Wow, I'm getting a bit lost, I'm using the same PSU for fans and GPU. When the fans are connected I have no more Gen2, without them everything is fine.

How many power rails you are using to connect to the graphics card?

I suggest you to not connect fans on any of the power rails which you are connecting to the card. (power rail means each group of 4 cables(yellow, 2 blacks and red) from smps which generally has multiple sockets on it )

@angerthosenear @Tech Inferno Fan

now the graphics card is detecting properly on my machine, thank you very much for your help and time.

I replaced the expresscard connector(which had couple of damaged pins).

Only thing that remains now is to activate Optimus. I have intel GMA 4500MHD but I don't see Optimus activated.

here is my GPUz

System:

Dell Vostro 1015

Intel Core2Duo T9600 (upgraded, earlier it was T6570)

6GB DDR2 RAM @800mhz

Chipset: intel GM45 express

iGPU: Intel GMA 4500 MHD

Hard drive: 250gb Samsung(840) SSD

Dell Bios Revision 06

I will do benchmarks and post the scores soon.

Also, I will try to make my setup more modular and fit it in a container.

Will provide you updates soon.

---------------------------------

Update: I am getting blue screen fatal error after some time playing World of tanks.

I get it even when computing windows performance score.

Wow, sure enough you do not have a single DWord entry. Not gonna lie, I kinda guessed here. In mine, the DWord stuff is under the 'Name (BUF0, ResourceTemplate () ' section. I located the BUF0 in your dsl file and found a 'Memory32Fixed' entry, I do not have this in mine - not really sure what this does. I added the QWord entry into this BUF0 spot (since it is the same as in mine). Not sure why yours is so dramatically different.

Possible DSDT override file:

Screenshot of what I am talking about:

(My QWord is at the bottom of that list / way off screen).

No guarrantees if that will work. I guess worth a shot.

The HPET is High Precision Event Timer., also the "Memory32Fixed" must be some function which fixes something in the passed addresses.

btw, I tried to compile the dsdt you gave, but its throwing errors,

http://forum.techinferno.com/attachment.php?attachmentid=9774&d=1385662981

I am starting to doubt if I need different version of dsdt editor?

Are there any new versions?

@Tech Inferno Fan can you guide me regarding this?

Since disabling the inbuilt SDHC gave you some PCIe space to allow it to be detected, a DSDT override would be useful in this case. What OS are you running?

Are you connecting the eGPU while the computer is off? I know there are some things when you put the computer to sleep and then connect to sometimes to get it working.

If you get your .dsl file, I can edit it for you (just upload it somewhere).

That black screen problem seems really odd.

@angerthosenear I really appreciate your help.

I have uploaded my dsl file at http://techrevol.com/egpu/dsdt-sameer-original.dsl

Also the blank screen problem in real was extended display. my desktop was going on the external display so nothing was there on the laptop display. However I did not see any output on external display.

Today I have reinstalled windows and its not detecting egpu again : I think i need the dsdt override.

Thank you very much.

@angerthosenear thank you.

Btw, my system is now detecting my egpu. I had to disable the inbuilt SDHC Cardreader from BIOS for that(that freed up some PCIE space i guess).

@Tech Inferno Fan

Now when I attach egpu(self soldered ), my screen goes blank and after few seconds only the mouse cursor appears on screen.

I can see right click menu but when I select something from it, its not displayed.

Is such kind of problem encountered before?

I was just trying to do DSDT Override(assuming low memory space cause of the blank screen problem), but the generated .dsl does not have any DwordMemory entry

Also, the Nvidia control panel does not open up as I am running from my igpu.(it says nvidia control panel can not be opened because the system is not using nvidia gpu)

How can I rectify above?

Hello guys

I already have "large memory" entry in my device manager.

Will I still need DSDT override?

My machine config is

Dell vostro 1015

Processor: intel c2d T9600 (I have upgraded from the original t6600)

chipset: intel GM45

RAM: 6GB @800mhz

I have already soldered my EGPU by using @sonny_mv's pin diagram,

but its not detecting the card so far.
