PE4H 2.4b can only run a Gen1 link. You need a PE4L 2.1b to run Gen2. To confirm that Optimus' x1 pci-e compression is engaged, run 3dmark06 on your eGPU. If the result is > 10k then yes, it's engaged. If it's < 10k then it's not engaging, something that shouldn't be the case if the iGPU is active.

Getting 20322 score in 3DMark06 yet still Battlefield 4 and DayZ play pretty lagged out, even in campaign...

I've had a user report privately that a Win8.1 + 15" MBP + Echo Express III-D + NVidia card works completely plug and play in UEFI (not bootcamp) mode. No guide has been forthcoming as yet, though wish we had one.

Within Setup 1.x, run Save Diags->compact fails, upload the results to mediafire.com and post the link here.

Obtain Setup 1.x to troubleshoot the mPCIe connected further if you have had no luck doing the OS-halting method to overcome whitelisting.

If your monitor configuration is such you in fact just running the accelerated internal LCD to an external display via the VGA port then yes, performance would be affected. You want the eGPU to display straight out to a monitor.

Other ways to improve performance would be

1. Get a x1.2Opt capable PE4L 2.1b-> double your bandwidth

2. Disablie NVidia sound would ensure the bandwidth is dedicated to video traffic only.

3. Putting a FPS limit via the NVidia drivers (or ASUS GPU Tweak / MSI Afterburner)

4. Try to lower resolution and lower color depth from 32-bit to 16 bit.

Hey nando really appreciate your continued support on this topic. So I have a PE4H 2.4b, so I think I should be able to support a 1.2 link? But every time I use your program and try to do a Gen 2 setup it simply doesn't display anything out of the DVI-D. And also, I do have the card directly displaying to the monitor, however what I'm saying is for some reason it wont display unless my laptop is also connected to it via its VGA port...very strange

UPDATE: I'm able to get it to work without the VGA now. Now my only problem is getting it to work when I select Gen 2....ALSO, I just did a test with GPUZ and while im playing there is no load on the integrated GPU...meaning Opt is not activated....Im using regular drivers do I need to use the modded ones?

UPDATE: I turned on vsync and it helped a little...

Would really appreciate it if someone could help me out. My GTX 560 ti is working with a 1.1Opt link on my Lenovo X230 however any game I play on regaurdless of settings will have this stutter in frame rates. I have downloaded the newest drivers for everything and was wondering if anyone had any ideas where to start on how to fix this. Thank you!

Also interesting troubleshoot: Both my integrated laptop monitor and external work when my VGA is connected from my laptop to my external. I also have my DVI-D cord from my eGPU plugged into the external. The monitor is running off the DVI-D, however my external monitor will only work if the VGA from my laptop is plugged into it....might be part of the problem

So I guess it's normal that my gtx 560 is only running at 1.1Opt but there are still jitters in fps when I play. I tried updating every driver I have with no luck... Any ideas?

I'm having a little issue with my eGPU setup and was hoping you could help. I can get my eGPU (Nvidia 560 ti) to work on my Lenovo X230T. The problem is it runs at x1.1 instead of 1.2, and I'm not sure if that's the reason that everything I play, regardless of settings, has somewhat of a stutter every now and again. It will play at high fps but will stutter a lot. Any ideas?

Sent the money, please let me know when you got it and sent the link. Thanks.

And now its back to how it was, where it is only showing on my internal LCD....

I am using a PE4H and a GTX 560 ti with a Lenovo x230. I connected it, it saw the device as the standard VGA, I installed drivers and it now shows up as a GTX 560 ti. No matter what I do (uninstall its driver, uninstall both it and my intel HD 4000 multiple times) I cant get anything to show up on my external monitor...Anyone have any ideas?

UPDATE: Now I got it to work on my external but not my internal...

I think this one would be a good one to get, very cool running, and probably only just a little overpowered for your CPU, but not by much I don't think:

ASUS GeForce GTX 760 DirectCU II OC

ASUS GTX760-DC2OC-2GD5 GeForce Direct CU II OC PCI-Express x16 2Gb GDDR5 graphics card - 90YV04L2-M0NA00 - (Components Video Graphics Cards): Amazon.co.uk: Computers & Accessories

Here's a review:

ASUS GeForce GTX 760 DirectCU II OC review - DX11: Futuremark 3DMark 11 & 2013

Very cool running, doesn't use huge amounts of power, overclocks well, and it's the latest generation of tech.

Really depends on how much you want to spend, but with that CPU of yours I wouldn't get anything that is faster.

(Don't really know anything about external video cards, so you will have to work out if it's suitable for you from that particular point of view).

EDIT: I was interested in this whole eGPU thing, so read up about it now and came across this thread, I'm sure you've seen it before but I'm including it here in case you haven't (might be useful):

Yeah that one is a little out of my price range. Max im trying to spend is 170 on the card. Thanks for the links though and the advice!

Your CPU may prove to be the bottleneck in some more modern titles that can use 4 or more cores, like Crysis 3 for example. However, your hyper threading helps a lot on that dual core, and it's got a high clock speed. Also, the GTX 480 is not a particularly powerful card anymore, about 5500 3DMark11 score, so that's not going to push the CPU that much. Also, I don't know how much of a hamper the external connection of the GTX 480 is going to put on the performance of the 480, that might lower the 480's performance even more thereby further reducing any possible CPU bottlenecks. Either way, the CPU and GPU are both not very future proof, or in fact even current proof, but I guess it's a good upgrade if you can do it for cheap. Yep, so I wouldn't bother upgrading your CPU, it wouldn't be worth the money.

Hey thanks a lot for the reply. One more question if you have the time. Would you know what graphics card I should get if I wanted to match the limits of my CPU? If I use a NVIDIA card I can have a 1.2opt link so it shouldn't hamper my card that much as an external card.

I currently have a Intel Core i7-3520M 2-Core 2.9GHz. I was about to buy a GTX 480 (and use it as an external GPU), but then I thought that this processor might bottleneck my card. Can anyone confirm or deny this?<!-- google_ad_section_end -->

Can someone confirm or deny this statement I found?

"The latest X230 bios per X230 expresscard adressing (eGPU) - Page 3 - Lenovo Community does change TOLUD to allow an eGPU to be accomodated in 32-bit pci-e address space *if* it detects an eGPU during bios bootup. Meaning you must have powered on the eGPU and have it attached to the X230T before powering on the X230T. Ensure too the PCI Reset Delay jumper (SW1) is set to position 1 (0 seconds) so it doesn't add any detection delay."

If this is true, it will only be dfa00000 until I plug in the new eGPU in.

I decided to look around to make sure my computer was even able to run an external GPU and found I have hit a wall. I flashed my BIOS to the newest version (like 2.67 or something?) but my TOLUD is 3.5 GB (dfa00000). I thought the BIOS update was supposed to fix this? I only have 8GB of RAM so the 16GB problem shouldn't affect me either? Anyone know what might be wrong?

When reading some forums I saw that people who updated their BIOS were able to fix their problem as long as they only had 8 gigs of ram, which is why im confused I still have DFA00000.
