15 R3, GPU Bus interface, x8 internal 1070 GTX, x4 for external 1660 GTX?

Edit : sorry did not know you could not edit post here made it more readable.

Hi all, I noticed that the bus interface on the Alienware 15 R3 Laptop that the GPU Bus interface is only @ x8 internal gpu 1070 GTX.

I brought the external graphics amplifier and installed an external GPU 1660 GTX, but its only running @x4 not @ x16

I always thought my system had a graphics problem from day one, but could never pinpoint the problem, till now. I have to say i'm very frustrated with the fact that both the 2 GPU's are only running at the old AGP slots speeds of x4 and x8.

Again Have to say I'm disappointed with the amplifier, because if its only going to let me run the external graphics card @x4.

So what was the point of spending the money to buy it, and the graphics card, in the first place if bus interface is so slow?

Yes, I am having slow downs to the point I could not plays games, so I brought the  graphics amp and that did not fix it, so I reinstalled windows and have a fresh install and all the drivers, my laptop is still running at 92 deg c when playing games online even with the laptop elevated and extra fans. 

This information should be given to people when buying the system, and it dose not change the fact that the internal gpu is not running @ x16 even if the external is on a sata lan connection. 

If I had of known that the internal bus was limited to @x8 I would never have brought a gaming laptop and just brought or built a new pc. These spec's have not been given anywhere i have read for this laptop. By limiting the bus to x8 you are not getting the full speed of the chip, Because if i did get full speed of the 1070 gtx I most likely would not of had to upgrade again with the graphics amp just to play games, that is now only connected at x4 and that is worse speed then x8.

Have a new keyboard:

I have to say that the bottle neck is a big limiting factor to the laptop and future designs if you are limiting the bus speeds for the chips.

I say this as a mother board can be built with 2 x 16 full speed as a standard, and do can not see why it could not be done on a laptop interface.

I think i will have to save up for a new build all I need is motherboard, ram and cpu have the rest here. I will give this laptop to my mother when i have built the new rig.

How do i go about getting a new keyboard for my laptop as i have warn all the black off the letters and all you see is the back light through 80% of the keys? 

I can rebuild the laptop myself so replacing the keyboard is no problem.

Also the Graphics Amp needs changing to it's casing size, I can not shut mine because the 8pin power leads that plug into the graphics card push the lid up, and if I force it shut the graphics card will not register, so I have to leave the top up, leaving it open 5cm at the back of the Amp case. 

@Alienware Area-51 ALX 2006  You said, "The Graphics amp bus interface is only limited to x4 and that’s all. Older models had a full speed x16 interface but the new ones are limited to x8."  First of all, I don't understand why you said x4 in your first sentence and x8 in your second sentence.  But more importantly, can you provide links to official documentation or some other official source to show that older AGAs used PCIe x16 while newer ones are limited to x4 (or x8)?  And this is the second thread I've seen you talk about other eGPU enclosures like the Razer Core going through "LAN and SATA".  What are you talking about there?  Other eGPU enclosures use Thunderbolt 3.  That provides a PCIe x2 or PCIe x4 interface, depending on the system design.  I'm not sure how you think LAN and SATA are involved.

Thanks for your help sorting out my question Alienware Area-51, and the link to the new keyboard. 

No, I was talking about the Alienware Laptops.

not the Graphics Amp lol.

I have been researching the chipset and software that runs it.  Just by changing a few setting from manual to auto and also install Turbo Boost drivers 2.6 for my chip as the Alienware 15 R3 dose not have these drivers installed.

I can now get 3.4gig out of my 2.8 gig chip.

The laptop seems to run a lot faster, and respond quicker to movies and loading the browser have not tried gaming but feel its only going to be better now. 

Intel turbo boost technology monitor 3.0 and 2.6 link 

After you have download the 2.6 driver and installed it for the Alienware 15 R3.

Press [Win]+[R] and run "services.msc".

Change all intel settings from manual to automatic

Then Reboot your system

My system benchmark result Cpu-z 

Hope this helps some of you get more out of your machine without trying to over clock it with overclocking software.

Cool!

I Overclocked my Alienware 15 R1 from 2014 from 2.5Ghz to 3.7Ghz on all 4 cores.

If my laptop is cold and my room is at 59 degrees F then I can push it to 4.1Ghz but then it surprisingly draws up to 35watts of power under load. This CPU can handle its stuff well since this is the first generation BGA cpus Alienware designed.

Dont worry about my temps, they’re in a 75C range under a 4 core stress load.

Yeah it's good to have my system running right now, and it also runs cooler while running games it was 60c to 68c last night playing Doom Eternal and was running very smooth.

I installed Intel Processor Identification Utility Windows Version I noticed that they cpu is at 3.46 GHz and now has access to 6mb L3 memory cache, where it has no access to it without the turbo boost installed and enabled.

Also I installed Intel Turbo Boost Max Technology 3.0 Application on top of the 2.6 version I installed before it was the only way i could install 3.0 as i could not install 3.0 from the other link page on 2.6.

That’s good.

Yeah it is real good, also my system has been 10 c lower in heat since I have done the mods.

I have a question but, is the AGA built on PCIe bifurcation. If the AGA port and hardware was built on PCIe bifurcation this would explain why it can only be PCIe x4 because they have got usb ports and such in the AGA case.

PCIe bifurcation supported hardware can only have a x16 or x4x4x4x4 ( "you can get cards to split single PCIe x16 to x8x8") 

If this is the case, the external AGA would be set to x4x4x4x4 in the uefi/ bios, am I right?. It is just that we can not access this function, not home users anyway, but only Dell developers.

Right, only dell developers can have access to the PCIe interface speed.
