An open project looking to expand the (Dell) Alienware Graphics Amplifier (Caldera) to support Nvidia RTX 3000 and AMD RX 6000 series GPUs.
This project is designed to probe and potentially expand GPU support in the Alienware Graphics Amplifier (Caldera) to include Nvidia RTX 3000 series and AMD RX 6000 series GPUs. As of this writing (11/19/2020), Alienware (Dell) has indicated that AGA is "soon to be end of life", and "will not be validated with RTX 3xxx video cards". (Source)
Support for AMD RX 6000 series GPUs at the current time is unknown.
Requirements: Windows 64-bit Operating System, .NET Framework 4.8
Test Setup
Ensure that an Alienware Graphics Amplifier is attached to your PC, with a GPU (working or not working) inserted in the AGA, with all necessary power cables plugged in.
Download the executable ('OpenCaldera.exe') to and double-click to run; it should open a Command Prompt window and write brief output to the screen.
Expected Output
Under normal Graphics Amplifier working conditions, the following is the expected result. As of 0.1.x.0, I'm looking to gather information on how this is presented in Graphics Amplifiers with RTX 3000 and RX 6000 series GPUs installed.
Where should I report my output?
Please register for GitHub, and submit your feedback under "Issues". There is an open issue titled "0.1.0.0 Results" for output specific to this initial version.
Registering for GitHub may be less than ideal for some of us, but I don't want to rely on any one forum post for updates (as it can be buried, and not all users will subscribe to all forums.) GitHub has the advantage of offering the 'Watch' feature on this project (above, right), which will notify those who choose to "watch" this project of updates via email.
Will/can OpenCaldera damage my Alienware system, Graphics Amplifier, or GPU?
No, at worst, you may need to reboot your system. However, this is exploratory, and I assume no liability.
At the moment, RTX 3000 series GPUs will initialize and be recognized by an AGA, but show up in the Device Manager with an exclamation point on the device, indicating a problem. Please add troubleshooting data related to this as an 'Issue' in the "Windows Error Reports" Issue. Specifically, screenshots of the Device Manager (and it's corresponding error), as well as Windows Event Viewer errors (screenshots/logs) are helpful.
| Manufacturer | AIB | Make | Model | Product Name | Working |
|---|---|---|---|---|---|
| AMD | Reference | 5700 | XT | Confirmed |
I'll continue to investigate support for RTX 3000 and RX 6000—and provide updates as I have them. At the current time, it isn't clear if the issue preventing RTX 3000 series GPUs from working is a software, driver, or firmware issue.
I do not have an RTX 3000 series nor RX 6000 series GPU at the moment, so I cannot confirm whether or not RX 6000 series GPUs from AMD might be compatible already, nor can I do advanced debugging and troubleshooting. If/when I get either, I can dive much deeper. Until then, I'm trying to collect information and probe what's possible.
Yes! This is open exploration, and anyone is welcome to participate, in troubleshooting, exploration, etc. I welcome collaboration and want to find a solution for all AGA owners to benefit.
The Alienware Graphics Amplifier is the best eGPU enclosure available—although restricted to Alienware systems, it offers a direct PCIE 4x connection to the CPU, without the overhead and/or bandwidth penalties of Thunderbolt 3.
For myself and many others, it's allowed our laptops to stay cooler while gaming (as they're only cooling the CPU, the dGPU is disabled), and afforded us the benefit of a full-size, full-powered, desktop-class GPU.
It's true that the dGPU in laptops today are stronger, comparatively, than those offered with the Graphics Amplifier initially debuted—but it is still the best option for gaming performance increase for laptops, new or old.
And, because it's a PCIE 4x enclosure with an ATX-compatible Power Supply, I don't believe it should restrict the options of the user. At the current time, Dell is indicating that they will not certify it on the 3080 and 3090 series GPUs from Nvidia, because the built-in AGA PSU is rated for 460w, and can't meet the (potential) power requirements. That's fair—but it's also fair to inform customers and allow them to upgrade and replace the built-in PSU, just as they would in any desktop PC, to accomodate.
(Additionally, the expanding size of GPUs means fitting properly within the Graphics Amplifier is another challenge, which most likely contributes to Dell's decision not to certify 3080/3090 series. I believe this, like the PSU requirements, is best left to the customer. There are many RTX and RX series GPUs that should fit comfortably without any modification; so far, an FE 3070 and (I believe) Reference RX 6800 will fit without any issue.)

I was able to purchase an AMD Radeon RX 6800, and it works just fine in the AGA, where the RTX 3070 was having so much difficulty. I've posted my findings, including opinion on the subject, here: https://www.reddit.com/r/Alienware/comments/jxvnga/project_opencaldera_exploring_adding_unofficial/

TimeSpy 3DMark Benchmark found of a user with an Alienware M17 R3 and 3080, presumably via AGA: https://www.3dmark.com/spy/15417032 If you are or know this individual, please ask them to contact me.
