  1. Could you please make a video of your beanchmarks between the default GPU (GT 755M) vs the R9 Nano (with a mPCIe adapter and your ultrabay adapter), and upload it to YouTube? That will get more Y510p owners impressed, and definitely increase the demand of your adapter. Also, as somebody already told you: I think that your UltraBay to PCIe 3.0 x16 @ x8 adapter is amazing, but this will add stress to the Y510p motherboard because of the weight of a desktop VGA attached to it, and many people (like me) use cooling pads, so it will be a little complicated to use the laptop as regular... So, what about a cable solution too? I mean: Your adapter can end in the edge of the laptop (as long/large as the ultrabay compartment), and then we can use a PCIe x16 extender cable, but this solution wouldn't be much flexible like the cable that uses the mPCIe adapters (looks like an HDMI cable). As far as I know, concerning the physical layer of the PCIe (electrical pinout): PCIe x16: 164pins (2x82), with 6 pins not connected, and 68 grounds that can be a single wire, right? PCIe x16 @ x8: 164pins (2x82), with 39 pins not connected, and 68 grounds. This will require 58 wires, right? <- your adapter. PCIe x8: 98pins (2x49), with 4 pins not connected, and 37 grounds. Although the wikipedia page doesn't match exactly with the interfacebus.com one (11A, 12B and 82B)... I think that the idea would be the same... Something important too: the impedance of the cable... and as the signals are differential pairs (2 pairs per lane), I suppose that this would require a cable with at least 17 twisted-pair wires for x16 @ x8, (8 lanes + refclock diff signal) and 24 simple wires... Anyway, I didn't saw again any electronic design since I graduated from the university (6 years ago), so it's sure that somewhere I'm making a mistake or forgetting something important... Again, great job man! I'm interested in your adapter. P.S.: Sorry for my bad english.
  2. Great job, man! I was looking for something like your project for a while, I was planning on doing eGPU through the mPCIe (Wifi card), but then I realized: "wait, this old laptop has a Ultrabay port, so let's take a look, someone must have done something with it". Do you plan on mass manufacturing and selling your Ultrabay adapter? Or something like that? I'm an electronic engineer too, but I've specialized on industrial control & automation (PLCs, SCADA, DCS...).
  3. Ok, I have a question: Is there a way to overclock the "Bus Speed"? I mean the 100 MHz clock, because I have it on ~99.8 MHz.
  4. I have a Lenovo Y510P-20217 (GT 750M no SLI), with the 347.25-notebook-win8-win7-64bit-international-whql drivers... As I can understand from this thread, I can't longer overclock the VGA, but with NVIDIA Inspector I can still do it. So do I am getting this thread wrong? P.S.: Sorry about my english.
  5. First: thank you so much for this tool! I'd like to know if there's a way to have two speed profiles: I mean, a slower speed at 55°C and faster at 80°C.
  6. Take a look at this mod: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Y510p-Ultimate-Cooling-Mods-Revealed-Unshroud-your-cooling-fans/td-p/1533688

  8. I found this: NVFlash download version Inside the zip, you'll find three folders: \Linux \NVFlash <-Look here for the DOS version. \NVWinFlash
