eGPU experiences [version 2.0]

[mmikeman]

Got a laptop egpu setup with an acer aspire 5755 (i5 2.4ghz sandy bridge cpu w/intel hd3000 onboard) , linked to an ati 5770 radeon 1gb card + PE4H v2.4a + PM3N, at first tried everything to get this working, chainloading the egpu w/windows no ddst resulted in error 12, did the ddst overide and loaded with windows, still error 12, tried the alternate ati drivers listed on a forum, those didn't do anything before or after the ddst overide, finally purchased setup 1.x, had to mess around with it a lot but had success, error 12 was clear however the egpu didn't work still, it seemed the card was working properly in device manager but the ati driver interface wasn't showing a lot of options and trying to disable the conflicting intel hd3000 would result in a bsod (the bsod would say something about ati.dll), finally messed around some more, got the egpu functional by using setup 1.x to recondition the link speed to gen 1.1 (2.5T) then pci compact the egpu (56.25g 36bit) and forcing the igpu to 32bit, card started up finally for the first time had all options in the catalyst control center, other monitor came on properly, no blue screens however very poor performance due to the 2.5T speed, tried everything including playing with the delay switches on the PE4H v2.4a + PM3N to set this egpu to gen2 speed (5T) but for some reason no luck, it seems at gen 2 speed the device seems to work properly with no errors in windows however doesn't function period, could this be a compat issue with the HM65 chipset my laptop has or anyone have any ideas to get this working faster? Tried some performance tweaks as well and even overclock the gpu with no luck , any suggestions?

Your Series-6 mPCIe slot can run a Gen2 link however you need a PE4L-PMxxxA 2.1b to do that reliably. A PE4H 2.4 has a socketted cable that unfortunately does not hold a Gen2 link properly. See my testing at http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-132.html#post55765 that shows even the newer superior PCIEMM-060B cable still can't negotiate a Gen2 link.

BPlus have been advised of this yet are still advertising the PE4H 2.4 as Gen1+Gen2, but are now putting a disclaimer on their PE4H 2.4 page: Notice: We can’t guarantee it work PCIe Gen 2 speed with your laptop. Depends on signals quality and platform condition.

I'd suggest you contact them to replace the PE4H 2.4 with the PE4L 2.1b AND advise them to cease misadvertising the PE4H 2.4 adapter as Gen2 capable. There is not 1 documented case of it being able to hold a Gen2 link.

EDIT: I've emailed BPlus requesting they cease advertising the PE4H 2.4A and PE4L 1.5b as being Gen2 capable here.

You can also refer to this thread to see that it is highly desirable to have a socketted mPCIe solution (at least on one end), which unfortunately BPlus have not as yet provided: http://forum.techinferno.com/diy-e-gpu-projects/2958-pe4l-pm060a-mini-pcie-extender.html#post40824

Hey,

I've received my PE4L-PM3N 2.1b and wanted to install Setup 1.2, so I started setup-disk-image.bat and everything worked until the point of creating the devcon.txt.

It creates the file but I get the message "BIG WARNING!! mkdevcon: PCI BUS section NOT found".

So, as it is told below that message I opened the devcon.txt and searched for the section but only found the PCI Express Root Complex which seems to be normal for newer devices.

I deleted the part and started Setup 1.2 via USB stick and chose the second option: "menu-based".

At the following process I then get the error message " 'compact' crashdumped so cannot do PCI Compaction on this system." which shouldn't happen as far as I understand.

Am I doing something wrong?

I use the Asus N550JV with Windows 8 x64 and a HDD with GPT(therefore the USB stick).

The devcon.txt looks like the following(it's German, the deleted part is the one named "Stammkomplex für PCI-Express"):

I also switched to English language causing mkdevcon to find the PCI Express Root Complex but it didn't delete anything there, the lines were still the same.

I haven't plugged in a graphics card yet because I wanted to have this stuff running first and this shouldn't be problem, should it?

Thanks for any help.

On a very few systems compact.exe crashdumps as you see. The PCI compaction menu will be disabled. Loading from disk image may help but that would need a MBR installation. You have TOLUD=3.24GB.

At this point it's not so important. Your critical step is seeing if you can disable the GT750M and chainload out to Win8-UEFI with Clover and/or Tianocore UEFI-DUET where *it maintains* the PCI config space. If not then will need to consider either loading Clover (or grub2-EFI) onto your system and trying the dGPU disabling via it's commandline OR converting to MBR and using Setup 1.x' 'chainload mbr'.

I'd also fish around in the bios to see if you can disable the GT750M there too.

Your Haswell i7-quad Asus N550JV configuration is one of the more advanced ones (mPCIe, UEFI, iGPU+ NVidia dGPU) that would promise high performance if get it all sorted. Pls contact me offline if you need more assistance.

I have a T430s, a PE4L and a GTX 460 (planning to upgrade sometime in the future). What software and settings do I need to make it run with optimus on the internal screen? How do I check if 1.2 opt is enabled?

[EpicBlob]

Hey guys, I have a 4530s with a 2670qm cpu with intel hd 3000 and an expresscard 2.0 slot. I plugged in a 560 and everything works great but my link speed is stuck at 1.1opt instead of 1.2. Any ideas on forcing the full link speed?

[back4good]

Hi everyone! I have a Vidock 4 Plus Overdrive with Quadro 4000. The setup works fine on my Thinkpad X220 (i7 2nd gen, Win 8 Pro 64, 4GB x2 ram, HDD) without any modification. However, when I try the same setup on Thinkpad X230t (i5 3rd gen, Win 8.1 Pro 64, 4GB x 2 ram, msata SSD), it gives me error code 12. Using just 2GB ram works for X230t, but is there sure way that I can use my whole 8GB ram with the setup? I'd really appreciate your inputs!

Do you have PE4L, if you do then check in bios that your expresscard speed is set to 2.0. Then, did you halt Win with F8 then connected expresscard and booted to win?

Also check link speed when gaming or other intensive GPU activity.

T20 may have PCIe SSD, such as SanDisk A110 PCIe SSD;

In this case, PCIe X16 graphic card might be replaced from PCIe SSD by using M.2 / NGFF to PCIe adapter.

Hi all,

I too am preparing my own eGPU setup as follows:

[GTX 680 2GB] + [PE4L] + [sonnet Echo] + [TB cable] + [250W PSU] + [DIY eGPU1.2] + MBA 2012 model

My Doubts:

1. Instead of PE4L V2.1 ( PCIe Adapter ) if I purchase PE4H (PCIe passive adapter ver2.4) will it give performance boost? Since former one uses 1x whereas later uses 16x (my theoratical understanding - that later will have faster bus speed). Also, is PE4H V3.2 (PCIe x1 Adapter) is benificial only for having an enclosure or any other advantage?

Just for my understanding - the graphics card motherboard connection has huge (x16) length than the PCIe adapter (which covers only 1/16th or less/more of it). So that does effect the bus/other speed, right? How much will the graphics card underperform?

2. Sonnet Echo will converts 10GBps TB link to 5GBps ExpressCard. An expensive $320 Sonnet Echo Express SE is available with 10GBps speed. But, as cleared by Tech Inferno Fan earlier, it has issues (an underpowered power supply, no PCI Delay switch, etc). So, are there any other alternatives for the same? If not, then isSonnet Echo enough to give good fps?

Once my doubts are cleared, I will start with my setup and will surely post the experience on the way and results/best practices!

Thanks in advance

e-gpu stands for External Graphics Processing Unit (your graphics card). This is connecting a desktop class GPU to your laptop, small form factor pc, or any type of computer that has the GPU out of the box. The big reason for this is physically, a desktop graphics card isn't able to fit within a laptop. The graphics cards inside laptops also aren't comparable to a desktop card. But the CPU of a desktop and laptop aren't too(too) far apart so it is mostly the GPU that limits the computer.

The main point is to give laptops/other systems desktop-class power. This is great for games, video editing, 3D modeling, or pretty much anything that requires horsepower.

[Tech Inferno Fan]

hi, i'm new in this forum, can someone explain the basic functions of e-gpu, is it somewhat equivalent to vidock?

PE4L 2.1 or PE4H 3.2 are functionally equivalent to a ViDock. The difference is you pay quite a bit more for a ViDock but get considerably less. DIY eGPU is considerably cheaper, can use DC or ATX input power, has mPCIe solutions, better documentation and support tools along with a larger support community. The shortcomings with ViDock when compared to DIY eGPU can be seen by the RED items in the following comparison chart:

1. PE4L 2.1b or PE4H 3.2 are the only ones that support Gen2 (5Gbps) links. Older PE4H 2.4 does not and should be avoided for your implementation. All of these products would be using only the first lane (x1) regardless of whether the physical slot is x1 or x16 in size. In your case it would be a x1 2.0 link.

2. If you are prepared to mod the Sonnet Echo Express SE or OWC Helios, then it's a better solution than the PE4L+Sonnet Expresscard Pro as you'd be getting slightly more than double the bandwidth for less than $100 more expense. If you have a 15" MBP/MBPr then this is the recommended solution for high performance as x1.2Opt (Optimus) x1 pci-e compression is somewhat difficult to engage due to a non-functional Intel iGPU on those systems.

Update:

Got the PE4L 2.1 (expresscard) + SWEX. Immediately tried hot-plugging, worked flawlessly.

3DMark 06: ATI Radeon HD 4870 video card benchmark result - Intel Core 2 Duo Processor P8600,LENOVO 2767W2E

Now I guess I need the setup 1.x to get the x1e and... oh s#@$ can't PM yet. All in due time I guess

Let me know what other details I should post so that the info may be added to the performance/compatibility/etc table.

Thanks!

I have already purchased [PE4L] + [sonnet Echo] and have 2012 MBA (not MBP).

Is that going to be an issue with regards to bandwidth?

[Dmitry]

Sorry that is not on. I do not speak English. advised this site, but where's the look I do not know. The question is: MSI U120-015 + eGPU, possible or not. There is a built-in 1GB memory and integrated GMA950 video. There are two free plug mPCI.

Please otvette a question or tell me where exactly is the answer. Thank you.

Aug-2013: Setup 1.20 beta now being distributed with many new features: Series-7/8 chipset, Win8, polled eGPU detection, Macbook installation, 13" Macbook PCI compaction, 36/64-bit compaction matching DSDT override + more. Will be officially released once HIT's involvement is finalized.

@Tech Inferno Fan: Is the Setup 1.20 already final and is there also a changelog available? I would be interested which "+more" features are included.

[angerthosenear]

It's that time of year again, eGPU issues...

I cannot update my driver at all. It fails during install (after the screen start flickering when it tries to install the new one).

I'm currently trying to install the 327.23 driver (I'm currently on 314.22).

I don't dare uninstall my current driver, that's a few hours of work in hopes of getting it reinstalled.

Is there something I'm missing that I can't install any driver updates?

--

I noticed the Intel HD Graphics 3000 is shown as the main GPU, is this due to compaction and whatnot? Would this be why driver updates are error'ing, since the nvidia drivers sees the nvidia eGPU but tries to install over the intel ones?

[Lwerewolf]

Think I just hit a dead end with my current setup here.

Port 4 is the expresscard, port 3 is most likely the 3G/GPS device (i.e. modem), port 2 is wifi, port 1 and 5 are free (those are the dock's PCI-E plus... something else, dunno what).

Is there a way to do the x1e tweak on an even port, if the adjacent odd ports are free?

T400 schmatic snippet in the spoiler shows:

port1=WWAN (minicard)

port2=WIFI (minicard)

port3=WUSB (microcard - assuming is a half-sized mPCIe slot)

port4=expresscard

port5=DOCK

port6=LAN

So you only have mPCIe port1 (WWAN) or port3 (WUSB) that could provide a x1E link or even x2 link. However running either that way would see the port2 (wifi) no longer usable since port1/3 would be running in x2 mode. You'd also need the PM3N end on your PE4L to do that.

Rather than mess with this I'd suggest getting a NVidia GTS450 or newer video card. If your T400 has an iGPU then you'd get x1.Opt performance where x1 pci-e compression is applied along with an internal LCD mode. It would perform considerably better than your HD4870 using just a single cable expresscard solution.

@Tech Inferno Fan: Is the Setup 1.20 already final and is there also a changelog available? I would be interested which "+more" features are included.

Still beta until have finalized HIT involvement. That's turning out to be a long drawn out process.

Had this problem 2 weeks ago!

Nvidia seems to f-ed up with their drivers.

I re-installed my drivers in safe mode, tell if it works for you!

atm I'm trying to install the 327.23 driver (since it is the latest WHQL driver), which driver version are you able to run stably? With 327.23 I get error 43 on my eGPU, even though the driver apparently installed successfully.

Huzzah! I got it finally, I'll post more in my guide thing here (seeing it is iGPU+dGPU+eGPU) issue probably::

It's not recommended to deal with HIT for reasons as outlined in http://forum.techinferno.com/diy-e-gpu-projects/3793-summary-dealing-hits-abandoned-egpu-commitments-%5Bcustomer-thread%5D.html#post53541 . From Feb-2012 to June-2013 Randy @ HIT was given permission to bundle Setup 1.1x with his hardware as incentive to generate business for him. He was also given permission to collect donations for standalone supply of the software, donations that were advertised for "eGPU development purposes".

Unfortunately Randy is unwilling to provide those donations which instead appear to be funding his food stash as seen at http://www.facebook.com/randy.case . Subsequently permission to distribute Setup 1.1x as been revoked. If he is still trading and does supply it to users then please report the illegal practice here. His PE4L 2.1b page says "Out of Stock until 10-03-2013". If so then he's being sheparded along by the old NBR DIY eGPU experiences thread that's still advertising his goods. NBR have refused to remove that content, something which they've been using to obtain advertising revenue from. Both US companies trading in unlawfully obtained intellectual property.

Details of the correct way of acquiring the newer and substantially better Setup 1.20 are on the first page of this thread http://forum.techinferno.com/diy-e-gpu-projects/2123-diy-egpu-setup-1-x.html#post27337 . Yes, it is a $25 restricted donationware directed for "eGPU development purposes".

Thanks, I will purchasing once all my H/W comes.

Also, since I have a 2012 MBA (with Intel HD 4000 iGPU) and will be using [GTX 680 2GB] + [PE4L] + [sonnet Echo] ... will I get "x1.2Opt (Optimus) x1 pci-e compression" (something which I've read in the forums for much better performance).

Do let me know if this is the wrong thread to ask this Q

Hello,

I have tried to get a Nvidia graphics card to run the internal LCD of my laptop with the most recent graphics drivers(327.23), both desktop and notebook editions of the driver. I am able to get the card to output to an external screen, but when I try to run it back to the internal LCD, it uses the on board graphics instead of the eGPU. I have tried it with a GT630 and a GTX550ti, and have a Lenovo X200. My procedure is to install the drivers, then restart with the PERST delay on the PE4H set to 6.9 Seconds. The Windows 7 boot sequence either hangs, goes black, and once even BSOD, although I did not catch the error message. I was able to install the notebook drivers by editing nvamn.inf allowing the card to use section 099 like in the old kizwan edits of 295.73. Am I doing something wrong?

Thanks in advance

EDIT: I have also tried to hotplug from standby, but no luck there either
