Hello, since you are new member i can't send you either pm,  https://ufile.io/z1yg5, the shematics from gerald, also note that you will need ultrabay adapters, (in my case i had ordered them but unfotunatelly the coustoms asked for extra 100euros i am from greecce, so i rejected the package, i had ordered 7 pieces , and thus i abandoned the project, however you're from states as i see so you wont have coustoms. If someone will create those adapters will gladly buy for me). Also you'll need the power pin adapter for power supply, and some transistors, resistors, capacitors, all these can be found if you google the product codes from the schematics, so i wish you good luck.

Why power pin adaptor is needed? Can we just simply connect the power cable from PSU to eGPU?

I think @Gerald talk something about it. I guess eGPU can't get power from Ultrabay (~75W via PCIe slot) and laptop board can't provide such power. SO, ePSU power eGPU from both sides: PCIe slot on adapter and PCIe power connectors.

 

P.S. I have no information how much power got second GeForce GT 650M via Ultrabay.

Sorry, to make it clear I mean plug in the cables from ePSU to eGPU directly without power pin adaptor. This is because I am planning to use GTX 1080 TI and it needs 8+6 pins, those sample in previous pages only has 8 pins.

Oh, your talk about diffirent design... My mistake. Probably in you case (with GTX 1080 Ti) you better to stick to original design.

 

But i think it do same job - powering PCIe slot.

 

I have got GTX 1080 Ti and i connected both 20-pins (in adapter) and 8+6 pins (in eGPU). Everything worked fine.

Hi everyone, new member here. Came across this site and topic by happenstance as I was considering to either upgrade or make a switch from my Y500. Decided to go for the former and am really amazed by what has been done regarding Ultrabay. I actually have not done any upgrades or modifications to this system at all, up until now when I replaced the 16 GB SSD. Interested to see the progress on the adapters here on the forums, as I most likely will not try to build one myself.

 

Now, to the topic at hand. Aside from graphics upgrades, I would also like to replace the WiFi card. Therefore I went ahead (despite not being eGPU ready) and flashed the BIOS with the mod provided by @High_Voltage:

Hi everyone!

 

Here's the experimental mod for Y400/Y500: https://mega.nz/#!qBYE0BLa!Nos2gBVE8-_eOX8O5bSyxSEjgOQ154QSu4BWnk6C3qc

 

It is also based on Svl7's work and should enable both AMD and Nvidia eGPUs for Y400/Y500. So far, @Swung Huang has successfully tested it with GTX 1070 on his Y400, but I'd be grateful if more people verified that it works for them. Especially, would be interesting to hear whether AMD cards work too.

 

If everything is good, I'll create the separate topic for this one too.

 

-High_Voltage

 

It seems to run fine, but something I noticed is that with the current WiFi card, once bluetooth is turned off it will not resume until system reboot. At least this is the case with my setup in Ubuntu 18.10. Reflashing BIOS to the backup I took prior to flashing with the mod solves the issue. Any thoughts on this? Have not purchased a new WiFi card yet, so I do not know if this issue persists with another card.

 

Sorry for going off topic, but I did not see a separate thread for the BIOS mod in question.

This is really interesting! The Y500 mod has not received much testing at all and is only used by a couple of people at the moment. I think this is because of the adapter being initially advertised as not compatible with the y500 series.

 

Regardless, the whitelist removal component of this mod is an exact copy of the svl7's original work for the y500, therefore it'd be a good idea to check his thread for similar issues.

Seems there were similar issues with no real solution, even after switching for another WiFi card. Will personally continue to check on this.

 

Returning to topic, I would gladly report back on the mod whenever I get a hold of an adapter.

Does anyone have the schematics for the 2199015-1 connector that can be imported to kiCad or any equivalent tool. It would be of great help if you can share the file.

Here's a schematic symbol and a footprint for KiCAD I've designed for my version of the adapter:

https://mega.nz/#!DIxnzA6B!cvIvt-ZVpfJ3FMkgPbybyGcQviCzwBhV4VY2x-eXk5A

 

Speaking of my ultrabay project, it's kind of stalled right now as my Y510p has been malfunctioning in a very strange way for a month or so, and I started to consider a PC build. Nevertheless, I'll still finish it at some point.

 

P.S. I haven't yet ordered any PCBs with this footprint, so it is unknown whether it has got any mistakes.

Thanks @High_Voltage it really helps, will start working on it and let you know if it needs any updates.

My adapter is soldered and currently not working. PSU switch is working, but GPU is not detected (PC working properly). I guess it may be some things which I made variable because the was difference between Lenovo's and gerald's scheme (like PWR_GOOD and PRSNT#1 pins).  I will try some combinations and do some measurements, hope I it will be it. 

Edit: Current configuration is by gerald's scheme.

Great !

 

nice progress. Hope you will figure out the solution 

 

Good Job

Hi guys little update:
My adapter still not working and I don't know how to find a problem.


I've tried @gerald's pins for PWRGOOD and that one in Lenovo schema nothing worked.
I am using 9800GTX for test run after normal boot PSU is switched on, but GPU is not detected and not giving any ouput.
Differential pairs are same lenght... Signals connected according to @gerald's scheme (without some resistors, which @High_Voltage suggested not to use).

Not sure what to try next. Maybe @High_Voltage have some sugestions.

Do you have a schematic of what you've built?

 

Double-check the pinout of pcie and whether all the signals are routed correctly. Check whether your Reset signal is ok. 

 

Also, did you use a high speed PCB and if you did, did you calculate RF impedance of the differential pairs correctly? I think it needs 100 Ohms per pair. Anyway, if the issue was in signal integrity, I would at least expect the card to be detected, so the problem is somewhere else... 

 

Also, are both 12v and 3v correctly supplied to the card's pcie slot?

Here is my schematic.

I will check 12v and 3v power supply and re-check RESET signal.  I didnt calculate RF impedance (that's beyond my knowledge - shamefully), but as you wrote if it was only about signal integrity I think card would be detected at least.

PS: Ultrabay connector has two pin numbers: one as in datasheet and second for Lenovo y510p schema (for easier orientation).

The schematic looks good. I can't see any mistakes. Have a look at your PCB and make sure everything is routed correctly. One pitfall I could think of is the footprint for eGPU PCI-E connector. When you look at it from the top, with that smaller section facing up, the B will be on your left, and the A - on your right, which is counter-intuitive when compared to the schematic symbol.

 

Another question is whether you've actually tested that GPU with another computer to verify that it works?

I think I have the footprint right, yes its other way than on schematic. But I draw it as it was in datasheet. 

Ye it came to my mind if it can be bad GPU. My friend told it work but guess I need to test it somewhere. I dont have any desktop at home.image.thumb.png.2140565393e72e5061f00442366765f2.png

Oh, I was talking about the connector that the gpu is inserted into, not the ultrabay one. 

Sorry. Yes I have checked that already, if signals really goes to right side and pin of connector. Now I will take a look on that GPU. Thank you very much for all of your advices. I will post some update as soon as I find some desktop where I can put my GPU.

Also, if you have a problem with fan pulsating/clicking on any modified bios then you can post your request in this thread.
       
      The flashing procedure include two steps:
      1.  Flash main system bios.
      2.  Flash EC firmware.

      Hi,
       
      I read a lot of different threads about the maximum possible M17X R2 configuration. But after I was more and more irritated.
       
      What is at the end the best performant GPU solution (with unlocked bios and dirver mod) but WITHOUT manual fan control and such things. Because if I want to sell one day my M17X R2 I don't want to explain and force the buyer to control the GPU fan per hand.  
    • By rusTORK
      When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
       
      I. ORIGINALS
       
      1. Forcecon (marked as FCN on fan)
      DFS5413005MH0T-FC1C (5V - 0.5A)
      Spotted in: Y400, Y500.

       
      2. Asia Vital Components (marked as AVC on fan)
      BNTA0612R5H-P007 (5V - 0.5A)
      Spotted in: Y410p, Y500, Y510p.

       
      3. Sunon (marked as SUNON MagLev on fan)
      MG60120V1-C230-S99 (5V - 2.25W (0.45A))
      Spotted in: Y410p, Y500.

      So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?

      Has any company out there launched a laptop with an external MXM port? 
       
      Just curious since with the boom in the gaming laptop market and some companies launching eGPU thunderbolt enclosures, isnt the MXM faster?
       
      Is it because of licensing issues? or hardware problems?

      Hello guys ...

      i wanna make sure that everything is going to work fine with my laptop so i got some questions

      First of all my laptop is Lenovo Z51-70
      CPU: I5-5200U 2.2ghz
      iGPU Intel HD 5500
      dGPU:AMD R9 M375
      Ram: 8GB (will raise it to 16GB)
      HDD: 1TB stock one
      SSD: 120GB (for my games and windows only)

      now i investigated  a little about eGPUs and found that i need a M.2 or thunderbolt, i've found that my wifi card use a M.2 a/e key aka ngff, so i will be using the GDC Beast NGFF version

      to the bad part / question part

      What do i need to know other than the stuff above?
      what is the white-listing thing? i found on support forums that my laptop support some wifi cards only and it's bios cann't be modified according to bios modifying forums (not here)
      in same time saw some posts on reddit that says if ur bios have UMA graphic option then you will need to disable PAX / WIRELESS and enable UMA and it will work fine, the question is that true?

      i wasn't able to find anyone who did it on Z51-70 i found only 1 post on reddit for Z41-70 (which after research found that both are using same M.2 a/e key slot and also same bios... but the one who posted only replied that it's recognized with some errors and never replied back with any updates so still not sure about it.....
