Tuf X570 - Ryzen 3700X - But What RAM? Help Please

[midnight_lightning]

Hi,

I haven't done a new build for 5 yrs and things have moved on. I am looking at an ASUS TUF X570 board and Ryzen 7 3700X CPU, have spent 2 days looking at memory and still struggling.

I need a min of 32GB RAM for heavy duty Astro-photography processing and may add another 32GB at some point - so I'm thinking 2x16GB for now so I can add the same again if needed. I also do some heavy gaming. I have no intention of overclocking.

My short list includes:

• Corsair Vengeance LPX Black 32GB 3200 MHz AMD Ryzen Tuned DDR4
• Crucial Ballistix 32GB Kit (2 x 16GB) DDR4-3600
  
• Corsair VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3600MHz C18

I'm trying to keep RAM under £200 and could do with advice on the following:

• I want the fastest RAM for price and am aiming for 3600 but would 3200 be much different?
• The Ballistik 3600 i currently top of my list - but only because it is CAS16 where other 3600 in my price range seem to be Cas 18+
• Would CAS 16 3200 be better than CAS 18 3600 (or is it more complicated than that?)?
• What would you advise?

Sorry for so many questions, I knew a lot about this stuff in the 80's when I built my first PC but have got out of touch. btw I also intend to use a Samsung EVO 970 500GB NVMe for storage.

Cheers

PS - It doesn't really matter but I would rather not have lights on my RAM

I've not heard of this make and not much on google about them - is it an OC own brand - who makes them?

It is £50 (20%) more than the Ballistixs - why are they better?

Ok thanks. I've had to go with the Ballistix due to budget but would have gone with these otherwise.
