eGPU experiences [version 2.0]

[Tech Inferno Fan 20]

Wow thanks for such a quick and in-depth response. Yes - I was aware of the issues - I just figured as long as I followed that guide I'd be okay (I really like this notebook for my work and the card is such a good deal). I also saw that others have gotten it to work.

If you read further down - eddynator had originally run it with 2 gb but had successfully switched to 4+2 at the end.

So basically in summary - my options are - install win8.. which is probably out of the question due to work.. fix the override errors (I've gotten them down to 149 - but I have no clue of why I'm getting so many - my current laptop has 28 for example and it's old/outdated etc).

How about win10 - will that allow me to disable igpu/work with your setup?

I also won't be using the internal for gaming - so it's fine if it's not accelerated. It will always be plugged into my 1080p viewsonic.

Okay - I will spend the weekend fiddling with the override - I've signed up for macforums to ask for some advice as they have a forum dedicated to it and this kind of stuff actually relaxes me (I shoulda been a coder I guess).

If that doesn't work.. is it possible to boot off a caddy hdd once I get a caddy in? I could install win8 into it and just hot swap (or leave it in) when I want to game. Or perhaps dual boot win7/win8 off same drive if needed (I've never looked into dual booting before but losing ssd would kinda suck).

In the mean time - I'm going to go see if the 2 gb memory option works - again thanks for the quick response. Maybe the other poster got this to work because he had win 7 enterprise and I have home.. or because I have ssd and he doesn't - I have no other changes to my system. Not really sure why it was so simple for him.

Yes, @eddynator got 6GB + eGPU with Win7 to work after successfully applying the DSDT override to create a large memory area and using Setup 1.30 to pre-allocate the eGPU into the large memory (56.25GB). See relevant quoted text below:

Windows 7 Enterprise 64 (A GREAT Victory!) (6gb, GTX 750ti sc, DSDT override, DIY eGPU Setup 1.30 software):

On May 24^th I learned the way the dsdt file works, export, modify, repair, compile, /loadtable. But windows was unable to assign resources to my eGPU (error 12), I will not get in more details here.

On May 25^th I got in touch with Nando, to ask about setup 1.3, I made a very happy 25$ donation and I got it the day after.

On May 26^th I got ready my 1.30 setup, pci compaction, and my eGPU got the resources needed from the long memory range. Now the SD card reader, seems not to work (error 12) but I don’t care, I usually use micro SD, and plug it into the computer with an USB adapter, so it doesn’t bother me.

First testing, I windows experience classification: 7.6! (on graphics and game graphics) up from 3.3. So let’s play. But before… I have got the 3D nvidia kit, screen, glasses… would it work?

Yes it worked, I made a handmade video, to not lose fps with some recording software, and well, I was so excited that I just grab my mobile and start recording.

[eddynator 15]

- my options are - install win8..

I must say that I never got it running under win8. But that was long time ago.

I had some bad experiences with Windows 8 and computers. When you install it, Windows 8 tries to install its own drivers. And you can afterwards install the latest drivers, but when you restart the PC it will come up with a black screen. What happened there? Windows didn't tell you must restart your computer to apply changes on drivers, and if you don't, and install e.g. last nvidia drivers, they will overlap the restart modifications. So you got that problem.

Something odd was happening with Windows 8 and my nvidia GPU.

But as I already told, that was long time ago.

Hi, sorry this part is kind of going over my head. I've been up for 24 hrs and 12 of those spent on this so that's part of it.. but in the quoted text he simply says he will not go into more details - I'm not sure what you mean by pre-allocate the eGPU into large memory (what memory? sorry again - not a pro at this stuff, learning as I read) - if so - can I do this with 8 gb or 4?

If I put in a 4 gb + 2, for some reason my main pc (current one), only sees 4 - haven't tried doing it with the HP because as edynator can attest.. the 2nd memory slot is a REAL pain in the arse to get to.

But hey on the plus side - I did have enough test before I have to go to take out the sticks and I'm up from 3.3 to 7.7 With 7.6 disk transfer rate and 6.5 processor score that's not bad!

Memory calculations though 5.5

I don't want to spam so I'll quickly respond to eddy - hey man - didn't know you were still around - I'm too new to PM but noticed you only had 2 posts and yet here you are Yes, I know you couldn't get win8 to work but I've read several posts where 2450p people did get win8 to work. I'll be happy to find links when I return if needed - but they never said how or I would've bookmarked them.

But do you mind pointing me in the direction of how you went about figuring out override issue? You said you have done a lot of reading - do you happen to know where/what? I'd be more than happy to do the same and post a guide after... do you think it has something to do with you having win7 enterprise and only 6 gigs of ram vs my 8? Any clue at all?

I mean brand new install and even though it's used, the laptop is a rock (I was waiting for a deal for ages and finally lucked into one), so what do all these errors mean - faulty hardware/poor combinations or? I couldn't figure out what the errors fundamentally mean during my research as I was tunnel visioned on simply finding ways to fix them.

Thanks for your guide - and I hope I can replicate your success without needing to mess with win8 (I have it on my other laptop and god I hate it.. and it just wouldn't work well for work). Okay I guess I'm gonna be late again.. have to teach my student something about confidence intervals and t scores... I don't know lol.

Hiya,

Thanks for your report - I have read quite a bit of successful ones with your setup but I guess I went with the wrong laptop - I'm really happy with it for work purposes but yeah =/

If I do most of the steps you mention, I get issues (usually just doesn't start). Maybe I'll just buy the x230 lol. That's part of the reason I love this setup - I can have backup laptops.. and it's flexible.. etc.

Hi,

I am reporting back with my 750Ti I mentioned about on post #4626

I ran into an error code 12 with my X230. However, I did find a way around it; although someone more experienced can tell me the underlying mechanisms.

If I plug in my egpu system with the external monitor attached to the gpu (1080p via VGA to DVI) prior to boot, I will not get past the bios password screen, where I just end up with a sustained black screen.

If I plug in the egpu setup after I have booted into windows, I get an error 12 in device manager.

Now, if I plug in the egpu setup without my monitor attached prior to boot, the entire system boots up and I get no errors in device manager (below is a screen shot of my memory allocation). Further, if I plug in the monitor at this point, I get video on the monitor (but not on the laptop).

Overall, I am unsure how this works and whether there are lost benefits. Furthermore, I am unsure if I have optimus working at all as I only installed Nvidia drivers for the 750 ti and not any optimus driver. Nevertheless, I am pleased I have gotten this far.

Thus, the following is my setup and benchmark results:

Lenovo Thinkpad X230 2306-CTOBIOS 2.62

2 x 8GB Corsair Vengeance 2133 ram

Smasung 840 EVO SSD

PE4L v 2.1 to expresscard adapter (set to 1 on both settings)

EVGA NVIDIA 750 Ti (non-superclocked) 2 GB (347.88 Nvidia Drivers)

EVGA Corsair 600w 80+ Bronze

Windows 7 64 bit

3DMark06 (1280x800; PhysX NOT set to CPU; no HDMI audio): 18862 (8 gb ram); 19177 (16 gb ram)

I also have a T430S so I ran the same setup as well. The same problem and workaround also occurred with the T430S.

Lenovo Thinkpad T430S 2353-9VU BIOS 2.62

2 x 8GB Corsair Vengeance 2133 ram

320 GB HDD

PE4L v 2.1 to expresscard adapter (set to 1 on both settings)

EVGA Nvidia 750 Ti (non superclocked) 2 GB (347.52 Nvidia Drivers)

EVGA Corsair 600w 80+ Bronze

Windows 8.1 Pro

3DMark06 (1280x800; PhysX set to CPU; no HDMI audio); 21359

3DMark Demo Firestrike 1.1 (1920 x 1080): 3649

Cinebench R15: 78.68 FPS

If anyone wants, I can upload pictures of my memory allocation during the two scenarios.

Cheers,

Louiek

edit/update

Hi again Nando - regarding what you said about needing windows 8 to disable igpu "Another method that could work is to use Win8.x and disable the iGPU. The idea there is to allow the eGPU to hijaak the iGPU config space"

I have managed to do this in windows 7, albeit with 2 gb of ram - it's kind of rough to do (sometimes it works some times it doesn't and I have to disable/enable/restart couple times). Would the setup help me in this instance or is it simply working due to only having 2 gb of ram? (the internal and external will not work together even on 2 gb). And I'm still receiving hundreds of dsdt errors.. still no luck finding a working explanation anywhere.

My next step is to try and setup win8 if all else fails and dual boot it. I'm downloading the trial right now. Will I need setup for win8 or did you mean I will simply be able to disable internal gpu with win8 and have this thing work with 8 gb of ram w/o the dsdt override needing to be fixed?

Speaking of Thinkpads.. I'm not sure if is relevant but the code I found on some other page had a fixed number for memory length - is this what you also meant and what I should try?:

QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,

0x0000000000000000, // Granularity

0x0000000C20000000, // Range Minimum, set it to 48.5GB

0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB

0x0000000000000000, // Translation Offset

0x00000001F0000000, // Length calculated by Range Max - Range Min.

,, , AddressRangeMemory, TypeStatic)

the 56.25 sounds familiar to what eddy seem to have been saying. I'm going to try that later tonight after jerry rigging a 2nd hdd into the hp (just don't feel like doing the entire restore/reinstall again (for some reason my restore points would not work).

edit: Oops I take that back - I can have both laptop IGPU and egpu going at once.. just never checked to extend. But I can still disable igpu from DM and it shows 'no resources allocated' to it. Hm. I wonder if there's some way I can do the same with more ram. Each time I tried this in the past I'd just get black screens on both.

[aaurnab 11]

Hi there , is there any video tutorial for DSDT override......

[arvazzz 10]

Hi guys, so recently i tried to join Laptop gaming as well buy buying EXP GDC dock. Installation worked well although i had to flash unlocked bios to disable Nvidia card which was in laptop. My setup is Acer V3-571G with i5-3230m, 6gigs of ram. EXP GDC and 350w PSU. For GPU i am using Nvidi GTX 750 OC edition from Gigabyte.

So i had installed driver and restarted computer and launched Tomb Raider to test the performance. It ran un Ultimate settings. Yay! AND THEN BAMS. Screen goes black and then normal again and it shows that Nvidia driver stopped responding, crashed and has recovered. I thought oh well, i red that it happens sometimes and carried on. Nope, after like 3-10 minutes it happened again, sometimes it happens even after 2 minutes. Sometimes after 15. What i've tried so far:

-manipulation with switches on EXP GDC. Didnt help.

-installation of older drivers. Didnt help

-using windows 8 instead of 7. Didnt help

-various settings in nvidia control panel. Didnt help.

So has anyone met this problem or i have a faulty EXP GDC adapter? I thought that may be my PSU could not handle GPU in games but i dont think thats the case because these crashes happen even when not playing games. Writing this it happened 3 times already. I noticed that CPU usage skyrockets when crash happens (MSI Afterburner). And no i didnt overclock the hard, i even tried to downclock it. Could PSU cause this? It's kinda old but i think it still should be enough for 750. If necessary i can provide PSU's stats.

I would appreciate any help as GTA V is gonna be release in the next few days.

Your eGPU adapter configuration isn't fully Gen2 compliant resulting in PCIe link retransmissions which eventually fail with the NVidia error you have.

Two solutions to consider: (1) can try other eGPU adapters like PE4L 2.1b with soldered ends giving better signal integrity (2) use Setup 1.30 with your existing eGPU adapter to downgrade your mPCIe link to Gen1 speed where you'll no longer : http://forum.techinferno.com/diy-e-gpu-projects/2123-diy-egpu-setup-1-30-a.html#post27337

@Tech Inferno Fan What exaclty do i have to downgrade? Could you explain more about dowgrading to Gen1 speed? I have some PCI related options in Bios. I am half broke student so i'd like to try everything as spending more money on this stuff is almost not an option.

I have options in bios to change PCI gen, would these work?

[ATTACH=CONFIG]14556[/ATTACH]

Those options change the Northbridge PCIe slot that hosts the dGPU to Gen1, Gen2 or Gen3. They have no effect on your expresscard slot attached to the Southbridge. Your options are then as outlined in my last post.

I installed win 8.1 and finally got my GTX 670 to work with just DSDT override!

I have got some reasonable benchmark results with considerable improvement over GT 650M but somehow the performance in game is actually worth...

Games that I have tried: Minecraft, Thief, Final Fantasy XIII. I haven't installed any other games in this new system, but I think its enough to show that I have the problem of eGPU giving worth performance than dGPU despite better benchmark scores.

System and games run stably with eGPU on Gen2. I can even switch between dGPU Optimus and eGPU Optimus by enable and disable corresponding PCI Express Root Ports without reboot.

I really have no ides why this happened. Could someone give me a hint?

(P.S. I am using the internal display, but I don't think that can explain GTX 670 performance worth then GT 650M in game, giving the better benchmark results. I don't have an external display with me right now, I can only test it with an external display when I get back to my place next month.)

Thanks in advance!

Your are sending internal LCD traffic back across that narrow x1 2.0 link, bogging down your performance. The solution is to get that external LCD you mention and test again. Can see an example of the performance difference b/w internal LCD versus external LCD performance at http://forum.techinferno.com/implementation-guides/2747-12-dell-e6230-hd7870-gtx660%40x4gbps-c-ec2-pe4l-2-1b-win7-%5BTech Inferno Fan%5D.html#post37197 . That was only at 1366x768. HD+ or FHD internal LCD mode will see a noticably bigger drop in performance yet again.

Here I am sharing about lenovo T420. in 2-3 days ago I updated to GTX 750 ti, I thought this card will be very power because it is up to so far. But my experience with this card is not good,ersion of

I tested many hours with several version6 of windows like win 8, 8.1 and win7... alltime 3dmark06 and 11 benchmark is 14000-15000 and 3999-4100, this is very awful, very frustrating because i was very nice result with GTX 560, it was about 2yr old card.

I tried setup 1.3 , but nando suggest me that it is not necessary for this PC because my TOLUD is 3.5 and as I never get error12, it is completely ok for eGPU setup. But he got some confussion about my large16GB memory, May be it is causes for performance deduction, Any way I am happy for getting workable eGPU setup but not enjoying stuttering in game like Fifa 15 and so....

I am switched to Win 8.1 with the suggestion of nando. that OS give me highest benchmark both 3dmark06 and 11 14620 and 4128...

Thanks for the quick response.

Have just ran 3Dmark11 X mode at 1080p in which GTX 670 is 3x GT 650M scores, but I guess I have to forget about benchmarks and get that external LCD to test in game.

BTW, for the best performance, do I just connect the external LCD to eGPU and switch to secondary display only in windows? I have already disable the High Definition Audio on GTX 670 in Device Manager, is there any other trick I can use when I get that external LCD?

It seems that we have a similar setup, and I hope you can help me. I have an ASUS Q501LA with a external GTX750 with a EXP GDC. I am trying to get the eGPU to use my internal display by enabling eGPU + iGPU. I can't do this because of TOLUD issues in which I have to do a DSDT override. I am not able to complete this process, so could you inform me how you were able to flash unlock your bios?

[Kaiyoti 10]

Where do you want to place the eGPU? Just naked outside of the M350? Without additional power and a riser you might be able to make a GTX 750 Ti work that doesn't need additional power.

I actually happen to have a 750 that I can try that with.

Some guy had unlocked it and uploaded in the internet with instructions. I don't know if that helps because i don't have Asus laptop and my problem is different.

Hi Nando,

I'm back with some updates and questions - if you recall I posted about asking whether setup 1.x would help me if I couldn't fix dsdt override - well the nice guys on the mac forum helped me out and dsdt override now compiles with 0 errors and my large memory is shown (I did not try the code I pasted here yet but went with the one in the original guide btw so in DM everything is as it is on others' screenshots).

That being said.. I ran into yet another strange problem and am wondering if setup 1.x is meant to address it. The problem is - if I have 2 gb of ram in the computer, no problem as before in terms of just booting up and at least getting the 750 TI recognized and working (only 1.1 bus - not sure what this means but I'll work on optimization later - I notice everyone is showing 2.0 - and I do have the 2.1b pe4l.. Anyway.

Soon as I stick 4 gb into the computer - shut down/start - (without eGPU being connected) BSOD when windows logo shows up (after about 2s or so as it used to do when I messed up my dsdt file - only this time, I simply take out the extra 2 gb and boot just fine).

So - is this what setup 1.x will fix or is this something else? I'm not seeing anything on google about it.

Thanks again as always.

[arvazzz 10]

@Tech Inferno Fan If you remember my problem... Are you 100% sure that your DIY setup would fix my problem? If it didn't help i would have spent money for nothing.

Guys, i have tried a lot of times. Laptop doesnt detect any gpu, actually egpu doesnt appear in device manager. HWinfo sees my r9 270x but there is no source for working ( there is no memory adress ) when i hot plug(on sleep mode), device detected sound is heard. after 1-2 sec device removed sound ! ( doesnt appear on device manager ) ((on my exp gdc light is red))

What should i do ?

How can i activate my egpu on laptop ?

I can't disable my gt540m. I dont know how to disable it, i dont know where are those settings too.

Please make suggestions. I have read many topics but i cant do this. It is waste of time because i couldn't find how to do this.

@Tech Inferno Fan If you remember my problem... Are you 100% sure that your DIY setup would fix my problem? If it didn't help i would have spent money for nothing.

Yes, Setup 1.30 can downgrade your mPCIe link to Gen1 to resolve your problem of an unreliable Gen2 link you describe at http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-467.html#post129275 .

The connect then almost immediate disconnect sound suggests some link level problem. If you have correct power to the GPU then I'd be inclined to say your EXP GDC Beast cable has some crosstalk causing this problem. I'd suggest getting a replace EXP GDC Beast.
