Area-51 R5/R7, 3200MHz, Dual Channel instead of Quad?
Is it a typo that the 64GB 3200MHz Memory is 'Dual Channel'? Or does the system actually not support Quad Channel 64GB 3200MHz Memory? I tried to find it in the service/specs manual but didn't see any clarification.
Thank you.

I suppose the first step is to pick a single machine and then identify it's exact chipset.

Even without knowing answer ... I think that current memory DIMMs are crazy fast (especially when running in Dual-Channel).

It's the Intel R7. How would the chipset answer my question? It clearly runs 2933MHz in Quad Channel. Maybe Dell cheapened up on the Memory or Motherboard RAM spec? Or maybe it's a typo.
If the 3200MHz is indeed Dual Channel, the question becomes is 2933MHz Quad Channel better than 3200MHz Dual Channel?

Because the chipset (on the motherboard) determines how many channels the memory runs at (when optimally configured).

I have the exact same question, and do not see any relevant reply. Why on earth would Dell set the motherboard to see 64GB 3200MHz Memory in Dual Channel rather than Quad Channel?

Just to clarify, the x299 chipset in the Area-51 support quad channel, the z370/z390 chipset in the r7 and r8 only support dual channel. So depending on the configuration of the Area-51 purchased, Dell may only populate so many memory slots. In order to run quad channel you must have a four stick matched set, you may run into issues if you have the dual channel configuration and try to add more later on. If Dell sells a 64GB dual channel setup for the x299 it has 2 x 32GB sticks. Newegg even sells them, I had to check.

Are you able to give us part numbers for the HyperX 3200MHz that works with the R5/R6 and also part numbers for HyperX 2933MHz.
