Hi, I have a ThinkPad E420 with Zotac GTX 560Ti as the eGPU. I have no problem with PCI compaction using eGPU Setup. I don't see any message in the Windows Device Manager saying the device has problems. However, when I try to user the external monitor, I always get the message saying external monitor is not detected. What could be the problem? Regards, Haris

Well to purchase PE4H was a wrong decision indeed. I knew about eGPU for the first time not from notebookreview / techinferno forum and there they recommend PE4H instead of PE4L. I just knew PE4H only support G1 speed recently. How careless I was. I have tried to set G2 link but I couldn't connect to external monitor. No error 12 though. Do you suggest that I replace my PE4H with PE4L 2.1b?

Try to set the eGPU PCI port speed to G1.

Hi, My eGPU stops responding (and external monitor disconnected) at times not only when playing games but also when only displaying desktop (GPU load is low). I've tried to lower the GPU shader / memory / processor clock using Zotac Firestorm but it didn't help. I'm pretty sure it's not the PSU since I've used my eGPU to play demanding games in ultra settings. GPU-Z shows GPU load reaches 99% all the time. Can you give me some suggestions? I'm using Lenovo E420, PE4H, Zotac GTX 560 Ti. Thanks in advance.

PE4H isn't Gen2 capable? I bought the wrong product? Nooooooo! I should have read thoroughly before purchasing. My eGPU load is above 90 % all the time when playing games & the egpu fails at times even when I use it not to play games. Are you sure it's the PSU that causes the problem? (...oh God please not another wrong product )

Hi All, My laptop is Lenovo E420 and my eGPU is GTX 560 Ti. My eGPU is stable if I use the G1 speed. Every time I try to use the G2 speed (from eGPU setup), the external monitor shows nothing and I can't connect to it. There is no error12 though. What could be the problem? Also, my eGPU stops in a sudden at times and I receive an error that says "the display driver stops responding and has been recovered". Could this be the mini HDMI cable?

Hi, Sometimes my PE4H stops working all in a sudden and I get a message something like "Display driver stopped responding but has been recovered". Is this a symptom of bad mini HDMI cable? If so, will replacing my cable with 2 mini HDMI to HDMI converters and a HDMI cable (not mini HDMI) work?

You may try these steps to prevent BSOD, it works for me: Those are steps in Lenovo E420 & GTX460. It might work with your laptop. You may also try to set the eGPU PCIe link to G1 speed before running compaction.

But you said earlier that PE4H is only stable if it runs on G1 speed.

I live in Indonesia and HIT doesn't ship to my country either. You may want to contact Nando for the details of how to get the software.

Hi All, I have some noobish questions: 1. How do I know I'm running on Optimus compression? I'm using Zotac GTX 560 Ti. 2. My eGPU works on G1 speed. If I want to run it on G2 speed, what should I do? My laptop is Lenovo E420, with Intel i5 2430M, HM65 chipset. 3. I'm testing with GPU-Z and the GPU load reaches 99% all the time. Is this normal? Many thanks in advance. Regards, Haris

It works! Thanks a lot! These are my steps: 1. Set expresscard slot to run at Gen1 (PCIe ports->Link speed.G1) 2. Run PCI Compaction (32 bitA) on iGPU 3. Chainload mbr 4. After Windows starts, external monitor shows nothing yet. Go to 'Set screen resolution' in control panel. There are 5 monitors available there (I don't know why). Choose display 4 and then choose 'extend desktop to this display'. 5. My eGPU is ready to use

Hi All, My PE4H has finally arrived but now I'm having trouble with the DIY eGPU setup. I don't know what else to do. My laptop is Lenovo E420 with i5 2430M, Intel HD 3000, 8 GB RAM. My eGPU is Zotac GTX 560 Ti. I use an old Simbadda 380W PSU. These were my trial & errors in DIY eGPU setup: 1.a. Run Compaction (32 bitA) > All PCIX Ports. Result: system froze before compaction finish 2.a. Run Compaction (any method) > eGPu & iGPU 2.b. Run startup.bat 2.c. Chainload mbr Result: Error 12 in device manager 3.a. Run Compaction (any method) > eGPU 3.b. Run startup.bat 3.c. Chainload mbr Result: Error 12 in device manager 4.a. Run Compaction (any method) > iGPU 4.b. Run startup.bat 4.c. Chainload mbr Result: No more Error 12 in device manager, but system froze when I right clicked on desktop wallpaper / set up screen resolution from control panel. Also, nothing was displayed on my secondary monitor before my system froze 5.a. Run Compaction (other than 32 bitA) > All PCIX Ports. 5.b. Run startup.bat 5.c. Chainload mbr Result: Error 12 in device manager 6.a. Initialize iGPU (or also eGPU) 6.b. Run Compaction (32 bitA) > iGPU (or eGPU also) 6.c. Chainload win7 Result: No more Error 12 in device manager, but system froze when I right clicked on desktop wallpaper / set up screen resolution from control panel. Also, nothing was displayed on my secondary monitor before my system froze I always used to run startup.bat since it seemed the only way to make the compaction takes effect. I'm not sure though. What else should I do? Many thanks in advance. Regards, Haris
