Ok to add another 16gb kit of 8 Pack Team grp to make 32 or better to get whole kit?

Currently I have a new Ryzen 3700x on an old Strix B350-f board using a 16gb kit of the 8 pack 3200 MHZ team group RAM.

I'm pretty interested in the new MS Flight Simulator and while only in alpha it loosk like 32GB of memory could well be useful in that title.

I'm keen to work out if adding another 16gb kit (2*8gb) 8 pack kit and running 4 slots is likely to work well or if I'd be better to get a new 32GB kit using 16gb sticks. Not an expert on memory but I believe running 2 slots is ideal if possible and in some cases adding another matched timing set to an existing set can cause issues.

I'm just not sure how likely it is I might see problems adding another 16gb kit vs the added cost of buying a whole 32gb set. Any input and advice appreciated!
 
Make sure it's the same ram, with the same speed and timings ... If everything exactly the same, you'll be fine adding 16Gb more. Although just be aware that if you're overclocking the memory, the overclock will always be limited by the weakest ram silicon :)
 
That board has apparently T-topology DIMM slot wiring.
So except for more load on memory controller from two DIMMs (+ranks) per channel there won't be any additional challenges.
And Zen2's memory controller is certainly up to the job at 3200MHz.
Zen+ or especially original Zen would have been more stressed.

Good point. I'm on Ryzen 2xxx so slightly flakier memory controller... You may not even need the extra voltage with a 3xxx chip.
 
I was running two 16gb kits together for 32gb and they ran XMP just fine. However I couldn't get to 3733 with the two kits running together. The best I could get passed memtest was 3600 c14 with dram calculator subtimings. (~66.x ns) Even then, I still had some cold boot issues. I'm now running a single kit (2X8gb) @3800 + tightened timings (62.8ns). My benchmarks have gone up only slightly though. (Quad-rank interleaving on the old 32gb setup must have been helping a lot)

I don't think my x570 carbon is T topology though.

Yep, IIRC pretty much all X570 boards have daisy chained DIMM slots making them better for two DIMMs than four.
(technically best for two DIMMs would be board with only one slot per channel)
Though that shouldn't be yet that much limiting factor around 3600MHz according to Buildzoid.
But of course there's still variation from CPU/memory controller and DIMMs to another. (+possibly from motherboard model to another)
