Toshiba satellite - need some advice

Hello people!

 

I've been thinking for some time now about adding an eGpu to my system to play some newer games, but not everything is clear in my mind.
I have a Toshiba satellite with an Ivy Bridge i7-3630QM, 8gb of ram and only a dGpu (hd7670m). The iGpu is disabled and even if I enable it through an unlocked bios, it results in a non-bootable machine. So as far as I'm concerned the laptop is dGpu only.
I have "internally" soldered an Alfa usb network adapter, so the mPcie slot is free. On Intel’s website it's listed as 3.0, but hwinfo lists it as 2.0 x1. The TOLUD size is 2.75Gb, and the slot is not hotplug enabled, but I'm also not sure if the network card is whitelisted (it probably is...will try one from another laptop).

Now my question is, is it worth it to implement an egpu solution? I can even now play most "new" games on medium settings on the 1366x768 internal screen and get 30 fps. I'm a casual gamer and don't pretend much, just want to be able to play newer, heavier games.

My main concern is still being able to unplug the egpu and take the laptop to work and do my stuff using the dgpu.
An ideal situation would be gaming on the internal screen, but I'm afraid the 1.1x1 bandwidth will bring me to the dgpu performance levels or even lower. But I have 2 spare 1080 monitors that will come handy if necessary.

So...

Is a mpcie egpu solution still worth and feasible? Is the v9 exp gdc 2.0 connection reliable? Which gpu should I go for? A gtx970/rx470 would be the upper limit due to bottleneck issues, I guess.

I'm a total noob regarding the matter and will be really grateful for kick in the right direction.

 

 

Thank you for your time.

Erikp_9, pls refer to this reddit egpu introductory guide.

EXP GDC was previously hit-and-miss for Gen2 reliability.  An external LCD is highly recommended to maximise the x1 bandwidth exclusively for eGPU use. Be aware too mPCIe eGPUs now has an error 43 issue with GTX10xx cards and gaming performance will be variable depending on the bandwidth they require.

If wanting high performance gaming consider a Thunderbolt eGPU gives significantly more bandwidth. 32Gbps-TB3, 16Gbps-TB2, 10Gbps-TB1,  vs 4Gbps-mPCIe2 (@Gen2).  TB2 (x4 2.0)  is where gaming nears desktop level (over 87%) : https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_PCI_Express_Scaling/24.html

A Thunderbolt system also gives an accessible port, making eGPU docking more convenient.

Thank you Nando.

I almost bought a new laptop, but since I got a gtx 980 almost for free from a miner friend, I decided to give a try to this laptop with mpcie configuration. I have also ordered a pe4c with soldered cable.
I spent a week learning how to remove whitelists and fully unlock my bios. Now I can enable hotplug and 2 of the wifi cards I tried, work with no issues (one ralink and one atheros). Can I now safely assume that the whitelist is gone?
Tolud size is still 2.75Gb, although there are bios options for that (no idea what they do).
After some reading I still haven't figured out how the eGpu
will behave with the dGpu, since there is no igpu (there is obviously, but it is disabled by default and enabling it causes crashes).
Will disabling the dGpu (hd 7670m) in Bios before booting with eGpu and effectively have only eGpu in the system do the trick? Or will it work with both cards on? Maybe it's a dumb question, and case specific, but It still puzzles me.

Thanks

Can you explain how did you unlocked the Bios? I have also a toshiba satellite and id like to do the same

Thats lucky

@Erikp_9 if you want optimus to work and to use the eGPU on the internal display you'll need to activate the iGPU also do DDU and disable the dGPU in BIOS. TOLUD: if....when you connect the eGPU and it doesn't work(showing error 12 in device manager) change the tolud to "DINAMIC" and try again(this is possible workaround,no guarantees but there is no harm either).

IMPORTANT !!!! If you really claiming that you managed to remove the whitelisting i would encourage you to make implementation on HOW TO.There are many here who are stuck and would appreciate the knowledge to fix the problem.Thank you.
