Once switched the BIOS setting "Express card" from "Generation 2" to "Generation 1", once it worked like clockwork. Prior to this, even with the card GTX650ti constantly blue screen, there was no change to eGPU and had some problems. P.S. By default, the BIOS stands "Generation 1". I do not know why I switched it before all experiments eGPU.

After removal of the reduced section solution really is . Thank you! But the results yet . All variants of the two laptops and two cards as eGPU working combination has yet been found . I suspect that the option of HP EliteBook 8470p AMD Radeon HD 7570M + PE4H-EC060A V3.2 + Radeon R9 270 can not fly at all , as only a bunch of possible AMD dGPU + AMD eGPU. Driver for mobile card card driver kills eGPU and vice versa. Featured previously leshcatlabs.net . drivers designed for ligament Intel + AMD and AMD + AMD I normally do not get up . I've already done DSDT override the main laptop HP EliteBook 8470p and PCI compaction-> Run compact. But drivers are not normally two cards AMD has not risen. I hope to score a bunch (after DSDT override) HP Probook 4530s + RADEON HD 4870 PE4H ( or Radeon R9 270 ) disabled dGPU, working with iGPU and eGPU? Frankly , this configuration is weak and does not suit me . I'm starting to think that you have to buy the card Nvidia ( eg GTX650ti, she climbs into my box PE4H-EC060A V3.2) and forget about the AMD cards in eGPU as a nightmare ...

Thank you for your attention to my problem. I could not follow the steps to remove the section "PCI BUS" in the file devcon.txt. I do not find this topic. The following recommended steps lead at the result: "The solution is not found." Here's a link to the diagnostic information.

All attempts in the section "PCI compaction-> Run compact" lead to post "not found a solution." Error 12 is not resolved. Maybe the reason is that Win7 is not English? SCN000.BMP

I took the opportunity to return Palit GTX660 card for testing and first saw the image on the connected monitor. But the design of the chip card GTX660 powered top makes the idea PE4H useless. Housing is not closed and all weakly secured. I will continue to try to run the AMD products. All hopes Setup 1.3

Greatest success - error 12. And HP EliteBook 8470p configuration graphics card AMD Radeon HD 7570M + PE4H-EC060A V3.2 + R9 270, and in the configuration of HP Probook 4530s with RADEON HD 4870 card in the device PE4H-EC060A V3.2. I can not get rid of the error when compiling a file with the extension DSL to a file with the extension ASL! Please suggest whether to be relieved of my file dsdt.dsl errors? If not here, then where can I get help? Thanks in advance! P.S. If DSDT correction does not solve my problem, please confirm that only Setup 1.30 solve my problem. dsdt.zip

Thank you! I work with Win7. I will try the proposed solutions and be sure to tell about the result.

Good day! I have a laptop HP EliteBook 8470p (B6Q22EA) with a graphics card AMD Radeon HD 7570M PE4H-EC060A V3.2 (PCIe x16 Adapter) + 2Gb DDR- 5 Sapphire <radeon r9="" 270="" dual-x="" oc="" with="" boost=""> (RTL) DualDVI + HDMI + DP + Crossfire When connecting PE4H put R9 270 driver , after reboot AMD Radeon HD 7570M works ( with discharge resolution and color to a minimum level ), and R9 270 is shown with an error in the hardware manager . Please suggest whether this configuration is buildable , AMD Radeon HD 7570M + RADEON R9 270 ? I think they clash at the driver level . Decide whether to use the problem Setup 1.30? Or simply consider purchasing GTX660 ( for example) and this card will work without problems? P.S. Instead tried to use RADEON R9 270 RADEON HD 4870, also use a laptop HP Probook 4530s with integrated graphics card and switchable ATI - the result is negative . If you disable the ATI card on HP Probook 4530s with the card RADEON HD 4870 PE4H I got 12 errors , but the attempt failed DSDT correction (I can not get rid of errors at compile ) I'm sorry for my english </radeon>
