapter locally, which it seems the seller Cloud is promoting.. Good deal there at US$50/US$53 for the mPCIe/expresscard version: http://www.banggood.com/EXP-GDC-Lapt...-p-934367.html

So I don't need the 6P+6/8P pcie lead if I'm using a ATX PSU? and where's the "no power" EXP GDC on yoybuy (I can't find it searching yoybuy)?

Yes it is possible, just start a chat with your dealer and specify that you need this item, the actual item, it comes at an extra value of 5-10 bucks and tell them to ship it together, that's what I did;

ATX TO EXP EXP GDC power supply turn GDC desktop power supply wiring Item

So I don't need the "6-pin PCI-e power cable"?

Just to clarify something, if I want to use an ATX PSU with the EXP GDC v6/v7, do I need to buy the 'ATX power cable' and the '6-pin PCI-e power cable'?

If so, is it possible to buy both cables off yoybuy?

Thanks
