metallus84 Posted March 4, 2017 Share Posted March 4, 2017 (edited) System details: System: Hardware HP ProBook 6560b Core i3-2310M 8GB RAM (4+4) iGPU Intel HD 3000 Software Win 10 Pro 64-bit Additions: Hardware nVidia 760 GTX GAINWARD Phantom EXP-GDC v8.4d Express Card version 650W ATX PSU Software Latest nVidia and Intel Graphics Drivers ******'s DIY eGPU Setup 1.3 DSDT Editor + Compiler pack Boot sequence Hardware All systems off/offline EXP-GDC Delay Switch set to 6s delay Position 1 will cause BIOS freeze/lockup ! Self-made from half cutted HMI cable and empty ExpressCard34 slot with EMC ferrite filter on one end This allowe me STABLE PCI-e 1x 2.0 connection (GEN 2 5GT/s) without know freeze due to bad original cable PSU powered on Laptop powered on All systems on/online Software Update BIOS to latest version On power on, hit Esc and enter HP BIOS Config Set boot mode to Legacy (Not UEFI or Hybrid) Set ExpressCard slot speed to Gen 2.0 (or higher) Save and exit/restart Windows is running in Legacy mode/MBR disk Uninstall any previously installed graphics drivers from Programs in Control Panel Use Display Driver Uninstaller to clean up any previously installed graphics drivers Install nVidia graphics drivers Device manager now shows the installed 760GTX, but with Error Code 12 (Insufficient free resources) Perform a DSDT override. Refer to this topic where i took information for mine: Install ******'s DIY eGPU Setup 1.3. Preferably, extract the files and write to/setup a USB stick. Boot from the flash drive and install. Configure as needed https://www.youtube.com/watch?v=HC99rJOtioE Make sure mbr is used instead of mbr2 Save startup.bat Reboot into DIY eGPU, and load startup.bat Then chainload into Windows 10 nVidia Control Center must now be active and the graphics card is ready to run games, CUDA applications, etc No big issue till now, very happy to made a self soldered HMI cable that allow me to work in GEN2 ExpressCard mode (GPU-z tell me PCIe x 16 2.0 @ 1x 2.0 during 3dMark and Fraps benchmark) Performance 3Dmark 06 10143 (SM2.0 4079, HDR/SM3.0 5030, CPU 2507) 3Dmark 11 P 4862 http://www.3dmark.com/3dm11/12025228 3Dmark (steam DEMO version) Firestrike 3886 (24.81 FPS Gt1, 20.92 Gt2, 8.7 FPS Physx, 7.9 FPS Combined) Icestorm 22488 (98 FPS Gt1, 98 FPS Gt2, 71 FPS Physx) Unfortunately i have bad performance on benchmark (except Firestrike) if i made a comparison also on this Forum with other systems. I don't know if Opt1.2 use pci-e compression through HD3000 or is just a CPU limit that i reach. All test are made on internal lcd only (that is my focus now). Does anyone idea why? Any suggestion?

alternal_steam Posted March 8, 2017 Share Posted March 8, 2017 Yeah, your processor is the weakest point in the system. The best performance for egpu provides i7 Quad Core. You should think about CPU upgrade. You posted benchmark results - you tested on external screen (attached to egpu) or on internal screen of your laptop?

metallus84 Posted March 9, 2017 Author Share Posted March 9, 2017 I am interessed only on internal display. But if i use external one should i have maximum performance (so limitation is sure CPU related?). Can i use this data to see if HD3000 compression is disabled or not?
