      Hello to all dear visitors, 
       
      I have been using Lenovo y510p notebook for two years but in games I think my graphic card is inadequate. After that I've bought Mini PCI-e EXP GDC and attached it to where the wireless card socket is.  However because it has x1 speed its performance is too low. Even though on tests rx460's ranks is low than rx480, it has more performance.
       
      In x1 PCI-e port, the performance is too low and inefficient. On GPUz programme, use of memory controller is 20% but use of GPU is 100%. I mean, I've been hooked to the x1 speed.
       
      Components : EXP GDC version 8.0 +450w PSU + rx480
       
      I've read all pages about ultrabay, I want to buy and to share in forum.
       
      If anyone has ultrabay to PCI-e port, I want to buy. Please help.
       
      Thanks for everything.

      Hi, I'm having problems trying to connect a GTX 750 Ti to my Lenovo T420 using the dock EXP GDC Beast (express card version).
      My laptop: Lenovo T420
      RAM: 8GB DDR3
      CPU: Intel Core i5 2520M
      GPU: Intel HD Graphics 3000
       
      My problem is: if I plug the express card and I turn on the laptop it doesn't boot up and the screen becomes horrible, with coloured pixels and a sound like "bip-bip".
      If I try plugging the express card when the laptop is already turned on it sees the gpu, but if try installing the drivers I have to apply the modifies restarting the computer.
      I hope you understood my problem (I don't speak English very well).
      Please help me, It's making me crazy!
       
      EDIT: I didn't say that if I plug the express card when the pc is already turned on, in the device menager there is "Error 12" on the gtx 750 ti

      Hello,
       
      I have a lenovo y480 trying to set up exp gdc with mini pci-e. I followed the instructions to the letter and still my system does not detect it. graphic card i am using is a evga 1060 and windows 8.1   I am willing to upgrade to win 10 if that would make it easier, just looking for some guidance since i am a beginner at this.
       
                                                                                                                                                                                   Thanks

      Hi All,

      I'm trying to setup a eGPU rig -  but no matter what I do I seem to be running into the infamous error code 43.
       
      My setup:
       
      Thinkpad X220 i5 2.5GHz, 16GB ram (2x8GB @ 1600) Modified 1.43 Bios EXP GDC V8.4D PCI-express Sparkle NVIDIA GeForce GTX680 Dell DA-2 power supply  
      Seemed like a common setup from what I could read before attempting the build, so I wasn't expecting any specific troubles. How wrong I was...
      Steps I followed:
      Connect GPU and power plug into GDC, plug express card in laptop while power off Power on the laptop, GDC starts fine, generic VGA adapter is detected Install nvidia drivers, reboot Card shows up, but with error code 43  
      Sometimes I'd get a blue / black screen of death, and changing the PTD switch to 14s would fix this, but error 43 would still be present. In both cases, hot-plugging the card would work fine - it gets detected in the device manager, but the error would be still there.
       
      I had a few times where I got error 12 instead, so I went to the BIOS and changed the TOLUD to 3GB as suggested in some online discussions. That fixed error 12 but would just show error 43 again after reboot.
       
      I read it might be a driver issue (although people said it should happen only with the new 10xx series of cards), so  I tried several versions of the drivers: latest, 375.64, 372.70, 372.54, but with no luck.
       
      Here's a list of other stuff I tried by reading about other people's successful setups / troubleshooting experiences and looking for error 43 related threads:
      Setting PCIe Power Management off / on in the bios Setting PCIe speed to gen1 manually Enabling / disabling hotplugging for the pcie interface the card is installed in  
      But still no luck. Going crazy over this. Has anyone been in a similar position and can offer me advice? Thanks!
