Hello, any idea about my question?  😉  🙂 

Yes, it is shown as compatible here dell_docking_compatibility_guide.pdf.external

 

I have the Pro Max 18 Plus with iGPU only and that works flawlessly with my old WD19DC.

Yes, the SD25TB5 supports the Dell Pro Max 16 and 18 - has a 300w power supply. It seems to be the only current dock model that does. Compatibility matrix attached.

Thanks @SvenC and @Cadtot 🙂

 

@SvenC: I have a WD19S: do you think it could be ok for a Pro Max Plus 18 with RTX4000 ?

The WD19DC has two USB-C plugs and allows up to 210W. I guess the WD19S can only provide 130W, which is not even enough for the iGPU-only PMP18.

 

I would expect it to work if you connect your power adapter and the WD19S - so, periphery from the Dock and power from your power adapter.

I’ve only tested with the power supply connected and 1x usb-c connector from wd19dcs , this seems to work ok as a solution to not buy the new thunderbolt 5 dock but still not ideal as you have to remembered to take the 280W usb c power supply with you everywhere.

I’m trying to decide between the memory options for the Dell Pro Max 18 Plus.

 

From my workload, I’ve found that 96 GB RAM is the sweet spot. That leaves me with two possible upgrade paths:

 

• 128 GB CAMM2
• 96 GB CSoDIMM (2×48 GB)

 

I’m leaning toward the 96 GB CSoDIMM route since it’s much more cost-effective. But I’m wondering: aside from the extra 32 GB capacity, does CAMM2 offer any practical advantages I’d actually notice in real use?

 

Both configurations would be running at DDR5-6400 MT/s. Would there be any benefit in terms of performance, stability, or future-proofing by going CAMM2 instead of CSoDIMM?

I run two WD19DCs, one fully powering a Precision 7750 supporting two 4K screens, and the other supporting a Precision 7710.

• The 7710 uses one tail from the WD19DC to support one DP 4K screen, and I use HDMI to support the second 4K screen.

All works fine. :)

@AL123 Have you been able to test the TB5 dock to see if it reduces or eliminates battery drain with the higher 300W power delivery? I can see the CPU pl1 is dynamically set to 58W so combined with the 175W for the GPU seems like it's consistently too much.

I see that biggest factory csodimm configuration is 2x48.
But would it accept 2x64? How do you think?
