12" Asus Transformer 3 Pro T303UA + [email protected] (Asus XG Station 2) + Win10 [Eugen Sandu]
I have recently bought an Asus Transformer 3 Pro and coupled it up with the XG Station 2. It is a great mix that suits my needs perfectly. The tablet is as portable as I need it to be and the eGPU enclosure is ready to be paired whenever I get home.
The whole setup was easy and I had no issues, except one, but you already know what I'm talking about; it's of course the H2D problem that limits the bandwidth. That being said, I still don't consider it an issue, because if you buy a tablet, you should be aware of the CPU limitations (i7 - 6500u).
If you are one of the poor souls who, like me, knows that there are laptops with far better specs, but still go for tablets, then I hope this guide helps you.
Step 1. Download the bios version 303 ( http://dlcdnet.asus.com/pub/ASUS/nb/T303UA/T303UAAS303.zip ) and the flash utility ( http://dlcdnet.asus.com/pub/ASUS/nb/Apps_for_Win10/Winflash/Winflash_Win10_64_VER322.zip )
Step 2. Install WinFlash, run it and use the Bios 303 that you have recently downloaded. Follow the instructions and wait for the bios to update.
Step 3. Download and install the Thunderbolt driver ( http://dlcdnet.asus.com/pub/ASUS/nb/DriversForWin10/ThunderBolt_Intel_Win10_64_VER16147275.zip )
Step 4. Update your XG Station's firmware ( http://dlcdnet.asus.com/pub/ASUS/Multimedia/ROG_XG_STATION2/ASUS-ROG-XG-STATION-2_V25.zip ). Connect the thunderbolt from your eGPU to your tablet and start FwUpdateTool.
Step 5. Download and install the latest drivers for your GPU.
After this you should be ready to enjoy your device.
Optional - Download and Install :
Hot plug tool ( http://dlcdnet.asus.com/pub/ASUS/Multimedia/ROG_XG_STATION2/ROG-XG-STATION-2_HotPlugTool_V0025.zip ) - the main program for your eGPU
Aura ( http://dlcdnet.asus.com/pub/ASUS/Multimedia/ROG_XG_STATION2/AURA_RGBLightingControlforGraphiccard-ROG-XG-STATION-2_v0055.zip ) - Control the RGB lighting.
As for cables, the first thing I wanted to do was to buy a longer cable, so after searching on this site, I ended up with a Caldigit 2m Thunderbolt 3 Active cable (100w, 40Gbps), but I was disappointed when I plugged in to the eGPU, because I was losing the connection every 10 sec or so. I had no error popping up, but the device manager was showing how the GTX 1060 was connecting/ disconnecting.
My next choice was a 2m Belkin Thunderbolt 3 Active cable (100w, 40Gbps), and this one works just like the 0.5m cable that came with the enclosure. I'll be sticking to this cable, because I have other uses for it, but does anyone know if I could have used a 2m Thunderbolt 3 20 Gbps passive cable? since I already have the H2D limitation.
Another cable that might work is the 2m Cable Matters Thunderbolt 3 100w 40Gbps Active cable or the 2m Akitito Thunderbolt 3 cable, but I couldn't find them in my country
Cuda-z and benchmarks
External Display - 0.5m cable
Internal Display - 2m cable
External Display - 2m cable
I have also tried out GTA V, Doom 1080p max settings and they run well at 50-60 fps, but I'm more than happy to play games like Bayonetta and Okami 4k, as well.
If you have other 2in1 devices with thunderbolt 3 ports, like the Lenovo miix 720, hooked up to an eGPU, please let me know about your experiences. I will update this thread if I find out anything else useful. Also, feel free to correct any wrong information. Thanks!
@Eugene, your CUDA-Z bandwidth results are unlike any other ones I have so far. They are higher than 2-lane TB3 (16Gbps-TB3), but lower than 4-lane TB3 (32Gbps-TB3) and don't match 20Gbps cable or GT2 underperformance numbers either.
Your system is listed as having a x4 3.0 (4-lane) TB3 controller here.
The performance would still be satisfactory.
If these bandwidth measures puzzle you too then, as both your pieces of equipment are from Asus, consider engaging their support to investigate the bandwidth underperformance. Here's a full bandwidth reference:
Great instructions, I already have an external 1080, which is what made me choose the t303au. Your instructions will save me some time.
I am hoping that it will play GTA V without external video under low settings when I am on the road. so I don't have to take my Alienware through the airport everytime. Have you tried GTA V without the external video on the T3 Pro?
Maybe this is a stupid question but can I use the external GPU if no external monitor is connected? If yes, how?
