Tech Inferno Fan Posted October 1, 2014 Author Share Posted October 1, 2014 Yes, its working. I already added the steps in my Guide (maybe you can add it to the headline).I sold my R9 290X (wasnt able to play WoW with low settings, but its a WoW problem) and also sold my 780Ti OC version from Gainward (some strange noise when gaming). At the moment im using a 780Ti from EVGA (no OC or anything). The problem with the Benchmarks is Windows 8.1. With my PE4L i was always getting lower scores (W8.1), but i will try Firestrike later and report.Thank you for the update. Changing the headline is easy. What's more important is your is the first and only Thunderbolt Lenovo implementation we have: http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#ThunderboltIt would then help tremendously for anybody else wanting to acquire a W540 and leverage off your pioneering work if you could change your thread to focus on The Thunderbolt side. That is, what hardware you used and the steps to get it working. The PE4L could be perhaps added as an appendix? While Win8.1 benchmarks might be lower I'll happily add whatever you are willing to share to the Leaderboard. Link to comment Share on other sites More sharing options...
Videoapan Posted October 1, 2014 Share Posted October 1, 2014 Yes, Setup 1.30 willl help deal any mPCIe slot whitelisting as well as disable your NVidia dGPU. The latter necessary to activate x1 pci-e compression and internal LCD mode using the eGPU rather than dGPU.Hi!I recently set up my old ASUS F3Sr laptop with a Nvidia GTX 460 through a PCIe-adapter and it works relatively well with an external monitor. What I would like though is for it to work with the internal screen if possible. The laptop has an integrated ATI HD2400 which makes me wonder whether or not it will work with Setup 1.x. Do you have any experience with a setup like that? There is no internal intel gpu, only ATI.Oh, I also had to remove 2 GB of RAM, I'm guessing that I will have to live with the lower amount even with a working Setup 1.x?Thanks in advance!

thomas_price1 Posted October 1, 2014 Share Posted October 1, 2014 If we compare GPU scores to my TB1 @10Mbps, 'regular' clocked Zotac GTX 970:Core clock 1,076 MHz vs 1,314 MHz Memory bus clock 1,753 MHz vs 1,853 MHz (You totally kick my ass)3Dmark06:ResultTotal of 24% higher3Dmark Vant:Result21% higher GPU score3Dmark11:Result35% higher GPU score Fire Strike (11472 vs. 8872)29% higher GPU scoreEDIT: Is it possible that you can make a power measurement during Fire Strike to see how much power your card peaks?No sorry, I was planning to buy a wattmeter but since my egpu is stable it's not a priority anymore.If that can help you I tried 3dmark11 with your GPU's clock : http://www.3dmark.com/3dm11/8781851 2 Link to comment Share on other sites More sharing options...
davide445 Posted October 2, 2014 Share Posted October 2, 2014 .......I am too much busy testing my rig, recently my system is now having the sleep bug issue, I did a little research and I found that this issue is sporadic with old AMD cards such as the Radeon HD 7XXX series. What happens is that once your CPU and GPU is under load (apps games) suddenly monitor goes black but both Laptop and eGPU is on and working but nothing is being displayed on the monitor as if in "Sleep Mode" and there is no choice but to hold power button and reboot system, tonight I will by trying it the newly released AMD Catalyst 14.9 WHQL drivers and see if the issue is still present.I experienced also a stability issue: after few minutes of work (testing on video editing app and game editors) the screen go black and next return and the system state "AMD display driver stopped working and has recovered". I need to disable external display and reboot the system, otherwise I'm not able to do anything more.This is also your problem? Link to comment Share on other sites More sharing options...

I need to disable external display and reboot the system, otherwise I'm not able to do anything more.This is also your problem?The instability is because of either:- a GPU that's clocked beyond what it can handle -> use MSI Afterburner to downclock the GPU.- the eGPU hardware is incapable of running at Gen2 speed -> set your EC/mPCIe to Gen1 using your bios or Setup 1.30 and/or consider getting another eGPU adapter. NOTE: there have been a few video cards that just do not want to run at Gen2 reliability but swapping to another vendor's card of same type does. Impedance issue?- the PSU is incapable of supplying peak load power -> test another PSU. 2 Link to comment Share on other sites More sharing options...

I need to disable external display and reboot the system, otherwise I'm not able to do anything more.This is also your problem?I did not see any prompts that driver stopped working, it really turns off by itself (video signal lost but GPU is powered on) like last night I was playing Campaign style BF4 all of a sudden the cutscene stopped and video signal went out like the whole setup went to sleep. I Guess it can be a CPU throttle issue (for me) and or GPU hardware issue. Other guys told to plug and unplug DVI cable /HDMI to like remind the GPU it has a job to do and wake up from sleep and I did not try this yet. Some say win + P or ctrl alt del but sadly I have to long press power button just to restart which can be bad for the HDDSent from my SM-N9005 using Tapatalk Link to comment Share on other sites More sharing options...

Also PE4C V2.0 need to support Gen2 (right?). Will check if setting to Gen1 will solve the issue but I will be really disappointed since will mean much worse performance. 1 Link to comment Share on other sites More sharing options...

Also PE4C V2.0 need to support Gen2 (right?). Will check if setting to Gen1 will solve the issue but I will be really disappointed since will mean much worse performance.it can be that our laptops could not handle the bandwidth of the GPU activity..I experienced too last night when I overclocked via overdrive I set Memory at 1575 MHz, +20% power, and Clock Speed @ 1150, it really went off!(EGPU turned off! Power was cut and adapter did not have any light even the blue lights in the EXP GDC power port was off!!)AMD Radeon HD 7950 Boost is really such a hungry card I guess,Returned to stock settings and played BF4 Campaign and it was again that stable.It is really such an annoying occurence which is intermittent and so random.TLDR; my Lenovo G500 Throttles and Radeon HD 7950 is power hungryNeed to repaste CPU and GPU as well as effective cooling. @Tech Inferno Fanwhen I open GPU-z it shows that gpu is running at"PCIE 3.0 @x16 X1 2.0/2" Am I running at an ideal speed?

dan Posted October 2, 2014 Share Posted October 2, 2014 I am testing the Windows 10 technical prewiev and I guess that I find something useful to a egpu setup.if you just disable the pci-e port where dgpu is locate ,you can activate optimus because the dgpu simply desseapear from display devices list,unlike windows 7 where it was need to use x1.setup in order to do that.if you do that in windows 7 since I remember the dgpu stays in display devices list like a generic display adapter and optimus can"t engage.i have an intel cougar point HM65 second generacion based system.someone can confirm?or I am just missing something......it could be useful in systems where x1.setup can"t disable dgpu.i enable optimus this time without x1.setup.by the way ,this new system is not bad at allOK.No innovation here.after installing w7 i see that i was wrong.in w7 i can do the same thing with the same results.So nevermind.the only positive aspect for me is that i discover that my tolud is dynamic and no need for compactation and since i could disable the dgpu from de device manager i can pass from using x1.setup at all.anyway is a valious piece of software.

dan Posted October 2, 2014 Share Posted October 2, 2014 I am using x1.setup and its very helpful in most of the case it is the only salvation.i install it in this new system and it works great.from my experience in windows 7 the only way to achieve optimus performance is by using x1.setup in order to disable dgpu.it is not working with just disable it whitin devicemanager. good luck with your egpu setup tomororow!

useafo Posted October 2, 2014 Share Posted October 2, 2014 unfortunately, I can't make Gen2 link work, after such a long 2 weeks. Thus, I confirm that EVGA GTX 660 won't run at x1.2Opt.

Thanks man! Yea i also been trying to find out too to determine which port is what. Its so confusing this is just an assumption but look up how to find how big your tolud size is and usually the first one that is A00000 or something like that should be your first port and so on, by the way that was just an example, yours might be different. From the detail, i think you can look up what port is using what. Sorry i cant remember exactly on how find your tolud size Link to comment Share on other sites More sharing options...

I'll try to buy the same card, but from another vendor.sorry for that,unexpected I am able to run x1.2 link with an pe4h v.24 in a hm65 chipset,gtx 750 ti ghraphics card.it is connected to mpci-e slot.try reducing pcie traffic by disabling pcie devices,and if you have pci latency timer option in bios work with it.or use a tool to assign latency on each device .aparrently pci-e links does not need for that but you can try it.my msi ge620dx has that option and by increasing the latency games run much smoother and the frames are more steady.

davide445 Posted October 2, 2014 Share Posted October 2, 2014 Crossing my fingers maybe I did find the problem.First I did apply this fix "Display driver stopped responding and has recovered" error in Windows 7 or Windows Vista and second looking at Catalyst Control Center Performance settings appear that OC was still enabled for some reason.Returned settings to default one and I'm working without any problem since one hour.Last remaining problem to be addressed the screen flickering, but since now I'm able to work on DaVinci Resolve 11 and Unreal Engine 4 Editor without any problem, something impossible using iGPU.Magic eGPU!

braised_beef Posted October 3, 2014 Share Posted October 3, 2014 my experience was exactly the same (using PE4C) and the solution was in the sequence: need to wait the laptop was up and running and only after connect the (already powered) eGPU.The laptop then recognized a new device, search and install drivers. After that you can install vendor specific drivers for your GPU, and in my case was asked for reboot. If you have already installed vendor drivers uninstall it and wait the system has installed his drivers. If all is ok next time you need to boot always with eGPU already connected and powered. Also pay attention to make your external display as primary if you want benchmark and app can experience the new hw acceleration. Hope this help and your case is similar to mine. thanks buddy, everything works except i cant output to my monitor o.O in the device manager it list my card as gtx 650, thats good but theres an exclamation next to it... what does it mean?
