That would be great, but I can't send you a private message, your inbox is full If its the one will the 3.3v pull up I tried shorting it to GND by inserting a large metal pin in the port (since there are two GNDs below that pin and its the last pin), but maybe I didn't get a good connection. you should try again, update us

can you post more pictures of the build (adpaterto GPU connection)

So maybe we need to enable USB3.0 mode with those mod pins (MOD_MD, MOD_SATA_PCIE#_DET), and I tried one of them. And those lanes are direct to CPU, can those be disabled by PCH for example? If I didn't wreck the ODD port, I would have gotten USB3.0 module, it's probably PCI like you say and will provide the correct connector.

Is there anything else needed for x2 besides TX/RX and GND from module bay, TX\RX\GND from express card, and control signals from express card port that might cause it not to be detected/enabled? like shorting PRSNT pins on 16x connector? using module bay PE CLK REQ or PE RST? BTW how is the USB 3.0 module bay expansion module gets USB 3.0 from SATA/PCI-E? can we get a close up of the connector?

Cool, I talked to nando in private about having a thin pcb/socket that sits between the CPU and the CPU socket to get PCI-E signals, and even about soldering to broken GPU Dell Inspirion 5110, and then this thread pops up. Good luck.

oh why didn't they add HDMI ports for another 3 lanes :|

heh, I meant how are you gonna test port 4. soldering? which bplus/GDC adapter? I guess will see anyway.

awesome, how?

Have you confirmed that port3 is set @ x2 mode? If you own Setup 1.x or any other program that can check, make sure that port 1 and port 3 are set @ x2 mode (port 2 WiFi would be disabled). Yes that's how I connected it, and it's the same riser image I used. It seems the orientation for this schematic is as if looking ontop of a desktop motherboard female slot (the risers has VCC 12v (B1-B3, A2-A3) tied together so I assume its correct). I have setup 1.x which confirmed its x2 on port 3 (I did it x2 on 1-4, 5-8). maybe flashing back the restricted descriptor since it has strange effects on audio and stuff.

Can you post the ME firmware, his guide isn't really clear.

rightmost two pins of the SATA(?) power are GND, assuming pins 12, and 13. adding that pin 31 is connected to a 10k resistor (R1183), assuming the one in the picture which I measured to be 9.8K, and the resistor on its left also measured 9.9K going to MOD_MD pin 11 near the two GND I mentioned of SATA(?) power. So I'm guessing the count goes from upper part left to right 1 to 13 and then to lower part left to right 14 to 31. So I assume I got the pins right. Here's one of the connectors: as you can see its has pins on top and pins on the bottom, its divided (top/bottom) like in the groups in the schematic JSATA2 with the same pin count. The right plug was a SATA L shaped female I destroyed. It's top was a normal SATA, it just has extra 11 PCI-E pins on the bottom that touch the plastic (don't connect) if its a normal SATA male connector since its they are one sided pins. Why is there even PCI-E on this port? I can't find any dell equipment that uses the module bay for PCI-E. Maybe a disassembled displayport/HDMI connector (without the casing) might have the correct spacing and fit (might add some buffer as it seems a bit thinner), giving us a high speed shielded cable right to the port? Display port HDMI:

That's what I did, port 3-EC to PE4L and a RISER to the GPU, and soldered another lane of the riser to port4 module bay using a SATA cable (GND, RX, TX). [[bTW there are also PCI-E clock signals on the power part, again upside down of the normal power plug]] Yes, but isn't that port combo a PCI-E + SATA, where does the USB come in. Its possible I've got the pins wrong especially the pairs themselves but I was using a multimeter, the fact the RX lines has capacitors on them, and double GND between TX and RX which isn't between TX and CLK (and pin count). I'll get a picture but I destroyed the port for easy access. Might not been the best soldering but its just a test. And just to check, PCI-E connection is RX to RX (+ to +, - to -) and TX to TX right? not cross?

I can't get module bay PCI-E to work with express card using PE4L + RISER and show in GPU-Z. Using the two GND lines and RX lane capacitors as "polarity" I think I identified which is which (GND, RX-, RX+, then two GNDs, TX-, TX+, GND, REFCLK-don'tcare, REFCLK-don'tcare, GND) from the other side unless they go in the connector not in this order, the schematic just shows it as a long port, so maybe the +, - are switched. Then I soldered a SATA port I took from the disk drive (it has a SATA to flat connector inside) to the module bay, and using a sata cable to connect to the riser (RX+ to lane2 RX+, RX- to lane2 RX-2, TX to TX... and one GND which I soldered to one of the other lanes since they are all tied. Soldering seems ok with multimeter and impedance also seems fine. grounding MOD_SATA_PCIE#_DET pullup looks like just enables/disable USB3.0 somewhere, how is that related to SATA/PCI-E. Maybe someone should try 1x from module bay first.

Probably from another 3.3v source, Its very difficult to short 5 and 9 because the chassis is in the way. But pin 5 has a unattached pad about a cm near it away from the chasis but is easier, so you can supply 3.3v there. I just used a 3.3v from the big resistor on the other side. I wrecked the SATA/PCI-E Module bay to solder a SATA PORT (from the disk drive) to the ODD's PCI-E lane, but I can't get 2x (port 3) enabled to test it, Maybe I need to supply "MOD_SATA_PCIE#_DET" or "MOD_MD" something? Edit: Guess not had to shutdown not restart the laptop moving on to soldering a riser. Don't know if it were mentioned but the module bay is a PCI-E/SATA combined port, its a normal SATA connection on one side and on the same connector above it is PCI-E. If we can get a proper module bay connector (SATA like L shape connector but with 11 smaller pins above) we wouldn't have to tear it.

@timohour, @TheClassicalCat, I've applied high signal on pin 5, then I wrote a modified flash with read access and write access set to 0xFF. I restarted and now I can read the flash without applying high signal. But I can't write again! It says Error 280: Failed to disable write protect for the BIOS space! I can still read, but can't write even with applying high signal on pin 5. Any idea what to do? EDIT: ok I can write just the DESCRIPTOR which I modified in hexedit working! I've got a 2x port 1. Thanks.

@timohour, hey I've got a iGPU e6430, but I can't find the 92HD90B2X5 chip. It isn't in the same place. any thoughts on where it can be? can you take a better resolution picture for the text/pins on it. Edit: found it, its on the other side, had to diassmble entirely to find it since I missed it at first. Its harder to reach but I'll try to reassemble (its a mess!) and using a pin. thanks.

Isn't PCI-e lanes independent, each transmitters/receivers pairs should be the same length, but between pairs it doesn't matter if it within spec (https://www.pcisig.com/developers/main/training_materials/get_document?doc_id=6d37ec2f8543fc1f9d8ace6264d08b469f57e5f1) What I'm saying is that if one pair connection usually works, two, and four should too. Maybe a SATA cable will work for the other connections (just transmitter/receiver pair exactly as SATA).

here's another one from Gigabyte Amazon.com: Gigabyte Dual Ports DisplayPort 1.2 Capable with 4K Video Throughout GC-Thunderbolt 2: Computers & Accessories Is it the same?

Nice work, But that physics score :| Are you gonna get a 15" or stick with this?

Awesome!

maybe use a SFX PSU.

4k Should work fine if gpu supports it. And about games, Which games? I've tried some 1440p games with my 290x. Considering that about same game world is sent over the pci bus (in terms of draw calls, polygons, textures), unless the game actively sends higher detail/resolution for high resolutions (which more games this settings are detached from resolution) the difference is fill rate/shaders acting on more pixels intersecting the screen, and if fov is greater more polygons (less gets occluded and culled from the borders) will be visible. I don't think it will affect bandwidth much. So my guess is games that had a really high fps will work fine (you can probably disable AA) at 1440p, high fps will work fine in lower details. Basically the same performance drop ratio you see in desktop benchmarks. 4k Is a different beast and high end GPUs struggle with it. Bandwidth will not change much. 1080p game will look the same when the monitor is at such distance that the angular size (apparent size) is the same as your old/other 1080p monitor, but close up it will be blurry (depends on the game). Btw, You don't have to move the monitor much back to match the apparent size of a 24" monitor I forgot how much is it but its about 13cm back... (http://goo.gl/K6JSdD)

cool, how did you know it exists?

Awesome. Your entire setup is sexy Even your desk . Its a shame thunderbolt solution cost so much, it really shouldn't. Can you test 3dmark11 3DMark 11 - DirectX 11 video card benchmark from Futuremark, you seem to have provided 3dmark (the cross platform one) instead. And if you have bf3, bf4. Bf3 is much more bandwidth bound than bf4. And is that a QX2710 screen?
