This seems very very interesting. Wish something could be done close to this idea in the future.

Wanted to report some issue with the EXP GDC. I was playing heavy demanding games such as Crysis or Watch Dogs, I get a BSOD with "Video DXGKRNL Fatal Error" which seems to be related to watchdogs.sys and nvlddmkm.sys. Looked around on Google for about a week trying to figure out what was the issue, ran through myriad of troubleshooters, reinstalled Win8, upgraded to 8.1. Nope. Playing BF4 I had no BSOD but at times FPS would drop, a look to GPUZ and Gen2 "switches" to Gen1. Took EXP GDC and plugged back the PE4L and Crysis 3 ran flawless. I have no clue why this is happening. I mean why EXP can't maintain the Gen2 speed. EDIT: crazy grammar errors. Aw my Gawd!

Lol I was sitting trying the whole setup, just looking at it and saw some smoke beginning to come from the 4 pin, I disconnected the EC, waited a couple of secs and unplugged that 4 pin. Luckily the EXP GDC survived...It's somehow risky and they should provide some advices for first time users to avoid them such mistakes. Anyways the eGPU setup is running fine, tried WatchDogs (which is a mess), BF4, Crysis 3, all are good. The unplug-turn off feature is great as much as the restart laptop without having to go through the unplug-replug process.

Yeah there's some issue I wouldn't had expected, the 24 ATX pin specially. The 4 pin are inverted, they burned but somehow the EXP GDC survived. As I mentionned, I had to buy some other connectors, put 6 pin to the EXP and 8 pin of the 24 pin adapter, the 4 pin though, since it burned, weren't connected. Everything is working nice now no worries

I have a Corsair VS 350, all the white plugs are either from the GPU or the EXP GDC, never from the PSU. I only have a 8 pin from the PSU. No native 6 pin. BTW I already have a PE4L 2.1b that works flawless. When I plug the EXP GDC EC, only the PSU fan spins, the GPU is dead silent. Edit: SOLVED!! Ok so there was a 6+2 pin from the PSU. What you asked me tickled my ear. I forgot about this cable. took the 6 pin hooked it in the EXP GDC...and voila!! Hotplug and everything fine. I still need the 8 pin to hook it up into the GPU since it wouldn't run with all it functionnalities (PhysX, CUDA..). Credits to you @Uftherr #2 edit: went today to buy an aditionnal molex PCI-e 6pin and a molex adaptor 4 pin, now everything is fine and I like that blue light.

I took pictures but the quality is very bad. I would like to know if someone managed to get a EXP GDC setup with a PSU. There's something weird and I maybe am going to say something dumb. The 4 pins from the ATX adapter is "inverted" of the EXP GDC. Now imagine a key (4pin of EXP GDC) that should enter a lock (PSU 4 pin), you managed to enter the key but not as it's supposed to be but upside down, making the whole crack ----> burn. I'm not sure if it's supposed to be this way but I'm suspecting something with the 24 ATX pin adapter from the EXP GDC. EDIT: Ok some pics (qualitu is the poorest ever made) http://www62.zippyshare.com/v/88018383/file.html http://www62.zippyshare.com/v/5636501/file.html

@Uftherr Thanks. Actually I tried what you said, hooked everything up, turned on the laptop, the PSU and GPU fans spinned for 1 sec then stopped. I think something might be wrong with the the EXP GDC itself. EDIT: Ok, it seems that it was the ExpressCard that wasn't inserted well, now I have a blue light and fans are spinning, changing switches make fan spin more or less fastly BUT nothing is detected. No GTX on GPUZ, no Nvidia Control Panel...Anyone some help? EDIT: ExpressCard seems fine actually, I need to put the switch on the other position BUT and this is a big but (no joke on words lol) the 24 pin which is split between a 4 pins and 20 pins had some issues: the 4 pins began to BURN!! I turned the whole off and now I'm a little worried to continue the setup. Also, the card isn't recognized yet.

Hey guys, I went for the EXP GDC to give it at try, came today after 10 days o_o, anyways, I have NO idea on how to make the whole thing get working. I have a 350W PSU, and with the PE4L, there was the 24 pin to power on/off, here I have nothing so I'm wondering if it's even feasable?

No worries. Yes the other versions don't work I don't know why but as long as you manage to do the DSDT, it doesn't really matter.

Glad I could've helped. Keep the update.

Mmh I'm running out of ideas sorry. A last try could to be to download this version of iasl. If no effects please wait for someone else to provide some help.

Make sure you open Cmd prompt as an administrator.

Just copy paste the URL http://download.microsoft.com/download/2/c/1/2c16c7e0-96c1-40f5-81fc-3e4bf7b65496/microsoft_asl_compiler-v4-0-0.msi and the download will start.

Ok, so fist thing you'll need to download these two files Zippyshare.com - iasl-win-20120620.7z (iasl) http://download.microsoft.com/download/2/c/1/2c16c7e0-96c1-40f5-81fc-3e4bf7b65496/microsoft_asl_compiler-v4-0-0.msi (ASL) Then follow this video tutorial .You'll need the following to be pasted into your DSDT.dsl table: QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x0000000000000000, // Granularity 0x0000000C20000000, // Range Minimum, set it to 48.5GB 0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB 0x0000000000000000, // Translation Offset 0x00000001F0000000, // Length calculated by Range Max - Range Min. ,, , AddressRangeMemory, TypeStatic) Be sure to past it at the end of all the DWords of the search "Device (PCI0)" of the extracted DSDT.dsl table you have. Once finished just load the table with the asl command. Follow both this http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D.html#dsdtoverride tutorial and the video link and you'll be done.

I guess you'll need a DSDT override. What's your OS?

Yeah, they really need to look after it since it's one of the biggest feature against AMD.

Have you tried to plug and see what happens? Post more details please.

I deleted the old PhysX software, installed the new ones, but I still get FPS drops to 20 FPS at "high" and 40 at "medium", same as before. I think I'll just stick with "low" or "medium".

Yes I do. I'll try again without PhysX or on low. EDIT: Well, turning PhysX on low solved somehow the FPS drops. They aren't as frequent and strong compared to when it was on low. Thanks again @jacobsson.

I'm having lot pf FPS drops with my new GTX 770. I'm not sure why. I should be able to run games as borderland 2 at decent frames but nope. I'm suspecting the PSU not giving enough power.

I bought today a GTX 770 (yay!) to upgrade my 660. But I'm getting the error code 43. Anyway to get rid of it? Edit: Managed to make a DSDT override by turning testsigning on. GTX 770 recognized in Device Manager with no errors but all computing is disabled (PhysX, Cuda, OpenCL). Mmph...I'm close but I feel completely lost. I'm doing a clean driver reinstall and will see what happens. Edit: It appeared that power cables were loose..Everything is fine now, I'm doing some tests and post soon enough. Ok, benchmarks: 3DMark11: 7448 http://www.3dmark.com/3dm11/8336879 vs 5666 with GTX 660, very good. 3DMark06: 17610 http://www.3dmark.com/3dm06/17594930 vs 19911 with GTX 660. In Crysis 3, welcome to the juncle, everythin on max, 4xMSAA, barely drops below 30 FPS, so it's quite an impressive GPU.

Looks neat. Mmh was looking to buy EXP but I'll wait untill I see their finished product. Hope they improved the cable to make it a complete operational product.

@jacobsson what is the length of the cable of the EXP GDC? I find it so sexy, I might actually purchase one.

I'm really sorry for you. Please if you have the occasion to test your gpu on a desktop or the PE4L with another GPU to determine what hardware can be faulty. It's a painful process but we need to investigate all possibilities.

Increase in minimal FPS are very welcome indeed, I've tested it on Sleeping Dogs and FPS never drops below 30 FPS on Max Settings. Not bad. Didn't test BF4 yet. EDIT: Crysis 3 Welcome to the Jungle, Min FPS 25, +10 FPS from previous driver. :encouragement: Edit2: BF4 is capped at 60 FPS, never dropped below that. That's impressive.
