Hi,

I'm looking for some suggestions for my new 3900x, Gigabyte x570 Ultra.

I'm looking for 32gb.

Thanks.

Anyone tried these please?

Crucial Ballistix BL2K16G36C16U4B 3600 MHz, DDR4

No, but I've got the similar Crucial Ballistix 32GB (4*8GB) 3600MHz C16 kit and it works well on my Gigabyte X570 Master. Your kit should be more likely to work because 2 sticks are generally less stressful for the memory controller than 4. Just remember silicon lottery comes into play as anything over 3200MHz is technically overclocking so it depends on the quality of your CPU's memory controller.

Just remember to update your BIOS to the latest version as it has memory compatibility improvements.

Are you using this kit? BL2K8G36C16U4B

Tempted to run 4 of them myself because there are articles that say 4 sticks provide better performance than 2.

No, but they are similar, the code is BLE4K8G4D36BEEAK. Crucial have refreshed their entire range so you can't get the model I ordered (it has the old heatspreader).

Performance is related to number of ranks not necessarily number of sticks, 4 sticks of single rank RAM provide similar performance to 2 sticks of dual rank RAM which is better than 2 sticks of single rank RAM (the articles you read compared 4 sticks of single rank RAM to two sticks of single rank RAM, so dual rank vs single rank which is why you saw the performance difference; rank is calculated per channel:

(number of modules*number of ranks per module)/number of channels,

so 2 sticks of single rank on dual channel is (2*1)/2 = 1 rank overall while 4 sticks of single rank on dual channel is (4*1)/2 = 2 ranks overall, 2 dual rank modules would therefore be (2*2)/2 which is also 2 ranks overall.

16GB modules are all dual rank as far as I know whereas 8GB modules are generally single rank (mine included) so you are not losing any performance by getting 2 sticks of 16GB and they are easier to run than 4 sticks of 8GB. Whatever you do don't get 4 sticks of 16GB because then you have quad rank memory and good luck getting that to 3600MHz.
