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?

Is there any particular reason why you are using the PE4H over the PE4L?

Assuming I am looking at the correct E420, you have a second-gen i-Series, therefore it should support PCIe 2.0 through your ExpressCard slot. It might be just me, but people who use the latest PE4L ver 2.1b have fewer problems on newer equipment that those who use the PE4H.

I cannot really help to fix your problem since I have the PE4L.

Maybe check in the Setup 1.x that you have established a G2 link (assuming it supports it). That alone helped the performance on my setup significantly.

Hopefully nando will chime in seeing he is more versed in this matter.

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?

HI Folks,

i got a Problem with my eGPU. I have a Notebook based on the Compal NBLB2 (i7, 4GB RAM, HD 5650M). I set up the PE4H + PM3N and installed Setup 1.x. The Device Manager shows my eGPU (430 GT) and there is no error. However i don't get a signal to my external Monitor. The Display Switching SHortcuts don't work(there just the Cursor mit this little circle shown for a sec.) In the resolution change menu is no graphic card detected and the Nvidia control panel tells my that i don't use a Display that is connected to a Nvidia GPU . I already tried to install the DNA modded drivers, but there was no change. Please consider helping me.

Best regards.

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.

Your PE4H isn't Gen2 capable. You need a PE4L 2.1b for that. The display driver suddenly not working could be due to the card being factory overclocked beyond it's capability (yes, it happens!) or the power supply being incapable of providing enough power to drive it. I'd suggest use MSI AfterBurner to lower the clocks and see if it solves the problem.

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?

Oh god i've been at this for a long time now!

I got a GTX 460 v2 running on PE4L on a sony vaio notebook with intel i5 560M processor.

If it doesnt recognize the card i set it to sleepmode and then power it on which gives me error 12. So then i restart my computer and everything shows up fine and i can use the card BUT it's laggy as hell. It's even performing worse than my dGPU (Geforce 425M) so i figured it was a allocation problem so i installed setup 1.x which can allocate 512mb to the card but when i try to chainload it after that it just gives me a black screen and when i turn off the GPU at the black screen i get a BSOD. What can be done? Oh and my USB port stopped working and i dont get what the pci.bat explanation thing is in the troubleshooting. Any help at all would be appreciated! Thanks

You may try these steps to prevent BSOD, it works for me:

I had to take the following steps to get the drivers installed and running stable. I don't know why, but the driver goes crazy (read: BSODs within minutes of booting) if you don't install it with this method.

1. Boot to windows normally with the eGPU plugged in (do NOT run compaction and chainload)

2. Let the standard VGA driver install

3. Restart the machine

4. Again, boot do windows normally. Do NOT chainload.

5. Install the 275.33 drivers

6. Restart the machine. Once again, do NOT chainload.

7. You will see an error code 12 for the GTX 460 in device manager. Now let's do the egpu setup stuff, restart the machine.

8. Break the reboot into egpu setup. Load the eGPU video card, run compaction, set the chainloader to win7. Chainload win7.

9. Everything should work now. With video directed to an external monitor you can remove the expresscard and the video signal correctly drops back to the notebook screen. You must restart the machine and chainload to re-enable the eGPU though - I found that plugging it back in, with or without the sleep trick, did not re-activate the driver.

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.

To get pci-e 2.0 speed use Setup 1.1x's PCIe ports->Link speed.G2. You'll know if Optimus pci-e compression is enabled if your 3dmark06 score is > 10k. If it's < 10k then pci-e compression isn't enabled. It should be enabled as your E420 has an primary bootup iGPU as the video device.

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

The compaction solves the error12 issue, but you are using a PE4H 2.4 and your system's expresscard slot would default to Gen2 (pci-e 2.0) speed. The PE4H can only reliably run at Gen1 (pci-e 1.x) speed, resulting in the systems that you describe.

So you either need to set the expresscard slot to run at Gen1 speed in the bios, is such a setting exists, or use the DIY eGPU Setup 1.1x's PCIe ports->Link speed.G1 option on the expresscard slot to force Gen1 speed. The better option would be to offload the PE4H for a PE4L 2.1b that can run at Gen2 speed.

can anyone send me DIYeGPU-Setup-110b5 because i'm in egypt and can't purchase it

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.

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.
