SystemModel: Samsung RF511-SD1BR (brazilian, but similar to US versions)Processor: Intel Core i7 2630QM 2.00 GHzChipset: HM65Screen: 15.6’’ LED HD (1366 x 768)iGPU: Intel HD 3000dGPU: NVIDIA GeForce GT 540M 1 GB DDR3RAM: Corsair Vengeance 8 GB DDR3 1600 MHz (upgrade)SDD: Samsung 840 Pro 256 GB (upgrade)Has EC slot or Thunderbolt: NoHas mPCIe slot: Yes, internally, in which was a Broadcom WiFi cardExternaleGPU: Gigabyte Radeon HD 7970 OC 3GB GDDR5 – Core 1000 MHz, memory 1375 MHzAdapter: PE4L-PM060A 2.1bPSU: Corsair CX 600WMonitor: ASUS 23’’ Full HD IPSSetup• Did fresh install of Windows 7 x64.• Did all the power connections: notebook DC adapter, PSU floppy connector on the PE4L adapter, PSU 6-pin and 8-pin connectors on the eGPU. Also plugged the PSU 24-pin connector on the SWEX.• Connected the high-speed HDMI cable between the external monitor and the eGPU.• Put the switches on the PE4L to x1 (SW2 position 1-2) and 6.9s delay (SW1 position 3). Jumper J1 in place (default).• Opened the notebook and put it upside down, supported by the screen, for easy access of the mPCIe slot, which is only accessible by removing the bottom frame of the notebook. Using wireless keyboard and mouse now.• Turned on the notebook and booted Nando’s Setup 1.10b5 + updates, via USB flash drive.• Turned on the eGPU + PE4L via SWEX.• Plugged carefully the PE4L on the mPCIe slot.• Pressed F5. eGPU detected on port 1!• Did 32-bitA PCI compaction on iGPU + eGPU ignoring the dGPU.• Changed the speed of port 1 to 2.0.• I needed to ensure pci_alloc_valid was 256 MB. I only achieved this by removing 8 GB RAM (there was 16 GB initially). Oddly, pci_alloc_valid at 128 MB gave me low Vantage benchmark results, although no Error 12 was displayed.• Chainloaded Windows 7 and installed the latest AMD drivers (13.2 beta 5). Rebooted, doing the same steps to detect again the eGPU.• I don’t know why some benchmarks resulted so low, particularly 3DMark06. I tried exchanging drivers, disabling ULPS, changing settings in CCC, overclocking… Does anyone have an idea?Benchmarks 3DMark06 (DX9) 3DMark Vantage GPU (DX10) 3DMark11 GPU (DX11) RE5 (DX9) DMC4 (DX10, scene 4) Heaven (DX11) Battlefield 3 MP (1080p) Borderlands 2 (1080p) Portal 2 (1080p) iGPU 4563 1790 --- 34.5 27.07 230 --- --- --- dGPU 8588 4857 1120 63.1 61.33 609 20 FPS on Low 30 FPS on Low 30 FPS on Medium eGPU 11983 11925 11221 26796 26763 26456 8951 8950 8943 122.0 149.84 2618 2468 2303 50+ FPS on Max 40+ FPS on Max 200+ FPS on Max
