eGPU experiences [version 2.0]

Recommended Posts

Unfortunately the latest mac-mini specs list "Up to 3.0Ghz dual-core i7 processor". This being a slower CPU than previous gen mac-minis that packed a quad-core. This is highlighted in the article New, improved, slower Mac Mini | ZDNet . However, the 2014 version does have two 16Gbps-TB2 ports. Previous gens had 10Gbps-TB1.

We have some existing Mac Mini eGPU implementations. UEFI http://forum.techinferno.com/diy-e-gpu-projects/6578-implementations-hub-tb-ec-mpcie.html#Thunderbolt

Neither the 2012 nor the 2014 Mac Mini can give the optimum maximum 16Gbps-TB2 eGPU performance together with a quad-core CPU. Need to look at a 15" Macbook Pro or 15/17" HP ZBook 15/17 G2 for that (REF: http://forum.techinferno.com/diy-e-gpu-projects/4109-egpu-candidate-system-list.html#4th ) . Am hopeful the upcoming Broadwell release will see a larger selection of 16Gbps-TB2 equipped notebooks.

@Tech Inferno Fan

It seems that they really have listed it officially in this link;

https://www.apple.com/mac-mini/specs/

Two thunderbolt 2 ports sir Tech Inferno Fan, kindly look into it, I might buy it soon LOL!

Pesky hipster apple site does not want me to post image URL here hence I can't show any image

excuse me here it is out of DIY LOL;

Ah yes there is no quad core i7 Haswell only a dual core i7 that sounds like an i5 performer jeez...

Hi i have the same laptop as you (2540p) and i am thinking of buying the 750ti 2gb super clocked and the egpu kit, also a 220w dell power supply

I'm on windows 7 professional 64bit, i have 4gb ram.

My questions are

1) Where do i buy the setup 1.3 software

2) What do i do in the setup 1.3 software and when should i use it?

3) Should i just plug the egpu in my laptop when i first boot laptop then install drivers ? Or do i have to connect egpu after windows logs on

4) What is hotplugging

5) Will 220w be enough?

6)Is the express card suitable with my laptop? EXP GDC Laptop External External PCI E graphics card ARES Series Expresscard Set ATX-in Laptop Docking Stations from Electronics on Aliexpress.com | Alibaba Group

7)if you have spare time can you write a simple step by step guide on how to set it all up, it will be such a great help if you did so.

Sorry for alot of questions, the reason im asking many are because i am worried about the errors that will occur and if i am not able to solve them then my money will go to waste.

-Regards-

Hello, everyone! I want to make my choice what adapter to choose. I am prone to save money at the moment and to see whether the proposed adapters are feasible for my laptop. But if everything is ok, that would be good to have effective solution for eGPU.

My laptop is HP 530 with Intel Core Due 2.1 GHz CPU. It has mPCIe (probably gen2 and not just gen1) and slow PC card slot (133 MB/s). The PC card slot could in principle be used as a slow variant of expresscard after the corresponding adapter is bought.

I plan to buy a GPU like GTX 550-570 with possible further overclocking. So the power supply greater than 220W (as in PE4C v2.1 package) might be needed.

Is there any model where power supply could be added, not just somehow selected one, when more than one source is plugged in? From PE4C v2.1 description I find "Power Supply: ATX PSU, DC adapter, 8PIN connector (for D220P AC adapter),Three select one". The PE4C v1.2 is badly described. On its picture I see 4 pinholes near a switcher and 4-pin slot. Are not they for power supply? But it seems to be not a big problem if you have PSU with 6 and 8 pins, though its overall power should be high enough. And does not the cable from the adapter to the mPCIe plug require to solder it? :) There 3 cables in tha package and I don't see how do they stick into.

Also I want to use laptop's LCD, not a cumbersome external monitor. It seems that all models can grant this possibility. From http://forum.techinferno.com/enclosures-adapters/3100-pe4h-vs-pe4l.html I find "PE4L 2.1 and PE4H 3.2 have 1.2 Opt support". Is there an additional support for nVidia Optimus in the mentioned adapters and if so which one has the best support?

And about bandwidth. Gen1 mPCIe can pass 250 MB/s. Let's suppose we have 1280x800 32bit (I don't have larger) resolution with 25fps. Then we need 100 MB/s bandwidth if we want to transfer these uncompressed frames back to the laptop's LCD. Even if we have 1000 objects to render (game developers can give more realistic number) and to send them to the GPU, this seems to be a small percent of 100 MB/s. Then 250 MB/s seems to be enough for all the modern games and probably for the ones to appear in 5-10 years provided we use the mentioned resolution.

Taking the above mentioned into account I would buy the PE4C v1.2. It is the cheapest one and can allow up to 500 MB/s bandwidth for a larger resolution. And the cables from its package look certainly different than the PCIEMM-060A cable which is said to be for gen1 PCIe. For, say, PE4H both PCIEMM-060A and PCIEMM-060B cable are proposed but I could not find how to choose PCIEMM-060B.

HP 530 has only a PCIe 1.1 2.5Gbps mPCIe slot (2Gbps after overhead).

Best value eGPU adapter is a Gen2-capable US$50 EXP GDC V6 from banggood http://forum.techinferno.com/enclosures-adapters/6643-exp-gdc-v6-v7-discussion.html#post88642

Your platform has Optimus driver support ending as of NVidia driver 306.97WHQL (~GTX680 max): http://forum.techinferno.com/diy-e-gpu-projects/6253-t500-compat-q-4500mhd-optimus-ends-306-97whql-3.html#post89243 . You may consider getting a 4Gbps capable EC-equipped Sandy Bridge or newer notebook instead to get easier eGPU connectivty, faster performance, plus newer NVidia drivers with better performance and more video card support. http://forum.techinferno.com/diy-e-gpu-projects/4109-egpu-candidate-system-list.html#post57511

Hi, i want to ask a few questions about eGPU for my laptop.

Here's the detail:

Samsung 535u4x

8gb ram

a8 4555m 1.6ghz

Display VGA Dual Graphics with 1GB gDDR3 Graphic Memory

win 7 64bit

PE4L pm060a ver 2.1 (mPCIe)

PSU 500w

HIS Radeon R7 250 1gb ddr5

i've tried to plug in the PE4L mpcie cable to laptop wifi card slot before boot up the windows. When i was booting up the laptop went BSOD (atikmpag.sys error, i've already check this error it was a driver error from amd).And i've tried the hotplug too (sleep mode the laptop, turn on the egpu, plug in the cable, resume my windows) and when i check on device manager, it wont scan my ext VGA.

Here's the screenshot :http://i59.tinypic.com/nxw2ub.jpg

Tried to switch SW 1 and SW 2 repeatedly it's still doesn't works

My questions:

1. Did i miss something like setup 1.xx (as Tech Inferno Fan said) should installed to fix this?

2. was the Radeon R7 250 supported to do an eGPU?

I've seen many peoples were succeeded to run eGPU with Radeon HD not the R series, maybe the vga was supported only on pc desktop

Thank you very much!

I don't use my laptop as a portable one any more. Also it is standing on one book for better cooling, which will facilitate plugging to the mPCIe. I saw mPCIe extender in the form of narrow and wide cable somewhere here. I don't know whether it has good enough screening but it should be more convenient.

About the EXP GDC V6. From your link I find about possible "faulty mPCIe/EC cables". Don't want to risk now. The PE4C V1.2 has ATX 24-pin slot to conveniently turn on PSU, supports Linux and seems to be better in avoiding registration problems when booting. It is only $18 more expensive. Just want to be sure first that I don't need to solder the cable to the 2 units.

Also I have to note that I have Windows XP SP3. I saw confirmations that an eGPU can be recognized in WinXP. One may need to log out and then log in for this. But Optimus may not work albeit nVidia still release drivers for WinXP. I'll try Ultramon if fail with Optimus, or will try installed Linux or plug in external monitor. Win 7 or 8 will hardly ever be installed. First I should better upgrade HDD. And I have GMA950, not a HD iGPU. I haven't got whether Optimus is possible in this case but with smaller performance.

I have plans to buy a new laptop but that will be later. Now I would like to have temporary solution. Also the new laptop can have troubles which the current one will not have. So there are several reasons to try eGPU on the current laptop too. And as you mentioned, newer nVidia drivers can have no Optimus support.

And again about bandwidth. I didn't take into account bitmapped textures (compressed afaik) if they are loaded frequently. Don't recall about other informationally consumptive ingredients. Then transfer to the eGPU becomes comparable with transfer from the GPU (if used). But if I reduce resolution I have good chance to play a game with high or low details but the eGPU will work. Is there a known case when a game could be played with 25+ fps on eGPU because of low bandwidth of mPCIe v1? So "unsupported" videocards may be unsupported only relatively (but still be able to reveal better performance) if I understand everything correctly. I am also curious about eGPUs perspective as they are so convenient.

Update: Here is the source, where GPU switching in WInXP is said to be possible by mean log off/on. At the beginning I though that will be enough to disable iGPU in Device Manager. WinXP may be not smart enough. By the way, since some moment, if I am not wrong, there appeared the copy of IGPU. Also I have 3 monitors in Device Manager...

hi guys, just bought myself a dock and psu along with a gts 450 for my X200 P8600 with 3gb RAM (it was 4 but all the chat suggests 4gb is more hassle than it is worth).I was only able to get it all to work after flashing to the latest bios since doing that it loads the card through the TV/HDMI socket it wont display through the laptop and when it does load it does so at the expense of the internal intel graphics which cease to appear in device manager.I have tried plugging in the dock after the bios screen appears which causes a error 12 to appear over both. When I benchmarked with single display I only get a 3dmark 06 score of 4k, is this an indication of the optimus technology being disabled and if so how can I enable it? I puprosely built this to replace my Dell L502X which returns a score of 8k on 3dmark.Any help would be greatly appreciated.

I have some questions about the Setup 1.3 that I'd like to have answered.

Can you change the countdown time in the setup 1.3 menu (the one where you select the automated startup/menu/console)?

Is it possible to auto-boot all the way to windows 8.1 through setup 1.3? Like could you set boot default to setup 1.3 then chainload to windows 8.1 manually or do you still have to manually select windows 8.1 after chainloading?

Thanks in advance

Hello everyone!

I just wanted to join the community after skimming the website for a couple of weeks and plan on making an eGPU setup for the next 2-3 months and want to ask for a few questions.

((((((((I have a Win 8.1(64bit) )))))))))) additional info

I want to ask if where can I buy a pcie X16 adapter with a free setup 1.30 or setup 1.x or whatevs XD.

I cant seem to find this website "Harmonic Inversion Technology" (HIT) I only see ads and it looks like their website is down.

I want to do this so I cant make much of a hassle with a friend because Im asking him to buy this online and I dont want him to buy again Its too much of a hassle

( ITS COMPLICATED SORRY)

(Just think of me as I am low on budget)

Thanks for any reply :)

Setup 1.3 has to be bought separately. Previously it was free for everyone but companies abused the TOU so it now costs money. If you are using win 8.1 and have a PC with uefi or a Mac I can help you parse your partition to efi which makes egpus nearly plugnplay

Not the guy you were talking to, but I'm curious how using UEFI would affect plugnplay-edness

Win8.1 UEFI install often resolving error 12 issues in Macbooks and HP Elitebooks. HP Elitebooks also gaining hotplug capability when moving from a MBR (BIOS) to UEFI install.

Likely reason for this is during bootup, the firmware UEFI framework does a more comprehensive PCIe device configuration than when a legacy boot it used.

Hello everyone.

It seems to me after spending countless hours that i have to buy set up 1.30 for all this to work.

I that true?

No its not hours mate just read and follow the instructions given to you by Tech Inferno Fan, if you are able to understand the whole concept of it, in no time your setup will be up and running

Can anyone please tell if I do set up 1.30 or whatever, will I need to do anything else?

Please follow template at How to ask help efficiently? in presenting your problem.

So far we know you have a GTX760, are seeing an error 42 and having problems getting the internal LCD mode to work. No other detail on what hardware you are working with makes it difficult to give an response to your questions.
