@Swung Huang, I am a linux user, mainly using ubuntu based system, can you help me to test under ubuntu 18.04 LTS, with nvidia driver 410 and CUDA 10 installed, can the eGPU still works?
This does not entirely answer your question, yet on my Ubuntu system (Kubuntu 19.04, Vega 56 graphics card, external monitor, Mesa video drivers) Gerald's card (the revised version which allows AMD GPUs to be used without replacing the BIOS) works perfectly. I had less luck with Manjaro, which caused the system to slow down if only the external monitor was used.

I am considering installing the unlocked Bios in order to disable hyperthreading. Does anyone know if the unlocked Bios would, indeed, allow me to do so?
Currently I've set a Linux kernel option to disable hyperthreading, but apparently using the Bios to do this gives slightly better performance. -

Lenovo Y510p have diffirent story, since it's have got iGPU.
Ah, I see. I wasn't aware they'd completely disabled the iGPU on the Y500.
@Swung Huang - wouldn't using OCulink create overhead and thus reduce the maximum performance of the GPU? -
Surely this is not so bad? Or is there an application which you need the 650M - rather than the 1080 or Intel graphics - for?

* I am not sure how easy it is to drive the internal monitor using an egpu solution like the one you describe. You can do so using Geralt's adapter in Linux, and there is speculation about using High_Voltage's modded BIOS to more generally enable support for the internal monitor in this thread:
I have not tried this modded BIOS myself, though, and haven't used Windows in a while.
* Using an SSD will likely improve loading times, yet it should not improve your FPS in any way.
* The i7 CPU holds up well in my machine, but I have no experience using an i5.
* If you have the budget, get two RAM modules of the exact same size and type as this may help with performance.-

does we simply have to open the computer case, remove the dvd drive (unscrew?) and then plug in this gerald adaptor to complete the hardware installation?
To free up the slot which Gerald's adapter plugs into you would, indeed, need to remove the DVD drive, should you have one in your Y510p.
In addition to the adapter itself, you will also need a PSU able to provide your graphics card with sufficient power and, of course, the graphics card itself. -
Yes, that does look beautiful! I certainly do not have the tools to make such a thing myself, but perhaps I could find someone who could make one for me.

I've been going crazy looking for that bay extension you guys have.
Contact the OP. He may still have one available.

I am using an empty HP ink cartridge to prop up my Vega 56, which works really well.

Yours is almost certainly version 2.
Three versions of the Y510P Graphics Adapter exist:
* Version 1: this is the experimental version which Gerald originally posted about.
* Version 2: this is the version that Gerald sold in 2016 and part of 2017. It requires BIOS version 2.07 and Windows 10 to function. Earlier BIOS versions may also work.
* Version 3: this is the current version. Thanks to a discovery first posted to the forums by user David 'Soap' Washington, it should work with any BIOS version, as long as one uses an AMD graphics card rather than an NVIDIA one. It may also work Windows 7, 8 and 8.1, in addition to Windows 10.
To use an NVIDIA card you of course need the BIOS mod discussed in this thread. -
I see that you've been promoted, so you should now be able to download files.

Hey not sure if anyone was wondering if I got my setup working again, but if you were here's the skinny.
Turns out that my GTX 780 got toasted by a bad PSU.
Got me a new PSU and joined the Red Team with a Sapphire Nitro+ Pro Special Edition RX580 (It's blue!)
Now it's working waaaay better than my old card- no surprises there.
Also, is it just me or does the Radeon software look miles better than GeForce Experience?
Sorry to hear about your GTX 780!
I like the Radeon software, especially since it doesn't require you to sign up to NVIDIA's telemetry programme. -
Yes, that happened to me too, once it got to 60% or so. When I rebooted Windows marked the battery as fully charged, by the way. A quirk of the OS, it appears.
-
OK, so I discharged the battery to 33%. It then took almost two hours for it to go up to 99%. And then it got 'stuck'. That is to say, it never actually got to 100%.
There's no longer any indication of how long it'll take for it to 'fully charge', either: the text is '99% [space] until fully charged'.
Apparently, then, the OS doesn't quite know at what point to say that the battery is 'full'.

Doesn't happen to me. It just says 100% charged (which is correct; this laptop is always plugged into a socket). I use the latest BIOS provided by Lenovo, unmodded.

With Nvidisa HD 7950 is funcionless
Hey Kuneroll,
Do you mean the AMD card does work, and the NVIDIA cards don't?
-
Sounds like you're trying to carry out some form of file recovery. In any case, this doesn't sound like a problem caused by your hardware. It is possible for a hard drive to be damaged, but from your post it appears that the file just wasn't saved properly.
From my experience, OpenOffice/LibreOffice is sometimes better at fixing files made by MS Office than MS Office itself, but otherwise I am afraid the best you can achieve is some sort of partial data extraction. It is worth knowing in this context that xlsx files are really just renamed zip files which you can open with programmes like 7Zip and the Windows explorer itself.

You're welcome!

You don't really need the Lenovo drivers anymore. Windows 10 will recognise most, if not all, of the components. You can also download drivers from individual vendors, such as NVIDIA and Realtek. Just make sure you download the versions made for the components used in the Y510P.
-
First post updated to reflect the fact that solutions allowing one to use NVIDIA cards with the adapter have now been found.

Right! Who's ready for the next portion of cool things?
This time it's the hardware mod I was talking about a while ago. In theory, it should work with all the Ultrabay models including Y500/Y400/Y410/Y510p WITHOUT THE NEED TO MOD YOUR BIOS! So far, it worked on my Y510p. Looking forward to future tests.
I know, "hardware mod" may sound scary, but please consider this option too! Actually, it is beautifully simple!
It's so simple that I'm not even sure whether it needs a separate topic!

Excellent! I'll modify the Y510p adapter configuration thread to incorporate information about your BIOS and hardware mods over the weekend.

All of this is cool, but are you really able to use the AMD GPU as a graphics acceleration device when gaming in say "internal screen only arrangement"?
OK, I tried this out, and it appears that if I use the internal laptop screen only the laptop reverts to using the Intel graphics chip.

My (K)Ubuntu system detects the GPUs on my Y510p just fine, yet I haven't found a way to switch between the two dedicated GPUs (built-in and egpu).
I have therefore disabled the built-in NVIDIA card (755m) in the BIOS, which allows me to activate the egpu (AMD Vega56) for specific applications by using the command DRI_PRIME=1.
