Hi, I have bios A16 there is no way to disable the built-in video card, this can be done by setting Setup 1.30, or flash the BIOS on the unlocked (there should be such a possibility). You disappear from the manager built dGPU 650M?

Hi Megaxxx, yes, my eGPU is not visible in Device manager. I'll wait for any advise or do you have any ideas? Do you also have the 3D version of Dell 7720?

@Nando4 is probably the best techpro guy here... so I guess answer from him might be most helpful for us.

Thank you

you should provide more details. like when you are using GTX 660, then you are not powering it from PSU - because your PSU has no PCI-E power cable. It probably has not got enough power.

In case of 8600GT - it draws max 43W (Video Card Comparison - GPUReview.com), but I am no expert on this matter - I do not know if Beast can supply that much power from PCI-E lane alone or if such old card is at all supported. because this card only supports PCIe 1.0 x16. Experts should comment if he can use it by default, he might need some 1.3 setup or whatever to switch to PCIe 1.0?

Hi,

right now I am testing third GPU - Nvidia GTX 745 (OEM). This one should take 55W and min power requirement 300W (it has no 6 or 8 PIN so power goes only to GDC Beast).

To be sure, I tried another PSU - ATX 300W from older desktop (I m lucky to have that HW around...)

Unfortunately, still the same result. my eGPU doesn't get detected in Device manager at all !! Tried to turn it on/off as described, plug/unplug, uninstall Nvidia drivers... only what I got is that after reboot it will install again my dGPU 650M... iGPU is not visible, too, (what I read) because my laptop Dell 7720 has 3D screen = no Optimus = Intel HD 4000 never visible...

Am I missing something? Could Setup 1.30 solve this damn issue pls ? Are any other options to try? Red light is on, fans are spinning, miniPCI is instead of wifi... Malfunction of GDC Beast?

Thank you guys, this answer could definitely help also to another user here, Megaxxx, who has probably the same laptop as me.

EDIT: to provide more details about my testing:

- I guess my TOLUD is 3GB (on image below)

- I didn't uninstall the Wifi drivers, will do after this post (image of wifi module below)

- each time I plug/unplug eGPU my screen goes black - that is weird, especially because no eGPU found in Device manager

- using Windows 7 64bit

- in my BIOS I don't see any option to disable dGPU

Hi everyone,

Beast arrived today and after few hours of chat with rgpu (to who I am really thankful), we can't figure out my issue. In points:

- laptop Dell 7720 with dGPU GT 650M

- today updated BIOS to latest A16

- laptop has 3D screen and iGPU Intel HD 4000 is not visible in Device manager (it means 650M is the only available card)

- EXP GDC Beast is supplied with ATX 400W PSU

- using miniPCI version instead of wifi

- today tested GTX 660 and older 8600GT cards

- neither one of them was visible in Device manager - neither one as VGA adapter

- with rgpu checked the cable connections, all are good

- eGPU not visible in Device manager, but if I turn off the power supply, my laptop screen will become black, hard reset required

- I tried the same steps with disabled/uninstalled 650M, no progress

Thank you for any help, much appreciated. I will post any photos if required.

Thank you once again

I dont know what you mean by provided black (with EC yellow) 4-PIN connector (Im not hardware guy), all I know:

DO NOT USE THIS 4-PIN: http://www.play3r.net/wp-content/uploads/2013/04/Be-Quiet-Pure-Power-L8-530W-20+4-Pin.jpg (this is part of ATX 24-PIN motherboard connector (20PIN+4PIN);

USE: 4-PIN labaled "CPU": It should look something like this (4PIN+4PIN): http://www.corsair.com/Media/catalog/product/c/p/cp-8920115_eps_12v_cpu_conn.png

I'll use this one (it should be included in order) - http://img.banggood.com/images/2014/tanghong/07/SKU149984/SKU149984-62.jpg

Or, at 1:22 in this video

I see your card uses 140W maximum: GeForce GTX 660 | Specifications | GeForce

So it depends on your power supply - if it can provide that much power, then yes, DC input is enough. Im not sure, but I think mPCI-E also feeds the card with a little power, but nothing to rely on - dc power should provide most power for the card, just to be safe.

And if you are not hardware guy like me - be careful if you chose to feed the card with ATX PSU - use correct 4-PIN connector.

Ok, friend will give ATX PSU 400W, that should be enough for all except Hubble As you wrote above, between PSU and eGPU I'll use provided black (with EC yellow) 4-PIN connector. Will test with friend's Nvidia 8600GT and then with GTX660 . Regarding laptops, main goal for testing is mentioned Dell 7720 17r SE, I'll try to test it also with another laptop HP dv6600 - result might be helpful for all others.

Order is getting shipped now from UK warehouse, next week it will be in my hands I hope.

In my opinion it comes down to 2 things:

1) chipset: on this depends speed of the PCI-E port

2) BIOS: on this depends if the external card will be detected and allowed.

I have the same chipset as you and Beast (v6.1) works flawless for me. I even have same CPU and IGPU as you.

I finally received a Beast replacement (I destroyed my first one by connecting it incorrectly - used wrong 4-PIN power cable from ATX PSU).

So now I can confirm - I have used two Beasts. Both have Gen2 speed on my setup (with Nvidia GTX 970 external GPU).

Today I had 6 hours of gaming one of the latest games (Evil within - assignment) on 1080p max settings at 50-60 FPS. Laptop did not crash once.

So as for your Dell laptop - it only comes down to BIOS, if it allows unapproved hardware connected to PCI-E port, then you are good to go.

to make it short - you can go and buy whichever adapter you want and you will be happy with it. if you chose beast - remember, you can get 8% off the price - just look for my first post on this forum.

Thank you very much man, ordered with your coupon code, will keep you and Megaxxx updated about my status... I hope the only problem will be BIOS, (now using Dell Inc. A03, 13.7.2012). On Dell website is official update to BIOS A16 which should fix the invisibility of iGPU Intel HD 4000. And after that it should also allow to disable dGPU GT650M. Wish me luck!

As a power supply I will try simple DC input, first card for testing should be GTX660 and if I'm not wrong, 12V DC power supply should be enough. Or am I wrong?

Thank you again

Hello Megaxxx, as I see you have the same laptop as me and I asked the same question. I want to order Beast and test it first with some cheap eGPU. Please, keep me updated how will work PE4C, I'll do the same with Beast. Any experience can help to each one of us.

And weird that no one described experience with our Dell 7720 yet, its an excellent laptop and eGPU can make it even more powerful.

Thx

Hi guys, I am new here. Please, does anyone have eGPU experience with Dell Inspiron 7720 ?

Chipset: Intel HM77

iGPU: Intel HD Graphics 4000

dGPU: Nvidia 650m

RAM: 8GB

CPU: i7-3610QM

Thank you thank you thank you

Hi guys,

I am few clicks from ordering either BPlus or Beast... but to be really sure, if anyone of you have any recommendations/experience with this laptop, please help.

Link for this laptop:

Review Dell Inspiron 17R-SE-7720 Notebook - NotebookCheck.net Reviews

For this chipset should work miniPCI (instead of wifi).

Which one should work better?

Any possible compatibility issues?

Setup 1.30 required?

Recommended GPU ?

Stuttering, BSOD?

Anything you know might help, thank you once again.
