Yet another RAM upgrade thread 🤭

I bought some Corsair 16GB (1x16GB) DDR4 SODIMM memory recently (CMSX16GX4M1A2400C16). Turns out it isn't compatible with the XPS 9500. The tech support mentioned it was likely because of the lower clock speed (2666mhz).

On Crucial's compatibility list for this device, they show 2666mhz memory so I'm hesitant to trust the RAM mentioned there.

Before I go ahead, will Crucial Ballistix SODIMM DDR4 3200 32GB (2x16GB) (BL2K16G32C16S4B) be compatible with this device?

Thanks

Edit: Definitely can't trust that list - the Crucial RAM runs at 1.35v rather than 1.2v. Any suggestions for compatible RAM?

I'm now looking at (HX429S17IBK2/32) which according to some folks on Reddit is compatible - but that compatibility assurance comes at a £60 premium...
