@Alex.sg91 : Hi !

Sorry for late reply. I did not get e-mail notifications.

I know akbar bios and I think I also have it installed. Not sure though.
For me, Nando software is useful for compactation and setting Gen2 speed on eGPU port and works flawlessly.

Without it, it wouldn't work as I would get error 12 (resources) and DSDT override is complicated.
Usually. when you boot, you should come to choose between windows and eGPU setup.
But, you seem to have problems even before that.

 

When you boot with eGPU plugged, can you even get to bios ?
If not, I am not sure what advice I should tell you.
I did not modify settings in BIOS. I installed a custom one only to see if I can overcome heating problems and modify fan speed, but this is another story.
In BIOS I only set Integrated on video mode or something so dGPU is disabled.

Did you do any major modifications in BIOS ?
 

Trackpad and keyboard disabled might suggest a major BIOS modifications and resources cannot be allocated to them.

 

Maybe you could try with official Acer BIOS and see if the booting works properly.

 

If not, probably GDC adapter is faulty.
When I got to eGPU, I wanted to make a sure investment and went for Nando's advice and got my adapter from hwtools.net.

In the future, please use @mynick , as I might get notifications on email.

Good luck !

@Arbystrider :

 

Thank you for your advice.
Now I have a really old PSU I borrowed with 350 W, ATX 1, no power ON/OFF switch :))

Those from that site are cheap, low power, but in their description I find lots of protections.
I will see when I will get some money.

Latest news :

 

I managed to damage my PSU with ...water :))

Luckly, PE4C and 750 Ti ar still working. (tested with other PSU)

 

I see on nvidia site and other sites that benchmark/test stuff that 750 Ti uses ~70 W.

 

Soo, can I buy a PSU with under 400 W ? (Logically yes, but ..)

 

Can you suggest a cheap model from here ? http://www.emag.ro/surse-pc/filter/putere-sursa-w-f72,sub-500-v66/sort-priceasc/c

 

Thank you guys !

Edited 1st post with additional informations and observations so far.

@Arbystrider : room temp 20-25 Celsius

 

Those temps I noticed mid-game after about 1 hour.

@templeka : Guess what ? After some testing, It works with 36/64 bit without DSDT

 

Full report here :

 

Hi !

First of all, thank you for all the informations posted around the forum and to this great community !

 

So, here is my succesful setup :

• Notebook 15" Acer Aspire 5750G

• Intel Core i5-2450M

• 15.6" HD LED LCD

• 8 GB DDR3 RAM

• Windows 7 64bit

• Nvidia GeForce GT 630M (dGPU)

• Intel HD Graphics 3000 (iGPU)

• Gygabite Windforce GTX 750 TI OC2 2GB DDR5 RAM (eGPU)

• PE4C-PM060A V3.0 Gen3 (mPCIe)

• Segotep SG-D600 (ATX power supply)

• eGPU Setup 1.3 (Tech Inferno Fan)

 

Some pictures first to show the hardware setup : http://postimg.org/gallery/i20gkbj6/

 

Hardware installation was easy.

TIP : Although a great adapter build, DO NOT force cables, slots etc... Have patience !

 

As you can see in the pictures, I had some trouble :

• cable direction is right towards mouse
• I had to cut a piece from my laptop to make room around mPCIe slot
• improvised higher stand for laptop to make room for the cable
• did not figure out how to make a confortable DYI case, yet

 

eGPU setup 1.3  :

• check all hardaware is connected and ATX is set ON
• boot into BIOS > set video from "switchable" to "integrated"
• reboot
• boot into DYI Setup 1.3
• choose 3rd option with menu-based
• startup.bat > Reset
• Chainloader > use mbr
• PCIe ports > hot reset port > nvidia
• PCIe ports > Gen2 link > nvidia (you should see a change in the right table : the alloc size goes from 128 to 512)
• PCIe compactation > endpoint > 56 25GB 36bit
• PCIe compactation > Run compact > eGPU > none
• startup.bat > test run
• chainloader > test run > win7

 

Benchmark :

• internal display used
• CPU hyperthreading enabled
• 3dmark might be inaccurate due to the warning from pictures
• GPU-z confirms x2 link speed
• Currently I play WOT, GTA 5 and they work flawless with at least high settings

 

All in all, it does the trick and I am very satisfied with it.

Most important, Acer temperature problem disappeared.

On load, now I have max 55 Celsius on CPU and 44 Celsius on eGPU.

 

Good luck !

 

Last edit :

Just some update on what I have noticed.

 

1. On every boot you should :

• go to DYI eGPU Setup
• choose "menu-based" option
• PCIe ports > Gen2 link > nvidia (you should see a change in the right table : the alloc size goes from 128 to 512)
• startup.bat > test run
• chainloader > test run > win7
• I always open Device Manager and GPU-Z to see if any problems occur

 

I do this because the gen 2 link retraining is neccesary every time.

 

2. Sometimes my laptop kind of "forgets" about the eGPU. Not sure why, but rarely happens.

 

To check if eGPU is still functional do this :

• check Device Manager for any problems on display
• open GPU-Z
  • you might notice some of the options/informations are grayed out
  • if so, go to Device Manager and disable/enable eGPU display.

First time I looked wrong.

I did that from setup after posting and it worked.

 

Not sure if it will remain on the next boot

Not expensive enough for gaming PC :)) 

 

Just the adaptor.

 

P.S : GPU-Z reports 1.1 ...

My laptop says it has PCIe 2.0

hmmm ...I think I have to DSDT override or Win7 trick so I can make 64bit compactation.

Any other suggestions ?

@Arbystrider : aww man...,

Why not ask a friend who has a credit card or something ? 

 

Yeah.., I followed nando suggestion from some of the topics + I read comments on GDC products from amazon ebay etc and many people had hardware problems with it.

 

So yeah.., I choose to go for safest option although a bit more expensive

@templeka

I have 2.0 which is good.

Sadly yeah.... Taxes over taxes...,

 

On mfactor the adapter is 55$ and shipment via dhl international is +40$ and with postal but no tracking is +20

Check it out and see estimate shippment tax.

 

Never tried GDC but I surely like how good the adapter is build woth good soldering, cables etc.

 

My dad is an electrical engineer and he said it is really well done.

 

RO : nu e carpeala si nici chirpici. Iti pun niste poze daca vrei

Hi again ! 

Did not see your post last night.

So, I started egpu setup and did 36 compactation and choose option "igpu egpu" and scope the same option.

It started without problems.

 

Nvidia control panel had "let 3d app decide".

First benchmark with 3Dmark Firestarter from guru3d site got me 3700 pcts which is good I guess.

 

I used Geforce experience for World of Tanks and got all settings maxed and ran at 60 fps without problems vsync on.

 

I am satisfied with the results so far.

 

@templeka : you are right. If not broken, don't fix it principle :))

I bought from hwtools.net through paypal.

Other variant was to order from their principal distributer mfactor from USA, but meh.. Just a choice.

I paid 65$ for PE4C + 22$ shipping through paypal.

It was delivered by DHL from Taipei,Taiwan and had to pay 70 Ron (15$) custom taxes + 100.8 Ron (25$) for letting DHL pay my custom taxes and receive the package faster.

 

Other option was to pay custom taxes myself, but I would need a code from Trezorerie which would take 3 days only for this step.

 

The product itself is really well build with strong soledring and stability.

I was amazed.

 

Good luck ! 

 

P.S : best part is that now i do not have problems with laptop heating.

 

Previously with dGpu i had to use acer fan utility to get the fan at full speed and still got above 80 degrees C temperature and of course video and sound stutter.

 

Now I dont use the utility and Cpu temp is 50 and Gpu at 36 

 

P.S 2 : how do i know if i did  optimus 1.2 ? Or that is only for gen1 pcie ?

 

P.S 3 : After a succesful chainload test, a session of gaming and shutting down....
When I boot, I have to go to setup again and Chainload > Test run or just boot with windows ?

Hi again !

So I got all the parts and installed them.

 

I had to cut some extra support from tge adapter to fit the mPcie slot and also cut some plastic from that area.

 

The cable is pretty stiff and has some strength so I wanted to avoid bending it.

 

Some problems occured : 

I have to improvise some extra feet so laptop does not sit on the cable.

Direction of the cable goes right and there is a bit discomfort with th mouse, but manageble.

 

I set from Bios Integrated, followed Tech Inferno Fan instructions for the eGPU setup and installed nvidia drivers for desktop succesfully, but :

- setting pcie compactation to 36bit gives error 12

- setting to 32 bit worked.

 

Is there a difference ?

Also first trial I set compactation for "eGPU" and second I believe for "iGPU eGPU" option.

 

Should I try 36bit for iGPU eGPU" option ?

 

Did not have time to benchmark or test a game.

 

How should I try to get optimus or best config ?

Did you guys fix it ?

@Arbystrider

Thank you !

 

Not sure how will it work with driver swapping, but I will give feedback on monday or tuesday.

So 24-pin from atx to adapter and 6 pin from atx to video card. Hope it does not fry or something :))

Video card, ATX and egpu setup aquired.

Adaptor should arrive on monday.

 

What driver should I install ?

Driver for desktop 750 Ti or for notebook 750M ? 

 

Sorry for double post.

For some reason i do not see edit button from android

 

 

L.E : other question : should I power the video card through PE4C adaptor or directly to ATX source ?

Thank you very much !
I will post feedback as soon as I get them assambled.

• Gygabyte GeForce GTX 750 TI OC2 Windforce 2x 2GB DDR5 128-bit
• PSU Super Flower SF-550K12XP v2 550W
• PE4C-PM060A v3.0
• possible eGPU Setup 1.3x

I hope for the best.

That is good news.

Thank you for reply !

For the budget I think I will go for a Gygabite Windforce GTX 750 TI OC2 2GB DDR5 RAM

 

And for adapter PE4L or PE4C ?

I've seen an implementation that Tech Inferno Fan made around the forum and I indent to go for PE4L as it worked

Edit : I cannot seem to find PE4L 2.1b to buy on aliexpress, mfactor ..
I think I will have to go with PE4C 3.0 ... not sure if it will work with my laptop

Hello !

I got a little problem understanding eGPU setups.

 

My specs :

• Acer Aspire 5750G
• Intel Core i5-2450M
• 15.6" HD LED LCD
• Nvidia GeForce GT 630M
• Intel HD Graphics 3000
• 8 GB DDR3 RAM

 

I guess I have Sandy Bridge, Intel64 Family 6 Model 42 and I guess it supports PCIe 2.0 on southernbridge and I can use only mPcie Wifi slot for eGPU.

I am from Roumania and I can only find Gtx 750, 750 Ti, 950 and variants of them which require PCIe 3.0.

• PE4C has Pcie 3 support so might go along with those graphics cards.
• PE4L has pcie 2 so might not work ?

 

If this is the case, i guess i need a GTX 600 series or a graphics card that goes with PCIe 2 to be compatible with Sandy Bridge.

 

Or I can use PCIe 3 grahpics card with PE4C for PCIe 3,but on my laptop will perform as for PCIe 2 ?
